# 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 `<h3>` 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: `<button disabled aria-busy="false" title="Available after script generation is implemented (Phase 4)">Regenerate Package</button>` |
| 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)

## Requirements Coverage

| Requirement | Source Plan | Description | Status | Evidence |
|-------------|------------|-------------|--------|----------|
| PRNT-01 | 03-01 | User can set printer display name | SATISFIED | `name` field in form; `test_create_printer_persisted` verifies persistence |
| PRNT-02 | 03-01 | User can set printer IP address or hostname | SATISFIED | `ip_address` field in form; `test_create_printer_persisted` verifies |
| PRNT-03 | 03-01 | System auto-suggests port name from IP (user can override) | NEEDS HUMAN | Alpine.js logic present and correct in template; browser verification required |
| PRNT-04 | 03-01 | User can set duplex mode | SATISFIED | `duplex_mode` select with 3 options; `test_create_printer_duplex` verifies LongEdge |
| PRNT-05 | 03-01 | User can set color vs. grayscale default | SATISFIED | `color_mode` checkbox; `test_create_printer_color_mode` verifies False when unchecked |
| PRNT-06 | 03-01 | User can set paper size | SATISFIED | `paper_size` select with A4/Letter/Legal; `test_create_printer_paper_size` verifies |
| PRNT-07 | 03-01 | User can set collate on/off | SATISFIED | `collate` checkbox; `test_create_printer_collate` verifies False when unchecked |
| PRNT-08 | 03-01 | User can assign printer to a client/tenant label | SATISFIED | `client_id` FK select; `test_printer_grouped_by_client` verifies grouping |
| PRNT-09 | 03-01 | Printer configurations are persisted in SQLite across sessions | SATISFIED | `test_create_printer_persisted` verifies DB count and GET /printers shows saved record |
| PRNT-10 | 03-02 | User can regenerate a package from saved config without re-uploading drivers | SATISFIED (partial) | Detail page loads full config with driver FK intact (`test_printer_detail_shows_driver`); regenerate button present but disabled — full regeneration is a Phase 4 deliverable per plan scope |

## Anti-Patterns Found

None. Scanned `imptune/api/printers.py`, `imptune/api/clients.py`, `imptune/api/pages.py`, `imptune/templates/printers.html`, `imptune/templates/printer_detail.html` for TODO/FIXME/placeholder comments, empty return values, and console.log-only handlers. No issues found.

The disabled "Regenerate Package" button is intentional scope deferral (Phase 4), not a stub — documented in plan and REQUIREMENTS.md.

## Human Verification Required

### 1. Alpine.js Port Auto-Derivation (PRNT-03)

**Test:** Start the app (`uvicorn imptune.main:app --reload`). Navigate to `/printers`. In the printer form:
1. Type `192.168.1.100` into the IP Address field.
2. Verify that the Port Name field auto-fills to `IP_192_168_1_100` as you type.
3. Manually edit the Port Name field to `CUSTOM_PORT`.
4. Change the IP Address to `10.0.0.1`.
5. Verify the Port Name remains `CUSTOM_PORT` (not overwritten by the IP change).

**Expected:** Auto-fill works during step 2; manual edit lock works during step 5.

**Why human:** Alpine.js `@input` and `@change` handlers with `portEdited` flag execute in-browser JavaScript. The FastAPI `TestClient` does not run a JavaScript engine, so this behavior cannot be tested via pytest.

---

## Summary

Phase 03 goal is substantively achieved. All 10 requirement IDs (PRNT-01 through PRNT-10) are implemented with real code — no stubs, no placeholder routes, no empty handlers. The full test suite (61 tests) passes cleanly.

The only item requiring human confirmation is PRNT-03 (Alpine.js port auto-derivation from IP). The implementation is correct — the `x-data` block, `x-model` bindings, `@input` handler, and `portEdited` guard are all present in `printer_form.html` — but this is JavaScript behavior that only executes in a browser.

PRNT-10's "regenerate" button is disabled by design. The plan explicitly scopes Phase 3's PRNT-10 deliverable as "config retrievable with driver FK intact, regenerate button present as placeholder." The full regeneration workflow is Phase 4's responsibility. This is not a gap.
