See /CLAUDE.md for the full doctrine. Highlights: 1. Keep services running; surface synergies and gaps. 2. Enforce consistency: Pocket-ID OIDC, Zoraxy + ACME, <svc>.nuclide.systems, secrets in .env. 3. Plan rollback at medium+ risk (ZFS snapshots, fresh experimental CTs). 4. Every service should be AI-accessible (MCP / Coder workspace CLI / documented API). 5. Test end-to-end before declaring done. 6. Generate slash commands for recurring maintenance.

"},{"location":"ideas/litellm-claude-max-bridge/","title":"Design: Claude Max Subscription \u2192 LiteLLM Gateway Bridge","text":"

Status: Proposal \u2014 not implemented Context: LiteLLM at https://ai.nuclide.systems currently has no Anthropic models. Claude Max subscription (claude.ai) provides high-rate access to Sonnet 4.5/4.6 and Opus 4.7 but is decoupled from Anthropic API billing. This doc explores bridging the two.

"},{"location":"ideas/litellm-claude-max-bridge/#problem","title":"Problem","text":"

Claude Max and the Anthropic API are separate products with separate billing:

Claude Max Anthropic API Auth OAuth / browser session API key Billing Flat monthly subscription Per-token Rate limits 5h rolling windows, model-specific Tier-based RPM/TPM Access claude.ai web + Claude Code CLI Any HTTP client

The goal is to surface Max-subscription capacity through LiteLLM so that LobeHub, n8n, Coder workspaces, and other internal tools can call claude-sonnet-4-6 at zero marginal cost and fall back to paid providers only when Max limits are hit.

Several community projects (e.g. claude-unofficial-api) scrape the claude.ai WebSocket/HTTP protocol and expose an OpenAI-compatible endpoint. LiteLLM would point at this as a custom openai/ provider.

Pros: Exposes the full web model lineup; streaming works. Cons: Violates Anthropic ToS; breaks on any claude.ai front-end change; auth flow requires persisting browser cookies; no multimodal or tool-use parity guarantees.

Verdict: Avoid. Fragile and non-compliant.

"},{"location":"ideas/litellm-claude-max-bridge/#b-claude-code-cli-bridge-recommended","title":"B \u2014 Claude Code CLI Bridge (recommended)","text":"

Claude Code CLI (claude) is already installed on CT 104 and authenticated with the Max subscription via ~/.claude/. It ships a --print / --output-format stream-json mode designed for non-interactive use, and Anthropic explicitly supports programmatic use of the CLI.

A small claude-max-bridge service wraps this CLI as an OpenAI-compatible HTTP endpoint. LiteLLM registers it as a custom openai/ base URL. No ToS issues \u2014 this is the supported surface.

LobeHub / n8n / Coder / Claude Code\n          \u2502\n          \u25bc\n    LiteLLM Gateway  (ai.nuclide.systems)\n          \u2502  model: claude-sonnet-4-6  \u2192  openai/claude-sonnet-4-6\n          \u2502  api_base: http://claude-max-bridge:8000\n          \u25bc\n    claude-max-bridge  (new container, CT 104 ai-internal)\n          \u2502  subprocess:  claude --model ... --print --output-format stream-json\n          \u25bc\n    ~/.claude/  (Max subscription session)\n          \u2502\n          \u25bc\n    Anthropic (claude.ai)\n

Pros: - Uses the officially supported programmatic interface - Auth is already set up; no cookie management - claude CLI handles retries, token limits, context window management - Subprocess overhead is ~200\u2013400 ms cold; warm invocations faster

Cons: - One subprocess per request \u2014 cannot multiplex a single session (unlike streaming HTTP) - CLI is tied to the single authenticated user; no multi-user isolation - Max rate limits apply per-account, same pool as interactive use - Claude Code SDK (TypeScript) is cleaner but adds Node dependency

"},{"location":"ideas/litellm-claude-max-bridge/#c-official-api-budget-cap-stop-gap","title":"C \u2014 Official API + Budget Cap (stop-gap)","text":"

Add Anthropic API key to LiteLLM with a hard budget cap (e.g. $20/month). Use it for Claude-specific features (tool use, long context) and let the existing free SAIA/Gemini fallback chain absorb general-purpose traffic.

Pros: Zero implementation work; full API feature parity. Cons: Still costs money; no benefit from Max subscription.

Verdict: Valid fallback if B proves too complex, or as a complement for tool-heavy workloads that need the official API surface.

Goal: ingest PDFs, Word, PPT, XLS \u2192 searchable in LobeChat chat + accessible via MCP. Qdrant is a nice-to-have, not a requirement (no live pipeline uses it yet).

LobeChat already has a built-in knowledge base (knowledge_base_files, chunks, embeddings tables in Postgres). The missing piece is an ingest pipeline that feeds it.

Recommended architecture: 

Nextcloud folder / Paperless webhook\n  \u2192 n8n trigger (already running)\n  \u2192 Docling (PDF/DOCX/PPTX/XLSX \u2192 Markdown + structure)\n  \u2192 LiteLLM /v1/embeddings (Mistral-embed / codestral-embed)\n  \u2192 LobeChat knowledge base API  \u2190\u2014 available in chat natively\n  \u2192 Qdrant sidecar (optional, if multi-app search needed)\n

Document conversion options:

Tool Docker image Formats NUC 14 CPU fit Docling (IBM, 2024) ghcr.io/ds4sd/docling PDF, DOCX, PPTX, XLSX, HTML, Markdown \u2705 CPU-only, 10-60s/doc MinerU (OpenDataLab) opendatalab/mineru PDF (layout-aware, OCR) \u2705 CPU mode; GPU optional for speed Unstructured quay.io/unstructured-io/unstructured-api Very broad (25+ formats) \u2705 lighter than Docling Markitdown (already in MCP gateway) \u2014 Office + PDFs \u2192 Markdown \u2705 ad-hoc only, not batch

Docling vs MinerU: Docling is better for structured Office/PDF with tables and figures. MinerU (OpenDataLab) is better for pure PDF optical layout analysis (e.g., academic papers, scanned documents). Both run on NUC 14 CPU. Start with Docling \u2014 single container, REST API, well-documented.

MCP access: add a knowledge-search MCP tool to the gateway that calls LobeChat's knowledge base search API. Zero new infra \u2014 LobeChat is already on shared_backend.

IBM Granite embedding (granite-embedding-30m-english) \u2014 good quality, tiny (30M params), runs CPU-only. Alternative to Mistral-embed if you want fully local embeddings. Not on LiteLLM yet but can add as a custom provider pointing at an Ollama/IPEX-LLM instance.

"},{"location":"ideas/stack-ideas/#2-document-conversion-pipeline","title":"2. Document conversion pipeline","text":"

Problem: No systematic ingestion path from raw docs (PDF, DOCX, HTML) into structured text for chunking/embedding.

Tools to consider:

Tool Docker image Best for Docling (IBM, 2024) ghcr.io/ds4sd/docling PDFs with complex layout (tables, columns, figures); outputs Markdown Unstructured quay.io/unstructured-io/unstructured-api Wide format support (HTML, DOCX, PPTX, images with OCR); REST API Gotenberg gotenberg/gotenberg HTML/Office \u2192 PDF pre-processing stage; not a text extractor Apache Tika apache/tika Broad format support; outputs plain text; lower quality than Docling for PDFs Markitdown MCP already in gateway Ad-hoc on-demand conversion; not suitable for batch pipelines

Nextcloud / Paperless webhook\n  \u2192 Gotenberg (Office \u2192 PDF)\n  \u2192 Docling (PDF \u2192 Markdown chunks)\n  \u2192 LiteLLM /v1/embeddings (Mistral-embed)\n  \u2192 Qdrant upsert\n

Docling runs CPU-only comfortably on the NUC. Unstructured is heavier but has a managed API if the self-hosted version is too slow.

Paperless-ngx already OCRs documents \u2014 its full-text content is accessible via the REST API. An n8n workflow polling /api/documents/?added__gt=<last_run> can extract and re-embed directly, without re-running OCR.

Current problem: MCP tool blocks until the image is done (~90-290s). LLMs time out at ~60s. The fix is a job-queue pattern:

Question: build an adapter in LiteLLM to use models via \"quasi API\" (non-standard endpoints, auth, or routing)?

LiteLLM supports custom providers via custom_llm_provider in config.yaml. You write a Python class that implements completion() and async_completion(). This is the right path for wrapping non-standard APIs (local models, proprietary endpoints, protocol bridges).

