 - **#6 — Migrations were bare scripts. RESOLVED** by `migration-tool` convoy (2026-05-26). `node-pg-migrate@^8` is the chosen tool (lightweight, raw-SQL-friendly, zero TS surface — matches the repo's JavaScript-only `@vercel/postgres` style). New migrations live under `migrations/` at the repo root and use the default `pgmigrations` tracking table. The initial backfill `migrations/1779853647564_initial-schema.js` reproduces `scripts/setup-neon-db.js`'s 7-table DDL verbatim using `CREATE TABLE IF NOT EXISTS`, so it's idempotent against fresh AND pre-existing envs — first-time `npm run migrate up` on an env that already ran `setup-neon-db.js` pre-convoy is a no-op DDL-wise (only records the `pgmigrations` row). The legacy 27 `scripts/add-*.js` / `scripts/fix-*.js` / `scripts/seed-*.js` jobs are append-only history per the no-go-zones rule — do NOT add new ones. New column / constraint work ships as a `node-pg-migrate` migration. See § 3 Conventions § "Schema changes" above + `.convoys/migration-tool.md`. Entry kept (not renumbered) to preserve cross-references.
 - **#7 — Dual `is_public` semantics.** Collections and decks both have `is_public` columns; check which controls discovery vs. anonymous read in the relevant route.
 - **#8 — Layout has hardcoded default user. RESOLVED** by `fix-layout-default-user` convoy (PR #15, squash commit `ca302a8`). `components/Layout.js`'s default prop is now `null`; `UserProfileDropdown` renders a `<Link href="/login">Sign in</Link>` CTA when `user === null`. Brief 2 also swept the 7 pages that needed page-level fixes (`scanner` / `decks` / `deck-builder` / `deck/[id]` now pass `user={user}` to Layout; `profile` / `settings` replaced leaky `useState({email:'me@…'})` with `useState(null)` + null-guards on every sync `user.*` read; `card/[id]` swapped a hardcoded `const user = {...}` for `useAuth()` from `lib/use-auth.js`). `test/components/Layout.test.js` adds 5 regression-lock assertions (no maintainer email when user is null/omitted; "Sign in" link present; supplied email renders; no "Guest" placeholder); vitest 21/21 green at merge.

   - **Vitest:** the `test:` job in `.github/workflows/ci.yml` runs `npm run test:run` on every PR and push to `main` and is **blocking** (no `|| true`, no `continue-on-error`). A red test job blocks merge.
   - **Playwright smoke:** runs on every PR via `preview-smoke.yml`. Gate skip via `pipeline: skip smoke` in the PR body (handled in the `gate:` job's Decide step via env-var routing — see § 7's shell-injection note). Last measured runtime: 59s end-to-end, 3/3 tests pass in 2.9s (PR #18 post-merge run).
   - **Screenshot diff:** runs only on PRs touching `pages/**` / `components/**` / `styles/**` / `tailwind.config.js` / `postcss.config.js` via `visual-diff.yml`. **First `Screenshot diff` run after `adopt-playwright-smoke` will fail at the test step** because no baseline exists yet; `continue-on-error: true` swallows the failure and the comment-on-PR step posts "Visual Diff — view run" with empty artifacts. That is the documented Decision-4 end state of `adopt-playwright-smoke`, not a regression — it stays that way until `seed-visual-baselines-on-linux` lands.
+- **CI minute optimizations (slash-ci-minutes convoy, 2026-06-04):**
+  - **Doc-only PRs skip ALL of ci.yml + preview-smoke.yml.** Both workflows carry `paths-ignore` for `.convoys/**`, `**/*.md`, `docs/**`, `AGENTS.md`, `.cursor/**`, and `README.md`. A pure-docs PR triggers zero GitHub Actions jobs (Vercel still builds — it's not on the Actions billing). `visual-diff.yml` was already cost-conscious via a positive `paths:` allowlist and is unchanged.
+  - **The 6 grep-only forbidden-* jobs collapsed into one.** They previously ran as 6 independent jobs (each with its own `actions/checkout`); the consolidated `forbidden-patterns` job runs all 6 checks as labeled `::group::` sections in a single bash step, with a FAIL flag at the bottom so every violation across all 6 checks still surfaces in one run (same diagnostic behavior, ~5/6 of the per-PR checkout overhead removed). The 6 original job names (`forbidden-endpoints`, `forbidden-cors-headers`, `forbidden-client-side-llm-keys`, `forbidden-modal-shell-without-primitive`, `forbidden-deprecated-color-aliases`, `forbidden-stale-strings`) no longer appear in the checks list — references in this file (e.g. CI job `forbidden-stale-strings` blocks ...) are now informational, not check-name lookups. `pr-health-rollup.yml` was unaffected because it only looks up `Lint` and `Schema map up to date` by name.
+  - **`node_modules` cached between runs** in lint / test / migrate / preview-smoke / visual-diff. Keyed on `package-lock.json` hash so any dep change invalidates correctly. Cuts `npm ci` from ~30-45s to ~3-5s on cache hit. `actions/setup-node@v4`'s built-in `cache: npm` is layered above this (caches `~/.npm`) — both stay because the `setup-node` cache helps on cache-miss days too.
+  - **Playwright browsers cached** in `preview-smoke.yml` + `visual-diff.yml`. Keyed on the resolved `@playwright/test` version from `package-lock.json`. Cache invalidates automatically on any Playwright version bump. On cache hit, only the system deps install (`npx playwright install-deps chromium`) runs — saves ~15-25s/run.
 - **Manual QA:** `TESTING_GUIDE.md` still applies for flows not yet covered by automated tests (scanner camera path, card-import jobs, multi-step UI wizards). The automated smoke + visual suite is steadily eclipsing it; `TESTING_GUIDE.md` will be renamed to `docs/MANUAL_QA.md` and trimmed to truly-manual-only flows in a future cleanup convoy (see `.convoys/ship-readiness.md` § Role-doc-writer findings).
