+### 2026-06-24 Sprint Day 5 facts
+- id=141 COMPLETE ✅ — Full Jenkins E2E verified: Build → Push → Sandbox Deploy → Smoke Test all pass (build #9)
+- Dockerfile fix: replaced docker.io with docker-ce-cli via Docker official apt repo (docker.io on Debian Trixie does NOT install docker binary); rebuilt with --no-cache
+- Jenkinsfile fixes required across multiple iterations:
+  - gitea-credentials (usernamePassword) used for docker login — not secrets-proxy /secret (endpoint doesn't exist)
+  - Compound commands (&&, cd, $()) don't work — sudo-bridge uses subprocess.run(shlex.split()) with no shell; must use separate bridge calls
+  - readJSON step not available — pipeline-utility-steps plugin not installed; replaced with python3 shell parsing
+- plugins.txt: pipeline-utility-steps added (takes effect on next Jenkins image rebuild)
+- server-01 allowlist.json: root:root + chmod 644 ownership (requires manual sudo to update — bootstrap problem)
+  - New patterns added: docker pull *, docker compose -f * up -d, docker inspect --format=* *, docker ps *
+- Promote to Production stage still uses compound command via secrets-proxy /shell — exits non-zero but Jenkins reports SUCCESS (fix deferred)
+- Coolify API evaluation: Jenkins handles all deploy work; N8N env var rotation workflows still use Coolify API — will need migration when Coolify retires
+- personal_projects id=147: coolify-traefik-retirement (p1), id=148: pam-ntfy-fingerprint-sudo (p3)
+- New universal rules: feedback_evaluate_jenkins_hermes_fit.md (Jenkins/Hermes fit check on every automation design + background audit once both deployed)
+- Hermes exploration day memory added: schedule full day after id=138 deploys before adding more Hermes-dependent tasks
+- SSH sudo requires TTY — bridge bootstrap problem: allowlist.json is root-owned, must use manual sudo once to update it
+
+**Next session first task:** Coolify + standalone Traefik retirement (personal_projects id=147)
+- Read legacy-docker-compose/traefik/ files in boilerplates (starting point)
+- Audit current coolify-proxy config on primary + server-01
+- Build standalone Traefik configs for both servers
+- Swap traffic, verify all routes, retire Coolify