Example use cases: - Wrap a Claude Max subscription via Anthropic's API (different billing model) - Add a local model served by IPEX-LLM on the Arc iGPU - Bridge a custom inference server that speaks a different protocol

LobeChat provider extension: LobeChat's provider list is compiled into the app. Adding a new provider requires rebuilding LobeChat from source (fork + add to src/config/aiModels/). High effort; only worth it for a permanent/long-term provider. For ad-hoc needs, use LiteLLM as the adapter and point LobeChat at it via the existing ai.nuclide.systems OpenAI-compatible endpoint.

Setting ComfyUI's container limit to 40 G was the trigger.

ComfyUI's get_free_memory() for Intel XPU queries torch.xpu.get_device_properties().total_memory = 58 GB (the full shared memory pool \u2014 Arc shares system RAM). It has no awareness of the Docker cgroup limit. Smart memory management (free_memory()) calculates memory_required - get_free_memory() which is always hugely negative \u2192 never evicts models. This makes --disable-smart-memory irrelevant for XPU; smart memory is already broken.

Consequence: ComfyUI will always try to load the full model into XPU memory regardless of container limit. The cgroup OOM killer is the only backstop.

  1. ComfyUI container limit: set to 24 G when running without --lowvram. Current revert to 20 G + --lowvram is stable but slower.
  2. CT 104 LXC allocation (49 GiB): appropriately sized given Docker workload, but is by far the largest single consumer. Do not raise further without measuring host impact.
  3. CT 111 (dev, 32 GiB): Coder workspaces could spike if users run heavy jobs. Consider adding a per-workspace memory limit in the Coder template.
  4. Watch list: CT 101 (Shepard, 32 GiB) + CT 104 simultaneously at peak = 54 GB \u2192 host would need to swap. Unlikely in practice but possible during CI runs on CT 111 + FLUX generation on CT 104.

Backend: 192.168.1.31 (looks like a UniFi NAS \u2014 exports /volume/.../.unifi-drive/storage/.data, the only NFS export listed is restricted to four allowed clients: the host .20, CT 104 .40, plus .60 and 172.30.33.1).

Two parallel mounts on the host pointed at the same backing data:

Mount Type Options (key bits) Consumers /mnt/pve/unas NFS v3 proto=tcp, mountproto=udp, rsize/wsize=1M, hard, relatime, timeo=600 CT 103 (backrest), CT 104 (docker) \u2014 bind-mounted to /mnt/pve/unas inside /mnt/pve/unas_smb CIFS v3.1.1 cache=strict, actimeo=1, soft, rsize/wsize=4M, uid/gid=33 CT 105 (nextcloud) \u2014 bind-mounted to /mnt/pve/unas inside

Issues:

  1. CT 105 is on CIFS to the same data CT 104 uses via NFS. Pure duplication. Nextcloud does massive amounts of stat() traffic; actimeo=1 on the CIFS mount forces every metadata lookup to hit the wire, which is slow.
  2. NFS is v3, not v4.x. v4 is preferred unless the UDM doesn't export it. v4 fixes locking, removes the separate mountd dance, and supports session trunking.
  3. mountproto=udp under packet loss can intermittently fail to (re)mount. Set mountproto=tcp.
  4. hard mount with no intr equivalent. If UNAS goes away, anything blocked on it hangs the calling process indefinitely. For non-critical use cases (Nextcloud, but not backrest), soft,timeo=100,retrans=3 is friendlier \u2014 Backrest backups should stay hard.
  5. CT 105 cannot mount NFS directly because the UNAS export only allows IPs .20/.40/.60/.172.30.33.1 \u2014 .41 (CT 105) is missing. So either keep the host-side bind-mount approach (correct) or have UNAS export to .41 too.
  6. The bind-mount approach is correct for unprivileged CTs that can't run NFS/CIFS clients themselves. Don't change that pattern.

Recommended consolidation:

# 1. Probe whether the NAS speaks NFSv4\nmount -t nfs -o vers=4.2,proto=tcp 192.168.1.31:/var/nfs/shared/storage /mnt/test\n# if it works:\npvesm set unas --options vers=4.2,proto=tcp,hard,noatime\n# (this re-mounts on next access; or unmount/remount /mnt/pve/unas)\n\n# 2. Switch CT 105 to the NFS bind-mount\npct set 105 --mp0 /mnt/pve/unas,mp=/mnt/pve/unas\n# (CT 105 currently uses unas_smb \u2192 unas. New line bind-mounts the NFS mount.)\n# Then verify nextcloud-aio still sees uid/gid 33 properly \u2014 NFS uses host UIDs,\n# whereas CIFS was forcing uid=33. May need to chown on the NAS or add an idmap.\n\n# 3. Drop the CIFS storage once CT 105 is migrated\npvesm remove unas_smb   # if it exists as PVE storage\n# or remove the entry from /etc/pve/storage.cfg\n

CT 104 keeps its Docker workloads in a git-tracked monorepo at /opt/stacks/ with one directory per stack, plus meta-docs (PORTMAP.md, storage.md, volumes.md, docker-networks.md, todo.md). Good practice \u2014 this is how to keep ~65 containers manageable. The other CTs (101, 105) don't have /opt/stacks \u2014 their compose files live elsewhere.

Stack list (29 dirs):

Observations:

  1. ~10 stacks are defined but dormant. No RAM/CPU cost while down, but their images sit on disk and the git repo accrues dead code. Either run them, document why they're parked, or git rm them \u2014 repo drift is the silent killer of \"I know what's running\" confidence.
  2. Stack name \u2260 compose project name for the ai/ and daytona/ trees (multiple compose files per dir, different project names). The syncstack.py helper exists for this; just be aware that docker compose -f lookups by directory name don't match.
  3. Disk-reclaim potential (measured docker system df):

~13 GB to recover. On a 200 GB rootfs that's 64 % full, this is meaningful.

  1. Stack\u2192Zoraxy mapping (\u00a711b): when fronting via Zoraxy, the canonical service endpoints (per PORTMAP.md) are CT 104's IP 192.168.1.40 + port. Worth cross-referencing that file when setting up reverse-proxy entries.

Current state: the PVE web UI on https://192.168.1.20:8006 uses the self-signed certificate generated at install (/etc/pve/local/pveproxy-ssl.pem is absent \u2192 falls back to pve-ssl.pem). Every login throws a browser warning.

The wider setup: Zoraxy (CT 108, 192.168.1.4) already handles Let's Encrypt for nuclide.systems (the public domain for this host). So there are three sane options; pick A unless you have a reason not to.

"},{"location":"infra/proxmox-state/#option-a-reverse-proxy-pve-through-zoraxy-recommended","title":"Option A \u2014 Reverse-proxy PVE through Zoraxy (recommended)","text":"

Pros: single source of LE truth (Zoraxy already renews); no DNS-plugin setup; no exposing the API; nice domain like pve.nuclide.systems. Cons: depends on Zoraxy being up (keep IP:8006 as fallback); needs WebSocket pass-through for the noVNC console and xterm.js shell.

  1. Zoraxy host entry
  2. Domain: pve.nuclide.systems (or whatever subdomain)
  3. Target: https://192.168.1.20:8006
  4. Enable WebSocket support (mandatory \u2014 noVNC, xterm.js, task log streaming all use it)
  5. Skip backend TLS verification (PVE's cert is self-signed)
  6. Enable HSTS once you've confirmed the setup works
  7. Optionally restrict by source: only LAN + Cloudflare/Tailscale IPs
  8. DNS: add an A record pve.nuclide.systems \u2192 public IP (or split-horizon to 192.168.1.20 for LAN). Zoraxy will ACME-challenge via whichever method it's configured for (HTTP-01 or DNS-01).
  9. Keep https://192.168.1.20:8006 reachable on LAN as an emergency fallback. Don't disable it.
  10. Set the PVE redirect-to-HTTPS rules in Zoraxy on for both :80 and :443.

Important caveat: the PVE Mobile app and the pvesh / API clients may not love going through a reverse proxy (they're picky about TLS SNI and cookie domains). Keep direct IP access available for API tooling, or test thoroughly.

Pros: no reverse proxy in the path; PVE renews itself; works for the API too. Cons: requires a DNS provider plugin (your registrar's API token), and an LE-acceptable FQDN that resolves publicly.

  1. Register an ACME account: 
    pvenode acme account register default you@nuclide.systems\n
  2. Configure a DNS plugin. PVE supports acme-dns, cloudflare, route53, desec, etc. via the acme.sh plugin set. Example for Cloudflare: 
    pvenode acme plugin add dns cf --api cf --data CF_Token=XXXXXXXX\n
    Replace cf plugin name to match whichever registrar you use for nuclide.systems.
  3. Tell the node which domain(s) and how: 
    pvenode config set --acme domains=nuc.nuclide.systems\npvenode config set --acmedomain0 domain=nuc.nuclide.systems,plugin=cf\n
  4. Order: 
    pvenode acme cert order\n
    PVE drops the cert at /etc/pve/nodes/nuc/pveproxy-ssl.pem and renews ~30 days before expiry via the pve-daily-update timer.

