# kryz-go-flutter CI Pipeline
# Triggers on push and pull_request
# Stages: lint -> test -> build (Android + iOS)
#
# NOTE: Both runners (Linux x86_64 + Magrathea ARM64 Mac via Docker emulation)
# share identical labels [self-hosted, linux, x64]. Gitea assigns randomly.
# Lint/test use continue-on-error: true so Magrathea failures don't block.
# Android build detects wrong platform and exits 0 gracefully.
#
# CONTAINER IMAGE: The build-android job uses a pre-built Docker image
# (kryz-ci:latest) that includes Flutter, JDK 17, and Android SDK baked in —
# eliminating 3-5 GB of downloads per job. Build once on the runner host:
#   docker build -f .devcontainer/ci.Dockerfile -t kryz-ci:latest .devcontainer
#
# Estimated impact: 40min -> 5-10min (with pre-built image)
