+# Phase 11 Plan 04: Client Name Navigation Summary
+
+One-liner: Per-client filtered printer page at GET /clients/{id} with clickable client names in printer group headers and client table, using grouped-dict reuse pattern from existing printer_list partial.
+
+## What Was Built
+
+- **GET /clients/{client_id} route** in `imptune/api/pages.py`: queries client by id (404 if not found), builds `grouped = {client.name: [printers]}` dict, passes full context (clients, driver_data) so printer_list partial with Edit/Delete modals works identically to /printers.
+- **client_detail.html template**: extends base.html, renders client name as `<h1>`, back-link to /clients, includes `partials/printer_list.html`.
+- **printer_list.html updated**: added `{% set group_client_id = printers[0].client_id if printers else None %}` + conditional `<h3>` — assigned clients get anchor link, Unassigned group remains plain text.
+- **client_list.html updated**: client name `<td>` now wraps name in `<a href="/clients/{{ c.id }}">`.
+
+## Tasks Completed
+
+| Task | Name | Commit | Files |
+|------|------|--------|-------|
+| 1 | GET /clients/{id} route + client_detail.html | f364479 | imptune/api/pages.py, imptune/templates/client_detail.html |
+| 2 | Client name links in printer_list.html and client_list.html | 5bf152b | imptune/templates/partials/printer_list.html, imptune/templates/partials/client_list.html |
+
+## Test Results
+
+All 3 UIE-03 scaffolded tests now GREEN:
+- `test_client_detail_returns_200` — PASSED
+- `test_client_detail_not_found` — PASSED
+- `test_client_links_in_printer_list` — PASSED
+
+Full non-E2E suite: **122/122 PASSED**
+
+E2E suite: 6/7 passed — `test_port_autofill[chromium]` FAILED (pre-existing failure, present before this plan's changes; deferred to deferred-items.md).
+
+## Decisions Made
+
+1. **client_id from printers[0].client_id**: Extracted in Jinja2 template rather than changing the grouped data structure. The `client_id` FK field on Printer returns raw integer when accessed as `.client_id`, avoiding FK object traversal. No changes to the route's grouped dict construction needed.
+2. **Unassigned group is plain text**: `group_client_id` evaluates to None/falsy for unassigned printers; `{% if group_client_id %}` condition cleanly handles both cases.
+3. **Route ordering**: `/clients/{client_id}` placed after `/clients` in pages.py to respect FastAPI path-specificity ordering — FastAPI matches literal `/clients` before the parameter route.
+
+## Deviations from Plan
+
+None — plan executed exactly as written. All recommended approaches in the plan's interfaces section worked as described without modification.
+
+## Out-of-Scope Items Deferred
+
+`test_port_autofill[chromium]` E2E failure: pre-existing, introduced when Plan 11-01 separated the add-printer form to `/printers/new` while the test still navigates to `/printers` expecting `input[name='ip_address']`. Logged in `.planning/phases/11-ui-enhancements/deferred-items.md`.

+## Deferred Items — Phase 11 UI Enhancements
+
+### test_port_autofill[chromium] E2E failure (out of scope for 11-04)
+
+**Discovered during:** Plan 11-04 final verification
+**Status:** Pre-existing failure — verified present on commit 7b948b6 (before 11-04 changes)
+**Root cause:** `tests/e2e/test_port_autofill.py` navigates to `/printers` and waits for `input[name='ip_address']`. Plan 11-01 separated the add-printer form to `/printers/new`, so the input no longer exists on `/printers`.
+**Fix needed:** Update `test_port_autofill` to navigate to `/printers/new` instead of `/printers`.
+**Files:** `tests/e2e/test_port_autofill.py`
