<objective>
Close the phase: (1) run Prettier across the whole repo as a single isolated reformat commit (D-13-08), (2) add the `Format check` CI step to the fast-checks job and remove the now-false no-op lint comment (SC-2), (3) assert the green baseline — `pnpm lint` AND `pnpm format:check` both exit 0 across both apps (SC-3). This is the last wave; after it, the lint+format gate is real, green, and wired into CI.

Purpose: SC-3 requires the first real run's baseline to end green; SC-2 requires the CI gate to actually block PRs to main. The reformat is isolated from logic fixes (Plan 02) so the large mechanical diff is reviewable on its own.
Output: reformatted tree (isolated commit), updated ci.yml, green lint + format baseline.

<artifacts_this_phase_produces>
No NEW files. MODIFIES:

- The whole source tree (Prettier reformat — isolated commit).
- `.gitea/workflows/ci.yml` — adds the `Format check` step; removes the stale 3-line no-op lint comment (ci.yml lines 28-30).

This completes the phase's full artifact set across all three plans:

- New config files (Plan 01): eslint.config.js, .prettierrc, .prettierignore
- New scripts (Plan 01): root format/format:check + type:module; apps/api & apps/pwa lint
- New CI step (Plan 03): Format check
- State: lint-clean (Plan 02) + format-clean (Plan 03) baseline, green in CI.

    - 13-RESEARCH.md "Prettier Configuration" (the .prettierrc settings + .prettierignore exclusions, so you know what gets formatted and what is skipped).

  </read_first>
  <action>
    Run `pnpm format` (`prettier --write .`) at the repo root. This reformats every file Prettier owns, respecting `.prettierignore` (dist/, node_modules/, pnpm-lock.yaml, apps/api/src/db/migrations/, *.html are skipped). Because `.prettierrc` sets `singleQuote: true` to match the existing codebase, the diff should be whitespace/wrapping/trailing-comma churn, not a mass quote flip.

    This reformat MUST be its own commit, isolated from Plan 02's lint fixes (D-13-08) — do not mix any logic change into it. After formatting, run `pnpm lint` to confirm the reformat did NOT introduce any lint violation (eslint-config-prettier means ESLint does not fight Prettier, so this should stay green from Plan 02). If `pnpm lint` is non-zero after reformat, a formatting/lint conflict exists — investigate the eslint-config-prettier placement (must be last) before proceeding; do not blanket-disable.

    Record `git diff --stat` (file count + line churn) in the SUMMARY as evidence of the mechanical reformat.

  <read_first>
    - .gitea/workflows/ci.yml — the fast-checks job, the existing `Lint` (lines 31-32) and `Typecheck` (lines 34-35) steps, and the stale no-op comment at lines 28-30.
    - 13-PATTERNS.md ".gitea/workflows/ci.yml — adding a Format check step" (exact step shape + the comment to remove) + the "CI step insertion" shared pattern (`- name: Verb noun` / `  run: pnpm <script>`).

  </read_first>
  <action>
    Edit ONLY the fast-checks job in `.gitea/workflows/ci.yml`:
      1. Remove the now-false 3-line comment above the Lint step (the "lint is currently a no-op … out of this phase's scope" block at lines 28-30) — it is no longer true now that real package lint scripts exist.
      2. Insert a new step between `Lint` and `Typecheck`, matching the existing step idiom exactly:
         `- name: Format check` / `  run: pnpm format:check`.
      Final fast-checks step order: Install dependencies → Lint → Format check → Typecheck → PWA unit tests.
    Do NOT touch the `api` or `harness` jobs, the `name: CI` line, or the `fast-checks` job id — those job ids are the required branch-protection contexts (STATE / memory: gitea main is protected, contexts must stay valid). No other CI change. No cache (D-PROBE-04 — the comment already documents why; leave it).

    Validate the YAML parses after the edit.

    Final phase gate (SC-3). Run, from the repo root, the full validation suite and confirm every command exits 0: `pnpm lint`, `pnpm format:check`, `pnpm typecheck`, `pnpm --filter @familysync/api test`, `pnpm --filter @familysync/pwa test`. This is the baseline-green proof: the lint AND format gates both pass across both apps, and nothing regressed. If any command is non-zero, fix forward within this plan (a residual format/lint/type issue) — the phase is not done until all are green (D-13-05).

- `pnpm format:check` exit 0 (whole tree Prettier-clean after the isolated reformat commit).
- `pnpm lint` exit 0 (reformat introduced no eslint/prettier conflict).
- ci.yml: `Format check` step present after Lint, stale no-op comment removed, YAML valid, `fast-checks` job id + `name: CI` unchanged.
- Full suite (lint + format:check + typecheck + api test + pwa test) all exit 0 — SC-3 baseline green.

<success_criteria>

- D-13-08: reformat is one isolated mechanical commit, separate from logic fixes.
- SC-2: CI fast-checks job has a real lint step (blocks on violations) + a new format:check step; stale comment removed; branch-protection contexts intact.
- SC-3: `pnpm lint` AND `pnpm format:check` both exit 0 across both apps; baseline gate ends green.
  </success_criteria>

<output>
Create `.planning/phases/13-real-lint-gate-eslint/13-03-SUMMARY.md` when done. Record: `git diff --stat` of the reformat (files + line churn), the exact ci.yml step ordering after the edit, and the final green exit codes for lint / format:check / typecheck / tests (SC-3 evidence). Note that SC-2's "CI actually blocks the PR" confirmation is a one-time observation on the next real PR to main (per 13-VALIDATION.md Manual-Only table) — flag it for the operator.
