* feat(wecom): send the files an agent produced into the chat An agent that produced a file and answered in WeCom delivered only the sentence. `multica attachment upload` had already run, the object was in storage, and CompleteTask had bound the row to the assistant message — but nothing downstream of that bind knew how to reach a WeCom conversation, so the file stopped there. The user read "here is the forecast" and got no forecast, with no error anywhere to explain it. Worse when the agent said nothing at all: an empty completion with a file bound to it returned early, so the artifact was thrown away silently. This adds the last hop. media_upload.go carries a file up the long connection — WeCom has no REST endpoint for this, so it goes as aibot_upload_media_init / _chunk / _finish over the same socket, and all three read their verdict through the request() layer #6590 generalized. outbound_media.go is the caller: after the answer is out, it reads the bound attachment out of object storage, decides what to call it, and pushes it in as its own message. Three decisions worth naming. The answer goes first and the file never blocks it. An upload is megabytes and round trips and it can fail; delivery runs after the words are out, on its own goroutine and a budget of its own, and its worst outcome is one extra line saying a file did not make it. A lost ack and a refusal are opposite failures. A chunk whose verdict never came is offered once more — the protocol makes re-sending idempotent, and losing one slice of a hundred must not cost the file. A chunk the server refused is not, because the refusal is its answer and will be its answer again. The push of the finished media follows the same rule in reverse: a timeout is reported as-is rather than retried, because the same media_id sent twice puts the file on the user's screen twice with nothing to undo. WeCom validates bytes against the msgtype, so what to call a file is a decision. A kind past its ceiling is demoted to a plain file rather than sent and refused — a card the user can open beats a photo the server rejected. WithAttachments is what turns this on, and router.go passes it only when the deployment configured object storage. Without it the adapter behaves exactly as it did before. * fix(daemon): stop telling a WeCom agent its conversation is text-only The per-turn chat prompt and the runtime brief both decided file delivery by asking "is there a channel at all". Any non-empty ChatChannelType got the text-only paragraph: `attachment upload` does not apply here, describe the file in words, never write its local path. That was true of every IM channel when it was written, and it stopped being true for WeCom, whose adapter now reads the bound attachment out of object storage and sends it into the room. So an agent on WeCom was instructed not to use the one command that would have delivered its file. The capability shipped and the agent was told it did not exist. The delivery question is per-adapter, not "is there a channel", and ChannelCarriesFiles is where that answer now lives. Both call sites branch three ways instead of two. The new copy is deliberately built from main's existing web-chat branch rather than written fresh. Both open on the same clause — "To include a file or image you produced in your reply, run `multica attachment upload <local-path>`" — and diverge exactly where the platforms diverge: web chat says the file "appears as an attachment card below it" and offers a markdown snippet to place it inline; WeCom says Multica "sends it into the WeCom conversation as a separate message right after your text" and that "there is no way to place it inline". That last clause is the one worth having. An agent told only that files work here writes "see the chart below" and then nothing appears below, because the long connection has no msg_item and a picture cannot be embedded in the reply. Slack and Lark keep their existing text-only wording untouched. Two comments are rewritten rather than carried over, because they asserted the binary the same commit falsifies — "keys off 'is there a channel at all'" in prompt.go, and "any non-empty channel type means the reply leaves Multica for an external IM platform, where `attachment upload` has nothing to bind to" in the brief. A comment that contradicts the code beneath it is worse than none. ChannelCarriesFiles names every channel type this package knows rather than leaving Slack and Lark to the default, so a fourth adapter surfaces here as a decision to make. An unrecognized type answers false: the agent is told to describe its file in words, and the worst case is a deliverable that could have been sent was not. False the other way would have it promise a delivery nothing performs. * fix(wecom): stop claiming more certainty than the system has Three review blockers, one shape: a promise made in one place that another place cannot keep. Capability came from the channel type. The daemon answered "this conversation takes files" from `chat_channel_type == "wecom"`, but the last hop only exists where the server wired object storage — so a WeCom deployment without storage had its agents told to send files nothing would carry, and a new daemon on an older server inferred a capability that build has no code for. The server now answers it per turn on the claim (`chat_channel_delivers_files`), declared by the same `if store != nil` branch that gives the adapter the storage, and absent/false everywhere else. Upload limits came from the framing. 