-## 8. Configurable Launch Scripts (No-Rebuild File Handling)
+## 8. Launch Profiles and Native Templates (No-Rebuild File Handling)
+This launcher uses two related concepts:
 
-To avoid requiring a full Electron rebuild for changes to how files are opened, `launch_from_cache`
-supports an optional `script_template` parameter. When provided, Electron runs the template
-instead of its built-in hardcoded logic. The hardcoded logic remains intact as the fallback
-when no template is configured.
+- **Launch Profile**: the Svelte-side config object keyed by file extension. A profile decides
+  which app to use, whether to extend or mirror displays, whether to use an explicit open
+  command, whether to run post-open automation, and how long to wait before running it.
+- **Native Template**: the single AppleScript or shell command string handed to Electron after
+  Svelte resolves the profile. This is what Electron actually executes.
 
-### Template Formats
+The Svelte launcher resolves a profile and then passes a native template string to
+`launch_from_cache`. Electron only executes the template it receives. If Svelte has not
+resolved a template yet, it should stop before IPC and surface a missing-profile error.
+This keeps all fallback logic in Svelte, where it can be edited without rebuilding Electron.
+The native layer should not invent or guess a default launch path.
+
+### Native Template Formats
 
 | Format | Example |
 | :--- | :--- |
 | **AppleScript** (macOS) | Multi-line AppleScript string with `{{path}}` placeholder |
 | **Shell command** | String prefixed with `shell:` — e.g. `shell:open "{{path}}"` |

+**[Electron/Launcher] Clean up presentation file launch profiles** — BGH show revealed issues
+with the profiles 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.
 
+Why this matters: the profile map is policy, while the native template is the exact runtime
+command. Keeping those separate avoids a second hidden source of truth and keeps Electron from
+guessing defaults.
+
 **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`
+- [x] `native:launch-from-cache` executes a provided `native_template` string — AppleScript or `shell:` prefix; no Electron-side fallback
+- [x] `get_launch_profile()` in `launcher_file_cont.svelte` reads from device config then event config; resolves to a `native_template` string and passes it to `launch_from_cache`
