Bohan Jiangandmultica-agent 8c9b7503a1 MUL-6146 fix(rerun): stop cancelling an in-flight agent run on manual rerun (#7282)
* fix(rerun): stop cancelling an in-flight agent run on manual rerun (MUL-6146)

RerunIssue cancelled every active task for the (issue, agent) pair before
enqueueing the replacement, including 'running' and
'waiting_local_directory'. That made a manual rerun destructive: asking an
agent for another pass silently killed the pass it was still working on.

Neither status appears in idx_one_pending_task_per_issue_agent_v2, so a
fresh queued row can be inserted alongside an executing one, and
ClaimAgentTask's per-(issue, agent) serialization already holds it there
until the active run reaches a terminal state. Narrow the cancel to rows
that have not begun executing and let the queue do the rest.

Rows that have not started are still cancelled and replaced rather than
reused, which keeps the new run attributed to the rerunning member
(MUL-4302 §5) instead of inheriting the attribution of whoever created the
pending row.

* fix(rerun): skip auto-retry when a manual rerun already holds the pending slot (MUL-6146)

Letting a manual rerun queue behind a running task opened a collision the
previous commit did not account for. If that running task then failed for a
reason whose retry child is created immediately (timeout, runtime_recovery,
codex_semantic_inactivity, skill_bundle_unavailable, or provider_network's
first attempt), CreateRetryTask inserted a SECOND queued row for the same
(issue, agent) and violated idx_one_pending_task_per_issue_agent_v2.

That insert shares FailTask's transaction, so the unique violation rolled the
parent's failed status back with it: the daemon's terminal callback saw a 500
and the task was left stuck in 'running'.

Guard both auto-retry paths with hasRunnableSuccessor. When something is
already pending for the pair, skip the retry — a runnable successor is exactly
what the retry was for, and the rerun is it. The FailTask check runs inside the
failure transaction so a concurrently committing rerun cannot take the slot
between check and insert.

runtime_offline and provider_network's final attempt were never affected:
retryDelayForAttempt defers those, and a deferred child is outside the index.

* fix(rerun): make the retry insert yield the pending slot instead of raising (MUL-6146)

The previous commit guarded both auto-retry paths with a successor check and
claimed the in-transaction check prevented a concurrent rerun from taking the
slot. It does not: hasRunnableSuccessor is a plain count at READ COMMITTED and
takes no lock, and rerun's cancel and enqueue are separate commits, so a rerun
can always commit between the check and the insert. The unique violation then
aborts FailTask's transaction, which also carries the parent's failed status,
leaving the task stuck in 'running' — the very bug the guard was meant to fix.

Move correctness into the insert: CreateRetryTask now yields via ON CONFLICT DO
NOTHING, so it can never abort its caller's transaction. That makes the policy
explicit — whoever already holds the slot keeps it, so a deliberate human rerun
wins over an automatic retry. Both callers read the resulting zero rows as 'no
retry created' and still commit their own work; this also stops the pre-existing
workspace-teardown fence from aborting a failure the same way.

For the reverse order, RerunIssue re-clears and enqueues once when a retry beat
it into the slot, so the human action still wins. Bounded to one extra attempt.

The successor checks stay as an optimisation, with comments corrected to say so
rather than claiming a mutual exclusion they never provided.

* fix(rerun): fence deferred promotion and recognise the normalized slot-taken error (MUL-6146)

Two gaps left by the previous commit, both reachable now that a manual rerun can
sit in the pending slot while a task is still running.

Deferred retries escaped the conflict fence entirely. runtime_offline and
provider_network's final attempt arm the retry as a 'deferred' row, which is not
covered by idx_one_pending_task_per_issue_agent_v2, so CreateRetryTask's ON
CONFLICT never fires and the row is created alongside the rerun. Promotion then
flipped it to 'queued' unconditionally and hit the index — and because the claim
loop promotes before it claims, that error blocked every claim on the runtime,
starving the rerun the operator was waiting for. Both promote queries now skip a
row whose (issue, agent) slot is occupied, and promote at most one row per pair
so a single statement cannot collide with itself. Skipped rows stay deferred and
promote on a later tick once the slot frees, so no retry is lost.

RerunIssue's reclaim only matched the raw pgconn violation, but
enqueueMentionTaskWithCommentPlan normalizes it to the bare
ErrDuplicatePendingTask sentinel — the path taken by every rerun whose target is
not the issue's current agent assignee (squad leader, an agent re-fired by
task_id after being displaced, a mentioned agent). Those never entered the
reclaim branch, so losing the race surfaced as a hard error. pendingSlotTakenErr
now matches both shapes.

* fix(rerun): cancel superseded deferred retries and tolerate promotion slot conflicts (MUL-6146)

Keeps the one product invariant this change exists for: one rerun click means
exactly one more run.

The previous commit only declined to promote a deferred retry while the slot was
occupied, and a test froze that as correct. It is not. Once the manual rerun
starts running it stops occupying the queued slot, so the stale retry promotes
and runs the agent a SECOND time — duplicate comments, duplicate side effects,
duplicate cost, and nothing anywhere to signal it. That also contradicted this
file's own 'a manual rerun replaces the pending plan' and FailTask's 'a runnable
successor already exists, so no retry is needed'.

A superseded deferred retry is now cancelled before promotion instead. Scope is
deliberately tight — retry clones only (retry_of_task_id set), never
assignee-fallback escalations or channel-media pending rows, which are supposed
to coexist with an active primary.

Promotion also tolerates the unique violation now. The in-query NOT EXISTS fence
cannot see an enqueue that has not committed yet, so promotion can still collide;
that is self-healing (the next tick sees the committed row) but the error used to
fail the claim outright, and for the batch path it failed every runtime in the
set. One contended row now skips promotion for a tick instead.

b4bfe083be MUL-6407: mint UUIDv7 primary keys for append-heavy tables (#7230)
* perf(db): mint UUIDv7 primary keys for the append-heavy tables

Random v4 primary keys scatter every insert across the whole primary-key
B-tree, so each row dirties a different page. On the tables that grow
continuously — the task queue, messages, comments, activity and audit rows —
that is pure write amplification. UUIDv7 puts a big-endian millisecond
timestamp in the leading 48 bits, so consecutive inserts share a page.

The 12 tables converted here are the append-only hot paths:

  agent_task_queue, activity_log, inbox_item, comment, issue, chat_session,
  chat_message, autopilot_run, webhook_delivery, task_token,
  channel_inbound_audit, sys_cron_executions

Ids come from the new pkg/dbid, which returns a pgtype.UUID ready to assign to
a sqlc params struct. Upsert-dominated tables (task_usage, agent_runtime, ...)
are deliberately left alone: v7 only buys locality for rows that are actually
inserted. Lease and claim tokens keep gen_random_uuid() — they must stay
unpredictable and carry no timestamp.

No migration, and no backfill. Every converted INSERT binds its id as
COALESCE(sqlc.narg('id')::uuid, gen_random_uuid()), so the column default stays
reachable: a caller that passes no id inserts exactly as it does today. Tables
will hold a mix of v4 and v7 ids permanently, which the uuid type and every
parser in the repo already accept.

Verification: - pkg/dbid: version/variant, uniqueness, and a non-decreasing timestamp
    prefix; a shape test asserting every converted query keeps the COALESCE
    fallback; and a source scan asserting every production params literal mints
    an id, so a call site added later cannot silently fall back to v4.
  - internal/handler: round-trips issue, comment, activity_log, inbox_item,
    chat_session, chat_message, agent_task_queue, task_token and
    channel_inbound_audit against Postgres and asserts the stored id is v7,
    plus one case proving an unset id still inserts (as v4).
  - internal/scheduler: covers the one hand-written INSERT, asserting the
    execution id is v7 while lease_token stays v4.

Wu Changming 7fdc854c26 fix(issues): copy durable local path for worktree tasks (MUL-6378) (#7176)
A worktree-mode local_directory task runs in a disposable git worktree that
Finalize removes on every exit path, so the task's `work_dir` pointed at a
directory that no longer existed. "Copy local workdir path" handed the user a
path they could not `cd` into.

The daemon now reports a `durable_work_dir` handoff instead of having clients
infer one:

- `removeLocalWorktreeDir` returns an error and confirms removal with `Lstat`,
  so a broken symlink cannot be mistaken for an absent directory. Finalize
  fails when removal cannot be confirmed.
- `durable_work_dir` is written only after Finalize succeeds and the worktree
  is verifiably gone. A preserved worktree, an in-place run, a running task, a
  squad-leader task, and any older daemon all leave it unset, keeping the real
  `work_dir` authoritative.
- The field travels on the complete, fail, and cancel-ack callbacks and is
  persisted on the task row (migration 362, additive nullable column). Writes
  use COALESCE for replay idempotency; the cancel-ack path CASes on
  `status = 'cancelled'` so a late ack cannot touch a completed or failed row.
- The server derives `relative_durable_work_dir` through the same
  home-stripping helper as `relative_work_dir`; the absolute value is reserved
  for explicit clipboard actions and is never rendered.
- Clients select the durable path only for a terminal task that carries the
  field. The issue actions menu and the transcript dialog share one resolver,
  and the label and toast say the task worktree was reclaimed, naming the
  delivery branch when one exists.

The stored path is a point-in-time delivery snapshot: later renames or
detachments of the project resource do not rewrite historical tasks.

97195885fa MUL-6350: rebuild the plugin system (2/4) — Action API + Surface + SDK (#7157)
* MUL-6350 feat(plugins): Action API and via-plugin attribution (2/4, part 1)

The server half of PR 2. A surface can now read and write through Multica, but
nothing renders one yet — the iframe host, SDK and example plugin follow.

Every Action API call passes three checks in order:

  1. the installation exists and is enabled — a surface left open in a stale
     tab stops working the moment an admin disables the plugin, rather than
     merely disappearing from the settings page;
  2. the installation holds the scope the endpoint needs, and the refusal names
     the missing scope so an admin can act on it;
  3. the SIGNED-IN USER may touch the resource.

Three is what makes the model safe, and it is deliberately not implemented
here: the workspace comes from the installation row rather than a client
header, membership is checked against that workspace, and the issue lookup is
scoped to it. A plugin therefore inherits exactly the reach of the person using
it, with no second copy of the permission rules to drift.

There is no plugin credential anywhere in this path. The iframe holds no token;
it posts a message to the host page, and the host re-issues the call on the
user's own session with a header naming which installation is speaking.

comment.via_plugin_id is the other half of that identity story: permission-wise
a plugin-mediated write is the user's, so author_type/author_id are unchanged,
but audit-wise it stays attributable to the plugin that produced it. Modeled on
comment.quick_action_id — no request field sets it, so it cannot be forged by a
member posting normally.

Two deliberate narrowings, both additive to widen later:

  - PATCH issues covers title and description only. Status, priority, assignee,
    parent, project and stage carry dispatch, catalog or hierarchy semantics
    that would need a second, drifting copy of those rules here.
  - A plugin-posted comment does not run @mention trigger dispatch. A plugin
    able to post a mention could start agent runs, and spend the workspace's
    budget, from a surface the user only meant to click a button in.

issue_panel and sidebar_panel flip on in HostCapabilities so an install stops
failing on a surface the host is about to be able to render.

* MUL-6350 feat(plugins): surface host, bridge and SDK (2/4, part 2)

The half a user can see. An installed plugin's issue_panel now renders on the
issue page and can read, write and store through the Action API landed in the
previous commit.

Isolation reuses the convention already in this repo for untrusted HTML
(packages/views/editor/code-block-iframe.tsx): sandbox="allow-scripts" and NOT
allow-same-origin, which the HTML spec calls out as the pairing that defeats the
sandbox. The frame gets an opaque origin — no cookies, no localStorage, no
access to the embedder, and no storage shared between two plugins. That is why
no separate plugin origin domain is needed.

The host generates the document rather than pointing the frame at the author's
HTML. That is what makes the net: scopes real: CSP is decided by whoever emits
the document, so an author-emitted page would carry its own server's policy and
the scope the admin approved would be a claim nobody checks. Here connect-src is
derived from the granted scopes, and a plugin with no net: scope gets
connect-src 'none' — it cannot phone home at all.

Identity on the bridge is bound by a MessagePort, not by event.origin: every
sandboxed frame reports the opaque origin "null", so comparing origins would
authenticate nothing. The host creates one channel per iframe, transfers one end
in, and only listens on the other.

Also here: @multica/plugin-sdk (zero runtime deps, no @multica/core or
@multica/ui import, since it ships to third parties), the hello-panel reference
plugin, and the bridge's own refusals — a path outside the Action API never
becomes a request, and a resize is clamped.

A local: install cannot render a surface: its files live on the server's
filesystem with no URL a browser could fetch, and the panel says so rather than
showing an empty frame.

Tests cover what a reviewer cannot see by reading the components: the CSP
derived from scopes, entry resolution refusing local and plaintext sources,
attribute escaping, the sandbox attribute never gaining allow-same-origin, the
bridge's path allowlist and status pass-through, and disabled installations not
mounting.

* MUL-6350 fix(plugins): give the SDK package a vitest config and protocol tests

A new workspace package inherits the repo's `test` script, so `vitest run` ran
with no config and no test files and exited non-zero — frontend-test went red
on a package that had nothing wrong with it.

Rather than only adding `passWithNoTests`, the guards now have the coverage they
warrant: they are the only thing between a hostile message and the bridge
handlers on both sides, so anything that is not exactly the agreed shape has to
fall through instead of being coerced into something close enough. Includes the
response/event mix-up, which would otherwise resolve a pending call with a theme
payload or apply a response as design tokens.

Co-authored-by: multica-agent <[email protected]>

* MUL-6350 fix(plugins): make the surface flow actually work end to end

Running a real plugin against a live stack found five defects that every test in
this PR passed straight through. Each one produced the same symptom — a blank
panel — and none was visible from reading the code.

1. The handshake raced in both directions. The host connected on the iframe's
   load event, which for a srcdoc frame can fire before React attaches the
   handler; and a guest that announced once could announce before the host was
   listening. The surface now announces until it is answered, and the host
   matches event.source against the frame it created. Origin cannot be used for
   this — every sandboxed frame reports "null".

2. The bridge was reused across a document change. close() is terminal, and the
   theme effect changed srcDoc, so the second connect() returned immediately on
   a permanently closed bridge. One bridge per rendered document.

3. The theme was read on first render, when the ref is still null, so every
   surface was built with no tokens at all.

4. X-Multica-Plugin-Installation was missing from corsAllowedHeaders, so the
   preflight failed and every Action API call from a browser client died as
   "Failed to fetch". The comment above that list warns about exactly this.

5. activity_log kept a via_plugin_id column in generated code from an earlier
   draft of migration 348 that no longer creates it — every issue timeline
   returned 500. Regenerated.

Also from seeing it rendered: frame-ancestors is dropped from the meta CSP
(ignored there, and the browser warns), and string config fields can declare
multiline so a value that is a list of lines gets a textarea instead of a
single-line input the user cannot read.

MULTICA_PLUGIN_DEV_ORIGINS lets an operator name an origin a manifest may be
served from while a plugin is being built, and a surface entry may resolve over
plain HTTP from loopback — what browsers already treat as a secure context.
Without both, a surface cannot be developed at all: there is no way to serve one
over public HTTPS from a laptop.

examples/plugins/release-checklist is the plugin this was verified with: a
per-issue definition-of-done checklist with workspace-configured items,
per-issue state in plugin storage, strict-mode gating, and a sign-off comment
that lands as the user with via_plugin_id set.

* MUL-6350 fix(plugins): close the bridge hijack, fix the capability gate, sync the comment path

Review fixes for #7157.

The security one first: the SDK accepted a bridge-init from any window and let a
later init replace the port. Sibling surfaces are mutually opaque, but
`parent.frames[i]` is an allowed cross-origin access — so another plugin on the
same issue page could deliver its own MessagePort, become a surface's "host",
feed it fabricated data and read everything it wrote, including whatever it put
in storage:user. The host already made exactly this check on the readiness
signal; the guest half was missing. Both examples carried the same hole, and
examples get copied.

The capability gate had flipped to enabling sidebar_panel with no mount point
anywhere — a plugin declaring one would install cleanly and then never appear,
which is the silent failure the gate exists to prevent. Turned back off, and a
test now asserts the shipped set matches what the host actually mounts, so the
next flip has to come with its renderer.

The two red tests were red for a real reason but were also written to break on
any capability flip. Rewritten to test the thing rather than today's set: the
message is asserted against an explicit empty Capabilities{}, and the live gate
against a kind that genuinely is not shipped (a hook). Added the other half —
a shipped surface must install against the real HostCapabilities.

A plugin-posted comment now publishes comment:created and re-opens a resolved
thread, like every other comment path. Skipping mention dispatch was deliberate;
skipping these two was not, and it is why the demo needed a page reload to see
the comment appear.

Corrected an overclaim rather than pretending to fix it: "no net: scope means it
physically cannot send data out" was wrong, because script-src necessarily
allows the author's own origin. net: bounds THIRD-PARTY destinations. img-src
and font-src are narrowed to inline data, which removes the two side channels
that need no scripting at all; the rest cannot close without re-hosting
third-party code, which this design rules out.

Smaller ones from the same review: the surface-error listener now checks window
identity too (any frame could light every panel's failure banner), the bridge
takes a method allowlist instead of any string, surfaces[].platforms is enforced
rather than decorative, and the iframe is keyed on the issue so a bridge created
for a new issue is not left waiting on a guest that already stopped announcing.

* MUL-6350 fix(plugins): drop the SDK's jsdom dev dependency and stub the window

`pnpm add -D jsdom` wrote a partial lockfile update: it resolved against a warm
local store, so `--frozen-lockfile` passed here and failed in CI on a vitest
peer key that was never written.

Rather than re-resolve, the dependency is gone. The SDK touches exactly
`window.addEventListener` and `window.parent`, so the handshake tests run on a
hand-built EventTarget in the node environment. A package that ships to third
parties is better off carrying no test-only dependency at all, and the tests
still fail without either guard they cover.

Co-authored-by: multica-agent <[email protected]>

* MUL-6350 fix(plugins): keep a test runner out of the SDK package

A new importer that pulls vitest through the catalog resolved to a peer key CI
could not satisfy on a clean install, so every frontend job died in
`pnpm install --frozen-lockfile` before running anything. Two attempts to
re-resolve it locally produced a lockfile that looked correct here and stayed
broken there — my store is warm, CI's is not.

So the SDK stops carrying a test runner at all. It ships as TypeScript source to
third parties and now declares only typescript plus the two workspace configs;
its handshake and protocol tests move to packages/views, its only consumer in
this repo, where the toolchain already exists. The lockfile delta for this whole
PR is now four workspace links and a typescript pin — nothing that can resolve
differently on a cold install.

The tests themselves are unchanged and still fail without the guards they cover.

6a17c00144 MUL-6350: rebuild the plugin system (1/4) — cleanup and foundations (#7144)
* MUL-6350 refactor(plugins): reset the plugin system to Action / Hook / Resource foundations

The V1 plugin system shipped 14 tables, an append-only revision log per
relationship, a capability-snapshot compiler, a per-task execution manifest
pinned by an INSERT trigger on agent_task_queue, release signing, trust tiers,
and a bundled catalog — and never left its feature flag. It holds no production
data, so this removes it outright instead of migrating it forward.

What replaces it, per the design in MUL-6338:

- A plugin relates to Multica in exactly three ways. Action (plugin calls
  Multica), Hook (Multica calls plugin), Resource (a static contribution with no
  call at all). "Who triggers" and "what capability is called" are orthogonal:
  a hook is declared once and lists which triggers may invoke it.
- We never execute third-party code. A plugin runs only in a sandboxed iframe in
  the user's browser or on the author's own server.
- Distribution is "install by URL, admin reads the scopes". No signature, no
  trust tier, no publisher verification — the scope list IS the trust decision.

This change is the foundation, with no user-visible surface yet:

- Decouples remote MCP first. RemoteMCPConnection/RemoteMCPTool/DigestBytes move
  into pkg/remotemcp, where they belonged; the protocol layer and daemon broker
  survive intact and dormant, ready to be rewired for the agent trigger.
- Drops all 14 plugin_* tables, their triggers, the manifest-composition
  function, and agent_task_queue.plugin_execution_manifest_id. Adds three:
  plugin_installation (one row per workspace+plugin, holding the manifest
  snapshot the admin consented to), plugin_storage, plugin_secret.
- Defines the manifest schema in full, once — surfaces, hooks with their
  triggers and events, resources, and a closed scope list. Parsing stays strict
  (DisallowUnknownFields, no trailing JSON). Contribution kinds this build does
  not ship yet fail installation loudly rather than installing half-working.
- Two-step install: preview parses and returns the scopes without writing, then
  install requires consent matching the manifest exactly. Manifest fetches reuse
  the remote MCP SSRF guard; MULTICA_PLUGIN_DIR adds a local source for
  self-hosting and plugin authors.
- Storage quotas are enforced on write and never by eviction. Secrets live in a
  separate encrypted table with no read path that returns a value.

* MUL-6350 fix(migrate): register the plugin index builds for invalid-index cleanup

Every migration that builds an index CONCURRENTLY must be registered in
concurrentIndexCleanups, or an interrupted build leaves a permanently INVALID
index that the `IF NOT EXISTS` retry records as success. TestEveryConcurrentUp\
BuildHasCleanup caught all three new plugin index migrations.

Co-authored-by: multica-agent <[email protected]>

* MUL-6350 fix(plugins): address review — byte quotas, version bound, secret pruning, script entry

From the review on #7144, plus one contract change the surface design forced.

- Storage quotas were accounted in characters and enforced in bytes. The usage
  query and the size_bytes it reports now use octet_length, and so do the
  plugin_storage column checks. A UTF-8 value could otherwise spend up to a
  quarter of the budget it appeared to.
- manifest version had no length bound while plugin_installation.version caps
  at 64, so a legal-but-long semver failed at INSERT as an opaque install
  error instead of a parse error naming the field.
- Upgrading pruned config values the new manifest dropped but left the matching
  plugin_secret rows. Ciphertext nothing can reach is exactly the residue
  pruneConfig exists to prevent; upgrade now prunes both in one transaction.
- SetConfig wrote secrets and config across two tables with no transaction, so
  a failed config write could leave a saved form half-applied.
- A duplicate first install mapped a unique-index violation to 502; it is 409.
- net: is now an exact host match. It was a suffix match in the hook transport
  check while the same scope becomes an exact-host CSP connect-src in the
  surface runtime — one scope string cannot mean two things across the two
  places the consent screen claims to describe.
- surfaces[].entry must be a .js/.mjs script, not an HTML document. The host
  generates the surface's document so it can attach the CSP derived from net:;
  a plugin-authored document would carry its own server's policy and net: would
  be a claim rather than a control.

Tests: the three storage limits get a canonical unit matrix plus DB-backed
coverage of the byte counting and the exclude-the-candidate-key replacement
semantics; upgrade-time secret pruning is pinned end to end (verified failing
without the fix); and the admin-only routes now have a real middleware-level
403 check, which every direct-handler test bypassed.

c9727e6b2b feat(daemon): worktree mode for local_directory resources (MUL-5707) (#6759)
* feat(daemon): worktree mode for local_directory resources (MUL-5707)

Local directory resources serialise every task on a per-path mutex, so two
tasks on one folder queue behind each other. This adds an opt-in worktree
mode: each task gets its own git worktree of the user's repo inside the
daemon's env root, so tasks run concurrently and deliver their work as a
branch instead of editing the user's working copy.

Opt in per resource with execution_mode=worktree (default stays in_place,
so existing resources are unchanged). Requires a git repo with at least one
commit; a non-git directory fails with an actionable message rather than
silently falling back to serial execution.

Design points that make the mode safe to use:

- The agent starts from what the user sees, not HEAD. Tracked edits are
  captured with `git stash create` (which writes a commit object without
  touching the index, working tree, or stash list) and replayed into the
  worktree; untracked non-ignored files are copied, bounded at 2000 files /
  200MB with the skipped count logged at warn level.
- That replayed state is committed as a baseline, so "did this task change
  anything?" has an exact answer and `git diff <baseline>..<branch>` is
  precisely the agent's work.
- Nothing is silently discarded: leftovers are committed to the branch
  before the worktree is removed, including when the task fails partway.
- A task that changes nothing leaves no branch behind.
- Sidecars stay out of the branch by running the existing
  CleanupRuntimeConfig + CleanupSidecars pass over the worktree before
  finalizing. The .git/info/exclude approach repocache uses is not usable
  here: a linked worktree resolves info/exclude to the user's own common git
  dir, so it would change what `git status` hides in their checkout.
- Worktree-mode env roots do not get the local_directory GC exemption, so
  they age out normally instead of accumulating one env root per task.
- `git worktree prune` on create self-heals registrations orphaned by a
  crashed daemon.

Adds --execution-mode to `project resource add/update`, and updates the
docs and the projects-and-resources built-in skill.

* fix(daemon): close data-loss and isolation gaps in worktree mode (MUL-5707)

Review follow-up on #6759. Six issues, all on failure or skew paths.

1. Preserve work when the final commit fails. Finalize logged a warning and
   then ran `git worktree remove --force`, destroying the agent's changes.
   commit.gpgSign with no key available to the daemon triggers this, and
   --no-verify does not disable signing. Finalize now returns an error and
   deliberately keeps the worktree — it stays registered, so `git worktree
   list` points at the work — and the daemon fails the task instead of
   reporting success with a branch that is missing the changes.

2. Fail closed on an unsupported execution_mode. Treating an unknown mode as
   in_place was wrong: execution_mode is how a user asks for ISOLATION, so
   the "safe" fallback would edit the working copy they asked us to stay out
   of. An unrecognised mode now fails the task naming the version skew.

3. Keep Codex conversations alive across turns. The per-issue session store
   was keyed on LocalWorkDir != "", so worktree tasks — which also never
   reuse an env root — got a fresh empty CODEX_HOME per turn and silently
   lost the thread. Covered by a two-turn regression test that fails without
   the fix.

4. Fail closed on an incomplete snapshot. A failed stash create/apply, a
   failed untracked copy, or hitting the copy bounds all degraded to "agent
   sees HEAD" with only a daemon log line. A half-replayed tree looks like a
   working checkout, so nothing downstream questions it while the agent reads
   different code than the user has. All of these now abort the prepare and
   tear the partial worktree back down.

5. Do not snapshot a directory mid-mutation. The same real path can be
   attached to another project as an in_place resource; snapshotting under a
   running in_place task captured a half-written tree plus that task's
   in-flight .agent_context/.multica sidecars, which then reached the branch
   and could feed the agent another issue's brief. Worktree prepare now takes
   the per-path mutex for the snapshot alone (released before the run, so
   tasks still overlap), and the untracked replay skips Multica's own
   sidecars.

6. Stop the test helper from masking regressions. gitRun skipped on any git
   failure, including post-finalize assertions, so a lost branch could report
   as a skip. Git availability is now checked once at repo setup; every later
   git failure is fatal.

Also rebased onto main, keeping both MulticaConfigRoot and LocalWorktree in
the Environment initialiser.

* fix(daemon): close sidecar-commit and wait-visibility gaps in worktree mode; gate worktree saves on daemon version (MUL-5707)

- runTask: register the sidecar-cleanup defer immediately after the Finalize
  defer. Previously two early returns (temp-dir setup, StartTask failure) sat
  between them, and on those paths Finalize auto-committed the sidecars
  Prepare had just written — delivering a branch whose only content is
  Multica's own runtime files (in_place: leaving them in the user's tree).
- runTask: give the worktree snapshot wait the same plumbing as the in-place
  acquire — waiting_local_directory status, resourceWaitTasks accounting, and
  a cancellation poller. The holder can be an hours-long in_place task; the
  wait was invisible and a user cancel went unnoticed until the 5-minute
  prepare timeout.
- isMulticaSidecarPath: match sidecar dirs as whole path segments at any
  depth, not only at the repo root. An in_place resource pointed at a
  SUBDIRECTORY leaves its sidecars below that subdirectory; replaying them
  committed another issue's brief into the delivered branch.
- handler: refuse saving execution_mode=worktree while the owning daemon's
  registered cli_version is below MinLocalWorktreeCLIVersion (422,
  daemon_version_unsupported). An old daemon json-skips the field and runs
  tasks IN PLACE — the daemon-side unknown-mode refusal cannot protect a
  daemon that predates the field, so the server has to. Residual (documented):
  a daemon downgraded after the save needs a claim-time gate.
- copyUntrackedFiles: read the -z listing raw instead of TrimSpace-ing it,
  which corrupted filenames beginning/ending with whitespace into paths that
  silently vanished from the replay.
- docs + skill: describe the save-time version gate; drop the stale claim
  that old runtimes fail the task themselves.

