# Binary Release workflow
#
# This workflow builds platform-specific binaries and creates a GitHub Release
# when a version tag (v*) is pushed. This is the second release channel —
# npm publishing is handled separately by version.yml via changesets.
#
# Release channels:
#   1. npm publish  — handled by version.yml (changesets/action)
#   2. GitHub Release with binaries — handled by this workflow (release.yml)

  # ── Build Android APK/AAB artifacts ──────────────────────────────────
  # FNXC:Release 2026-06-25-12:00:
  # Android release assets used to be limited to the manual mobile workflow's
  # short-lived CI artifacts. Tagged binary releases now build the Capacitor
  # Android shell in this workflow so the public GitHub Release includes a
  # stable APK and checksum beside desktop and CLI binaries.
  # FNXC:Release 2026-06-25-18:10:
  # Android signing is optional and secret-gated on ANDROID_KEYSTORE_BASE64,
  # ANDROID_KEYSTORE_PASSWORD, ANDROID_KEY_ALIAS, and ANDROID_KEY_PASSWORD.
  # The Capacitor Android project is gitignored/regenerated, so CI injects
  # signing with android.injected.signing.* Gradle properties instead of
  # committing native build.gradle edits. When the keystore is absent, keep the
  # FN-7014 unsigned debug APK fallback; Play Store upload remains out of scope
  # and is tracked separately from sideload release artifacts.
