# Release automation for git.comunes.org (Forgejo Actions).
#
# Pushing a tag `v*` runs two independent jobs:
#   play            - build the signed AAB and ship it to Google Play (production, 100%).
#   fdroid_reference- build the per-ABI reference APKs the SAME way F-Droid will
#                     (fdroid build inside the fdroidserver buildserver image),
#                     sign them with the tane-upload key, and attach them to the
#                     Forgejo release. F-Droid re-runs `fdroid build` on the same
#                     commit+recipe+image, gets byte-identical output, verifies our
#                     signature (AllowedAPKSigningKeys) and publishes OUR APK — so
#                     F-Droid and Play share the same signing key.
#
# All credentials come from repo secrets (Settings > Actions > Secrets):
#   TANE_KEYSTORE_BASE64   base64 of the dedicated tane-upload.jks
#   TANE_KEYSTORE_PASSWORD store password
#   TANE_KEY_ALIAS         tane-upload
#   TANE_KEY_PASSWORD      key password
#   SUPPLY_JSON_KEY_DATA   Google Play service-account JSON
#
# NOTE: `runs-on` must match a label your Forgejo runner registered with.
# fdroid_reference is 3 separate jobs chained with `needs:` (armeabi-v7a ->
# arm64-v8a -> x86_64), NOT a matrix: this runner's act_runner does not honor
# `strategy.max-parallel`, so a matrix always ran all 3 concurrently — 2-3
# simultaneous cold NDK/CMake/Gradle builds contend for RAM and get OOM-killed
# (silent "Gradle build daemon disappeared", no error message). `needs:` is
# core Actions syntax with no such gap, so it actually serializes them. Each
# needs its own full cold NDK+tesseract-native+flutter compile (~30-35min
# alone), which is why they're chained rather than run in one job (that alone
# was too slow even for a 90m timeout).
