Summary

Every release forces dev to catch up, and while it trails the highest tag,
tests/release-version-line.test.ts fails on dev and on every open pull request
— an inherited red a contributor cannot fix from their own diff.
.github/workflows/dev-version-bump.yml records four hand repairs in its own header
(32529c2b2, e4a85d134, 076ad3036, befcac3e1), and history shows
"move dev to 2.4x.0" once per release.

This lands the four-phase fix from an audited design unit. The design passed six
adversarial review rounds and twice retracted a claim rather than repairing it — the
retractions are the most important part of it.

What could NOT be done, and is now stated plainly. The per-release dev commit
cannot be deleted. It follows from Protect dev requiring review, release.ts
running only on main/preview, and a monotonically advancing tag set. An earlier
draft claimed otherwise; a reviewer proved ee2d19ad4's single parent is the
v2.42.0 release commit, making the catch-up PR the ancestry carrier, not merely
a version fix. A second draft then tried to preserve that ancestry — also impossible,
since release.ts:559-591 creates the release commit after promotion, so it is a
descendant. Both claims were withdrawn. Ancestry is explicitly not a property this
design maintains.

So the commit MOVES instead of disappearing. The version PR opens and merges
before the release rather than after it. Same number of reviewed commits, no red
window.

The four phases

Phase Change
010 scripts/version-line.ts — one shared, importable version algebra
020 --bump patch|minor|major with channel-specific resolvers
030 dev-version-bump.yml becomes a pre-release opener; two gates in release.yml
040 MAINTAINERS.md + SoT corrected; invariant retained

010 exists because the repository ordered releases in two places and only one was
reachable from a test. The two comparators stay deliberately different and a test now
pins that: compareVersions throws so a release decision fails closed, while
compareTagsLenient keeps the natural-ordering fallback. Collapsing them would be a
live regression — build-release-changelog.ts admits any /^v\d/ tag, so one
malformed historical tag would newly abort release-note generation.

020 keeps the channels apart. A single global floor would let a future
v2.43.0-preview.1 turn --bump minor into 2.44.0 and skip the intended 2.43.0.
A stable patch bump is now refused when a preview tag sits above the base.

030 deletes workflow_call together with its only caller, normalizes one target
version before the decision step, and adds a readiness gate plus an ordering gate. The
ordering gate runs after the fresh tag fetch — before it, the stale tag set would
defeat the point — and --allow-existing-tag-at-head is granted only for a dry run
whose tag names the exact SHA, preserving the deliberate exception already there.

040 is documentation only. tests/release-version-line.test.ts gains two comment
lines and nothing else; its assertions are byte-identical and tagPointsAtHead is
retained.

One policy consequence, stated deliberately

Publishing a preview for a higher core ends the current stable patch line. This is
a restriction, not the preservation of an unused capability: history contains real
counterexamples (v2.6.24-preview.20260705 then v2.6.23; v2.7.39-preview.20260724
then v2.7.37), and 103 of 143 stable tags carry patch > 0. It is recorded in
MAINTAINERS.md and the SoT so nobody re-derives it as a bug.

Verification

Phase-local checks were run by the implementing agents before the local-execution
freeze:

010: version-line 7 pass, bump-dev-version 10 pass (file unchanged), release-notes 71,
     release-version-line 3, release-helper 33, typecheck exit 0
020: version-line 20 pass, release-helper 39 pass, release-version-line 3 pass,
     typecheck exit 0, privacy:scan passed, docs-site build 425 pages
030: ci-workflows 136 pass, bump-dev-version 14 pass, version-line 20 pass,
     typecheck exit 0
040: documentation only; verified by diff inspection

New assertions were proven red before the change and green after: 020's resolver
suite failed on the higher-core patch refusal and the equal-stamp succession; 030's
ordering assertion fails when the gate is moved ahead of the tag fetch and passes when
restored; 010's lenient/strict distinction failed against a collapsed comparator.

Service lifecycle is already green on b181dd791, which exercises the changed
workflows. This PR exists so the full cross-platform matrix verifies the change set
on CI rather than on a developer machine.

tests/bump-dev-version.test.ts stayed green without edits through phase 010 —
that was the proof the algebra extraction was faithful.

Checklist

  • Scope stays focused and avoids unrelated cleanup.
  • Docs or release notes were updated when needed.
  • Security-sensitive changes were reviewed for secrets, auth, and unsafe defaults.

