 ## [Unreleased]

-## [2.7.5] — 2026-06-21
-
-### Changed
- Further build cleanup for the official F-Droid repository: stopped embedding
-  AGP's dependency-metadata block in the APK, which F-Droid's reproducible-build
-  scanner rejects as an extra signing block. No functional or visible changes —
-  the same app as 2.7.4, just without that Play-oriented metadata blob.
-
-## [2.7.4] — 2026-06-21
-
-### Changed
- Build cleanup that lets Calendula ship in the official F-Droid repository:
-  removed an unused Gradle toolchain-resolver plugin, which F-Droid's offline,
-  reproducible build process disallows. No functional or visible changes — this
-  is the same app as 2.7.3.
-
-## [2.7.3] — 2026-06-21
-
-### Fixed
- Home-screen widgets no longer get stuck on a loading spinner in the published
-  (F-Droid) release build. They render via Android's background-work system, and
-  release optimisation (R8) was stripping a helper class it loads by name, so the
-  render job never ran. Added the missing keep rule — widgets now load normally.
-
-## [2.7.2] — 2026-06-21
-
-### Added
- Crash reporting you control. If Calendula closes unexpectedly, it now captures
-  a technical report and, on the next launch, offers to send it as an issue on
-  the project's tracker. Nothing is uploaded automatically — the report stays on
-  your device until you choose to share it, it contains no personal data or
-  calendar content (only the app, Android and device versions plus the stack
-  trace), and you see the full text before sending. There's also a "Report a
-  problem" entry in Settings, and if the app ever fails to start repeatedly, a
-  minimal recovery screen still lets you send the report.
-
-## [2.7.1] — 2026-06-21
-
-### Fixed
- Fixed the app crashing immediately on launch whenever calendar access hadn't
-  been granted yet (a fresh install, or after revoking the permission). The app
-  set up its live calendar-change listener before the permission screen could
-  appear, which newer Android versions reject outright — so the app died before
-  you could grant access. The listener now waits for the permission and attaches
-  itself the moment it's granted.
-
 ## [2.7.0] — 2026-06-18

 # Releasing Calendula

-Calendula is distributed through a self-hosted F-Droid repository. A release is
-built, signed, and published automatically by `.gitea/workflows/release.yaml`
-when a **bumped `versionName` reaches `main`** — the pipeline then creates the
-matching `vX.Y.Z` tag and Gitea release itself.
+Calendula is distributed through a self-hosted F-Droid repository. Every
+release is built, signed, and published automatically by
+`.gitea/workflows/release.yaml` when a version tag is pushed.

-## Versioning — the committed version is the source of truth
+## Versioning — the git tag is the single source of truth

-A release is defined by the `versionName`/`versionCode` committed in
-`app/build.gradle.kts`:
+A release is defined by its tag, `vMAJOR.MINOR.PATCH` (e.g. `v2.1.0`). At
+release time the workflow derives both Gradle fields from the tag:

- `versionName` = `MAJOR.MINOR.PATCH` (e.g. `2.1.0`)
+- `versionName` = the tag without the leading `v` (`2.1.0`)
 - `versionCode` = `MAJOR*10000 + MINOR*100 + PATCH` (`2.1.0` → `20100`)

-So `MINOR` and `PATCH` each have room for 0–99. The release pipeline reads
-`versionName`, pins `versionCode` to the derived value, builds, and — once the
-APK is published — creates the tag `v<versionName>` at that commit. The tag is
-an **output** of a successful release, not its trigger, so a tag always marks a
-fully-shipped version (and a failure before publish leaves no tag, so re-running
-the workflow safely retries).
+So `MINOR` and `PATCH` each have room for 0–99. The values committed in
+`app/build.gradle.kts` are only the dev/local default — CI overwrites them
+from the tag. Keep the committed `versionCode`/`versionName` matching the
+**latest released tag** so local builds are sanely versioned; the published
+value always comes from the tag.

 Published version codes so far: `v0.1.0`→100 … `v1.0.0`→10000 … `v2.0.0`→20000.

