Summary

Follow-up to #4276, closing the review findings on the SSOT gate. CodeRabbit posted twelve findings;
these are the ones still true against the merged code.

The gate was claiming more than it checked in four places:

  • A fragment-only link was skipped entirely — and one was already broken. structure/subagents.md
    pointed at #ultra-reasoning-level, a heading that moved to catalog.md during the split. Fragment
    targets now resolve against their own document, which found it on the first run.
  • Link targets were resolved with existsSync while backticked paths went through the git index. That
    is exactly the per-machine split verdict this module exists to remove, applied to the reference
    class this change churned hardest.
  • A documents entry was accepted because the path existed, not because the doc said anything about
    it, so the map could claim coverage the prose did not have. A claim now has to be backed by a path
    the doc actually names.
  • Decision-record ownership was inferred from any occurrence of the filename in raw text, so a record
    path inside a fenced example counted as a second owner, and an orphaned record whose owner link had
    been deleted still looked owned. Ownership is now the > Decision record: link, read fence-stripped.

Also fixed: the filesystem fallback no longer applies when the git index is readable, so untracked
local leftovers cannot satisfy a check CI will fail; the manifest goes through a validating loader,
so a malformed file is a failure line instead of an uncaught stack trace; a missing overview.md is a
failure rather than silence across every invariant binding; and backticked paths rooted at any
tracked top-level entry are checked, not only the ten directories that were hardcoded.

One finding is answered rather than implemented. Validating every filename-shaped token would
reject the runtime files these docs legitimately name — config.toml, models_cache.json, ocx.pid —
which live in a user's home, not in this repository. The boundary is now stated in
structure/AGENTS.md, and root documents stay covered because a reference like MAINTAINERS.md is
written as a link, and links are checked.

Docs: the rationale left inline in structure/adapters/registry.md moves into ADR-0093 with its
evidence intact. All 96 records are retitled to say what they are — the heading names the section a
record was extracted from, not the decision it contains, and a title that reads like a decision name
while being a section name sends maintainers to the wrong record. src/AGENTS.md now says every
applicable doc is updated, not one.

Not carried here: the ADR-0077 finding about binding update-worker liveness to a job identity is a
runtime defect in the update path, not a documentation problem, and does not belong in a docs PR.

Verification

  • bun run typecheck
  • bun run structure:check
  • bun run privacy:scan
  • bun test tests/ci-workflows/structure-ssot.test.ts — 33 pass, six of them new, including the two
    cases that must NOT fire: a bare filename is not a repository path, and a record named in prose is
    not an owner

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.

Summary by CodeRabbit

  • Documentation

    • Clarified how source areas map to multiple supporting documents.
    • Updated decision-record headings to identify their documented topic.
    • Corrected an internal documentation link for Ultra reasoning levels.
    • Added guidance covering staged files, document coverage, links, manifests, and required overview documentation.
    • Expanded decision-record documentation explaining schema safety limits.

  • Bug Fixes

    • Structure validation now reports actionable errors for malformed manifests, missing documentation, invalid links, and incomplete source-area coverage.
    • Validation more accurately recognizes repository paths and decision-record ownership.
    • Added broader coverage for filesystem, Git-index, and malformed-input validation scenarios.

bedbfb4 
Follow-up to #4276. CodeRabbit posted twelve findings on that PR; these are the ones that were
still true against the merged code.

The gate was claiming more than it checked, again, in four places:

- A fragment-only link was skipped entirely, and one was already broken: structure/subagents.md
  pointed at #ultra-reasoning-level, a heading that moved to catalog.md during the split. Fragment
  targets now resolve against their own document, which found it immediately.
- Link targets were resolved with existsSync while backticked paths went through the index. That is
  the per-machine split verdict this module exists to remove, on the reference class the split
  churned hardest.
- A documents entry was accepted because the path existed, not because the doc said anything about
  it, so the map could claim coverage the prose did not have. A claim now has to be backed by a path
  the doc actually names.
- Decision-record ownership was inferred from any occurrence of the filename in raw text. A record
  path inside a fenced example counted as a second owner, and an orphaned record whose owner link
  was deleted still looked owned. Ownership is now the > Decision record: link, read fence-stripped.

