Summary

  • Purely relocate the existing status health and stale-process probes into src/cli/status-probes.ts; preserve the original public import path and all 11 exports. No new diagnostic behavior is introduced.
  • Reduce src/cli/status.ts from 547 to 384 lines; the new probe leaf has 168 lines. Keep the existing per-call timeout, refusal classification, recorded-port choice, and before/after snapshots unchanged.
  • The unchanged 215-line collectStatus function remains function-level debt; this layer resolves the file boundary only.
  • Add forwarding-identity and private-helper-exclusion assertions to the existing status tests, preserving every original assertion. Update the Runtime ownership row and numbered plan.
  • Source churn is 341 lines, including 163 relocated lines and one accounted terminal-separator cleanup. The parent-relative implementation is two source files, one existing test, and one ownership row.
  • Reconcile the carried shared-plan rules: chain only declared dependencies, exclude class/method-only semantics from the factory exception, and judge unresolved function debt from the final residual rather than a 350-line shortcut.

S14 layer map

Layer Branch Base Status
450, this PR codex/split-cli-status dev verified; landing pending
460 codex/split-cli-provider dev planned independently
470 codex/split-client-hub-client dev planned independently

The other S14 layers are not prerequisites. Verified prerequisite #3640 and subsequent #3626/#3636/#3645 changes have already landed on dev. This branch consumes that published base, without the unmerged WS #3643 candidate. Owner-authorized admin landing will occur only after this PR's fresh checks and review disposition; it is not a CI waiver or self-approval.

Verification

  • Candidate HEAD: df92323d3406535c7eacd0bfa2d5bae6adb610e1; verified integration base: 45f3bed84be10a7e045a20aae1db46ab822bf7d0.
  • Independent plan/content and operational audits passed. The actual integration's source/test/architecture content matches the reviewed candidate. All three owned source/test blobs match the original approved extraction; the import-graph review preserves 11 exports and finds no return cycle through either status module.
  • git diff --check, owned blob comparisons, source line counts, parent-relative change accounting, and verification-script Bash syntax checks passed. No local suite, typecheck, or dependency install ran.
  • Fresh independent static implementation/security review passed at this HEAD: all 15 declarations have one owner, 51 named import/re-export bindings resolve, original tests remain, and no source or documentation scope drift was found.
  • The three retained documentation findings were corrected together and independently re-reviewed. Prior source HEAD 8bc931e3 passed CI 33962861576; the new commit changes only three documents, and that earlier run is not final-head proof.
  • Final-head Cross-platform CI 33963307005 passed: 18 successful jobs and two configured dispatch-only skips. Linux and macOS tests actually executed.
  • In a fresh isolated remote checkout of this exact HEAD, repository Bun 1.4.0 build preparation, bun run typecheck, the three planned focused files (50 pass), bun run privacy:scan, and bun run test passed. Full suite: 18,842 pass / 16 skip / 0 fail, including all six disjoint serial lanes. The bound receipt records exit 0 and a clean final HEAD.
  • Both planned remote mutation controls failed on their intended named case (exit 1), then restored to 27 pass / 0 fail each. The final remote tree remained clean at this HEAD.
  • Fresh independent C evidence review passed, including exact source/receipt identity, full-suite accounting, negative activation/restoration, and hosted CI. The tested integration commit is 1ce6ae480b5e54ba8356f198f53e12d4bfcd3cb4, tree 7ffe001817a487a47f5836eedfe1645574111393, identical to the PR HEAD tree.
  • Earlier 4a71894, 8bc, and prerequisite results remain historical; none substitutes for these final-head gates. No local suite, release, or live-service change is included.

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

  • New Features

    • Improved status and doctor diagnostics for proxy health and stale processes.
    • Health checks now validate the expected response and provide clearer failure details.
    • Stale-process detection uses recorded runtime information and confirms port availability before reporting unclean exits.
  • Documentation

    • Updated runtime documentation to clarify status and health-probe behavior.
  • Tests

    • Added coverage ensuring status commands consistently expose their health-diagnostic capabilities.

📝 Walkthrough

Walkthrough

The change updates split-train rules and extracts CLI health and stale-process probes from src/cli/status.ts into src/cli/status-probes.ts. The status facade preserves its public exports. Tests verify forwarding identity and helper visibility.

Changes

CLI status split

Layer / File(s) Summary
Split-train governance
devlog/_plan/260905_now_split_train/000_plan.md, devlog/_plan/260905_now_split_train/003_parent_decisions.md
The plans define residual-file exceptions, method extraction limits, branch dependency rules, admin landing requirements, and final verification evidence.
Status probe extraction design
devlog/_plan/260905_now_split_train/450_cli_status.md
The CLI plan assigns probe logic to status-probes.ts, retains status assembly in status.ts, preserves public exports, and records verification and integration criteria.
Probe module implementation
src/cli/status-probes.ts, src/cli/status.ts
The new module adds failure classification, connection-refusal detection, stale-process evidence checks, timed proxy health checks, and runtime snapshot probing. status.ts imports the shared probes and re-exports the public helpers and ListenTarget.
Compatibility validation and ownership
tests/cli/cli-status-json.test.ts, structure/01_runtime.md
The test verifies forwarding identities and confirms that checkProxyHealth remains private. Runtime documentation records ownership for both modules.

