Summary

tests/release-version-line.test.ts (merged in #2739) compares package.json against the newest release tag. That only works because the two suite-running CI jobs now pass fetch-tags: true — and nothing asserted that setting.

An independent reviewer flagged the consequence: remove the flag and the guard goes quietly inert. git is still present, git tag --list still exits 0, stdout is just empty, so the check reads an empty tag set, cannot fail, and a version regression rides through green. That is precisely how the first cut of that test shipped, which is reason enough not to leave the flag protected by a comment.

The assertion is per job rather than a string count, so an edit cannot drop the flag from one leg while the other still carries it.

Verification

  • bun test ./tests/ci-workflows.test.ts — 132 pass, 0 fail, 1357 expect() calls.
  • Driven red once: removing fetch-tags: true from the Linux shards fails with Expected: "test:true" / Received: "test:undefined" and names the offending job.
  • Test-only change; no workflow or runtime behavior is modified.

Checklist

  • Targets dev
  • Regression test driven red once
  • No runtime or workflow behavior change
  • Uses the existing Bun.YAML.parse job-scoped assertion style already in this file

Summary by CodeRabbit

  • Documentation

    • Added an independent verification section to the WP3 failover-identity planning document.
    • Clarified when cross-origin credential leakage could occur and refined the recommended remediation sequence.
  • Tests

    • Strengthened CI workflow validation to ensure test, macOS, and Windows jobs fetch Git tags during checkout.
    • Helps prevent version-regression checks from passing when tag information is unavailable.

The version-line guard depends on a checkout setting that nothing asserted. A
reviewer pointed out the obvious consequence: delete `fetch-tags: true` and
tests/release-version-line.test.ts goes quietly inert again - git is present,
`git tag --list` exits 0, stdout is empty, so the check has an empty set and
cannot fail. That is exactly how its first cut shipped, which is reason enough
not to leave the flag protected by a comment.

Asserted per job rather than by counting the string, so an edit cannot drop the
flag from one leg while the other still carries it. Driven red once: removing it
from the Linux shards fails with test:undefined vs test:true and names the job.

📝 Walkthrough

Walkthrough

The planning document adds an independent audit of failover identity behavior. CI enables Git tag fetching on Windows and validates the setting across the test, macOS, and Windows jobs.

Changes

Failover identity audit

Layer / File(s) Summary
Document independent failover verification
devlog/_plan/260827_dev_hardening/020_wp3_failover_identity.md:70-105

Estimated code review effort: 1 (Trivial) | ~5 minutes

Merge Risk: 🟡 Moderate · up to b8ad9

The PR adds per-job CI checks intended to preserve Git tags for release-version validation, but the current head still has a matcher that may accept the wrong checkout action and conflicting instructions in the related plan. That could leave the regression guard ineffective or cause future changes to be implemented incorrectly, so merge should wait for resolution or explicit owner acceptance.

…d audit

A second read-only audit checked the wp3 claims against dev rather than trusting
the first pass, and one of them was overstated.

Confirmed: applyFailoverSnapshot never updates sentOAuthSnapshot, the forced
refresh targets the snapshot's account (still A after a rotation), and the
three-site replay-identity asymmetry is exactly as tabled.

Corrected: the 429-then-401 cross-origin send is not reachable on today's control
flow. Copilot Responses models take an early passthrough return with no generic
429 rotator, and in the HTTP recovery loop the 401 handler sits above the 429
rotator while the 429 branch does not continue recovery - so a 401 after rotation
leaves the loop as an upstream error instead of re-entering the refresh.

This reframes the phase rather than weakening it. The missing continue is an
ACCIDENTAL guard: adding it, which is a plausible future improvement to 429
recovery, would activate the defect. So the identity rebind has to land before
anyone makes 429 recovery continue.

Also records where the behavioral tests belong, since the existing coverage
asserts on source text and cannot catch a rotation site that forgets a step.

P2 Badge Include the Windows suite job in the tag assertion

When platform-windows is run through workflow_dispatch, .github/workflows/ci.yml also executes the root tests suite in four shards, including release-version-line.test.ts, but its checkout currently omits fetch-tags. Because this list checks only Linux and macOS, the new guard passes while the Windows version check receives an empty tag set and silently skips its regression assertion; include platform-windows here and configure its checkout with fetch-tags: true.

Useful? React with 👍 / 👎.

platform-windows runs the whole suite with --shard (line 645), so it reads
release tags exactly like the Linux shards and the macOS control. It was missed
in the first pass because only the two legs that had already gone red were
considered. The assertion now covers all three legs, so the omission cannot
recur silently.

**Corrected.** The 429-then-401 cross-origin send is NOT reachable on today's control
flow, so the table above overstated the consequence. Copilot Responses models take an
early passthrough return that has no generic 429 rotator at all, and in the HTTP
recovery loop the 401 handler sits ABOVE the 429 rotator while the 429 branch does not
`continue recovery` - so a 401 after rotation falls out of the loop and is returned as
an upstream error rather than re-entering the refresh. The runTurn and sidecar paths
never re-enter those 401 blocks either.

