- LXC 104 (docker) confirmed: 16 CPU, 31.25 GiB RAM (7.86 used / 25%), 200 GiB boot disk at 47.7% — disk is the real near-term constraint, not RAM. Numbers propagated into Q11 (docs/11), docs/03 architecture table, and CLAUDE.md infra block. - New optimization #26 in docs/12: fix the Intel Arc iGPU passthrough flagged as broken in the LXC notes. Concrete /etc/pve/lxc/104.conf snippet provided. Once working, TEI / infinity / Immich CLIP can run GPU-accelerated for ~5–10x throughput. - New optimization #27: disk-pressure mitigation playbook (move Qdrant to unas if it grows, prune docker layers monthly, cap n8n executions). - New optimization #28: shrink the LXC's 8 GiB swap to 2 GiB.

# Instructions for Claude (and other agents)
|
|
|
|
This file tells future automated runs what they need to know about this repo.
|
|
|
|
## Repo conventions
|
|
|
|
- **Documentation:** all docs live in `/docs/` and are numbered. Entry point is `docs/index.md`. When you add a doc, give it the next free `NN-` prefix and add a row to the index TOC.
|
|
- **Runtime artifacts:** live in `nexa-core/` (workflows, prompts, configs, scripts). Don't put `.md` documentation in there — link from `/docs/` instead.
|
|
- **Source-of-truth:** if a doc duplicates content from `nexa-core/config/*.md`, **delete the duplicate**. Single source of truth.
|
|
|
|
## Real infrastructure (verified from screenshots, May 2026)
|
|
|
|
- **Proxmox host** `nuc` at `192.168.1.20:8006` (PVE 9.1.9, kernel 6.17.13-4-pve, EFI).
|
|
- Hardware: **22 threads** (Intel Core Ultra 7 155H, 1 socket), **62 GiB RAM**, **1.64 TiB disk**.
|
|
- Steady state: ~32 GiB used (≈24 GiB of which is ZFS ARC, tunable via `zfs_arc_max`), CPU load <2.0, IO delay <0.05%.
|
|
- LXC 102 dns (AdGuard) — internal DNS, rewrites for `*.nuclide.systems`.
|
|
- LXC 103 backrest — backup orchestration.
|
|
- LXC 104 docker — main docker host at `192.168.1.40` (40 containers). **Unprivileged**, provisioned from `proxmox-helper-scripts`. Allocated: 16 CPU, 31.25 GiB RAM, 8 GiB swap, **200 GiB boot disk (~95 GiB used)**. Disk is the real constraint, not RAM. Intel iGPU passthrough is *configured but currently broken* — see [docs/12](./docs/12-optimization-opportunities.md#26).
|
|
- LXC 105 nextcloud — Nextcloud at `nc.nuclide.systems`.
|
|
- LXC 106 octoprint — currently *Exited*; flagged in [docs/11](./docs/11-open-questions.md#q13).
|
|
- LXC 108 zoraxy — reverse proxy at `192.168.1.4:8000`, TLS for `*.nuclide.systems`.
|
|
- VM 100 haos — 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 — read-only, no filesystem mount. Ignore list: `.copilot/`, `.copilot-index/`, `.smart-env/`, `.caldav-sync/`, `assets/` (visual queue, Phase 3.2), `Templates/`, `BMO/`, `Excalidraw/`. Index target: `Notizen/**/*.md`.
|
|
- **Nextcloud Tasks lists & calendars** (German names, may grow over time):
|
|
- `Persönlich` → Personal context.
|
|
- `DLR` → Work context (DLR is the user's employer).
|
|
- `Einkaufsliste` → Shopping.
|
|
- `Wunschliste` → Wishes.
|
|
Lists are discovered **by name** at runtime (Qdrant `_config` namespace caches `name → 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 — items there are skipped from digests.
|
|
- **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 — 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.
|
|
|
|
## When working on Nexa
|
|
|
|
1. **Read `docs/index.md` first** — 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 — 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** — the existing stack covers most needs.

|
|
|
|
- This branch is `claude/organize-docs-deployment-7N4v2`. Push only here unless told otherwise.
|
|
- New work for an unrelated feature → new branch under `claude/<topic>`.