Also: the filesystem fallback no longer applies when the git index is readable, so untracked local
leftovers cannot satisfy a check that CI will fail; the manifest goes through a validating loader so
a malformed file is a failure line instead of an uncaught stack trace; a missing overview.md is a
failure rather than silence across every invariant binding; and backticked paths rooted at any
tracked top-level entry are checked, not just the ten directories that were hardcoded.

One finding is answered rather than implemented. Validating every filename-shaped token would
reject the runtime files these docs legitimately name - config.toml, models_cache.json, ocx.pid -
which live in a user's home, not in this repository. The boundary is now stated in
structure/AGENTS.md, and root documents stay covered because a reference like MAINTAINERS.md is
written as a link, and links are checked.

Docs: the client-integration rationale left inline in adapters/registry.md moves into ADR-0093 with
its evidence intact. All 96 records are retitled to say what they are - the heading names the
section a record was extracted from, not the decision it contains, and a title that reads like a
decision name while being a section name sends maintainers to the wrong record. src/AGENTS.md now
says every applicable doc is updated, not one.

Six new negative cases, including the two that must NOT fire: a bare filename is not a repository
path, and a record named in prose is not an owner.

📝 Walkthrough

Walkthrough

The structure gate now validates manifest shape, indexed repository paths, links, source-to-document coverage, overview presence, and explicit decision-record ownership. Documentation, ADR titles, link references, and regression tests were updated to match these rules.

Changes

Structure SSOT validation

Layer / File(s) Summary
Manifest and path validation
scripts/structure-ssot.ts, structure/AGENTS.md		 Adds exported loadManifest, actionable manifest errors, git-index path checks, root-entry detection, and scoped backticked path validation.
Link and coverage invariants
scripts/structure-ssot.ts, structure/subagents.md		 Validates fragment-only links, explicit decision-record links, overview presence, and source-area path coverage.
Validation regression tests
tests/ci-workflows/structure-ssot.test.ts		 Adds coverage for malformed manifests, invalid fragments, missing overview files, undocumented areas, prose-only ADR references, bare filenames, indexed paths, and malformed grace elements.
Documentation contract alignment
src/AGENTS.md, structure/AGENTS.md, structure/adapters/registry.md		 Updates guidance for staged files, bidirectional documentation coverage, link resolution, manifest checks, root-entry boundaries, decision-log markers, and normalization documentation.
Decision-record title normalization
structure/decisions/*		 Rewords ADR headings to identify the documentation section under which each decision was recorded. ADR-0093 adds the “Why three budgets” explanation.

Priority: ⬇️ Low

Estimated code review effort: 3 (Moderate) | ~25 minutes

Change: Bug fix

Merge Risk: 🔵 Low · up to 6d890

The structure gate can still accept documentation coverage for a file area when only a similarly prefixed sibling is named. This is a bounded validation gap and can be addressed as follow-up work.

리뷰 · 우선순위 71 / 80

이 PR은 방금 dev에 들어간 #4276(docs(structure): restructure the maintainer SOT and gate it mechanically, HEAD bd1864905, package 2.52.0)의 후속이다. #4276이 structure/를 주제 문서 + structure/manifest.json + scripts/structure-ssot.ts 게이트로 다시 짠 직후, 게이트가 “검사한다고 말해 놓고 실제로는 안 보는” 구멍이 네 군데 남아 있었다. 이 PR은 그 구멍을 닫고, CodeRabbit이 지적한 항목 중 문서 게이트 범위에 남는 것만 반영한다. 런타임 제품 코드는 건드리지 않는다.

지금 dev의 게이트는 이미 INDEX 생성, 소유권, 크기, 링크, INV-* 바인딩을 기계적으로 본다. 그런데 네 가지가 거짓 초록을 만들 수 있었다. (1) #heading만 있는 링크는 통째로 건너뛰었다. 실제로 structure/subagents.md가 #ultra-reasoning-level을 가리키고 있었는데, 그 제목은 분할 때 catalog.md로 옮겨져 깨진 상태였다. (2) 링크 대상은 existsSync로 보고 backtick 경로만 git index로 봐서, 이 모듈이 없애려던 “내 머신에만 있는 파일” 판정이 링크에 다시 생겼다. (3) manifest documents에 경로만 있으면 본문이 그 영역을 한 번도 안 말해도 통과했다. (4) ADR 소유권은 본문 어디에든 파일명이 보이면 인정해서, 펜스 안 예시나 이미 지워진 링크의 잔여 문자열이 “소유자”로 잡혔다.

