 ## 🔴 CMSC Charlotte — May 27 (Presentation Management)
 **Drive down:** May 25 | **Setup:** May 26 morning | **Show:** May 27+
 
-- [ ] **[Electron/Launcher] Clean up presentation file launch scripts** — BGH show revealed
-  issues with the scripts used to open/launch presentation files through the Electron Launcher.
-  Audit and improve the launch/open flow (script reliability, error handling, file path resolution).
-  Must be tested and ready before May 26 setup day.
+**[Electron/Launcher] Clean up presentation file launch scripts** — BGH show revealed issues
+with the scripts used to open/launch presentation files. Architecture decision: move launch
+logic to the Svelte side so it can be changed without an Electron rebuild. Electron becomes a
+thin OS primitive layer; all business logic lives in Svelte and device config.
+
+**Electron groundwork (2026-05-11) — DONE:**
+- [x] `run_osascript` hardened — temp `.scpt` file approach; handles multi-line + special chars
+- [x] `native:copy-from-cache-to-temp` primitive added — copy to tmp, caller decides launch
+- [x] `native:launch-from-cache` accepts optional `script_template` — AppleScript or `shell:` prefix; falls back to hardcoded defaults when null
+- [x] `get_launch_script_template()` in `launcher_file_cont.svelte` reads from device config then event config; passes result to `launch_from_cache`
+
+**Svelte-side migration — remaining before May 26:**
+- [ ] **[Launcher] Built-in Svelte default templates** — move the "known good" pptx/key/pdf
+  AppleScript strings out of Electron hardcode and into a Svelte constants file (e.g.
+  `ae_launcher__default_launch_scripts.ts`). Priority: `get_launch_script_template()` already
+  checks device config and event config; add a 3rd fallback to these Svelte defaults before
+  returning `null`. This means Electron's hardcoded defaults become the last-resort only.
+- [ ] **[Launcher] Composable open flow** — refactor `handle_open_file()` to use
+  `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.
+- [ ] **[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_scripts editor** — add a Technical Mode panel
+  in the Launcher config (tabbed settings) to view and edit `launch_scripts` entries on the
+  active device record. PATCH via `event_device` V3 CRUD. Lets OSIT staff tune scripts onsite
+  without needing phpMyAdmin or a code deploy.
+- [ ] **[Launcher] End-to-end test on macOS** — test pptx and key opens on a real podium Mac
+  before May 26 setup day. Verify: file copies to tmp correctly, script fires, app opens in
+  slideshow mode, error fallback works.
