+# TDD Evidence: speckit-02-v04-adapter-alignment
+
+## Implementation Order
+
+Production code for tasks 1.1–7.2 was written first (ToolCapabilities fields, scanner methods, version detection, bridge presets, get_capabilities integration). Tests were then written targeting all new behavior.
+
+## Post-Implementation Test Run (passing)
+
+**Timestamp:** 2026-03-27T23:13:50Z
+
+**Command:** `hatch test -- tests/unit/models/test_capabilities.py tests/unit/models/test_bridge.py tests/unit/importers/test_speckit_scanner.py tests/unit/adapters/test_speckit.py -v`
+
+**Result:** 110 passed in 4.90s
+
+New tests added:
+- `TestToolCapabilitiesV04Fields` — 8 tests (backward compat, all new fields)
+- `TestScanExtensions` — 7 tests (catalog parsing, ignore, malformed JSON, merge)
+- `TestScanPresets` — 4 tests (JSON, directory, malformed fallback)
+- `TestScanHookEvents` — 4 tests (pattern detection, sorting, edge cases)
+- `TestVersionDetection` — 8 tests (heuristics, CLI mock, priority)
+- `TestGetCapabilitiesV04` — 7 tests (extensions, presets, hooks, version, cross-repo, legacy)
+- `TestBridgeConfigPresets` — 4 new parametrized tests (7-command set validation)
+
+## Full Suite Run (passing)
+
+**Timestamp:** 2026-03-27T23:13:50Z
+
+**Command:** `hatch test --cover -v`
+
+**Result:** 2248 passed, 9 skipped in 171.02s
+
+## Quality Gates

+| `hatch run format` | All checks passed | 2026-03-27T23:12Z |

+
+## Note
+
+Production code was written before tests in this change (not strict TDD red-green-refactor). The OpenSpec change was created with specs and design first, followed by implementation and then test coverage. All new public methods have `@beartype` and `@icontract` contracts as primary validation, with unit tests as secondary coverage per project conventions.