Security note: this touches release automation and workflow permissions, so it needs
maintainer security review per MAINTAINERS.md. No secret is added or logged; the
deleted workflow_call removes a contents: write caller path, and both new gates are
read-only assertions. privacy:scan passed during phase 020.

📝 Walkthrough

Walkthrough

The release process now uses shared version-line logic, supports explicit and derived release versions, moves dev before releases, and validates development readiness and global tag ordering. Workflow inputs, tests, maintainer guidance, architecture documentation, and localized contributing documentation are updated.

Changes

Release version-line controls

Layer / File(s) Summary
Shared version algebra and release bump resolution
scripts/version-line.ts, scripts/release.ts, scripts/release-notes.ts, scripts/bump-dev-version.ts, tests/ci-workflows/version-line.test.ts, tests/ci-workflows/release-helper.test.ts
Version parsing, strict and lenient comparison, development-version calculation, stable and preview resolution, --bump handling, release-floor checks, and CLI assertions are centralized and tested.

.github/workflows/dev-version-bump.yml, .github/workflows/release.yml, tests/ci-workflows/ci-workflows.test.ts, tests/ci-workflows/bump-dev-version.test.ts
The bump workflow uses manual dispatch with pre-move and repair modes. Release publication requires dev to outrank the target and the target to outrank fetched tags.
Release policy and implementation planning
MAINTAINERS.md, structure/06_docs-and-release.md, devlog/_plan/260904_release_version_line/*, docs-site/src/content/docs/*/contributing.md
Planning records, release policy, architecture guidance, migration notes, rollback notes, and localized contributor guides describe the pre-move flow and closed patch-line rule.

이 PR은 릴리즈마다 생기던 “dev가 새 태그보다 뒤처져서 tests/release-version-line.test.tsdev와 그 위 모든 PR에서 같이 빨갛게 되는” 문제를 고칩니다. 지금까지는 릴리즈가 끝난 뒤에 dev 버전을 따라잡는 PR을 열었습니다. 워크플로 헤더에만 네 번 손으로 고친 기록이 있고(32529c2b2, e4a85d134, 076ad3036, befcac3e1), 최근에도 #3045/#3076/#3127/#3354/#3434처럼 “move dev to …” 잡일이 반복됐습니다. 기여자 입장에서는 자기 diff와 무관한 빨강이라 고칠 수도 없습니다.

지금 dev HEAD는 00834d710(#3474, package 2.43.0)입니다. 제품 쪽은 Claude combo caps·reset-credit 쪽이고, 이 PR은 그 스택과 겹치지 않는 릴리즈 레일 작업입니다. 설계 결론도 분명합니다. Protect dev 때문에 봇이 dev에 직접 푸시할 수 없고, release.tsmain/preview에서만 돌아가며, 태그는 앞으로만 갑니다. 그래서 “따라잡기 커밋을 없앤다”는 첫 초안은 틀렸고, 커밋을 없애는 대신 시점만 앞으로 옮깁니다. 버전 PR을 릴리즈 전에 열고 머지하면, 새 태그가 찍히는 순간 dev는 이미 그보다 앞섭니다. 같은 개수의 리뷰 커밋으로 빨간 창이 사라집니다. 조상(ancestry)을 유지하겠다는 두 번째 초안도 철회됐습니다. 릴리즈 커밋은 프로모션 에 생기므로 조상이 될 수 없습니다.

네 단계가 한 PR에 실려 있습니다. 010은 scripts/version-line.ts로 버전 비교·다음 개발 버전·--bump용 resolver·게이트 CLI를 한곳에 모읍니다. compareVersions는 못 읽는 입력이면 던지고, compareTagsLenient는 예전 release-notes.ts처럼 관대합니다. 둘을 합치면 예전 깨진 태그 하나가 릴리즈 노트까지 멈출 수 있어서, 차이를 테스트로 고정했습니다. 020은 bun scripts/release.ts --bump patch|minor|major입니다. stable과 preview 채널을 따로 계산해서, 나중에 v2.43.0-preview.1이 있어도 stable minor가 2.44.0으로 건너뛰지 않게 합니다. 더 높은 코어의 preview가 열려 있으면 stable patch bump는 거절합니다. 030은 dev-version-bump.yml을 post-publish workflow_call에서 pre-move workflow_dispatch로 바꿉니다. release.yml의 호출 자리와 contents: write 전달 경로는 사라지고, 대신 readiness 게이트(origin/dev의 package.json이 릴리즈 버전보다 앞설 것)와 ordering 게이트(태그 집합을 새로 fetch한 뒤 assert-releasable)가 들어갑니다. 040은 MAINTAINERS.md·SoT·다국어 contributing 문구를 “닫을 때 고친다”에서 “열 때 먼저 옮긴다”로 고칩니다. 같은 제목의 #3479는 곧바로 닫혔고, 이 PR이 정식본입니다.

