1. Executive Summary & Verification Context

This is the Round 2 Delta Review of PR #38, evaluating the two commits (8a9101e and e80186f) added on top of ed293dc to resolve the review findings from Round 1:

1. N1/R1 (grok / codex, blocking): registry.get_feedback previously only parsed completed and error events, discarding cancelled event details. Sub-jobs cancelled prior to injection (e.g., target_not_found or session_busy) surfaced in the review table as bare uninformative cancelled rather than NOT-DISPATCHED.
2. R2 (codex, blocking): Remote runner deadlines publish error --detail "deadline_timeout (remote runner)". Exact-string matching in _subjob_state failed to identify this as an orchestrator timeout, missing CLOSED-UNCONFIRMED categorization and late-write warnings.
3. K1 (claude, non-blocking): The [귀속되지 않은 열린 잡] section displayed orphan jobs without explicit adjudication instructions.

Verification Identity & Git Cleanliness

• git rev-parse HEAD = e80186f56064eaf93a2f32c48d31d84816894774
• git rev-parse 'HEAD^{tree}' = 3501868872d828894f031911b8ca31b01ce77a72
• git diff ed293dc...HEAD --check = Clean (0 issues)
• git diff 7a4a0c2...HEAD --check = Clean (0 issues)
• Worktree Status: Clean

2. Detailed Verification of Round 1 Corrective Changes

(1) N1/R1 Fix: get_feedback Event Filtering & cancelled Detail Capture

• Files Modified:
  • lib_py/delegation/registry.py: get_feedback(job_id, registry_dir=..., events=("completed", "error"))
  • lib_py/loop/runner.py: _subjob_state() passes events=("completed", "error", "cancelled")
• Audit Findings:
  • Preserved Default Semantics: events parameter defaults to ("completed", "error"). Existing callers (such as registry.py CLI feedback / line 669) that pass only job_id and registry_dir remain 100% backward-compatible.
  • Dual-Path Support: Both the primary unified ndjson audit log path (e.get("source_event") in events / e.get("event") in events) and the fallback local .events.log path (payload.get("event") in events) correctly check against events.
  • Regression Test T13: Added test_t13_a_sub_job_cancelled_before_injection_is_not_dispatched_in_the_table parametrized over ["target_not_found", "session_busy"]. Both cases pass and confirm classification into | NOT-DISPATCHED | <reason> |. Without the fix, reason is empty and the table displays cancelled | -, failing the assertion.

(2) R2 Fix: Prefix Matching for Orchestrator Timeout Strings

• File Modified:
  • lib_py/loop/runner.py:

    closed_kind = reason.split(" ", 1)[0] if reason else ""
    if closed_kind in ORCHESTRATOR_CLOSED or (status == "error" and not reason):
        return "CLOSED-UNCONFIRMED", reason or "-"
    

• Audit Findings:
  • Accurate Prefix Extraction: reason.split(" ", 1)[0] extracts the initial keyword (e.g., "deadline_timeout" from "deadline_timeout (remote runner)").
  • No Misclassification: The candidate set ORCHESTRATOR_CLOSED strictly equals {"deadline_timeout", "agent_blocked"}. Other failure or cancellation reasons (such as session_busy, target_not_found, or rolled back...) have prefixes not in this set and therefore are never misclassified as CLOSED-UNCONFIRMED.
  • Regression Test T14: Added test_t14_the_remote_runners_deadline_wording_is_closed_unconfirmed using the real registry and event publisher. Verifies CLOSED-UNCONFIRMED state and 미확인 종결 1 warning in the prompt. Without closed_kind, this test fails.

(3) K1 Fix: STRAY_RULE Guidance for Unparented Open Jobs

• File Modified:
  • lib_py/loop/runner.py: Added STRAY_RULE constant and conditional injection into stray_line if and only if stray is non-empty.
• Audit Findings:
  • Rule Coherence: SUBJOB_RULE instructs reviewers to fail the round if any known sub-job is open, unconfirmed, or failed. STRAY_RULE instructs reviewers to fail the round if any unparented open job's deliverables were necessary for the task objectives. The two rules operate harmoniously and without contradiction.
  • Prompt Hygiene: When neither registered sub-jobs nor stray jobs exist, _subjobs_block() continues to return "", ensuring byte-for-byte prompt parity for non-delegating tasks.
  • Regression Test T6 Assertion: test_t6_an_unattributed_open_job_is_shown_and_waited_for_only_on_request now asserts that STRAY_RULE is included in the reviewer prompt.

3. Test Suite & Regression Verification

All tests were executed against the verification worktree (loop-20260925T072328Z-2f5853/1):

1. tests/test_issue34_job_tree.py:
   • 20 / 20 PASSED (including T13 parametrized × 2, T14, and updated T6) in 84.48s.
2. tests/test_version_consistency.py & tests/test_issue5_phase1_delegation.py:
   • 69 / 69 PASSED in 12.07s.
3. tests/test_issue23_24_startup_path.py & tests/test_loop_cli.py:
   • 79 / 79 PASSED in 195.92s.
4. Overall Total: 168 tests passed, 0 failures, 0 regressions.

4. Conclusion

All Round 1 reviewer findings (N1, R1, R2, K1) have been accurately addressed with clean, minimal code changes and rigorous regression test coverage. No edge-case misclassifications, prompt pollution, or regressions were detected. Version lockstep bump to v4.7.4 is properly reserved for the orchestrator release commit.

[VERDICT: PASS]
