+# Phase 11 Plan 02: Printer Edit Modal (UIE-01) Summary
+
+**One-liner:** HTMX PATCH route + Pico CSS native dialog edit modal with Alpine.js port guard and Playwright E2E coverage.
+
+## What Was Built
+
+UIE-01 is now complete: every printer row in the library has an Edit button that opens a pre-filled native `<dialog>` modal. Submitting the form sends a HTMX PATCH to `/printers/{id}`, closes the modal, and refreshes the printer list in-place without a page reload.
+
+### Key Changes
+
+- **`imptune/api/printers.py`** — Added `PATCH /{printer_id}` route handler with full validation (name/ip/port required, duplex/paper enum checks). Optional `ip_address` and `port_name` fall back to existing values when not submitted. Updated `_render_printer_list` to pass `clients` and `driver_data` in the template context for modal pre-population. Imported `Driver` at module level.
+
+- **`imptune/templates/partials/printer_edit_modal.html`** (new, 98 lines) — Pico CSS native `<dialog>` with Edit trigger button and HTMX PATCH form. Uses `hx-on::after-request` to close the modal on success. Alpine.js `x-data` sets `portEdited: true` so editing IP does not overwrite a manually-set port. Pre-fills all printer fields including driver/client selects with `selected` conditional.
+
+- **`imptune/templates/partials/printer_list.html`** — Actions `<td>` updated: `{% include "partials/printer_edit_modal.html" %}` inserted before the Delete button, inside the `{% for p in printers %}` loop so `p` is in scope.
+
+- **`tests/e2e/test_printer_edit.py`** (new) — Two Playwright E2E tests: modal open and pre-fill verification; submit updates list via HTMX PATCH. Row targeting uses `page.locator("tr", has=page.locator("a", has_text="OriginalName"))` to handle session-scoped live_server accumulating data across tests.
+
+## Test Results
+
+| Suite | Status |
+|-------|--------|
+| test_patch_printer | GREEN |
+| test_patch_printer_not_found | GREEN |
+| test_printer_edit_modal_open_and_prefill | GREEN (E2E) |
+| test_printer_edit_submit_updates_list | GREEN (E2E) |
+| Full non-E2E suite | 120 passed, 2 expected RED (UIE-03 Wave 0) |
+
+## Commits
+
+| Hash | Message |
+|------|---------|
+| `4b212b6` | feat(11-02): PATCH /printers/{id} route handler and updated _render_printer_list |
+| `7b948b6` | feat(11-02): UIE-01 edit modal — Edit button per row, Pico dialog, E2E tests |
+
+## Deviations from Plan
+
+### Auto-fixed Issues
+
+**1. [Rule 2 - Missing functionality] ip_address and port_name made optional in PATCH handler**
+- **Found during:** Task 1 — reviewing Wave 0 test scaffold `test_patch_printer`
+- **Issue:** The plan specified `ip_address: str = Form(...)` and `port_name: str = Form(...)` as required, but the existing RED scaffold test only sends `{"name": "Updated Name"}`. The handler would have returned 422 Unprocessable Entity.
+- **Fix:** Changed `ip_address` and `port_name` to `Form("")` with fallback to `printer.ip_address` / `printer.port_name` when empty, preserving validation logic while passing the test.
+- **Files modified:** `imptune/api/printers.py`
+- **Commit:** `4b212b6`
+
+**2. [Rule 1 - Bug] E2E test_printer_edit_submit_updates_list used wrong selector for session-scope isolation**
+- **Found during:** Task 2 — E2E test run
+- **Issue:** `page.click("button:has-text('Edit')")` clicked the first Edit button in the list, which belonged to a printer from a previous test (session-scoped live_server). The targeted printer ("OriginalName") was not updated.
+- **Fix:** Changed to `page.locator("tr", has=page.locator("a", has_text="OriginalName")).locator("button:has-text('Edit')").click()` to target the specific row. Also updated assertion to check anchor text (`a:has-text`) rather than `td:first-child` inner text, and used `page.wait_for_selector("a:has-text('UpdatedName')")` for HTMX swap completion.
+- **Files modified:** `tests/e2e/test_printer_edit.py`
+- **Commit:** `7b948b6`
+
+## Success Criteria Check
+
+- [x] Every printer row has an Edit button
+- [x] Clicking Edit opens a native dialog pre-filled with that printer's current data
+- [x] Submitting the edit form sends HTMX PATCH, closes the modal, and updates the list
+- [x] PATCH /printers/{id} validated via test_patch_printer (GREEN)
+- [x] PATCH /printers/9999 returns 404 (confirmed by test_patch_printer_not_found)
+- [x] E2E tests pass: modal opens, name is pre-filled, submit updates list

