-# VEX Ops Runbook — Draft Skeleton (2025-12-05 UTC)
+# VEX Ops Runbook (dev-mock ready)
 
-Status: draft placeholder. Inputs pending: DevOps rollout plan for signatures/ops.
+Status: DRAFT (2025-12-06 UTC). Safe for dev/mock exercises; production rollouts wait on policy/VEX final digests.
 
-## Recompute Storms
-- Steps to mitigate; throttling knobs (to fill).
+## Pre-flight (dev vs. prod)
+1) Release manifest guard
+   - Dev/mock: `python ops/devops/release/check_release_manifest.py deploy/releases/2025.09-mock-dev.yaml --downloads deploy/downloads/manifest.json`
+   - Prod: rerun against `deploy/releases/2025.09-stable.yaml` once VEX digests land.
+2) Render plan
+   - Helm (mock overlay): `helm template vex-mock ./deploy/helm/stellaops -f deploy/helm/stellaops/values-mock.yaml --debug --validate > /tmp/vex-mock.yaml`
+   - Compose (dev with overlay): `USE_MOCK=1 deploy/compose/scripts/quickstart.sh env/dev.env.example && docker compose --env-file env/dev.env.example -f deploy/compose/docker-compose.dev.yaml -f deploy/compose/docker-compose.mock.yaml config > /tmp/vex-compose.yaml`
+3) Backups (when touching prod data) — not required for mock, but in prod take Mongo snapshots for issuer-directory and VEX state before rollout.
 
-## Mapping Failures
-- Triage steps; retry/backfill guidance.
+## Deploy (mock path)
+- Helm dry-run already covers structural checks. To apply in a dev cluster: `helm upgrade --install stellaops ./deploy/helm/stellaops -f deploy/helm/stellaops/values-mock.yaml --atomic --timeout 10m`.
+- Observe VEX Lens pod logs: `kubectl logs deploy/vex-lens -n stellaops --tail=200 -f`.
+- Issuer Directory seed: ensure `issuer-directory-config` ConfigMap includes `csaf-publishers.json`; mock overlay already mounts default seed.
 
-## Signature Errors
-- Diagnosis workflow; key rotation checks.
+## Rollback
+- Helm: `helm rollback stellaops 1` (choose previous revision). Mock overlay uses `stellaops.dev/mock: "true"` annotations; safe to tear down after tests.
+- Compose: `docker compose --env-file env/dev.env.example -f docker-compose.dev.yaml -f docker-compose.mock.yaml down`.
+
+## Troubleshooting
+- Recompute storms: throttle via `VEX_LENS__MAX_PARALLELISM` env (set in values once schema lands); for now scale deployment down to 1 replica to reduce concurrency.
+- Mapping failures: capture request/response with `kubectl logs ... --since=10m`; rerun after clearing queue.
+- Signature errors: confirm Authority token audience/issuer; mock overlay uses the same auth settings as dev compose.
+
+## Evidence capture
+- Save `/tmp/vex-mock.yaml` and `/tmp/vex-compose.yaml` with the manifest used.
+- `kubectl get deploy/pod,svc -n stellaops -l app=vex-lens -o yaml > /tmp/vex-live.yaml`.
+- Tarball: `tar -czf vex-evidence-$(date -u +%Y%m%dT%H%M%SZ).tar.gz /tmp/vex-*`.
 
 ## Open TODOs
-- Add concrete commands and dashboards once rollout plan is delivered.
+- Replace mock digests with production pins and add env/schema knobs for VEX Lens once published.
+- Add Grafana panels for recompute throughput and mapping failure rate after metrics are exposed.