 ## Cutting a release

-1. **Assemble the release branch.** Create `release/vX.Y.Z` and merge the
-   feature/fix branches that make up this release into it. This branch is the
-   release candidate — everything below happens on it, before it reaches `main`.
-2. Move the `## [Unreleased]` section of `CHANGELOG.md` under a new
+1. Move the `## [Unreleased]` section of `CHANGELOG.md` under a new
   `## [X.Y.Z] — <date>` heading (Keep a Changelog format). The text between
   that heading and the next `## [` becomes both the Gitea release notes and
   the F-Droid per-version changelog.
-3. Bump the committed `versionName` (and `versionCode`) in
-   `app/build.gradle.kts` to the new version. **This bump is what triggers the
-   release** when the branch merges to `main`. Then run
+2. Optionally bump the committed `versionCode`/`versionName` in
+   `app/build.gradle.kts` to match the new version (keeps local builds tidy).
+3. Commit, then tag and push:
   ```bash
-   scripts/sync_changelog_to_fastlane.sh
+   git tag vX.Y.Z
+   git push origin vX.Y.Z
   ```
-   and commit the generated
-   `fastlane/metadata/android/en-US/changelogs/<versionCode>.txt`. This is what
-   makes the **official** F-Droid repo show this version's changelog (it reads
-   the changelog from the tagged source tree). The self-hosted pipeline
-   regenerates it regardless, so forgetting only affects the official listing.
-4. **Verify the release build on a real device** — the mandatory gate. The
-   shipped APK is R8-shrunk/obfuscated, and bugs that only appear there, or
-   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
-   crash slipped through). Run:
-   ```bash
-   scripts/verify-release.sh
-   ```
-   It builds the `releaseTest` variant (same R8 config as `release`, debug-signed
-   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
-   releases for on-device review and explicit go-ahead before merging.**
-
-> The `releaseTest` build type exists only for step 4 — it is never published.
-> The pipeline always builds and signs the real `release` variant.
+4. The push triggers the release workflow. **Hold UI releases for on-device
+   review and explicit go-ahead before tagging.**

 ## What the pipeline does

-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:
+`release.yaml` has three jobs:

- **`ci.yaml`** (on `pull_request`) — lint + unit tests + a debug assemble (and
-  a Trivy scan), once per PR. Docs/metadata-only PRs skip the Android build but
-  still report a green `CI` check.
- **`release.yaml`** (on push to `main`, plus `workflow_dispatch`) — a cheap
-  `detect` job reads `versionName` and checks whether a tag for it already
-  exists. Only when it doesn't does the `release` job run: unit tests on the
-  merged commit, build & sign the release APK with the **app key**, copy it into
-  the F-Droid repo, generate the per-version changelog, re-sign the index with
-  the **repo key**, upload `repo/` + `metadata/`, then create the `vX.Y.Z` tag +
-  Gitea release (CHANGELOG section as notes) and attach the R8 `mapping.txt`
-  (best-effort). Ordinary merges with no version bump fall through `detect` and
-  do nothing.
+- **ci** — unit tests + a debug assemble (sanity).
+- **build-and-deploy** — derives the version, builds & signs the release APK
+  with the app key, copies it into the F-Droid repo, generates the per-version
+  changelog, re-signs the F-Droid index with the **repo key**, uploads
+  `repo/` + `metadata/` to the box, and attaches the R8 `mapping.txt` to the
+  Gitea release (best-effort).
+- **gitea-release** — creates/updates the Gitea release carrying the tag's
+  CHANGELOG section as notes. Gated on `ci` only (not the deploy) so notes
+  publish even if the F-Droid upload hiccups.

 ### Manual re-sign / recovery

-A manual `workflow_dispatch` of the release workflow runs a **re-sign-only**
-path: `detect` reports it's not a release, so the `release` job skips the APK
-build, the version bump, and tag/release creation, and just re-signs the
-existing F-Droid index with the configured repo key and re-uploads. Use this
-for key rotation or repo recovery without publishing a new app version.

