-- name: LockPluginPackageKey :exec
-- Serializes publish, install and delete for one (workspace, plugin key).

-- Relationships are application-owned by repository policy, so there are no
-- foreign keys to make "this version still exists" true across statements.
-- Without this lock the interleaving `delete counts 0 installs` → `install
-- reads the version` → `delete commits` → `install commits` leaves an
-- installation pointing at a version that no longer exists, and its panel 404s
-- forever with nothing in the product able to explain why.
--
-- Keyed on the plugin key rather than the package id because publish has no
-- package id yet — the row it would lock is the one it may be about to create.
