I'll review each significant change in this diff.

### ftl_code_expert/cli.py:_reasons_export
VERDICT: CONCERN
CORRECTNESS: QUESTIONABLE
SPEC_COMPLIANCE: N/A
ISSUE_COMPLIANCE: N/A
BELIEF_COMPLIANCE: N/A
TEST_COVERAGE: UNTESTED
INTEGRATION: WIRED
REASONING: The removed line `network_path.write_text(result.stdout)` is a behavioral change. The comment claims `reasons export` writes `network.json` directly, but the sibling command `export-markdown` outputs to stdout and gets written via `beliefs_path.write_text(result.stdout)`. This asymmetry between the two export commands is not self-evident — if the assumption about `reasons export` writing the file directly is wrong, `network.json` will stop being updated. The `click.echo(f"Updated {network_path}")` still runs on success, which would be misleading if the file wasn't actually written. Should verify the actual behavior of `reasons export`.

### ftl_code_expert/cli.py:_verify_belief_with_observations
VERDICT: CONCERN
CORRECTNESS: QUESTIONABLE
SPEC_COMPLIANCE: N/A
ISSUE_COMPLIANCE: N/A
BELIEF_COMPLIANCE: N/A
TEST_COVERAGE: UNTESTED
INTEGRATION: WIRED
REASONING: The function logic is sound overall, but has a fragile pattern: comparing `seed_context != "(no initial source file)"` against a magic string to decide inclusion in `context_parts`. If the sentinel string ever changes in one place but not the other, it silently drops or includes wrong context. A boolean flag (`has_seed = True/False`) would be more robust. The lazy import of `read_file` inside the function body is fine but atypical for this codebase. No exception handling around the `invoke()` call for the observation prompt — if the LLM call fails, the exception propagates up to `_gather_verify_contexts` which catches it via `return_exceptions=True`, so the system won't crash, but the error message (`"Error gathering context for {bid}: {result}"`) will show a raw exception rather than a user-friendly message.

### ftl_code_expert/cli.py:_gather_verify_contexts
VERDICT: PASS
CORRECTNESS: VALID
SPEC_COMPLIANCE: N/A
ISSUE_COMPLIANCE: N/A
BELIEF_COMPLIANCE: N/A
TEST_COVERAGE: UNTESTED
INTEGRATION: WIRED
REASONING: Structurally mirrors `_gather_confirmation_context` with the addition of `model` and `timeout` parameters and slightly better error reporting (printing to stderr). The pattern is consistent with existing code. Errors are caught via `return_exceptions=True` on `asyncio.gather` and reported gracefully.

### ftl_code_expert/cli.py:verify
VERDICT: CONCERN
CORRECTNESS: VALID
SPEC_COMPLIANCE: N/A
ISSUE_COMPLIANCE: N/A
BELIEF_COMPLIANCE: N/A
TEST_COVERAGE: UNTESTED
INTEGRATION: WIRED
REASONING: Two notable changes: (1) Re-exporting via `_reasons_export()` before loading the network ensures fresh metadata — good defensive move but adds latency to every verify invocation. (2) The default behavior flips from simple file-read context to observation-based context (the new path requires an additional LLM call per belief for the observation prompt). This is a significant cost/latency increase for users who don't pass `--no-observe`. The flag naming `--no-observe` with `is_flag=True, default=False` means observations are ON by default — this is a breaking change in cost characteristics that should be noted in documentation or changelog. The integration between the flag and the two code paths is clean.

### ftl_code_expert/prompts/verify.py:VERIFY_OBSERVE_PROMPT
VERDICT: PASS
CORRECTNESS: VALID
SPEC_COMPLIANCE: N/A
ISSUE_COMPLIANCE: N/A
BELIEF_COMPLIANCE: N/A
TEST_COVERAGE: UNTESTED
INTEGRATION: WIRED
REASONING: Well-structured prompt. Clearly instructs the LLM to request observations without verifying the belief itself. The tool table and output format are consistent with the observation system used elsewhere. Guidelines asking for 3-8 targeted observations are reasonable. Format uses proper `{{` escaping for f-string compatibility.

### ftl_code_expert/prompts/__init__.py
VERDICT: PASS
CORRECTNESS: VALID
SPEC_COMPLIANCE: N/A
ISSUE_COMPLIANCE: N/A
BELIEF_COMPLIANCE: N/A
TEST_COVERAGE: UNTESTED
INTEGRATION: WIRED
REASONING: Clean addition of `VERIFY_OBSERVE_PROMPT` to imports and `__all__`. Alphabetical ordering maintained.

---

### SELF_REVIEW
LIMITATIONS: The "related test" observations were all false positives from sympy's vendored tests (matching on the word "verify" generically) — there appear to be no actual project tests for the verify command or the new observation functions, so I cannot assess whether existing tests break. I could not verify the actual behavior of `reasons export` (whether it writes to stdout or directly to file), which is critical to assessing the `_reasons_export()` change. I also couldn't see the full `_extract_source_file` or `_gather_belief_context` functions to compare patterns.

---

### FEATURE_REQUESTS
- Filter out test files from `.venv/` or other vendored directories when finding related tests — all 5 "related test" observations were false positives from sympy
- Include the actual project test files (e.g. `tests/test_cli.py`) if they exist, to verify coverage claims
- Show the implementation of functions called by new code (e.g. `_extract_source_file`, `parse_observation_requests`, `run_observations`) to verify correct usage of their APIs