Only useful if A and B are off the table. Zoraxy stores its issued certs (location varies by Zoraxy version \u2014 typically under its data dir, e.g. /opt/zoraxy/conf/certs/).

Do A (reverse proxy through Zoraxy) for the web UI. It piggybacks on existing renewal. The mobile-app/API edge cases are usually fine if Zoraxy passes the WebSocket and preserves the Host header.

Mechanics: - Gateway on CT 109 uses DOCKER_HOST=tcp://<CT 104 socket-proxy>:2375 (the docker-socket-proxy already planned for CT 104) instead of the bind-mounted /var/run/docker.sock. socket-proxy ACL must allow containers, exec, images (read+write). - Migrate state files via volume tar: config.json, agents.json, prompts/, usage.db, gateway_tokens.json, nc_user_creds.json.

Investigated 2026-05-20:

The UDM Pro won't see \"nuc\" in its topology view because LLDP frames use the Nearest-Bridge multicast (01:80:c2:00:00:0e) which any 802.1D-compliant switch terminates by spec \u2014 and the D-Link DGS-1210-28P sits between the host and the UDM. LLDP-MED is not a fix for this; it's for endpoint (VoIP/MFP) discovery, not transparent LLDP forwarding.

Remediation paths in order of effort:

  1. Enable SNMP v2c/v3 on the DGS-1210 + add as a Generic SNMP device in UniFi \u2192 UDM sees the switch and can map port\u2194MAC. Most practical for this stack.
  2. Add snmpd to the host + generic SNMP device in UniFi \u2192 CPU/mem/iface stats from Proxmox visible in UniFi (not in topology, but in monitoring).
  3. UniFi-managed switch between host and UDM \u2014 clean answer; requires hardware.

D-Link DGS-1210 admin UI lives at http://192.168.1.10/. Verify the admin password is non-default \u2014 DGS-1210 ships with admin/blank or admin/admin on most firmware revisions.

Watch community.ui.com/RELEASES for a UniFi Drive release that adds: - NFSv4 export option (would enable idmap) - no_root_squash support (would enable server-side chown to specific uids) - Configurable anonuid/anongid (would let us match a real uid)

Any of these would let us simplify the CT 105 stack.

  1. Done 2026-05-20 \u2705:
  2. Memory / sizing: CT 101 160 \u2192 32 GiB; CT 102 512 MiB \u2192 1 GiB; HAOS balloon = 4 GiB
  3. Protection: CT 102 startup=1+protection; CT 108 startup=2+protection; CT 103/104/105/110/VM100 protection
  4. CT 110 (id) built at 192.168.1.5, Pocket-ID duplicated (online SQLite snapshot)
  5. ZFS: autotrim=on, atime=off rpool
  6. Backups: retention set on unas
  7. APT: duplicate sources removed; host unattended-upgrades deployed (Debian-only)
  8. Per-CT u-u: deployed to all 7 CTs with Debian-only allowlist
  9. Cron cleanup: removed weekly tteck-LXC-update curl-pipe-bash; removed daily broken apt-get upgrade -y; replaced /root/vm100.sh cron with vm100-watchdog.timer (1 min, lock-aware)
  10. Self-updaters: AdGuard (--update flag) Wed 03:30; Zoraxy (GitHub stable releases + rollback) Wed 03:40
  11. zpool upgrade rpool ran during the audit (enabled redaction_list_spill, raidz_expansion)
  12. Today with a maintenance window:
  13. Cut Zoraxy over to CT 110 for id.nuclide.systems (single upstream edit; rollback path = revert one line)
  14. apt full-upgrade (kernel 7.0.0-3 \u2192 7.0.2-5, pve-manager 9.1.11 \u2192 9.1.18) + reboot
  15. VM 100 disk options (cache=none, iothread=1) \u2014 \u00a74. Requires VM stop/start.
  16. Switch CT 105 from CIFS \u2192 NFS bind-mount (\u00a74). Test UID mapping.
  17. Drop the unas_smb storage once CT 105 is migrated.
  18. This week:
  19. Re-measure CT 104 peak RSS after fixing CT 101 \u2014 likely safe to drop to 48 GiB.
  20. Convert CT 105 to unprivileged (backup \u2192 restore as unprivileged).
  21. Raise ARC cap to 16 GiB.
  22. Probe NFSv4 against UNAS; switch if supported.
  23. Wire Postfix relayhost (Gmail/Postmark/your SMTP) so unattended-upgrades + zfs-zed + cron failures actually mail you.
  24. Rotate Backrest plan to back up real data (currently still pointed at /media/data-dir \u2014 a 50 KB test file from August 2025); see \u00a77.
  25. Medium term:
  26. Build CT 109 ops LXC (\u00a716) \u2014 Prometheus + Grafana + Arcane Manager + Dozzle + Homarr + Diun + Tinyauth
  27. Migrate Gotify from CT 104 to CT 109 (~30 min of env-var updates)
  28. Rotate exposed secrets that appeared in this transcript: Arcane OIDC_CLIENT_SECRET, ENCRYPTION_KEY, JWT_SECRET; Immich IMMICH_API_KEY
  29. Backrest: enable auth, redesign plans to cover all data tiers (\u00a77), front via Tinyauth for OIDC
  30. Next purchase window:
  31. Second NVMe \u2192 mirror rpool (\u00a76)
  32. proxmox-boot-tool init on the new disk
  33. 2.5 GbE NIC + matching switch port to UNAS for image-gen / backup speed
  34. UniFi-managed switch between host and UDM (or accept SNMP-only visibility from UniFi)

Note on Pocket-ID API keys: The key column in api_keys stores a SHA-256 hash of the real key (64-char hex). The plaintext key is only shown once at creation time in the UI. If lost, create a new one \u2014 there is no recovery path.

Login flow: In PVE web UI, select realm pocket-id at login. You will be redirected to https://id.nuclide.systems for authentication and returned to PVE. The email claim is used as the PVE username.

There is effectively no off-host backup of service data. The only configured Backrest plan covers /mnt/pve/unas/media/data-dir \u2192 jottacloud \u2014 i.e., Backrest backs up one specific UNAS path, not the services that write to UNAS.

Coverage:

This is a known gap. Plans: 1. Extend Backrest plans to snapshot tier-1 paths (Pocket-ID sqlite, Vaultwarden data, Gitea repos, Coder workspace homes) to jottacloud nightly. 2. Once the second NVMe lands (see infra/proxmox-state.md \u00a76), mirror rpool so a single disk death doesn't take everything.

The act of running this audit using Claude Code is itself a higher-bandwidth leak than the leak it audited. Hours of conversation about LUMEN-context data went to Anthropic; the original Lumen TR-004 cloud-sandbox breach was ~1,500 lines of Python.

This is a deliberate trade-off: - \u2705 Anthropic has stronger contractual guarantees than codesandbox.io (zero-data-retention API plans exist; Anthropic publishes a clear DPA). - \u2705 The operator chose Claude Code consciously, knowing all prompts are API-bound. - \u274c It is not free.

For LUMEN-specific deep analysis going forward, the hybrid path is the rational one: do schema/topology/code work in Claude Code (no Lumen payload needed); do data-touching analysis in a Coder workspace with the mcp-sandbox template + a local LLM. The S3 artifact hub (planned) enables both surfaces to share visualization output without ever exposing raw data.

  1. For any chat that will reference Lumen/Shepard data, switch to the air-gapped / local-LLM path. Don't mix.
  2. Strip secrets from chat replies aggressively. The Vaultwarden plaintext secret didn't need to be displayed; the agent could have written it to a tmpfs file and pointed the operator at it.
  3. Tag this and future audit transcripts in /docs/security/transcripts/ with a \"contains DLR-context data\" header so the policy is visible to anyone reviewing them.

Verdict: SENSITIVE DATA LEFT THE HOMELAB to an unapproved third party. The breach channel was lobe-cloud-sandbox, not the LLM inference.

Two off-host data flows, with very different trust profiles:

  1. LLM inference via SAIA / GWDG \u2014 21 assistant turns sent the full conversation context (incl. Shepard search results) to SAIA via LiteLLM. NOT a leak in this context \u2014 SAIA is operated by GWDG (German academic computing center, G\u00f6ttingen), vetted by DLR and integrated with the DLR IdP federation. For LUMEN (DLR engine programme) test data, SAIA is an approved partner.
  2. lobe-cloud-sandbox code execution \u2014 THE BREACH. 9 calls sent Python source code (with explicit LUMEN, P3-Lampoldshausen, LOX/LCH4 references, anomaly timings, and synthetic-but-derived-from-real timeseries) to api.lobehub.com + codesandbox.io \u2014 commercial third parties, not approved for DLR data. 4 exportFile calls pulled generated images back. Criticality: HIGH \u2014 proprietary aerospace IP in plaintext executable code, sent to commercial cloud.

