# NOTE: versionCode is the commit count (`git rev-list --count HEAD`), which
# only ever increases and tracks the code rather than the CI file. It replaced
# github.run_number on 2026-08-09: run_number counts workflow RUNS, so it
# resets to 1 if this file is renamed AND it can fall behind a build made
# outside this workflow — which happened, leaving CI unable to install over a
# manually sideloaded APK (INSTALL_FAILED_VERSION_DOWNGRADE). The checkout
# below therefore needs fetch-depth: 0; a shallow clone counts 1 commit.
#
# This job is NOT gated on a test suite: this repo has no Flutter analyze/test
# job to depend on, so a broken commit still publishes. The build failing is
# the only backstop. Add `needs:` here if a Flutter CI job is ever added.
