1. Executive Summary

Branch fix/issue-10-11-13-15 resolves issues #10, #11, #13, and #15 while integrating peer-review feedback across two review loops.

In loop 1 (round 1), codex identified two edge cases:

• R1: agy in-use check passed only the main DB file to lsof, missing processes holding open the presence lock (or sidecars) without the UUID in command line arguments or environment variables.
• R2: Orphaned leftovers (e.g. WAL, annotations, or presence lock surviving after an interrupted or pre-#10 purge where the main DB was already gone) failed to resolve as a purge target because resolution relied on DB existence.

Commit fae70c1 directly resolves both codex findings through:

1. AgyAgentAdapter.conversation_in_use: Passes all conversation paths (_artifact_paths: DB, sidecars, brain, annotation, presence lock) to lsof -t.
2. AgyAgentAdapter.has_artifacts: Recognizes any existing artifact piece even if the primary DB has already been deleted.
3. BaseAgentAdapter.has_artifacts: Replaces the resolver's ad-hoc path fallback with a clean polymorphic method defaulting to uuid in path and os.path.exists(path), correctly preventing opencode (shared DB) from falsely claiming non-opencode UUIDs.

Together with caller session recognition (7610258) and dynamic test fixtures (f5a6575), the branch is complete, robust, and verified.

All 250 targeted tests across 9 test suites passed with zero failures and zero leaks into the live .mam/jobs registry.

2. In-Depth Technical Verification

(1) Codex R1 & R2 Solutions (fae70c1)

• Codex R1 (AgyAgentAdapter.conversation_in_use):

  def _artifact_paths(self, uuid: str, ctx: DiscoveryContext) -> list:
      db = self.artifact_path(uuid, ctx)
      root = self._cli_root(ctx)
      return ([db] + [f"{db}{suffix}" for suffix in ("-wal", "-shm", "-journal")]
              + [f"{root}/brain/{uuid}", f"{root}/annotations/{uuid}.pbtxt",
                 f"{root}/presence/{uuid}.lock"])
  
  def conversation_in_use(self, uuid: str, ctx: DiscoveryContext) -> bool:
      return conversation_in_use(uuid, self._artifact_paths(uuid, ctx))
  

  conversation_in_use passes every associated file path to lsof -t. Even if a process holds open only presence/<uuid>.lock (or a -wal sidecar) via flock and carries neither the UUID in ps command-line arguments nor any session environment variable, lsof catches the active file descriptor and refuses the purge. Verified by tests/test_issue10_13_purge.py::test_purge_cli_refuses_when_only_the_presence_lock_is_held_open.

• Codex R2 (AgyAgentAdapter.has_artifacts & Orphan Resolution):

  def has_artifacts(self, uuid: str, ctx: DiscoveryContext) -> bool:
      return any(os.path.exists(p) for p in self._artifact_paths(uuid, ctx))
  

  If the main DB was previously unlinked or deleted, any remaining orphaned WAL files, annotations, or presence locks are recognized by has_artifacts. _resolve_purge_target correctly identifies agy as the owning agent and purges the stranded artifacts completely. Verified by tests/test_issue10_13_purge.py::test_purge_cli_resolves_agy_from_orphaned_leftovers.

• BaseAgentAdapter.has_artifacts Default Contract & Resolver Integration: In lib_py/agents/base.py:

  def has_artifacts(self, uuid: str, ctx: DiscoveryContext) -> bool:
      path = self.artifact_path(uuid, ctx)
      return uuid in path and os.path.exists(path)
  

  In lib_py/agents/__main__.py _resolve_purge_target:

  for name, adapter, ctx in probes:
      try:
          if adapter.has_artifacts(uuid, ctx):
              return name, adapter, ctx
      except Exception:
          continue
  

  • Shared Store Isolation: opencode uses a shared database path (opencode.db) which does not embed the UUID (uuid in path is False). Thus opencode never falsely claims other agents' UUIDs in the fallback pass.
  • Other Adapters (claude, hermes, grok, codex): All embed the UUID in their artifact paths (f".../{uuid}.jsonl", etc.). Their resolution behavior remains identical to the historical contract.

(2) Caller Session Protection (7610258) & Dynamic Fixtures (f5a6575)

• AGENT_SESSION_ENV Verification: Inspects CLAUDE_CODE_SESSION_ID, ANTIGRAVITY_CONVERSATION_ID, HERMES_SESSION_ID, GROK_SESSION_ID, and OPENCODE_SESSION_ID. If the caller's environment carries the target UUID, conversation_in_use immediately returns True.
• Helper-Chain Pruning (_is_agent_cli): Excludes the purge command's own non-agent helper processes (python interpreter, shell runners) but halts exclusion at the nearest agent CLI ancestor (claude, agy, hermes, grok, opencode, codex). If that agent CLI ancestor carries the UUID on its command line, it is treated as an active holder.
• Dynamic Test Fixtures (f5a6575): All purge tests in test_issue10_13_purge.py use dynamic uuid4 fixtures (conv and other), preventing false "in use" detections caused by concurrent delegation wrappers whose command-line prompts carry test file diffs.

(3) orc_onboard.sh Flow & Documentation Alignment

• Purge executes before registry mutation. A refused purge (exit code 5 due to in-use detection) leaves .mam/agent-sessions.yaml untouched.
• Confirmation gate (--yes) prevents accidental deletion (exit code 4).
• Missing on-disk artifacts emit a warning and cleanly remove the UUID registration (exit code 0).
• Past-tense grammatical correction maps add -> added, remove -> removed, eliminating the removeed typo.
• Full alignment with multi-agent-mux-orc-onboard/SKILL.md and VERSIONS.md v4.4.3.

(4) Registry & Audit Log Resolution (#15)

• default_registry_dir() and get_logs_dir() prioritize MAM_JOBS_DIR/DELEGATE_JOB_LOGS_DIR → $WORKSPACE_ROOT/.mam/... → <cwd>/.mam/....
• job_subscriber.py argument default updated to default_registry_dir().
• Verified zero test jobs leaked into .mam/jobs during test suite runs.

(5) Version Lockstep Completeness (v4.4.3)

• MAM_VERSION="4.4.3" in .agents/skills/lib.sh.
• FRAMEWORK_VERSION = "4.4.3" in .agents/skills/lib_py/loop/eager.py.
• 8 SKILL.md frontmatter versions: 4.4.3.
• VERSIONS.md: Current release v4.4.3, 8-row skills matrix 4.4.3, and changelog section updated to document codex R1/R2 and claude N1 refinements.
• Documentation badges in README.md, README.ko.md, BOOTSTRAP.md, BOOTSTRAP.ko.md, and MESSAGING.md header all synchronized.
• Verified no non-historical 4.4.2 references remain.

4. Conclusion

The refinements in fae70c1 thoroughly and elegantly address codex review findings R1 and R2 without introducing any regressions or architectural friction. All six review criteria are completely satisfied.

[VERDICT: PASS]