Shepard data fetches themselves stayed on LAN (shepard-api.nuclide.systems), but the results were re-emitted to SAIA (approved) AND to the cloud sandbox (NOT approved).

  1. Artifacts tool returns empty. Every generateSVG / generateInteractiveHTML result had content length 0. The plugin is supposed to register the SVG/HTML as a side-panel \"artifact\" that the UI surfaces inline, but it returns nothing useful to the model \u2014 so the model has no handle/URL to reference.
  2. Model invents relative paths. Without a real URL, the model writes markdown like ![Timeline](timeline_view.svg) \u2014 relative paths against the SPA route, which returns index.html for any unknown path. That's why every \"link takes you to chat.nuclide.systems/\".
  3. No content store on the homelab. Even if the model asked \"save this SVG to a URL\", there's no integrated artifact storage today.

LobeHub's Artifacts works in Anthropic's hosted claude.ai because of client-side inline rendering. The self-hosted version's behavior here is broken / incomplete \u2014 either a config gap or the build is newer than the artifact-render code.

Two LobeHub conversations on the same task (LUMEN TR-004 failure analysis), 24 hours apart, with different models \u2014 compared for what leaked, where, and why.

Headline verdict. Session B (2026-05-21) was clean \u2014 all data stayed within the homelab + approved-partner perimeter (SAIA / GWDG, DLR-vetted, IdP-federated). Session A (2026-05-20) was a breach: 9 lobe-cloud-sandbox calls sent proprietary aerospace code+identifiers to commercial third parties (api.lobehub.com + codesandbox.io).

Same user prompt template both days. The model choice changed the tool selection: - qwen3.5-397b-a17b \u2192 reached for lobe-cloud-sandbox (full Python interpreter) \u2014 because it can generate complex matplotlib pipelines and execute them. - qwen3-coder-30b-a3b-instruct \u2192 reached for Artifacts (SVG + HTML generators) \u2014 code-focused model, prefers structured output over runtime execution.

Operational takeaway: model selection is a privacy control. A LobeHub policy that defaults sensitive chats to qwen3-coder-30b (or any model that doesn't reach for cloud sandbox) materially reduces the worst-case leak \u2014 even before you disable the sandbox plugin entirely.

The conversation triggered two distinct off-host data flows, both unavoidable in the current LobeHub configuration:

  1. LLM inference via Cerebras Cloud \u2014 every assistant turn (21 of them) sent the full conversation context (incl. Shepard search results) to api.cerebras.ai for inference on qwen3.5-397b-a17b. Criticality: HIGH \u2014 your prompts + retrieved Shepard data left the homelab.
  2. lobe-cloud-sandbox code execution \u2014 9 calls sent Python source code (with explicit LUMEN/P3-Lampoldshausen/LOX-LCH4 references and anomaly metadata) to LobeHub's hosted code interpreter (api.lobehub.com / codesandbox.io backend). 4 exportFile calls pulled generated images back.

The HTML wasn't actually executed (the artifact never rendered, see below), but if it had, the user's browser would fetch the library from a public CDN. Low risk; informational.

The Shepard MCP fetches and the Artifacts tool stayed on-LAN. No code interpreter / sandbox calls leaked code this time.

Three layered failures.

Root causes:

  1. Artifacts tool returns empty. Every generateSVG / generateInteractiveHTML result had content length 0. The plugin is supposed to register the SVG/HTML as a side-panel \"artifact\" that the UI surfaces inline, but it returns nothing useful to the model \u2014 so the model has no handle/URL to reference.
  2. Model invents relative paths. Without a real URL, the model wrote markdown like ![Timeline](timeline_view.svg) \u2014 these are paths relative to the page, which is the LobeHub SPA, which serves index.html for any unknown route. That's why every \"link takes you to chat.nuclide.systems/\" \u2014 the SPA's catch-all 200.
  3. No content store. Even if the model had asked \"save this SVG to a URL I can reference\", there's no integrated artifact storage on the homelab today.

LobeHub's Artifacts plugin works correctly in Anthropic's hosted Claude.ai because it has client-side rendering of artifact content inline. The self-hosted version's behavior is broken / incomplete in this build \u2014 known issue per [LobeChat issue #5xxx pattern]. Either it's a config gap or the build is newer than the artifact-render code.

  1. Provision Garage bucket chat-artifacts with two prefixes:
  2. pub/* \u2192 public-read (artifacts users paste into chats; lifetime e.g. 30 days)
  3. priv/<user-sub>/* \u2192 ACL-restricted to that user
  4. Fix the existing s3.nuclide.systems Zoraxy route (per PORTMAP.md \"Known Issues\" it's currently non-responsive \u2014 needs Garage external endpoint configured + the WebSocket-style header rules we applied today). Test with curl -I https://s3.nuclide.systems/chat-artifacts/health.
  5. Wire LobeHub artifacts \u2192 S3. Two paths:
  6. Fork / patch LobeHub Artifacts plugin to PUT generated SVG/HTML to S3 + emit absolute URL into the tool result. ~half-day of TypeScript.
  7. Sidecar interceptor that watches Lobe's artifact events (Postgres chat_messages writes? Or a custom MCP that supersedes Artifacts) and uploads. ~few hours.
  8. Add a generic upload_artifact MCP server to the gateway. Any agent (Claude Code in workspace, LobeChat, n8n) can upload(content, filename, mime) \u2192 returns URL. Single-store, multi-consumer. Recommended.
  9. Coder workspace integration: drop matplotlib's savefig \u2192 S3 path helper in the python-uv template's startup, so plt.savefig(\"s3://chat-artifacts/pub/<id>.png\") works. Then plots from workspaces, agents, and LobeHub all flow through the same URL space.
  10. Lifecycle policy on pub/* \u2014 delete objects after 30 days (Garage supports this via lifecycle config).

This solves more than just LobeHub picture rendering \u2014 it gives you a uniform \"show me a thing in a browser\" channel for every AI surface on the homelab.

SAIA: High sensitivity (proprietary test data), guaranteed reach (every turn). Mitigation = local LLM fallback for sensitive prompts. Check your GWDG data-sharing terms \u2014 academic providers often have softer privacy guarantees than commercial.

With the admin CLI API key (stored in Arcane DB, regenerate if needed): 

# Get or create an admin API key \u2014 see \"Admin API key\" section below\nAPI_KEY=\"arc_...\"\ncurl -s -X POST -H \"X-API-Key: $API_KEY\" -H \"Content-Type: application/json\" \\\n  \"http://192.168.1.40:10002/api/environments\" \\\n  -d '{\"name\":\"<ctname>\",\"apiUrl\":\"edge://<ctname>\",\"isEdge\":true}'\n# Note the environment id from the response\n

Step 2 \u2014 Generate and wire the AGENT_TOKEN

Arcane stores the raw AGENT_TOKEN in environments.access_token. Insert it via: 

# On PVE host, run: python3 /tmp/arcane-bootstrap.py\nimport argon2, secrets, sqlite3, uuid\nfrom datetime import datetime, timezone\n\ndb_path = \"/rpool/data/subvol-109-disk-0/opt/stacks/arcane/data/arcane.db\"\nenv_id  = \"<id from step 1>\"          # paste the environment UUID here\n\nconn = sqlite3.connect(db_path)\nraw_token = \"arc_\" + secrets.token_hex(32)\nkey_prefix = \"arc_\" + raw_token[4:12]\nph = argon2.PasswordHasher(memory_cost=65536, time_cost=3, parallelism=2)\nkey_hash = ph.hash(raw_token)\nkey_id = str(uuid.uuid4())\nnow = datetime.now(timezone.utc).isoformat()\n\nconn.execute(\n    \"INSERT INTO api_keys (id, name, description, key_hash, key_prefix, environment_id, managed_by, created_at, updated_at)\"\n    \" VALUES (?,?,?,?,?,?,?,?,?)\",\n    (key_id, f\"Environment Bootstrap Key - {env_id[:8]}\",\n     \"Auto-generated key for environment pairing\",\n     key_hash, key_prefix, env_id, \"system\", now, now))\nconn.execute(\"UPDATE environments SET access_token=? WHERE id=?\", (raw_token, env_id))\nconn.commit()\nconn.close()\nprint(\"AGENT_TOKEN:\", raw_token)\n

Step 3 \u2014 Add the agent to the CT's compose

  arcane-agent:\n    image: ghcr.io/getarcaneapp/arcane-headless:latest\n    container_name: arcane-agent\n    restart: unless-stopped\n    volumes:\n      - /var/run/docker.sock:/var/run/docker.sock\n      - ./arcane-agent:/app/data\n    environment:\n      EDGE_AGENT: \"true\"\n      EDGE_TRANSPORT: poll\n      AGENT_TOKEN: ${ARCANE_AGENT_TOKEN}\n      MANAGER_API_URL: http://192.168.1.8:10002\n    deploy:\n      resources:\n        limits:\n          cpus: \"0.5\"\n          memory: 256M\n

Add ARCANE_AGENT_TOKEN=<raw_token> to the CT's .env.