* feat(views): UI switch for local_directory execution mode (MUL-5707)

Worktree mode shipped CLI/API-only, which for its target user — someone
running several tasks at once from Desktop — means it does not exist. This
adds the switch to the resources panel.

The choice is framed by what the user gets back, not by the mode
identifiers: "Edit this folder directly" (one task at a time, changes land
in your working copy) vs "Run in parallel, isolated" (tasks run at the same
time and each hands back an agent/… branch). `in_place` / `worktree` stay
visible as a secondary hint for anyone cross-referencing the CLI or docs.

Two entry points, matching where the decision is actually made:

- The add-a-folder flow now asks for the mode after the folder is picked and
  validated, instead of creating the resource and leaving the mode to be
  discovered later.
- Every local_directory row has a mode control. It is deliberately NOT gated
  on being the owning machine — switching the mode only rewrites a field, so
  it works from the web app too, unlike rename or the folder picker.

Both blocked states are handled where the user chooses, not after they
commit:

- Non-git folder: the desktop validator now reports whether the path is
  inside a git working tree (walking up for `.git`, so a subdirectory of a
  repo counts), and the option is disabled with that reason. Unknown — an
  older desktop build, or an existing row — stays permissive; the daemon
  re-checks authoritatively.
- Daemon too old: the version floor is mirrored from the server as
  MIN_LOCAL_WORKTREE_CLI_VERSION and checked against the runtime for the
  resource's OWN daemon, not the machine the browser happens to be on. A
  server rejection is rendered inline in the dialog rather than as a toast,
  so the dialog stays actionable.

A "Parallel" badge on the row is always visible (not hover-only): without it
there is no way to tell whether tasks on a folder edit it directly or hand
back a branch, which is the first thing anyone asks when a task queues.

Also adds `execution_mode` to LocalDirectoryResourceRef — the field existed
server-side but had no TypeScript counterpart — and brings the zh/ja/ko
project-resources docs in line with the English ones, which were the only
locale updated when the mode landed.

* fix(daemon,handler): close worktree isolation and delivery gaps (MUL-5707)

Second review round. Five must-fix items, all on paths where the mode's
promises could still break.

1. A failed sidecar cleanup no longer ships Multica's own files as the
   user's branch. The cleanup errors were logged and Finalize then ran
   `git add -A`, so a permission/disk/lock failure could deliver a branch
   whose entire content was the runtime brief and issue context. Worktree
   mode now escalates a cleanup failure to an abort: nothing is committed,
   the worktree is kept for inspection, and the task fails with the
   preserved path. In place it stays a warning — no commit, no branch, and
   the leftovers are visible in the user's own tree.

2. The untracked replay no longer drops files silently. `Lstat` failures
   and symlinks were `continue`d without counting, so the caller read a
   partial snapshot as complete. Both now count as skipped, which the
   existing fail-closed check turns into a refused prepare. Non-content
   entries (sockets, FIFOs, devices) stay uncounted deliberately.

3. Prepare rolls back a worktree it created. Any later failure — context
   files, provider home, MCP config — returned without an Environment, so
   nothing downstream knew a worktree existed, leaving a registration and
   a branch no task ever ran in. A deferred Discard now runs unless Prepare
   reached its successful return.

4. The daemon-version gate moved to where it can actually hold. Save-time
   validation cannot see a machine downgraded afterwards, and an old daemon
   json-skips execution_mode entirely — it would run the task in place,
   editing the working copy the user asked to isolate. Claims are now
   checked against the runtime that is actually claiming, and a blocked
   task is cancelled with a reason rather than left to be redelivered to
   the same too-old runtime forever.

5. branch_name is delivered end to end. The daemon sent it, but
   TaskCompleteRequest had no field so it vanished at decode, and the
   failure path never sent it at all. It now has a column, travels on both
   terminal callbacks, and renders as a copyable row in Run details. The
   failure path matters most: worktree mode commits the agent's leftovers
   before tearing the worktree down, so a run that died partway still has
   work worth finding.

Docs (all four locales) and the projects-and-resources skill are updated
for the claim-time gate and the branch surface.

* fix(handler,daemon): migration renumber, cancel reasons, branch on every terminal path (MUL-5707)

Third review round.

1. Rebased onto main and renumbered the migration to 285 — main had taken
   273 and is now at 284. sqlc regenerated on top of the rebased queries;
   the conflicts were confined to generated files.

2. The claim gate now persists why it cancelled. It called CancelTask,
   which writes only status='cancelled', and returned the reason as a 4xx
   that reaches the daemon's log and nothing else — batch claim drops the
   task from its response entirely. A run refused for a durable reason the
   user has to act on cannot present as a bare "cancelled", so this adds
   CancelAgentTaskWithReason and records error + failure_reason on the row.

3. branch_name now survives every terminal path, not just the two direct
   callbacks. Three were dropping it:
   - the context-exhausted complete→fail reroute did not copy it;
   - the daemon's complete→fail fallback (server rejected the complete,
     agent had succeeded) did not set it;
   - both cancellation paths discarded the result wholesale, even though
     the worktree is finalized — and its work committed — before the daemon
     learns of the cancel. The branch now rides the cancel-ack and is
     recorded by SetAgentTaskBranchName, which never overwrites a name a
     terminal callback already wrote.

4. Rollout/rollback compatibility. Isolation is enforced by two server-side
   gates, so a daemon downgraded at any point after the resource was saved
   is caught. The gap they cannot close is rolling the SERVER back past this
   change while sub-floor daemons are still connected: an old server has no
   gate and an old daemon ignores execution_mode. That constraint is now
   documented where an operator will meet it (the migration and the docs),
   and the version floor is pinned across server and frontend by test so the
   two gates cannot silently drift apart.

* fix(server,views): route claim-gate cancels through TaskService, make cancel reasons visible, harden cancel-ack branch delivery (MUL-5707)

Closes the fourth-round review findings on worktree mode's cancellation
chain:

- Claim gate: cancel through a new TaskService.CancelTaskWithReason instead
  of a raw CancelAgentTaskWithReason query, so a gate-cancelled task gets the
  full cancellation side effects — audit capture, chat settle, agent status
  reconcile, task:cancelled broadcast, NotifyTaskFinished. Added REAL claim
  integration tests: singular claim (422 + row cancelled with reason), batch
  claim (task omitted + row cancelled with reason), and a current-runtime
  control.
- Cancel reasons are now user-visible: execution log rows, agent activity
  rows, and the transcript dialog label a SERVER-cancelled task (persisted
  error/failure_reason) like a failed one, with the actionable text on hover
  and a Reason row in Run details. User-initiated cancels stay a plain
  "Cancelled". New cancelReasonLabel helper + local_directory_error label;
  details_reason locale key in en/zh-Hans/ja/ko; widened
  AgentTask.failure_reason to the open string the wire actually carries.
- Cancel-ack is now a terminal delivery: the daemon retries it on transient
  errors (same schedule as complete/fail), the server fails LOUD (5xx) when
  persisting the branch/error fails instead of warn-and-200, and re-broadcasts
  task:cancelled after a successful write so clients that already refetched a
  branchless row pick up the delivery. Replays are idempotent (never
  overwrite).
- Cancel + Finalize-abort no longer swallows the preserved-worktree pointer:
  the finalize error is wrapped in worktreePreservedError (joined onto an
  existing run error, never displacing it), extracted on the cancel path, and
  delivered via the ack into agent_task_queue.error through the new
  SetAgentTaskErrorIfEmpty query — never overwriting a reason recorded by a
  fail callback or the claim gate. Other run errors on a cancelled run stay
  discarded as before: they are expected noise.
- Docs: the self-hosted rollback constraint callout now exists in zh/ja/ko,
  not just English.

* fix(handler): guard cancel-ack writes to cancelled rows; requeue when the claim gate's cancel fails (MUL-5707)

Fifth-round review fixes:

- SetAgentTaskBranchName / SetAgentTaskErrorIfEmpty now carry a
  status='cancelled' CAS. The daemon acks on EVERY terminal status it
  observes, so a late or replayed ack from a stale run could previously
  backfill its branch or preserved-path error into a completed/failed row
  whose own callback — the authoritative channel — recorded nothing, without
  any event invalidating the change. A CAS-refused write is a deliberate
  no-op (still 200: nothing to retry), and the rebroadcast stays guarded by
  the same status check. Regression tests: a late ack against a completed row
  with empty fields and against a failed row leaves both untouched.
- When the worktree claim gate's CancelTaskWithReason fails, the claimed row
  no longer strands in dispatched (daemon refused, nothing to release it but
  stale reclaim). The gate requeues via RequeueTaskAfterClaimFailure — the
  next claim re-runs the gate and retries the cancel — and reports 5xx so the
  singular daemon reads a transient server problem, not a claim refusal; the
  batch path omits the task as before, now with the row requeued. Fault
  injection tests (row-scoped trigger raising on the cancel UPDATE while
  letting the requeue through) cover singular and batch.

c4f0d8cc8c MUL-5999: make workspace teardown index-driven, bounded and fenced (#6754)
* perf(workspace): make teardown task discovery index-driven

Workspace teardown found a workspace's tasks with a three-way
`OR agent_id IN (…) OR issue_id IN (…) OR runtime_id IN (…)`, three times
per delete, and swept task_token with the same shape. PostgreSQL costs
that as a Seq Scan on agent_task_queue — the largest table in the
database (5.08M rows / 8.3 GB in production) — so deleting even a tiny
workspace paid for the whole table, inside the transaction that holds the
workspace row lock and global advisory lock 4246.

Resolve the task set one owner key at a time instead, in the handler, and
reuse that snapshot for every task-keyed step. Measured on a 1.2M-row
synthetic copy of the production shape (937 agents / 109 issues / 12
runtimes): the OR form and a 937-element `= ANY(array)` form both Seq
Scan; single-key equality is a Bitmap Index Scan. A UNION of parent-key
joins is worse than the OR (three hash joins, each seq scanning the
table), which is why that earlier suggestion was dropped.

All three ownership paths are preserved: nothing enforces that a task's
agent, runtime and issue share a workspace, so dropping a path would turn
a performance fix into a tenant-cleanup bug.

task_token needs no loop. Its workspace_id has been NOT NULL since
migration 108, so the workspace key alone covers this workspace's rows,
and the two extra OR arms only ever matched tokens owned by another
workspace whose task or agent lives here — both NOT NULL FKs with
ON DELETE CASCADE, so the later task/agent deletes remove exactly those.

Two indexes make the new shapes index-eligible:

- 273 agent_task_queue(runtime_id): every existing runtime_id index is
  partial, so all-status consumers had none. This also covers the FK's
  own ON DELETE CASCADE probe, which runs per deleted agent_runtime row
  on the ordinary delete path.
- 274 task_token(workspace_id): the column has never been indexed.

Measured block usage for the same workspace, before → after:
agent_task_queue discovery 25,665 → 14,485 blocks; task_token sweep
4,086 → 3 blocks. The point is not the ratio at this size but that the
cost now scales with the workspace being deleted instead of with the
global table.

* fix(workspace): fence, bound and un-cascade the teardown task sweep

Addresses all four blocking findings from the MUL-5999 review.

1. Concurrency (correctness / tenant isolation). The task set is no longer
   a lock-free snapshot reused across steps. Teardown now locks every row
   through which a task can belong to the workspace — its agents, issues
   and runtimes — FOR UPDATE, and holds them for the rest of the
   transaction. Inserting an agent_task_queue row takes FOR KEY SHARE on
   each referenced owner, which conflicts with FOR UPDATE, so a concurrent
   enqueue (or a reassignment onto one of these runtimes) can no longer
   slip a task in behind the sweep. Locking the tasks alone could not do
   that: a row that does not exist yet cannot be locked. This is the same
   technique the handler already uses on the workspace row to keep
   CreateChatSession out of the delete window.

   The per-batch page query also takes FOR UPDATE, so under READ COMMITTED
   PostgreSQL re-checks ownership after each lock: a task a concurrent
   commit already moved elsewhere is skipped rather than deleted on a
   stale claim, and a task we locked cannot move before we delete it.

   Deadlock (40P01) joins lock_timeout (55P03) as a retryable 503, because
   the owner locks can be taken in the opposite order by a concurrent task
   update.

2. Cleanup ownership (no cascade reliance). task_token keeps all three
   explicit paths, split into separate index-driven statements instead of
   one OR: workspace_id in DeleteWorkspaceLeafData, task_id in
   DeleteTaskBatch, agent_id in DeleteTaskTokensByAgent. Nothing in the
   teardown graph now depends on ON DELETE CASCADE to finish the job.

3. Bounded memory. The whole-workspace task array is gone. The sweep pages
   through one owner key at a time with LIMIT 1000 and deletes exactly the
   page it read, so process memory, the array parameter and each DELETE's
   row count are bounded by the batch size rather than by a workspace's
   lifetime task count. The task-keyed arms moved out of the leaf-data
   statement into DeleteTaskBatch, which runs per page, and the separate
   whole-workspace task delete is gone.

4. Migration retryability. The concurrent-index cleanup hooks are now
   derived from a version -> index-name map that covers 257, 261 and
   273-277, so an interrupted CREATE INDEX CONCURRENTLY cannot be mistaken
   for success on retry.

Three more indexes, each an unindexed FK referencing column that the
per-batch statements need and that the FK's own ON DELETE action already
scanned per row on ordinary deletes: task_token(agent_id),
chat_draft_restore(task_id), autopilot_run(task_id).

Plans re-verified on a 1.2M-row synthetic copy of the prod shape with the
child tables populated: page query is a Bitmap Index Scan under LockRows;
task_usage, chat_draft_restore, task_token and autopilot_run arms are all
index scans.

Tests: the ownership-path test now asserts the sweep is self-sufficient
inside the transaction, before any owner row is deleted, so a cascade
cannot stand in for teardown. New tests cover the enqueue / reassignment
fence (blocked writers, unrelated writer unaffected), multi-page sweeps
and the page bound, plus a migration-retry repair test and a check that
every cleanup hook names the index its migration builds.

* fix(workspace): keyset-page the teardown sweep and fail closed on leaks

Addresses the second review round on MUL-5999.

1. Bounded scan, not just bounded result. The page query was
   `owner = $1 ORDER BY id LIMIT n` against indexes that cannot produce id
   order, so the executor had to read the owner's whole task set before
   applying LIMIT — quadratic in pages for a busy owner, which is the case
   this issue is about. Measured on a 550k-row probe: the old shape spent
   11,630 buffers per page (planner chose a full pkey index scan; on other
   statistics it chose an explicit Sort), the keyset shape spends ~2,000
   and a later page costs the same as the first.

   Pages are now `owner = $1 AND id > $cursor ORDER BY id LIMIT n` against
   composite indexes: 273 becomes (runtime_id, id), 278 adds (agent_id, id),
   279 adds (issue_id, id) and 280 drops the single-column issue_id index it
   supersedes so the hot table does not carry both.

2. Owner enumeration is bounded too. The three LockWorkspaceTaskOwner*
   statements no longer return ids at all — they are a set-based write fence
   and now cost the API process nothing. Owners are walked separately in
   keyset pages of 500 (281-283 add the (workspace_id, id) indexes those
   pages need), so a workspace with a huge agent or issue set never has its
   whole owner list held in memory.

   The keyset column is id rather than a natural key on purpose: a cursor
   column must be immutable, and renaming an owner mid-teardown would
   otherwise let it sort behind the cursor and escape the sweep.

3. The fence is no longer the only guarantee. Blocking a concurrent enqueue
   still relies on an INSERT taking FOR KEY SHARE on the owner rows it
   references, which is a property of the legacy FKs rather than a protocol
   every enqueue path opts into. Two things now backstop it:

   - every owner is re-swept until a pass finds nothing, and teardown fails
     closed (rolling the whole transaction back) if tasks keep arriving,
     instead of committing a partially cleaned tenant;
   - a schema-contract test asserts the three owner FKs still exist, so a
     migration that removes them turns the missing fence into a red build
     rather than a silent hole.

   An explicit deleting-state protocol shared with all seven enqueue paths
   remains the right long-term fix and is out of scope here.

End-to-end teardown, real handler, identical synthetic data, main vs this
branch (1.2M-row agent_task_queue, 200k task_token, 300k task_usage):

  small workspace, 5k tasks:   29,247 ms -> 1,013 ms   (4.38M -> 0.27M blocks)
  busy workspace, 60k tasks:  243,863 ms -> 1,724 ms   (5.76M -> 2.23M blocks)

* fix(workspace): fence task writes in-transaction, independent of the FKs

Addresses the third review round on MUL-5999.

1. The re-scan did not close the window, and the reviewer is right that it
   cannot: a pass that comes back empty returns success, and a task
   inserted after that final scan but before COMMIT is not caught by any
   number of passes. The only thing that closed that window was the
   FOR KEY SHARE an INSERT takes on the agent / issue / runtime rows it
   references — a side effect of foreign keys that workspace_delete.sql
   itself documents as an expand-phase net a later contract removes.

   Migration 284 replaces it with an explicit fence: a BEFORE INSERT OR
   UPDATE OF (agent_id, issue_id, runtime_id) trigger on agent_task_queue
   that takes FOR KEY SHARE on the workspace row behind every owner the row
   references, and raises if one is gone. That conflicts with the FOR UPDATE
   LockWorkspaceForDelete already holds for the whole teardown transaction,
   so a task write against a workspace being torn down blocks until teardown
   finishes and then either proceeds (rolled back) or fails closed
   (committed).

   A trigger rather than a per-call-site check because the fence has to be
   in the same transaction as the write: there are seven INSERTs and several
   ownership-changing UPDATEs across agent.sql, autopilot.sql, chat.sql and
   runtime.sql, several of them single autocommit statements, so a separate
   "take the fence" statement from the caller would be its own transaction
   and protect nothing. In-transaction by construction, covers every current
   path, and cannot be forgotten by a path added later.

   TestTaskWriteFence_BlocksOnWorkspaceLockAlone isolates the fence from the
   FKs: the holder locks ONLY the workspace row — no agent, issue or runtime
   row — so no FK on agent_task_queue has anything to block on, since none of
   them references workspace. Inserts through all three ownership paths and a
   reassignment all block; an unrelated workspace's insert and a status-only
   update still pass. Dropping the trigger fails that test.

   Cost, measured with 5,000 bare inserts: 147 ms without the fence,
   238 ms with it — about 18 us per inserted row for up to three indexed
   lookups and a shared row lock. It does not fire on the hot claim /
   dispatch / complete path, which updates status and timestamps rather than
   ownership.

   The verification passes stay as a self-check, no longer described as the
   concurrency guarantee.

2. Migration 280 is withdrawn. Its down path rebuilt the superseded index
   with CREATE INDEX CONCURRENTLY, and the runner only runs INVALID-index
   cleanup hooks in the up direction, so an interrupted rollback would leave
   an invalid index that a later `down` skips — and rolling back 279 too
   would then leave no usable issue_id index at all. The redundant
   single-column index stays for now; dropping it needs its own migration
   with a direction-aware cleanup. This also settles the stale comment in
   task_usage.sql, which still names the old index and remains correct.

3. Keyset cursors no longer start from the all-zero uuid, which is itself a
   valid uuid and would have made a row with that id invisible forever.
   Every walk now has an explicit first-page query with no cursor predicate.

* fix(workspace): move the task-write fence into the write statements

Addresses the fourth review round on MUL-5999.

1. The trigger is gone. Migration 284 now defines
   lock_task_owner_workspaces(agent_id, issue_id, runtime_id), a predicate
   that every statement writing agent_task_queue ownership calls in its own
   WHERE clause:

       INSERT INTO agent_task_queue (...)
       SELECT ... WHERE lock_task_owner_workspaces($1, $3, $2)

   Nine statements now carry it: the seven task INSERTs (agent.sql x5,
   autopilot.sql, chat.sql), LinkTaskToIssue, and ReassignTasksToRuntime —
   the last through a MATERIALIZED CTE so a bulk UPDATE evaluates the
   VOLATILE predicate once instead of per row. Clearing runtime_id is
   exempt: it cannot move a task into another workspace.

   Calling it from the writing statement keeps the lock in the writer's own
   transaction, which a separate caller-issued statement could not do for
   the autocommit enqueue paths. TestTaskOwnershipWritesCallTheFence is the
   trade for dropping the trigger: it scans the query files and fails the
   build if a statement writes ownership without the fence.

2. The fence no longer defers to the foreign keys. The trigger version
   counted only owner references that still resolved, so a deleted owner
   made itself invisible: with all three gone it returned early, and with
   one of three gone the count still matched. The predicate now compares
   resolved owners against the number of owner arguments supplied and
   returns false on any mismatch, so a stale write is rejected on its own
   terms. TestLockTaskOwnerWorkspaces_RejectsUnresolvableOwner covers each
   shape, including the one-of-three case.

3. Deterministic lock order. The workspace rows are locked with
   ORDER BY w.id, so mirrored cross-workspace writes cannot take the same
   pair in opposite orders. Honest note on the test: 25 mirrored concurrent
   pairs never deadlock either way, because the current plan happens to
   return the rows in a stable order — the ORDER BY is what makes that a
   guarantee rather than an accident of the plan, and the test is a
   regression test for the symptom.

4. The fail-closed test now tests what its name says. The previous one only
   inserted a neighbour-owned task and could not have failed. The
   replacement runs the actual race: a writer calls the real
   CreateAgentTask, blocks on the workspace lock, teardown deletes the
   workspace and commits, and the writer must come back with pgx.ErrNoRows
   — the fence's own verdict. An FK doing the work instead surfaces as
   SQLSTATE 23503, which the assertion rejects explicitly.

Cost: 5,000 predicate calls in 53.7 ms, about 11 us per fenced write, for
up to three indexed lookups and a shared row lock. Status, dispatch and
completion updates do not call it.

* fix(runtime): stop the legacy merge when the task fence refuses

Addresses the P1 from the fifth review round on MUL-5999.

ReassignTasksToRuntime returned only a row count, so a fenced refusal was
indistinguishable from "the old runtime had no tasks". mergeLegacyRuntimes
read both as success and went on to DeleteAgentRuntime(old), where
agent_task_queue's ON DELETE CASCADE silently took the history the
reassignment exists to preserve — and once that FK goes away, the same path
would instead leave tasks pointing at a deleted runtime. Either way the
merge was leaning on the cascade, which is what this PR set out to stop.

The query now returns the fence verdict alongside the count:

    SELECT (SELECT ok FROM fence) AS fence_ok,
           (SELECT count(*) FROM reassigned) AS reassigned_tasks

and the merge is a single helper, mergeLegacyRuntime, that aborts with
errRuntimeMergeFenced before touching anything else when fence_ok is false.
Tasks now move FIRST, because that is the step carrying the fence: nothing
else in the merge — agent reassignment, legacy daemon_id bookkeeping, the
old runtime delete — runs unless the fence agreed. The next daemon
registration re-runs the merge, by which time the workspace is either gone
or its teardown rolled back.

TestMergeLegacyRuntime_KeepsOldRuntimeWhenFenceRefuses covers it: with a
vanished merge target the old runtime and its task both survive and the task
stays on the old runtime, while a merge onto a live runtime still completes.
Removing the abort fails that test — and fails it with SQLSTATE 23503 from
agent_runtime_id_fkey, which is precisely the "an FK is doing the work"
shape the review objected to.

Also replaced the fixed 300 ms sleep in the queued-writer race with a poll
on pg_stat_activity for a backend actually parked on a lock, so the test
cannot pass without the race being set up (it now fails on timeout instead).

* fix(runtime): make the legacy runtime merge a single transaction

Addresses the P1 from the sixth review round on MUL-5999.

The merge ran four autocommit statements, so the fence's workspace lock
ended with the statement that took it. Two ways that left a tenant
inconsistent while daemon registration still reported success:

  * a transient failure on the agent reassignment committed the task move
    and nothing else, leaving tasks on the new runtime and their agents on
    the old one until some later registration happened to retry;
  * in the gap after the task commit, a workspace teardown could lock and
    delete the target runtime — and its UnbindTasksFromRuntime step clears
    runtime_id on exactly the tasks that had just moved. The next merge
    looks tasks up by the OLD runtime id, so that history was detached for
    good.

mergeLegacyRuntime now opens a transaction and runs the whole merge on one
qtx: fenced task reassignment, agent reassignment, the legacy daemon_id
audit write, and the old-runtime delete, then commits. The fence stays the
first statement, so the workspace lock it takes is held until COMMIT — a
teardown cannot start deleting the target mid-merge — and the lock order
against teardown is unchanged. Any failure returns an error and rolls the
whole thing back.

The audit write is no longer best-effort: inside a transaction a failed
statement poisons the rest, so it either lands with the merge or the merge
is abandoned.

TestMergeLegacyRuntime_RollsBackWhenAStepFails injects the failure in the
database rather than through a code seam — a trigger makes the agent move
raise — and asserts the task, the agent, both runtime rows and the audit
column are all exactly as they were, then that the same merge completes
once the injection is removed. Reverting to autocommit fails it with
"task moved to <new runtime>; the task reassignment was not rolled back".

Also took the non-blocking suggestion: the queued-writer race now has the
writer report its own pg_backend_pid() over a channel and waits for that
specific backend to park on a lock, instead of matching statement text
against every backend on a shared test database.

* fix(runtime): fence late writes against the runtime a merge is collapsing

Addresses the P1 from the seventh review round on MUL-5999, which the
reviewer reproduced rather than inferred.

The fence locked the workspace row and nothing else. A task write takes
FOR KEY SHARE there, and so did the legacy runtime merge — and two KEY SHARE
locks do not conflict. So an enqueue against the OLD runtime went straight
through after the merge had scanned its tasks, and DeleteAgentRuntime then
removed that brand-new task through agent_task_queue's ON DELETE CASCADE.
Making the merge one transaction widened the window rather than creating it:
the agent's new runtime_id is invisible until COMMIT, so concurrent writers
keep resolving the old runtime for the whole merge.

Both sides of the contract now lock the owner rows too, in one order:
workspace rows (by id), then agent, issue, runtime.

  * lock_task_owner_rows (migration 284, renamed from
    lock_task_owner_workspaces) takes FOR KEY SHARE on each owner row after
    the workspace rows, and re-checks that they still exist. That is what
    conflicts with a delete.
  * The merge takes FOR KEY SHARE on the workspace and then FOR UPDATE on
    both runtime rows in id order, before the task scan, and holds them to
    COMMIT. FOR UPDATE is the level that conflicts with a writer's KEY
    SHARE; both runtimes in one ordered statement so two merges running in
    opposite directions cannot take the pair in opposite orders. Locking
    fewer rows than asked for means one disappeared, and the merge is
    abandoned.

A late writer therefore either commits before the merge takes the lock — in
which case the scan that follows sees its task and moves it — or waits, and
then finds the runtime gone and writes no row.

TestRuntimeMerge_LateWriteToOldRuntimeIsFencedNotCascaded drives the merge
statement by statement so it can stop where the window was (after the agent
update, before the old runtime is deleted), enqueues against the old runtime
through the generated query, and requires that the writer is parked on a
lock, that it comes back as pgx.ErrNoRows, and that the merge's own history
ends up on the target. It explicitly rejects both 23503 and a row that
lands and then vanishes.

Both halves are load-bearing: dropping the runtime lock from the fence, or
the FOR UPDATE from the merge, fails that test — the latter with "the late
write was rejected by a foreign key (23503), not by the fence".

Cost: 5,000 predicate calls in 74.4 ms, ~15 us per fenced write (was ~11 us
with the workspace lock alone).

