I have analyzed the logic in 'expert_build/pipeline.py' and 'expert_build/cli.py', and verified the test coverage in 'tests/test_pipeline.py'. I have identified some concerns regarding the loss of telemetry granularity and metadata in the 'cmd_pipeline' function due to the refactoring, but the core logic appears sound and well-tested.",title="Reviewing Derive-Review-Repair Implementation")

### expert_build/cli.py
VERDICT: PASS
CORRECTNESS: VALID
SPEC_COMPLIANCE: N/A
ISSUE_COMPLIANCE: N/A
BELIEF_COMPLIANCE: CONSISTENT
TEST_COVERAGE: COVERED
INTEGRATION: WIRED
REASONING: The new command `derive-review-repair` is correctly added to the CLI with appropriate arguments and is wired to the handler via lazy loading.
---

### expert_build/pipeline.py:_run_convergence_loop
VERDICT: PASS
CORRECTNESS: VALID
SPEC_COMPLIANCE: N/A
ISSUE_COMPLIANCE: N/A
BELIEF_COMPLIANCE: CONSISTENT
TEST_COVERAGE: COVERED
INTEGRATION: WIRED
REASONING: The logic from the pipeline's convergence loop was successfully extracted into a reusable function. It correctly handles stat accumulation, the optional callback, and the convergence condition (zero new derivations and zero invalid beliefs).
---

### expert_build/pipeline.py:cmd_derive_review_repair
VERDICT: PASS
CORRECTNESS: VALID
SPEC_COMPLIANCE: N/A
ISSUE_COMPLIANCE: N/A
BELIEF_COMPLIANCE: CONSISTENT
TEST_COVERAGE: COVERED
INTEGRATION: WIRED
REASONING: This new command implementation correctly uses the project's established patterns: it holds the system awake via `_caffeinate`, validates the model, ensures the database exists, and provides a clear summary of the convergence loop's results.
---

### expert_build/pipeline.py:cmd_pipeline
VERDICT: CONCERN
CORRECTNESS: VALID
SPEC_COMPLIANCE: N/A
ISSUE_COMPLIANCE: N/A
BELIEF_COMPLIANCE: CONSISTENT
TEST_COVERAGE: COVERED
INTEGRATION: WIRED
REASONING: While the logic remains correct, the refactoring introduced three regressions in observability and persistence:
1. **Telemetry Granularity**: Stages 4, 5, 6, and 7 are now marked as "completed" all at once at the end of the cycle (in `_pipeline_on_cycle`). Previously, each stage was marked immediately upon completion. This makes the `status` command less accurate and "resume" less efficient (it may redo a successful stage if a later stage in the same cycle fails).
2. **Metadata Loss**: Metadata for Stage 6 (linked, softened, abandoned counts) is no longer saved to the state file because the `on_cycle` callback does not receive the `repair_result` dict.
3. **UX regression**: The `_banner` calls for Stages 4-7 were removed, so the console output no longer provides clear visual separation for these stages during the pipeline run.

### tests/test_pipeline.py
VERDICT: PASS
CORRECTNESS: VALID
SPEC_COMPLIANCE: N/A
ISSUE_COMPLIANCE: N/A
BELIEF_COMPLIANCE: N/A
TEST_COVERAGE: COVERED
INTEGRATION: WIRED
REASONING: Comprehensive tests were added for both the new command and the refactored loop, covering convergence, max rounds, and edge cases like missing databases or unavailable models.
---

### SELF_REVIEW
LIMITATIONS: I was able to see the full body of the modified functions and the new tests, providing high confidence in the logic assessment. I did not see the `pipeline` command's original argument definitions in `cli.py` to verify if `--max-derive-rounds` was already present, but the existing code in `_stage_derive` relied on it, so I assume it was.
---

### FEATURE_REQUESTS
- It would be helpful to see the full content of `expert_build/cli.py` to verify that all command arguments are consistently defined across similar commands.
