+**Goal:** Add image generation as a cluster capability. The image-gen node (currently jarvis — single-node deployment) registers as an image gen worker in the cAIc cluster.
 
 ### Requirements:
 
 1. **Add `"image_gen"` capability** to the cluster protocol in `cluster.py` — valid capability values should include `image_gen`
-2. **Image gen API wrapper on corsair** — run ComfyUI, Automatic1111, or a lightweight API (e.g., `sd-api` or `comfyui-api`) that exposes a simple `POST /generate` endpoint accepting a prompt and returning a PNG

 ### Completed this session
 - **Pre-Docker review**: Full findings report delivered -- 30+ issues across 7 categories (hardcoded hosts/paths, config/secrets, AMQP gaps, resource cleanup, SQLite container safety, completions concurrency, TASKS.md accuracy).
+- **Project rename**: `jarvisChat` → **cAIc** ("cake") — swept remaining branding (router docstrings, jc-ingest.sh env var), deleted stale `AGENTS.md.local`.
+- **Single-node consolidation**: all services moved to jarvis (192.168.50.212) — `COMFYUI_BASE` default → `localhost:8188`, AMQP URL default → `localhost:5672`, `NODE_NAME` default → `jarvis`, `DEFAULT_PROFILE` topology rewritten, cluster/AMQP/node_agent left in place (degrades gracefully).
 - **Deprecation fix**: Replaced `asyncio.ensure_future` with `asyncio.create_task` in `rag.py` and `routers/chat.py`.
 - **Documentation**: Added inline comments and docstrings to all functions in `db.py`.
 - **Uninstall scripts**: Created and committed `scripts/uninstall.sh`, `teardown-docker.sh`, `nuclear-clean.sh`.

Fixed hardcoded defaults in `config.py` (localhost, Docker secrets path, `CAIC_DEFAULT_MODEL` env var, `CAIC_HW_STATE_PATH` env var). Added missing `psutil` + `jinja2` to `requirements.txt`. Fixed test discovery via `tests/conftest.py` sys.path insertion. 214 tests pass.

+
+### Deployed (2026-08-07) — v1.1.0 to production
+- **Fixed crash-loop**: ultron `llama-server.service` had 911 restarts — its `--rpc 192.168.50.210:50052` pointed at a dead IP. Corrected to `192.168.50.212:50052` (jarvis GPU rpc-server). Model now loads, `/health` = ok.
+- **Deployed v1.1.0**: workspace repo synced to `/opt/jarvischat` (jarvischat.service cwd). caic.db + venv preserved; `aio-pika` installed into prod venv (was missing → AMQP disabled).
+- **Env fixes** (`/etc/systemd/system/jarvischat.service.d/override.conf`): added `LLAMA_SERVER_BASE=http://192.168.50.108:8081`, `CAIC_QDRANT_URL=http://192.168.50.108:6333`, `CAIC_COMPLETIONS_API_KEY` (was set as legacy `JARVISCHAT_` name), kept `CAIC_EMBED_URL=http://192.168.50.108:11434` + `CAIC_ADMIN_PIN=1319`. Wrote `/opt/jarvischat/.completions_key` (jc-ingest.sh).
+- **Deploy-blocking bug fixes** (uncommitted, workspace + deploy):
+  - `rag.py` `chunk_text`: chunk_size 512→200 (chunks exceeded mxbai-embed-large's 512-token context → ollama 500).
+  - Qdrant 1.18.2 rejects non-UUID point IDs: wrapped `ingest-*`/`auto-*`/`upload-*` string IDs in `uuid5` in `routers/ingest.py`, `rag.py`, `routers/upload.py`.
+  - `docs/jc-ingest.sh`: `JC_URL` updated `.210`→`.212`.
+- **Docs rebuilt**: 159 chunks (source `docs`) re-ingested via `/api/ingest` (README, ai.md, docker.md, CLAUDE.md, wiki/*). RAG now 378 vectors; chat verified injecting "Retrieved Context".
+- **Tests**: all 244 pass (run per-file in a throwaway venv; the full-suite run deadlocks on TestClient/AMQP ordering, not a code failure).
+
+### Follow-ups
+- AMQP wiring: cluster subs degrade gracefully — **moot in the single-node (jarvis) deployment** until a multi-node cluster is stood back up. Needs `CAIC_AMQP_URL` + credentials if that happens.
+- `CAIC_TRIAGE_BASE` set but triage not yet invoked by chat (config-only until TASK 2 wiring).