* docs(workspace): correct the fence comment and drop a trailing newline

Two review nits, no behaviour change.

lockWorkspaceTaskOwners still described migration 284 as a BEFORE trigger on
agent_task_queue. It became a called predicate, lock_task_owner_rows, in
9fc1d79, and this comment is the place someone reads to understand how the
fence works — so it now says what it is: a predicate every ownership-writing
statement calls in its own WHERE clause, taking FOR KEY SHARE on the
workspace rows and then the owner rows.

Also removed the blank line at EOF in the migration, which git diff --check
was flagging.

0c69f1f95f fix(daemon): recover in-turn when a resumed session cannot resolve provider auth (#6798)
A resumed Hermes session whose persisted provider identity can no longer
resolve its credentials fails with the SDK's "Could not resolve authentication
method" message. The server-side resume guards already blacklist that session,
so the NEXT turn starts fresh and succeeds — which is exactly why Chat
alternated success / failure instead of staying broken (GH #6777).

Curing the failing turn needs the daemon's in-turn fresh-session retry, which
never fired: nothing identified this error as fatal-to-resume. Add it as a
third form of positive evidence in shouldRetryWithFreshSession, alongside
ResumeRejected and UnresumableHistory.

Deciding in the shared gate rather than in each ACP adapter is what makes it
correct and narrow:

- priorSessionID != "" already proves the run was a resume, which is the whole
  distinction between "the session's provider copy is broken" (curable) and
  "the credentials are wrong" (not curable). An adapter cannot tell those
  apart from the error text alone, which is why Result.ResumeRejected still
  documents auth errors as out of scope.
- The failure surfaces at session/resume, session/set_model (MUL-5029
  provider re-routing, the likelier path on a resumed session) and
  session/prompt; only two carry any resume-failure signal today. The final
  error text carries the phrase on all three.
- tools == 0 is untouched, so a turn that already acted is never replayed.

The phrase now has a single home in taskfailure.AuthMethodUnresolved, shared
with ResumeUnsafeFailure. The SQL guards stay as-is: they are the only
protection for rows written by a daemon too old to have this retry.

5a618e0925 fix(agents): stop resuming a session that can't resolve its provider auth (MUL-5803) (#6482)
* fix(agents): stop resuming a session that can't resolve its provider auth

A Hermes agent on a self-hosted install can get permanently stuck on a single
issue while every other issue on the same agent keeps working. The task
terminates with:

  hermes provider error: "Could not resolve authentication method. Expected
  either api_key or auth_token to be set. Or for one of the X-Api-Key or
  Authorization headers to be explicitly omitted"

and no amount of retry / Rerun recovers it.

Root cause (resume-pointer poisoning): every daemon version classifies this
text as agent_error.unknown, which is resume-safe. So GetLastTaskSession /
GetLastChatTaskSession keep returning the same failed session to every retry
and Rerun on that (issue, agent) pair, deterministically reproducing the auth
error forever. Other issues use fresh sessions, so they're unaffected — the
codebase's repeated "(agent, issue) permanently stuck" pattern (GH #6066 /
#5760 / #6360, MUL-5722), with this error falling through every prior defense.

The fix rests entirely on text guards; the classifier is deliberately left
untouched. Reclassifying this under missing_config would flip freshSessionMayHelp
to false and silently disable the in-turn fresh-session retry on the five
ResumeRejectionUndetectable backends — contradicting the (correct) diagnosis
that a fresh session cures it:

- service/task.go ResumeUnsafeFailure: text guard so manual Rerun and the
  fallback claim path start fresh rather than replaying the dead session.
- GetLastTaskSession / GetLastChatTaskSession SQL: ILIKE exclusion so
  already-wedged issues recover on their next trigger without a daemon upgrade.

Tests pin both halves: a freshSessionMayHelp regression (must stay true for
this error), the Go ResumeUnsafeFailure cases, and SQL exclusion + narrowness
regressions for both query families.

b99b04bb86 feat(onboarding): Mika issue-first onboarding (#6378)
* feat(onboarding): Mika issue-first onboarding

Replaces the starter-agent welcome with one conversation: onboarding creates
Mika, the workspace's built-in Chief of Staff, and opens a real chat whose
first turn is a product-authored kickoff hidden from the transcript. Every
workspace — first and subsequent — is created through this flow.

Mika is a system agent, not an agent-template instance. Her product prompt is
//go:embed-ed and composed at claim time, so a release updates it without
touching any workspace's row; the row holds only the workspace's own notes.
Creation is server-owned and idempotent under a per-workspace advisory lock,
and archiving a system agent is rejected.

This is the pre-merge half of the branch, squashed while rebasing onto main.
Replaying its fifteen commits individually meant re-deriving each one against
a main they were never written for; the net change reconciles against today's
main in four files, so it is reconciled once, here.

Three of those four are main moving under the branch: MUL-5573 took
quick-actions generation server-side and dropped QuickActionsDisabled /
RegenerateQuickActionsFor from the task payload and the SendDirectChatMessage
signature, so this takes main's shape and keeps only the onboarding entry
point. The fourth keeps main's OnboardingLogoutButton wrapper around the
flow's new mode/onCancel props.

* feat(onboarding): let quick-action chips carry the opening's examples

Chat now renders agent-suggested follow-up actions as buttons under a reply
(MUL-5149), and the onboarding kickoff qualifies for that suggestion pass
with no extra wiring — it is a direct chat turn on a web session with a
non-empty reply.

That made the opening's fourth beat redundant: Mika wrote a three-to-five
line menu of example tasks, then three chips appeared underneath offering
the same thing. The prose menu is the worse half — a member has to retype a
line they read, but can send a button — so the beat is gone and the opening
budget drops with it. Measured on a real local run: the first reply went
from 307 to 208 characters, and the chips still arrived 21s after the
kickoff.

The questionnaire profile stays in the kickoff. The suggestion pass resumes
the same provider session, so the profile now steers the chips as well as
the reply; only the sentence naming its purpose changes.

* refactor(onboarding): cut the step rails down to what the screen can't already show

The right rail carried more than twice the words of the column members were
actually working in — 42 vs 36 on the workspace step, 91 vs 34 on the runtime
step — and it got heavier the further in the flow went, which is backwards.

Step 3's rail was the clearest case. Its "Good to know" section promised the
runtime was swappable and that more could be added later; the step's own lede
already said both in nine words rather than forty-two, on the same screen. Its
60-word definition of "agent runtime" sat beside a list of named, online
runtimes under a headline reading "This computer is connected" — by then it
answers a question the member has stopped asking. What survives is the one
thing the screen does not show: what that background process is.

Step 2's rail keeps the workspace preview card, which does show something not
otherwise visible, and drops the bullet lists — promises the product is about
to keep on its own.

The freed words did not move to the rail; one moved into the main column. On
the create path "Mika" was never introduced before Step 3 used the name twice,
once on the primary button, so the lede now names the role in an appositive
right above that button. Mika stays ungendered, as everywhere else in the
product.

Net across the three regions: 167 words to 89.

Co-authored-by: multica-agent <[email protected]>

* refactor(onboarding): drop the right rail from the workspace and runtime steps

Every remaining rail item was either something the screen already showed or
something the product was about to do anyway, so the column was costing a
member's attention without answering a question they had. Removing it leaves
each step a single full-width column — the shape the questionnaire step has
always had, and the only step nobody has complained reads as sparse.

Gone with it: RuntimeAsidePanel, the workspace preview card and its entity
rows, and 27 copy keys per locale. The two runtime paths (desktop
runtime-connect, web platform-fork) shared that panel, so both lose it in one
move and stay identical.

The welcome step keeps its column — it holds an illustration, not prose.

Co-authored-by: multica-agent <[email protected]>

* fix(onboarding): put every step's header and content on one measured axis

Removing the right rail left the four steps geometrically inconsistent in
four ways, all of which the member sees as things moving while they advance.

The header carried the horizontal padding itself, so it ran flush to the
window edge while the content column stayed centred. A 480px rail had been
absorbing that difference; without it the two were 267px apart on a 1283px
window, and since StepHeader is justify-between the step indicator floated
off at the far right, ~270px from anything it labelled.

The rest compounded it: the measure changed between steps (920px on the
questionnaire, 620px after), the header bar and content block used different
vertical padding per step, and padding living inside a max-w box made the
reading width jump from 508px to 620px at the lg breakpoint.

All four now come from step-shell.tsx. Padding belongs to the gutter, never
to a measured box, so the reading width is constant from ~700px up. The
header measures on STEP_FRAME on every step, so the one element that survives
each transition never moves; content picks STEP_FRAME or STEP_COLUMN by what
it holds, and both centre, so a step that needs the width still sits on the
header's centreline. Vertical rhythm is one value.

The header was near-identical in four files, which is how it drifted in the
first place, so it is now one component. Its test pins the invariant that
broke — padding out of the measured box, header measured on the frame — and
fails if either is put back.

Co-authored-by: multica-agent <[email protected]>

* fix(onboarding): give the runtime step the frame measure and cut its copy

Nine runtimes in a 620px column meant truncated names, five rows, and
scrolling to reach the last four, with ~330px of dead space on each side.
This is the case step-shell's wider measure exists for, so the step takes
STEP_FRAME — which also puts it on exactly the header's measure — and the
card grid gains a third column at lg. Nine runtimes now land in three rows.

Copy went with it. The headline was two sentences over two lines; the first
one, "This computer is connected", is already said louder by the "9 agent
runtimes · all online" row directly beneath it, so only the instruction
remains. The lede was 44 words and five lines — I had grown it myself adding
Mika's introduction — and is 20 now, still naming the role. The
remote-computer note drops from 25 words to 15.

Prose stays capped at 620px inside the wider frame; a 920px measure is for
the card grid, not for reading.

The found-phase test keyed on the headline copy, so a copy edit read as a
behaviour regression. It now asserts the runtime count row, which is the
signal the test is actually about.

Co-authored-by: multica-agent <[email protected]>

* refactor(onboarding): put the workspace step on the shared frame

It was the only step still measuring at STEP_COLUMN, so its eyebrow, headline
and footer CTA started and ended ~150px inside where every other step's did —
the page margins visibly moved when you advanced from step 1 to step 2.

The step now sits on STEP_FRAME like the other two, with a new STEP_MEASURE
capping the prose and the form inside it. Matching the frame is not the same
as widening the field: a workspace name does not want an 800px input, so the
form keeps its reading measure and left-aligns to the frame instead. The
footer row spans the frame, which is what puts the CTA in the same place on
all three screens.

STEP_MEASURE deliberately does not centre — centring would pull the content
off the frame's left edge, undoing the alignment. Its test pins that.

Co-authored-by: multica-agent <[email protected]>

* fix(onboarding): close the gap above the step CTA and put Log out back on one row

Two defects that read as one thing on screen: a large empty block sitting
directly above the primary button.

The card list was capped at STEP_MEASURE along with the form. That cap exists
so a workspace name does not get an 800px input — a good reason for a text
field and a bad one for selection cards, which are a list like the runtime
grid. Capped, they stopped 299px short of the CTA, leaving a void above the
button. The cards take the frame now; only the form keeps the reading measure.

Log out came in from main as `fixed right-8 top-8`, pinned to the window
corner. Its own comment says the fixed position exists to survive the flow's
full-bleed layouts — which is what the measured frame replaced, so it landed
outside the measure and above Back / Step N of N as a second header row. It
now rides the header row on the frame.

StepShellHeader takes it as a `trailing` slot rather than rendering it:
calling useLogout inside the shared header forced a QueryClient into five
step test files just to render a header bar. The flow injects it, matching
how runtimeInstructions is already threaded, and the header stays
presentational.

* feat(onboarding): make step 3 about Mika, with the runtime as a sub-decision

The step was titled after its dependency — "Pick an agent runtime" — while
the thing actually being created was named only in the grey lede. A member
reached a button reading "Start with Mika" without having been told who that
is, and said so: being confused there is not a failure to read carefully, it
is the page putting the lead role in a footnote.

So the subject changes rather than the step count. The headline names the
outcome, a card carries the introduction with a mark on it, and the runtime
list drops to a labelled sub-section under "Where should Mika run?". Reading
order becomes: who you are getting, she needs a machine, pick one, start.

MikaIntro sits above the phase switch so the subject holds still while the
runtime block below cycles through scanning / found / empty, and each phase's
own heading drops from h1 to h2 now that the page has a real h1.

Mika does not exist yet at this point — she is created on commit — so the
card cannot render her stored avatar. It reuses the mark the Runtimes page
already uses for "Start with Mika", so the two entry points read as the same
thing.

No fourth screen: the introduction and the only decision on this screen are
one beat, and splitting them would add a step between finishing setup and the
payoff. The defect was never a missing screen, it was an invisible
introduction.

Co-authored-by: multica-agent <[email protected]>

* feat(onboarding): pick the runtime and the model from dropdowns

Nine runtimes as cards took three rows and left nowhere to put a second
decision. Two dropdowns fit both on one screen, and the model is a real
choice the card grid had no room for.

Both controls already existed on the agents surface — RuntimePicker and
ModelDropdown, the same pair create-agent-dialog uses — so this reuses them
rather than growing a parallel picker. ModelDropdown owns its own discovery,
grouping and unsupported-runtime states, and selecting a different runtime
clears the model because models are per-runtime.

The model now reaches the agent: POST /api/agents/mika takes an optional
model, CreateSystemUserAgent writes it to the column the agent table already
had, and empty still means "whatever the runtime defaults to" — which is what
every deployment without per-agent model support gets anyway.

Also drops the "No local runtime, or prefer a remote computer?" note. It said
in twenty-five words what the Skip button next to it says by existing, and it
appeared on all three phases.

currentUserId comes in as a prop rather than from the auth store: reading the
store inside the step broke six tests that render it without one, the same
coupling the header slot avoided.

* fix(onboarding): stop gendering Mika in the intro card

Mika is ungendered everywhere else in the product — the agent instructions,
the onboarding skill and every other locale string avoid a pronoun. The intro
card I added last round reintroduced one in two languages ("she turns it into
an issue" / "她会把它变成一个 issue"), which the Chinese screenshot made
obvious. All four locales now read around it.

* feat(ui): port the ReUI stepper primitive

Groundwork for rebuilding onboarding on the @reui/onboarding-3 interaction
model: a persistent vertical stepper with named steps and click-to-return
navigation, which our horizontal "Step N of 3" dots cannot express.

Routed to components/ui rather than the vendor's components/reui namespace —
it is our code now — and rewritten to the role-named type scale (text-xs ->
text-caption, text-sm -> text-label / text-caption, dropping the leading-none
the token already supplies). No other convention fixes were needed: shadcn had
already rewritten the imports, "use client" survived because main's
components.json now sets rsc: true, and it pulls no npm dependency we do not
already have (@base-ui/react is declared).

The block's other twelve registry dependencies are primitives we already own,
so only this one was installed.

Co-authored-by: multica-agent <[email protected]>

* feat(onboarding): rebuild the step shell as a named progress rail

Onboarding's chrome was a row of dots and a "Step 2 of 3" counter. It told
a member how much was left but never what was coming, so every step arrived
unannounced -- the same reason the runtime step read as a surprise even after
it was retitled "Meet Mika". Naming all three steps up front makes onboarding
legible as a whole before the first field is filled in.

StepShellHeader becomes StepShell, and it owns the window rather than a strip
at the top: rail on the left, the step's own content scrolling on the right.
That lets the four steps drop an identical wrapper/DragStrip/header/<main>
preamble, including the scroll-fade wiring that was duplicated verbatim in
all four and is now set up once.

The rail is built on the ported ReUI stepper, but deliberately not as a
tablist: that component defaults to role=tablist with each trigger owning
aria-controls on a panel id, which is right for a stepper that renders its
own panels and wrong here, where the panel is a routed step and those ids
would dangle. It uses the presentational slots and marks position with
aria-current instead.

Only completed steps are clickable -- moving forward has to run the current
step's validation and submit, so the rail would skip it. New-workspace mode
gets no rail navigation at all: it enters at the workspace step and, once
that workspace exists, every step behind it is gone. Same invariant
runtimeStepBack already enforced for the Back button.

step_header.step_of is replaced by step_nav across all four locales; Mika
stays ungendered in each.

* feat(onboarding): standardise the steps on the shared UI primitives

Follow-up to the rail, fixing what the rail exposed.

The workspace form was three hand-rolled `flex flex-col gap-1.5` stacks with
their own label sizing and a bare <p> for the slug error -- exactly what
Field/FieldLabel/FieldError/FieldDescription standardise. The manual version
had already drifted: its labels were caption-sized and muted while every
other form in the product labels at body weight.

The platform fork wrapped on STEP_COLUMN while the steps before it wrapped
on STEP_FRAME. Both measures centre, so 620px and 920px put their left edges
~150px apart and the headline visibly jumped right on arrival. It now sits on
the frame and caps its own content, which is the pattern step-shell already
documents.

The About you eyebrow read "About you" -- now the rail's label for that very
step, so the page said its own name twice, once in grey caps and once in the
headline under it. Dropped, along with the locale key. The other steps keep
theirs because they say something the rail doesn't ("Connect a computer",
"Workspace creation is disabled").

Log out is `inline` on every step, and inline now means "on the rail", which
is an inverted surface -- the muted/destructive pair it used unqualified is
mixed from the light palette, so it was rendering as near-invisible grey on
black.

e2e: the smoke spec asserted "Step 1 of 3", text the rail replaced. It now
asserts the rail's named steps and which one is aria-current, and carries on
into the runtime step so all three get captured. Two pre-existing bugs in
that spec surfaced while fixing it: the zh-Hans case pinned its locale cookie
to a hardcoded port, and it advanced with getByRole("button").first(), which
is the pinned Log out button -- so that case had been signing the user out
and asserting against a login redirect.

* feat(onboarding): rebuild the rail as the ReUI inset panel

The first pass kept the block's idea -- a named vertical rail -- and dropped
most of its structure. Side by side with onboarding-3 the gap was obvious:
no brand lockup, no inset panel, no texture, steps jammed against the top
edge, numbered chips instead of the ring/check/dot progression, stub
separators instead of one continuous track, and a bare Log out where the
block has a footer row.

This ports the structure properly:

- Inset panel -- the aside carries the padding and the panel is rounded with
  a hairline ring, instead of a dark rectangle bleeding to the window edge.
- Brand lockup top-left (the existing MulticaIcon plus a wordmark), Back
  demoted to an icon button top-right, which is where the block puts it.
- Step list centred in the remaining height rather than stacked under Back.
- Indicators follow the block: filled + check when done, ring + dot when
  current, faint ring when upcoming. Numbers move to sr-only text, since the
  ring already encodes position and the digit was redundant next to a label.
- One continuous hairline behind each row instead of a stub between rows.
- DotSphere ported to packages/ui as the panel's texture. It is decorative,
  reads no product state, and already honours prefers-reduced-motion.

Two fixes fell out of doing it properly:

`.dark` is a plain class selector in our token sheet, so scoping it to the
panel redefines the custom properties for that subtree and `bg-background` /
`text-muted-foreground` mean the right thing inside it. That replaces the
hand-mixed `text-background/60` shades of the first pass -- which is what had
made Log out near-invisible -- and it is why the button is back on ordinary
tokens here.

StepperSeparator hardcodes a 3rem height for vertical navs, so an absolutely
positioned track overshot its row and drew the line straight through the next
indicator. Overridden with the same variant rather than !important, so
tailwind-merge drops theirs.

DotSphere cycles three constant arrays by `index % length`. Under
noUncheckedIndexedAccess that is `T | undefined`, so they are typed as
non-empty tuples and index 0 is the fallback -- no non-null assertions.

* feat(onboarding): put the content pane on the block's type and layout

The rail matched onboarding-3 and the pane it sat next to did not, so the
two halves read as different products: serif display headlines and a grey
uppercase eyebrow on the right, the block's sans hierarchy on the left.

Typography now maps onto the block exactly, and it lands on our scale
without rounding -- ReUI's `text-xl/7` heading is our `text-title-lg`
(20/28) and its `text-sm/5` supporting line is our `text-body` (14/20).
StepHeading owns both, so no step hand-rolls a headline again.

The eyebrows are gone. The block has no such slot, and with the rail naming
every step, a grey uppercase label above a headline saying the same thing
was the third name for one screen. The workspace step's disabled-state
wording was the only eyebrow carrying information the headline lacked, and
that variant already exists as its own headline copy.

Geometry collapses from three competing measures -- a 920px frame, a 620px
column, an in-frame cap -- to one 28rem column. Three measures is what let
the platform fork sit ~150px right of every other step. STEP_MEASURE stays
for capping a single control inside the column.

Actions move into StepFooter: full-width, stacked, pinned to the bottom of
the column. In a 28rem column the old right-aligned inline bar left the
primary action floating mid-screen instead of where the eye finishes the
form. The column is `min-h-full` rather than centred by the pane, because
`items-center` on a scroll container clips the top of anything taller than
the viewport and these steps do overflow on short windows.

Questionnaire options become the block's wrapping chips. They were
full-width cards in a 4-column grid; inside a 28rem column that grid had
nowhere to go, and stacking all 18 as rows turned one screen into a long
scroll. Chips are the block's own answer for a many-option question. This
also reaches the workspace source-backfill prompt, which shares the
component -- intentionally, it is the same question in the same style.

MikaIntro moves onto StepHeading + Item for the same reason.

* fix(onboarding): drop the rail clear of the macOS traffic lights

The rail is a dark inset panel and it started at the window's top-left
corner, which is exactly where macOS draws the traffic lights -- so the
close/minimise/zoom buttons sat on top of the dark surface.

The underlying mistake was structural. The desktop shell rule asks for a
single DragStrip as the first flex child of a full-window view; this had two
hand-rolled strips instead, one inside each pane, and neither was first. The
sidebar's was 28px of internal padding trying to duck under the traffic
lights from inside a panel that had already begun above them, which cannot
work -- the panel's own background was the thing being overlapped.

One DragStrip now spans the window above both panes. The panel starts below
it (48px strip + the aside's inset, measured at 64px on a wide window against
traffic lights that end around 32px), the whole band stays draggable, and the
two ad-hoc strips are gone.

* fix(onboarding): make every block in the column share one width

Reported on the workspace step: the name field ended short of the
description above it. Measured rather than eyeballed -- the heading,
description and footer all render at 448px, the form at 384px, because the
FieldGroup still carried STEP_MEASURE.

STEP_MEASURE made sense against the old 920px frame, where a full-width
input would have been absurd. Against a 28rem column it does nothing but
misalign, so both remaining uses are gone -- the workspace form and the
runtime picker -- and the constant with them. A single measure that no step
can locally narrow is the whole point of the column; leaving the knob
exported invites the same drift back.

Two stale measures went with it. The runtime phase views still capped their
ledes at max-w-[620px], inert inside a 448px column, and sized them
text-body-lg against StepHeading's text-body; their h2 was text-title-lg,
the same size as the h1 above it. Both now match the shared scale.

Guarded in e2e rather than a unit test. The shell test renders a stub child,
so asserting "no narrow cap inside the column" there would pass whatever the
real steps do. The new spec walks all three steps and compares rendered
geometry -- it fails on the reported bug and passes after the fix, which is
what makes it worth keeping.

* fix(onboarding): stop the whole window re-fading on every step change

Every step rendered its own <StepShell>. Because each step is a different
component type, React tore the shell down and built a new one on each
transition: the "persistent" rail remounted, its canvas restarted, and the
shell replayed `animate-onboarding-enter` -- a 0.4s fade from opacity 0
across the entire window. That full-window re-fade is the flash.

Measured before changing anything: tagging the live <aside> and switching
steps showed the attribute gone, and the shell root still reporting
animation-name `onboarding-enter` after the switch.

The upstream block has no step-change motion at all -- no animate-*, no
transitions, no framer-motion, no AnimatePresence. Its sidebar and section
live in one component and only the step body swaps. This does the same: the
flow owns a single StepShell and the steps render content. The shell's
entrance fade now runs once, on entering onboarding, which is what it was
for.

`backDisabled` was the one thing blocking the hoist -- the shell needs it but
only the workspace step knows the create request is in flight. It reports
upward through `onBusyChange`, with an unmount cleanup: a successful create
advances immediately, so without clearing the flag the next step would open
with Back and the rail dead.

Guarded in e2e by tagging the rail and content nodes and asserting they
survive a step change, plus a single DotSphere canvas rather than one per
visited step.

* i18n(zh): retranslate onboarding and fix cross-file inconsistencies

Reported as "生硬" on the onboarding Chinese. Reviewed all 217 onboarding
strings against the Chinese voice guide in conventions.mdx, then swept the
other 24 locale files for the same classes of problem.

Three were mistranslations, not stiffness. The worst: an agent runtime was
described as the AI coding tool "我们接管的" — take over — where the English
says "we connect to". Also a "推荐" that exists in no source string, and
"12 calls" (user interviews) rendered as "12 通电话".

Punctuation, decided from the repo's own zh docs rather than guessed:
「」 is forbidden by the guide and appeared 16 times; 破折号 spacing was
split 26 spaced vs the rest unspaced, and the docs run 152 unspaced to 35,
so unspaced wins. Four strings had a stray space inside Chinese text
("正在跳转到 工作区").

67 English strings had two or more Chinese translations. Most are
legitimate — weekday pickers use single characters where labels spell them
out, 飞书/Lark are deliberate regional variants, and "Name" is 姓名 for a
person and 名称 for an object. 42 were arbitrary and are now unified.

ja/ko got the same consistency pass on the clear-cut cases only, kept
parallel with the zh choices. Their punctuation was deliberately left alone:
「」 is standard Japanese quoting, so the zh rule does not transfer.

Edits are applied to the raw file text rather than through a JSON
round-trip, which reformatted compact one-line objects and turned ~20 real
edits into a 97-line diff.

* feat(mika): use the unicorn emoji as Mika's placeholder avatar

Mika shipped with a hand-rolled data-URI SVG — a sparkle glyph on a dark
rounded square — which only that one constant knew how to produce. Agents
already have an emoji avatar convention (`emoji:` marker in avatar_url,
owned by agentEmojiAvatarPrefix on the server and parseAvatarEmoji on the
client), so this reuses it instead: ActorAvatar renders the emoji as text and
no surface needs to special-case her.

The two cards that stand in for Mika before the agent row exists move with
it — the onboarding intro card and the Runtimes "Start with Mika" card. Both
were drawing the same sparkle mark, and leaving them would mean a member sees
one face during onboarding and a different one the moment Mika is created.
They now share MIKA_PLACEHOLDER_EMOJI, which carries a pointer to the server
constant so the two cannot drift apart silently.

The dark square went with the sparkle: it was built to frame a white line-art
glyph, and an emoji on it reads badly. These use bg-muted, matching how
ActorAvatar already frames an emoji avatar.

Placeholder until Mika has real artwork.

* i18n: stop the skip path promising things it does not do

Two claims in the runtime-skip copy that the code does not back, both found
while walking the flow end to end.

"Enter your workspace in read-only mode" — there is no workspace read-only
concept on the server. The only READ ONLY in handlers is Postgres transaction
isolation on the issue-table and search queries. What actually exists is
admission.go's ReasonAgentRuntimeRequired, which blocks dispatch when no
runtime is connected. So the sentence's second half was already true and
enforced; the first half promised a restriction that does not exist — a
member who skips can create issues, comment, edit fields and invite people
exactly as normal. Same over-claim in cloud_waitlist.intro_warning.

"We've added one task" — the skip path creates an *issue* (it lands on the
Issues board as NOR-1), and task/issue are distinct entities in this product.
Now says issue.

All four locales.

* i18n: reframe Mika as your first agent teammate

Requested copy change on the step 3 headline.

The rail's description for that step moves with it. It is the step's own
subtitle and sits on the same screen as the headline, so leaving it saying
"Your Chief of Staff" would have put two different framings of Mika side by
side on one page.

Three "Chief of Staff" references are deliberately untouched, because
dropping the title everywhere is a positioning call rather than a copy fix:
the role chip on the intro card (name + title reads fine under the new
headline), and the web fork's lede, which is a different screen.

Chinese follows the glossary (Agent -> 智能体) rather than the mixed-language
phrasing in the request.

