# Phase 13 Plan 03: Prettier Reformat + CI Format Gate Summary

Prettier reformat applied as one isolated mechanical commit across the entire repo (D-13-08), CI fast-checks job gains a `Format check` step, and the baseline gate ends green: `pnpm lint` AND `pnpm format:check` both exit 0.

## Outcome

SC-3 met. The lint and format gates are real, wired into CI, and green.

- `pnpm lint` — exit 0 (both apps, `--max-warnings 0`)
- `pnpm format:check` — exit 0 (all matched files use Prettier code style)
- `pnpm typecheck` — exit 0 (both apps + e2e tsconfig)
- `pnpm --filter @familysync/pwa test` — 191/191 passing
- `pnpm --filter @familysync/api test` — 237/238 passing with dev DB (one pre-existing intermittent timeout, unchanged from Plan 02)

## Tasks Completed

| Task | Description | Commit |
|------|-------------|--------|
| 1 | Prettier reformat — single isolated mechanical commit | 982438d |
| 2 | Add Format check CI step; remove stale no-op lint comment | 0422406 |
| 3 | Green-baseline assertion (SC-3) | (verification only) |

## Reformat Diff Stat (Task 1 Evidence)

```
398 files changed, 19125 insertions(+), 16457 deletions(-)
```

Files reformatted span: `apps/api/src/**`, `apps/api/tests/**`, `apps/pwa/src/**`, `apps/pwa/e2e/**`, root config files (`eslint.config.js`, `pnpm-workspace.yaml`, `CLAUDE.md`, `README.md`, `docs/**`), `.planning/**`, `.claude/**`. Prettier 3.8.4 with `.prettierrc` settings (singleQuote:true, semi:true, tabWidth:2, trailingComma:all, printWidth:100). No logic changes — purely whitespace, wrapping, trailing-comma normalization.

## CI Step Ordering After Task 2

Final `fast-checks` job step order:
1. `actions/checkout@v4`
2. `actions/setup-node@v4` (Node 22)
3. Enable pnpm
4. Install dependencies (`pnpm install --frozen-lockfile`)
5. **Lint** (`pnpm lint`)
6. **Format check** (`pnpm format:check`) — NEW
7. Typecheck (`pnpm typecheck`)
8. PWA unit tests (`pnpm --filter @familysync/pwa test`)

Stale 3-line comment ("lint is currently a no-op…") removed. Branch-protection contexts (`name: CI`, `fast-checks`, `api`, `harness` job ids) unchanged.

## Green Baseline Exit Codes (SC-3)

| Command | Exit Code |
|---------|-----------|
| `pnpm lint` | 0 |
| `pnpm format:check` | 0 |
| `pnpm typecheck` | 0 |
| `pnpm --filter @familysync/pwa test` (191 tests) | 0 |
| `pnpm --filter @familysync/api test` (dev DB) | 1* |

*API integration tests: 237/238 pass with the dev MariaDB running. One test ("toggling isShared false→true re-populates list_shares") times out at 5000ms — this is the same pre-existing intermittent timeout documented in the 13-02 SUMMARY. The Prettier reformat is purely mechanical (confirmed by diff inspection: only whitespace/indentation changed, the `await import('drizzle-orm')` call sequence is identical). Not a regression.

## SC-2 Note for Operator

The CI lint and format:check steps now genuinely block PRs to main. SC-2's "CI actually blocks a PR" confirmation is a one-time observation on the next real PR to main — this cannot be auto-confirmed locally. Flagged for the operator: the next PR to main against `gsd/phase-13-real-lint-gate-eslint` (or any branch with a lint/format violation) will verify the blocking behavior.

## Deviations from Plan

None — plan executed exactly as written.

Task 1 ran `pnpm format` which also reformatted `.planning/**` and `.claude/**` files (not excluded by `.prettierignore`). These were included in the isolated mechanical commit per D-13-08 intent (one full-repo reformat commit). The plan listed `apps/api/src/**`, `apps/pwa/src/**` etc. as the primary targets; the additional files are consistent with "Prettier owns".

## Known Stubs

None.

## Threat Flags

None. No new network endpoints, auth paths, file access patterns, or schema changes. The ci.yml edit only adds a new step in an existing job — branch-protection contexts are preserved.

## Self-Check: PASSED

Files verified:
- `.gitea/workflows/ci.yml` — contains "Format check" step + "pnpm format:check" + "fast-checks:" — FOUND
- `.planning/phases/13-real-lint-gate-eslint/13-03-SUMMARY.md` — FOUND (this file)

Commits verified:
- `982438d` — FOUND (style(13-03): apply Prettier formatting across repo)
- `0422406` — FOUND (feat(13-03): add Format check CI step; remove stale no-op lint comment)

Green baseline verified:
- `pnpm lint` — exit 0
- `pnpm format:check` — exit 0
- `pnpm typecheck` — exit 0
- `pnpm --filter @familysync/pwa test` — 191/191 passing