-# Official F-Droid submission (draft)
-
-Goal: publish Calendula to the **official F-Droid repo** *alongside* the
-self-hosted repo, as **one app** — same signed binary in both channels, so
-existing self-hosted users migrate with no reinstall and no data loss.
-
-This folder holds the **draft** fdroiddata recipe. Nothing here is submitted
-yet. The self-hosted pipeline (`../../fdroid-metadata/`, `.gitea/workflows/release.yaml`)
-is unaffected by these files.
-
-## Publishing model: reproducible build + developer-signed binary
-
-F-Droid builds Calendula from source on its buildserver, then verifies the
-output is byte-for-byte identical to **our** signed APK (fetched via the
-`Binaries` URL). On a match it publishes **our** binary, signed with **our**
-key — identified by `AllowedAPKSigningKeys`. Result: official and self-hosted
-both carry the same signature. If a build ever fails to match, F-Droid simply
-skips that version (fails safe — no bad publish).
-
-## Verification status (2026-06-21)
-
- ✅ **Run-to-run reproducible** — `v2.7.0` built twice from a clean worktree
-  (R8 minify + resource-shrink, build cache off) → byte-for-byte identical
-  (`sha256 568c944a…`).
- ✅ **Cross-JDK reproducible** — rebuilt with JDK 17 and JDK 21 → identical
-  APK. JDK version is not a sensitivity, so it need not be pinned.
- ✅ **Tag self-consistent** — committed `versionCode`/`versionName` already
-  equal the tag-derived values, so F-Droid building the tag as-is matches the
-  CI-published binary (CI's `sed` substitution is a no-op).
- ✅ **App signing cert SHA-256 extracted** from published APKs (identical
-  across v1.0.0 / v2.0.0 / v2.4.0): `5cdaee8e…`. No keystore needed.
- ✅ **Eligibility** — MIT, 100% FOSS deps (no Play Services / Firebase /
-  analytics / billing), no `INTERNET` permission, no native code.
- ✅ **End-to-end reproducible vs the DISTRIBUTED binary** — built tag `v2.7.1`
-  from source and compared against the published `calendula_v2.7.1.apk`: every
-  app entry (dex / resources / assets / manifest) byte-identical. The only
-  difference was `META-INF/version-control-info.textproto` (AGP's git metadata,
-  env-dependent). Fixed with `vcsInfo { include = false }` on the release build;
-  re-validated → 0 non-signature differences. **Takes effect from the first
-  release built after that change — submit the recipe starting at that version**
-  (v2.7.1 and earlier still embed the textproto and won't verify).
- ⚠️ **Not yet proven**: cross-host / fixed-build-path reproducibility on
-  F-Droid's buildserver (low risk for a no-NDK pure-JVM app; with vcsInfo
-  disabled, the env-dependent field is gone; F-Droid confirms at review).
- ✅ **Buildserver toolchain supported** (checked 2026-06-21):
-  - **Gradle 9.5.1** is in F-Droid's gradle-transparency-log (`checksums.json`)
-    with a verified sha256, so `gradlew.py` will download + verify + run it.
-  - **AGP 9.2** is in `gradlew.py`'s `MIN_GRADLE_VERSION` map (`9.2 -> 9.4.1`).
-  - **JDK 17** is standard on the buildserver (AGP 9.2 requires exactly 17).
-  - **build-tools 36.0.0 / android-37**: not statically preinstalled (baseline
-    stops at 33), but `provision-android-sdk` makes `$ANDROID_HOME/build-tools`
-    and `/platforms` group-writable so AGP/Gradle install newer ones on demand.
-
-## Before submitting — checklist
-
-1. Confirm the `Binaries` URL is publicly reachable and stable long-term, e.g.
-   `https://apps.dev.jeanlucmakiola.de/dev/fdroid/repo/calendula_v2.7.0.apk`
-   resolves to the dev-signed APK. F-Droid re-fetches it on every build.
-2. Confirm F-Droid's buildserver supports the toolchain (see timing risk).
-3. (Recommended) Reproduce one published release end-to-end: build the tag from
-   source, strip signatures, and diff against the downloaded `calendula_v<ver>.apk`
-   to confirm the from-source build matches the *distributed* binary — not just
-   another local build.
-
-## Submission steps (fdroiddata, GitLab)
-
-1. Fork `https://gitlab.com/fdroid/fdroiddata`.
-2. Copy `de.jeanlucmakiola.calendula.yml` to `metadata/` in the fork.
-3. Test locally with `fdroid build -v de.jeanlucmakiola.calendula` and
-   `fdroid lint de.jeanlucmakiola.calendula` (and `fdroid readmeta`).
-4. Open a Merge Request. Initial review can take weeks to months; the
-   self-hosted repo keeps serving in the meantime, so there's no rush.
-
-## Listing metadata (descriptions, screenshots, icon)
-
-These are **not** in the recipe `.yml`. F-Droid's `fdroid update` harvests them
-automatically from the fastlane tree in the app's source repo:
-
-    fastlane/metadata/android/<locale>/
-      short_description.txt   full_description.txt   title.txt
-      images/icon.png         images/phoneScreenshots/*.png
-      changelogs/<versionCode>.txt   (optional, per release)
-
-This is the single source of truth: en-US + de-DE already exist there, and the
-self-hosted repo is generated from the same tree at release time via
-`scripts/fastlane_to_fdroid_localized.sh`. Nothing extra to add to fdroiddata —
-F-Droid picks the listing up from source. (Screenshots may not be committed to
-the fdroiddata repo anyway, so the source-tree fastlane layout is required.)
-
-Per-version changelogs: the self-hosted release workflow generates
-`changelogs/<versionCode>.txt` at release time. For the official repo to show a
-changelog, that file must be committed into `fastlane/metadata/android/<locale>/changelogs/`
-at the tagged commit — wire this into the release/version-bump step, or accept
-no in-client changelog for the official listing initially.

-### Fixed
- Fixed the app crashing immediately on launch whenever calendar access hadn't
-  been granted yet (a fresh install, or after revoking the permission). The app
-  set up its live calendar-change listener before the permission screen could
-  appear, which newer Android versions reject outright — so the app died before
-  you could grant access. The listener now waits for the permission and attaches
-  itself the moment it's granted.

- Home-screen widgets no longer get stuck on a loading spinner in the published
