+# Hermes Nix CI Gate
+
+Hermes keeps a Nix gate in CI to validate the packaging surface that is easy to
+break accidentally:
+
+- `flake.nix` evaluation
+- the Hermes package build
+- the NixOS module and config roundtrip checks
+- npm lockfile hash drift diagnostics for the bundled web/TUI packages
+
+Nix is not required to run Hermes. It is a CI and packaging tool for people who
+consume Hermes through Nix or maintain the release packaging.
+
+## Runner Contract
+
+The Molecule Gitea runner pool currently exposes Linux runners only. The Nix
+workflow therefore runs on `ubuntu-latest`; do not add a macOS required context
+unless a live macOS Gitea runner exists and is protected by the same branch gate.
+
+The runner image does not include Nix. CI installs it through the pinned
+`DeterminateSystems/nix-installer-action` revision in
+`.github/actions/nix-setup/action.yml`. That action must also exist in the
+Gitea action mirror so CI does not depend on GitHub availability.
+
+Cachix is configured as a best-effort cache. A cache outage can make the job
+slower, but it must not decide pass/fail. The required checks are the flake and
+package build steps.
+
+## Timeout Policy
+
+Cold Gitea runners may need to build the Nix graph without a populated cache.
+The workflow timeout is intentionally set to 60 minutes so cold-cache builds can
+finish while still bounding stuck jobs.
+
+If the Nix job times out, check the log tail first:
+
+- active build output near the end usually means a cold-cache timeout; raise the
+  cache hit rate or split the check before changing product code
+- a completed build followed by `nix run .#fix-lockfiles -- --check` failure
+  usually means committed npm lockfile hashes are stale
+- installer or mirror failures point at runner bootstrap or action mirror drift
+
+## Debugging and Observability
+
+When a Nix CI failure is not self-explanatory from the Gitea job log, use the
+central observability stack before SSH-grepping individual runners. Runner,
+operator, and tenant logs are shipped to Molecule Loki/Grafana. Useful failure
+classes to search for:
+
+- action mirror fetch failures
+- Nix installer failures
+- Cachix connectivity or auth failures
+- runner job cancellation or timeout events
+- disk pressure during Nix store builds
+
+The workflow should keep emitting enough log context to classify those failures
+without needing a rerun. If a future fix touches the runner bootstrap, add
+diagnostic output there as part of the same change so the next red main has a
+clear owner and root cause.
