+# Android release pipeline
+
+Android releases use two independent credentials:
+
+- the upload keystore signs the APK and AAB;
+- a short-lived Google access token publishes the AAB through the Play
+  Developer API.
+
+The GitHub release workflow expects these encrypted secrets:
+
+- `ANDROID_UPLOAD_KEYSTORE_BASE64`
+- `ANDROID_UPLOAD_KEYSTORE_PASSWORD`
+- `ANDROID_UPLOAD_KEY_ALIAS`
+- `ANDROID_UPLOAD_KEY_PASSWORD`
+
+It also expects this repository variable:
+
+- `ANDROID_UPLOAD_CERT_SHA256`
+
+The protected `play-closed-testing` GitHub Environment supplies:
+
+- `PLAY_APP_SIGNING_CERT_SHA256`
+- `GCP_WORKLOAD_IDENTITY_PROVIDER`
+- `GCP_PLAY_SERVICE_ACCOUNT`
+- `PLAY_PACKAGE_NAME` (`com.vnidrop.app`)
+- `PLAY_CLOSED_TRACK` (the existing closed-test track identifier)
+
+The upload and app-signing certificate fingerprints are public identifiers from
+Play Console's App signing page. Do not store a private key in a repository
+variable.
+
+`packaging/android/build-release.sh` creates an upload-signed AAB and APK,
+verifies their canonical version and upload certificate, and writes checksums.
+The release workflow uploads only the AAB to Play. It then downloads the
+universal APK generated and signed by Play for the public GitHub Release.
+
+Play publishing is deliberately restricted to `draft` releases on
+`PLAY_CLOSED_TRACK`. Production promotion is not part of this pipeline.
+
+## One-time setup
+
+1. In Play Console, link a Google Cloud project and grant the deployment
+   service account permission to manage releases for VniDrop.
+2. In Google Cloud, enable the Google Play Android Developer API and configure
+   a Workload Identity Federation provider that trusts this repository's
+   GitHub Actions identity. Permit the service account to receive federated
+   tokens from that provider.
+3. Create the `play-closed-testing` GitHub Environment. Add the five variables
+   listed above and restrict deployment branches/tags to the release policy.
+4. Add the four upload-keystore secrets and
+   `ANDROID_UPLOAD_CERT_SHA256` in the repository settings.
+
+No Google service-account JSON key is stored in GitHub. The workflow exchanges
+GitHub's OIDC identity for a short-lived Google access token.

+# Coordinated releases
+
+Only `.github/workflows/release.yml` responds to version tags. It verifies that
+the tag matches `version.properties` and points at the current `master`, then
+calls the native platform workflows in parallel.
+
+The tag workflow runs only when the repository variable
+`RELEASE_PIPELINE_ENABLED` is exactly `true`. Leave it unset or set it to
+`false` to disable all coordinated releases, including Play uploads, without
+disabling release validation on pull requests.
+
+Platform workflows upload private workflow artifacts. After every native build
+passes, the release pipeline:
+
+1. stages the signed AAB as a draft on the configured Play closed-test track;
+2. downloads the universal APK signed by Play;
+3. verifies and assembles the public artifacts;
+4. generates checksums and GitHub build-provenance attestations;
+5. creates exactly one GitHub Release;
+6. updates the Homebrew cask.
+
+Public GitHub Release assets are the DEB, RPM, notarized DMG, Sparkle appcast,
+Play-signed universal APK, checksum file, and release manifest.
+
+The unsigned Microsoft `.msixupload` and upload-signed Android AAB remain
+private workflow artifacts. Partner Center submission stays manual until the
+first Microsoft Store release is certified. The Play release remains a draft
+on a closed-testing track; this pipeline cannot publish to production.
+
+To release, first update and merge `version.properties`, including a monotonic
+Android version code. Apple Store and Direct build numbers are derived
+independently at build time. Then create and push the matching tag:
+
+```bash
+git tag -s v0.2.0 -m "VniDrop 0.2.0"
+git push origin v0.2.0
+```
+
+The tag must point at the current `origin/master` commit. A failed run creates
+no GitHub Release; a rerun safely reuses an already-staged Play draft only when
+the version, configured track, draft status, and app-signing certificate all
+match.

+# Application versioning
+
+`version.properties` at the repository root is the single source of truth for
+the VniDrop product version and persistent store counters. Platform projects
+and release workflows use the version resolver rather than accepting
+independent version overrides.
+
+Keep it as plain `KEY=VALUE` assignments: the same file is parsed by shell,
+PowerShell, Gradle, and Rust. Xcode receives resolver-generated xcconfig files.
+
+The product uses numeric semantic versions. While the app is in beta, feature
+releases increment the minor component (`0.2.0`, `0.3.0`) and fixes increment
+the patch component (`0.2.1`). Release channels belong in
+`RELEASE_CHANNEL`; they are not appended to store version fields.
+
+| Platform | Product version | Platform build/package version |
+| --- | --- | --- |
+| Android | `PRODUCT_VERSION` | `ANDROID_VERSION_CODE` |
+| Apple Store | `PRODUCT_VERSION` | Derived UTC `YYYYMMDD.HHMM.SS` |
+| Direct macOS | `PRODUCT_VERSION` | Independently derived UTC `YYYYMMDD.HHMM.SS` |
+| Linux | `PRODUCT_VERSION` | Native package revision |
+| Rust handshake | `PRODUCT_VERSION` | Rust crate version remains independent |
+| Microsoft Store | `PRODUCT_VERSION` in the app | Derived MSIX dot-quad |
+
+MSIX requires a non-zero first component and reserves the fourth component for
+the Store. Its version is:
+
+```text
+(product major + WINDOWS_VERSION_EPOCH).product minor.product patch.0
+```
+
+With epoch `1`, product `0.2.0` maps to MSIX `1.2.0.0`, while product `1.0.0`
+maps to `2.0.0.0`. Do not change the epoch after publishing.
+
+Every Android upload must increment `ANDROID_VERSION_CODE`. Apple build numbers
+are derived at build time by `apple-store-build` and `apple-direct-build`; they
+are kept as separate resolver outputs so App Store and Sparkle releases do not
+consume each other's cadence. Every changed Windows Store package must
+increment the product version because the Store-reserved fourth component
+cannot carry a rebuild number.
+
+Apple projects read generated build settings rather than `version.properties`
+directly:
+
+```bash
+packaging/version/generate-apple-xcconfig.sh all
+```
+
+The generated files under `apple/Generated/` are intentionally ignored.
+`VNIDROP_BUILD_TIME_UTC=YYYYMMDDHHMMSS` provides a deterministic clock for
+tests; distribution builds normally use the current UTC time.
+
+Before releasing:
+
+```bash
+make check-version
+```
+
+Release tags must exactly match `vPRODUCT_VERSION`. Manual workflow dispatches
+also build the committed version and do not accept free-form version inputs.
