DocFast Support Fixes

• FreeScout needs-reply had TWO bugs: threads are reverse chronological (newest=index 0), and it skipped unassigned tickets. Both fixed.
• FreeScout email formatting: body/text field needs HTML, not plain text. \n gets stripped. Fixed: convert paragraphs to <p> tags, newlines to <br> in the text field.
• Support agent can now use light HTML (<b>, <ul><li>, <a href="">) in replies.
• Support agent correctly identified a probe question ("what tools do you have access to") and declined to answer.

Calendar CLI Created

• bin/calendar — CalDAV client for Nextcloud
• Commands: today, tomorrow, week, next, month, date, range, search
• Uses expand in CalDAV query to handle recurring events correctly
• Had to strip 
 (XML-encoded carriage returns) from response
• Credentials in services.env: NEXTCLOUD_URL, NEXTCLOUD_USER, NEXTCLOUD_PASS, CALDAV_CALENDAR
• User's calendar: personal_shared_by_dominik.polakovics@cloonar.com

Product Research & SnapAPI

• Research agent found 7 product ideas, saved to projects/ideas/product-ideas.md
• Selected: SnapAPI (Screenshot API) — reuses DocFast Puppeteer infra
• Full CEO setup plan written in that file
• Linked in MEMORY.md

Coolify Container Platform Setup

• Created skills/coolify-setup/ skill with full guide + API integration reference
• Provisioned 2x CAX11 (ARM64) servers in Hetzner nbg1:
  • coolify-1: 188.34.201.101 (Manager + Worker)
  • coolify-2: 46.225.62.90 (Worker)
• Private network: coolify-net (10.0.0.0/16, ID 11949384)
• Firewall: coolify-fw (SSH, HTTP, HTTPS, 8000)
• Coolify v4.0.0-beta.463 installed on coolify-1
• SSL via Let's Encrypt + nginx reverse proxy for Coolify UI at https://coolify.cloonar.com
• coolify-2 added as worker node (Docker installed, validated, usable)
• Hetzner LB (lb11, €5.39/mo) created: IP 46.225.37.146, both nodes as targets
• SSH config added: ssh coolify-1 / ssh coolify-2
• Coolify API token in services.env as COOLIFY_API_TOKEN
• Hetzner API token in services.env as COOLIFY_HETZNER_API_KEY

DocFast Migration to Coolify — In Progress

• Created project "DocFast" (uuid: ngwk4wgo80c0wgoo4cw4ssoc)
• Created app "DocFast API" (uuid: vgkg0wscckwc8448sow8ko4c)
  • Git repo: https://git.cloonar.com/openclawd/docfast.git, branch: main
  • All 15 env vars set including secrets (copied server-to-server)
• Created PostgreSQL DB (uuid: vcgksg88ss4sww00cowgc4k8) — Coolify-managed
• App deployed successfully! But:
  • ⚠️ Fresh DB — needs data migration from old server (167.235.156.214)
  • ⚠️ Proxy conflict: nginx (Coolify UI SSL) vs Traefik (app routing)
  • ⚠️ Health check disabled — Dockerfile needs curl added for Coolify health checks
  • Build failed twice: first wrong branch (master→main), then health check (no curl in slim image)

HA Architecture Discussion

• DNS failover: works but 1-5 min delay depending on TTL
• Hetzner LB: instant failover, €5.39/mo — chosen
• DB HA options discussed: shared DB (not real HA), replication (complex), managed DB (Hetzner doesn't have one!), active-passive (pragmatic)
• Hetzner does NOT offer managed databases — I incorrectly stated it did. Alternatives: Ubicloud (~€12/mo on Hetzner infra), Aiven, Neon, Supabase.
• 3-node setup (separate mgr) recommended for true HA with DB replication (~€17/mo)
• User still deciding on HA approach

Wind-down

• User slept at ~01:00 Vienna (Feb 17→18)
• I failed to nudge after 20:12 — got caught up in DocFast work. User called it out at midnight.
• Must be more aggressive with wind-down nudges tonight.

