Scope: diff-only
HEAD checked: 6e65580228fc94039521ac3dcf73a9d2bbaf8b9a
What Improved
- Added structured
parallel_executor.dependency_graphlogging before execution starts, exposing inferred dependency edges that drive laterdependency_failedskips. - Added
parallel_executor.ac.verifier_rejectedlogging with the fat-harness rejection reason, typed-evidence status, verifier pass state, verifier reasons, and failure class. - Added regression coverage for both new diagnostic paths.
Issue #1164 Requirements
| Requirement | Status |
|---|---|
| Emit structured diagnostics when fat-harness/verifier rejects a runtime-successful AC. | MET — src/ouroboros/orchestrator/parallel_executor.py:5219 logs parallel_executor.ac.verifier_rejected with rejection reason and verifier details. |
| Make inferred dependency edges visible before dependency-failed cascades. | MET — src/ouroboros/orchestrator/parallel_executor.py:3328 builds and logs dependency edges at execution start. |
| Add regression coverage for the new diagnostics. | MET — tests cover verifier rejection logging at tests/unit/orchestrator/test_parallel_executor.py:5585 and dependency-edge logging at tests/unit/orchestrator/test_parallel_executor.py:6430. |

Test Coverage
Adequate. New dependency-edge logging at src/ouroboros/orchestrator/parallel_executor.py:3328 is covered by tests/unit/orchestrator/test_parallel_executor.py:6430. New verifier-rejection logging at src/ouroboros/orchestrator/parallel_executor.py:5219 is covered by tests/unit/orchestrator/test_parallel_executor.py:5585. All newly added logic/state-neutral diagnostics have corresponding tests.

Design / Roadmap Gate
Aligned. design_context.md frames this as an observability/diagnostic bug, not a semantics redesign. Current HEAD preserves the executor’s existing dependency and fat-harness acceptance behavior while adding traceability at the two requested points.
Merge Recommendation

New verifier-rejection logging at src/ouroboros/orchestrator/parallel_executor.py:5219 is covered by tests/unit/orchestrator/test_parallel_executor.py:5585.

Verified with PATH=/tmp/gitshim_1165:$PATH uv run pytest tests/unit/orchestrator/test_parallel_executor.py -q -> 190 passed, ruff check -> passed, and ruff format --check -> passed. Initial verification without the shim failed during package build because the local git wrapper timed out, not because tests failed.
Design / Roadmap Gate
Aligned. design_context.md:20-design_context.md:21 frames the bug as missing observability for verifier disagreement and dependency cascades, and design_context.md:56-design_context.md:59 asks for structured rejection logging plus visible dependency edges. Current HEAD preserves executor semantics while adding those diagnostics at src/ouroboros/orchestrator/parallel_executor.py:3328 and src/ouroboros/orchestrator/parallel_executor.py:5219.
Merge Recommendation

ouroboros-agent[bot]
Merge-readiness rationaleI re-reviewed this PR against the #961 AgentOS SSOT and the Track A / fat-harness direction. What this PR changes
Why this is aligned with the AgentOS direction
Over-engineering / direction check
Bot / roadmap evidence checked
Local verification
Conclusion: this PR is merge-ready. It improves diagnostic visibility for the #1164 failure mode while preserving the #961 AgentOS/fat-harness acceptance model. |
PR Review SummaryVerdictApprove Scope Reviewed
Blocking IssuesNone. WarningsNone. Mutation-Test Thinking
Complexity / CRAP-style Risk
Test Quality Assessment (6/7)
Security / Operational RiskNone. The PR does not touch auth, secrets, external command construction, persistence mutation, network behavior, or execution permissions. Operational risk is reduced because operators get explicit diagnostics for verifier rejection and dependency cascades. Looks Good
Final RecommendationApprove. This is a narrow, well-tested observability fix for #1164 and is consistent with the AgentOS SSOT direction in #961. It should be safe to merge once maintainers are ready. |

Design / Roadmap Gate
Affected-boundary review covered the executor state transition where runtime success is converted to AC failure, the typed-evidence/verifier persistence event emitted immediately afterward, checkpoint-resume placement before execution progress emission, and the dependency-plan consumer surface used to skip downstream ACs. The new logs are observational and do not alter replay state, persisted AC results, dependency scheduling, or verifier enforcement behavior.
Merge Recommendation
No current-HEAD blocker was found in the reviewed scope. Despite the required default verdict block, the implementation and tests are mergeable from this review pass.