Estimated code review effort: 4 (Complex) | ~45 minutes

Merge Risk: ⚪ Minimal · up to df923

This refactor moves CLI health and stale-process probes into a shared module while preserving status behavior and the existing facade boundary. The supplied compatibility coverage supports merge readiness with no identified production risk.

리뷰 · 우선순위 42 / 80

이 PR은 S14 1/3로, src/cli/status.ts 안의 health/stale-process 프로브를 새 파일 src/cli/status-probes.ts로 옮기고 residual은 조립·re-export만 남기는 순수 이동 리팩터입니다. 공개 import 경로는 유지하고, 기존 CLI status 테스트에 forwarding 단언을 더합니다. PR 본문도 “merge 요청 없음 / 이 diff만 리뷰”라고 적어 두었습니다.

현재 dev HEAD a687eb735에서 status.ts는 아직 547줄이고 status-probes.ts는 없습니다. 계획 문서(devlog/_plan/260905_now_split_train/450_cli_status.md)와 구조 표(structure/01_runtime.md)까지 같이 온 점은 분할 캠페인 습관과 맞습니다. base는 dev이고 draft입니다. 부모 베이스가 본문 기준 9fe986d84(#3552)라 HEAD보다 뒤입니다. 지금 당장 랜딩할 물건은 아니고, 검증·CI 모으는 중인 레이어로 보면 됩니다.

이동 범위(헬퍼 export 유지, checkProxyHealth는 residual 전용, 타이머/finally·connect-refusal·recorded-port 스냅샷 보존)는 설명이 구체적입니다. “동작 변경 없이 파일만 쪼갠다”면 우선순위는 기능 버그보다 낮고, Windows Offline(#3634)이나 quota/onboarding 트레인보다 급하지 않습니다. 다만 status/doctor가 같이 쓰는 프로브라서, 실수 re-export 누락은 바로 CLI 진단 깨짐으로 갑니다.

src/cli/status-probes.ts (신규) - 168줄 leaf. public surface에 checkProxyHealth를 새로 올리지 말라는 계획과 맞는지 CI/테스트에서 한 번 더 확인하세요.
src/cli/status.ts - re-export 블록과 내부 import가 어긋나면 doctor/status 소비자가 깨집니다. 기존 11 export 보존이 머지 조건입니다.
base vs HEAD - 부모 베이스가 a687eb735보다 뒤처져 있습니다. 랜딩 전에 dev 재기반이 필요합니다.
본문 - merge/auto-merge 요청 없음. draft 유지가 맞습니다.

메인테이너의 판단이 필요한 지점

  • S14 450을 지금 머지 트레인에 squish할지, 460/470과 같이 묶어서 볼지
  • “검증 수집 중”인 동안 draft로만 둘지

너의 추천
지금은 머지하지 말고 draft로 두세요. exact-head CI·mutation control·export identity 검증이 초록이면 dev에 rebase한 뒤 S14 1/3로 단독 랜딩해도 됩니다. 기능 우선순위(#3634 등)보다 뒤로 두세요.

In `@devlog/_plan/260905_now_split_train/000_plan.md`:
- Around line 40-42: Update the Git topology guidance in the plan so upper-layer
branches use the branch below only for explicitly declared dependency edges;
independent layers must use dev as their base. Remove or explicitly mark the
blanket parent-branch rule as superseded, preserving the existing branch naming
and merge restrictions.

In `@devlog/_plan/260905_now_split_train/003_parent_decisions.md`:
- Around line 62-63: Update
devlog/_plan/260905_now_split_train/003_parent_decisions.md lines 62-63 to
require RESIDUAL-FN selection only when the final residual exceeds 400 lines and
one unsplittable function is the sole cause; update
devlog/_plan/260905_now_split_train/000_plan.md lines 25-27 to replace the
blanket successor requirement with the explicit RESIDUAL-FN-01 exception.
- Around line 36-41: Restrict the method-to-factory transformation described
near createAnthropicAdapter to object-literal methods only; do not apply it to
class methods. Preserve methods using super or private-name references, and
retain class prototype dispatch rather than replacing methods with own
properties.

Owner-authorized admin approval bypass, not self-approval or a CI waiver. Exact head df92323 passed Cross-platform CI33963307005 (18 successful jobs, two configured skips), current metadata gates, and fresh independent C review. Isolated remote verification passed build/typecheck, 50 focused tests, privacy scan, and the full suite (18842 pass/16 skip/0 fail); both named negative controls failed as intended and restored to 27/27 with clean exact-head proof. Actual tested merge1ce6ae480b5e54ba8356f198f53e12d4bfcd3cb4/tree7ffe001817a487a47f5836eedfe1645574111393 was re-fetched and matches. Current dev45f3 is unchanged and there are no open direct children or unresolved review threads. External CodeRabbit is still optional/PENDING at this snapshot and is not counted as PASS; independent review and all executable gates are complete. Landing with explicit expected-head match. No release or live-service change.