Step 4 \u2014 Start and verify

docker compose up -d arcane-agent\ndocker logs arcane-agent 2>&1 | grep \"Edge gRPC tunnel\"\n# Expected: Edge gRPC tunnel connected to manager  environment_id=<uuid>\n

The environment should flip to online in environments.status within ~5 seconds.

Pocket-ID 2.7.0 verifies client secrets with bcrypt (bcrypt.CompareHashAndPassword). The stored oidc_clients.secret column must be a 60-char bcrypt hash like $2a$10$... or $2b$10$....

A raw 64-char hex SHA-256 in that column silently fails every token exchange with invalid client secret. The Gitea and Coder clients on this host were initially provisioned that way and had to be regenerated.

To programmatically add or rotate an OIDC client secret in Pocket-ID:

# On Proxmox host (has python3-bcrypt installed)\npython3 <<'EOF'\nimport bcrypt, secrets, string\nalphabet = string.ascii_letters + string.digits\nplain = \"\".join(secrets.choice(alphabet) for _ in range(40))\nhashed = bcrypt.hashpw(plain.encode(), bcrypt.gensalt(rounds=10)).decode()\nprint(\"PLAINTEXT (give to client app):\", plain)\nprint(\"HASH (store in oidc_clients.secret):\", hashed)\nEOF\n

Always push the hash to Pocket-ID via a tmp file (pct push 110 ...) \u2014 never inline the bcrypt hash in a shell command, the $ chars get expanded.

To verify a client's secret is the right format: 

pct exec 110 -- sqlite3 /opt/stacks/pocketid/data/pocket-id.db \\\n  \"SELECT name, length(secret), substr(secret,1,7) FROM oidc_clients;\"\n# Working clients: length=60, prefix \"$2a$10$\" or \"$2b$10$\"\n# Broken clients : length=64, prefix is hex (e.g. \"1180664\")\n

Management-plane TLS (planned): issue/trust proper certs for admin-UI auth on the Proxmox host and the D-Link DGS-1210 (currently HTTP-only on the D-Link \u2192 admin creds in clear on the flat LAN; Proxmox self-signed). Brings switch/hypervisor mgmt onto the *.nuclide.systems PKI like the rest.

Network segmentation (planned): the LAN is flat \u2014 servers, IoT (Siemens oven, Dyson, Tapo cam, AWTRIX), consoles and phones all on one L2 (192.168.1.0/24, no VLAN, no L2 isolation). Plan an IoT VLAN (+ matching firewall zone) so untrusted appliances can't reach the server/Proxmox subnet. Complications to design around: the non-UniFi D-Link DGS-1210-28P switch (.10) and TP-Link RE700X extender (.187, NATs the Klipper printer .189) won't honour UniFi VLAN tags natively \u2014 segmentation needs a plan for the wired trunk through the D-Link and the repeater's bridge mode.

Why it's now a priority: the WAL-G archiver was hung silently for ~13 h (failed_count=0, zero base backups) and would never have been noticed; NFS stalls and SQLite-on-NFS damage are likewise silent. Monitoring must target exactly these silent-failure classes. - Placement: its own LXC on node nuc, NOT inside LXC 104 \u2014 104 hosts everything, so the monitor must survive/alert when 104 is down. - Stack: VictoriaMetrics (or Prometheus) + Grafana + Loki + Alertmanager \u2192 ntfy homelab-ai (already the alert channel). - Exporters/probes: node_exporter (per host + key LXCs), postgres_exporter \u00d73 (shared/lobe/immich), cAdvisor/docker, blackbox (HTTP + TLS-expiry for Zoraxy wildcard), pve-exporter (use the root@pam!mcp PVEAuditor token), and a custom WAL-G/archiver textfile collector: pg_stat_archiver (last_archived age, failed_count), .ready backlog, and wal-g backup-list newest-base age \u2014 per PG instance. - Alerts (priority order, derived from real incidents): 1. WAL archiver stalled (last_archived age > 15 m) or newest base backup > 26 h, any PG instance. 2. NFS mount on /mnt/pve/unas unresponsive / high op latency. 3. Config-drift guard: any *.db/*.sqlite* appears under /mnt/pve/unas (catches a regression of the tier-1 rule). 4. Container unhealthy/restart-looping > 5 m (the gluetun pattern). 5. local-zfs rpool or NFS pool > 85 %; 6. TLS cert < 14 d.

n8n is the right tool for event-driven pipelines (webhook on new file, Paperless webhook, Nextcloud activity, scheduled re-sync). For a bulk one-shot crawl, a Python script is better: - direct filesystem access with os.walk - proper progress bar and error recovery - batched Qdrant upserts (n8n does one HTTP call per node) - easy CLI: python3 ingest.py /mnt/pve/unas/Notizen

n8n handles the ongoing layer (see Ongoing ingestion).

OWUI's knowledge base already points at Qdrant (VECTOR_DB=qdrant). To surface documents from the documents collection in chat:

  1. Admin \u2192 Knowledge \u2192 Create Knowledge Base
  2. Name: \"Local Documents\"
  3. The collection is populated by ingest.py \u2014 OWUI will search it on #-prefixed RAG queries or when the knowledge base is enabled in a chat.

Note: OWUI creates its own internal collection names. To share the same documents collection between ingest.py and OWUI, use the OWUI API to create a knowledge base pointing to the pre-populated collection \u2014 or let OWUI manage its own collection and have ingest.py add documents via the OWUI knowledge API (POST /api/v1/knowledge/{id}/file/add). The OWUI API path is cleaner for OWUI search integration; the direct Qdrant path is better for external tools (n8n, MCP).

Note: Bifrost only supports one rate limit window per provider. The minute window is linked because it provides burst protection. The saia-hour / saia-day rows are in governance_rate_limits and can be linked by updating config_providers SET rate_limit_id='saia-hour' if needed.

Nexa is a personal AI middleware layer that sits between input sources and organisation tools. It is not a new app \u2014 it is a set of wired-together workflows running on top of services already deployed in nuclide.systems.

Mental model: - Memos = mouth and ear (voice interface, reply surface) - n8n = reflexes (workflow logic, classification, routing) - LiteLLM / SAIA = brain (language model gateway) - Qdrant = long-term memory (semantic recall) - Nextcloud = hands (tasks, calendar, files, mail)

The user types (or speaks) into Memos. A Memos webhook fires an n8n workflow. n8n classifies the input (Work vs. Personal, command vs. capture), calls LiteLLM for any reasoning, stores embeddings in Qdrant, and writes back a comment on the original memo. Side effects \u2014 task creation, calendar blocks, archive entries \u2014 go to Nextcloud.

"},{"location":"services/nexa/#embeddings-phase-31","title":"Embeddings (Phase 3.1)","text":"

The plan calls for TEI + bge-m3. Alternatives:

Option Pros Cons TEI + bge-m3 (plan) Lightest (~500 MB image, ~1.1 GB RAM), OpenAI-compatible, single model, no LLM runtime CPU-only (fine for the workload) Ollama (already on CT104?) Already deployed if running Heavier image, slower cold start, designed for chat not embedding throughput LiteLLM pass-through to Claude No new container 10 req/min rate limit \u2014 unusable for Qdrant ingest (2k Obsidian notes = 3 h) infinity (skip straight to Phase 3.2) Supports both text and visual models simultaneously Slightly more complex setup; Phase 3.2 is not urgent

Lean: deploy TEI now, swap to infinity when Phase 3.2 visual collection is needed.

Lean: use Exa MCP for Phase 2.4 (already available in the gateway), deploy SearXNG only if privacy or rate limits become a concern.

When CT 109 \"observe\" lands, /opt/stacks/ai/mcp-gateway/ moves to CT 109 (it's a control plane: OIDC, agent scheduling, token store, usage stats). The ~20 MCP child server containers in this CT (mcp-searxng, mcp-gotify, mcp-immich, mcp-fetch, mcp-time, comfyui-mcp, coder-mcp, kroki-mcp, etc.) stay here on CT 104.

The migrated gateway will reach this CT's docker daemon over the planned docker-socket-proxy (see /docs/proxmox-optimizations.md \u00a716). Until CT 109 exists, the gateway runs locally and uses the bind-mounted socket. Do not piecemeal-move the gateway; it's tied to the CT 109 build.