50 MB is what 100 chunks of 512 KB can describe; WeCom's own OpenClaw plugin puts the hard file ceiling at 20 MiB, so that is now the cap, enforced against the attachment's recorded size before any byte is read. Concurrency was a fixed 4 regardless of size; WeCom's own SDK steps it down — all at once up to 4 chunks, 3 up to 10, 2 past that, because their backend answers a burst of chunks on a large upload with a system error. Failure handling had two words for three outcomes. A send whose ack never came was reported as a definite failure although the file may well be in the chat, and the local failures — a full pending queue, a slot wait that expired, a lookup that errored — were reported to nobody at all. There are now three states: delivered says nothing, definitely_failed keeps the definite wording, and unknown gets wording that holds either way and is never resent, since a duplicate file cannot be taken back. The attachment lookup moved ahead of the rationing so a shed delivery knows there was a file to apologise for, and a turn with nothing attached still says nothing. * fix(wecom): bound the attachment lookup, and stop calling an attempted write a failure Two gates, not one better place for one gate. The pending counter is claimed after the lookup so a shed can name a real file, which is also why it cannot bound the lookup: at the point it would have to be claimed, whether the turn carries a file is exactly what is not yet known. admitAttachmentDelivery is claimed before the spawn and bounds the goroutines and the queries they run. Its cap is twice the pending cap, so a backlog meets the honest post-lookup shed first and only reaches the silent one when the system is already well past it. A refusal there is logged and not spoken — telling a user their file was dropped on a turn that may have carried none is the false alarm the post-lookup gate exists to prevent. Separately, a WebSocket write error stopped being read as proof of non-delivery. wsSender.write already distinguished the stages for tracing; it now carries that out in the error. Past WriteMessage the frame may be at the peer — a half-closed connection reports "broken pipe" to the writer for bytes the reader has — so those classify as unknown and are never resent. What fails before the write is provably local and stays definite. Tests drive the real path rather than the counters: one blocks the lookup, submits past the cap, and counts the goroutines and queries that actually happen; one hands the frame to a connection that records it and then fails. Both fail without the change. fakeObjectStore takes a lock, because it is no longer only ever driven inline. * docs(wecom): cite the size limits to WeCom's docs, not a third-party constant The upload ceilings were sourced to Tencent's OpenClaw plugin. That file carries the right numbers but cites nothing itself, so it corroborates rather than establishes them. WeCom documents all four on aibot_upload_media_init's body.total_size row, and repeats them on the classic media upload API. Point at those. * fix(wecom): drop the two media helpers #6605 brought in ahead of this branch This branch carried its own cleanShort filename and extension helpers because nothing else in the package had them when it was written. #6605 has since merged, and it brings both — so the package now declares each twice and does not compile against current main. GitHub still reported the branch mergeable and CI was green, because both were measured against a main that predated that merge by six hours. Upstream's copies are the ones to keep: its cleanMediaFilename also strips control characters out of a name, and its mediaExtension drops a charset parameter before matching. Neither of those was in the copies here. * fix(daemon): keep the file-delivery verdict out of the cached brief chat_channel_delivers_files arrives on every claim and answers a deployment question: does this server carry a file the last hop into the room. Upgrading a server so it starts sending the field, or turning object storage on or off, flips it under a chat session that is already running — and the brief branched on it, so one resumed session rendered two different briefs. The brief is the prompt-cache prefix (MUL-5377), which makes that a miss on every turn after the flip. The two rows in the delivery test asserting different briefs for the two verdicts were the exposure written down: they are what one session sees in sequence. The brief's channel-backed chat copy now names the platform and says the answer is stated per turn. It holds on either verdict and contradicts neither. The verdict has a home already — the per-turn chat prompt, whose branch was correct and is untouched — and that message is emitted on every turn, so nothing is lost by the brief declining to answer. Slack and Lark take the same copy. Scoping it to WeCom would put a channel-type decision back into the brief, which is what ChannelCarriesFiles exists to prevent, and would hardcode a denial a server-side change can falsify. Coverage moves rather than goes. TestBriefByteIdenticalAcrossRunsForEveryKind gains a WeCom kind and a variant that flips the field; both fail without this change, and the existing Slack kind fails on the variant too. The delivery test's two WeCom rows assert the inverse property now — one brief for both verdicts — and the upload/describe split they used to hold is pinned by TestBuildChatPromptTwoLayerChannelPolicy on the per-turn prompt, which has covered both branches all along. * docs(wecom): correct what the admitted cap implies, and note that delivery cannot answer back The comment on the two counters said reaching the admitted cap means the pending cap is full and as many turns again are still in their lookup. It does not. Admission is held for a goroutine's whole life, including turns whose lookup finds no file and which therefore never claim a pending slot — TestDeliverAttachments_AdmissionBoundsTheLookupStage fills admission with pending at zero. The two-counter split and the ordering it buys are unchanged: a backlog of file-carrying turns still meets the honest post-lookup shed first. The package doc gains the fact that an agent cannot learn its delivery was refused. `multica attachment upload` returns once the object is in storage and bound to the reply, while the send into the room runs on EventChatDone, after the run has ended, so everything the adapter knows about a failed delivery goes to the person in the chat and to nobody else.

|
||
// requirements ("CI must pass before merge"), so the section now says
|
||
// branch protection is not the agent's acceptance criterion, and gives
|
||
// the replacement hand-off phrasing so the urge to prove quality lands
|
||
// on local test output plus a PR link instead of on a wait.
|
||
//
|

// The ban is scoped, not absolute: an explicitly requested CI result is
|

// still reachable, and it names the one executable way to collect it

// handoff contract (lifecycle independence, durable logs, cleanup handle);
|
||
// how to detach is the Local Dev Environment skill's concern, not the brief's.
|
||
//
|