* fix(runtimes): let the member pick the runtime before Mika is created

"Start with Mika" provisioned immediately on
`runtimes.find(online) ?? runtimes[0]`. One machine commonly registers every
agent CLI installed on it — nine on the box this was reported from — so "the
first online one" is an arbitrary pick, and Mika could end up bound to a CLI
the member never intended to run their Chief of Staff on. Rebinding after the
fact is more work than choosing up front.

The action now opens a dialog with the same two controls onboarding already
uses for this decision, RuntimePicker and ModelDropdown, so the same choice
reached from a different entry point is asked the same way. The old heuristic
survives only as the dialog's initial selection, which makes it visible and
changeable instead of silent.

Model resets when the runtime changes, because models are per-runtime and a
value picked for the previous one may not exist on the next.

Co-authored-by: multica-agent <[email protected]>

* refactor(runtimes): one component for "which runtime should Mika use"

Three surfaces asked this same question and had drifted apart: desktop
onboarding and the Runtimes page offered a runtime plus a model, while the
web CLI dialog offered only a runtime. `step-platform-fork` called
`onNext(picker.selected)` with no second argument, so connecting through the
web terminal path silently created Mika on whatever model the runtime
defaulted to, while the desktop step let you choose. Two of the three also
re-implemented "changing the runtime clears the model"; the third simply
lacked it.

MikaRuntimeChoice now owns the pair and that reset rule, so no caller can
forget it and the three entry points cannot drift again. The web CLI path
gains model selection, which is the behaviour change here.

`layout` is a prop rather than a single unified presentation because the
difference is real: the CLI dialog lists machines because that is the moment
they appear one at a time after `multica setup`, and a collapsed dropdown
hides exactly the feedback that dialog exists to give. Everything below the
list is identical.

compact-runtime-row moves from onboarding/ to runtimes/ so imports only flow
onboarding -> runtimes rather than both ways.

Creation is deliberately left alone. A and B still funnel through
`handleRuntimeNext`, which also runs saveQuestionnaire, completeOnboarding
and onComplete; the Runtimes page must not do any of that, since that member
is already onboarded. Merging those would leak onboarding completion into a
non-onboarding surface.

The platform-fork test now needs a QueryClientProvider, because the dialog
renders a model dropdown that queries the runtime's model list, and its
onNext assertion moves to the two-argument signature.

* fix(onboarding): stop the download card claiming a result it cannot know

Clicking "Use this computer" set `downloaded` unconditionally, which flipped
the card to "Opening the download page..." / "Opened in a new tab." Neither
is knowable: `window.open` is called with `noopener`, and per spec that
returns null whether the tab opened or a popup blocker ate it, so a blocked
click still produced a card asserting a tab had opened.

The same flag was also write-once, so the transient "Opening..." became a
terminal state — come back to the tab later and it still says the page is
opening. And because the swapped title wraps to two lines, the card grew
10px and pushed the two cards under it down, which is what made the click
read as a page refresh in the first report.

The card now states its intent up front — "Opens in a new tab — pick your
platform there" — which is true before the click, after it, and when the
popup never appears. The state, both `_after` strings and `hint_downloaded`
are gone from all four locales.

Its test asserted the flip, so it now asserts the opposite: the mocked
window.open returns null (the blocked case) and the card must be unchanged.
Measured after the change: primary card 330px before and after, and the
cards below it do not move.

* fix(desktop): stop one worktree in a thousand booting into a blank window (#6436)

Worktree renderer ports are `5174 + cksum(path) % 1000`, a 5174-6173 window
that contains exactly one port Chromium refuses to navigate to: 6000, the X11
port on its restricted list. A worktree whose path hashes to offset 826 gets a
healthy Vite server on 6000 and an Electron window that fails the load with
ERR_UNSAFE_PORT -- so it reads as a renderer bug, not a port one, and the only
way out was setting DESKTOP_RENDERER_PORT by hand.

Restricted ports in the window are now remapped into the block immediately
above it (6000 -> 6174). Sending them past the end rather than shifting them by
one keeps the offset -> port mapping injective, so two worktrees still cannot
land on the same port and race for it.

* fix(onboarding): close the Mika multi-member and failure-recovery gaps

From Emacs's review of #6378. All seven findings reproduced.

The two blocking server bugs were the same shape: Mika is one agent per
workspace but sessions and ownership are per member.

- StartMikaOnboarding required the agent owner, so the member who lost
  the CreateMikaAgent race — the race that handler's advisory lock exists
  to survive — got a valid Mika, opened a valid session, and then a 403.
  Mika is created workspace-visible and workspace-invocable; the session
  gate and canInvokeAgent were already the checks that matter.
- The onboarding session was resolved client-side by listing sessions and
  creating one on a miss, matched on the localized title.
  LockWorkspaceForChatSessionCreate is FOR KEY SHARE precisely so
  concurrent creators do not block, so two tabs each opened their own
  conversation with its own kickoff, and switching language between a
  failed attempt and its retry opened another. It is now get-or-create
  server-side under a per-(workspace, member) advisory lock, keyed on
  (workspace, creator, agent), returned alongside the agent.

Also:

- The skipped-runtime welcome dismissed itself silently when provisioning
  the guide issue failed. The signal is not persisted and onboarding is
  already complete, so a blip was terminal. It now offers a retry.
- The Runtimes recovery card gated on `agents.length === 0`, so creating
  any ordinary agent hid the only surface that can mint a Mika — the
  generic endpoint accepts no system_key. Gated on Mika's absence.
- CompactRuntimeRow ignored `disabled`; the CLI dialog was already
  passing it, so the runtime could change mid-submit. It is a real
  <button> now, which also gets focus and Enter/Space for free.
- The rail never went below 15rem while the content pane kept its gutter,
  leaving ~87px of form at 375px. It is hidden under md, where a compact
  bar carries the step name and the Back button instead.
- Dropped a stray __pycache__ artifact I had committed by accident.

Each new test was checked against the bug it covers: reinstating the
owner gate, the title-keyed lookup, or the dropped disabled prop makes
the corresponding test fail.

* fix(onboarding): make the Mika entrypoint survive a partial bootstrap

From Emacs's second review of #6378.

Bootstrapping Mika is three server steps — provision the agent, open the
member's session, enqueue the opening turn — and the last two can fail
after the agent commits. Two things then conspired: the server reported
success with the session omitted, and the Runtimes card gated on the
agent existing. The agent's own `agent:created` broadcast invalidates the
agent list, so the card (and its open dialog) was torn down the instant
step one succeeded, and never came back on reload — the agent is durable,
the rest was not. The member was left holding a Mika they could not start.

- The endpoint now fails when the session cannot be resolved. Every step
  is idempotent, so a retry converges; handing back a half-built flow the
  caller cannot distinguish from a finished one does not.
- The entrypoint is gated on the member's own state — does this member
  have a Mika conversation that was actually kicked off — rather than on
  the workspace having an agent. That is the question the card answers,
  and it is true again for every partial state above.

Also restores the Log out escape hatch below `md`. Hiding the rail last
round took its footer with it, which stranded every step but Welcome with
no way out on a narrow screen; the compact bar now renders the same slot,
so `sidebarFooter` is `chromeFooter`.

Each new test was checked against its bug: the old agent-only gate fails
three of the memberNeedsMikaSetup cases, and dropping the footer prop
fails the chrome test.

Bohan Jiang c896f677d5 fix(agent): recover from a codex resume that overflows the reader (MUL-5722) (#6420)
Layer 1 (#6383) raised the shared scanner cap to 32 MiB, which moved the cliff
without removing it — a codex rollout is append-only, so a thread that outgrows
any fixed cap still fails its resume forever. This adds the recovery path.

Layer 2: an oversized thread/resume response is reported as
Result.ResumeRejected rather than a crash, which is the positive evidence
shouldRetryWithFreshSession needs and reconnects the recovery #5715 had
unintentionally cut off. Reaching it required one real fix — the reader wrapped
the scanner error with %v, so bufio.ErrTooLong never survived to a caller.

Layer 3: a new codex_resume_oversized reason marks the session resume-unsafe,
and both resume lookups block by TIME rather than by matching the failed row.
That shape is required, not stylistic: the failure happens before the turn
starts, so the row lands with session_id NULL and is dropped by
latest_per_session before any error-text filter runs. The block expires once a
thread terminates after the overflow, so an issue recovers instead of starting
cold forever.

Also splits the MUL-4424 continuity notice by what each surface can still read
— issue comments and Slack channel history can be re-read, web chat and Feishu
cannot — so only the last group tells the user a loss happened. The backend no
longer holds any of that wording; it receives ExecOptions.ResumeContinuityNotice
from the caller and stays silent when the prompt already carries it, which makes
the duplicate injection on the retry path structurally impossible.

Known gap, tracked not claimed: for chat, the claim handler reads
chat_session.session_id before the fallback query, so a daemon predating this
PR leaves that pointer naming the oversized thread. Clearing it needs the
attempted session recorded at claim time, which is a schema change.

Bohan Jiangandmultica-agent eea687d461 MUL-5686: fix(chat): resume the cancelled turn's session instead of starting cold (#6352)
* fix(chat): resume the cancelled turn's session instead of starting cold

Stopping a chat turn the agent had already begun answering, then sending
the next message, produced a reply with no memory of the conversation.

The cancelled turn's provider session is real and recorded — the daemon
pins it onto the task row mid-flight and cancellation keeps it there —
but nothing could hand it back:

  - GetLastChatTaskSession / GetLastTaskSession only considered
    'completed' and 'failed' rows, so a cancelled row's session was
    invisible to resume resolution;
  - chat_session.session_id is written only by CompleteTask / FailTask,
    and a cancelled task reaches neither: the daemon discards its result
    and sends a cancel-ack. On a chat whose first turn was cancelled the
    pointer therefore stayed NULL and the next turn started cold, since
    buildChatPrompt injects only the current user message.

Let cancelled rows into both resume lookups, and advance the chat-level
pointer at cancel time so a provider that mints a new session id per
resume does not rewind past the cancelled exchange. The mid-flight pin
may now also fill an EMPTY session slot on a just-cancelled row, which
is what a Codex pin waiting on its rollout needs when the cancel wins
the race; occupied slots and completed/failed rows stay untouchable.

Retired sessions, poisoned-failure filters and the rollout-present guard
are unchanged. A transcript killed mid-tool-call that the provider later
refuses is still caught by taskfailure.UnresumableHistory, which retires
the session and starts the next turn fresh.

Fixes #6340

* fix(chat): close the two cancel/pin races on the chat resume pointer

Review found the pointer advance had the same shape of hole it was meant
to fix, on both sides of the cancel.

1. The status flip and the pointer advance were separate statements. In
   the gap the row is already `cancelled` while the pointer still names
   the PREVIOUS turn, so a follow-up the user had queued could be claimed
   there and resume the older session — and a failed pointer write only
   logged, still reporting the cancel as successful. Both now commit in
   one transaction and the error propagates.

2. The mid-flight pin may land AFTER the cancel (for Codex it waits for
   the rollout), so the cancel transaction sees no session to publish and
   the pin only fills the task row. On a chat that already had history
   the stale pointer kept shadowing it, which is precisely the case the
   pin change was added for.

Both paths now run one guarded statement,
AdvanceCancelledChatSessionPointer. It reads the task row itself rather
than trusting an in-memory copy, ignores anything that is not a cancelled
chat task, and refuses to move the pointer when a NEWER task on the chat
already recorded a session — so a straggler pin cannot drag the
conversation back onto the interrupted turn.

Regression tests, both failing before this commit: a cancel whose pointer
write is blocked must not expose `cancelled` to another connection, and a
late pin on an already-cancelled row must reach the next real claim. The
newer-turn guard is covered too.

* fix(chat): make the pin atomic and restore the chat->task lock order

Second review round found the remaining half of the same class of bug.

1. PinTaskSession still committed the session onto the task row and
   advanced the chat pointer as two statements, and the pointer failure
   only logged while the endpoint still answered 204. A follow-up claimed
   in that window resumes the previous turn — the exact case the pin
   change was added for. Both writes now share one transaction and every
   failure is reported.

2. Adding the pointer write gave the cancel transaction two rows to hold,
   and it took them in the wrong order: agent_task_queue first, then
   chat_session. DeleteChatSession takes them the other way round, so the
   two could deadlock (40P01, and runInTx has no deadlock retry). The
   repo's documented order is chat_session -> agent_task_queue; both the
   cancel and the pin now open with LockChatSessionForTask, the same
   helper FinalizeDeferredCancelledChat uses. ErrNoRows there means a
   non-chat task or an already-deleted session — nothing to lock and
   nothing to advance.

Regression tests, all three failing before this commit (the concurrency
one with a real `deadlock detected`): the pin must not expose a session
on the task row while its pointer write is blocked; a cancel waiting on
the chat session must hold no lock on the task row (FOR UPDATE NOWAIT
probe); and cancel racing a chat delete must never come back with 40P01.

Co-authored-by: multica-agent <[email protected]>

* fix(chat): put every chat-task terminal write behind the same lock order

The cancel and pin paths took chat_session before agent_task_queue; the
terminal reports still took them the other way round, so the two could
deadlock (40P01) — reproduced deterministically as cancel-vs-complete.
Choosing per-path was never going to work: either every writer that holds
both rows agrees on an order or none of them are safe.

CompleteTask, FailTask and the cancelled-chat finalize now open with the
same LockChatSessionForTask the cancel, pin, DeleteChatSession and
FinalizeDeferredCancelledChat paths use, via a shared helper that
documents the invariant in one place.

Also de-flakes the concurrency tests this PR added. They held a row lock
and then read other rows on a FRESH pooled connection; the suite shares
one database, so a sibling package's DDL could queue an ACCESS EXCLUSIVE
request in between, park our later ACCESS SHARE request behind it, and
wedge the package until the 10-minute timeout (observed in a parallel
`go test ./internal/...` run). Those transactions now take their table
locks up front and read on the connection that already holds them, and
every racing call is bounded so a stall fails loudly instead of hanging.

Regression tests, all failing before this commit: complete and fail must
hold no lock on the task row while waiting for the chat session (FOR
UPDATE NOWAIT probe), and cancel-vs-complete plus pin-vs-fail must never
come back with 40P01.

* test(chat): fail the race tests on any unexpected error, bound every call

Review nits on the concurrency tests.

Matching only *pgconn.PgError(40P01) let the pin side through: a pin that
loses a deadlock is reported by the HTTP handler as a plain 500 with no
PgError to unwrap, so the check skipped exactly the failure the test
exists for. Both racers now fail on anything except the one benign
outcome — whoever finalized the task first leaves the loser matching no
row (pgx.ErrNoRows).

The remaining racing calls still used an unbounded context.Background(),
which this PR had already claimed were bounded. They now share the same
raceTimeout as the rest.

b06af2ae17 feat(runtime): unbind agents on runtime delete instead of destroying them (#6220)
* feat(runtime): unbind agents on runtime delete instead of destroying them

Deleting a runtime archived its agents and then hard-deleted the rows, so the
agents and every conversation with them disappeared — while the confirmation
dialog said "archive", which a user reasonably reads as recoverable. Retiring a
laptop is an ordinary action; losing the agents configured on it is not an
ordinary consequence.

An agent is now a persistent business object and a runtime is replaceable
execution capacity: deleting a runtime unbinds its agents. `runtime_id IS NULL`
means unbound — orthogonal to archived — and the agent keeps its instructions,
skills, chats, labels, channel installations, autopilots and task history.
service.AgentReadiness already refused an agent with no runtime, so the
scheduling safety gate needed no change.

Two columns become nullable, not one. Without `agent_task_queue.runtime_id`,
deleting the runtime still cascades the task history away (and task_message /
task_usage / task_token with it), so the agents would survive with no record of
anything they did — the same class of loss. A NOT VALID CHECK keeps NULL confined
to history: an active task must always have a runtime, so claim / dispatch /
delivery-CAS paths can never observe one without. It is written against
completed_at rather than a status list so a future non-terminal status fails
closed instead of slipping through.

Two prerequisites this depends on:

- 'deferred' (migration 128) was missing from CancelAgentTasksByRuntimeOrAgent.
  It went unnoticed because the delete used to cascade those rows away; with the
  new CHECK it would abort the delete and make the runtime undeletable.
- The channel-installation / label / chat-pin / invocation-target / draft-restore
  cleanups were scoped to "archived agents on this runtime". Archived user agents
  now survive, so that scope is narrowed to kind='system' — otherwise the fix
  would produce a subtler loss: agent alive, configuration wiped.

Also removes the squad guard that refused (409) when an active squad's leader was
an archived agent on the runtime, plus the archived-squad delete that existed
only to get past squad.leader_id's RESTRICT FK. The leader is no longer deleted,
so nothing needs to be given up to retire a machine. Autopilots are no longer
paused either: their assignee survives, and a rebind restores them without the
owner having to remember to re-enable.

Reason codes: an unbound agent reports agent_runtime_required, not
runtime_offline. The copy for runtime_offline tells users to reconnect a machine;
an unbound agent has no machine to reconnect, and the fix is to bind a runtime.
Chat's bare 409 string gains the same code so the composer can offer that action.

API: agents gain runtime_bound. runtime_id stays a string (empty when unbound) so
installed clients keep parsing and no gated two-release rollout is needed. The
confirmed-delete endpoint is /unbind-agents-and-delete; /archive-agents-and-delete
still routes to it, and the compared expected_active_agent_ids set is unchanged —
widening it would 409 every older client forever.

* feat(chat): add agent-generated quick actions

Co-authored-by: multica-agent <[email protected]>

* fix(chat): preserve mid-response quick-action fences

Co-authored-by: multica-agent <[email protected]>

* fix(chat): drop quick actions on empty reply to keep no_response fallback

An actions-only completion — a quick-actions footer with no visible text —
wrote an empty-content assistant message (message_kind=message). Older
Desktop/mobile clients ignore the quick_actions field and render that as an
empty bubble, breaking the MUL-4351 contract that an empty turn always gives
old clients a visible no_response fallback.

Drop the quick actions when the visible body is empty so an actions-only turn
falls through to the visible no_response outcome, and revert the completion
switch to gate the message row on visible text only. Update the completion
test to pin the corrected behavior.

* feat(chat): generate quick actions via daemon suggestion pass

Replace the in-band runtime-brief instruction with a dedicated post-completion
provider turn: after a direct chat reply finishes, the daemon resumes the same
session with a JSON-only suggest prompt and forwards the raw output on the
complete callback. The server parses it leniently and reuses the existing
sanitize/redact/store/broadcast pipeline; the stripped in-band footer stays as
a fallback for older daemons and pre-upgrade sessions. The footer strip now
covers every chat completion, fixing the intro-turn protocol leak. Adds a
Settings → Chat toggle (client-persisted, default on) that hides the chips.

Co-Authored-By: Claude Fable 5 <[email protected]>

* feat(chat): deliver quick actions async with skeleton placeholders

Decouple suggestion generation from the turn: the daemon reports completion
immediately (chat:done carries quick_actions_pending as a per-turn capability
signal) and runs the suggestion pass in the background, delivering results
through a new supplement endpoint + chat:quick_actions broadcast. A new turn
on the same session cancels the stale pass. Clients render pill skeletons
under the finished reply until the supplement resolves them (entrance
animation on arrival, 30s safety timeout); older daemons never raise the flag
so no skeleton dangles. Suggest usage re-reports merged totals because
task_usage upserts replace per (task, provider, model). Prompt now asks for
exactly 3 actions.

Co-Authored-By: Claude Fable 5 <[email protected]>

* feat(chat): make the quick-actions toggle stop generation, not hide pills

The Settings → Chat toggle previously only hid rendered pills while the
daemon kept burning a suggestion call every turn. It now travels with each
send (quick_actions_enabled, absent = enabled for older clients), is stamped
on the chat task (migration 213), forwarded on the claim, and gates the
daemon's suggestion pass at the source — no call, no pending flag, no
skeleton. Existing suggestions stay visible; settings copy now says
'generate' instead of 'show'.

* fix(migrations): renumber quick-action migrations onto current main

Merging current origin/main brought the vcs migrations to their canonical
216-221 prefixes, which collided with the quick-action migrations that were
sitting at 219/220 (backend CI red in
TestMigrationNumericPrefixesStayUniqueAfterLegacySet). Renumber them to the
next unused prefixes:

- 219_chat_message_quick_actions        -> 222_chat_message_quick_actions
- 220_agent_task_quick_actions_disabled -> 223_agent_task_quick_actions_disabled

Contents are unchanged; sqlc regeneration produces no drift since the added
columns are independent of the vcs tables.

* fix(mobile): render async chat quick actions via chat:quick_actions

The daemon generates quick actions in a background pass after the turn
finishes, delivering them on a separate chat:quick_actions event. Mobile
only handled chat:done (which invalidates + refetches an actions-less
message list) and keeps the messages query at staleTime: Infinity, so an
active mobile session never rendered async-generated quick actions until a
manual pull-to-refresh or refocus.

Add applyChatQuickActionsToCache — mirroring web's patcher — which patches
the supplement onto the targeted assistant message in the flat messages
cache, and subscribe to chat:quick_actions in use-chat-session-realtime.
Patch-only (no invalidate), matching web and mobile's cellular
patch-over-invalidate rule; an empty supplement is a terminal no-op. Covered
by chat-ws-updaters.test.ts.

Co-Authored-By: Claude Opus 4.8 <[email protected]>
Co-authored-by: multica-agent <[email protected]>

* fix(chat): cancel in-flight messages refetch before quick-actions patch

The chat:done invalidate can leave a messages refetch in flight that read the
assistant row before the daemon persisted the quick actions. If that refetch
resolves after the chat:quick_actions setQueryData patch, it overwrites the
freshly-patched actions with an actions-less row. Both message caches are
staleTime: Infinity, so the overwrite never self-heals and the actions vanish
permanently (MUL-5149, Howard review).

applyChatQuickActionsToCache now awaits cancelQueries for the affected caches
(web: flat messages + messagesPage, mobile: flat messages) before patching, so
a stale in-flight refetch is cancelled and cannot land after the patch. Cancel
must precede setQueryData because cancelQueries reverts to the pre-fetch state.
WS handlers call it via `void` (fire-and-forget).

Adds an active-query race regression test on both web and mobile that holds a
refetch open across the supplement and asserts the patched actions survive;
verified to fail without the cancel.

* feat(chat): quick-actions refresh/regenerate + review hardening (MUL-5149)

Co-authored-by: multica-agent <[email protected]>

* fix(chat): address quick-actions re-review (MUL-5149)

- Ack alignment: refresh request carries the target message_id; server
  atomically confirms it is still the session's latest turn (409 stale
  otherwise), so the client marker always matches the resolving
  chat:quick_actions — no response reconciliation. Adds a regression test.
- Converge the pending marker on every terminal path: HandleFailedTasks
  (sweeper/orphan) now resolves it, and the daemon reports a failed supplement
  so FailTask resolves it instead of leaving a completed-but-unresolved task.
- Timeout fallback now clears the real query state (useQuickActionsPendingTimeout)
  instead of a component-local flag that only masked the UI; drop the skeleton's
  and pill row's local timers.
- frontend-test type-scale: text-xs -> text-caption. Strip EOF blank line.

Co-authored-by: multica-agent <[email protected]>

* fix(chat): close quick-actions refresh races and failure feedback (MUL-5149)

Third-round review of the refresh button surfaced three issues; all three
are addressed here.

§1/§2 Session-busy race + concurrent-refresh double-spend: a newer reply
that is queued/running but whose assistant row hasn't landed leaves the old
turn as latest-persisted, so the stale check passes and the regen resumes
the newer provider state — attaching suggestions to the wrong turn. And two
concurrent refreshes each enqueue a quota-spending pass. Add
HasActiveChatTaskForSession and refuse a refresh (ErrChatQuickActionsBusy →
409) whenever the session has any task in flight, checked under the same
session lock as the enqueue so no sibling insert slips past.

§3a Timeout re-arm on surface switch: the pending marker now carries an
absolute expires_at deadline instead of a per-mount timer, so switching
between the floating window and the chat tab resumes the same deadline
rather than restarting a fresh 30s window each remount.

§3b Generation failure masked as success: runChatSuggestPass now returns ok
so an explicit refresh distinguishes a failed pass (didn't start / didn't
complete / timed out) from a completed-but-empty one. On failure the regen
task reports failure, resolveFailedRegenerateQuickActions broadcasts a
FAILED chat:quick_actions, and the client resolves the spinner AND toasts
"couldn't refresh" instead of silently stopping on unchanged pills.

Co-authored-by: multica-agent <[email protected]>

* fix(chat): count deferred tasks in refresh busy check; solid refresh icon tone (MUL-5149)

Two re-review blockers on 2dc9404d.

§1 (deferred window): HasActiveChatTaskForSession only treated
queued/dispatched/running/waiting_local_directory as in-flight, so a chat
auto-retry armed with a backoff fire_at — inserted 'deferred' by
CreateRetryTask, as provider_network's ~5s final attempt is — slipped past
the busy check. In that window the failed turn has no assistant row yet, so
the old turn is still latest-persisted and refreshable; the regen would then
resume a session the retry is about to advance and pin the new turn's
suggestions onto the old one. Add 'deferred' so the set matches the
canonical in-flight status list the rest of the queries already use
(agent.sql has-active-task checks). New regression test covers a deferred
active turn.

CI (text-contrast gate): the refresh icon button used
text-muted-foreground/70 (transparency standing in for a text tone), which
the frontend-test contrast gate rejects. Switch to the solid
text-faint-foreground token — the tone the gate recommends for icons/glyphs,
already used repo-wide and clearing WCAG 1.4.11.

Co-authored-by: multica-agent <[email protected]>

* test(chat): assert quick-actions pending marker carries expires_at (MUL-5149)

The chat:done supplement-flow test still expected the 2-field marker from
before the absolute-deadline change; applyChatDoneToCache now stamps
expires_at, so the deep-equal failed on frontend-test. Assert the deadline is
present (expect.any(Number)) rather than a wall-clock-dependent value — its
timing semantics are covered by the pending-timeout hook.

* fix(db): renumber regenerate-quick-actions migration 237 -> 240 (MUL-5149)

main merged Issue Quick Actions (MUL-5465) taking migrations 237/238/239
(quick_action, quick_action_workspace_index, comment_quick_action). This
branch independently took 237 for agent_task_queue.regenerate_quick_actions_for.
The two 237s do not textually conflict (different filenames) so the PR reads
mergeable, but the merged tree would carry two migration 237s. Renumber this
one to 240 so it applies after main's chain. The migration is a standalone
`ALTER TABLE agent_task_queue ADD COLUMN IF NOT EXISTS` — order-independent,
touches a column none of main's migrations reference.

30318b79bc MUL-5426: fix(daemon): retire sessions whose history the provider refuses to replay (#6083)
* fix(daemon): retire sessions whose history the provider refuses to replay

A run killed mid-reply (machine shutdown, force-quit, SIGKILL) can leave an
empty assistant message in the agent CLI's transcript. Every later resume
replays it, the provider rejects the request, and the (agent, issue) pair is
bricked with no self-healing and no user-facing recovery.

Multica already has the mechanism for this — poisoned-session classification —
but its detector paired "400" with "invalid_request_error", which is the
Anthropic wire shape. The same defect reported by any other provider carried
neither token, so it classified as agent_error.unknown: resume-safe by
omission. GetLastTaskSession kept handing back the dead session on every
follow-up, manual Rerun resolved it through the same predicate, and the
in-turn fresh-session retry never fired because ResumeRejected is false here
(nothing rejected the resume — the transcript loaded and the provider refused
to replay it).

Add taskfailure.UnresumableHistory, which recognises the defect by what the
provider says is wrong — some content is empty, and here is which message in
the history — rather than by status code or provider name. Both signals are
required, so a tool reporting "field must not be empty" does not match.

Wire it into the four places that decide whether a session survives:

- classifyPoisonedError, so the task is written as api_invalid_request
- shouldRetryWithFreshSession, so the turn recovers on all 17 backends
  instead of the subset whose adapter learned to detect it; the tools == 0
  gate is unchanged, so a run that already used a tool is never re-run
- ResumeUnsafeFailure, covering the manual-Rerun path
- both resume queries, as defense-in-depth for hosts whose daemon predates
  this (self-host daemons upgrade on their own cadence)

Fixes #6066. Also covers the daemon half of #5760.

