Summary

#55#62 のマージ済み PR を「CI / CLAUDE.md に反映すべきものが残っていないか」という観点で棚卸しし、見つかった 2 件を直しました。ドキュメントのみで、コードは 1 行も変えていません。

PR CI/CLAUDE.md への反映 取りこぼし
#55 test の lint なし(test のみ)
#56 リリースゲート統一 両方更新済み check:pack が Commands 一覧に無い
#57 テーマ色 なし
#58 correct intent なし(ヘッダの遅れは #61 で追跡中)
#59 check-pack → TS なし typecheck が「2 つの tsconfig」のまま
#62 check-apps → TS CLAUDE.md 更新済み

1. yarn typecheck の範囲。 #59scripts/tsconfig.json が加わって 3 つを見るようになりましたが、CLAUDE.md は two tsconfigs、README は src and test のままでした。同じ主張が 2 面にあり、両方腐っていた形です。scripts/ にはリリースゲート 2 本が住んでいるので、ここが抜けていると「コンパイルが通らなくなったゲートは、リリース時に走らせて初めて見つかる」ことになります。

2. リリースゲートが一覧に無い。 #56 は 2 本のゲートを package.json に一本化した PR で、目的は「走らせ方が 1 つになる=見つけやすい」ことでした。ところが check:pack は CLAUDE.md の Commands ブロックにも README にも載っておらず、CI の説明の散文の中にしかありませんでした。目的の半分が届いていません。typecheck:summary(ゲートではなくレポート)も併せて載せています。

Items to Confirm / Review

  1. README に足した段落の位置("Working on it" の直下)。check:apps は CI に置けない(private な ../apps checkout が要る)ので、そこを 1 行で書いています。CLAUDE.md 側にはもともと詳しい説明があるので重複させていません。
  2. typecheck のコメントに「なぜ scripts/ が忘れられやすいか」まで書いたこと。 事実の列挙だけなら 1 行で済みますが、この repo の慣習(ヘッダは設計文書)に寄せて理由を残しました。冗長なら削ってください。
  3. typecheck:summary を「REPORT, not a gate」と明記したこと。 床(floor)は持っているので実質ゲートでもありますが、CI では always() で走りタイプエラーでも結果を出す位置づけなので、この書き方にしています。

裏取り

書いた記述が実態と合っているかを機械的に照合しました:

  • CLAUDE.md / README / ci.yml が語る yarn <script>package.json の scripts と突き合わせ → 実在しない script を語っている箇所は無しどこにも書かれていない script も無し
  • two tsconfigs / src and test の残存を全ドキュメントに grep → 残りなし

コード変更が無いので format:check のみ実行(通過)。

User Prompt

  • 55-62 の isamu の PR で、CI や CLAUDE.md に反映すべきものがあったら反映してほしい

Summary by Sourcery

Synchronize project documentation and CI comments with the actual typechecking scope, release gates, and type-coverage enforcement behavior.

Enhancements:

  • Align documentation with the three-project scope of yarn typecheck and document the available release scripts and typecheck report.
  • Clarify that typecheck summaries also enforce per-project coverage floors while continuing to run after typecheck failures.

Documentation:

  • Update CLAUDE.md and README command documentation to include scripts in typechecking and list package and apps release gates.

Summary by CodeRabbit

  • Documentation
    • Clarified that type-checking covers source code, tests, and scripts.
    • Documented type-coverage reporting and enforcement of per-project coverage thresholds.
    • Added guidance for package validation and application checks, including release and private-checkout workflows.
  • Chores
    • Clarified CI output to explain that insufficient type coverage fails the check and can catch type-safety regressions.

