VERDICT: PASS
CORRECTNESS: VALID
SPEC_COMPLIANCE: N/A
ISSUE_COMPLIANCE: N/A
BELIEF_COMPLIANCE: CONSISTENT
TEST_COVERAGE: COVERED
INTEGRATION: WIRED
REASONING: Adds the `--resume` flag to the `pipeline` subparser. This is a standard and correct way to extend the CLI to support the new functionality.

### expert_build/pipeline.py
VERDICT: PASS
CORRECTNESS: VALID
SPEC_COMPLIANCE: N/A
ISSUE_COMPLIANCE: N/A
BELIEF_COMPLIANCE: CONSISTENT
TEST_COVERAGE: COVERED
INTEGRATION: WIRED
REASONING: Implements a comprehensive state management system using a JSON file. The use of helper functions like `_mark_stage` and `_stage_completed` makes the pipeline logic clean and readable. 
- **Resumption Logic**: It correctly skips completed top-level stages (1-3) and tracks the iteration cycle for the convergence loop (4-7), ensuring that a resumed pipeline starts from the correct cycle. 
- **Error Handling**: The `try...except` block effectively captures and persists failure details (including tracebacks) into the state file, which is excellent for debugging long-running processes.
- **Pause Capability**: Integration with the `no_auto_accept` flag (Stage 3) allows the pipeline to gracefully "pause" and wait for manual user intervention before being resumed.
One minor observation is that stages 4-7 are not individually checked for completion within a cycle, meaning a resume will re-run all stages in the interrupted cycle. Given these stages involve database updates and LLM calls that should be relatively idempotent or handled by the "Deduplicate" stage, this is a safe and acceptable trade-off for implementation simplicity.

### tests/test_pipeline.py
VERDICT: PASS
CORRECTNESS: VALID
SPEC_COMPLIANCE: N/A
ISSUE_COMPLIANCE: N/A
BELIEF_COMPLIANCE: CONSISTENT
TEST_COVERAGE: COVERED
INTEGRATION: WIRED
REASONING: The added tests provide excellent coverage for the new feature.
- **Functional Verification**: Tests confirm that state files are created, updated on success/failure, and used to skip stages upon resumption.
- **Edge Cases**: Includes tests for missing state files, corrupted JSON data, and resuming already-completed pipelines.
- **Integration**: Correctly uses the `work_dir` fixture and mocks LLM calls to isolate the pipeline logic.

### SELF_REVIEW
LIMITATIONS: Review was conducted based on the provided diff and comprehensive observation results for key functions (`cmd_pipeline`, `_stage_extract`, `_stage_derive`, `_stage_review`). While I did not see the full implementation of `_stage_ingest` or `_stage_export`, their behavior is sufficiently exercised by the tests to verify the integration with the state management system.
