# Session Resume

Last updated: 2026-05-22. Update this at the end of every session.

## Open items (urgency order)

### 🔴 Critical — security risk or unrecoverable data loss
- [ ] **Password rotation: `tapirnase`** — shared across WiFi PSK, LiteLLM root key (`sk-tapirnase`), D-Link admin, Backrest repo password. Single sniff = broad blast radius. Rotate per-service. See `services/homelab-architecture.md` §operational rules.
- [ ] **UNAS personal data off-host** — ~820 GB Immich library + UNAS bulk have zero off-host copy. Deploy rclone sync: `media/images/library` → jottacloud:Photos + full UNAS → jottacloud:UNAS. See `services/backrest.md` phase 1a.
- [ ] **Nextcloud Borg passphrase → Vaultwarden** — passphrase only in container env; CT 105 loss = unrecoverable backup. Move to Vaultwarden. See `services/backrest.md` blind spot #4b.

### 🟠 High — known broken / verification needed
- [ ] **Arcane OIDC secret** — rotation done 2026-05-22 but Arcane has known OIDC issues. Verify it still authenticates.
- [ ] **Backrest media-repo** — `video-projects-plan` and `media-backup-plan` were at 0 snapshots as of 2026-05-22 19:10. Verify snapshots landed.
- [ ] **AdGuard split-horizon DNS** — internal clients still resolve to public IPs. Rewrite rules audit. See `services/adguard-dns.md`.
- [ ] **WAL-G monitoring** — silent stall went undetected for 13 h. Add textfile collector + alert for hung archiver. See `services/homelab-architecture.md` roadmap.
- [ ] **Zoraxy audit** — CT 108 routes: WS headers, ACME coverage, decommissioned routes, auth consistency. See `services/zoraxy.md`.

### 🟡 Medium — incomplete migrations / cleanup debt
- [ ] **Docker disk reclaim** — ~17 GB reclaimable on CT 104 (10.3 GB unused images, 6.9 GB build cache). `docker system prune -a` after confirming no needed images. See `infra/proxmox-state.md` §10c.
- [ ] **Dormant stacks audit** — ~10 stacks defined but not running (homepage, dozzle, arr-stack, qdrant, etc.). Document: parked vs. abandoned. See `infra/proxmox-state.md` §10c.
- [ ] **Config-to-git** — push zoraxy, adguard, pve, ha configs daily to Gitea repos (repos exist, cron not deployed). See `services/backrest.md` phase 3.
- [ ] **D-Link hardening** — admin UI open to full LAN, SNMP unverified, HTTP-only. Enable trusted-host allowlist, harden SNMP, add TLS. See `services/homelab-architecture.md`.
- [ ] **Vaultwarden OIDC SSO** — Pocket-ID client created 2026-05-21, auth flow not wired up.

### 🔵 Planned — requires infrastructure or significant effort
- [ ] **CT 109 "ops"** — LXC for Prometheus, Loki, Grafana, Alloy, Homarr, sshwifty, Gotify. Blocks monitoring stack + Arcane migration. See `infra/proxmox-state.md` §16.
- [ ] **Second NVMe** — needed before rpool mirror + Postgres consolidation (CT 113). Blocks several items.
- [ ] **Infisical secrets migration** — CT 112 provisioned; migration not started. Phase 1-4: move 85+ `.env` keys. See `services/secrets-manager.md`.
- [ ] **Consolidate syncstack → MCP gateway** — move LiteLLM model polling + LobeChat sync into gateway's loop; delete syncstack cron.
- [ ] **ZFS ARC tuning** — raise `zfs_arc_max` from 6.2 GiB → 16 GiB once CT 101 memory right-sized. See `infra/proxmox-state.md` §3.
- [ ] **Document ingestion n8n workflow** — Docling MCP deployed; n8n orchestration not built. Nextcloud/Paperless → Docling → embeddings → LobeChat KB. See `services/doc-ingestion.md`.
- [ ] **ComfyUI async queue** — MCP tool blocks 90–300 s. Job-queue pattern: `generate_image()` returns ID; `get_job_status()` polls. See `services/comfyui.md`.
- [ ] **Additional MCP servers** — community MCPs exist for Gitea, Paperless, Karakeep, Vaultwarden, Proxmox-VE, Audiobookshelf. Evaluate + wire in.
- [ ] **Arcane → CT 109 migration** — blocked by CT 109. Procedure documented in `services/arcane.md`.
- [x] ~~**crawl4ai SSE StreamConsumed**~~ — resolved 2026-05-22. Errors were from old code in log history; clean restart confirms no errors. Health: ok (7 tools), lobe-sync: 27/27 servers.

## 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.
