   `copy_from_cache_to_temp` + `run_osascript` / `run_cmd` directly instead of the all-in-one
   `launch_from_cache`. Finer error handling at each step (verify copy succeeded before
   attempting script; surface failure clearly in UI).
-- [ ] **[Launcher] Error handling + fallback** — when the launch script fails, offer fallback
-  to `open_local_file_v2` (OS default handler) rather than silently failing. Show error detail
-  in the launcher file row so staff can diagnose onsite.
+- [x] **[Launcher] Error handling + fallback (2026-05-14)** — post-script failure is non-fatal: surfaces `'fallback'` status with error detail (file already open). If `open_cmd` itself fails, falls back to `open_local_file_v2` (OS default); surfaces combined error detail if that also fails. UI renders `'open'` / `'fallback'` / `'error'` states distinctly.
 - [ ] **[Launcher] Slide control scripts in Svelte config** — `control_presentation` AppleScript
-  one-liners are hardcoded in Electron. Move to device config (`data_json.control_scripts`) or
-  Svelte constants so slide nav behavior (e.g. keystroke vs. AppleScript command) can be adjusted
-  without a rebuild. Wire through `run_osascript` directly.
-- [ ] **[Launcher] `kill_processes` target list in config** — process names to kill on cleanup
-  are currently caller-hardcoded. Allow device config to specify the process name list per
-  file type / app, so adding a new presentation app doesn't require a Svelte code change.
-- [ ] **[Launcher] Launcher config UI — launch_profiles editor** — add a Technical Mode panel
-  in the Launcher config (tabbed settings) to view and edit `launch_profiles` entries on the
-  active device record. PATCH via `event_device` V3 CRUD. Lets OSIT staff tune launch behavior onsite
-  without needing phpMyAdmin or a code deploy.
+  one-liners are hardcoded in Electron (`shell_handlers.ts` lines 149–159). The Svelte side
+  (`launcher_cfg_native_os.svelte`) already calls `native.control_presentation({ app, action })`
+  with next/prev/start/stop buttons wired and working. The Electron IPC call is stable enough
+  for current shows.
+
+  **Remaining (post June 10):** Move scripts to device config (`data_json.control_scripts`) or
+  Svelte constants so behavior can be changed without an Electron rebuild. Replace
+  `native.control_presentation()` call with `native.run_osascript(script)` using the
+  config-resolved script string. The `run_osascript` primitive is already in place; this is
+  purely a wiring/config task. Low priority — hardcoded scripts work fine for PowerPoint and
+  Keynote for now.
+- [ ] **[Launcher] `kill_processes` target list in config** — The `kill_processes` IPC primitive
+  exists in Electron and is exposed via `electron_relay.ts`, but **is never called from anywhere
+  in Svelte** — no routes, no config components, no file launch flow. No UI exists for it yet.
+
+  **What needs doing (post June 10):**
+  - Decide where the "kill on cleanup" action lives: end of `handle_open_file()` (auto), or a
+    manual "Kill Apps" button in Native OS config, or both.
+  - Process names should come from device config (`data_json.kill_process_li`) with a built-in
+    fallback list (e.g. `['Microsoft PowerPoint', 'Keynote', 'LibreOffice Impress']`).
+  - The Native OS config section (`launcher_cfg_native_os.svelte`) is the natural home for a
+    manual kill button; auto-cleanup on file open would go in `launcher_file_cont.svelte`.
+
+  **Device tab length note:** The Device tab now has 6 collapsible sections (Sync Timers, Health,
+  Native OS, Wallpaper, Launch Timing, Updates). Consider moving Launch Timing + a future Kill
+  Apps control into a dedicated **"Presentation"** section or a fourth tab to keep Device focused
+  on machine/OS concerns rather than per-app launch behavior.
+- [x] **[Launcher] Launcher config UI — launch_profiles editor (2026-05-14)** — Launch Timing section in `launcher_cfg_launch_timing.svelte` exposes per-profile `post_delay_ms` overrides with Save/Reset per row. PATCHes `event_device.other_json.launcher.launch_profiles` via V3 CRUD. Wired into `launcher_cfg.svelte`. Shown under Technical Mode (`$ae_loc.edit_mode`).

   slideshow mode, error fallback works.

-### [PWA] Service worker ignoring `chrome-extension://` requests
-Browser console shows repeated errors:
-```text
-TypeError: Failed to execute 'put' on 'Cache': Request scheme 'chrome-extension' is unsupported
-```
-The service worker's fetch/install handler is trying to cache requests with `chrome-extension://`
-URLs (injected by browser extensions), which the Cache API rejects. Fix: filter out non-`http`/`https`
-requests before attempting to cache. In the service worker fetch handler, add a guard:
-```js
-if (!event.request.url.startsWith('http')) return; // skip chrome-extension:// etc.
-```
-Locate in `static/service-worker.js` or the Vite PWA plugin config. Low severity — doesn't break
-functionality, but pollutes the console and may cause unhandled promise rejections.
+### ~~[PWA] Service worker ignoring `chrome-extension://` requests~~ ✅ Fixed (2026-05-14)
+Guard added to `src/service-worker.js` fetch handler: `if (!event.request.url.startsWith('http')) return;`
+Also skips cross-origin requests entirely (origin check). No console errors from extension URLs.
