Tail of #244. Three items:
1. Coverage-gate (main). develop had no coverage tooling at all. Added
@vitest/coverage-v8@4.1.6 (pinned to the vitest already in use) to the three
vitest packages — git-sync, editor-ext (which also gains its missing direct
`vitest` devDep), apps/client — and enabled v8 coverage with per-package
thresholds (no root vitest config exists, so per-package is the only
meaningful scope). v8 provider is chosen deliberately: istanbul broke on the
ESM `@docmost/editor-ext` barrel; v8 collects native runtime coverage and
never re-parses ESM. `enabled: true` wires the gate into the plain `test`
script, so `pnpm -r test` (the CI entrypoint) enforces it without a manual
`--coverage`. Thresholds set ~4-5 pts below measured current coverage so the
gate PASSES today and FAILS on regression (verified: forcing lines=95 on
editor-ext exits 1). `all: false` — coverage counts test-touched files;
documented in the configs (with `all: true` the many untested type/barrel
files would sink the % and make the gate meaningless).
Measured→threshold (S/B/F/L): git-sync 91.78/79.16/76.76/92.46 → 88/75/72/88;
editor-ext 58.58/48.1/64.96/58.91 → 54/44/60/54; client 59.93/58/48.47/59.39
→ 55/53/44/55. All exit 0.
2. acceptInvitation atomicity int-spec. New
apps/server/test/integration/workspace-accept-invitation-atomicity.int-spec.ts
(+ createDefaultGroup/createInvitation seeders in test/integration/db.ts per
its convention). Wires the real WorkspaceInvitationService with real
User/Group/GroupUser repos against the test Kysely, stubbing only the
post-commit collaborators. Asserts the invariant protected by
users_email_workspace_id_unique: (a) two CONCURRENT accepts → exactly one
fulfilled, one BadRequestException('Invitation already accepted'), membership
count == 1, invitation consumed; (b) repeated sequential accept → still one
membership; (c) the survivor is in the workspace default group (whole-tx, no
torn state). Ran against real Postgres+Redis: 3/3 pass.
3. turn-end decision unit test. `decideTurnEnd` does not exist as a symbol; the
turn-end logic lives in chat-thread.tsx's onFinish handler. Added a focused
block to the existing chat-thread.test.tsx (matching its hoisted-mock style):
clean finish → flush queued (continue); abort/disconnect/error → queue
preserved (end) with the correct notice; parent notified on every terminal
outcome. 8 passed (3 existing + 5 new).
Verified: git-sync 712, editor-ext 247, client 888 (all with the gate, exit 0);
int-spec 3/3 (real Postgres); tsc --noEmit clean for client + server;
pnpm install --frozen-lockfile consistent (lockfile additive).