#55#62 のマージ済み PR を CI / CLAUDE.md 観点で棚卸しした結果、反映漏れが 2 件あった。

- `yarn typecheck` は #59 で scripts/ の tsconfig が加わって 3 つを見るようになったが、
  CLAUDE.md は「two tsconfigs」、README は「src and test」のまま。同じ主張が 2 面にあり、
  両方腐っていた。scripts/ にはリリースゲートが住んでいるので、ここが抜けていると
  「コンパイルが通らなくなったゲートはリリース時に走らせて初めて見つかる」ことになる。
- #56 が 2 本のリリースゲートを package.json に一本化したのに、`check:pack` は CLAUDE.md
  の Commands ブロックにも README にも載っていなかった。一本化の目的が見つけやすさなので、
  一覧に無いと目的の半分が届かない。`typecheck:summary` も同様に載せた。

書いた記述の裏取りとして、CLAUDE.md / README / ci.yml が語る yarn コマンドを package.json
と突き合わせた: 実在しない script を語っている箇所は無く、どこにも書かれていない script も
無い。「two tsconfigs」「src and test」の残りも無し。

Reviewer's guide (collapsed on small PRs)

Reviewer's Guide

Documentation now reflects that yarn typecheck covers src, test, and scripts, and makes the release-gate commands discoverable while distinguishing the typecheck summary report from actual gates. The changes are limited to CLAUDE.md and README.md; reviewers should verify the descriptions and command placement against package scripts and CI behavior.

File-Level Changes

Change Details Files
Align documentation with the three-project scope of yarn typecheck.
  • Update CLAUDE.md to describe checking src, test, and scripts with separate tsconfigs.
  • Update README.md to replace the outdated src/test-only description.
  • Document why scripts/ matters because it contains release gates.
CLAUDE.md
README.md
Make release-gate commands discoverable in the primary command documentation.
  • Add check:pack to the CLAUDE.md Commands list.
  • Add typecheck:summary and clarify that it is a report rather than a gate.
  • Add README guidance for running check:pack in CI and check:apps manually before releases.

Review Change Stack

📝 Walkthrough

Walkthrough

The documentation now describes typecheck coverage enforcement, validation across src, test, and scripts, release-gate commands, and the CI coverage gate behavior.

Changes

Release and Typecheck Documentation

Layer / File(s) Summary
Validation command documentation
CLAUDE.md, README.md
The documentation describes the expanded typecheck scope, per-project coverage enforcement, check:pack, and check:apps.
CI coverage gate documentation
.github/workflows/ci.yml
The CI comment identifies the typecheck coverage step as both a report and a gate that fails below the coverage floor.

Estimated code review effort: 1 (Trivial) | ~2 minutes

Merge Risk: 🔵 Low · up to 2fab6

The documentation currently describes coverage enforcement as using a universal threshold, although each project has its own configured floor. This is a localized, non-blocking wording issue that should receive owner follow-up before or alongside merge.

The two release gates are `yarn` scripts too, so there is one way to run them and it is the
way CI runs them — `yarn check:pack <tarball>` (in CI) and `yarn check:apps [path]` (by hand,
before a release: it needs the private apps checkout CI cannot have).

Add yarn typecheck:summary to the README command list.

README.md lists yarn typecheck and the two release gates, but it omits the typecheck report command documented in CLAUDE.md. Add yarn typecheck:summary and mark it as a report, not a gate, so the README matches the PR objective.

CODEX VERDICT: LGTM

  • No findings. I rechecked every changed claim against package scripts, the three tsconfigs, scripts/*.ts, and .github/workflows/ci.yml.
  • Verification exit codes: yarn install --frozen-lockfile 0, yarn test 0, yarn typecheck 0, yarn lint 0, yarn format:check 0, yarn build 0, yarn typecheck:summary 0, yarn pack --filename package.tgz && yarn check:pack package.tgz 0. I did not run yarn check:apps, per the missing ../apps checkout note.
  • The command sweep found no documented yarn <script> that is absent from package.json, and no relevant package script left without a documentation/lifecycle mention across CLAUDE.md, README.md, and ci.yml.
Axis Findings
1. correctness none — the new prose matches package.json, the three tsconfigs, scripts/*.ts, and CI. typecheck:summary is correctly described as both report and gate because floor failures set a non-zero exit code.
2. security none — the workflow change is comments only; permissions remain contents: read, with no secrets or permission expansion.
3. tests none — this is prose/comment drift. Existing executable checks cover the underlying behavior; there is no useful additional test for the wording itself.
4. API / schema / wire / on-disk compatibility none — docs/comments only; no runtime, schema, package export, or persisted-data shape changes.
5. consistency with the rest of the codebase none — CLAUDE.md and README.md now agree with each other and with the scripts/CI on typecheck, check:pack, check:apps, and typecheck:summary.
6. accessibility and i18n lockstep n/a — the PR changes repository docs and workflow comments only; no user-facing UI text, locale resources, or accessibility surface is touched.