Standard pattern for docker volumes (verified via Karakeep, Q19): plain host bind-mount of /mnt/pve/unas/services/<svc>/<vol> from inside LXC 104. No driver_opts, no CIFS, no credentials in the compose. Karakeep, Immich and the rest do exactly this. Nexa follows suit. SMB-as-docker-volume is documented as an escape hatch only (docs/12 #27) for services that hit Nextcloud-style NFS issues \u2014 Nexa doesn't, so we don't use it.

Storage-layer snapshots are NOT configured on UNAS Pool 1 (\"Click to Setup\" in the UniFi Drive dashboard). All 2 TB of homelab data has no point-in-time protection at the storage layer \u2014 Backrest covers files, not \"the whole pool last Tuesday\". Highest-leverage fix in the homelab right now (docs/12 #38).

UNAS layout conventions (homelab-wide, all docker containers follow them): - services/<svc>/ is the general docker config store \u2014 every container in LXC 104 binds its persistent data here. Existing tenants observed: immich, karakeep, nextcloud, ntfy, paperless-ai, pocketid, shelfmark, stremio, traccar, vaultwarden, gluetun. Stale (retire, do not consume): services/siyuan/ (migrated to Obsidian), services/open-webui/ (unused \u2014 LobeHub is the active LLM UI), and services/dockge/ if it exists (retired in favor of Arcane). Nexa MUST follow the same pattern: services/nexa/{qdrant,tei-cache,graphdb,...}. Don't invent a parallel layout. - backup/<svc>/ \u2014 per-service backups (existing: home-assistant tars, immich pgdump, nextcloud borg). Nexa snapshots \u2192 backup/nexa/. - media/, code/, _sortMe/, dump/, test_perm \u2014 user data, not Nexa's concern. - Before deploying any Nexa container, READ AN EXISTING STACK in Arcane (e.g. karakeep or immich) to confirm the exact mount syntax in use \u2014 driver name, share path, credential injection pattern. Match it. The actual NFS export root is /var/nfs/shared/storage; the SMB share name is still TBD \u2014 see Q19 in docs/11.

Hard-blocklist for any Nexa indexer / agent (never read these paths or matching glob): - _sortMe/wallet/** \u2014 contains PGP keys + bitcoin wallet files. - Any path matching *.gpg, *.asc, *.key, *.pem, id_rsa*, *wallet*, *.kdbx, *credentials*, *secret*. - The Nextcloud appdata dir (services/nextcloud/appdata_*) \u2014 Nextcloud-internal, not user content. Intel iGPU passthrough is configured but currently broken \u2014 see docs/12 #26. - LXC 105 nextcloud \u2014 Nextcloud at nc.nuclide.systems. - LXC 106 octoprint \u2014 currently Exited; flagged in docs/11. - LXC 108 zoraxy \u2014 reverse proxy at 192.168.1.4:8000, TLS for *.nuclide.systems. - VM 100 haos \u2014 Home Assistant. - Already-running services on docker host (don't redeploy): - Memos :5230, n8n :5678, LiteLLM :4000 (UI LobeHub :3210), Qdrant (qdrant_scientific), ntfy :7998, Karakeep (legacy alias hoarder.nuclide.systems), Vaultwarden :11001, Pocket-ID :1411, Immich, Audiobookshelf, Paperless-ngx, Traccar, Prowlarr, plus MCP containers (crawl4ai-mcp, markitdown-mcp, papersearch-mcp). - Octoprint (LXC 106) is intentionally powered down most of the time. Phase-5 monitoring must skip names matching octoprint* rather than alert on its Exited state. - Obsidian vault lives inside Nextcloud at nc.nuclide.systems/Notizen/ (multi-device sync via Nextcloud client). Nexa accesses it via WebDAV \u2014 read-only, no filesystem mount.

Index target: Notizen/**/*.md. - Nextcloud Tasks lists & calendars (German names, may grow over time): - Pers\u00f6nlich \u2192 Personal context. - DLR \u2192 Work context (DLR is the user's employer). - Einkaufsliste \u2192 Shopping. - Wunschliste \u2192 Wishes. Lists are discovered by name at runtime (Qdrant _config namespace caches name \u2192 id). Never hardcode IDs. The discovery workflow runs daily and on cache-miss; new lists added in Nextcloud are honoured automatically next refresh. - Mail = Nextcloud Mail, single account fkrebs@nucli.de. No separate IMAP entry. The Waiting folder is a manual user signal \u2014 items there are skipped from digests. - Backup model is 3-2-1: UNAS native snapshots \u2192 s3.nuclide.systems (warm, on-site) \u2192 encrypted off-site cold tier (provider TBD, Jottacloud is the user's candidate \u2014 see Q20). Always restic/rclone-crypt before upload \u2014 third-party provider sees only ciphertext. Don't propose alternative backup paths without checking docs/12 #37 first. - Auth = Pocket-ID SSO is global at the Zoraxy layer. Don't add app-level basic-auth to Nexa surfaces; UIs inherit SSO. Machine-to-machine still uses API keys / app passwords. - Decided for Nexa (don't re-litigate without user input): - Vector store: reuse qdrant_scientific with collections suffixed by modality (nexa_knowledge_text, nexa_knowledge_visual). - Embeddings staged: Phase 3.1 TEI + BAAI/bge-m3 (text-only, 1024-dim). Phase 3.2 swap to infinity and add jinaai/jina-clip-v2 (768-dim, joint text+image space). All forward-compat fields (modality, media_uri, graph_iri, nexa:pendingVisualIndex) exist from 3.1 \u2014 adding the visual collection is additive. - Graph store: Ontotext GraphDB (SPARQL/RDF), Phase 3.4. RDF schema in docs/08 already includes nexa:modality / nexa:mediaUri / nexa:vectorCollection / nexa:pendingVisualIndex. - Chat model: SAIA via LiteLLM virtual key.

  1. Read docs/index.md first \u2014 it's the navigator.
  2. Open questions first. Before writing code or workflow JSON, scan docs/11-open-questions.md. If your task touches an unanswered Q, stop and ask rather than picking a default. Append new blockers to that doc as [ ] Q-NN.
  3. Optimization findings. When you spot infrastructure improvements, add them to docs/12-optimization-opportunities.md as a numbered bullet \u2014 don't just mention them in commit messages.
  4. Never inline secrets in workflow JSON or .env committed to git. Use n8n credentials, LiteLLM virtual keys, or (longer term) Vaultwarden.
  5. Keep deployment minimal. The default answer to \"do we need a new container?\" is no \u2014 the existing stack covers most needs.

nexa:vectorId + nexa:vectorCollection together are the bridge between graph and vector store. A SPARQL hit can trigger a vector lookup, and a Qdrant payload's graph_iri field walks back the other way.

nexa:modality, nexa:mediaUri and nexa:pendingVisualIndex exist from Phase 3.1 even though only the text path is wired up. Image attachments captured in 3.1 are recorded as nexa:Note with modality \"image\" and pendingVisualIndex true, then picked up by the Phase-3.2 backfill workflow \u2014 no data loss across phases.

Not every embedding deserves to live forever. Nexa indexes from several source types and each has its own expected lifetime.

#nexa:ask first searches existing memory. If the merged confidence is below a threshold (or the user adds --web to the command), Nexa runs a SearXNG query through redis-searxng, picks the top 3 results, fetches them through crawl4ai-mcp + markitdown-mcp, embeds the cleaned markdown, and answers from the augmented context.

Use HuggingFace text-embeddings-inference \u2014 single Rust binary, ~500 MB image, OpenAI-compatible API, loads exactly one model. Lighter than Ollama because there's no LLM runtime, no GGUF loader, no model registry.

The active docker manager on this LXC is Arcane (visible from Homepage as the running container manager \u2014 the LXC was originally provisioned with the Dockge helper-script template, but Dockge is now stale; see 12/#33).

mkdir -p /mnt/pve/unas/services/nexa/{tei-cache,qdrant,graphdb}\nmkdir -p /mnt/pve/unas/backup/nexa/snapshots/{qdrant,graphdb}\n

Memory budget: ~1.1 GB resident. First start downloads bge-m3 (~1 GB) into /mnt/pve/unas/services/nexa/tei-cache/; subsequent restarts are instant.

Secrets (SAIA_API_KEY, MEMOS_API_KEY, QDRANT_API_KEY, NC_APP_PASSWORD) go in the stack's .env next to the compose \u2014 same pattern Karakeep uses (env_file: .env). Arcane has an editor for it. Vaultwarden becomes the source-of-truth long-term (12/#11) but isn't required for the first cut.

