@@ -71,6 +72,10 @@ Recent decisions affecting current work:
 - [Phase 01-foundation]: init_db() added to lifespan (not @app.on_event) consistent with 01-01 established pattern
 - [Phase 02]: optionxform=str on RawConfigParser preserves DriverDesc key casing; strings dict uses lowercase keys for case-insensitive token lookup
 - [Phase 02]: RawConfigParser(strict=False) required for real INFs that have duplicate option keys within sections
+- [Phase 02-driver-management]: Always render <select> even for single-model drivers — uniform UI and simpler template logic
+- [Phase 02-driver-management]: Dynamic DRIVERS_DIR read (import config module not constant) so monkeypatch works in integration tests
+- [Phase 02-driver-management]: TestClient must use context manager for Starlette 0.46+ lifespan trigger (init_db)
+- [Phase 02-driver-management]: HTMX errors: return HTMLResponse with driver-list div wrapper so HTMX outerHTML swap works for error states
