VERDICT: PASS
CORRECTNESS: VALID
SPEC_COMPLIANCE: N/A
ISSUE_COMPLIANCE: ADDRESSES
BELIEF_COMPLIANCE: CONSISTENT
TEST_COVERAGE: COVERED
INTEGRATION: WIRED
REASONING: Correctly adds the `--resume` argument to the `pipeline` subcommand. The flag is properly integrated into the CLI parser and passed to the command handler.

### expert_build/pipeline.py
VERDICT: PASS
CORRECTNESS: VALID
SPEC_COMPLIANCE: N/A
ISSUE_COMPLIANCE: ADDRESSES
BELIEF_COMPLIANCE: CONSISTENT
TEST_COVERAGE: COVERED
INTEGRATION: WIRED
REASONING: Implements a clean and robust pipeline state management system. 
1. **State Persistence**: Correctly uses `PROJECT_DIR` (defined in `.propose` as `.expert-build`) for the state file, ensuring it resides within the project's working directory.
2. **Resume Logic**: Successfully implements stage-level granularity for Stages 1-3 and cycle-level granularity for the convergence loop (Stages 4-7). This is a pragmatic balance between complexity and efficiency.
3. **Error Handling**: The `try...except` block captures exceptions, records the error message and traceback in the state file, and re-raises the error, ensuring visibility into failures.
4. **Metadata**: The inclusion of `updated_at`, `current_cycle`, and stage-specific metadata (like `added` or `invalid` counts) provides excellent observability into the pipeline's progress.

### tests/test_pipeline.py
VERDICT: PASS
CORRECTNESS: VALID
SPEC_COMPLIANCE: N/A
ISSUE_COMPLIANCE: ADDRESSES
BELIEF_COMPLIANCE: CONSISTENT
TEST_COVERAGE: COVERED
INTEGRATION: WIRED
REASONING: New tests provide high-quality coverage for the resume feature.
- `test_state_file_created_on_run`: Verifies happy path state creation and final "completed" status.
- `test_state_records_failure`: Confirms that crashes record the error and traceback.
- `test_resume_skips_completed_stages`: Empirically verifies (via mocks) that completed stages are indeed skipped upon resume.
- `test_no_auto_accept_sets_paused`: Ensures the "paused" state is correctly recorded when manual intervention is required.

### SELF_REVIEW
LIMITATIONS: I cannot verify the idempotency of individual stage functions (e.g., `_stage_ingest`), but the pipeline-level skip logic correctly avoids re-executing them if they previously reached completion. I noted that `args.pdf` is not captured in the state metadata in `_init_state`, while `args.url` is; however, this is purely informational and does not affect the resumption logic as the current invocation's `args` are used during execution.