현재 태그 226개는 새 파서로도 전부 읽힙니다. CI도 hygiene·gates·linux/mac 서비스·test shard 쪽이 이미 초록이고, 이 글을 쓰는 시점엔 macos 매트릭스와 CodeRabbit만 아직 도는 중입니다. 로컬에서 적어 둔 단계별 검증(version-line / bump-dev-version / release-helper / ci-workflows / typecheck)과도 맞습니다. 다만 이건 릴리즈 자동화·권한 표면을 건드리는 변경이라 MAINTAINERS.md 기준 보안 리뷰가 필요합니다. 시크릿을 새로 넣지는 않았고, 오히려 호출 경로의 write 권한은 줄였습니다.

.github/workflows/dev-version-bump.yml - pre-move의 npm 존재 검사가 패키지 이름을 @bitkyc08/opencodex로 하드코딩한다. 같은 워크플로의 다른 자리와 release.ymlpackage.jsonname을 읽는데, 여기만 문자열이 고정이라 패키지 이름이 바뀌면 “이미 npm에 있다” 검사가 죽은 채 통과한다. 태그 검사가 더 세지만, 이름 소스는 하나로 맞추는 편이 안전하다.

scripts/version-line.ts assertReleasable - 태그 목록 전체에 엄격한 compareVersions를 쓴다. 지금 저장소에는 깨진 태그가 0개라 괜찮지만, 나중에 /^v\d/만 맞는 기형 태그가 하나 생기면 changelog(관대)는 살아 있고 publish 게이트만 갑자기 멈춘다. 의도된 fail-closed라면 주석/문서에 “깨진 태그는 릴리즈를 막는다”고 한 줄 더 박아 두는 게 좋다.

devlog/_plan/260904_release_version_line/050_migration.md - 첫 실전 순서가 pre-move(dev→2.44.0)promotemain에서 2.43.0 릴리즈(트리 버전을 낮춤) 이다. npm version이 높은 트리에서 낮은 버전으로 내려가는 건 확인됐고, 기존 게이트도 통과한다고 적혀 있다. 그래도 한 번이라도 순서를 뒤집으면 readiness가 막거나, 반대로 게이트 없이 옛 post-publish 경로가 남을 수 있다.

메인테이너의 판단이 필요한 지점

  • “더 높은 코어 preview를 내면 그 아래 stable patch 라인은 끝”이라는 정책 제한을 운영 규칙으로 받아들일지. 예전에 v2.6.24-previewv2.6.23 같은 역행이 실제로 있었다.
  • 이 스택을 dev에만 두고 바로 쓰지 말고, 다음 실릴리즈 전에 main/preview까지 같이 올릴지. readiness/ordering 게이트와 version-line.ts는 릴리즈 브랜치 체크아웃에서 실행된다.
  • pre-move를 사람 손 workflow_dispatch로 두는 현재 형태를 유지할지, 나중에 release helper가 디스패치까지 이을지.

너의 추천
CI(특히 macos·남은 매트릭스)가 초록이면 머지하고, 다음 실릴리즈(2.43.0) 전에 050_migration.md 순서대로 pre-move → promote → release를 한 번 연습처럼 따라가라. npm 패키지 이름 하드코딩은 머지 전후 작은 follow-up으로 package.json에서 읽게 바꾸면 충분하다. 같은 제목으로 닫힌 #3479는 추가 작업 없이 두면 된다.

Requesting changes on exact head b7be5a5aa736b2eb6ad000a23a8a4e050c1be82c. I verified two release-path blockers in the current code:

  1. scripts/release.ts resolves --bump from git tag --list v* before any remote tag fetch. If the maintainer clone is missing a newer tag while npm's channel is behind or inconsistent, the helper can select, commit, and push an obsolete version before the workflow later rejects it. Refresh the authoritative remote tag set before nextStableRelease / nextPreviewRelease, or resolve directly from the remote, and add a release-helper regression where local tags are stale but origin has a newer tag.