FINDINGS COMPLETE: I read every hunk of the diff and this is every finding I have.

Codex exchange — iteration 1 (tier S, promoted from T) — FINAL

Prompt sent (verbatim)
Review PR #65 at https://github.com/receptron/sharedapp/pull/65
(repo at /Users/isamu/ss/llm/sharedapp; branch docs/command-drift; base origin/main).
Read CLAUDE.md in the repo root FIRST.

TIER: started at T (two markdown files), **PROMOTED TO S** during my own pass 1, because that pass
produced a P2 — so the tiering was wrong and this gets a Codex round. Nothing demotes.

── THIS IS THE ONLY ROUND YOU ARE GUARANTEED ────────────────────────────────
Read the WHOLE diff before you post anything. Do not hold anything back.

── WHAT THE PR DOES ─────────────────────────────────────────────────────────
Documentation only, no code. It came out of an audit of merged PRs #55-#62 asking "is there
anything that should have landed in CI or CLAUDE.md and did not". Two things had not:

1. `yarn typecheck` runs THREE tsconfigs since `scripts/tsconfig.json` was added, but CLAUDE.md
   said "two tsconfigs" and README said "src and test". The same claim was stale on BOTH surfaces.
   `scripts/` is where the release gates live, so the gap meant a gate that stopped compiling would
   be found by running it at release time.
2. PR #56 unified the two release gates into `package.json` scripts precisely so there would be one
   way to run them — but `yarn check:pack` appeared in neither command list, only in prose.

── WHAT MY OWN PASS 1 THEN FOUND, AND WHY THE TIER WENT UP ──────────────────
The PR's first version described `yarn typecheck:summary` as "a REPORT, not a gate". That is FALSE:
`scripts/typecheck-summary.ts` sets `process.exitCode = 1` when a per-project type-coverage floor is
breached, and it has already failed a real CI run (PR #67, where `Array.isArray` narrowing `unknown`
to `any[]` put four `any`s into a project whose floor is 100).

The same false claim was ALREADY in `.github/workflows/ci.yml:30` — "A report, not a gate" — so the
fix touches that file too. That is why a docs PR now edits a workflow.

── AXES — answer EVERY line, even when the answer is 'no findings' ──────────
  1. correctness — is every statement in the new text TRUE of the code as it stands? Check each one
     against `package.json`, the three tsconfigs, `scripts/*.ts` and `.github/workflows/ci.yml`.
  2. security (secrets, permissions — the workflow is edited here, though only its comments)
  3. tests: is there anything here a test could pin, or is it correctly untestable prose?
  4. API / schema / wire / on-disk compatibility
  5. consistency with the rest of the codebase — CLAUDE.md and README describe overlapping things;
     do they now agree with each other as well as with the code?
  6. accessibility and i18n lockstep (say 'n/a' with the reason if there is none)

An axis with no findings is a RESULT and has to be stated.

── THE SPECIFIC THING I WANT CHECKED ────────────────────────────────────────
This PR is ABOUT documented claims that had gone stale, so a claim it introduces that is false is
the worst possible finding. I swept `yarn <script>` mentions across CLAUDE.md, README.md and
`ci.yml` against `package.json` and found no script documented that does not exist and no script
that is documented nowhere. Redo that sweep rather than trusting it, and check the PROSE too — the
sentences about what each command covers, not just the command names.

── EACH FINDING CARRIES FOUR THINGS ─────────────────────────────────────────
1. SEVERITY — P1 / P2 / P3.  2. EVERY SITE (grep, list them all now).
3. THE SMALLEST CHANGE THAT RESOLVES IT.  4. WHAT WOULD CHANGE YOUR MIND.

