+# Security Templates
+
+This folder contains host-side security templates for public launch hardening.
+
+## fail2ban (recommended baseline)
+- Config location:
+  - `docker/security/fail2ban/jail.d/fiddy-nginx.conf`
+  - `docker/security/fail2ban/filter.d/fiddy-nginx-auth.conf`
+- Purpose:
+  - ban repeated abusive requests against auth, join, and invite endpoints.
+
+## CrowdSec (optional alternative/complement)
+- Config location:
+  - `docker/security/crowdsec/acquis.yaml`
+- Purpose:
+  - ingest Nginx access/error logs with CrowdSec for broader behavior-based decisions.
+
+## Notes
+- Use either fail2ban or CrowdSec as your primary auto-ban control, or carefully run both with clear ownership of ban actions.
+- Validate log paths match your deployment:
+  - `/var/log/nginx/fiddy-access.log`
+  - `/var/log/nginx/fiddy-error.log`

+- Added restore drill logging artifacts:

+  - `scripts/log-restore-drill.sh` to append timestamped restore outcomes and measured RTO.
+- Added consolidated execution checklist:
+  - `docs/07_PUBLIC_LAUNCH_CHECKLIST.md` for go-live gating across infra, deploy, security, observability, DR, and rollback.
 
 ### Risks / Notes to Revisit
 - Workspace is intentionally dirty; commits must be path-scoped to avoid mixing unrelated changes.

+# Public Launch Checklist
+
+## A) Infrastructure Baseline
+- [ ] Domain DNS points to public IP.
+- [ ] Router forwards only `80` and `443`.
+- [ ] Host firewall denies all inbound except `80/443` and restricted `22`.
+- [ ] `SSH_ALLOW_CIDR` policy validated.
+- [ ] Postgres port `5432` is not public.
+
+## B) App and Deployment
+- [ ] Dokploy project connected to Gitea repo.
+- [ ] Secrets configured:
+  - [ ] `DATABASE_URL`
+  - [ ] `DATABASE_SSL`
+  - [ ] `ALLOWED_DB_NAMES`
+  - [ ] `SESSION_COOKIE_NAME`
+  - [ ] `SESSION_TTL_DAYS`
+  - [ ] `DEBUG_API=0`
+  - [ ] `DOKPLOY_DEPLOY_HOOK`
+  - [ ] `DOKPLOY_HEALTHCHECK_URL`
+- [ ] Deploy workflow passes build/test/push/deploy.
+- [ ] Post-deploy health gate passes (`scripts/wait-for-health.sh`).
+- [ ] Manual smoke passes (`scripts/smoke-public-launch.sh`).
+
+## C) Security Controls
+- [ ] Nginx TLS/headers/rate limits enabled (`docker/nginx/fiddy.conf`).
+- [ ] Request-id propagation enabled (`X-Request-Id` in responses).
+- [ ] Server-side rate limits active (auth/write/ip limiters).
+- [ ] Fail2ban or CrowdSec configured from `docker/security/`.
+- [ ] No secrets/full invite codes in logs.
+
+## D) Observability
+- [ ] Loki, Promtail, Grafana, Uptime Kuma running.
+- [ ] Promtail ingests `job="nginx"`.
+- [ ] Dashboards show request IDs for incident triage.
+- [ ] Alerts configured for 5xx/auth spikes/DB failures/resource pressure.
+
+## E) Backup and Recovery
+- [ ] Daily logical backup scheduled (`scripts/backup-postgres.sh`).
+- [ ] Periodic base backup scheduled (`scripts/basebackup-postgres.sh`).
+- [ ] Latest restore drill succeeded (`scripts/restore-drill-postgres.sh`).
+- [ ] Drill logged (`scripts/log-restore-drill.sh` -> `docs/restore-drill-log.csv`).
+- [ ] Measured RTO is acceptable.
+
+## F) Rollback Readiness
+- [ ] Previous stable release retained in Dokploy.
+- [ ] Rollback runbook tested once in staging or low-risk window.
+- [ ] Rollback smoke check verified.

 - Retention:
