+# Phase 03: Printer Configuration Verification Report
+
+**Phase Goal:** Printer configuration management — CRUD operations for printers, clients, detail/edit views
+**Verified:** 2026-04-10T12:30:00Z
+**Status:** human_needed — all automated checks pass; one Alpine.js behavior (PRNT-03) requires browser confirmation
+**Re-verification:** No — initial verification
+

+
+## Goal Achievement
+
+### Observable Truths
+
+| # | Truth | Status | Evidence |
+|----|-------|--------|----------|
+| 1 | User can fill in a printer form with name, IP, port, duplex, color, paper size, collate and save it | VERIFIED | `test_create_printer_persisted` passes; all 9 form fields present in `printer_form.html` and mapped in `POST /printers` handler |
+| 2 | Port name auto-populates from IP address (user can still edit it) | NEEDS HUMAN | `printer_form.html` contains correct Alpine.js `@input` handler and `portEdited` guard; runtime behavior untestable without a browser |
+| 3 | User can assign a printer to a client/tenant label | VERIFIED | `test_printer_grouped_by_client` passes; `client_id` FK wired in `create_printer`; client select in form template |
+| 4 | Saved printer appears in a grouped list after page refresh | VERIFIED | `test_create_printer_persisted` checks GET /printers; `test_printer_grouped_by_client` confirms `
` group headers rendered |
+| 5 | User can create a new client from the clients page | VERIFIED | `test_create_client` passes; `POST /clients` endpoint functional; `clients.html` contains HTMX form |
+| 6 | User can open a saved printer config and see all fields pre-populated | VERIFIED | `test_printer_detail_shows_driver` passes; `printer_detail.html` renders all 8 config fields |
+| 7 | User can see the associated driver info on the detail page | VERIFIED | `test_printer_detail_shows_driver` confirms driver name ("HP Universal") in response; `test_printer_detail_no_driver` confirms "No driver assigned" fallback |
+| 8 | A regenerate button is visible (disabled/placeholder until Phase 4) | VERIFIED | `printer_detail.html` line 28: `` |
+| 9 | User can delete a printer | VERIFIED | `test_delete_printer` passes; `DELETE /printers/{id}` endpoint functional; delete button with `hx-delete` in `printer_list.html` |
+| 10 | Full test suite passes with no regressions | VERIFIED | 61 tests pass across full suite |
+
+**Score:** 9/10 automated truths verified (Truth 2 pending human confirmation)

+## Required Artifacts
+
+| Artifact | Expected | Status | Details |
+|----------|----------|--------|---------|
+| `imptune/api/printers.py` | POST /printers with form parsing and validation; DELETE /printers/{id} | VERIFIED | 115 lines; all form fields, checkbox-to-bool conversion, FK resolution, error handling, `_render_printer_list` helper |
+| `imptune/api/clients.py` | POST /clients and GET (partial) endpoints | VERIFIED | 55 lines; duplicate-name IntegrityError handling, HTMX partial return |
+| `imptune/api/pages.py` | GET /printers, GET /clients, GET /printers/{id} page routes | VERIFIED | All three routes present with correct LEFT OUTER JOIN queries and template rendering |
+| `imptune/main.py` | Registers printers and clients routers | VERIFIED | Lines 34-35: `app.include_router(printers.router)` and `app.include_router(clients.router)` |
+| `imptune/templates/printers.html` | Printer list page grouped by client | VERIFIED | Extends base.html; includes printer_form.html and printer_list.html partials |
+| `imptune/templates/printer_detail.html` | Detail page with all fields, driver info, regenerate button | VERIFIED | Full-page template with 34 lines; all 7 config fields, conditional driver section, disabled regenerate button |
+| `imptune/templates/partials/printer_form.html` | Form with all 9 fields, Alpine.js port derivation | VERIFIED | All fields present: name, IP (x-model), port (x-model with portEdited guard), driver select, duplex, color checkbox, paper, collate checkbox, client select |
+| `imptune/templates/partials/printer_list.html` | Grouped printer list fragment for HTMX swap | VERIFIED | `
`; group by client in `
` headers; delete buttons with `hx-delete`; printer name links to detail |
+| `imptune/templates/clients.html` | Clients page with creation form | VERIFIED | Extends base.html; HTMX form targeting `#client-list`; includes client_list.html partial |
+| `imptune/templates/partials/client_list.html` | Client table partial | VERIFIED | `
`; table with name and created_at columns; empty state message |
+| `tests/test_printer_crud.py` | Integration tests for PRNT-01 through PRNT-10 | VERIFIED | 13 tests, all passing; covers all required behaviors including detail, 404, driver FK |
