 ```
 
+`pnpm doctor` is the setup completion check: `bash scripts/setup.sh` installs dependencies and writes placeholder `.env.local` values, but "installed" is not "working." Doctor fails loudly (nonzero exit) on missing or placeholder env, verifies the Clerk publishable key actually decodes to a real host, and probes both Canary and the running app's `/api/health` -- warning (not failing) when the app or Canary aren't reachable yet, since that's expected before `pnpm dev` is running.
+
 Keep `NEXT_PUBLIC_CONVEX_URL` pointed at the same backend you're running. For local development, use `http://localhost:8187`; if you target a remote Convex deployment, local Dagger now syncs the active Convex dev backend before auth-heavy E2E runs so frontend/backend validators stay aligned.

+# Convex Schema Migrations: Expand, Migrate, Contract
+
+Convex validates `convex/schema.ts` against every row already in the table at
+push time. That single fact is the whole reason this doc exists: you cannot
+remove a field from the schema until every row has already stopped depending
+on it, and you cannot depend on "the migration will run in this same deploy"
+because the schema push and the migration run are not atomic with each
+other — the schema push happens first, and it can fail on data the migration
+hasn't touched yet.
+
+## The 2026-07-04 incident
+
+PR #298 ("drop legacy mode columns") added `migrations.dropLegacyModeColumns`
+and removed the `mode`/`selectedMode` fields from `convex/schema.ts` **in the
+same commit**. `git show 684de32 -- convex/schema.ts convex/migrations.ts`
+is the exact diff. The result:
+
+1. Convex push validated the new (contracted) schema against production data.
+2. 153 `games` rows and 1 `rooms` row still had `mode`/`selectedMode` set —
+   the migration that would have cleared them had never run against
+   production, because it could only run _through_ a successful deploy.
+3. Every deploy wedged, including the unrelated P0 CSP hotfix (linejam-912)
+   that production needed immediately.
+4. Recovery required an operator to run the migration manually against
+   production, outside the normal deploy pipeline, before the schema push
+   could succeed.
+
+The gate that would have caught this (`scripts/ci/check-schema-migration-sequencing.mjs`,
+below) did not exist yet; it does now, and its regression test replays this
+exact diff.
+
+## The sequence
+
+Never contract schema in the same deploy that introduces its migration.
+Three separate, independently-deployable steps:
+
+1. **Expand.** Add the new field/shape alongside the old one. Schema keeps
+   accepting both. Ship and deploy.
+2. **Migrate.** Ship a migration (`convex/migrations.ts`, an
+   `internalMutation` invoked via `npx convex run`) that backfills/clears
+   data into the new shape. **Run it against production** and confirm it
+   completed (row counts, not just "the deploy succeeded").
+3. **Contract.** Only now, in a separate PR/deploy, remove the old
+   field from `convex/schema.ts`.
+
+Steps 2 and 3 must never land in the same change. Step 1 can sometimes merge
+with step 2 (adding a field and its backfill together is safe — nothing yet
+depends on the old field being gone).
+
+## The gate
+
+`scripts/ci/check-schema-migration-sequencing.mjs` runs in CI (`quality-gates`
+job, pull requests only — see `.github/workflows/ci.yml`) and diffs the PR
+against its base ref:
+
+- `convex/schema.ts`: any **removed** field-definition line
+  (`fieldName: v.something(...)`).
+- `convex/migrations.ts`: any **added** exported Convex function
+  (`export const name = internalMutation({ ... })` or `mutation`/
+  `internalAction`/`action`).
+
+If both are true in the same PR, the gate fails with the specific removed
+field(s) and added migration(s) named, and points here. It is a text-diff
+heuristic, not a schema-aware parser — deliberately, so it needs no build
+step and runs in milliseconds — and it only needs to catch the shape of this
+exact failure class, not every conceivable migration mistake. If migrations
+ever move out of the single `convex/migrations.ts` file, update
+`MIGRATIONS_FILE`/the glob in that script.
