+# Phase 9 Plan 03: Script Download Links Summary
+
+**Three .ps1 route aliases (install/uninstall/detect) + Scripts section on printer detail page, closing UX-03 with direct individual script downloads**
+
+## Performance
+
+- **Duration:** 18 min
+- **Started:** 2026-04-13T08:46:27Z
+- **Completed:** 2026-04-13T09:04:00Z
+- **Tasks:** 2 (TDD: RED then GREEN)
+- **Files modified:** 4
+
+## Accomplishments
+
+- Added `.ps1`-suffixed route aliases for all three script endpoints via shared `_*_response()` helpers
+- Added Scripts section to `printer_detail.html` inside the `{% if has_driver %}` guard with 3 direct download anchor links
+- 6 new tests: 5 in `test_script_download.py` covering all .ps1 routes (200, 404, 422), 1 in `test_packages.py::TestCommandPreview` for template link presence
+- Full non-e2e suite: 106/106 passing with no regressions
+
+## Task Commits
+
+Each task was committed atomically:
+
+1. **Task 1: Wave 0 — failing tests for .ps1 routes + detail page script links** - `d359001` (test)
+2. **Task 2: Add .ps1 route aliases + printer_detail.html script links** - `68a2935` (feat)
+
+**Plan metadata:** (docs commit to follow)
+
+_Note: TDD tasks have two commits (test RED → feat GREEN)_
+
+## Files Created/Modified
+
+- `tests/test_script_download.py` - 5 integration tests for the 3 new .ps1 routes (install/uninstall/detect, 404, 422)
+- `tests/test_packages.py` - Added `test_detail_page_shows_script_links` to `TestCommandPreview`
+- `imptune/api/scripts.py` - Refactored to shared helpers, added 3 `.ps1` route aliases
+- `imptune/templates/printer_detail.html` - Added Scripts section with 3 download links before Export section
+
+## Decisions Made
+
+- `.ps1` routes implemented as aliases (not renames) to preserve backward compatibility — existing extensionless routes remain functional
+- Scripts section inserted inside existing `{% if has_driver %}` guard per plan spec (no scripts without a driver)
+- Shared `_install_response()`, `_uninstall_response()`, `_detect_response()` helpers avoid logic duplication between the two URL shapes
+
+## Deviations from Plan
+
+None — plan executed exactly as written.
+
+## Issues Encountered
+
+During a `git stash` probe to check a pre-existing test failure, a stash from a previous 09-01 session was inadvertently popped into `tests/test_driver_upload.py`. The file was restored to its committed state via `git checkout --` before committing. The pre-existing test failure (`test_upload_returns_oob_when_called_from_form`) is out-of-scope for 09-03 and belongs to the 09-01 plan scope.
+
+## User Setup Required
+
+None — no external service configuration required.
+
+## Next Phase Readiness
+
+- UX-03 closed: technician can download each script individually from the printer detail page
+- Existing package export buttons untouched
+- Ready for Phase 10 real-world runtime validation