── HOW TO RUN THINGS ────────────────────────────────────────────────────────
  yarn test   yarn typecheck   yarn lint   yarn format:check   yarn build   yarn typecheck:summary
  `yarn check:apps` FAILS here by design: the sibling `../apps` checkout is absent.
CHECK EXIT CODES, not the presence of an expected line.
`rm -f` is blocked in your sandbox: do NOT run a mutation sweep.

── ALREADY SETTLED — do not raise these again in the same form ──────────────
| # | iter | finding | disposition | why |
|---|------|---------|-------------|-----|
| 0 | pre | sandbox pre-flight 02:59Z today, same machine/CLI/flags: test 0, typecheck 0, socket 0, api.github.com 200, `gh pr view` works, `rm -f` BLOCKED | N/A | reused |
| 1 | pass 1 | "a REPORT, not a gate" was false on two surfaces (CLAUDE.md and ci.yml) | FIXED | commit 2fab6e8; `process.exitCode = 1` on a floor breach, and it has failed a real CI run |

── END WITH ONE TOP-LEVEL COMMENT, IN THIS ORDER ────────────────────────────
  Line 1: 'CODEX VERDICT: LGTM' or 'CODEX VERDICT: CHANGES REQUESTED' + a bulleted summary.
  Then the axis table: one row per axis 1-6, findings or 'none'.
  Then, on its own line:
    'FINDINGS COMPLETE: I read every hunk of the diff and this is every finding I have.'

Do not apply any fixes yourself — only review and post findings.

Codex reply (verbatim stdout):

Posted the top-level PR comment: https://github.com/receptron/sharedapp/pull/65#issuecomment-5434962228

Verdict was `CODEX VERDICT: LGTM`. No findings across the requested axes. Verification commands all exited 0 except `yarn check:apps`, which I did not run per the missing `../apps` checkout constraint.

Its posted verdict is #issuecomment-5434962228 — CODEX VERDICT: LGTM, six axes none,
FINDINGS COMPLETE present, every gate verified by exit code.

No step C-bis: nothing was declined, so there was no rebuttal to settle.

Triage — iteration 1 — CLEAN, loop ends

Tier: started T, PROMOTED TO S. The tier is a prediction about where the bugs are, and mine
failed: my own pass 1 produced a P2, so "two markdown files, nothing to review" was wrong and this
owed a Codex round. Nothing demotes.

Codex: CODEX VERDICT: LGTM — six axes none, FINDINGS COMPLETE present, every gate
verified by exit code (install --frozen-lockfile, test, typecheck, lint, format:check,
build, typecheck:summary, pack + check:pack, all zero). Nothing pushed since it read the
head, which is 2fab6e8.

# finding severity raised by disposition
1 typecheck:summary described as "a REPORT, not a gate" — on two surfaces P2 me, pass 1 FIXED before round 1

What the promotion was for

The PR's first version added this line to CLAUDE.md:

yarn typecheck:summary # a REPORT, not a gate

scripts/typecheck-summary.ts sets process.exitCode = 1 when a per-project type-coverage floor
is breached, and it has already failed a real CI run — PR #67, where Array.isArray narrowing
unknown to any[] put four anys into a project whose floor is 100.

The same false claim was already sitting in .github/workflows/ci.yml:30 — "A report, not a gate"
— which is why a docs PR ends up editing a workflow. Both surfaces now say it is both, and the
CI comment names the regression it caught, so the sentence has something to be checked against.

That is the failure mode worth naming: a comment telling people a red job is ignorable. It costs
nothing until the job goes red for a reason that matters.

Codex confirmed the correction independently — "correctly described as both report and gate because
floor failures set a non-zero exit code" — and re-ran the sweep I had run: no documented
yarn <script> missing from package.json, and no package script left undocumented across
CLAUDE.md, README.md and ci.yml.

One round, and why

The finding arrived in my own pass, before Codex saw the head — so the fix and the review landed
together instead of costing a round each. That is the whole of what tiering buys when it works;
here it also cost the tier, which is the trade being made honestly rather than quietly.
