### expert_build/llm.py:extract_json
VERDICT: PASS
CORRECTNESS: VALID
SPEC_COMPLIANCE: N/A
ISSUE_COMPLIANCE: N/A
BELIEF_COMPLIANCE: CONSISTENT
TEST_COVERAGE: COVERED
INTEGRATION: WIRED
REASONING: The function correctly centralizes JSON extraction logic. It handles both objects and arrays, successfully strips Markdown code fences if present, and robustly finds JSON structures embedded within conversational text by scanning for the first brace/bracket and last brace/bracket. The logic includes a fallback mechanism if the first identified structure (array or object) fails to parse.

### expert_build/coverage.py:cmd_cert_coverage
VERDICT: PASS
CORRECTNESS: VALID
SPEC_COMPLIANCE: N/A
ISSUE_COMPLIANCE: N/A
BELIEF_COMPLIANCE: CONSISTENT
TEST_COVERAGE: COVERED
INTEGRATION: WIRED
REASONING: The function now utilizes structured JSON matching, which is more reliable than the previous line-based parsing. It includes a retry mechanism for malformed LLM responses and correctly validates extracted belief IDs against the known inventory before adding them to matches.

### expert_build/propose.py:cmd_propose_beliefs
VERDICT: PASS
CORRECTNESS: VALID
SPEC_COMPLIANCE: N/A
ISSUE_COMPLIANCE: N/A
BELIEF_COMPLIANCE: CONSISTENT
TEST_COVERAGE: COVERED
INTEGRATION: WIRED
REASONING: Successfully transitioned from fragile regex/line-based parsing of belief proposals to structured JSON parsing. The implementation maintains the existing human-readable Markdown output format while benefiting from the reliability of structured data during the extraction and deduplication phases.

### expert_build/exam.py
VERDICT: PASS
CORRECTNESS: VALID
SPEC_COMPLIANCE: N/A
ISSUE_COMPLIANCE: N/A
BELIEF_COMPLIANCE: CONSISTENT
TEST_COVERAGE: COVERED
INTEGRATION: WIRED
REASONING: Callers of the former `_extract_json` (now `extract_json` in `llm.py`) have been correctly updated. Redundant code and constants have been removed, improving maintainability.

### expert_build/prompts.py
VERDICT: PASS
CORRECTNESS: VALID
SPEC_COMPLIANCE: N/A
ISSUE_COMPLIANCE: N/A
BELIEF_COMPLIANCE: CONSISTENT
TEST_COVERAGE: COVERED
INTEGRATION: WIRED
REASONING: The `PROPOSE_BELIEFS` and `CERT_MATCH` prompts have been appropriately updated to request structured JSON output, aligning with the new parsing logic in the implementation files.

### tests/test_coverage.py
VERDICT: PASS
CORRECTNESS: VALID
SPEC_COMPLIANCE: N/A
ISSUE_COMPLIANCE: N/A
BELIEF_COMPLIANCE: CONSISTENT
TEST_COVERAGE: COVERED
INTEGRATION: WIRED
REASONING: This is a high-quality new test suite that comprehensively covers the certification coverage logic. It explicitly tests successful JSON parsing, retry logic for bad responses, code fence handling, and empty result sets, ensuring the feature is robust.

### SELF_REVIEW
LIMITATIONS: I have reviewed the full function bodies for all modified logic and the new test file. Integration is verified across all major commands (`coverage`, `propose`, `exam`).
