# Every push, on every branch — not just main — so build breakage shows up
# on the first commit of a branch, not only once a PR targets main. No
# separate pull_request trigger: for a PR from a branch on this same repo,
# push already fires on that branch, and GitHub attaches the run to the PR
# by commit SHA regardless of which event triggered it — adding
# pull_request too would just run every job twice per push. (Re-add it,
# scoped to forks, only if this repo starts accepting fork PRs — push
# events from a fork never reach here.)

  # one: this repo's Forgejo `act` runner does not keep a `services:`
  # container as the *same* instance across a job's steps, so `migrate
  # deploy` would land the schema in one Postgres and `pnpm --filter api
  # test`'s `beforeAll` would then hit an empty one ("table … does not
  # exist" right after "migrations successfully applied"). One long-lived
  # container in the job, shared by every step, removes that failure mode.

  # Builds and packages a signed, downloadable Android APK on every push to
  # `main` — issue #64. `needs:` on every other job is what actually makes
  # this "build, TEST, and package" rather than just "build and package in
  # parallel with tests that might still be failing": Forgejo/GitHub Actions
  # has no native way for a job in a *different* workflow file to block on
  # one here, so this has to live in this same file to get a real dependency
  # rather than a same-push coincidence. `if:` (not a separate trigger) keeps
  # every other job running on every branch as today — only this one is
  # main-only.
  #
  # No dedicated Android test suite exists (zero native code beyond the
  # Capacitor-generated shell) — "testée" is satisfied by gating on the 5
  # existing jobs, not by inventing an instrumented test suite for this.
  #
  # Unverified on this runner as of writing: no Android build has ever run
  # on this self-hosted Forgejo `act` runner (unlike lint/test/build/e2e,
  # exercised for months). If SDK installation turns out too slow/heavy here,
  # cache `~/.android/sdk`/`~/.gradle` (same idea as the Cypress binary cache
  # in `e2e` above) rather than accepting a slow job on every push.