  2. The canonical contributing guide still begins the release procedure with bun run release .... This PR changes that contract: dev-version-bump.yml must be dispatched and its PR merged before promotion and release. A maintainer following the current page can push a release commit before learning that the pre-move was omitted. Add the dispatch, reviewed merge, and promotion order before the helper commands, and keep every translated page consistent with the English source.

The existing exact-head CI is green, but it does not make these ordering gaps safe. Please address both and request review again on the new head. I am not treating the separate protected-environment observation as introduced by this PR; the mutable release-ref trust model predates this change and can be evaluated independently.

Every release forces `dev` to catch up. `dev-version-bump.yml` records four hand
repairs in its own header, history shows "move dev to 2.4x.0" once per release, and
while `dev` trails the highest tag `tests/release-version-line.test.ts` fails on `dev`
AND on every open pull request — an inherited red a contributor cannot fix from their
own diff. This unit designs the fix; no production file changes.

ima2-gen solves the same problem with one atomic push of main+dev+tag, which is not
portable here: `Protect dev` requires review and code-owner sign-off, and trading
branch protection for chore removal is a bad exchange.

What the design landed on, after the audit forced two retractions:

- The per-release `dev` commit CANNOT be deleted. It is structural, following from
  `Protect dev` + `release.ts:494` allowedBranches + a monotonically advancing tag
  set. The first draft claimed otherwise and was wrong.
- So the commit MOVES instead: the pre-move opens and merges the version PR BEFORE
  the release rather than after it. Same count of reviewed commits, no red window.
- Ancestry is explicitly NOT a property this design maintains. An earlier draft
  asserted it; `release.ts:559-591` creates the release commit after promotion, so it
  is a descendant and can never be an ancestor. The assertion was withdrawn along
  with the test that would have enforced it.
- Option A rides along: `--bump patch|minor|major` replaces a hand-passed version,
  with channel-specific algebra so a future preview tag cannot drag a stable bump
  onto the wrong core.
- Publishing a preview for a higher core CLOSES the older stable patch line. This is
  a deliberate policy restriction, enforced at the publication boundary rather than
  only in the helper, and it is recorded as policy because history contains real
  counterexamples where a lower stable patch shipped after a higher-core preview.

Six audit rounds: FAIL(5) -> FAIL(2) -> FAIL(3) -> FAIL(2) -> FAIL(1) -> PASS. Each
blocker was verified against real code before folding, not relayed on trust. The
measurements that changed the design are recorded in `000_research.md` §11 so the
next reader does not re-derive a retracted claim.
…n-line.ts

The repository ordered releases in two places that could not agree, and only one
of them was reachable from a test. `compareReleaseVersions` lives in
`scripts/release.ts`, which parses argv and calls `process.exit` at module scope,
so importing it from a test kills the runner — it was exercised only through a
subprocess fixture.

The new module is pure at module level, which is the whole point: it is importable.

The two comparators stay deliberately different, and a test now pins that:

- `compareVersions` THROWS on unparseable input, because a release decision must
  fail closed. `release.ts:305-307` records that `Number()` on a garbage core once
  yielded NaN and made the forward guard accept any candidate.
- `compareTagsLenient` falls back to numeric-aware locale compare, exactly as
  `release-notes.ts` does today. Collapsing the two would be a live regression:
  `build-release-changelog.ts` admits any `/^v\\d/` tag, so one malformed historical
  tag would newly abort release-note generation.

Both assertions live in one test so the distinction cannot be optimised away later.

`nextDevelopmentVersion` moves here from `bump-dev-version.ts`. Its prerelease row
is load-bearing rather than an edge case: the rule was once written as "increment
the released minor", and befcac3 disproves it — a published `X.Y.Z-preview.*`
means the stable core has not shipped, so dev should carry `X.Y.Z`, not `X.(Y+1).0`.

`tests/bump-dev-version.test.ts` is unchanged and still green. That is the proof the
extraction was faithful, and it was this phase's primary gate.

Verification (focused only; the repository-wide suite was deliberately not run):
  bun test tests/version-line.test.ts          7 pass
  bun test tests/bump-dev-version.test.ts     10 pass, file unchanged
  bun test tests/release-notes.test.ts        71 pass
  bun test tests/release-version-line.test.ts  3 pass
  bun test tests/release-helper.test.ts       33 pass
  bun run typecheck                           exit 0

Both new assertions were proven red before the implementation by mutation: the
collapsed comparator threw where the lenient one must not, and the prerelease row
returned 2.37.0 instead of 2.36.0.