+
+**Alpine.js stores for Light/Dark/System theme cycling and FR/EN i18n toggle in base.html, both persisted via localStorage, with 4 passing Playwright E2E tests**
+
+## Performance
+
+- **Duration:** 4 min
+- **Started:** 2026-04-15T09:05:49Z
+- **Completed:** 2026-04-15T09:10:08Z
+- **Tasks:** 2
+- **Files modified:** 4 (base.html, app.css, test_static.py, + 2 created E2E test files)
+
+## Accomplishments
+- Alpine.store('theme') registered via alpine:init with Light/Dark/System cycling, localStorage persistence, and :aria-label binding for state tracking
+- Alpine.store('i18n') with complete FR/EN translation dictionary covering all static UI strings (30+ keys per language)
+- Top-right topbar added to base.html layout with theme toggle and lang toggle buttons, styled via new .main-wrapper + .topbar CSS classes
+- 4 E2E Playwright tests: theme cycles, theme persists, lang switches nav label, lang persists — all GREEN
+
+## Task Commits
+
+Each task was committed atomically:
+
+1. **Task 1: Alpine.js stores + top-right controls in base.html** - `3353f45` (feat)
+2. **Task 2: E2E tests for theme toggle and language toggle** - `4db15d6` (test)
+
+## Files Created/Modified
+- `imptune/templates/base.html` - Alpine.js stores script (alpine:init), topbar with toggle buttons, x-text nav bindings
+- `imptune/static/app.css` - Added .main-wrapper, .topbar, .topbar-controls styles
+- `tests/test_static.py` - Added test_theme_toggle_present; fixed test_dashboard_shows_recent_printers assertion
+- `tests/e2e/test_theme_toggle.py` - 2 E2E tests: theme cycles on click, theme persists across reload
+- `tests/e2e/test_i18n_toggle.py` - 2 E2E tests: lang toggle switches nav label, lang persists across reload
+
+## Decisions Made
+- Alpine stores registered via alpine:init event before the defer alpine.min.js script — inline scripts run synchronously before any deferred scripts, guaranteeing stores are defined before Alpine initializes
+- x-data placed on the .topbar-controls div wrapper instead of individual buttons — scopes Alpine once for both controls
+- :aria-label bound to $store.theme.current — provides a reactive state indicator that doubles as a stable Playwright selector (button[aria-label='auto'], button[aria-label='light'], etc.)
+- Test assertion in test_dashboard_shows_recent_printers updated: raw string "No printers configured yet" now appears in the inline i18n JS, so assertion narrowed to class-qualified check
+
+## Deviations from Plan
+
+### Auto-fixed Issues
+
+**1. [Rule 1 - Bug] Fixed test_dashboard_shows_recent_printers false failure due to i18n string**
+- **Found during:** Task 1 (base.html stores + controls)
+- **Issue:** Adding the i18n translation dictionary inline in base.html embeds the string `'No printers configured yet.'` verbatim in the JS. The existing test asserted this string was absent from the response, which now always fails regardless of DB state.
+- **Fix:** Narrowed assertion to `'class="empty-state">No printers configured yet'` — this checks for the server-rendered HTML element rather than the raw string, which correctly distinguishes actual empty-state rendering from JS dictionary content.
+- **Files modified:** tests/test_static.py
+- **Verification:** test_dashboard_shows_recent_printers passes; all 6 test_static.py tests GREEN
+- **Committed in:** 3353f45 (Task 1 commit)
+
+---
+
+**Total deviations:** 1 auto-fixed (Rule 1 - bug in test assertion caused by i18n strings in HTML)
+**Impact on plan:** Necessary correctness fix. No scope creep.
+
+## Issues Encountered
+- Two pre-existing failures in tests/test_printer_crud.py (test_client_detail_returns_200, test_client_links_in_printer_list) confirmed pre-existing by git stash check — out of scope, logged for deferred triage.
+
+## User Setup Required
+None - no external service configuration required.
+
+## Next Phase Readiness
+- UIE-04 (theme toggle) and UIE-05 (i18n FR/EN) complete and verified
+- base.html now has Alpine.js stores available globally — future plans can use $store.i18n.t() for any new static UI strings
+- To add new translation keys: extend translations.fr and translations.en objects in the inline script in base.html

+## Requirements Traceability Note
+
+UIE-01 through UIE-05 are defined in ROADMAP.md (Phase 11 section) and in the PLAN frontmatter for plans 11-01 through 11-04. They are **not** present in `.planning/REQUIREMENTS.md`, which covers only v1.1 Hardening requirements (RTVAL, UX, NYQ, RWR). The UIE IDs form a separate requirements namespace declared at phase definition time. No orphaned requirements were found — all five UIE IDs are claimed by plans within this phase.

+## Human Verification Required
+
+### 1. Add Printer Page Visual Separation (UIE-02)
+
+**Test:** Open `/printers/new` in a browser and observe the page layout.
+**Expected:** The Add Printer form occupies a clean standalone page; the link from `/printers` to `/printers/new` is prominent enough that a technician would not miss it.
+**Why human:** Visual discoverability and layout quality cannot be asserted by tests.
+
+### 2. Full Language Switch Coverage (UIE-05)
+
+**Test:** Toggle FR→EN and EN→FR on any page; visually scan all text including nav items, buttons (Edit, Delete, Save, Cancel), headings, and empty-state messages.
+**Expected:** All static UI strings switch with no stale hardcoded English or French text remaining after the toggle.
+**Why human:** E2E tests verify only the nav "Printers" label. The 30-key translation dictionary coverage across all pages requires a full-page visual scan.
+
+### 3. Edit Modal Full Pre-Fill (UIE-01)

+**Test:** Click the Edit button on a printer that has a driver assigned, a client assigned, and non-default duplex/paper settings.
+**Expected:** All fields (name, IP, port, driver dropdown, duplex select, color checkbox, paper select, collate checkbox, client dropdown) are pre-filled with that printer's current values.
+**Why human:** Integration and E2E tests verify name pre-fill and submit; verifying that every dropdown `selected` attribute correctly reflects saved values requires visual inspection.

+## Gap Summary
+
+No gaps. All five UIE requirements are satisfied by verified, wired, substantive artifacts. The full 122-test non-E2E suite passes with no regressions. All six Phase 11 E2E tests pass. The single E2E failure (`test_port_autofill[chromium]`) is pre-existing and out of scope — it predates Phase 11-01 changes and is tracked in `deferred-items.md`.
