@@ -80,6 +81,8 @@ Recent decisions affecting current work:
 - [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)
+- [Phase 03-02]: Detail page is a full-page template (not partial) — simpler than partial injection into printers.html
+- [Phase 03-02]: Route lives in pages.py (not printers.py) because it returns a full HTML page, not an HTMX fragment