📐 Maintainability & Code Quality | 🟡 Minor | ⚡ Quick win

Reconcile the regression-test claim with this reachability correction.

Lines 81-87 state that the 429-then-401 path is not reachable today. However, Lines 65-66 still say that the Copilot A → 429 → B → 401 test “Fails today.” Update the earlier test item to identify it as a forced-path or future regression test, or replace it with a currently reachable case. Otherwise, the plan directs maintainers to test a production path that this audit says cannot execute.

🎯 Functional Correctness | 🟡 Minor | ⚡ Quick win

Match the canonical checkout action exactly.

Line 165 also matches action identifiers such as acme/actions/checkout-fork. If that step has fetch-tags: true, the test passes even though the real actions/checkout step is missing or unconfigured. Use step.uses.startsWith("actions/checkout@") to protect the release-tag prerequisite.

Proposed fix
-      const checkout = steps.find(step => typeof step.uses === "string" && step.uses.includes("actions/checkout"));
+      const checkout = steps.find(step => typeof step.uses === "string" && step.uses.startsWith("actions/checkout@"));

리뷰 · 우선순위 64 / 80

이 PR은 지금 dev(HEAD ca3b379e1, Merge #2739)에 방금 들어온 버전 줄 가드가 CI에서 조용히 꺼지지 않게, 체크아웃에 fetch-tags: true가 실제로 달려 있는지를 테스트로 못 박습니다. #2739가 tests/release-version-line.test.ts를 넣었고, 리눅스 test 잡(.github/workflows/ci.yml L280)과 macOS platform-macos 잡(L478)에는 이미 태그를 가져오게 했습니다. 그런데 윈도우 platform-windows 잡의 Checkout(지금 dev L605-611)에는 아직 그 플래그가 없습니다. 태그가 없으면 git은 있고 git tag --list는 성공하는데 출력만 비어서, 버전 가드가 실패할 수 없습니다. 그 구멍을 테스트가 잡겠다는 뜻은 맞습니다.

다만 제목과 본문은 "테스트만, 워크플로 동작은 안 바꿈"이라고 적혀 있습니다. 실제 파일은 세 개입니다. 테스트 파일, 윈도우 Checkout에 fetch-tags: true를 넣는 ci.yml, 그리고 WP3 자격 증명 페일오버 문서에 붙인 36줄 감사 정정입니다. 세 번째 파일은 CI 핀과 다른 일입니다. 자격 증명이 돌아가는 이야기라서, 테스트 PR에 같이 있으면 나중에 찾기 어렵습니다.

윈도우 잡은 지금도 github.event_name == 'workflow_dispatch'일 때만 돌아갑니다. 그래서 이 플래그가 지금 푸시/PR CI를 바꾸지는 않습니다. 그래도 윈도우가 다시 게이트에 들어올 때 같은 구멍에 빠지지 않게 미리 고정하는 선택은 타당합니다. 태그/배포는 이 시간에 하지 않습니다. package.json은 이미 2.34.0입니다.

라인 605-611 (.github/workflows/ci.yml) - 지금 dev 윈도우 Checkout에는 persist-credentials: false만 있습니다. 여기에 fetch-tags: true를 넣는 것은 리눅스·macOS와 맞추는 올바른 수리입니다.
라인 153 다음 (tests/ci-workflows.test.ts) - test / platform-macos / platform-windows 세 잡의 checkout with.fetch-tags가 true인지 잡 이름과 붙여서 검사합니다. 한 잡에서만 빠져도 실패해서, 주석만 믿는 구멍을 막습니다.
020_wp3_failover_identity.md - CI 핀 PR에 429/401 페일오버 신원 감사 정정이 들어갑니다. "오늘 경로에서는 429 다음 401이 다시 안 돈다"는 중요한 정정이지만, 본문의 Test-only 설명과 어긋납니다.

메인테이너의 판단이 필요한 지점

  • WP3 메모는 hardening 문서의 정정이라 가치는 있습니다. 이 PR에 같이 둘지, 문서만 따로 둘지 정하면 됩니다. 자격 증명 표면이라 CI 테스트와 이력을 섞지 않는 편이 낫습니다.
  • 윈도우 잡은 아직 평소 CI에서 안 돕니다. 리눅스·macOS만 잠그고 윈도우는 나중에 해도 되는지는 운영 선택입니다. 이 PR은 세 잡을 같이 잠급니다.

너의 추천
CI 핀과 테스트는 지금 dev 기준으로 머지해도 됩니다. WP3 문서 추가는 이 PR에서 빼고 hardening 문서로 따로 두는 것을 추천합니다. 같이 넣을 거면 제목과 본문을 고쳐서 두 가지를 같이 다룬다고 밝혀야 합니다. 태그/배포는 하지 마세요.