이 PR의 핵심 수정은 scripts/structure-ssot.ts에 모인다. loadManifest가 JSON·필수 필드 모양을 먼저 검사해서 깨진 manifest는 스택 트레이스 대신 실패 한 줄이 된다. pathIsReal은 git index를 읽을 수 있으면 파일시스템 폴백을 쓰지 않는다. 링크도 같은 pathIsReal을 타고, fragment-only 링크는 자기 문서 heading에 대해 검사한다. ADR 소유권은 fence를 벗긴 뒤 > Decision record: 링크만 센다. documents 항목은 해당 문서가 그 영역 안의 경로를 실제로 인용할 때만 인정한다. backtick 경로 허용 범위는 하드코딩 10개 디렉터리 대신 “tracked top-level entry로 시작하는지”로 넓혔고, config.toml / models_cache.json / ocx.pid 같은 홈 런타임 파일은 일부러 검사하지 않는다는 경계를 structure/AGENTS.md에 적어 두었다. 빠진 overview.md는 모든 인변수 검사를 조용히 끄는 대신 바로 실패한다.

문서 쪽은 structure/adapters/registry.md에 남아 있던 Moonshot $ref 예산 근거를 structure/decisions/ADR-0093-...의 “Why three budgets”로 옮겼고, ADR 96개 제목을 decision recorded under "<section>" 형태로 맞춰 “섹션 이름인지 결정 이름인지” 헷갈리지 않게 했다. src/AGENTS.md는 한 영역이 여러 주제 문서에 걸칠 수 있으니 listed docs를 모두 갱신하라고 고쳤다. 테스트는 tests/ci-workflows/structure-ssot.test.ts에 음성 케이스 여섯 개를 추가했다. 특히 “bare filename은 repo path가 아니다”, “본문에만 적힌 ADR은 소유가 아니다”는 게이트가 과하게 울리면 안 되는 경계다. ADR-0077 update-worker 활성/잡 정체성 문제는 런타임 결함이라 이 docs PR에 안 실은 판단도 맞다.

types.ts/config.ts 분할 캠페인과는 충돌하지 않는다. 오히려 #4276이 남긴 grace.undocumentedSourceAreas의 src/types/ 자리를 그대로 두고, 게이트의 신뢰도만 올린다. CI는 hygiene/enforce-target 등은 이미 통과했고 전체 test/gates는 아직 도는 중이다. 머지 전에 structure:check 레인과 전체 스위트 초록만 보면 된다.

라인 460 - scripts/structure-ssot.ts의 n.startsWith(area) - 디렉터리 area에 trailing slash가 없으면 src/co가 src/codex/...를 덮어 쓸 수 있는 접두 충돌이다. 지금 manifest 디렉터리 항목은 slash가 있어 당장은 안전하지만, 앞으로 slash 없는 디렉터리 area가 들어오면 경계(area + "/")로 막는 편이 낫다.

라인 233-237 - scripts/structure-ssot.ts의 pathIsReal - git index가 읽히면 untracked 새 파일은 무조건 missing이다. structure/AGENTS.md에 “gate 전에 stage 하라”고 적어 둔 의도적 비용이지만, 로컬에서 문서+파일을 같이 쓰다가 stage를 잊으면 실패 원인이 한동안 안 보일 수 있다. 실패 메시지에 “untracked면 git add 필요”를 한 조각 넣으면 온보딩 비용이 줄어든다.

라인 439-448 - scripts/structure-ssot.ts의 namedByDoc - 경로 존재 검사(331행)는 rootEntries로 거르는데, coverage용 이름 수집은 pathRe 매치 전부를 넣는다. 지금은 area가 src/...라 실질 문제는 작지만, 두 경로의 필터를 같게 맞추면 이후 규칙 추가 때 어긋날 여지가 줄어든다.

경로/심볼 - ADR 제목 96개 rename - 읽기 명확성은 좋아지고, git blame/리뷰 diff 소음은 커진다. 내용 변경이 거의 없는 기계적 rename이라 리뷰 초점을 structure-ssot.ts + 테스트 + ADR-0093 본문 이동에 두는 게 맞다.

경로/심볼 - structure/subagents.md 134행 - 깨져 있던 #ultra-reasoning-level이 catalog.md#ultra-reasoning-level로 고쳐졌다. fragment-only 검사가 실제로 잡은 사례라 게이트 강화의 증거다.

