- /docs/ now contains 12 numbered guides + index.md (navigator).
- Old duplicates removed: nexa-core/doc/, DEPLOYMENT.md, PLAN.md,
config/{classification_logic,workflows_spec}.md.
- 09-deployment.md targets the running infra (LXC 104 docker host,
Zoraxy at 192.168.1.4, existing Memos/n8n/LiteLLM/Nextcloud/Qdrant)
rather than spinning a parallel stack; minimal-config approach.
- 11-open-questions.md tracks user-info-required blockers.
- 12-optimization-opportunities.md captures homelab tweaks.
- CLAUDE.md added so future agent runs know repo conventions and infra.

## Components
|
|
|
|
| Component | Role | Where it runs (today) |
|
|
|-----------|------|-----------------------|
|
|
| **Memos** | Interface, voice input, webhook source | docker host LXC 104 → `memos.nuclide.systems` |
|
|
| **n8n** | Workflow / logic engine | docker host LXC 104 → `n8n.nuclide.systems` |
|
|
| **SAIA / LiteLLM** | Model gateway, embeddings, classification | docker host LXC 104 → `ai.nuclide.systems` (LiteLLM internal :4000) |
|
|
| **Qdrant** | Vector memory (semantic recall) | docker host LXC 104 (existing `qdrant_scientific` may be reused — see [11](./11-open-questions.md)) |
|
|
| **Graph DB** | Structural memory (deferred) | not yet deployed |
|
|
| **Nextcloud** | Tasks, calendar, mail, files | dedicated LXC 105 → `nc.nuclide.systems` |
|
|
| **ntfy** | Push channel for system alerts | docker host → `ntfy.nuclide.systems` |
|
|
| **Backrest** | Backup orchestration | LXC 103 |
|
|
| **Zoraxy** | Reverse proxy + TLS | LXC 108 (`192.168.1.4:8000`) |
|
|
| **AdGuard DNS** | Internal name resolution | LXC 102 |
|
|
| **Home Assistant** | Voice + house automation | VM 100 (HAOS) |
|
|
|
|
## Two-pillar memory
|
|
|
|
- **Qdrant** answers *"what is similar / relevant?"* (cosine search over embeddings).
|
|
- **Graph DB** answers *"who, what depends on what, how is it structured?"* (Cypher / SPARQL).
|
|
|
|
Both pillars are queried in parallel for `#nexa:ask` and merged before SAIA generates the final answer. See [08 — GraphRAG architecture](./08-graphrag-architecture.md).
|
|
|
|
## Dual-context routing
|
|
|
|
Every input is classified `work` or `personal` before any side effect (task creation, calendar write). See [04 — Integration matrix](./04-integration-matrix.md) and [06 — Classification logic](./06-classification-logic.md).
