Open items (priority order)

Backup gaps

• Pocket-ID backup — done 2026-05-22. Pre-hook on CT 103 exports via pocket-id export + copies keys to UNAS staging; services-backup-plan → jottacloud. Verified snapshot includes Pocket-ID data.
• Backrest media-repo — video-projects-plan and media-backup-plan were at 0 snapshots but both restic processes were actively running as of 2026-05-22 19:10. Verify snapshots landed after they complete.
• Gitea repos — already in services-backup-plan → jottacloud. DB on CT 113 (WAL-G).
• Coder workspace homes — already in services-backup-plan → jottacloud.

Infrastructure

• CT 109 "ops" — planned LXC for Prometheus, Loki, Grafana, Alloy, Homarr, sshwifty, Gotify. Not yet built. See infra/proxmox-state.md §16.
• Second NVMe — needed before Postgres consolidation (CT 113) and rpool mirror. Unblocks moving remaining per-stack PG containers to CT 113.
• Vaultwarden NFS cleanup — /mnt/pve/unas/services/vaultwarden/ deleted 2026-05-22.
• apps/backrest rename — done 2026-05-22 (renamed from PVE host via ZFS subvolume path; idmapped LXC blocked it from inside CT 104).

MCP / AI stack

• Consolidate syncstack → MCP gateway — syncstack.py cron is fragile; move LiteLLM model polling + LobeChat model-list sync into mcp-gateway/server.py alongside the existing plugin sync loop. Delete syncstack container + cron after.
• crawl4ai SSE StreamConsumed — intermittent 502s on first request after gateway restart (race with in-flight requests from old code). Investigate if still present after a clean restart cycle; likely harmless but worth confirming.

Audits / housekeeping

• Zoraxy audit — CT 108 routes: WS headers, ACME coverage, decommissioned routes, auth consistency (Tinyauth gaps). See services/zoraxy.md.
• Arcane OIDC secret — rotation was done 2026-05-22 but Arcane has known issues with OIDC. Verify it still authenticates cleanly.
• AdGuard split-horizon DNS — some internal services still resolve to public IPs instead of LAN IPs for internal clients. Needs rewrite rules audit in services/adguard-dns.md.

Recently completed (session continued ×2, 2026-05-22)

• crawl4ai MCP fixed: was returning 404 on /mcp (streamable-HTTP). Current 0.8.6 image already has MCP over SSE at /mcp/sse. Added SSE transport support to mcp-gateway/server.py: per-request SSE round-trip with auto-initialize handshake; transport: sse in hardcoded SERVERS + config.json. Gateway health now shows crawl4ai ok; lobe-sync shows 27/27 servers.
• syncstack cron fixed: missing cd /opt/stacks/ai && prefix caused "no configuration file" every 15 min since ~May 18. Fixed. Manual run confirmed 60 models including 5 Claude models; LobeChat recreated.

Recently completed (session continued, 2026-05-22)

• claude-max-bridge /v1/responses endpoint: implemented OpenAI Responses API with previous_response_id chaining. Root cause of "session already in use": Claude CLI leaves session JSONL files in an un-resumable "dequeued" state after each --print run. Fix: maintain conversation history server-side as formatted text; inject into system prompt for continuations; always use --no-session-persistence. Also fixed: assistant turns in --input-format stream-json require content as array-of-blocks not string (JS error otherwise). Assistant content array format also fixed in _parse_messages / _parse_responses_input.
• LiteLLM pass-through for /v1/responses: added pass_through_endpoints entry in /opt/stacks/ai/litellm-config/config.yaml → http://claude-max-bridge:8000/v1/responses. LiteLLM appends its token hash to the response id, so previous_response_id chaining only works when calling the bridge directly (not through LiteLLM).

Recently completed (this session, 2026-05-22)

• Pocket-ID backup: pre-hook on CT 103 runs pocket-id export + scp keys → UNAS staging; services-backup-plan snapshots → jottacloud. Verified.
• Stale NFS vaultwarden dir deleted: /mnt/pve/unas/services/vaultwarden/ removed.
• Nextcloud CIFS → NFS: crash-loop fixed; CT 105 mp0 migrated from /mnt/pve/unas_smb to /mnt/pve/unas; CIFS fstab entry removed.
• Vaultwarden → local zfs: /mnt/pve/unas/services/vaultwarden → /opt/stacks/vaultwarden/data; stale db.sqlite3 deleted; DB already on CT 113 postgres.
• WAL-G fixed: immich_postgres and lobe-postgres backups now succeed. Fixed: missing -u postgres, missing data path, set -e abort, dead shared-postgres reference.
• ComfyUI --async-offload removed: caused CPU fallback + pure-noise output on GGUF img2img with XPU.
• apps/ decommissioned: dead duplicate compose files in /opt/stacks/apps/ renamed .DECOMMISSIONED-2026-05-22.
• Docs consolidated: storage.md, volumes.md, homelab-architecture.md, proxmox-state.md, proxmox-memory-audit.md, ct-inventory.md, README.md all reconciled.

Key system state

Host	IP	Role
nuc (PVE)	192.168.1.20	Proxmox host — SSH gateway to all CTs
CT 104 docker	192.168.1.40	Main Docker host — AI/ML, media, ~65 containers
CT 113 db	192.168.1.6	Shared Postgres 17 + WAL-G → Garage S3 (cron 02:00)
CT 110 id	192.168.1.5	Pocket-ID OIDC IdP
CT 103 backrest	192.168.1.3	Backrest — jottacloud via rclone; UNAS at /mnt/pve/unas
CT 111 dev	192.168.1.42	Coder + Gitea
CT 108 zoraxy	192.168.1.4	Reverse proxy + ACME — always confirm before changes

Constraints to remember

• Zoraxy (CT 108): always get explicit user confirmation before any config change.
• Infisical (CT 112): LAN-only, no Zoraxy route — must not be internet-exposed.
• CT 104 has a separate agent reconciling compose files — rename decommissioned files (don't just stop), update /opt/stacks/CLAUDE.md.
• ComfyUI container limit: 24 G. Do not raise without measuring host impact.
• Pocket-ID is SQLite-only — no Postgres migration possible.