메인테이너의 판단이 필요한 지점

  • CI 전체 초록을 기다린 뒤 바로 dev에 머지할지, CodeRabbit 잔여 코멘트까지 보고 한 번 더 손볼지
  • startsWith(area) 접두 경계를 이번 PR에서 고칠지, 후속으로 미룰지
  • untracked-missing 실패 메시지에 git add 힌트를 넣을지
  • ADR-0077 런타임 이슈를 별도 bug 티켓으로 지금 열어 둘지

너의 추천
전체 CI(특히 structure-ssot / structure:check 포함 레인)가 초록이면 바로 머지하자. #4276이 깐 게이트의 거짓 초록을 닫는 PR이라, 오래 열어 두면 그 사이에 새로 쌓이는 structure 문서가 다시 느슨한 규칙 위로 올라간다. startsWith 경계와 untracked 힌트는 머지를 막지 말고 follow-up 한 줄로 받아도 된다. close-don't-rebase 대상이 아니고, 제품 PR과 파일 충돌도 거의 없다.

P2 Badge Validate the manifest object and array elements

When manifest.json contains valid JSON with an invalid shape, this loader can still throw instead of returning an actionable failure: a top-level null crashes while evaluating m.sizeBudgetLines, while values such as generatedPaths: [null] pass these outer-array checks and later crash in trimSlash. Guard that the parsed value is a non-null object and validate each array element, including nested documents and grace records, before casting it to Manifest.

Reject invalid manifest roots and nested records before the cast.

🎯 Functional Correctness | 🟠 Major | ⚡ Quick win

Require a path-segment boundary for source coverage.

n.startsWith(area) accepts a sibling with the same prefix. For example, a claim for src/foo.ts passes when the prose names an existing src/foo.ts.bak, so the gate marks src/foo.ts as documented without citing it.

Compare exact paths or use n.startsWith(trimSlash(area) + "/") for directory descendants. Add a prefix-collision regression test.

matches and only accept descendants when the normalized area is followed by “/”,

@lidge-jun
docs(structure): answer the independent verification pass
6d890dd 
A second review, run separately from the agent that wrote the previous commit, found two ways the
gate was still wider than its prose and one it had newly opened.

Deriving the top-level path set from the tracked tree meant a reference became INVISIBLE exactly
when its directory disappeared. go/ is the live case: retired and untracked, so every remaining go/
mention had silently stopped being checked, and the absentPaths exemption that documents its absence
had become unreachable. The set now unions in the roots this repository has or used to have.

The mention-backed ownership check accepted the area name itself, which a table of directory names
satisfies - 32 of 105 claims rested on exactly that, including nearly every claim in runtime.md. The
check is unchanged; the prose is, because the honest description is that it catches an invented
claim and does not prove the doc says anything useful.

The manifest loader validated that grace arrays were arrays, never their elements, so a bare string
where an object belongs still threw a TypeError from inside the checks. Element shapes are validated
now. Source-area enumeration read the filesystem while every path resolved through the index, so an
untracked scratch directory under src/ produced a failure CI could not reproduce; it reads the index
too. Decision-record ownership matched on basename, so a link outside decisions/ could claim a record
it did not point at.

Also corrected in the rules file: the decision-log check finds two literal markers, not all inline
reasoning - the rationale moved out of registry.md last commit contained neither, which is the proof;
root files are checked directly rather than only through links; and the index comparison normalises
line endings rather than being byte-for-byte.

Five new cases, two of which build a real git repository, because every prior negative case ran in a
plain temp directory where the index branch - the one the module argues hardest for - was never
reached. One drives the case-variant verdict, one rejects an untracked leftover.

The gate checks the weak form of this: a `documents` entry is rejected when the doc never names the
area or any path under it. Naming the directory itself passes, which a table of directory names
does, so the check catches an invented claim but does not prove the doc says anything useful about
the area. That part is review.

Handle file and directory areas separately.

scripts/structure-ssot.ts:499 uses n.startsWith(area) for both area types. Directory areas include a trailing /, but file areas such as src/config.ts do not. A named path such as src/config.tsx can therefore satisfy src/config.ts and produce a false green result. Match n === trimSlash(area) for files, and allow trimSlash(area) + "/" descendants only for directory areas. Add a regression case for this file-prefix collision.
