jakman85andClaude Opus 4.8 bc4519bc4c Phase-6: enable Gitea Actions, in-cluster act_runner, static CI gate
STEP 1 — enable Gitea Actions: pin GITEA__actions__ENABLED=true and
DEFAULT_ACTIONS_URL=github in the gitea bootstrap patch (was implicit upstream
default; make it a declared property).

STEP 2 — deploy + register an act_runner in a dedicated non-app namespace
(gitea-actions) so the privileged DinD executor sidecar is admitted without a
Kyverno policy exception (restrict-host-namespaces scopes to app namespaces only).
Docker executor + DinD sidecar over a shared TLS-cert emptyDir; runner state on a
Longhorn PVC (registers once). Registration token delivered as a SOPS-encrypted
Secret decrypted by Flux. Runner mounts no ServiceAccount token (R-SEC-02).

STEP 3 — author .gitea/workflows/gate.yml: the live enforced merge gate running
the STATIC layers (spec-immutability best-effort, lint, Kyverno L0, L1 render) via
`make -C ci lint l0 l1` with the pinned toolchain installed at job start. L2/L3
conformance is an if:false placeholder (needs a toolchain image + scoped cluster
creds — a design decision, not wired). merge-gate.yaml reduced to workflow_dispatch
(dormant full-pipeline blueprint). install-tools.sh gains check-jsonschema so the
schema stage validates in CI instead of skipping.
