Here's my review:

### ftl_code_expert/cli.py:verify (verified_at stamping block)
VERDICT: CONCERN
CORRECTNESS: QUESTIONABLE
SPEC_COMPLIANCE: N/A
ISSUE_COMPLIANCE: N/A
BELIEF_COMPLIANCE: N/A
TEST_COVERAGE: UNTESTED
INTEGRATION: WIRED
REASONING:

**1. Private API coupling.** `_with_network` is a private (underscore-prefixed) function in `reasons_lib.api`. This is the only usage from outside `reasons_lib` — every other call site is internal to the library. If `reasons_lib` refactors this function, this code silently breaks (caught by the `except`). Consider either promoting `_with_network` to a public API in `reasons_lib`, or adding a dedicated public function like `stamp_verified(db_path, node_ids, timestamp)`.

**2. Dual `verified_at` storage location.** The cli.py code sets `node.verified_at` (the dataclass field at `reasons_lib/__init__.py:45`), which is what `storage.py:138` persists. But `check_stale.py` sets `node.metadata["verified_at"]` (lines 119, 154, 350, 415, 463) — a different dict. Code that reads `metadata["verified_at"]` (e.g., staleness checks) won't see the value this code writes, and vice versa. Verify which location downstream consumers actually read; if both are read, one of the two write sites is wrong.

**3. `reasons_lib` is dev-only.** `ftl-reasons` is in `[dependency-groups] dev`, not in `[project] dependencies`. The `try/except` gracefully degrades, but users running a non-dev install get silent no-ops on every confirmed verification — no error, just no stamp. Consider either promoting it to an optional dependency with a clear user-facing message, or gating the import attempt on `_has_reasons()` to make the skip explicit.

**4. No tests.** The verify function has zero test coverage (observation confirms `test_count: 0`). The new stamping logic has multiple branches (confirmed non-empty, bid in net.nodes check, stamped count, exception path) that are all untested.

**5. Minor — hardcoded `"reasons.db"` path.** Consistent with the rest of the file, but the path is relative to CWD, not to the project directory. If the user runs the command from a subdirectory, this opens the wrong (or nonexistent) database. The existing retract block uses `_has_reasons()` as a guard; the stamp block doesn't.

### pyproject.toml
VERDICT: CONCERN
CORRECTNESS: VALID
SPEC_COMPLIANCE: N/A
ISSUE_COMPLIANCE: N/A
BELIEF_COMPLIANCE: N/A
TEST_COVERAGE: N/A
INTEGRATION: PARTIAL
REASONING:

The `[tool.uv.sources]` entry points to `../ftl-reasons`, a sibling directory. This only works when the contributor has this exact directory layout. CI environments and other contributors will fail to resolve this source. This is acceptable for local dev but should be documented or handled by CI config. The `ftl-reasons` package is also only a dev dependency, which means the runtime stamping feature added in `cli.py` has no formal dependency to back it — see the concern above.

---

### SELF_REVIEW
LIMITATIONS:
- Could not verify `check_stale.py`'s full staleness-check logic to confirm whether it reads `node.verified_at` or `node.metadata["verified_at"]` downstream — the dual-location concern may or may not be a real bug depending on which is authoritative.
- Could not see the full `Storage.save()` method to confirm which `verified_at` field it persists.
- No test files exist for the verify function, so I could not check for test breakage.
---

### FEATURE_REQUESTS
- Include the full `Storage.save()` and `Storage.load()` methods as observations when the diff touches persistence logic, to verify round-trip correctness.
- When a diff imports from a library, auto-observe the imported function's signature and docstring to catch private API usage and parameter mismatches.