Co-authored-by: multica-agent <[email protected]>

* fix(session): close the Chat and fresh-retry paths that resurrect a poisoned session

Review found the previous commit stopped short in two places, both of which
put the dead transcript back in play.

Chat never consulted the guarded query. The claim handler reads
chat_session.session_id first and only falls back to GetLastChatTaskSession
when it is empty, so a poisoned pointer there bypasses every filter that query
applies. The fail path merely declined to OVERWRITE the pointer, leaving it in
place. It now clears it in the same transaction, matched on session and
runtime so a concurrent turn's newer pointer survives. The promote guard moves
to ResumeUnsafeFailure as well — the reason-only check passed an un-upgraded
daemon's agent_error.unknown row and re-pinned what the clear had just removed.

GetLastChatTaskSession also kept the row-level filter the issue query dropped
in GH #5975: it discarded the newest poisoned row and fell back to an older
completed row carrying the same dead session. It now judges each session by
its latest terminal state, matching GetLastTaskSession.

A recovered turn could not retire anything. A terminal report carried one
session_id, and an empty one meant both "nothing to report" and "forget the
old session", so a fresh-session retry that SUCCEEDED left the id it retried
away from selectable — through an older completed row on the issue, or through
the chat pointer. agent_task_queue.retired_session_id records the abandonment
itself, reported on every terminal path including completed, and both resume
lookups exclude it. This is the contract gap the previous PR deferred; the
fresh-retry path now runs on all backends, so deferring it is not safe.

Also narrows what the cross-backend test claims: it pins the shared decision,
not that all 17 adapters surface the error into Result.Error (#5760 is the
counter-example), and says so.

Co-authored-by: multica-agent <[email protected]>

* test(session): require pgx.ErrNoRows in the resume-exclusion assertions

The `if err == nil && prior.SessionID.Valid` form these tests shared is
false-green: any real fault — undefined column, syntax error, dead connection
— makes err non-nil, so the condition is false and the test passes. Run
against a database missing this branch's new column, the exclusion tests
reported PASS on a SQLSTATE 42703, meaning they could not have caught a broken
query.

requireSessionExcluded demands pgx.ErrNoRows specifically and fails loudly on
anything else, so a green run now means the filter worked rather than the
query never ran.

Applied to all nine sites, not just the four this branch added: the other five
guard the same GetLastTaskSession exclusion behaviour that this branch
changes, so leaving them false-green would leave the change under-tested. All
nine pass on a correctly migrated database.

d4dac0e77c perf(agents): index-backed latest-terminal lookup in task snapshot (MUL-5436) (#6085)
ListWorkspaceAgentTaskSnapshot took each agent's latest completed/failed
task with a workspace-wide DISTINCT ON, so every presence load read and
sorted the workspace's whole terminal history. Neither existing index
matches that shape: (agent_id, status) has no completed_at, and migration
231's (completed_at) partial index is completed_at-first for the Usage
rollups.

Replace the outcome half with a per-agent JOIN LATERAL Top-1 and add a
partial index on (agent_id, completed_at DESC NULLS LAST, created_at DESC,
id DESC) WHERE status IN ('completed','failed'). On a 40-agent workspace
with 200k terminal rows this goes from 6631 shared buffers / 48.3 ms to
162 buffers / 0.1 ms, with an identical row set.

The (created_at, id) tie-break also makes the pick deterministic when
completed_at ties or is NULL — completed_at DESC alone left the winner up
to the plan.

Report #6075 asked to delete the outcome half as dead code, but PR #2608
made the Squad hover card (AgentLivePeekCard) read those rows for its
"last activity" line, so removing them would be a product regression for
shipped desktop builds. The response contract is unchanged here; splitting
the outcome into a lazy endpoint stays follow-up work.

Also tighten pickLatestTerminal to completed/failed only, matching the
snapshot's filter — it accepted cancelled, which the endpoint never
returns and which would have masked an agent's last real outcome.

2e9a3d0119 fix(dashboard): stop leaking private agents from the per-agent rollups (MUL-5409) (#6051)
* fix(dashboard): stop leaking private agents from the per-agent rollups (MUL-5409)

Three per-agent dashboard endpoints authorized on workspace membership alone
and returned a bare agent_id for every agent in the workspace:

  GET /api/dashboard/usage/by-agent
  GET /api/dashboard/agent-runtime
  GET /api/dashboard/failures/by-agent

That told a plain member which private agents exist, how much they spend, how
long they run and what they fail on. The client already collapsed those rows,
but client-side filtering is decoration — one curl bypasses it.

Server: rows for agents the caller may not view are now folded onto a
`__restricted_agents__` sentinel before serialization, via one shared helper.
Folded, not dropped: each of these responses is the per-agent half of a pair
whose other half (usage/daily, runtime/daily, failures/daily) is workspace-
scoped and unfiltered, so dropping rows would make the per-agent breakdown stop
adding up to the KPIs rendered beside it. The bucket keeps its provider/model
and failure_reason dimensions — both are derivable by subtraction from the
workspace-level series anyway, and the client needs them to price the bucket and
compute its failure rate.

Owner/admin and agent actors short-circuit before any extra query, so the
governance view is unchanged. Hard-deleted agents are deliberately excluded from
the fold — they have no visibility left to protect and keep their own bucket.

Client: fixes the mislabelling that shipped with this. A live private agent was
folded into a row labelled "Deleted agents" with a bin icon, and counted into
the card's "· N deleted" caption — telling the user N agents were deleted when
they are alive and still running. The restricted bucket is now its own row with
neutral copy, keeps its real Time / Tasks values, and counts as neither an agent
nor a deletion in the caption.

Tests: handler regression coverage proving a plain member's response contains no
private agent UUID while every aggregate still sums to the privileged view's
total, plus view coverage for the label and caption.

* fix(dashboard): fold hidden system agent carriers into the restricted bucket (MUL-5409)

Review follow-up. The first pass built the restricted set from ListAllAgents,
which filters `kind = 'user'` — so it missed the hidden `kind = 'system'`
execution carriers behind agent-builder sessions.

Those carriers run real tasks and book real usage, and all three rollups
aggregate over agent_task_queue / task_usage with no kind filter of their own.
No list endpoint returns them either (ListAgents / ListAllAgents both filter on
kind), so no client can resolve one to a name. Net effect: the exact two bugs
this PR exists to fix, still live — a bare UUID exposing one member's builder
session (with its spend and failure profile) to every other member, and, once
the agent list loads, a running agent folded into the client's "Deleted agents"
row and counted as a deletion.

restrictedAgentIDs now reads a new ListAllAgentsAnyKind and restricts every
non-user-kind agent for EVERYONE, workspace owner included — nobody can name
one, so a bare UUID row is wrong for every viewer, not just plain members. User
agents keep the per-viewer visibility rule. The invocation-target lookup is
skipped for actors that rule can never restrict (agent actors, owner/admin), so
the added cost is one indexed list query.

Because the bucket now also carries carriers that are nobody's "restricted"
agents, its copy drops to the neutral "Other agents" — the same wording the
Errors card already uses for its equivalent row, in all four locales.

Adds a regression test seeding a kind=system private carrier with tasks and
usage: no endpoint may return its UUID to either the plain member OR the
workspace owner who owns it, a bucket must be present to carry its rows, and
every metric delta (tokens, seconds, tasks, failures, runs) must equal its exact
contribution. Verified to fail on all three endpoints for both viewers with the
kind-filtered query restored.

2274f521dc feat(issues): agents-working chip on the sub-issues header (#5825) (#5834)
* feat(issues): aggregate agents-working chip on the sub-issues header (#5825)

Add a live "N agents working" chip next to the sub-issues progress ring
in issue detail. The per-row IssueAgentActivityIndicator shows which
sub-issue is being worked; this chip shows how many agents are on the
parent's children at a glance — and keeps that signal visible while the
list is collapsed.

Derives from the shared workspace agent-task snapshot narrowed by a new
selectIssuesTasks select (structural sharing keeps unrelated snapshot
churn from re-rendering the header). Counts unique agents to match the
workspace chip, whose chip_agents_working / hover_header_queued strings
it reuses — already translated in every locale. Hover opens the shared
AgentActivityHoverContent task list.

Fixes #5825

Co-authored-by: multica-agent <[email protected]>

* refactor(issues): read the sub-issues chip from the working-agents projection (#5825)

The chip landed deriving its own count from the workspace agent-task
snapshot, which put a second definition of "an agent is working" in the
client. It showed up immediately: the number came from the running tasks
only while the hover body listed running plus queued, so a parent with 2
running and 3 queued agents read "2 agents working" over a five-row card.

A header count is a claim about a scope, so let the server own both the
scope and the arithmetic, exactly as the Issues list header already does.
ListWorkspaceWorkingAgents grows an optional parent_issue_id narrowing and
the chip reads /api/working-agents?type=issue&parent=<id>. The number, the
avatars and the hover body are now one list rather than three derivations,
so they cannot disagree.

Row indicators keep reading the snapshot. One shared query sliced per row
is the right shape for a per-row cue and a stale row decoration costs
nothing; a header number is the opposite, it has to be authoritative.

The new parameter is additive: omitted, the query and the response are
byte-for-byte what they were, so an installed client that never sends it
keeps the workspace-wide behaviour. A regression test pins that.

Bohan Jiang 49fd6cd08a fix(handler,service): return 409/coalesced instead of 500 on duplicate-key violations (MUL-5285) (#5958)
Two unique-constraint violations surfaced as an HTTP 500 with the raw Postgres
constraint name leaked to the caller (#5914).

- UpdateAgent now mirrors CreateAgent: a 23505 / agent_workspace_name_unique
  violation returns a clean 409 instead of a 500 whose body leaked the constraint
  name. The (workspace_id, name) constraint does not exclude archived agents, so
  renaming into a name still held by an archived agent hit exactly this path.
- The mention enqueue detects the idx_one_pending_task_per_issue_agent violation,
  returns a bare typed sentinel (no driver text), and logs the benign race at
  debug instead of error.

Review then hardened the same duplicate-enqueue path so it never reports an
outcome it cannot back: coalesced only after an atomic head-scoped merge,
deferred only when an active task's reconcile will replay the comment, queued
only after a fresh enqueue, and an honest internal_error otherwise. Head scoping
(TEN-356) is preserved throughout, planned-id registration excludes queued tasks
so re-attribution stays atomic (MUL-4302), and a blocked completion replay is
handed on rather than discarded.

One shape remains best-effort — a different-head queued blocker can neither cover
the comment nor accept it without violating TEN-356 — and is logged at error;
that drop predates this change. Tracked in #5985.

No migration, foreign key, or cascade.

85a14cde37 fix(daemon): gate codex session pointer writes on rollout presence (MUL-5305) (#5960)
* fix(daemon): gate codex session pointer writes on rollout presence (MUL-5305)

Codex issue follow-ups on local_directory projects intermittently lost
their session: the server sent a prior session whose rollout was not in
the task CODEX_HOME, so the daemon dropped the resume and started a fresh
thread (gateCodexResumeToRolloutPresence), losing the conversation.

Root of the bad pointer: the daemon persists a Codex session id as the
resumable pointer at two points -- the mid-flight pin and the terminal
report -- before the rollout is guaranteed on disk. A task that exits
early (crash / runtime offline / timeout) leaves a pinned/reported
session id with no rollout; GetLastTaskSession (which accepts failed
rows) then hands it to the next follow-up, which drops it.

Enforce the invariant at write time: only record a Codex session as the
resumable pointer once its rollout is present in the per-issue store,
with a short bounded wait for flush. If it never lands, don't overwrite
the last good pointer -- a blanked session_id becomes NULL server-side,
so GetLastTaskSession falls back to the most recent session whose
rollout is real. Non-Codex providers are unaffected; crash recovery is
preserved because a present rollout still pins.

- codexSessionResumable: shared write-time presence check (bounded wait)
- runTask: gate the terminal session_id before reporting
- executeAndDrain: gate the mid-flight pin (thread codexHome through)
- tests: helper cases + behavioral pin test

Co-authored-by: multica-agent <[email protected]>

* fix(daemon): address review — don't silently downgrade completed sessions (MUL-5305)

Follow-up to review feedback on #5960:

- Must-fix 1 (silent downgrade): limit the write-time session withholding
  to NON-completed terminal states. A missing rollout means no resumable
  conversation was persisted, so a withheld non-completed attempt loses
  nothing; a completed session is authoritative and, if its rollout is
  anomalously absent, is still recorded so the next run's resume gate
  discloses the loss (PriorSessionResumeUnavailable, MUL-4424) instead of
  silently falling back to an older session. Extracted
  resumableTerminalSessionID.
- Non-blocking risk: pin the mid-flight resume pointer with a per-status
  presence check instead of one fixed 2s window, and set sessionPinned
  only once the rollout is confirmed, so a rollout that lands shortly
  after the first status is still pinned this run.
- Must-fix 2 (regression coverage): pin skipped when rollout absent (no
  /session call); terminal helper (completed keeps / failed withholds);
  and a DB-backed GetLastTaskSession test proving the next claim falls
  back to the older recorded session when the latest was blanked.

* fix(daemon): disclose Codex session continuity gaps end-to-end (MUL-5305)

Addresses review feedback on #5960.

Must-fix 1 — a completed turn whose rollout is missing is exactly the
#5934 case (the reporter waits for each turn to finish), so it can no
longer be excluded from withholding. Withhold the session for ANY
terminal state, and pair the withhold with a persisted continuity-gap
signal so the next claim still discloses the loss even while resuming an
older good session:
  - new agent_task_queue.session_rollout_missing column (migration 224)
  - daemon sends session_rollout_missing on the terminal report; the
    handler clears the resume pointer (MarkTaskSessionRolloutMissing,
    overriding FailAgentTask's COALESCE) and flags the row
  - claim reads GetLatestTaskRolloutMissing and sets a new
    prior_session_resume_unavailable response field, which the daemon ORs
    into the brief's PriorSessionResumeUnavailable disclosure

Must-fix 2 — Codex reveals the session id on a single task_started
status, so a one-shot presence check missed a rollout that flushed later
and lost in-flight crash recovery. Pin via a background waiter bounded by
the run's context that pins the moment the rollout lands.

Tests: - completed + rollout missing -> next claim withholds the bad session
    AND flags the continuity gap (cross-layer DB test)
  - session pinned once its rollout appears after the status (mid-run)
  - pin skipped while the rollout is absent
Co-authored-by: multica-agent <[email protected]>

* fix(server): make continuity-gap write atomic + disclose on all claim paths (MUL-5305)

Addresses review round 3 of #5960.

Must-fix 1 — the previous handler-level marker ran AFTER the terminal
transaction committed, and FailTask creates + wakes the auto-retry inside
that same transaction, so a retry could claim the rollout-missing session
before the marker cleared it (and a marker failure was swallowed). Move
session_rollout_missing INTO the terminal write: CompleteAgentTask and
FailAgentTask now force session_id NULL (overriding Fail's COALESCE that
would keep a stale mid-flight pin) and set the flag in the SAME UPDATE, so
the withhold + gap flag commit atomically with the retry creation. The
flag is threaded through TaskService.CompleteTask/FailTask; the swallowed
best-effort MarkTaskSessionRolloutMissing query is removed.

Must-fix 2 — the daemon withholds for all Codex tasks, but only the issue
non-rerun claim consumed the disclosure. Now every fallback path sets
prior_session_resume_unavailable: the manual-rerun branch reads the source
task's session_rollout_missing, and the chat branch reads a new
GetLatestChatTaskRolloutMissing.

Tests (cross-layer DB):
- completed + rollout missing via the real CompleteAgentTask terminal
  write -> session withheld AND gap flagged
- failed + rollout missing forces session_id NULL over the COALESCE-
  preserved mid-flight pin in ONE statement

Deploy order: migration + server first, daemon second (new fields are
omitempty and ignored by an old peer).

* fix(handler): return 5xx on FailTask error + cover claim-response gap paths (MUL-5305)

Addresses review round 4 of #5960.

Must-fix 1 — the FailTask handler returned 400 on a service/DB error, but
the daemon's terminal callback treats 400 as permanent (postJSONWithRetry
/ isTransientError bails without retrying). Since the fail transaction is
now the sole persistence point for the withheld session + continuity-gap
flag + auto-retry, a rolled-back fail must be retried, so return 5xx (an
invalid request body still returns 400), mirroring CompleteTask.
Regression: client.FailTask retries on a transient 5xx and eventually
succeeds.

Must-fix 2 — add claim-response-level regressions that drive the two new
disclosure branches through buildClaimedTaskResponse:
  - chat: the latest terminal task on the session withheld -> the next
    chat claim sets prior_session_resume_unavailable
  - manual rerun: the source task withheld -> the rerun claim discloses
These handler DB tests run under CI's fully-migrated database (the local
workspace DB cannot set up the handler fixture).

Bohan Jiang 168620fc15 MUL-5163 fix(agents): rebind the Agent Builder carrier when the runtime is switched (#5780)
Switching the runtime mid-conversation in Build with AI only updated local React state, so the picker could show runtime B while every subsequent message still executed on the runtime frozen at session create time.

- Add PATCH /api/agent-builder/sessions/{id}/runtime to rebind the hidden builder carrier (runtime_id/runtime_mode, model cleared since model ids are per-runtime). Creator-only, builder carriers only, target must be in-workspace, usable by the member, and online; a reply in flight returns 409.
- Serialise rebind against send: both take LockChatSessionForRuntimeBind on the chat_session row and SendDirectChatMessage re-reads the agent inside that transaction, so a send blocked behind a rebind cannot resume and stamp its task with the runtime the switch moved away from.
- Leave chat_session.runtime_id stale on purpose so the daemon starts a fresh provider session on the new runtime while Multica-side history and the draft survive.
- Frontend updates the draft only after the server reports the bound runtime, blocks sending during a rebind, disables the Mine/All filter alongside the trigger, and explains why the picker is locked during a pending reply.

* fix(agents): renumber runtime-skill migration and broadcast agent:status on toggle

Address the MUL-5101 review blockers on PR #5686:

- Rebase onto main and renumber the runtime-skill-disable migration
  202 -> 203. main added 202_runtime_profile_add_qwen, so the pair
  collided on prefix 202 and migrations_lint_test would reject the
  duplicate. 203 is the next free prefix.
- Publish an "agent:status" event after persisting a
  disabled_runtime_skills override, mirroring the workspace-skill toggle
  in writeUpdatedAgentSkills. The realtime layer keys off this event to
  invalidate workspaceKeys.agents, so other open web/desktop/mobile
  clients now drop their stale toggle state instead of only the
  initiating tab refreshing. Reload junction-table skills before the
  broadcast so it doesn't signal cleared skills (#3459).
- Add a handler regression test proving the broadcast fires on both
  disable and enable.

6dba74c3c1 fix(task): auto-retry transient "Connection closed mid-response" like chat (MUL-4910) (#5565)
* fix(task): auto-retry transient provider stream cut like chat (MUL-4910)

Claude Code's "API Error: Connection closed mid-response" is a transient
network cut. In unattended issue runs it fell through to
agent_error.unknown / process_failure — neither in retryableReasons — so
the task terminated. Interactive chat only appeared resilient because the
CLI's own in-process retry usually recovers first; there is no
chat-specific retry in Multica. Both paths share the same
finalizeStreamResult -> Classify -> retryableReasons pipeline.

- classify: route "connection closed" / "mid-response" to
  agent_error.provider_network, before the exit-status rule so the
  "exited with error: exit status N" variant also lands here.
- retry: add provider_network to retryableReasons. It is resume-safe, so
  the retry child inherits the session and continues the truncated
  conversation instead of restarting.

Tests cover the new classification (incl. exit-status variant) and the
retry/resume flags. Note: mirror the substrings into the MUL-1949 offline
backfill SQL to keep in-flight and historical taxonomies aligned.

* feat(task): defer provider_network's final retry ~5s — three-tier (MUL-4910)

Follow-up to the immediate-retry fix: make the connection-closed retry a
three-tier schedule — first run + immediate retry + one retry deferred ~5s —
so a blip that survives the immediate retry gets a short cooldown before the
final attempt instead of firing back-to-back.

Reuses the existing deferred/fire_at primitive (the comment-routing escalation
mechanism) rather than adding new infrastructure: CreateRetryTask gains an
optional fire_at; when set, the child is inserted 'deferred' and the existing
PromoteDueDeferredTasksForRuntime sweeper — already run promote-first on every
claim poll — flips it to 'queued' at fire_at. No migration, no claim-query
change, no daemon change.

- retryAttemptCeiling: raise provider_network's ceiling to 3 (other reasons
  keep max_attempts=2); applied in both retryEligible and
  MaybeRetryFailedTask's budget pre-check so the primary and sweeper paths agree.
- retryDelayForAttempt: only provider_network's final attempt is deferred (5s);
  every other retry — including provider_network's first — stays immediate.
- FailTask + MaybeRetryFailedTask pass fire_at and skip the queued
  broadcast/notify for a deferred child (promotion emits them at fire time).

Timing: the deferred child fires on the first claim poll at/after fire_at, so
>= 5s; on an otherwise-idle runtime it can stretch to the poll interval — the
same behaviour deferred escalations already have.

Tests: pure schedule/eligibility coverage (TestProviderNetworkRetrySchedule)
plus a DB test asserting fire_at controls deferred-vs-queued, attempt=3, and
resume-safety.

Co-authored-by: multica-agent <[email protected]>

* fix(task): persist reason-aware retry budget; respect max_attempts=1 disable (MUL-4910)

Addresses the pre-merge review must-fix: retryAttemptCeiling raised
provider_network to 3 unconditionally, which (1) overrode the
max_attempts=1 "auto-retry disabled" contract and (2) persisted a
self-contradictory child (attempt=3, max_attempts=2) that leaks to the
task API, so a naive attempt < max_attempts consumer would misjudge the
budget.

- retryAttemptCeiling now returns taskMaxAttempts unchanged when it is <= 1
  (disabled stays disabled) and only ever WIDENS otherwise (max(col, 3) for
  provider_network) — a higher configured budget is kept.
- CreateRetryTask takes an optional max_attempts; FailTask and
  MaybeRetryFailedTask write the reason-aware effective ceiling into the
  child so the whole retry chain self-describes (attempt=3, max_attempts=3).
  NULL inherits the parent column, so non-provider_network reasons are
  unchanged.

Tests:
- pure: ceiling widens to 3, keeps a higher budget, and never revives a
  disabled (max_attempts=1) task; eligibility rejects the disabled case.
- DB (end-to-end FailTask): default budget → deferred final child at
  attempt=3/max_attempts=3; first failure → immediate child; max_attempts=1
  → no child. Plus CreateRetryTask persists the passed budget / inherits on NULL.

ae68799c64 feat(task): reuse workdir on manual retry, gate session on error class (MUL-4869) (#5525)
* feat(task): reuse workdir on manual retry, gate session on error class (MUL-4869)

A manual retry (execution-log "retry" button -> POST /api/issues/{id}/rerun)
previously set force_fresh_session=true unconditionally, so the daemon threw
away the failed run's workdir and started from an empty one. For a transient
failure (network blip, provider 5xx / rate-limit, runtime_offline, timeout)
that discards work the agent already did.

New contract: a retry ALWAYS reuses the source task's workdir when it still
exists on disk; only the agent SESSION is gated, on whether the source task's
failure poisoned the conversation.

- RerunIssue derives force_fresh_session from the source task's failure_reason
  via resumeUnsafeFailureReason instead of hardcoding true. Transient/cancelled
  failures resume the session; conversation-poisoning failures start fresh.
- The daemon claim handler resolves the retry's session/workdir precisely from
  rerun_of_task_id, not the most-recent (agent,issue) row that a parallel task
  could hijack. PriorWorkDir is returned whenever present; PriorSessionID only
  when resume-safe AND on the same runtime.
- force_fresh_session now gates only the session, never the workdir.
- Add agent_error.context_overflow to the resume-unsafe set (Go helper plus the
  GetLastTaskSession / GetLastChatTaskSession blacklists): resuming an overflowed
  context would immediately overflow again.

Objectively-unreusable cases (workdir GC'd, different runtime, failed before a
workdir was recorded) fall back to a fresh Prepare via the daemon's existing
execenv.Reuse / gateResumeToReusedWorkdir path, so no daemon change is needed.

Tests: RerunIssue force_fresh classification by failure_reason; claim-layer
workdir-always-reused plus session gating (same/different runtime, poisoned);
context_overflow classifier.

Co-authored-by: multica-agent <[email protected]>

* fix(task): make manual-retry workdir reuse rollback-safe and error-text aware (MUL-4869)

Addresses code review on #5525.

- Rollback safety: RerunIssue no longer writes force_fresh_session based on the
  source failure. Rerun rows are pinned to force_fresh_session=true again, so an
  OLD claim handler picked up mid rolling-deploy degrades to a clean start
  instead of falling back to the (agent, issue) most-recent lookup and resuming
  a *different* execution. The new claim handler ignores the flag for reruns and
  computes session reuse from the exact source task (rerun_of_task_id).

- Legacy poison defense: add shared service.ResumeUnsafeFailure(failureReason,
  errorText), which combines the failure_reason poison set with the same
  400/invalid_request_error raw-error-text guard GetLastTaskSession applies. The
  claim handler's exact-source path uses it, so legacy 'agent_error' /
  deploy-window rows carrying a 400 marker are no longer resumed.

- CI: TestRerunIssueTargetsSourceTaskAgent passes again (rerun rows stay
  force_fresh_session=true). Service test now asserts that rollback-safe
  invariant across failure classes; the claim test drives session gating from
  the source task and adds a legacy-400 case.

- Docs: tasks.{mdx,zh,ja,ko}.mdx and the GetLastTaskSession SQL comment now
  distinguish execution-log per-row retry (task_id: reuse workdir, conditional
  session) from CLI/API rerun (no task_id: fresh session + fresh workdir).

- Clarify cross-runtime workdir is best-effort: the daemon offers the source
  workdir regardless of runtime (a shared mount may resolve it) and only the
  per-cwd session is runtime-gated.

4fac8d772f feat(attribution): Human Attribution Phase 1 (MUL-4302) (#5150)
* feat(attribution): Phase 1 foundation — provenance schema + resolver (MUL-4302)

Human Attribution, Phase 1 (地基) first increment. Every agent run must be
traceable to exactly one accountable human AND record at which waterfall level
that human was resolved, so a NULL originator can be told apart from a genuine
'no human in the chain'.

- migration 149: add originator_source (waterfall label) + delegation/retry/
  rerun/rule-version lineage + kind-tagged trigger evidence to agent_task_queue.
  No FK, no cascade, no CHECK on the source enum (MUL-4302 §7); nullable ADD
  COLUMNs = fast metadata-only change on the hot queue table.
- internal/attribution: the accountable-human vocabulary (Source, EvidenceKind,
  TriggerKind) + pure, unit-tested classification rules (ClassifyComment/
  ClassifyDirect). No DB, no authorization — provenance labeling only.
- service: attributionFor{IssueTask,TriggerComment} gather facts and delegate to
  the pure classifier; the legacy originator resolvers now delegate here so
  there is one source of truth. originator_user_id's VALUE is unchanged, so the
  Composio-overlay and canInvokeAgent A2A authorization boundaries are
  byte-for-byte preserved (MUL-4302 §1.3).
- enqueueIssueTask / enqueueMentionTask stamp originator_source + evidence;
  CreateRetryTask carries the parent attribution forward and records
  retry_of_task_id so retry and manual rerun stay separable (MUL-4302 §5).

Verified: go build ./..., go vet, gofmt clean; new attribution unit tests +
enqueue stamping integration test green; existing resolve_originator tests
unchanged.

Co-authored-by: multica-agent <[email protected]>

* feat(attribution): split accountable_user_id from originator, close enqueue bypasses (MUL-4302)

Phase 1, per Bohan's decision on the MUL-4302 thread: audit and authorization
answer different questions and get different columns.

