+# Task 3 Report
+
+Status: COMPLETE
+
+Runtime evidence/status:
+
+- Pre-import dependency/client gate: `UNKNOWN` unless provenance, client
+  version, client architecture, and Python/client architecture match are
+  proven before importing `fdb`.
+- Runtime compatibility fixture: `VALID` for `fdb 2.0.4`, client `2.5.9.27139`,
+  matching x64 architecture, and the exact read-only TPB.
+- `validate_firebird_runtime(fdb_module=None)`: `UNKNOWN` with
+  `compatibility_unproven`; read-only API proof is mandatory.
+- Success output exposes only compatibility categories/statuses and excludes
+  client paths, database identities, and internal provenance evidence.
+- Blocked output exposes only status, blocker, and safety counters; provenance
+  path fields are not serialized.
+
+Safety:
+
+- No database, external ERP file, DLL, service, registry, or system
+  configuration was accessed or modified.
+- `GIT_IDENTITY_NOT_CONFIGURED`.
+
+Tests:
+
+- `python -m pytest tests/test_dependency_compatibility.py -q`: 6 passed.
+- `python -m pytest tests -q`: 255 passed, 1 skipped.
