+   only on first run, never show up in the debug build or on a device that
+   already granted the calendar permission (this is how the v2.7.0 launch

+   with a `.releasetest` suffix so it installs alongside the real app) and resets
+   it to a first-run state. Then, on the device:
+   - launch from a **clean / permission-not-granted** state — the permission
+     screen must appear, no crash;
+   - grant access — the calendar must load;
+   - add both home-screen **widgets** and confirm they render;
+   - exercise this release's headline changes.
+
+   Only proceed once all of that passes on-device.
+5. **Merge `release/vX.Y.Z` into `main`.** That's it — no manual tagging. The
+   merge triggers `release.yaml`, which detects the new version, builds, signs,
+   publishes to F-Droid, and creates the `vX.Y.Z` tag + Gitea release. **Hold UI

 ## What the pipeline does
 
-`release.yaml` has three jobs:
+CI and release are split so a change is built once on its PR and only does
+release work when a merge actually cuts a release:
 
-- **ci** — unit tests + a debug assemble (sanity).
+- **`ci.yaml`** (on `pull_request`) — lint + unit tests + a debug assemble (and
