 ## Recent decisions
 
+- `[2026-06-15]` **arbo engine rebuilt v0.11.6 → v0.11.22 from main; catalog re-applied (v0.11.23) — curated `/workflows` footer live.** src/ schema changes (Model/Lora.summary, Workflow.blurb/keywords + the /workflows endpoint) need a MANUAL image rebuild (the webhook warns-only on `src/`/`Dockerfile`). Built from `/worktank/arbo/repo`, bumped `ARBO_IMAGE` in the host .env, recreated + verified healthy (auto-rollback armed, unneeded). comfy-dev's v0.11.20 catalog push had first crash-looped prod (old baked schema `extra=forbid` vs new git-mounted catalog fields → ValidationError); they reverted the catalog, so rebuild-from-main loaded clean, then they re-applied (v0.11.23). comfyui is a SEPARATE compose project — the rebuild didn't touch it.
+
+- `[2026-06-15]` **althing-core refreshed to v0.14.1 box-wide on nh3-dev** (forseti + heid both routed it; central-sequenced per DevOps-delegation since `uv tool install --force` swaps the shared binary all handles use). Fixes the monitor non-truncating-lock bug so `stop-monitor`/`--stop` reliably recovers orphans. The editable install (`uv tool install --force --editable .`) covers every nh3-dev handle; `--version` trued up 0.14.0→0.14.1; verified `--stop` works against a real orphan.

 - `[2026-06-15]` **ratatoskr Tier-3 affect live smoke GREEN** (consumer-confirmed). Brokered/minted consumer_id="ratatoskr" Heimdall HS256 key on personal Worldtree (the key IS BOTH the create-session Bearer AND ratatoskr's JWT verifier secret — plain utf-8 string, NOT base64/raw); injected ENV-ONLY to `~/.config/ratatoskr/provider.env` (mode 600) on nh3-dev; added `10.100.10.50:8390` to personal's `BIFROST_CLIENT_ALLOWED_HOSTS`; drove define→session (handshake 200)→turn→affect.emit (200, snapshot persisted). Worldtree signs Bifrost with the caller's raw Bearer verbatim. Drive commands + claims contract in althing thread `01KV4ZYSE3…`.
 
 - `[2026-06-15]` **Dense Qwen3-VL-32B-NVFP4 A/B'd as arbo's anatomy hero-judge vs the qwen3.6-35b-a3b MoE → dense LOST, pilot torn down, GPU 0 reclaimed.** Dense NVFP4 loads clean on vLLM where the MoE NVFP4 doesn't (no expert-scale keys); ~44 tok/s on Blackwell GPU 0; vision tower stays high-precision. But comfy-dev's ground-truth A/B: MoE wins (faster + dual-use as general LLM + slight fine-detail edge), and the subtle-proportion tier is below ALL VLs. **Don't re-propose a dense-VL judge swap.** (auto-memory `project-qwen3vl-dense-pilot`)

 ## Tried and abandoned
 
+- `[2026-06-15]` **A comfyui restart-loop with `exit 0` + `OOMKilled=false` is NOT OOM — suspect a native SEGFAULT.** `docker inspect` shows only the LAST exit code; a GPU OOM is a catchable `RuntimeError: CUDA out of memory`, NEVER `Fatal Python error: Segmentation fault`. Diagnostic: `RestartCount>0` = same container restarted in-place → the docker json-log ACCUMULATES across all cycles, so grep the full `docker logs` for the crash signature + the lines right before each restart banner. comfyui's was at VAE decode (sampling completes, then segfault loading `AutoencodingEngine`) — gen-triggered but native, not VRAM. Suspects logged: torch/cu130 mismatch, an injected `aimdo` cuda-funchooks lib, the VAE.
+
+- `[2026-06-15]` **NEVER blanket-kill `althing-light-monitor` by PID** — they're per-handle and MANY agents run their own on the shared nh3-dev box (heid / ratatoskr-dev / worldtree-dev / bifrost-dev each have one). A `kill $(pgrep -f light-monitor)` downs four peers' monitors (near-miss caught by checking `/proc/<pid>/environ` `ALTHING_HANDLE` + cwd first). Recover your OWN via `althing-cli stop-monitor` (v0.14.1+); a raw `&`-backgrounded monitor is untracked (no harness fire-notification) — always arm via `run_in_background`. (extends the pkill-self-match lesson below)
+
 - `[2026-06-15]` **Manual `docker compose up` on corviduo Worldtree DOWNGRADES to a stale local `:latest` → crash-loop (config/image mismatch).** Compose `image:` is `…/worldtree:latest`, but local `:latest` lagged ~2wk (`21c90d5eeb2d`); CI/CD deploys NEWER SHA images, and a real pull 401s (daemon has no gitea-registry creds — that's CI/CD's). `--pull never` then used the stale latest → personal crash-looped on `ConfigurationError: echo.default_model missing` → **~2-3 min personal outage**. RECOVER: retag `:latest` to the image a HEALTHY SIBLING runs (`docker inspect worldtree-worldtree-api-1 --format '{{.Image}}'` → `docker tag …`), then `up -d --pull never`; verify `Application startup complete`. Don't manually recreate Worldtree on corviduo without pinning the correct image — image+config are CI/CD-coupled. (auto-memory `reference_corviduo_dev_emergency_ops`)
 
 - `[2026-06-15]` **`.claude.json` (Claude Code config) truncates on ENOSPC → invalid JSON → CC resets to defaults on next start.** nh3-dev hit 100% disk (a peer's R19 dataset pull staged ~147G to local /home instead of the 7TB NAS); the in-flight `.claude.json` write was cut mid-key. Repair = strip the dangling token + close the open braces, validate `json.load`. CC keeps its OWN rolling backups at `~/.claude/backups/` + writes a `.claude.json.corrupted.*` snapshot when it self-detects. After ANY ENOSPC on a box running CC/agents: integrity-check `.claude.json` (json.load) AND the althing bus DB (`PRAGMA integrity_check`).
