# kryz-go-flutter CI Pipeline
# Triggers on push and pull_request
# Stages: lint -> test -> build (Android + iOS)
#
# NOTE: Both runners share identical labels [self-hosted, linux, x64].
# Lint/test use continue-on-error so failures on one runner don't block.
#
# CONTAINER STRATEGY: Each job checks for a local `kryz-ci:latest` Docker image.
# If missing, it builds once (~25 min). Subsequent jobs find the cached image
# and skip the build entirely. This reduces total pipeline time from ~40 min
# (inline downloads per job) to ~25 min first run / ~5 min cached.
#
# To pre-build the image on your runner:
#   docker build -f .devcontainer/ci.Dockerfile -t kryz-ci:latest .devcontainer
