# 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.
