# Gitea Actions workflow — build/test on every push to main. Gitea Actions uses the same
# workflow syntax as GitHub Actions (a compatible runner), so this is portable if the canonical
# remote ever needs to move CI providers, without being GitHub Actions itself or requiring a
# paid CI provider. Runs against the canonical Gitea repo only — see docs/PHASE4_PRODUCTION_INFRASTRUCTURE.md
# §18 for why this never touches the GitHub kubekosh fork.
#
# Deploy this file to .gitea/workflows/build-and-test.yml at the repo root to activate it (kept
# under infra/ci/ in this PR so it's reviewed alongside the rest of the infra package first,
# per the same "build now, activate deliberately" posture as everything else server-dependent
# in this phase — enabling Gitea Actions on the instance is itself a one-time admin step that
# may not be done yet).