- Added executor diagnostics for inferred dependency edges and fat-harness/verifier rejection details.

Issue #N/A Requirements
| Requirement | Status |
|---|---|
| Log inferred AC dependency edges at execution start | Implemented and covered by test_execute_parallel_logs_dependency_edges. |
| Log structured verifier/fat-harness rejection details before marking runtime-successful ACs failed | Implemented and covered by test_fat_harness_mode_rejects_verifier_fail. |
| Meaningful test coverage for newly added executor diagnostics | Satisfied for the executor diagnostic paths. |
| Keep release/plugin consumer metadata consistent with the build artifact | Failing: committed plugin/setup metadata says 0.39.1 while current HEAD builds as 0.24.1.dev1161. |

Blockers
| # | File:Line | Severity | Confidence | Finding |
|---|---|---|---|---|
| 1 | .claude-plugin/plugin.json:3 | High | 95% | The committed plugin metadata advertises 0.39.1, but current HEAD builds and installs as ouroboros-ai==0.24.1.dev1161, and uv run python scripts/sync-plugin-version.py reports drift for .claude-plugin/plugin.json, .claude-plugin/marketplace.json, and skills/setup/SKILL.md. This is a consumer-contract break because scripts/version-check.py:25 explicitly reads .claude-plugin/plugin.json before package metadata, so installed plugin users will see/report the wrong version and update checks can be suppressed or misdirected. The same stale 0.39.1 value is also present in .claude-plugin/marketplace.json:13 and skills/setup/SKILL.md:285. |

uv buildproducedouroboros_ai-0.24.1.dev1161, not the committed plugin metadata version.
Design / Roadmap Gate
Affected-boundary review covered executor state transitions, dependency blocking, replay/checkpoint restoration, typed evidence/verifier event emission, and consumer-facing plugin/version surfaces. The executor diagnostic changes appear additive and do not change the AC success/block/failure state machine on the tested paths. The merge gate fails at the plugin/release consumer boundary: version metadata shipped to Claude/plugin users is inconsistent with the package version and with the repository’s own sync script.
Merge Recommendation
Do not merge until .claude-plugin/plugin.json, .claude-plugin/marketplace.json, and skills/setup/SKILL.md are synchronized to the actual build version source, and the PR either narrows or explicitly accounts for the broad non-diagnostic scope currently present in HEAD.

Design / Roadmap Gate
Affected-boundary review covered the executor state machine around staged execution startup, dependency-derived skips, fat-harness acceptance enforcement, typed evidence emission, verifier verdict propagation, and structured logging serialization shape. The changes are diagnostics-only: they do not alter execution ordering, persistence/checkpoint recovery, replayed event payloads, AC outcome selection beyond the existing fat-harness path, or consumer-facing result contracts. No current-HEAD blocker found.
Merge Recommendation
Merge is reasonable. The PR is narrow, covered by focused tests, and local verification plus reported CI are passing.

Test Coverage Notes
- Reviewed added tests in
tests/unit/orchestrator/test_parallel_executor.pyfor verifier rejection logging and dependency-edge logging. - Attempted local test execution, but this container lacks
uv, andpython3 -m pytestcannot run becausepytestis not installed.
Design Notes
The PR is a narrow observability change in the existing executor path. It does not alter scheduling, dependency resolution, persistence, verifier acceptance, or retry semantics.
Design / Roadmap Gate
Affected boundaries are executor structured logging and fat-harness rejection telemetry. StagedExecutionPlan.get_dependencies() is total for missing indices, and VerifierVerdict already enforces valid rejection metadata, so the added log calls do not introduce a contract or persistence boundary failure.
Directional Notes
Maintainer memory emphasized avoiding duplicate execution paths and preserving contract boundaries. I focused on whether the new diagnostics drifted from runtime behavior; the changed code remains side-effect-only logging.
