# Jobs that use the shared Docker daemon or secrets (test-integration, test-mcp,
# build-and-push) do not run for pull requests from forks: a fork controls the
# workflow and test code, and access to the daemon is root-equivalent on the
# host. Also enable "require approval for workflows from forks" in Gitea.
#
# Every third-party action is pinned to a full commit SHA (the version is in the
# trailing comment); bump deliberately.
#
# Docker hygiene on the shared runner: every resource this workflow creates has
# a per-run name (aegis-ci-<run id>-...) and is removed by an `if: always()`
# step that deletes exactly those names. Nothing here ever prunes.

@@ -132,3 +132,25 @@ The workflows in `.gitea/workflows/` lint, test and build. The `docs-check` job
`uv run python scripts/check_docs.py`, which fails when `docs/tools.md` or the README tool summary
is stale, or when a document names a tool that does not exist. `scripts/generate_catalog.py
--check` fails when `tools.json` does not match the pinned swagger.
Security rules of the pipeline:
- Jobs that use the runner's Docker daemon or a secret (`test-integration`, `test-mcp`,
`build-and-push`) do not run for pull requests from forks. Access to the daemon is
root-equivalent on the host, and a fork controls the workflow and test code. Also enable
"require approval for workflows from forks" (or the equivalent runner setting) in Gitea, and
keep the daemon of a shared runner free of services you cannot afford to lose.
- Every third-party action is pinned to a full commit SHA with the version in a trailing
comment. Bump a pin deliberately: look up the SHA of the new tag with
`git ls-remote https://github.com/<owner>/<action> refs/tags/<tag>` (add `^{}` for annotated
tags). The registry token never reaches a third-party action: the CLI reads it from stdin and
`uv publish` reads `UV_PUBLISH_PASSWORD`.
- `build-and-push` scans the built image with a pinned Trivy (`scripts/ci/install_trivy.sh`,
sha256 verified) before anything is pushed, and fails on HIGH or CRITICAL findings that have a
fix. `scan.yml` repeats the scan and the dependency audit every week, so a new advisory in a
pinned base image turns it red: refresh the digests in `docker/Dockerfile`. Accepted findings
go in `security/trivyignore.txt` with a waiver row in [security.md](security.md).
- `publish.yml` needs the `security` job (secret scan, security tests, dependency audit, bandit
rules) as well as lint and tests.
- The cleanup script removes containers only for per-run image names (`aegis-ci-<run id>-...`)
and immutable `:sha-` tags. Shared tags (`:latest`, `:main`, `:dev`) are only untagged.
