## Task Description

Hotfix a governance regression from #188: bootstrap's recommended CLI helper writes its own short-lived PID into advisory Work Log locks, causing a second CLI run to treat a fresh non-stale lock as `dead-pid` and overwrite it instead of surfacing active-lock risk.

## Phase Sequence

| Phase | Status | Entered | Notes |
|---|---|---|---|
| bootstrap | completed | 2026-06-08 | Classified as hotfix; branch and Work Log created. |
| plan | completed | 2026-06-08 | Minimal fix: CLI must not write helper PID by default; add regression. |
| implement | completed | 2026-06-08 | CLI omits pid by default; explicit `--pid` owner PID added. |
| review | completed | 2026-06-08 | PASS after expert finding integrated. |
| test | completed | 2026-06-08 | Focused, adjacent, guard suite, py_compile, PowerShell/Git Bash validators passed. |
| ship | completed | 2026-06-08 | SSoT/archive updated; final validation pending rerun after archive. |

## Phase Summary

- bootstrap: selected hotfix after post-merge simulation found CLI-created locks are immediately recoverable as `dead-pid`. ⚡ ACX
- plan: Target Files: `.agentcortex/tools/recover_worklog_lock.py`, `tests/guard/test_worklog_lock_recovery.py`, `.agent/workflows/bootstrap.md`; optional SSoT/archive updates at ship. Steps: red regression → minimal CLI PID semantics fix → expert review integration → focused/full validators → ship. Rollback: revert PR. ⚡ ACX
- implement: Changed CLI PID semantics: default omits pid; explicit owner PID uses `--pid <owner-pid>`; API default `include_pid=False`; bootstrap docs updated. Red regression added for CLI A→CLI B immediate active preservation. ⚡ ACX
- review: Verdict PASS. Expert Goodall found `--include-pid` footgun and API default inconsistency; both fixed by replacing it with explicit `--pid` and default no-pid. Red-team: no dependency/auth surface; active-lock bypass regression covered. ⚡ ACX
- test: PASS. Focused 8 OK; adjacent 32 OK; guard suite 140 passed; PowerShell and Git Bash validators both `pass=101 warn=7 fail=0 skip=2`; `git diff --check` PASS. ⚡ ACX
- ship: SSoT Ship History updated via guarded write; Work Log archived and INDEX append planned; rollback remains revert PR. ⚡ ACX

## Known Risk

- Risk: preserving active locks too aggressively could slow recovery from truly abandoned sessions; mitigation: timestamp staleness still recovers, and explicit PID can remain opt-in for trusted long-lived callers.
- Risk: advisory locks are not hard locks; mitigation: this hotfix restores warning/exit semantics, not hard-blocking.
- Rollback plan: revert PR.

---

## Conflict Resolution

- systematic-debugging controls root-cause evidence before patching; test-driven-development controls red/green regression; red-team checks bypass paths; verification-before-completion gates final claims.

---

## Skill Notes

- Applying systematic-debugging strategy.
  - Checklist: MRE before patch; isolate CLI-created PID path.
  - Checklist: verify one-variable fix and preserve explicit live-PID behavior.
  - Constraint: no random rewrite of lock model.
- Applying test-driven-development strategy.
  - Checklist: add failing CLI A then CLI B regression first.
  - Checklist: keep tests in existing `tests/guard/test_worklog_lock_recovery.py`.
  - Constraint: no production change without regression.
- Applying verification-before-completion strategy.
  - Checklist: scope, quality, evidence, risk, communication before completion.
  - Checklist: include local validators and CI/PR status.
  - Constraint: no completion claim without command output.

## Drift Log

- Expert review: Goodall flagged public `--include-pid` as a footgun and API `include_pid=True` as inconsistent with advisory Work Log locks; integrated by using explicit `--pid <owner-pid>` and default no-pid.

---

## Security Findings

none

---

## Red Team Findings

- 2026-06-08 /review: 0 unresolved findings. Prior MEDIUM footgun (`--include-pid` writes helper PID) removed; explicit `--pid` now requires caller-supplied owner PID.

---

## Evidence

- MRE: CLI A creates lock, CLI B immediately recovers it as `dead-pid`; final owner becomes agent-b.
- Red: `python -m unittest tests.guard.test_worklog_lock_recovery -v` -> FAIL in `test_cli_created_lock_is_preserved_until_stale` because CLI wrote helper `pid`.
- Green: `python -m unittest tests.guard.test_worklog_lock_recovery -v` -> PASS: 8 tests OK.
- Adjacent: `python -m unittest tests.guard.test_d2_1_guard_unit tests.guard.test_worklog_lock_recovery -v` -> PASS: 32 tests OK.
- Syntax: `python -m py_compile .agentcortex/tools/recover_worklog_lock.py tests/guard/test_worklog_lock_recovery.py` -> PASS.
- Guard suite: `python -m pytest tests/guard -q` -> PASS: 140 passed.
- Validators: `powershell -ExecutionPolicy Bypass -File .agentcortex/bin/validate.ps1` -> PASS: `pass=101 warn=7 fail=0 skip=2`.
- Validators: `C:\Program Files\Git\bin\bash.exe .agentcortex/bin/validate.sh` -> PASS: `pass=101 warn=7 fail=0 skip=2`.
- Diff: `git diff --check` -> PASS.