Why bind-mount and not SMB? Earlier drafts of this doc proposed an SMB-via-docker-volume pattern because of the user's \"had it with Nextcloud\" experience. The Karakeep stack confirms the actual convention is the simpler one: host bind-mount of the LXC's existing /mnt/pve/unas NFS mount. The Nextcloud failure was Nextcloud-specific (its setup tooling chowns the data dir to www-data, which fails against root_squash exports) and doesn't apply to normal containers. SMB-as-docker-volume stays documented in 12/#27 only as an escape hatch if a future service hits Nextcloud-style issues \u2014 Nexa doesn't, so we don't use it.

Self-healing requirement (the user explicitly noted lists may change/grow): Nexa must not cache IDs forever. The #nexa:config workflow runs (a) on demand, (b) once daily as a scheduled refresh, and (c) automatically as a retry whenever a list/calendar lookup returns 404 or \"not found\". The runtime-config record in Qdrant's _config namespace stores {name \u2192 id, discovered_at} and gets invalidated on cache-miss. New lists added in Nextcloud surface in the next scheduled refresh and Nexa starts honouring #einkaufsliste / #dlr etc. without code changes.

Observations from the running infrastructure. Each item is independent \u2014 accept, defer, or reject.

"},{"location":"stacks/nexa/docs/12-optimization-opportunities/#for-nexa-directly","title":"For Nexa directly","text":"
  1. Reuse, don't redeploy. The earlier DEPLOYMENT.md would have spun a second Memos / n8n / Qdrant. The current homelab already runs all three. The new 09-deployment treats these as pre-existing \u2014 keeps the config minimal and avoids port collisions.
  2. Use LiteLLM virtual keys per logical caller. Today there's one SAIA key. Issuing one key per workflow (nexa-router, nexa-embed, nexa-digest) lets you set different per-key rate/cost limits and disable a single workflow without rotating everything.
  3. Use n8n's credential objects, never inline secrets. The current workflows under nexa-core/n8n-workflows/phase-1/*.json should be reviewed \u2014 if any header Authorization is hardcoded, replace with credential references before importing.
  4. Centralise system alerts on a single ntfy topic (nexa.system). Backrest, Proxmox notifications, n8n failure-webhook and the Octoprint Exited state all go to that topic; one Memos system memo aggregates them.
  5. Defer graph DB until Phase 3.4. Qdrant alone covers ~80% of the assistant's daily value. The graph DB is justified once you actually need dependency analysis or critical-path queries.
  6. Auto-export n8n workflows. nexa-core/scripts/backup_workflows.sh already exists. Schedule it inside the n8n container (cron) and let it git commit && git push \u2014 this is the cheapest disaster recovery.
"},{"location":"stacks/nexa/docs/12-optimization-opportunities/#for-the-wider-homelab-out-of-scope-but-worth-noting","title":"For the wider homelab (out of scope but worth noting)","text":"
  1. AI gateway naming. ai.nuclide.systems currently proxies LobeHub (a chat UI on :3210), while the LiteLLM API lives on :4000. For Nexa, point n8n directly at LiteLLM (http://192.168.1.40:4000 over the docker net \u2014 no public TLS hop needed) to save latency and isolate from UI restarts.
  2. MCP servers consolidation. Dozzle shows crawl4ai-mcp, markitdown-mcp, papersearch-mcp running individually. They're all MCP servers \u2014 Nexa Phase-3 could pull from these via LiteLLM's MCP support to enrich the embedding pipeline (e.g. fetch + markitdown a Karakeep link before embedding).
  3. Backup the n8n SQLite file \u2014 Backrest covers /home/node/.n8n if added; today the only \"backup\" is the workflow JSON which omits credentials and execution history.
  4. Pocket-ID SSO in front of n8n would let you remove n8n basic-auth and unify session management across the whole stack. One-time setup, large UX win.
  5. Vaultwarden as the secret store for Nexa secrets (SAIA_API_KEY, MEMOS_API_KEY, \u2026) \u2014 read at bootstrap via the Bitwarden CLI from inside the docker host. Removes the need for a .env on disk.
  6. AdGuard as DNS-based control plane. Since AdGuard is the resolver for the LAN, you can rewrite *.nuclide.systems to 192.168.1.4 (Zoraxy) internally and avoid a hairpin via the WAN \u2014 already the case if AdGuard rewrite rules are set, worth verifying.
  7. Disk usage on LXC 104 is 47.7 % (Proxmox). Monitor; n8n execution logs and Dozzle history are the usual culprits. Setting EXECUTIONS_DATA_PRUNE=true and EXECUTIONS_DATA_MAX_AGE=168 (7 days) on n8n keeps it bounded.

  8. Vector-store sprawl in the homelab \u2014 three competing indexes today. Nexa is about to be the fourth. Track for eventual consolidation:

    Long-term, Nexa is the natural single source of truth (it sees memos + mail + obsidian + RDF graph). Once its RAG is satisfying, retire the Obsidian-plugin indexes and consider letting Nexa read from Paperless-AI's ChromaDB rather than re-embed PDFs (one-line ChromaDB query, much cheaper than redoing OCR-to-vector). Track but don't act yet.

  9. Retire open-webui. Confirmed stale by the user \u2014 only LobeHub is in active use as the LiteLLM chat front-end (ai.nuclide.systems). Stop the container, tar services/open-webui/ into backup/open-webui/, then remove the stack. Frees ~500 MB RAM + a couple of GB of model cache.

  10. services/siyuan/workspace/ is dead data. SiYuan retired, content migrated to Obsidian (Nextcloud Notizen/). Keep a final tar in backup/siyuan/, then rm -rf services/siyuan/. Frees disk + removes a \"is this still authoritative?\" question for future agents (and for Nexa's classifier if it ever sees the path).

  11. Real-time Obsidian sync via notify_push. Phase 3.1 polls WebDAV every 15 min (Q4 resolution). Once that works, swap to Nextcloud's notify_push app for sub-second propagation. One-line workflow change in n8n.
  12. assets/ is 186 MB of binaries in the Obsidian vault \u2014 worth a glance to confirm it's mostly images (Phase-3.2 visual queue) rather than something that should live in Nextcloud Files proper.
  13. Paperless-AI as a Phase-2.x triage helper for _sortMe/Downloads/. UNAS shows ~230 PDFs/docs in _sortMe/Downloads/ plus another batch under _sortMe/Anne/. Paperless-AI (already running) can ingest, OCR, classify and route them; Nexa's role is to delegate \u2014 wire a workflow that posts a batch to Paperless-AI and reports the result back via Memos.
  14. media/Recipes/ has ~300 individually-named recipe folders. Once Phase-3.1 text indexing works, this becomes a high-quality test corpus for #nexa:ask (e.g. \"what was that gochujang noodle recipe with no anchovies?\"). Out-of-scope for the deployment plan, but a satisfying first user-facing win.

  2. Enable KSM (Kernel Same-page Merging). With ~40 docker containers + several LXCs, KSM typically frees 1\u20133 GiB by deduplicating identical memory pages. Currently KSM sharing: 0 B in the summary. PVE has ksmtuned available \u2014 systemctl enable --now ksmtuned.
  3. Suppress the pve-no-subscription repository warning \u2014 either accept it (it's a homelab) and apply the pve-no-subscription-warning polyfill, or move to the enterprise repo. Pure cosmetic, but the orange banner in the UI is noise.
  4. Swap is 31 GiB on a 62 GiB box with ZFS root \u2014 almost certainly oversized. Drop vm.swappiness to 10 (sysctl -w vm.swappiness=10 + persist) so swap is only used under genuine pressure, and consider shrinking the swap volume if disk-layout permits.
  5. Verify scheduled ZFS scrub is enabled. PVE ships zfs-scrub-monthly@.timer \u2014 systemctl list-timers | grep zfs to confirm. Cheap insurance on a 1.6 TiB pool.
  6. SMART monitoring on the NVMe. smartctl -a /dev/nvme0 should be regularly polled; PVE's notification target can ntfy on degradation. Combine with the existing nexa.system ntfy topic (optimization #4) so disk-health alerts land in the same Memos system feed as everything else.
  7. NTP source via AdGuard. AdGuard already resolves DNS for the LAN; pointing the host's systemd-timesyncd at pool.ntp.org resolved through AdGuard avoids any external dependency for time. One-line change in /etc/systemd/timesyncd.conf.
  8. fstrim.timer enabled for the SSD pool \u2014 verify with systemctl status fstrim.timer. Default-on in modern PVE, but quick to confirm.
  9. Watchdog config is irrelevant for a single-node setup (HA is the use case), so leave the default. Mentioned only so future agents don't add it speculatively.

Confirmed allocation: 16 CPU, 31.25 GiB RAM (7.86 GiB used / 25%), 8 GiB swap (idle), 200 GiB boot disk at 47.7% used \u2014 disk pressure outranks RAM pressure.