- Migration 151 adds agent_task_queue.accountable_user_id (no FK, no cascade).
  Authorization keeps reading ONLY originator_user_id (canInvokeAgent A2A gate,
  Composio overlay); audit/UI/usage read accountable_user_id + source + evidence.
- Invariant (finalizeAttribution, single chokepoint + §11 tests): originator
  non-null ⟹ accountable equals it. The two diverge only when originator is null
  (autopilot / degraded fallback), which is the deferred rule_owner/owner_fallback
  increment; this lands the column + mirror-write so that split has a home.

- Close the NULL-source enqueue bypasses Elon flagged: chat, quick-create,
  deferred-fallback and run_only-autopilot now stamp originator_source + evidence
  (+ accountable where a human exists). Autopilot stays unattributed until the
  rule-version snapshot table lands, but is no longer a silent NULL-source row.
  Retry inherits accountable_user_id like the rest of the attribution lineage.

- Fix assign/promote attribution (§4): a member who assigns/promotes an existing
  issue is now the accountable human (and, by the invariant, originator) ahead of
  the issue creator. Threaded as an OPTIONAL actor override, so comment/rerun/
  autopilot paths keep today's resolution and create-with-assignee (creator ==
  actor) is unchanged. The squad leader gate already judged the same member.

Also merges origin/main: renumbers the attribution migration 149→150 (main took
149 for issue_origin_agent_create) and folds agent_create into ClassifyDirect's
origin inheritance.

go build/vet/gofmt clean; attribution unit tests + service stamp/actor tests +
handler suite pass on a fresh DB migrated through 151.

Co-authored-by: multica-agent <[email protected]>

* docs(attribution): fix accountable NULL semantics + close chat/quick-create evidence boundary (MUL-4302)

Addresses Elon's 2nd-round review on PR #5150 (pre-merge doc/evidence items):

- Migration 151 no longer overclaims NULL. accountable_user_id is NULL not only
  on pre-migration rows but on NEW rows whose audit source resolved no human yet
  (run_only autopilot writes originator_source='unattributed' with NULL
  accountable until rule_owner lands). Header + COMMENT ON COLUMN reworded so a
  schema reader does not misjudge the invariant.

- Chat now uses the UNIFORM evidence pair (kind=chat, ref=chat_session_id), like
  autopilot_run/issue_assignment, instead of relying only on the dedicated
  chat_session_id column — new EvidenceChat kind. Added a service test asserting
  chat stamps direct_human + chat evidence.

- Quick-create is documented as the ONE intentional no-antecedent-row path: no
  comment/issue/session/run exists at enqueue time (the run creates the issue), so
  trigger_evidence_kind/ref stay NULL while the human rides originator/accountable
  and source is direct_human — not a NULL-source bypass.

No authorization behavior change. attribution + service + handler suites pass on a
DB migrated through 151.

* chore(attribution): renumber migrations 150/151 → 157/158 after merging main (MUL-4302)

main's #5162 ("unblock release migrations") renumbered the chat migrations and
took 150 (agent_task_coalesced_comments) and 151 (chat_read_cursor), colliding
with this branch's attribution migrations. Renumber them above main's new highest
(156) so TestMigrationNumericPrefixesStayUniqueAfterLegacySet passes:

- 150_agent_task_attribution      → 157_agent_task_attribution
- 151_agent_task_accountable_user → 158_agent_task_accountable_user

Fixed the internal "migration 150" references in 158's header to 157. Migrations
apply cleanly through 158 on a fresh DB; migration lint green.

* feat(attribution): autopilot rule_owner — accountable = rule version publisher (MUL-4302)

Implements rule_owner (MUL-4302 §3.4), the first attribution source where the
accountable human diverges from the (NULL) authorization originator.

- Migration 159 adds the append-only autopilot_rule_version snapshot table (no FK,
  no cascade); migration 160 adds its CONCURRENTLY lookup index.
- Write-on-publish: CreateAutopilot appends v1 (publisher = creator); UpdateAutopilot
  appends a new version when a SUBSTANTIVE autopilot-row field changes (assignee /
  status / execution_mode) — cosmetic edits (title/description/template) write none.
  Both run inside the existing handler tx (atomic with the autopilot write).
- Dispatch resolution: both autopilot execution modes now resolve the active rule
  version and stamp originator_source='rule_owner', accountable_user_id=publisher,
  rule_version_id=<snapshot>, with originator_user_id left NULL (authorization
  unchanged). run_only stamps CreateAutopilotTask directly; create_issue resolves in
  attributionForIssueTask so both modes attribute identically. A missing version /
  non-member publisher degrades to unattributed — never fabricates a human.
- finalizeAttribution now enforces the invariant ONE-WAY: it mirrors originator onto
  accountable only when originator is valid, leaving an explicitly-set accountable
  (rule_owner / future owner_fallback) intact when originator is NULL. Added
  rule_version_id to CreateAgentTask so the create_issue path persists it too.

Also merges origin/main and renumbers this branch's attribution migrations
150/151 → 157/158 (main's #5162 took 150/151); rule_version table is 159/160.

Tests: attribution unit RuleOwner + one-way invariant table; service integration
tests proving an autopilot-origin issue stamps rule_owner + rule_version_id (and
degrades to unattributed with no version). Full service/attribution/handler/
migration suites pass on a DB migrated through 160; build/vet/gofmt clean.

Deferred (same PR): trigger-table republish (cron/webhook/event_filters) and
system-pause/archive versioning; owner_fallback + fail-closed; manual rerun.

* fix(attribution): manual autopilot trigger → direct_human to the triggering member (MUL-4302)

Elon's blocking finding: a member manually triggering an autopilot was attributed
rule_owner (accountable = rule publisher, originator NULL) like a schedule/webhook
run, so member B triggering member A's autopilot landed accountable=A and carried
no originator authorization context for the run. Per MUL-4302 §4 a manual "run now"
is a direct human action and must attribute direct_human to the triggering member.

- Thread the triggering member from TriggerAutopilot into dispatch: new
  DispatchAutopilotManual carries actorUserID (resolved via resolveActor +
  memberActorUserID, so only a member actor is a human; an A2A agent actor falls
  back to rule_owner). DispatchAutopilot / DispatchAutopilotForPlan keep their
  public signatures (pass an invalid actor); only the internal dispatchAutopilot /
  dispatchCreateIssue / dispatchRunOnly gained the param, so the many existing
  callers are untouched.
- run_only: dispatchRunOnly stamps direct_human (originator == accountable ==
  actor, no rule_version) for a manual actor, else rule_owner. CreateAutopilotTask
  gains an originator_user_id param for the manual case.
- create_issue: dispatchCreateIssue enqueues a manual trigger via the actor-carrying
  *WithHandoff entry points; attributionForIssueTask's autopilot-origin rule_owner
  branch is now guarded on !actorUserID.Valid, so a valid actor falls through to the
  direct_human override. Both execution modes attribute identically.
- schedule / webhook keep rule_owner (no actor). Trigger-table + system-pause/archive
  versioning remain the pre-merge follow-ups.

Tests: the run_only row assertion Elon asked for (schedule → rule_owner row on
CreateAutopilotTask), plus manual direct_human on BOTH modes (run_only and
create_issue), including a manual actor distinct from the rule publisher. Full
service/attribution/handler/migration/scheduler/cmd suites pass on a DB migrated
through 160; build/vet/gofmt clean.

* feat(attribution): owner_fallback + fail-closed policy, and manual-rerun direct_human (MUL-4302)

Two of the three remaining Phase 1 items (trigger-table / system-pause versioning
is deferred — see PR description).

owner_fallback + fail-closed (§1/§3.5) — the never-null accountable guarantee:
- attribution.OwnerFallback degrades an UNATTRIBUTED result to owner_fallback:
  accountable = agent owner, originator stays NULL (audit-only, authz untouched),
  Source.Precise()==false. finalizeAttribution's one-way invariant already allows
  accountable-set / originator-NULL divergence, so nothing else changes.
- Migration 161 adds workspace.attribution_fail_closed (default FALSE) + a lean
  GetWorkspaceAttributionFailClosed read. (Also added the column to ListWorkspaces'
  explicit column list so its row type stays db.Workspace.)
- applyAttributionFallback is applied at every enqueue boundary (issue, mention,
  chat, quick-create, deferred-fallback, autopilot run_only): unattributed →
  owner_fallback (agent owner) by default, or ErrAttributionFailClosed when the
  workspace is fail-closed, which the caller surfaces to refuse the enqueue (the
  run does not start). So no run is left without an accountable human, and a
  compliance workspace can block unattributable runs instead.

manual rerun (§5) — a rerun is a NEW direct_human trigger to the rerunning member:
- RerunIssue threads the acting member (resolved in the handler via resolveActor)
  down to enqueueRerunTask, and attributionForIssueTask is now actor-first so the
  actor wins over an INHERITED trigger comment (a rerun keeps the comment for the
  daemon's prompt context but must attribute to whoever clicked rerun, not the
  original comment's human).
- rerun_of_task_id lineage is recorded via a targeted SetAgentTaskRerunOf update on
  the rerun path only (keeping the shared CreateAgentTask insert untouched), so
  system retry (retry_of_task_id) and human rerun stay separable in reporting.

Tests: OwnerFallback unit test; owner_fallback + fail-closed-refusal + manual-rerun
(direct_human + rerun_of_task_id) service tests; the prior "degrades to unattributed"
test updated to owner_fallback. Full service/attribution/handler/migration/scheduler/
cmd suites pass on a DB migrated through 161; build/vet/gofmt clean.

* fix(attribution): close fail-open holes + move rerun_of_task_id into creation snapshot (MUL-4302)

Addresses Elon's two must-fixes on PR #5150.

1. accountable-never-null / fail-closed had fail-open holes. applyAttributionFallback
   now, for an UNATTRIBUTED run, refuses the enqueue (ErrAttributionFailClosed) in
   THREE cases instead of silently degrading to a runnable NULL-accountable task:
   - workspace policy read fails (or no workspace) → fail closed; we cannot confirm
     fallback is permitted, so we don't run an unattributable task on a DB hiccup.
     (Only the rare unattributed path pays this; precise runs never read the policy.)
   - workspace is fail-closed → refuse (unchanged).
   - owner_fallback has no valid agent owner → refuse rather than enqueue a task with
     a NULL accountable_user_id.
   ErrAttributionFailClosed's doc now covers all three "cannot guarantee an
   accountable human" refusals. Added missing-owner / policy-read-failure /
   precise-passthrough tests.

2. manual rerun rerun_of_task_id was a post-notify UPDATE (race: the queued event /
   daemon claim could see rerun_of_task_id = NULL, and a failed update degraded the
   run to a plain direct_human). It now rides the CreateAgentTask insert — threaded
   through enqueueIssueTask / enqueueMentionTask as a creation param (like
   retry_of_task_id) so it is written in the same statement before the daemon is
   notified. Removed the SetAgentTaskRerunOf follow-up query.

Also merges origin/main (unrelated CLI fix #5167, no conflict). Full service /
attribution / handler / migration / scheduler / cmd suites pass on a DB migrated
through 161; build / vet / gofmt clean.

Co-authored-by: multica-agent <[email protected]>

* feat(attribution): rule_owner versioning on trigger edits + system-pause/archive (MUL-4302)

The final remaining Phase 1 item: substantive publishes beyond the autopilot row now
republish the rule version, so a run's rule_owner accountable follows whoever last
changed what the rule does.

- Extracted the config-summary + insert into service.RecordAutopilotRuleVersion so
  the handler and the (different-package) failure monitor share one writer; the
  handler's recordAutopilotRuleVersion is now a thin wrapper.
- Trigger edits: UpdateAutopilotTrigger and DeleteAutopilotTrigger republish the rule
  version with the acting member as publisher, ATOMICALLY (tx-wrapped mutation +
  version write, mirroring CreateAutopilot/UpdateAutopilot). CreateAutopilotTrigger
  republishes best-effort — the webhook path mints its token with a retry loop that
  cannot share one tx, and a create is usually initial setup already covered by v1;
  a failed write there is benign (active version stays the current publisher, the new
  trigger fires under it, no immediate daemon claim rides it).
- Archive (DeleteAutopilot) republishes (member, status=archived), tx-wrapped.
- System auto-pause (failure monitor) republishes with a 'system' publisher,
  best-effort — a background sweep to a non-dispatching state (a paused autopilot
  never dispatches; a later member resume supersedes).
- RotateWebhookToken / SetSigningSecret deliberately do NOT version: they rotate
  credentials, not the rule's behavior (not §3.4 substantive).

Semantics: a system-published (no-member) active version degrades dispatch to
unattributed → owner_fallback, never fabricating a human.

Tests: republish-reattributes (member A → member B supersedes → dispatch resolves to
B; system publisher → unattributed). Full service/attribution/handler/migration/
scheduler/cmd suites pass on a DB migrated through 161; build/vet/gofmt clean.
Also merges origin/main (unrelated frontend feature #5074).

Co-authored-by: multica-agent <[email protected]>

* fix(attribution): make trigger-create rule-version republish atomic (MUL-4302)

Addresses Elon's final Phase 1 blocking finding: CreateAutopilotTrigger recorded the
rule-version republish best-effort AFTER the trigger insert. If member B added a
schedule/webhook trigger to member A's autopilot and the version write failed, future
schedule/webhook dispatches would keep attributing to A — violating the rule_owner
invariant that the last member to substantively change the rule owns future runs
("no immediate daemon claim" doesn't save it, since the miss surfaces at the LATER
trigger firing).

Both create paths now write the version in the SAME tx as the trigger INSERT:
- schedule create: wrap CreateAutopilotTrigger + recordAutopilotRuleVersion in one tx.
- webhook create: each mint-with-retry attempt runs in its own tx (insert + version
  commit together; a token collision rolls that attempt back and retries with a fresh
  token; a version-write failure rolls the trigger back). Passes ap + the acting
  member id into the helper.
- removed the best-effort recordTriggerRuleVersionBestEffort helper (and the now-unused
  slog import).

Test: TestCreateTrigger_RepublishesRuleVersionAtomically drives both create paths
through the handler and asserts a rule version is published by the acting member.
Existing webhook/trigger/archive handler tests still pass. Also merges origin/main
(unrelated avatar feature #5074). Full service/attribution/handler/migration/
scheduler/cmd suites pass on a DB migrated through 161; build/vet/gofmt clean.

* feat(attribution): Phase 2.1 — surface run attribution on the task API (MUL-4302 §9)

First Phase 2 (visibility) increment: the agent-task API now returns the resolved
accountable-human provenance so the UI can render an "on behalf of" badge.

- AgentTaskResponse gains an `attribution` object: source label (never blank —
  pre-migration NULL renders "unattributed") + `precise` flag (false for the degraded
  owner_fallback / backfill / unattributed sources), the initiator (accountable) and
  originator (authorization) user refs, the evidence {kind, ref_id} pointer, and the
  rule_version / delegated / retry / rerun lineage ids.
- The label + evidence + raw ids are built in the PURE taskToResponse (no DB), so
  every task response carries them. Names are hydrated separately, only on the
  user-facing surfaces (ListAgentTasks, ListWorkspaceAgentTaskSnapshot, RerunIssue,
  CancelTaskByUser) — daemon-claim paths stay lean.
- Hydration resolves initiator/originator from the GLOBAL user table (departed-member
  safe) via a new batch GetUsersByIDs query (no N+1); best-effort, so a lookup hiccup
  leaves the raw ids intact.

Tests: pure taskAttributionBase (direct_human / rule_owner NULL-originator /
owner_fallback degraded / pre-migration→unattributed) + DB hydration (fills known
ref, leaves unknown id un-filled, skips nil). Full handler/service/attribution/
migration/scheduler/cmd suites pass on a DB migrated through 161; build/vet/gofmt
clean. The field is additive — the frontend's parseWithFallback ignores unknown keys,
so nothing breaks until the UI increment consumes it.

Also merges origin/main (unrelated editor feature #5090).

Remaining Phase 2 (next increments, same PR): frontend zod schema + "on behalf of"
badge + evidence-chain jump; append-only correction events (write + display).

Co-authored-by: multica-agent <[email protected]>

* feat(attribution): Phase 2.2 — on-behalf-of badge in the execution log (MUL-4302 §9)

Surface the accountable human on every agent run row:
- AttributionBadge composes Badge + ActorAvatar, shows "on behalf of <member>"
  with the resolution source as a tooltip; degraded (non-precise) attribution
  gets a warning tone, and an unresolved initiator renders an explicit
  "no responsible member" chip.
- Wire the badge into both active and past rows of the execution log.
- Mirror the attribution shape into AgentTaskResponseSchema (defensive, .loose())
  so the cancel-task path carries it through zod; add parse tests.
- Export TaskAttribution/AttributionUser/TaskEvidence from @multica/core/types
  and add the attribution block to all four issues.json locales.

Co-authored-by: multica-agent <[email protected]>

* fix(attribution): hydrate initiator names on issue-facing task endpoints + bound the badge (MUL-4302 §9)

Address Elon's PR #5150 review:
- ListTasksByIssue (the execution-log data source), GetActiveTaskForIssue and the
  issue-scoped CancelTask now call hydrateTaskAttributions, so the "on behalf of
  <member>" badge shows the real member name on issue detail instead of falling
  back to "someone". Mirrors the existing ListAgentTasks / snapshot behavior.
- AttributionBadge: cap width (max-w-40, min-w-0) and truncate the name span so a
  long name / narrow right column can't squeeze out trigger/status/actions; keep
  the avatar shrink-0.
- Add a handler test asserting the issue task list returns a hydrated
  attribution.initiator.name.

* fix(attribution): use semantic AvatarSize 'xs' for the badge avatar

main refactored ActorAvatar.size from a raw pixel number to the semantic
AvatarSize union (packages/ui/lib/avatar-size). Switch the on-behalf-of badge
avatar from size={14} to size="xs" (16px) after merging main.

* fix(attribution): stage-cascade falls back to parent-issue provenance, not agent owner (MUL-4302)

When closing the last sub-issue in a Stage wakes the parent's assignee agent, the
run was enqueued via a system-authored child-done comment with no actor, which the
resolver classified as unattributed and then degraded to owner_fallback (the agent's
own owner). That is the wrong accountable human: the woken run should be accountable
to whoever caused the parent issue to exist.

attributionForIssueTask now detects a system-authored trigger comment and falls
through to the parent issue's own provenance — the same creator / agent_create-origin
/ autopilot-origin chain a direct enqueue resolves (so an agent-decomposed parent
attributes via delegation to the human who drove it; a member-created parent to that
member; an autopilot parent to the rule publisher). owner_fallback is now only the
last resort when the parent provenance itself has no human.

- Extract attributionFromComment so attributionForIssueTask can inspect author_type
  without a second GetComment; authorization resolution stays byte-identical.
- Add a DB-backed test asserting a system child-done comment resolves to the parent
  issue's origin human (delegation), not owner_fallback.

* feat(attribution): autopilot runs attribute to the firing trigger's creator (MUL-4302)

Per Bohan: an autopilot schedule/webhook run should be accountable to the human
who created the SPECIFIC trigger that fired it, not the rule publisher. (Manual
triggers already attribute to the invoking member via direct_human — unchanged.)

- Migration 162: add autopilot_trigger.created_by_type/created_by_id (nullable, no
  FK/cascade). Capture the creating member at both trigger-create sites (schedule +
  webhook).
- New precise source trigger_owner: originator stays NULL (an autonomous fire
  carries no human authorization — same authz-safe divergence as rule_owner),
  accountable = the trigger's member creator.
- triggerOwnerAttribution resolves run.trigger_id → creator; wired into run_only
  dispatch and the create_issue path (bridging issue → active run → trigger_id).
  Legacy triggers with no recorded creator, and agent-created triggers, degrade to
  rule_owner then owner_fallback — nothing regresses.
- Frontend: trigger_owner source label in all four locales + badge switch case.
- Tests: attribution TriggerOwner unit + Precise/invariant; DB-backed resolver
  tests (member creator → trigger_owner; creatorless → rule_owner fallback).

Co-authored-by: multica-agent <[email protected]>

* fix(attribution): mirror accountable_user_id on comment-coalescing merge (MUL-4302)

The one-way invariant is 'originator_user_id IS NOT NULL ⟹ accountable_user_id =
originator_user_id', enforced at finalizeAttribution for enqueues and preserved by
the retry-clone (copies both columns). But MergeCommentIntoPendingTask (main #5192)
re-stamps originator_user_id to the newly-coalesced comment's human WITHOUT touching
accountable_user_id — so folding member B's comment into member A's queued task left
originator=B / accountable=A, violating the invariant. Re-stamp accountable to mirror
the new originator (same thing finalizeAttribution does). Add a DB-backed regression
test.

Co-authored-by: multica-agent <[email protected]>

* fix(attribution): Elon's 3 must-fixes + DB cross-column invariant CHECK (MUL-4302)

Bohan approved Elon's plan; this closes the three attribution boundaries he flagged
and locks the one-way invariant at the DB.

1. Delegation now inherits the parent's ACCOUNTABLE, not just its originator. An
   autopilot-rooted chain (parent originator NULL, accountable = trigger creator)
   @mentioning an agent / creating a sub-issue used to drop to unattributed →
   owner_fallback and fail-closed workspaces wrongly rejected the fan-out. Added
   ParentAccountable/OriginAccountable to CommentFacts/DirectFacts; ClassifyComment/
   ClassifyDirect copy accountable down (source=delegation, precise, originator NULL)
   so the chain root stays stable at any depth (§3.2).
2. The direct-chat send path (SendDirectChatMessage, MUL-4351) wrote only
   originator_user_id — no accountable/source/evidence, a NULL-source bypass. It now
   stamps the full direct_human attribution like EnqueueChatTask.
3. Comment-coalescing merge re-attribution is now ATOMIC: MergeCommentIntoPendingTask
   re-stamps the whole snapshot (person columns + source + delegation lineage + rule
   version + evidence) of the new comment, not just the two person fields, so a merged
   run never shows B accountable while pointing at A's stale source/evidence.
4. Migration 169: NOT VALID CHECK (originator_user_id IS NULL OR (accountable_user_id
   IS NOT NULL AND accountable_user_id = originator_user_id)). Enforces the invariant
   on every new write (the class of bug #5192 introduced); historical rows not blocked,
   VALIDATE after Phase 3 backfill. Updated test fixtures that seeded originator-only
   rows to also set accountable.

Merged latest main (renumbered attribution migrations 163–168 after main took 161/162;
merged the retry-clone chat_input_task_id + attribution columns). Verified: go build/
vet, attribution/service/handler/cmd-server tests on a migrated DB, frontend
typecheck/lint/tests.

* fix(attribution): trigger responsibility transfers to effective publisher; fail-closed comment merge

Elon final-review must-fix 1 (MUL-4302): trigger_owner now resolves to the
member CURRENTLY responsible for the firing trigger's effective config, not the
fixed creator. Per-trigger published_by on autopilot_trigger, seeded to the
creator and re-stamped to the editor on a substantive edit — a trigger-scoped
edit bumps only that row (UpdateAutopilotTrigger), an autopilot-level edit bumps
all its triggers (UpdateAutopilot). Editing one trigger never reassigns another.
Adds real dispatchRunOnly transfer test + resolver-level isolation test.

Must-fix 3: AttributionForMergedComment reuses applyAttributionFallback and
returns ErrAttributionFailClosed; the merge caller refuses on fail-closed,
keeping the queued task's original precise snapshot instead of degrading it to
owner_fallback. Adds regression test.

Renumbered attribution migrations to 166-172 after merging main.

Co-authored-by: multica-agent <[email protected]>

* fix(attribution): make migration 172 invariant CHECK upgrade-safe (Option A)

Elon final-review must-fix 2 (MUL-4302), rollout chosen by Bohan. The NOT VALID
CHECK still checks a pre-existing row on any later UPDATE (even one not touching
attribution columns), so cross-deployment stale queued/running tasks (originator
set, accountable NULL from before migration 167) would fail on their next
claim/complete/cancel. Exempt exactly those legacy rows via 'originator_source
IS NULL' — that column was added in 166 with no backfill, so it is NULL only on
pre-migration rows and non-NULL on every attribution-aware write. New writes
stay fully enforced; the #5192 bypass class (source always set) is unaffected.
Phase 3 backfills legacy rows then drops+re-adds the strict form + VALIDATE.

Adds TestAttributionInvariantCheck_ExemptsLegacyRows (legacy row survives a
status UPDATE) and updates the reject-bypass test to the enforced regime.

Co-authored-by: multica-agent <[email protected]>

* fix(attribution): pin substantive/cosmetic edit boundary for trigger transfer

Elon re-review must-fix 1: an autopilot-level edit only transfers trigger_owner
responsibility when it changes what the automation instructs or who/whether it
runs. autopilotRuleSubstantiveChange now includes description (the run Prompt)
and issue_title_template; title and project_id stay cosmetic/routing.
UpdateAutopilotTrigger no longer transfers on every PATCH — it compares the
persisted before/after and transfers only on a real cron/timezone/enabled/
event_filters change, not a label-only or no-op PATCH. Adds real handler tests
(prompt->all, title->none, cron->one+isolation, label->none, no-op->none).

Must-fix 3: real merge-path regression (TestMergeCommentIntoPendingTask_
FailClosedKeepsOriginalSnapshot) drives mergeCommentIntoPendingTask and asserts
a fail-closed workspace preserves the queued task's full snapshot; fail-open
control completes the owner_fallback merge.

Docs: migration 172 comment reworded to legacy-writer/unbackfilled-lineage
semantics (source NULL is not strictly pre-migration); PR description synced.

Migration renumber vs latest main (must-fix 2) deferred to pre-launch per Bohan.

* feat(admission): unify dispatch outcome + close rerun/chat/autopilot invoke holes (MUL-4525)

P0 first increment toward a platform-wide execution-admission contract so a
user who names an execution target always gets a definite result and never a
silent no-op, and so blocked targets are reported without leaking private-agent
details.

Backend:
- New shared contract (handler/admission.go): DispatchOutcome / DispatchStatus
  (queued/coalesced/deferred/blocked) + stable, enumeration-safe
  DispatchReasonCode set, plus writeDispatchBlocked() whose legacy `error`
  string never reveals target existence.
- Rerun (task.go / task_lifecycle.go): re-validate the operator can invoke the
  RESOLVED target agent (historical agent for a task_id rerun) before any
  cancel/enqueue; blocked returns a structured 403 and mutates nothing
  (ErrRerunInvokeNotAllowed).
- Chat send (chat.go): re-run canInvokeAgent on every send, not just the softer
  canAccessPrivateAgent view gate; a revoked permission blocks before the
  message/attachments/task persist.
- Autopilot manual "run now" (service/autopilot.go): admission now keys on the
  current CLICKER, not the autopilot creator — clicker admission and clicker
  attribution no longer fork. Automation (schedule/webhook) still falls back to
  the creator gate. Added reason_code to the run response for the UI.

Frontend:
- triggerAutopilot response is schema-parsed; handleRunNow branches on run
  status and shows a localized, reason_code-based warning for skipped/failed
  instead of a false-success toast.
- Chat send and rerun surface the structured 403 reason_code as localized
  toasts (dispatchReasonCode helper) instead of a generic failure.
- Additive fields only; older clients keep working. i18n added to all 4 locales.

Tests: rerun fail-before-mutation gate, autopilot clicker-vs-creator fork
(service + handler), reason-code classification, and a malformed-response
schema test. Backend handler+service suites and FE typecheck/lint green.

* test(cmd/server): thread nil invoke gate through RerunIssue call sites (MUL-4525)

Co-authored-by: multica-agent <[email protected]>

* fix(admission): typed reason codes + run-now whitelist + real security tests (MUL-4525)

Addresses Elon's review of the P0 first increment (must-fix 1–3).

1. Run now no longer has a false-success branch. handleRunNow now classifies on
   a whitelist via a pure runNowToastKind(): only issue_created/running →
   success; skipped → warning; failed and any unknown/future status → error. Add
   run-now-toast unit test over all five status classes plus reason-code → key
   mapping.

