- **`Builds[].commit` must be a full 40-char commit SHA**, not a `v*` tag or branch (reviewer requirement).
- **`AutoName` must stay in the recipe** — `fdroid checkupdates` regenerates it from the manifest and that CI job fails on any resulting diff. (Only `Summary`/`Description` move to Fastlane; `AutoName` does not.)
- **`AllowedAPKSigningKeys`** is the signing cert's SHA-256 (`apksigner verify --print-certs <signed.apk>`, colons stripped, lowercased) — it opts into Reproducible Builds so F-Droid verifies its build against our key instead of re-signing. One-way door; keep it.
- **`Binaries`** is the URL pattern of our own signed release APK (`https://github.com/felipedbene/deburrow/releases/download/v%v/DeBurrow-v%v.apk`, `%v` = versionName). It's the reproducible-build *reference*: F-Droid downloads this developer-signed APK and byte-compares it against its own from-source build; combined with `AllowedAPKSigningKeys` this is what makes the build "verified reproducible". The `release.yml` workflow publishes exactly this asset name/path on each `v*` tag — keep the two in sync.
- Keep `versionName`/`versionCode` in sync with `defaultConfig` in `app/build.gradle.kts` and tag releases as `v<versionName>` (e.g. `v2.0.3`). `UpdateCheckMode: Tags` + `AutoUpdateMode: Version` auto-detects new `v*` tags.
- Validate locally before pushing: `fdroid rewritemeta <pkg>` (must produce no diff — canonical form), `fdroid lint <pkg>`, and `check-jsonschema --schemafile <fdroiddata>/schemas/metadata.json <recipe>`. Pin `ruamel.yaml<0.17.22` in the fdroidserver venv or `rewritemeta` reformats long values (e.g. wraps `AllowedAPKSigningKeys`) differently than CI.
