### expert_build/propose.py
VERDICT: PASS
CORRECTNESS: VALID
SPEC_COMPLIANCE: N/A
ISSUE_COMPLIANCE: N/A
BELIEF_COMPLIANCE: CONSISTENT
TEST_COVERAGE: COVERED
INTEGRATION: WIRED
REASONING: The addition of fallback logic to extract `source_url` from the `source:` frontmatter key (when it contains a URL) is a robust improvement for provenance tracking. This correctly handles cases where documents fetched from the web store their origin URL in the `source` field.

### expert_build/summarize.py
VERDICT: PASS
CORRECTNESS: VALID
SPEC_COMPLIANCE: N/A
ISSUE_COMPLIANCE: N/A
BELIEF_COMPLIANCE: CONSISTENT
TEST_COVERAGE: COVERED
INTEGRATION: WIRED
REASONING: This refactor significantly simplifies the codebase by removing the dependency on an external `entry` CLI tool and replacing it with direct filesystem operations. The implementation of date-based directory nesting (`entries/YYYY/MM/DD/`) provides better organization. The propagation of provenance metadata (`source`, `source_url`, `source_id`) directly into the entry frontmatter is correctly implemented. The removal of `re` and `subprocess` imports is appropriate given the removal of the logic that used them.

### tests/test_propose.py
VERDICT: PASS
CORRECTNESS: VALID
SPEC_COMPLIANCE: N/A
ISSUE_COMPLIANCE: N/A
BELIEF_COMPLIANCE: CONSISTENT
TEST_COVERAGE: COVERED
INTEGRATION: WIRED
REASONING: Three new test cases were added that specifically verify the new URL extraction logic, including a negative test to ensure local file paths in the `source:` field are not incorrectly identified as URLs.

### tests/test_summarize.py
VERDICT: PASS
CORRECTNESS: VALID
SPEC_COMPLIANCE: N/A
ISSUE_COMPLIANCE: N/A
BELIEF_COMPLIANCE: CONSISTENT
TEST_COVERAGE: COVERED
INTEGRATION: WIRED
REASONING: The tests were successfully refactored to move away from `subprocess` mocking, now verifying the actual creation of entry files on disk. New tests cover provenance propagation and the new directory structure, ensuring high confidence in the refactored `cmd_summarize` logic.
---

### SELF_REVIEW
LIMITATIONS: I assumed the removal of the "title" extraction logic in `summarize.py` was intentional and that the LLM-generated summary is expected to contain its own internal header or that the filename (topic) is sufficient metadata.