+
+**Known limitation** (found by a fresh-context critic reviewing this gate):
+because it only looks at `+` lines, a migration function _pre-scaffolded_ in
+an earlier PR (the `export const` line already exists, unchanged) and then
+filled in with its actual contraction logic in the same PR that also removes
+the schema field would not trip the `addedMigrations` match — the export
+line is unchanged context, not a new line. The gate also cannot know whether
+an _already-shipped_ migration was actually run against production before a
+later contraction PR merges; it only proves the two didn't land in the same
+diff, which is the invariant that actually burned us on 2026-07-04. Treat
+this as a heuristic tripwire for the exact known failure shape, not a
+guarantee against every sequencing mistake — code review is still the
+backstop.
+
+This is a **CI-only** check (it needs `git diff <base>...HEAD`, which
+requires the PR's base ref and enough history — the `quality-gates` job
+fetches both). It intentionally runs outside the Dagger containers the rest
+of `quality-gates` uses, because it operates on git history rather than the
+source tree, and containerizing a `git diff` buys nothing.
+
+## linejam-019 lesson (annotated same day)
+
+linejam-019 ("legacy mode column cleanup") is the card `dropLegacyModeColumns`
+shipped under. The lesson recorded on that card: schema contraction and its
+migration are two separate deploys, never one — see this doc for the
+enforcement mechanism.

 Canary itself treats generic signed webhooks as the stable product contract, so the responder should stay thin: verify, fetch context, store evidence, trigger the smoke harness, then hand off to follow-on agents.
+
+## Production Smoke Failure Wire (linejam-913)
+
+The `Production Smoke` workflow (`.github/workflows/prod-smoke.yml`) runs hourly and, before 2026-07-04, a red run just sat in the Actions tab: it failed hourly for ~15 hours before the operator found the outage by hand. The gate was working; nothing wired the red signal to a human or to BB triage.
+
+Two scripts close that wire, running as the last steps of the job regardless of outcome (`if: always()`):
+
+- `scripts/ops/count-consecutive-prod-smoke-failures.mjs` walks the workflow's recent completed-run history (via the GitHub REST API, `GITHUB_TOKEN`) to compute the consecutive-failure streak ending at the current run. A single blip does not escalate; only a genuine repeat does. On an API error it fails OPEN toward escalation rather than silence.
+- `scripts/ops/report-prod-smoke-status.mjs` reports the outcome to the `linejam-production-smoke` Canary TTL monitor (`expected_every_ms=3600000`, `grace_ms=1800000`, created via `POST /api/v1/monitors`) via `POST /api/v1/check-ins`:
+  - Success → `status: "ok"` (Canary's Up health state; resolves any open incident).
+  - Failure, streak < 2 → `status: "alive"` (still Up; recorded in the monitor's check-in history and the run's step summary, but does not open an incident).
+  - Failure, streak >= 2 → `status: "error"` (Canary maps `error` check-ins directly to its Down health state, which opens/holds a `health_transition` incident that BB triage and the bridge feed already consume — no linejam-side webhook or bridge-specific code needed).
+
+  Reuses the existing `NEXT_PUBLIC_CANARY_API_KEY`/`NEXT_PUBLIC_CANARY_ENDPOINT` repository secrets (already ingest-scoped for client-side error reporting); no new secret was provisioned.
+
+Live-verified end to end against the deployed monitor: a first simulated failure stayed `up`/`alive`; a second consecutive simulated failure flipped the monitor to `down` and opened `INC-bhg3g284flhp` (`signal_type: health_transition`); a simulated recovery run immediately resolved it. Query current state any time with:

+curl -fsS "$CANARY_ENDPOINT/api/v1/report?window=24h" -H "Authorization: Bearer $CANARY_API_KEY" | jq '.monitors[] | select(.name=="linejam-production-smoke")'

+# Static Release Store (`content/releases/`)
+
+`app/releases/page.tsx` reads `content/releases/manifest.json` + one
+`content/releases/vX.Y.Z/{changelog.json,notes.md}` per version via
+`lib/releases/loader.ts`. This is the **only** store the page reads.