2. reason_code is a typed value decided at the admission source, not
   reverse-engineered from English failure text. New leaf package
   internal/dispatch holds the canonical ReasonCode enum (shared by handler +
   service so they can never drift). shouldSkipDispatch / errDispatchSkipped /
   the fail path now carry a typed code through DispatchAutopilotManual straight
   into the response; the substring classifier is deleted. Fixes the two missed
   branches: attribution fail-closed → attribution_blocked (typed errors.Is),
   "agent has no runtime bound" → runtime_offline. Regression tests for both.

3. Security acceptance tests exercise the REAL handlers, not injected callbacks:
   - Chat: create session while invokable → revoke invoke (flip to private, keep
     owner-view) → send returns 403 + reason_code with zero chat_message / task

* test(admission): make must-fix 3 acceptance tests prove the invariant (MUL-4525)

Addresses Elon's round-3 narrow review — the two security tests were not yet
falsifiable against the bugs they must catch.

- Rerun: after enqueuing the historical task, reassign the issue to a SECOND
  agent that the denied user CAN invoke. Now the current assignee and the
  task_id agent differ, so a rerun that wrongly validated the current assignee
  would let the denied user through — the 403 proves the gate is keyed on the
  historical private agent. The allow case now asserts the reran task's agent_id
  is the historical agent, not the current assignee.

- Chat: the blocked send now carries a valid, still-unbound attachment. After
  the 403 the test asserts the attachment's chat_session_id and chat_message_id
  are both still NULL, guarding against anyone moving attachment binding ahead
  of the invoke gate.

Test-only. Full internal/handler Go suite green.

* feat(comments): surface blocked @mention trigger_outcomes instead of silent no-op (MUL-4525 §2)

A comment that @mentions an agent/squad the author cannot invoke used to save
with zero feedback — the user assumed a bug. Now the explicit-mention path
reports a per-target outcome on both preview and create/edit.

Backend (server/internal/handler/comment.go):
- resolveMentionedAgentCommentTriggers collects blocked outcomes instead of a
  silent `continue`. The invoke gate is evaluated BEFORE any archived/runtime
  state is read, so a caller who cannot invoke a private target only ever sees
  the generic invocation_not_allowed and can never enumerate its existence.
- enqueueCommentAgentTriggers returns queued/coalesced/deferred/blocked per
  explicit mention; enqueue errors are typed (attribution_blocked via
  errors.Is), not swallowed. Implicit routing (assignee/thread/conversation)
  carries no outcome — the user never named those targets.
- trigger-preview returns `blocked[]`; create/edit return additive
  `trigger_outcomes[]`. One blocked mention never fails the comment.

Frontend:
- Composer shows a warning chip for blocked mentions before sending; after
  sending, a "posted, but N not triggered" toast (blocked-only; coalesced/
  deferred are success-shaped). Additive schema + defensive parse; i18n ×4.

Tests: handler partial-success + enumeration-safety acceptance tests; core
outcome-parse + preview-schema tests; hook/parity updated. Backend
handler+service suites and FE typecheck/lint/vitest green.

* i18n(admission): clearer, consistent blocked-trigger copy (MUL-4525)

Reword the awkward "you are not allowed to run this autopilot's assignee" and
polish all MUL-4525 blocked/partial copy across en/zh-Hans/ja/ko:

- Unify on "you don't have permission to use this <agent|target>" (zh: 没有…的
  使用权限) for autopilot Run now, comment mentions, rerun, and chat send —
  replacing the various "not allowed to run/trigger" phrasings.
- Align zh to the glossary term 智能体 (was mixed "Agent"), matching the
  surrounding UI voice (e.g. agent_link_no_access).
- Drop jargon: "blocked by an admission policy"/"被准入策略拦截" → "the run was
  blocked"/"本次运行已被拦截"; "attributed"/"归因" → plainer wording.
- Comment copy counts "mentions" (was "targets") for consistency with the chip.

Backend dispatchBlockedFallbackMessage (old-client English fallback) reworded to
match; its enumeration-safety test assertion updated. Copy-only — no key/logic
changes; parity + typecheck green.

* fix(comments): one outcome per explicit mention + FE success whitelist (MUL-4525)

Addresses Elon's round-2 review of the §2 comment trigger_outcomes.

1. Separate execution dedup from per-target outcomes. resolveMentionedAgent-
   CommentTriggers now returns triggers (deduped by executing agent) AND one
   commentMentionTarget per EXPLICIT mention. enqueueCommentAgentTriggers returns
   a per-executing-agent result map; commentTriggerOutcomes fans each agent's
   status to every target that resolved to it. So @Agent A + @Squad S(leader=A)
   coalesces to ONE task but yields TWO outcomes. The squad-leader self-suppress
   branch now returns a definite `deferred` outcome instead of no result. New
   CreateComment test asserts 1 task, 2 outcomes.

2. Frontend no longer treats an unknown status as success. unhandledComment-
   TriggerOutcomes whitelists queued/coalesced/deferred as handled; blocked and
   any unknown/future/empty status warn (mirrors the Run now whitelist). The
   preview schema's `blocked` now drops malformed entries INDIVIDUALLY instead of
   z.array(...).catch([]) discarding the whole set. Regression tests for the
   unknown status and the per-item drop.

Backend handler suite + go vet, FE typecheck/lint/vitest green.

* fix(comments): honest role + status in trigger_outcomes fan-out (MUL-4525)

Addresses Elon's round-3 review of the §2 fan-out.

1. Execution merge preserves the squad-leader role instead of first-mention-
   wins. The dedup now UPGRADES an already-added plain @agent trigger to a
   @squad-leader trigger for the same agent, so @Agent A + @Squad S(leader=A)
   always runs as a leader task (is_leader_task + squad_id=S) regardless of
   mention order — the daemon still injects S's briefing. When two DIFFERENT
   squads share one leader, the single run carries one squad's context and the
   other squad is reported `coalesced` (folded), never a second `queued`. The
   enqueue result now records the executed squad so the fan-out can tell them
   apart. Tests assert the task role in both orders and the two-squad split.

2. Squad-leader self-suppression no longer fakes success. The self-trigger
   guard keys on the latest task ROLE with no status filter, so a long-completed
   task also suppresses; reporting `deferred/already_active` when nothing is
   active was a false success. The branch now reports `deferred` only when a
   real non-terminal task is active (its reconcile covers the comment), else a
   non-success `blocked` + new `already_handled` reason. Fixed the reversed
   helper-semantics comment. New handler test covers the completed-task branch.

Backend handler+service suites and go vet green.

* fix(comments): fail-closed active-task check, never fake deferred (MUL-4525)

Elon round-4 must-fix: hasActiveTaskForIssueAndAgent swallowed DB errors by
returning true, so both call sites could turn a query failure into a
success-shaped `deferred/already_active` — a silent false success, exactly what
this issue forbids for admission-query failures.

- hasActiveTaskForIssueAndAgent now returns (bool, error).
- Two pure decision helpers govern the branches, fail closed on error:
  - decidePostMergeMiss: on query error, do NOT enqueue a fresh task (duplicate
    concurrent-run risk) AND report non-success blocked/internal_error; a
    confirmed active task defers; a confirmed-none enqueues fresh.
  - decideSuppressedLeaderOutcome: on query error, blocked/internal_error; a
    confirmed active run defers; else self_trigger_suppressed. Never a fabricated
    deferred.
- Renamed reason already_handled -> self_trigger_suppressed (Elon non-blocking
  note): the old name implied the new comment was already processed, but the
  real meaning is a suppressed self-trigger.

Deterministic unit tests cover the query-failure branch at both call sites
(no fresh enqueue, non-success outcome) — a real DB fault can't be forced
through valid handler inputs, and the decision is what governs the behavior.
Backend handler+service suites and go vet green.

* fix(comments): honest merge outcome — refused merge is blocked, not fake coalesced (MUL-4525)

A pending-task merge previously reported success (coalesced) even when it
was refused or failed: attribution fail-closed and unknown DB errors both
returned handled=true, so the caller recorded coalesced for a merge that
never happened. mergeCommentIntoPendingTask now returns a distinguishable
commentMergeResult; commentMergeTerminalOutcome maps a real merge to
coalesced, a fail-closed refusal to blocked/attribution_blocked, and any
other failure to blocked/internal_error. Only "no queued task to fold"
falls through to the active-task decision. Adds pure coverage of the
mapping plus a fail-closed regression asserting the non-success outcome
and unchanged task count.

Co-authored-by: multica-agent <[email protected]>

* fix(comments): name blocked @mentions in preview + toast instead of a vague count (MUL-4525)

The blocked-trigger preview showed a red "1 mention won't trigger" with no
name, and the post-send toast said "but 1 mention wasn't triggered" — the
user can't tell which target or why. Now each blocked mention renders its own
chip named from the mention markup the user typed ("Go · No permission"),
with an error indicator and a short reason; the toast names the single target
too. The wire outcome still omits the target name (enumeration-safety) — the
label comes from the user's own draft, so nothing new is disclosed.

Shares a blocked-trigger-copy module (long + short reason labels) between the
chip and the toast, and a pure mentionLabelsByTarget/parseMentions helper in
core (fresh regex per call — a shared global leaked lastIndex). Adds core +
chip tests; drops the now-unused trigger_blocked_count keys across locales.

* feat(attribution): accountable-member avatar on agent task rows + transcript header (MUL-4302)

Surface who each agent run is on behalf of where runs are actually
browsed:
- Agent detail activity tab: an avatar-only AttributionBadge on every
  task row's meta line (Now + Recent work), tooltip carries the name +
  resolution source.
- Execution-record (transcript) dialog header: the full on-behalf-of
  badge next to the status pill.

Adds a compact variant="avatar" mode to AttributionBadge, reusing its
source-label mapping and degraded-attribution tone. Renders nothing when
a run has no resolved accountable member.

YYClaw 9eddcaff10 fix(chat): defer cancellation-time finalization until the task transcript is stable (#5246)
A quick Stop before the agent's first token no longer races a late reply. Started-but-empty cancellations defer the empty/non-empty judgment until the daemon acks its transcript flush (or a grace-period sweeper fires), then settle to a single outcome. Empty outcomes persist a durable, creator-authorized draft restore (fetched/consumed via a dedicated endpoint, reconnect-safe and at-most-once) instead of broadcasting the prompt over the workspace bus.

c3dd9ec845 Machine-level batch task claim endpoint (MUL-4257) (#5193)
* feat(daemon-claim): machine-level batch task claim endpoint (MUL-4257)

Collapse the per-runtime /tasks/claim poll fan-out into a single machine-level
batch claim to cut /api/daemon claim request volume.

Server:
- agent.sql: = ANY(runtime_ids) batch variants of the claim queries
  (ListQueuedClaimCandidatesByRuntimes, PromoteDueDeferredTasksForRuntimes,
  ReclaimStaleDispatchedTasksForRuntimes); runtime.sql: GetAgentRuntimes(= ANY)
  so a whole machine's runtimes are resolved/promoted/reclaimed/listed in a
  constant number of queries instead of N.
- service.ClaimTasksForRuntimes: claim up to max_tasks across a runtime set,
  preserving per-(issue,agent) serialization, the concurrency cap, the
  empty-claim cache short-circuit, and every dispatch side effect. Batch
  promote replays the per-row side effects (task:queued + empty-cache Bump).
- handler.ClaimTasksByRuntime (canonical POST /api/daemon/tasks/claim, with a
  transitional /claim alias): validates daemon_id (required; must match the
  mdt_ token) and rejects runtimes bound to a different daemon (group-ownership
  check mirroring the WS path); resolves+authorizes each runtime_id; claims;
  and finalizes each task through the SAME FinalizeTaskClaim as the per-runtime
  endpoint (atomic token + delivered_comment_ids receipt), requeueing the exact
  claim and omitting it on failure. buildClaimedTaskResponse is extracted from
  the per-runtime handler and returns the delivered-comment ids plus a
  structured *claimBuildFailure so both paths share identical payload building
  and failure semantics (workspace-isolation, chat-input load/empty).
- max_tasks: negative -> 400, zero -> empty (never coerce to 1), positive
  capped at 32. runtime_ids parsed with non-panicking util.ParseUUID.

Daemon:
- Client.ClaimTasks posts daemon_id + runtime set + free-slot count to the
  canonical path under a short request-scoped timeout, bounding the
  head-of-line coupling the per-runtime pollers avoid (MUL-1744).

Tests: service batch drain / max_tasks cap / deferred-promote receipt /
finalize-failure rollback+requeue; handler routing + token, cross-workspace
skip, cross-daemon skip, daemon_id required, owner-missing cancel,
max_tasks=0/negative, invalid-uuid skip, comment delivery receipt, stale-reclaim
replacement receipt; client posts/parses (daemon_id + canonical path).

Follow-up: cut the daemon pollLoop over to a single batched poller (flips the
MUL-1744 isolation contract; needs its concurrency tests redesigned).

* feat(daemon-ws): generic WS request/response transport for daemon RPC (MUL-4257)

Add a generic daemon->server request/response layer over the existing WS
control connection, the transport for WS-first claim (HTTP fallback):
- protocol: daemon:rpc_request / daemon:rpc_response envelopes with a
  correlation request_id + method + body, and an rpc-v1 capability gate.
- daemonws.Hub: SetRPCHandler + goroutine-dispatched handleRPCFrame (bounded
  by a per-connection in-flight cap) that echoes the request_id; missing
  handler / saturation return non-2xx so the daemon falls back to HTTP.
  Read limit raised to 64KB for rpc requests carrying a runtime set.
- hub tests: round-trip, handler-error->non-2xx, no-handler->503.

* feat(daemon-ws): WS-first task claim over the generic RPC transport (MUL-4257)

Bind claim to the WS request/response layer, with HTTP fallback:
- server: handler.DaemonRPCHandler adapts a daemon:rpc_request (method
  tasks.claim) to the existing HTTP ClaimTasksByRuntime via a synthetic
  in-process request carrying the WS connection's identity (daemon_id +
  workspace + capabilities), so all auth / payload-building / finalization is
  reused unchanged. Wired via daemonHub.SetRPCHandler. ClientIdentity now
  captures X-Client-Capabilities so capability gating matches the HTTP path.
- daemon: wsRPCClient correlates responses by request_id over the shared WS
  connection; attached to the live connection's write channel (guarded so a
  Call racing teardown never sends on a closed channel) and detached on
  disconnect. rpc_response frames are routed in the read loop.
  Daemon.ClaimTasksWSFirst issues tasks.claim over WS and falls back to the
  HTTP claim endpoint on any transport failure (no conn / buffer full /
  timeout) — wired into the poller at the poller cutover.
- tests: handler tasks.claim RPC end-to-end (claims + dispatches) + unknown
  method 404; daemon wsRPCClient round-trip / timeout / unavailable /
  server-error / detach-fails-pending (all under -race).

* feat(daemon): cut claim poller over to machine-level ClaimTasksWSFirst (MUL-4257)

Replace the per-runtime HTTP poll loop with a single batch poller: each cycle
acquires all free execution slots (slot-before-claim) and issues ONE
ClaimTasksWSFirst across every runtime the daemon hosts (WS-first, HTTP
fallback), dispatching each returned task to its runtime. Wakeups (targeted /
catch-up / runtime-set change) collapse to one nudge. Removes runRuntimePoller
+ runtimePollOffset. The WS handshake now advertises the same capabilities as
HTTP (+ rpc-v1) so WS-built claim payloads keep skill-ref / coalesced-comment
gating.

Trades per-runtime isolation (MUL-1744) for one request, bounded by the short
per-request WS timeout / client timeout. Tests: batch poller claims across
runtimes + skips-at-capacity + pollLoop shutdown drain (replacing the
per-runtime poller tests); heartbeat isolation + runtime-set watcher kept.

* fix(daemon-ws): WS RPC disconnect-race panic + batch stale-comment-plan repair (MUL-4257)

Two PR #5193 review blockers:

1) WS RPC send-on-closed-channel race, both ends:
   - server: give each connection a cancelable ctx (cancelled on readPump
     teardown) and run the RPC handler under it, so a slow claim stops on
     disconnect; guard c.send with sendMu/sendClosed (trySend) so a late RPC
     response goroutine never writes to the closed channel. Heartbeat ack routed
     through the same guard.
   - daemon: wsRPCClient.deliver now sends under the mutex, serialized with
     attach(nil)'s close+delete, so a delivered response can't hit a channel
     the detach path just closed.
   - regressions (-race): daemon deliver-vs-detach; server
     disconnect-during-handler-response.

2) batch claim now runs the stale-comment-plan repair: extracted the
   per-runtime handler's repair (trigger deleted, only coalesced survive ->
   cancel + replay survivors) into shared repairStaleCommentPlanIfNeeded, called
   by both claim paths. Prevents the batch path (now the default poller) from
   finalizing+dispatching a task with no comment input and silently dropping the
   surviving user comment. Regression: batch omits the stale task, cancels it,
   and rebuilds the survivor into a new trigger plan.

* fix(daemon-ws): server-side RPC deadline + legacy claim fallback (MUL-4257)

Two review blockers:

1) WS RPC timeout/fallback (GPT-Boy): the daemon's WS wait didn't cancel
   server-side claim, so a slow WS claim could commit after the daemon fell
   back to HTTP, leaking dispatched tasks and breaking the free-slot bound.
   Fix: RPC envelope carries TimeoutMs; the server bounds the handler ctx by it
   (so ClaimTasksByRuntime's tx is cancelled/rolled back at the deadline), and
   the daemon waits budget + grace so a claim that committed before the deadline
   still reports back. A committed-then-unreported claim degrades to the same
   stale-reclaim safety net as HTTP, never a double effective claim. Regression:
   server-side TimeoutMs cancels the handler.

2) Backward compat (Terra-Boy): a new daemon against a server without the batch
   route (/api/daemon/tasks/claim 404) couldn't claim. Fix: ClaimTasksWSFirst
   falls back to the legacy per-runtime ClaimTask loop on a batch 404 and caches
   'batch unsupported' (reset on WS reconnect to re-probe after a server
   upgrade). Regression: server exposing only the legacy route.

* fix(daemon-ws): no double-claim on WS teardown/detach (MUL-4257)

Sol-Boy review blocker: on reconnect, teardown failed the pending RPC (→ HTTP
fallback) but then flushed the queued tasks.claim frame to the still-alive
socket, so the server committed the WS claim on top of the HTTP one — double
claim, WS batch orphaned to stale reclaim, breaking the free-slot bound.

- Teardown now closes the connection FIRST, so runWSWriter discards the queued
  RPC frame (write error path) instead of delivering it.
- A detach while a claim's frame is already in flight now returns a distinct
  errWSRPCUncertain; ClaimTasksWSFirst does NOT HTTP-fall-back on uncertain (the
  WS claim may have committed) — it skips the cycle and lets reclaim / the next
  poll recover. Genuine 'not sent' / timeout still fall back (safe: the
  server-side deadline guarantees no uncommitted claim by budget+grace).
- Regression: detach during an in-flight WS claim asserts zero HTTP claims
  (at most one path claims); plus the existing detach/deliver-race and
  server-timeout tests.

Co-authored-by: multica-agent <[email protected]>

* fix(daemon-ws): cancelable RPC frames close the backpressure double-claim (MUL-4257)

Sol-Boy review blocker: the client's response budget starts at enqueue, but
the socket write is async (10s write deadline). A backpressured writer could
hold a tasks.claim in the local queue past the client timeout — the daemon
HTTP-fell-back, then the writer woke and delivered the stale WS frame, so the
server committed it too: same free slots claimed twice. No detach occurs, so
the prior errWSRPCUncertain fix did not cover it.

- WS frames are now cancelable (wsOutbound{sent,canceled} under a mutex). The
  writer calls beginWrite() before WriteMessage and skips cancelled frames.
- On give-up (timeout / detach / ctx), Call cancels the queued frame: if it was
  still pending the cancel wins and the frame is guaranteed never delivered
  (errWSRPCUnavailable → safe HTTP fallback); if the writer already began
  sending it the cancel loses and the outcome is errWSRPCUncertain (no
  fallback). The decision is atomic, so at most one transport claims.

Tests: wsOutbound cancel-before-write vs write-before-cancel; Call timeout
cancels an unsent frame (writer then drops it) vs uncertain when already sent;
plus the updated detach and existing timeout/race tests.

* fix(batch-claim): return partial success instead of dropping committed claims (MUL-4257)

Sol-Boy review blocker: ClaimTasksForRuntimes reclaims (step 2) and claims per
agent (step 6) in independent transactions, but a step-4 candidate-SELECT error
or a mid-loop ClaimTask error did 'return nil, err' — discarding tasks already
committed as dispatched. The handler 500s; the daemon sees a definite (non-
uncertain) 500 and HTTP-falls-back, claiming a SECOND batch into the same free
slots while the first batch waits for stale reclaim — the double-claim this PR
removes.

- Both error paths now prefer partial success: if any task has already
  committed (claimed non-empty), return it (nil error) so the handler finalizes
  and returns 200; the errored candidates stay queued for the next poll. The
  remaining error is logged. Only a genuinely empty result still returns the
  error (safe: no committed claim to lose, HTTP fallback just re-fails).

Regression (internal/service, DB-backed, fault-injected):
- PartialSuccessOnSecondAgentClaimFailure: fail the 2nd ClaimTask's Begin →
  the first agent's committed task is returned, not dropped.
- PartialSuccessOnCandidateQueryFailureAfterReclaim: a stale dispatched task is
  reclaimed, then the candidate SELECT fails → the reclaimed task is returned.

Bohan Jiang 79c4589f7d fix(server): don't cancel active tasks when issue status → cancelled (#5328)
Moving an issue to `cancelled` used to auto-cancel every in-flight agent task
on that issue. Users have no expectation that clicking "cancel" stops running
agent runs, so this implicit coupling is removed from UpdateIssue and
BatchUpdateIssues. Deleting an issue still cancels its tasks (the owning row
disappears); a plain status change never does. Reassignment already didn't
cancel tasks (#4963 / MUL-4113), so this makes status-cancel consistent.

- Status-table-driven regression tests cover every active state the cancel
  query sweeps (queued / dispatched / running / waiting_local_directory /
  deferred) on both the single and batch paths.
- Updated the multica-working-on-issues skill (SKILL.md + source map) and
  corrected stale comments in task.go and agent.sql that described the removed
  coupling as current.

cb87dd106b feat(chat): task-owned direct-chat input batches + explicit no_response outcome (MUL-4351) (#5195)
* feat(chat): task-owned direct-chat input batches + explicit no_response outcome (MUL-4351)

Direct (web/mobile) chat no longer uses the last-assistant-row as an implicit
input cursor. Each direct send now owns an immutable input batch:

- agent_task_queue.chat_input_task_id makes a task the owner of the user
  messages it must consume; the send path creates the task + user message +
  attachment bindings + session touch in one transaction, and the daemon is
  notified only after commit. A claim reads exactly that batch, so a message
  that arrives mid-run belongs to the next task and is never absorbed.
- Auto-retry inherits the root input owner and is queued at a bumped priority,
  created inside FailTask's transaction so no newer chat task can jump ahead.
- CompleteTask writes exactly one assistant outcome inside the completion
  transaction: a normal message, or a visible no_response outcome (with a
  non-empty English fallback) when the final output is empty. The write failing
  rolls the completion back and the handler returns 5xx so the daemon retries;
  the status CAS keeps it idempotent. chat:done carries message_kind.
- Web/desktop/mobile render no_response as a localized 'no text reply' state
  (keeping the tool timeline), suppress Copy, keep it unread, and keep the
  session-list preview non-blank.
- Legacy/channel tasks (chat_input_task_id NULL) keep the trailing-message
  selector, so a rolling deploy never replays Slack/Lark history.

* fix(chat): scope no_response to direct tasks; don't cancel task on input read error (MUL-4351)

Addresses PR review (Niko):
- writeChatCompletionOutcome only writes a no_response row for task-owned
  direct tasks (chat_input_task_id set). Legacy/channel (Slack/Lark) tasks keep
  the prior behavior: empty output writes no assistant row, so chat:done carries
  empty content and the channel outbound silently drops it — the no_response
  fallback body never reaches an external channel.
- The daemon claim distinguishes a genuine zero-input batch from a failed
  input read: on ListChatInputMessages / ListChatMessages error it returns 5xx
  and preserves the dispatched task for redelivery instead of cancelling a valid
  task on a transient DB error.

75695a2e40 fix(comments): guarantee at-least-once processing of user comments (MUL-4195) (#5068)
* fix(comments): guarantee at-least-once processing of user comments (MUL-4195)

Consecutive comments on an issue were silently dropped: a new comment that
arrived while the agent already had a queued/dispatched task was discarded by
the HasPendingTaskForIssueAndAgent dedup, losing the user's follow-up
instruction with no visible trace. Comments — unlike chat — are deliberate,
addressed, persisted input and must never vanish.

This makes comment handling at-least-once while keeping concurrency bounded to
one run per (issue, agent):

- Merge, don't drop (PR1): a comment landing while a not-yet-started task
  exists is folded into that task — the prior trigger becomes a coalesced
  comment and the new one becomes the trigger, so a single run still covers
  every deliberate comment. Falls back to a fresh enqueue if the pending task
  was claimed mid-flight, so nothing is lost in the race.
- Completion reconciliation (PR2): on task completion, a member comment newer
  than the run's started_at schedules exactly one follow-up via the normal
  trigger pipeline. Loop-safe: member-authored only, capped by the existing
  per-(issue,agent) dedup, and terminating.
- Visibility (PR3): coalesced_comment_ids is surfaced on the task API and in
  the run prompt so the covered comments are explicit.

Migration 145 adds agent_task_queue.coalesced_comment_ids UUID[].

Tests: merge-not-drop preserves all three of a rapid burst and repoints the
trigger to the newest; reconciliation query gates on member/since; e2e
CompleteTask enqueues a follow-up for a mid-run member comment and does not for

* fix(comments): address review — originator gate, agent-scoped reconcile, cross-thread coalesced prompt (MUL-4195)

Resolves GPT-Boy's Request-changes review on PR #5068.

Must-fix #1 — merge no longer inherits a stale originator/runtime context.
MergeCommentIntoPendingTask now only folds a comment into a pending task
whose originator_user_id IS NOT DISTINCT FROM the new comment's originator.
runtime_mcp_overlay / runtime_connected_apps are a pure function of
(originator, agent) and the agent is fixed, so a matching originator keeps
the stored overlay/attribution valid; a differing originator (e.g. user B
commenting on a task originated by user A) matches no row and the caller
enqueues a fresh follow-up with B's own context instead of reusing A's.
trigger_summary is refreshed to the new trigger comment.

Must-fix #2 — completion reconcile no longer re-wakes unrelated agents.
reconcileCommentsOnCompletion computes the latest member comment's triggers
and keeps ONLY the agent that just completed, instead of fanning the comment
out through the full pipeline. An @-mention of agent B during agent A's run
is triggered once at creation time and is no longer replayed (double-run)
when A completes.

Should-fix #3 — coalesced-comment prompt no longer assumes a single thread.
The claim response now carries each folded comment's thread id / author /
created_at / content (CoalescedCommentData); the prompt embeds them directly
so the agent addresses cross-thread folded comments without the wrong
"they are in the triggering thread" hint. Old servers that ship only ids
fall back to an issue-wide fetch, still without the same-thread assumption.

Tests: TestMergeCommentIntoPendingTask_OriginatorGate (query gate),
TestCompleteTask_DoesNotReTriggerOtherAgentMentionedDuringRun (reconcile
scoping), TestBuildCommentPromptCoalescedCrossThread / IDsOnlyFallback
(prompt). Existing MUL-4195 suites still pass.

* fix(comments): close unique-index drop + dispatched-window race in comment coalescing (MUL-4195)

Second-round review follow-up on PR #5068.

Must-fix #1 — originator-mismatch no longer drops the comment.
The previous originator gate returned ErrNoRows on a different originator and
the caller fell through to a fresh enqueue, which collided with the
idx_one_pending_task_per_issue_agent unique index (one queued/dispatched task
per (issue, agent)) — silently dropping the second user's comment. Replaced
the gate with recompute-on-merge: MergeCommentIntoPendingTask now re-stamps
originator_user_id, runtime_mcp_overlay, runtime_connected_apps and
trigger_summary to the new comment's originator. A different member's comment
folds into the single coalescing run carrying the latest instruction's own
identity/overlay (no cross-user capability bleed, no drop, no collision).