Design: devlog/_plan/260904_release_version_line/010_phase1_version_algebra.md
Phases 020 and 030 of devlog/_plan/260904_release_version_line/, implemented in
parallel and committed together because they share scripts/version-line.ts.

020 — `--bump patch|minor|major`

The maintainer no longer hand-passes a version string. Two resolvers keep the
channels apart, which the audit required: a single global floor would let a future
v2.43.0-preview.1 turn `--bump minor` into 2.44.0 and skip the intended 2.43.0.

- nextStableRelease derives from the stable channel and tags only. A future
  same-core preview may validate the target core but never raises the base, and a
  patch bump is REFUSED outright when a preview tag sits above the base — publishing
  a preview for a higher core closes the older stable patch line.
- nextPreviewRelease picks a core outranking the latest stable, then a prerelease
  outranking existing preview tags. Succession comes from the incumbent, so an equal
  stamp increments its ordinal (.3 becomes .4) and an older stamp is an explicit
  clock-regression error rather than a silently behind candidate.

030 — the dev version PR opens BEFORE the release

dev-version-bump.yml stops being a repairer and becomes an opener. The count of
reviewed commits into dev is unchanged — that is structural, since Protect dev
requires review — but the window in which dev and every open PR carry a red they
cannot fix disappears.

- workflow_call is deleted together with its only caller, the bump-dev-version job
  in release.yml. A repository-wide search found no second caller.
- One normalized target version is resolved before the decision step, so no
  downstream consumer reads a raw event input.
- The chosen-version freeness check is RETAINED and the target-availability check is
  added alongside it. Replacing it would have dropped candidate-collision protection.
- release.yml gains a readiness gate and an ordering gate. The ordering gate runs
  after the fresh tag fetch — before it, the stale tag set would defeat the point —
  and --allow-existing-tag-at-head is granted only for a dry run whose tag names the
  exact SHA, preserving the deliberate exception that already lived there.

Verification, per phase, focused files only:
  020: version-line 20 pass, release-helper 39 pass, release-version-line 3 pass,
       typecheck exit 0, privacy:scan passed, docs-site build 425 pages
  030: ci-workflows 136 pass, bump-dev-version 14 pass, version-line 20 pass,
       typecheck exit 0

Red-before proofs: 020's resolver suite failed on the higher-core patch refusal and
the equal-stamp succession before implementation; 030's ordering assertion fails
when the gate is moved ahead of the tag fetch and passes when restored.

MAINTAINERS.md still describes the old post-release flow. That correction belongs to
phase 040 and is deliberately not in this commit.
…line policy

Phase 040 of devlog/_plan/260904_release_version_line/. Documentation only; no
assertion, script or workflow changes.

MAINTAINERS.md told maintainers to move dev's version line while CLOSING a release.
Done at closing time it is always too late, and that instruction is the cause of the
recurrence it warns about — four hand repairs, and a detector that did not stop two
more. It now says the opposite: opening a release STARTS by moving dev forward, dev
must already outrank the version being released, and release.yml refuses to publish
otherwise. The historical repair record stays, because it is why the rule exists.

The SoT gains the policy the code now enforces: publishing a preview for a higher
core ends the current stable patch line, and nextStableRelease refuses such a patch
bump. This is a deliberate restriction, not the preservation of an unused capability
— history contains real counterexamples (v2.6.24-preview.20260705 then v2.6.23,
v2.7.39-preview.20260724 then v2.7.37), and 103 of 143 stable tags carry patch > 0.
Recording it as policy is what keeps a future reader from re-deriving that as a bug.

tests/release-version-line.test.ts gains two comment lines and nothing else. Its
assertions are byte-identical and tagPointsAtHead is retained: the release commit
still equals its own tag. An earlier draft proposed asserting
compareReleaseTags("v2.42.0", "v2.42.0") === 0 — that is tautological, exercises the
comparator rather than the exception, and would pass against a build that deleted
the exception entirely. It was rejected in audit and is not here.

Verified by diff inspection rather than execution: local test and typecheck runs are
prohibited for this work, and the change set is being verified on CI instead.
