# Console Security Checklist Sign-off — 2025-10-27
## Summary
- Security Guild completed the console security compliance checklist from [`docs/security/console-security.md`](../security/console-security.md) against the Sprint23 build.
- No blocking findings. One observability note (raise Grafana burn-rate alert to SLO board) was addressed during the run; no follow-up tickets required.
- Result: **PASS** console may progress with Sprint23 release gating.
## Authority client validation
- Ran `stella authority clients show console-ui` in staging; confirmed `pkce.enforced=true`, `dpop.required=true`, and `claim.requireTenant=true`.
- Verified scope bundle matches §3 (baseline `ui.read`, admin set, and per-feature scopes). Results archived under `ops/evidence/console-ui-client-2025-10-27.json`.
## CSP enforcement
- Inspected rendered response headers via `curl -I https://console.stg.stellaops.local/` CSP matches §4 defaults (`default-src 'self'`, `connect-src 'self' https://*.internal`), HSTS + Referrer-Policy present.
- Helm overrides reviewed (`deploy/helm/stellaops/values-prod.yaml`); no extra origins declared.
## Fresh-auth timer
- Executed Playwright admin flow: promoted policy revisions twice; observed fresh-auth modal after 5minutes idle.
- Authority audit feed shows `authority.fresh_auth.success` and `authority.policy.promote` entries sharing correlation IDs.
## DPoP binding test
- Replayed captured bearer token without DPoP proof; Gateway returned `401` and incremented `ui_dpop_failure_total`.
- Confirmed logs contain `ui.security.anomaly` event with matching `traceId`.
## Offline mode exercise
- Deployed console with `console.offlineMode=true`; Offline banner rendered, SSE disabled, CLI guidance surfaced on runs/downloads pages.
- Imported Offline Kit manifest; parity checks report `OK` status.
## Evidence parity
- Downloaded run evidence bundle via UI, re-exported via CLI `stella runs export --run <id>`; SHA-256 digests match.
- Verified Downloads workspace never caches bundle contents (only manifest metadata stored).
## Monitoring & alerts
- Grafana board `console-security.json` linked to alerts: `ui_request_duration_seconds` burn-rate, DPoP failure count, downloads manifest verification failures.
- PagerDuty playbook references `docs/security/console-security.md` §6 for incident steps.
## Sign-off
- Reviewed by **Security Guild** (lead: `@sec-lfox`).
- Sign-off recorded in Sprint23 tracker (`../implplan/SPRINTS.md`, `DOCS-CONSOLE-23-018`).