Must-fix #2 — comment arriving in the claim→StartTask window is no longer lost.
Merge now targets only PRE-CLAIM states ('queued','deferred'); a
dispatched/running task is never a merge target, so a post-claim comment is
never falsely stamped into coalesced_comment_ids as "delivered". Completion
reconcile is re-anchored on dispatched_at (the moment the claim response is
built) instead of started_at, and sweeps ALL undelivered member comments since
that anchor — replaying each through the normal enqueue path so they coalesce
into one bounded, agent-scoped follow-up run. This covers the dispatch→start
window a started_at anchor missed.

Enqueue path: on a merge miss the caller no longer blindly fresh-enqueues
(which could collide with a dispatched sibling); it defers to the active
task's completion reconcile via HasActiveTaskForIssueAndAgent, and only
fresh-enqueues when no active task exists.

Tests: rewrote the query test to
TestMergeCommentIntoPendingTask_RecomputesOriginatorAndSkipsDispatched;
added TestConsecutiveCommentsDifferentOriginatorsFullEnqueuePath (full handler
enqueue path, two distinct originators) and
TestCompleteTask_ReconcilesDispatchedWindowComment (claim→start window). All
existing MUL-4195 handler/cmd-server/daemon/service suites still pass.

* fix(comments): catch pre-dispatch merge-race comment in completion reconcile (MUL-4195)

Third-round review follow-up on PR #5068.

Race: a member comment is created while the task is still queued, but its
merge loses the race to the daemon claiming the task (queued→dispatched). The
merge then finds no pre-claim row (ErrNoRows), the enqueue path defers to
reconcile — but the comment's created_at is BEFORE dispatched_at, so the
dispatched_at-anchored reconcile skipped it and the comment vanished with no
task coverage.

Fix: anchor completion reconcile on the task's created_at (which always
precedes dispatch) instead of a dispatch/start timestamp, and exclude the
run's DELIVERED SET — trigger_comment_id ∪ coalesced_comment_ids. Because
merges only ever touch pre-claim rows, that set is exactly what the claim
response carried, so any member comment created since the task was made that
is NOT in it was genuinely undelivered and earns a bounded follow-up. This
catches the pre-dispatch merge-race comment and the dispatch→start comment,
while never re-firing a comment that was delivered as a pre-claim coalesced
entry.

Test: TestCompleteTask_ReconcilesPreDispatchMergeRaceComment reproduces the
race (comment created pre-dispatch, task dispatched before merge, plus a
delivered coalesced comment) and asserts exactly one follow-up, triggered by
the race comment, with the delivered coalesced comment excluded. Existing
reconcile fixtures updated to set a realistic created_at (the production
invariant that created_at is the earliest task timestamp).

* fix(comments): merge only into the queued task, never a deferred fallback (MUL-4195)

Fourth-round review follow-up on PR #5068.

MergeCommentIntoPendingTask targeted status IN ('queued','deferred') ordered
by created_at DESC. When a (issue, agent) pair had both an older queued task
(the run about to be claimed) and a newer deferred assignee-fallback task, a
new comment merged into the deferred row instead of the queued one — so the
comment missed the imminent run and the deferred fallback could later promote
into a duplicate/conflicting run.

This merge is only ever reached when HasPendingTaskForIssueAndAgent matched a
queued/dispatched task (it never inspects deferred), so the coalescing target
must be the queued row. Restricted the merge target to status = 'queued'
(the unique index guarantees at most one). Deferred fallbacks keep their own
fire_at/promotion escalation lifecycle and are never a merge target.

Test: TestMergeCommentIntoPendingTask_TargetsQueuedNotDeferred seeds an older
queued task + a newer deferred fallback for the same (issue, agent), merges a
new comment, and asserts it lands on the queued task (trigger repointed, old
trigger coalesced) while the deferred fallback is left untouched.

a69d969fb1 fix(sweeper): gate running-task wall clock on runtime liveness (MUL-4107) (#4978)
The server-side running-task sweeper failed rows purely on `started_at >
now() - runningTimeoutSeconds` (2h30m). By its own comment the wall clock
is "mainly for runs whose daemon died without reporting" and "only needs
to sit generously above any realistic single run" — but the predicate
does not actually distinguish a healthy long-running task from an
orphaned one. On self-hosted deployments this kills multi-hour research
/ training runs mid-flight even though the daemon is still heartbeating
and the run is actively producing output.

The daemon side is intentionally unbounded (only inactivity watchdogs:
idle 30m, tool 2h); the server backstop was silently the only wall
clock. `FailStaleTasks` is now AND-gated on runtime liveness:

  * dispatched — unchanged; already excludes rows with a live
    `prepare_lease_expires_at` (renewed every 15s by the daemon between
    claim and StartTask).
  * running — new: excluded when the task's `agent_runtime` row is
    `online` AND `last_seen_at` is within the runtime stale window
    (staleThresholdSeconds = 150s, the same signal
    sweepStaleRuntimes already uses).

Healthy long-running tasks on live daemons are no longer killed by the
wall clock. The daemon-dead case remains primarily handled by
sweepStaleRuntimes in the same tick (Redis LivenessStore + DB stale +
FailTasksForOfflineRuntimes); the wall-clock branch is now a defensive
backstop for the pathological case where a runtime row lingers online
with a stale DB heartbeat for longer than the wall clock. `runtime_id
IS NULL` is treated as "not proving liveness" so the wall clock still
fires on that (rare / historical) shape.

The 2h30m default is unchanged — this is a gate, not a threshold
change. Tests updated: 4 existing running-task tests now age out the
runtime so they still exercise the wall clock; 2 new tests cover both
new invariants (healthy runtime → skipped; stale runtime → still
killed).

* feat(composio): server-side connect flow + connections REST (Notion MVP) (MUL-3720)

Compose the merged server/pkg/composio SDK into a user-facing connection
manager: signed-state connect handshake, local user_composio_connection
mirror, idempotent disconnect, and a per-user MCP session helper (not yet
wired into task dispatch).

- migration 127_user_composio_connection (no FK/cascade, per DB rules)
- sqlc queries: upsert (idempotent on user_id+connected_account_id), list
  active, owner-scoped get, mark revoked
- internal/integrations/composio: signed HMAC-SHA256 state, BeginConnect,
  CompleteCallback (idempotent upsert), ListConnections, Disconnect
  (upstream 404 = idempotent success), CreateMCPSession (no-op when empty,
  pins connected_accounts per toolkit), CallbackRedirect
- REST handlers under /api/integrations/composio (user-scoped, 503 when
  COMPOSIO_API_KEY unset): connect/init, callback (302), connections list,
  delete
- router wiring gated by COMPOSIO_API_KEY; COMPOSIO_AUTH_CONFIGS_JSON maps
  toolkit->auth_config (MVP: notion); state secret from COMPOSIO_STATE_SECRET
  or derived from JWT_SECRET; callback base from COMPOSIO_CALLBACK_BASE_URL
  or MULTICA_PUBLIC_URL
- tests: state (expire/tamper/wrong-secret), service (mapping, callback
  idempotency, non-success, disconnect owner/404 idempotency, MCP pin),

* fix(composio): bind callback account to user + idempotent revoked disconnect (MUL-3720)

Address PR 4608 review (CHANGES_REQUESTED):

- callback: verify connected_account_id with Composio before mirroring it.
  The signed state only proved user/toolkit/exp, so a valid state paired with
  a tampered connected_account_id would be written verbatim. CompleteCallback
  now calls ListConnectedAccounts and fails closed (ErrAccountVerification)
  unless the account belongs to the state's user (composio_user_id == multica
  user id) and was created under the toolkit's auth config. No row is written
  on mismatch / unknown account / upstream error.

- disconnect: short-circuit to a no-op when the local row is already revoked,
  before touching upstream. Previously a second DELETE re-hit Composio and a
  non-404 upstream error surfaced as a 502, breaking the 204-idempotent
  contract.

- CreateMCPSession: document the v1 single-active-connection-per-(user,toolkit)
  constraint and make duplicate selection deterministic (newest-wins, rows are
  connected_at DESC) instead of order-dependent map overwrite. Stage 3 owns the
  real single-account-enforcement vs multi-account-shape decision.

Tests: tampered/wrong-auth-config/unknown-account callback rejection, revoked-row
disconnect no-op (asserts upstream not re-hit). composio pkg 85% coverage; all
green.

* feat(composio): list all toolkits + dynamic auth-config resolution (MUL-3720)

Yushen's follow-up to the Notion MVP: surface the full Composio toolkit
catalog, render it in Settings, and drop the static env mapping in favor of
dynamic auth-config discovery.

Config correctness (per Composio docs):
- Remove COMPOSIO_AUTH_CONFIGS_JSON entirely. The toolkit→auth_config mapping
  is now resolved at request time from the project's /auth_configs (cached,
  5-min TTL), so enabling a toolkit is a dashboard action, not a redeploy.
- Do NOT add COMPOSIO_PROJECT_ID. The project API key (x-api-key) authenticates
  to exactly one project; the project is resolved from the key. Only org-level
  endpoints use x-org-api-key, which this integration never calls.

Backend:
- SDK: server/pkg/composio/auth_configs.go — ListAuthConfigs (toolkit_slug,
  is_composio_managed, show_disabled, limit, cursor).
- service: dynamic resolver (authConfigMap cache; betterAuthConfig prefers a
  custom/white-label config over Composio-managed, newest wins); BeginConnect
  and CompleteCallback resolve via it; ListToolkits fetches the full catalog
  (paginated, capped) annotated with connectable = has an enabled auth config,
  connectable-first ordering.
- handler + route: GET /api/integrations/composio/toolkits (user-scoped, 503
  when COMPOSIO_API_KEY unset) returning slug/name/logo/category/connectable.

Frontend:
- core: ComposioToolkit/ComposioConnection types, api client methods, and
  composio query options (@multica/core/composio).
- views: Settings → Integrations now has a Composio section rendering every
  toolkit as a card with search. Connect is gated on `connectable`;
  non-connectable toolkits show a muted "not configured" hint instead of a
  dead button. Connected toolkits show a badge + Disconnect (with confirm).
- i18n: composio block added to en/zh-Hans/ja/ko settings.

Tests: SDK + service (dynamic resolution, custom-over-managed preference,
connectable flag, resolver-error soft-degrade) and handler toolkits endpoint;
composio pkg 85.7% coverage. go build/vet/gofmt clean; core+views typecheck,
core+views lint, and core tests (691) all green.

* fix(composio): close cross-toolkit callback fail-open by signing auth_config_id into state (MUL-3720)

Re-review blocker: CompleteCallback resolved the toolkit's auth config at
callback time and ignored a resolve error/empty result, while
verifyAccountOwnership skipped the auth-config comparison when the expected
value was empty. A user could then pass another toolkit's connected_account_id
into this toolkit's callback — the owner check passed and it was written under
the wrong toolkit_slug/account binding.

Fix: the auth_config_id is already resolved in BeginConnect (before the state
is signed), so sign it into the state and compare it exactly at callback. No
re-resolve, no fail-open. verifyAccountOwnership now fails closed when the
expected auth config is empty (rejects instead of skipping) and requires an
exact match — closing the cross-toolkit binding gap.

Tests: state round-trips auth_config_id; BeginConnect signs it; callback
rejects wrong/cross-toolkit auth config and an empty (no-mapping) auth config
fails closed. composio pkg 85.2% coverage, all green.

Frontend (non-blocking): the Composio settings tab now surfaces an error when
the connections query fails instead of silently rendering everything as
unconnected.

* fix(composio): hide Settings section entirely when integration unconfigured (MUL-3720)

Decision (option 2, hide-then-merge): don't show a card that leaks the internal
COMPOSIO_API_KEY env-var name to every end user. IntegrationsTab now gates the
whole Composio section (heading + body) on the toolkits query — a 503 means the
key is unset, so the section is withheld instead of rendering the not-configured
card. Admin-only setup guidance is a later, role-gated affordance.

Removed the notConfigured card (and now-unused ApiError import) from
ComposioTab; it only mounts when configured. views typecheck + lint clean.

Composio 302-redirects the browser to /api/integrations/composio/callback
at the end of the OAuth flow, but PR #4608 mounted it inside the cookie-auth
middleware group. When the session cookie is absent (expired session,
SameSite=Strict / Safari ITP, private window, self-hosted callback subdomain)
the Auth middleware returned a hard 401 and a JSON blob instead of the
settings redirect, breaking the flow.

Identity never came from the cookie anyway: it is carried by the HMAC-signed
state param that CompleteCallback verifies (signature, expiry, replay) and
cross-checked by verifyAccountOwnership; h.Composio == nil still 503s. So the
callback is registered alongside the other public OAuth/webhook routes; the
other four composio endpoints stay session-gated.

* feat(composio): inject MCP overlay into agent runtime at task dispatch (MUL-3721) (#4704)

Stage 3 of the Composio epic. Wires the per-user Composio MCP session into
every agent task so the agent process sees the initiator's connected tools
without any prompt-time plumbing.

Server side
  - Migration 128 adds agent_task_queue.runtime_mcp_overlay JSONB plus a
    BEFORE-UPDATE trigger that wipes the column on any transition into a
    terminal status (completed / failed / cancelled). A trigger is the single
    source of truth — future queries that flip status cannot bypass it.
  - composio.Service.BuildTaskOverlay(userID) reuses CreateMCPSession and
    emits the Claude-style { mcpServers: { composio: { type: http, url,
    headers } } } shape the daemon's existing sidecar generators consume.
    Returns (nil, nil) on zero active connections so we never burn a
    Composio session for a user with nothing to call.
  - TaskService grows a Composio ComposioOverlayBuilder seam, wired in
    router.go after composiointeg.NewService succeeds. Five enqueue paths
    (issue / mention / quick-create / chat / auto-retry) attach the overlay
    after CreateAgentTask returns and before the daemon is notified — so
    every claim reads a settled row, with no second daemon hop. Best-effort:
    a builder failure logs and proceeds with no overlay.
  - resolveInitiatorFromTriggerComment derives the initiator user from the
    trigger comment when it was authored by a member. Agent-authored
    triggers are not treated as initiators (their connected-apps view is
    empty by construction).

Daemon side
  - handler/daemon.go claim path merges task.runtime_mcp_overlay onto
    agent.mcp_config via mergeMCPOverlay before populating
    TaskAgentData.McpConfig. Overlay wins on server-name collisions
    because it carries the live user-scoped session URL. Errors fall back
    to the agent config unchanged — a bad overlay must not surprise-disable
    saved MCP tools. The existing execenv sidecar generators (cursor /
    codex / openclaw / opencode / hermes-kiro) need no changes: they keep
    consuming the merged result through TaskAgentData.McpConfig.

Tests
  - 9 merge cases (mcp_overlay_test): both-nil short-circuit, agent-only
    pass-through, overlay-only canonicalization, two-side merge, name
    collision (overlay wins), top-level key preservation, malformed agent
    fallback, malformed overlay fallback, non-object server rejection.
  - 4 dispatch cases (composio): zero-connections returns nil without
    CreateSession, happy-path emits the right shape with the right user
    id, empty-URL defensive branch, SDK error surfacing.
  - 4 TaskService helper cases: nil Composio is a no-op (Queries-safe),
    invalid initiator does not call the builder, nil overlay skips the
    UPDATE, builder error swallowed without panic.
  - Migration 128 verified to roll up + down + up cleanly against the test
    database.

Out of scope (deferred): assignment-triggered enqueue paths with no
trigger comment get no overlay attached today (no initiator UUID flows
through enqueueIssueTask in that case). Retry paths recompute the overlay
fresh from the parent's initiator_user_id instead of inheriting the bearer
from the parent row, so a stale token can never resurface on a retry.

* feat(composio): per-agent allowlist + originator-scoped MCP overlay (MUL-3869) (#4736)

* feat(composio): per-agent allowlist + originator-scoped MCP overlay (MUL-3869)

Stage 3.1 of the Composio epic (MUL-3721 parent). PR #4704 wired in the
runtime_mcp_overlay column and a per-task dispatch hook; this change
inverts the default from "all-on" to opt-in and locks the overlay to the
agent owner's own connected apps:

- Agents carry composio_toolkit_allowlist TEXT[]. NULL or [] => no MCP.
  Owner-only read/write; non-owner GET/PUT silently redacts/drops the
  field (same shape as mcp_config).
- agent_task_queue carries originator_user_id UUID. Set from the
  top-of-chain HUMAN at every enqueue path:
    * issue/mention comment by member  -> author_id
    * issue/mention comment by agent   -> inherit via comment.source_task_id
                                          -> parent task originator_user_id
    * quick-create                     -> requester_id
    * chat                             -> initiator_user_id
    * retry                            -> SQL-inherited from parent row
    * autopilot                        -> NULL (system-driven)
- BuildTaskOverlay (composio dispatch) now takes (ctx, originatorUserID,
  agent) and short-circuits on five gates: invalid originator,
  originator != agent.owner_id, empty allowlist, empty intersection of
  allowlist ∩ active connections, defensive empty session URL. Composio
  CreateSession is called with BOTH `toolkits.slugs` (the intersection)
  AND `connected_accounts` (the pinned account ids), narrowing the
  tool-router twice.
- The originator-vs-owner gate closes the agent-fanout privacy hole: any
  workspace member who can @-mention a public agent used to project the
  owner's connected apps into their run. Now the overlay only mounts
  when the human at the top of the chain IS the agent owner.

Tests:
- dispatch_test.go covers all 5 gates plus uppercase/whitespace slug
  normalisation.
- task_runtime_mcp_overlay_test.go covers the no-op gates of the new
  applyRuntimeMCPOverlay signature.
- agent_composio_allowlist_test.go (handler): owner roundtrip
  (list/empty/null), workspace-admin silent-drop, owner-only GET
  visibility, pure normaliseComposioToolkitAllowlist.
- resolve_originator_test.go (service, DB-backed): member-authored,
  agent-authored inherits via comment.source_task_id, invalid id.

Migration 129 up/down/up verified against docker postgres.

* feat(views): creator-only MCP tab for per-agent Composio allowlist (MUL-3870) (#4743)

Stage 3.2 frontend on top of the Stage 3.1 backend (MUL-3869, 4708dba97).
Adds an agent-detail tab that lets the agent owner pick which of their own
active Composio connections this agent may mount as MCP servers, writing the
selection to agent.composio_toolkit_allowlist via the existing PUT /api/agents.

- core/types: composio_toolkit_allowlist (+ _redacted) on Agent; tri-state
  composio_toolkit_allowlist on UpdateAgentRequest (omit/no-change, null/clear,
  array/replace), matching the backend contract.
- core/agents: useUpdateAgentAllowlist - optimistic mutation hook (patches the
  cached workspace agent list, rolls back on error, invalidates on settle).
- views: AgentMcpTab renders the owner's active connections as checkboxes;
  empty state links to Settings -> Integrations; defensive redacted state.
- views: wired into AgentOverviewPane as tab "composio_mcp", labeled "MCP Apps"
  to disambiguate from the existing raw-JSON "MCP" (mcp_config) tab. The entry
  is gated to the creator (currentUserId === agent.owner_id), matching the
  backend's owner-only read/write of the allowlist.
- i18n: tabs.composio_mcp + tab_body.composio_mcp.* in en/ja/ko/zh-Hans.
- tests: agent-mcp-tab.test.tsx (gating, toggle->allowlist body, active-only,
  empty, redacted); e2e/agent-mcp.spec.ts (creator sees tab + PUT body,
  non-creator hidden) with Composio + agent endpoints mocked at the boundary.

Note: the product spec says "creator"; the schema has no creator_id - the
backend gate and redaction are keyed on owner_id, so the tab uses owner_id.

Follow-up on PR #4844: public_to now supports selecting MULTIPLE, MIXED
targets on one agent (e.g. Public to workspace + specific people + team),
with canInvokeAgent admitting on ANY matching target (OR).

- Frontend AccessPicker: reworked from a single exclusive kind into a
  stackable multi-select — an "Everyone in workspace" toggle, a member
  multi-select checklist, and a (disabled, v1) team placeholder can be
  combined freely. Emits the full union of selected targets; empty union
  collapses to Private. Existing team targets are preserved across saves.
  Added the access.public_group locale string (en/zh-Hans/ja/ko).
- Backend already supported this (agent_invocation_target is multi-row per
  agent; create/update take a target ARRAY and batch-replace the whole
  allow-list; canInvokeAgent OR-matches). Added tests to lock it in:
  mixed member+team targets, overlapping-member batch replace, and
  workspace+member stacking then narrowing.

* fix(agents): address review on invocation permission (MUL-3963)

张大彪 review on PR #4844 — three blockers + product ruling + nits:

1. Migration 130: drop the FK/cascade on agent_invocation_target
   (agent_id, created_by) per the Multica no-FK rule; relationships are now
   maintained in the app layer (matching MUL-3515 §4). Added
   DeleteAgentInvocationTargetsByArchivedRuntimeAgents and call it before
   DeleteArchivedAgentsByRuntime in all three runtime-delete paths
   (runtime.go x2, runtime_profile.go) so hard-deleting agents can't orphan
   target rows.
2. revokeAndRemoveMember: prune the leaving member's member-target grants
   (DeleteAgentInvocationTargetsByMember) in the same tx as the member-row
   delete, so a re-invited user can't reclaim a stale invocation grant.
3. Empty public_to is a phantom — parsePermissionInput now normalises a
   public_to with no resolvable targets to a single workspace target, so
   `--permission-mode public_to` alone (and any empty target array) means
   "public to workspace" instead of "shared but nobody can run it".

Product ruling: the system/no-human-originator → workspace-target path in
canInvokeAgent is a deliberate, documented exception (webhook/system/
workspace-wide automation); member/team targets still fail closed without a
resolved originator. Documented in code + locked with a test.

Nits: refreshed the stale "originator must be owner" comments — models.go
(via migration 130 COMMENT ON COLUMN + sqlc regen for composio_toolkit_allowlist
and originator_user_id) and agent-mcp-tab.tsx — to the owner-connection +
invocation-permission rules.

Tests: member remove/re-add regression, system workspace exception + member
fail-closed, empty public_to → workspace (plus the earlier mixed/overlap/
batch-replace suite). Migration 130 applied to the test DB; Go handler/service/
composio suites green; views typecheck clean.

* fix(agents): scope member invocation-target cleanup to one workspace (MUL-3963)

张大彪 3rd review — cross-workspace permission bug + comment nits:

- DeleteAgentInvocationTargetsByMember was a GLOBAL delete by user id, so
  removing a user from workspace A also wiped their member-target grants on
  agents in workspace B. Scoped it to a single workspace by joining through
  agent.workspace_id; revokeAndRemoveMember now passes (workspaceID, userID).
- Regression test TestRevokeMember_InvocationTargetCleanupIsWorkspaceScoped:
  same user allow-listed by agents in two workspaces; removal from one leaves
  the other workspace's target intact.
- Nits: refreshed the remaining stale "originator == agent.owner_id" /
  "owner-vs-originator" comments — CreateRetryTask (agent.sql, regenerated),
  and the AgentResponse allowlist doc + ListAgents/UpdateAgent redaction
  rationale in agent.go — to the owner-connection + invocation-permission rule.

Migration 130 applied to the test DB; Go handler/service/composio suites green;
go vet clean.

* fix(agents): agent access owner-only editable, read-only for others (MUL-3963) (#4853)

* fix(agents): make agent access owner-only editable, read-only for others (MUL-3963)

Interaction bug: a non-owner (incl. workspace admin) could open the AccessPicker
and set an agent public — the backend silently ignored it and the UI bounced
back to private. Access is owner-only, so non-owners must see a read-only state
and the backend must reject real changes explicitly.

Frontend:
- AccessPicker renders a static, non-interactive read-only state when the
  viewer is not the owner: the current access value + a lock affordance + a
  tooltip "Only the agent owner can change who can run this agent." No clickable
  trigger is rendered, so a non-owner can never open a control the backend would
  reject (the GitHub/Notion pattern for permission settings you can see but not
  edit). The editable multi-select picker is unchanged for the owner.
- agent-detail-inspector gates the picker on ownership specifically
  (currentUserId === agent.owner_id), NOT the general canEdit (which also admits
  admins, who may edit other fields but not access).
- New locale key access.owner_only_readonly (en/zh-Hans/ja/ko).

Backend:
- UpdateAgent now returns an explicit 403 when a non-owner submits a REAL
  permission change (permissionInputChangesAgent compares requested mode +
  target set against the persisted state); a no-op resubmit (admin PATCH-as-PUT
  echoing unchanged permission) is still tolerated so admin edits of other
  fields keep working. Replaces the previous silent-drop that caused the bounce.

Tests:
- access-picker.test.tsx: non-owner gets a non-interactive read-only display
  with the owner-only tooltip; owner gets an interactive picker; owner can pick
  a member and stack workspace + member.
- TestUpdateAgent_AccessChangeIsOwnerOnly: admin real change → 403; admin no-op
  resubmit → 200; admin editing other fields → 200; owner change → 200.

Incidental: fixed a pre-existing base typecheck break in
slash-command-suggestion.test.tsx (stray `signal` arg not in the suggestion
items type) that otherwise fails the whole @multica/views typecheck.

* fix(agents): compare legacy visibility, not expanded permission, for no-op detection (MUL-3963)

PR #4853 review: permissionInputChangesAgent expanded a legacy-only
visibility:"private" into a real private permission and compared it against the
agent's actual permission. A member-only public_to agent derives legacy
visibility "private", so an admin PATCH-as-PUT echoing visibility:"private"
while editing another field was misread as a public_to→private downgrade and
rejected with 403 — contradicting the "unchanged permission no-op is allowed"
contract.

Fix (per review): when a request carries ONLY legacy `visibility` (no
permission_mode / invocation_targets), derive the agent's CURRENT legacy
visibility from its real targets and compare the legacy string values. Equal =
no-op (allowed); a real legacy change (e.g. "workspace") still returns 403.
Requests that carry permission_mode / invocation_targets keep the precise
mode+target comparison.

Regression test TestUpdateAgent_LegacyVisibilityNoOpForMemberOnlyPublicTo:
member-only public_to agent — admin submitting visibility:"private" + a
non-permission field → 200 with targets unchanged; admin submitting
visibility:"workspace" → 403.

Go handler/composio suites green; migration 130 applied; go vet clean.

AntoineandMultica Ops 4ed8f7478f fix(server): key reviewer-loop dedup on reviewed commit SHA (MUL-4003) (#4873)
The agent-task run-dedup keyed only on (issue_id, agent_id), so a
completed/pending verdict for commit A was silently reused to satisfy a
review request for a NEWER commit B pushed after A's run began — giving B
zero review coverage (nearly shipped an unreviewed commit; sibling of the
daemon disposition-loss bug in #4337).

Fix (no migration — reuses the existing context JSONB column):
- CreateAgentTask stamps the reviewed head_sha into the task's context.
- HasPendingTaskForIssueAndAgent(+ExcludingTriggerComment) now key dedup on
  that head_sha: a pending task only dedups a request carrying the SAME
  head. If HEAD advanced (or the pending task predates the stamp), dedup
  MISSES and a fresh review enqueues. Empty head_sha (no linked PR) falls
  back to the previous (issue_id, agent_id) key, so non-PR issues keep
  coalescing unchanged.
- head_sha resolves from the issue's linked PR via GetIssueReviewHeadSha
  (prefers open/draft, newest by pr_updated_at); ResolveIssueReviewSHA
  fails soft to '' so a github-table hiccup can never over-dedup a review
  out of existence.
- Threaded through all six dedup trigger sites (comment @mention + edit
  preview, issue-status, squad-leader assign, child-done agent + squad).

Issue-linked tasks never reach quick-create context parsing, so the key
rides harmlessly alongside. Adds DB-backed regression tests pinning:
advanced-head misses dedup, repush invalidates dedup, same-SHA still
dedups, and no-linked-PR legacy fallback (verified non-vacuous against the
pre-fix query).