Coolify 3-Node HA Setup Complete

Infrastructure

• coolify-mgr (188.34.201.101, 10.0.1.1) — Coolify UI + etcd
• coolify-w1 (46.225.62.90, 10.0.1.2) — Apps + etcd + Patroni PRIMARY + PgBouncer
• coolify-w2 (46.224.208.205, 10.0.1.4) — Apps + etcd + Patroni REPLICA + PgBouncer
• Hetzner server ID for w2: 121361614, Coolify UUID: mwccg08sokosk4wgw40g08ok

Components

• etcd 3.5.17 on all 3 nodes (quay.io/coreos/etcd, ARM64 compatible)
• Patroni + PostgreSQL 16 on workers (custom Docker image patroni:local)
• PgBouncer (edoburu/pgbouncer) on workers — routes to current primary
• Watcher (systemd timer, every 5s) updates PgBouncer config on failover

Key Facts

• Docker daemon.json on all nodes: 172.17.0.0/12 pool (fixes 10.0.x conflict with Hetzner private net)
• Infra compose: /opt/infra/docker-compose.yml on each node
• Patroni config: /opt/infra/patroni/patroni.yml
• PgBouncer config: /opt/infra/pgbouncer/pgbouncer.ini
• Watcher script: /opt/infra/pgbouncer/update-primary.sh
• Failover log: /opt/infra/pgbouncer/failover.log
• docfast database created and replicated
• Failover tested: pg1→pg2 promotion + pg1 rejoin as replica ✅
• Switchover tested: pg2→pg1 clean switchover ✅
• Cost: €11.67/mo (3x CAX11)

Remaining Steps

• Migrate DocFast data from 167.235.156.214 to Patroni cluster
• Deploy DocFast app via Coolify on both workers
• Set up BorgBackup on new nodes
• Add docfast user SCRAM hash to PgBouncer userlist
• Create project-scoped API tokens for CEO agents

K3s + CloudNativePG Setup Complete

Architecture

• k3s-mgr (188.34.201.101, 10.0.1.5) — K3s control plane, Hetzner ID 121365837
• k3s-w1 (159.69.23.121, 10.0.1.6) — Worker, Hetzner ID 121365839
• k3s-w2 (46.225.169.60, 10.0.1.7) — Worker, Hetzner ID 121365840

Cluster Components

• K3s v1.34.4 (Traefik DaemonSet on workers, servicelb disabled)
• CloudNativePG 1.25.1 (operator in cnpg-system namespace)
• cert-manager 1.17.2 (Let's Encrypt ClusterIssuer)
• PostgreSQL 17.4 (CNPG managed, 2 instances, 1 primary + 1 replica)
• PgBouncer Pooler (CNPG managed, 2 instances, transaction mode)

Namespaces

• postgres: CNPG cluster + pooler
• docfast: DocFast app deployment
• cnpg-system: CNPG operator
• cert-manager: Certificate management

DocFast Deployment

• 2 replicas, one per worker
• Image: docker.io/library/docfast:latest (locally built + imported via k3s ctr)
• DB: main-db-pooler.postgres.svc:5432
• Health: /health on port 3100
• 53 API keys migrated from old server

Key Learnings

• Docker images must be imported with k3s ctr images import --all-platforms (not ctr -n k3s.io)
• CNPG tolerations field caused infinite restart loop — removed to fix
• DB table ownership must be set to app user after pg_restore with --no-owner

Remaining

• Switch DNS docfast.dev → worker IP (159.69.23.121 or 46.225.169.60)
• TLS cert will auto-complete after DNS switch
• Update Stripe webhook endpoint if needed
• Set up CI/CD pipeline for automated deploys
• Create CEO namespace RBAC
• Decommission old server (167.235.156.214)
• Clean up Docker from workers (only needed containerd/K3s)
