- Create imptune/api/icons.py with POST /printers/{printer_id}/icon
- Validate PNG format, 256x256 dimensions, 750KB max size
- Store icons SHA256-addressed under cfg.DATA_DIR/icons/
- Replace existing Icon record on re-upload
- Register icons.router in main.py with ICONS_DIR makedirs
- Patch cfg.ICONS_DIR in conftest.py for tests
- All 6 icon upload tests pass
- test_printer_detail_shows_driver: asserts driver name appears on detail page
- test_printer_detail_not_found: asserts 404 for missing printer ID
- test_printer_detail_no_driver: asserts graceful display when driver is None
- imptune/api/printers.py: POST /printers (all form fields, checkbox->bool,
FK resolution), DELETE /printers/{id}, grouped list renderer with LEFT JOIN
- imptune/api/clients.py: POST /clients with duplicate-name handling
- imptune/api/pages.py: GET /printers and GET /clients page routes
- imptune/main.py: register printers + clients routers; close db on shutdown
- imptune/db/database.py: close existing connection before re-init (test isolation)
- templates: printers.html, clients.html, printer_form.html (Alpine.js port
auto-derivation), printer_list.html (grouped by client), client_list.html
- tests/conftest.py: close test-thread db connection in fixture teardown
- tests/test_printer_crud.py: updated to use list(select().where()) for DB
queries (avoids Peewee thread-local cursor caching across test boundaries)
Auto-fix [Rule 1 - Bug]: DB test isolation — Peewee thread-local connections
persisted across tests causing stale DB reads; fixed via conftest teardown and
lifespan db.close() on shutdown.
- test_create_printer_persisted: POST /printers + GET /printers
- test_create_printer_duplex/color_mode/paper_size/collate: field persistence
- test_create_client: POST /clients + GET /clients
- test_printer_grouped_by_client: client group heading in list
- test_create_printer_missing_name/invalid_ip: validation 400s
- test_delete_printer: DELETE /printers/{id} removes record
- imptune/db/database.py: deferred SqliteDatabase with WAL + foreign_keys pragmas and init_db()
- imptune/db/models.py: full schema (Client, Driver, Printer, Icon) for phases 1-5
- imptune/storage/driver_store.py: SHA256 content-addressed DriverStore with dedup
- tests/test_db.py: 7 TDD tests covering all db and storage behaviors
- requirements-dev.txt with pytest and httpx
- tests/conftest.py: client and tmp_data_dir fixtures
- tests/test_health.py: GET /health returns 200 with {"status": "ok"}
- tests/test_static.py: no CDN URLs in templates, dashboard returns 200
- Fix imptune/api/pages.py: use request= kwarg in TemplateResponse (Starlette compat)
- Fix imptune/main.py: replace deprecated on_event with asynccontextmanager lifespan
- 14 tests covering outer ZIP structure, Detection.xml schema, key sizes
- Cryptographic roundtrip: HMAC-SHA256, AES-256-CBC decryption, file digest
- IV size assertion: must be 16 bytes (critical correction from RESEARCH.md)
- Tests serve as format specification for build_intunewin() implementation
