# ecosystem-selftest — proves the foundation's ecosystem-CI capabilities on its own
# runner (documentation/999_testing.md), without depending on external candidate
# repos. Three self-contained jobs, each asserting an acceptance criterion:
#   - semantic-release: the bump sequence 1.0.0→1.1.0→1.1.1→2.0.0→3.0.0
#   - eslint-gate:      an eslint error makes the job exit non-zero
#   - yamllint-gate:    a yamllint error makes the job exit non-zero
# Build-shape coverage (npm/bun/docker) is exercised by the reusable-* workflows
# against the real candidate repos; this file guards the capabilities that need no
# external repo. Runs in the baked foundation-ci image.