+
+## The split-brain it replaces (linejam-915)
+
+Before this fix, `content/releases/` was written once (v0.1.0, January 2026)
+and never again — meanwhile Landmark's release workflow kept a second store,
+`docs/releases/feed.xml` (RSS), current through every release. The page
+showed v0.1.0 while the app itself was on v1.15.1. Two stores, one dead,
+nothing keeping them in sync.
+
+## The fix: one writer, one source
+
+`.github/workflows/release.yml` runs
+`scripts/release/write-release-from-git.mjs` immediately after Landmark tags
+a release (`if: steps.landmark.outputs.released == 'true'`), then commits
+`content/releases/` back to master. It:
+
+1. Derives the technical `changes` array **deterministically** from git
+   history between the previous tag and the new one
+   (`scripts/release/conventional-commits.mjs` — parses Conventional
+   Commits, drops `chore(release)`/`chore(feed)` automation noise, extracts
+   PR numbers and `BREAKING CHANGE`/`!` markers). No LLM in this path.
+2. Writes Landmark's already-synthesized `release-notes` output as
+   `notes.md` prose. This reuses the synthesis pipeline already producing
+   every GH Release body and RSS entry in this repo today — not a new trust
+   surface. (Landmark's synthesis fabrication risk, caught 2026-07-04 in a
+   sibling repo and tracked as `landmark-907`, only affects prose quality;
+   the technical `changes` array this page's collapsible detail relies on
+   never touches an LLM.)
+3. Regenerates `manifest.json` from the version directories actually
+   present on disk (`scripts/release/static-release-store.mjs`), so the
+   manifest can never itself drift from the content it indexes.
+
+## Backfill
+
+`scripts/release/backfill-static-releases.mjs` walked every `v1.*` git tag
+(21 versions, `v1.0.0`..`v1.15.1`) and wrote each one's deterministic
+`changelog.json` the same way. It does not fabricate `notes.md` prose for
+historical versions — `lib/releases/loader.ts` already tolerates a missing
+`notes.md` (empty `productNotes`, technical details still render). Re-running
+it is safe and idempotent; it only reads git history and regenerates output.
+
+## The gate
+
+`tests/scripts/release-manifest-version.test.ts` runs in the normal test
+suite (every PR, every push) and fails if `manifest.json`'s `latest` does
+not equal `package.json`'s `version`, if the latest version isn't listed
+first, or if any listed version is missing its `changelog.json`. This is
+what makes drift structurally impossible to reintroduce silently: the build
+goes red before a release ships, not eight months after.
+
+## Deleted: the old manual generator
+
+`scripts/generate-releases.ts` + `lib/releases/parser.ts` predated this fix
+(the `v0.1.0`-era "static file-based releases infrastructure"). It parsed
+`CHANGELOG.md` and called OpenRouter directly with a bare prompt and no
+grounding gate — exactly the fabrication risk `landmark-907` exists to fix,
+but with no fallback protection at all beyond a generic "this release brings
+N features" string. It was never wired into CI or `release.yml`, had no
+tests, and nothing else imported it. Keeping it around would have left a
+second, riskier writer to `content/releases/` that could reintroduce the
+exact split-brain this card fixes the moment anyone ran
+`pnpm generate:releases` by habit. Deleted rather than fixed in place; the
+one authoritative writer is `release.yml` via `scripts/release/`.

+(`tests/app/join-page.test.tsx`) before the ratchet, taking it to 97%/89%.
+Remaining known-weak modules (not touched by this ratchet, tracked here so
+they aren't lost): `convex/ai.ts` (66%), `convex/lib/ai/personas.ts` (62%),
+`convex/errors.ts` (67%), `components/RoomChrome.tsx` (75%/61% functions),
+`app/(auth)/callback/page.tsx` (84%) -- good candidates for the next ratchet
