fix(codex): map the collaboration_mode prompt layer

[luvs01]

Summary

• The prompt-text probe listed collaboration in UNMAPPED_LAYER_IDS, so a rendered <collaboration_mode> section was reported as unmapped even though Codex wraps collaboration instructions in that tag when the active mode emits them.
• Map collaboration to collaboration_mode in LAYER_SECTION_TAGS and extract the section-to-layer projection into a testable mapSectionsToLayers seam.

Verification

• bun test tests/codex-integration/codex-prompt-text-probe.test.ts (43 pass, 1 pre-existing skip)
• bun x tsc --noEmit

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

• Bug Fixes

  • Collaboration content is now correctly recognized when rendered, including its text and size.
  • Empty collaboration sections now report as not rendered instead of unmapped.

• Tests

  • Added coverage for rendered and absent collaboration sections.

📝 Walkthrough

Walkthrough

The prompt text probe now maps the rendered collaboration_mode section to the collaboration layer. The mapping logic is reusable through a test seam, and integration tests cover rendered and absent sections.

Changes

Collaboration prompt projection

Layer / File(s)	Summary
Collaboration tag mapping src/codex/prompt-text-probe.ts	LAYER_SECTION_TAGS maps collaboration to collaboration_mode. collaboration is removed from UNMAPPED_LAYER_IDS.
Section projection and validation src/codex/prompt-text-probe.ts, tests/codex-integration/codex-prompt-text-probe.test.ts	mapSectionsToLayers replaces the inline projection in probePromptText and is exported through mapSectionsToLayersForTests. Tests verify rendered text, byte length, and the not-rendered result for an absent section.

리뷰 · 우선순위 34 / 80

이 PR은 프롬프트 텍스트 프로브가 collaboration 레이어를 잘못 “매핑 없음(unmapped)”으로 보고하던 버그를 고칩니다. Codex가 협업 모드 안내를 실제로 넣을 때 <collaboration_mode> 태그로 감싸는데, 프로브 표에는 그 태그가 없고 UNMAPPED_LAYER_IDS에만 collaboration이 있어서, 화면에 글자가 있어도 “이 레이어는 아직 못 읽는다”고 나왔습니다.

이번 변경은 세 가지입니다. 첫째, LAYER_SECTION_TAGS에 collaboration → collaboration_mode를 넣습니다. 둘째, UNMAPPED_LAYER_IDS에서 collaboration을 뺍니다. 셋째, 섹션→레이어 매핑을 mapSectionsToLayers로 빼서 테스트에서 바로 확인할 수 있게 합니다. 테스트는 태그가 있을 때 본문·바이트가 맞고, 없을 때 not-rendered가 나오는 두 경우를 봅니다. 베이스는 dev입니다. 인벤토리 문서에도 Collaboration mode 태그가 <collaboration_mode>로 적혀 있어, 태그 이름 자체는 저장소 근거와 맞습니다. types.ts/config.ts 분할과 무관하고, 같은 주제로 닫을 다른 열린 PR도 보이지 않습니다.

라인 - src/codex/prompt-text-probe.ts LAYER_SECTION_TAGS.collaboration — 태그 이름은 인벤토리(001_prompt_layer_inventory.md)와 맞습니다. 다만 이 PR 본문에는 이번 머리에서 찍은 codex debug prompt-input 원문 조각은 없습니다. 파일 머리 주석 관례(“라이브 출력에서 읽었다”)를 믿는 수준입니다.
라인 - mapSectionsToLayers — 태그는 있는데 trim 후 본문이 비면 reason: "ok"에 빈 문자열입니다. 다른 매핑 레이어와 같은 기존 규칙이고, 이번 PR이 새로 만든 구멍은 아닙니다.
라인 - PR 체크리스트 — 네 칸이 모두 비어 있습니다. 코드 결함이라기보다 머지 전 절차가 아직입니다.
라인 - CI — 이 글을 쓰는 순간 label은 통과, enforce-target·hygiene는 대기였습니다. 초록을 한 번 더 확인하는 편이 좋습니다.

메인테이너의 판단이 필요한 지점

인벤토리·기존 empirical 메모만으로 collaboration_mode 매핑을 확정할지, 아니면 한 번 라이브 prompt-input 캡처를 PR에 붙여 달라고 할지. 협업 모드가 안내를 안 내는 환경에서는 계속 not-rendered로 보이는데, 그걸 UI에서 “꺼짐”과 어떻게 구분해서 설명할지(이미 다른 컨텍스트 의존 레이어와 같은 문제)는 제품 쪽 선택입니다.

너의 추천

방향이 맞고 범위도 좁습니다. 매핑·테스트 seam·회귀 테스트가 한 줄로 맞물려 있어서, CI가 초록이고 체크리스트를 채운 뒤 dev에 머지해도 됩니다. 라이브 캡처는 있으면 안심이 되지만, 없어도 이 PR을 막을 정도는 아닙니다. types/config 분할로 닫을 대상이 아닙니다.
