 - [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
+- [Phase 03-printer-configuration]: Use list(Model.select().where()) in tests instead of Model.get() — Peewee get() cursor caching fails across DB re-inits in same process
+- [Phase 03-printer-configuration]: Close test-thread DB connection in conftest.py teardown — thread-local Peewee connections persist across tests and read from stale DB
+- [Phase 03-printer-configuration]: Alpine.js portEdited guard prevents port overwrite after manual edit (PRNT-03)