  1. Fix the Intel iGPU passthrough. The container's own notes flag the binding as \"likely failing\". Once /dev/dri/{card0,renderD128} is visible inside the LXC, both TEI and infinity can run embeddings on the Arc iGPU via OpenVINO / IPEX-LLM \u2014 typically 5\u201310\u00d7 faster than CPU. Equally, Immich's CLIP can be GPU-accelerated. The required config in /etc/pve/lxc/104.conf: 
    lxc.cgroup2.devices.allow: c 226:0 rwm\nlxc.cgroup2.devices.allow: c 226:128 rwm\nlxc.cgroup2.devices.allow: c 29:0 rwm\nlxc.mount.entry: /dev/dri/card0       dev/dri/card0       none bind,optional,create=file\nlxc.mount.entry: /dev/dri/renderD128  dev/dri/renderD128  none bind,optional,create=file\nlxc.idmap: u 0 100000 65536\nlxc.idmap: g 0 100000 65536\nlxc.idmap: g 44 44 1            # video group on host\nlxc.idmap: g 104 104 1          # render group on host\n
    Then inside the container: usermod -aG video,render <docker-user> and run TEI with --device cuda replaced by the OpenVINO build (text-embeddings-inference:cpu-1.5-openvino). Not needed for Phase-3.1's volume but a clean upgrade path.

  2. Match the homelab-wide UNAS storage convention \u2014 host bind-mount of /mnt/pve/unas/services/<svc>/<vol>. Verified via the running Karakeep stack (Q19): every container in LXC 104 binds its persistent data into /mnt/pve/unas/services/<svc>/... directly, no driver_opts, no CIFS, no credentials in compose. Nexa follows the same pattern. Targets:

    Pre-deploy step: mkdir -p /mnt/pve/unas/services/nexa/{qdrant,tei-cache,graphdb} and mkdir -p /mnt/pve/unas/backup/nexa/snapshots/{qdrant,graphdb} on the docker LXC. Then the compose volumes block is just - /mnt/pve/unas/services/nexa/<vol>:/<container-path>. Concrete example in 09-deployment \u00a7Step 3.

    Secrets go in the stack's .env next to the compose (Karakeep convention: env_file: .env). Vaultwarden is the long-term source-of-truth for those secrets (12/#11) but isn't required day-one. The earlier proposal of mounting SMB as a docker volume is withdrawn (12/#27) \u2014 it was an over-fitting to the Nextcloud-specific NFS issue. 32. The LXC has its own 8 GiB swap. Combined with the host's 31 GiB, that's a lot of swap for guests that should never page. Drop the LXC swap allocation to 1\u20132 GiB (pct set 104 -swap 2048) \u2014 frees disk on the LVM-thin pool and forces issues to surface earlier rather than silently swap. 33. Stacks are managed in Arcane; Dockge is stale. The LXC was originally provisioned with the Dockge helper-script template, but the user moved on to Arcane as the day-to-day docker manager. Deployment of the Nexa stack therefore goes through Arcane, not Dockge. Cleanup task: tar services/dockge/ (if it exists) into backup/dockge/, retire the Dockge container, drop the stale data dir. Dozzle stays \u2014 it's the log viewer, not a manager, so it isn't redundant with Arcane. 34. Untriaged local mail on the LXC. Console shows You have new mail. at login \u2014 the system mail spool on /var/mail/root has unread messages, almost always cron job failures. mailx or mutt to inspect, then either fix the failing job or send the spool to nexa.system ntfy via a tiny aliases entry (root: |/usr/local/bin/spool-to-ntfy.sh).

These three are inter-related \u2014 picking them up as one campaign is cheaper than chasing each individually, because the audit step is the same. They also map cleanly onto Phase 6 (Nexa as homelab steward): once Nexa can poll Arcane, diff against the documented state and emit actionable findings, items #35\u201337 become semi-automatic \u2014 Nexa proposes the migrations rather than us hunting them down.

  1. Consolidate Postgres instances. Today there are at least four independent Postgres containers running \u2014 visible from Arcane: immich_postgres, lobe-postgres, litellm_db, paperless-ngx-db-1 (Karakeep uses Meilisearch + maybe SQLite, separate). Each idles around 100\u2013300 MB RAM and has its own backup story. Two paths:

    Pre-step: list every running container with docker ps --format '{{.Names}}\\t{{.Image}}' | grep -i 'postgres\\|mariadb\\|mysql' to inventory exactly what's running.

  2. UNAS-integration audit. /mnt/pve/unas/services/<svc>/ is the homelab convention (host bind-mount, no driver opts \u2014 see #31). Not every container follows it yet. Walk every Arcane stack and check the volumes: block: any - /var/lib/docker/... or anonymous-volume entry is non-compliant. Suspected non-compliant (need verification):

    Output: a one-page table service | persistent? | currently bound to | should be bound to. Then migrate the non-compliant ones one-by-one (stop \u2192 rsync data to services/<svc>/ on UNAS \u2192 re-create stack with the new bind \u2192 verify \u2192 keep the old volume for 7 days as a rollback). Lock the convention for any new stack going forward.

  3. 3-2-1 backup tiering: warm on-site (S3) + cold off-site. s3.nuclide.systems is already up but it's on-site \u2014 same building, same power, same (in-)susceptibility to fire / theft / ransomware. By itself it's a warm tier, not a disaster-recovery copy. The full design is two tiers:

    Warm tier \u2014 s3.nuclide.systems (already exists, just needs a bucket): - Restic / borg repos for backup/home-assistant/, backup/immich/, backup/nextcloud/, future backup/nexa/. Backrest already orchestrates Borg \u2014 just add the S3 destination. - Qdrant + GraphDB snapshots flow UNAS \u2192 S3 daily. - Resolves Q12 once the bucket name + access key are set.

    Cold tier \u2014 off-site provider (decision pending \u2014 see Q20): - Jottacloud \"Unlimited\" (~\u20ac9.50/mo, EU/Norway, soft-cap ~5 TB) \u2014 user's stated candidate. Best price/value at current 2 TB; reach soft cap in ~10 years. Use rclone jottacloud: or native jotta-cli. - Hetzner Storage Box BX21 (\u20ac13/mo, 5 TB EU/DE) \u2014 predictable quota, native Borg/Restic/SFTP. Cheapest predictable EU alternative. - Backblaze B2 (~$12/mo for 2 TB, S3-compatible, US) \u2014 cheapest with the widest tooling support; egress is paid (~$10/TB) which only bites during full restores. - rsync.net (~$30/mo) \u2014 ZFS send/recv natively; overkill unless you want pool replication. - Storj DCS ($4/TB/mo, decentralized, S3-compatible) \u2014 newer ecosystem.

    Always encrypt before upload regardless of provider \u2014 restic or rclone crypt over the chosen remote. The provider sees only ciphertext blobs. Key material lives in Vaultwarden + a printed-paper offline copy.

    Tiering & cadence: 

    [Source]   UNAS RAID-6 + native snapshots (#38)\n             \u2502 daily restic/borg\n             \u25bc\n[Warm]     s3.nuclide.systems (on-site, fast restore)\n             \u2502 weekly rclone copy + crypt\n             \u25bc\n[Cold]     Off-site (Jottacloud / B2 / Hetzner)  \u2190 satisfies the \"1\" in 3-2-1\n

    What goes off-site (priority order): 1. Immich photo originals \u2014 irreplaceable. 2. media/documents/, _sortMe/Downloads/, Nextcloud user data \u2014 irreplaceable. 3. Memos DB, n8n workflows, Nexa Qdrant + GraphDB snapshots \u2014 replicable from sources but expensive to redo. 4. Vaultwarden DB \u2014 cryptographically sensitive but small; explicitly include.

    What does not need off-site: movies, music, audiobooks, ROMs, derived caches (Immich thumbnails, encoded-video). Those re-download or regenerate.

    Pre-deploy step: choose one provider, create a test bucket/folder, dry-run a restic init + restic backup of backup/nexa/ first as a smoke test before pointing the heavyweight repos at it.

  4. Configure UNAS Pool snapshots. The UniFi Drive dashboard shows the storage-pool snapshot schedule as \"Click to Setup\" \u2014 i.e. not configured. RAID 6 protects against drive failure, not against an rm -rf from a misbehaving container or a Nextcloud user mass-delete. Cheap fix: set a daily snapshot with 7-day retention + a weekly with 4-week retention on Pool 1. Native to UniFi Drive, no agent needed. Highest-leverage data-protection change in the homelab right now \u2014 costs nothing, recovers everything.

  5. Use UNAS native snapshots for fast Nexa rollback once #38 is set. Nexa workflows that mutate large state (re-embedding the whole vault, graph rebuild, list-config rewrite) can pre-snapshot \u2192 operate \u2192 verify \u2192 release against the same UniFi Drive snapshots. Cheaper and faster than restoring from S3.
