The gpu lane is now a NODE POOL (this Mac + remote workers from nodes.json) instead
of a single-Metal semaphore. A gpu job runs on whichever node is free:
- server/remote.py: ssh+rsync dispatch — mkdir remote dirs, rsync inputs out, run
the operator's run.py over ssh with repo-relative paths (HF_TOKEN sourced from the
node's .env.remote, off the process table), rsync outputs back, clean up. Cached
health checks; per-node operator allowlist.
- runner: _acquire_gpu_node picks the first free node that supports the op (local
runs anything; a remote must list it + be reachable → auto-fallback to local).
_run_job branches local/remote; the M1 never touches the M3's DB.
- sysinfo/Dashboard: gpu lane limit = pool size; per-node status cards.
- nodes.json (gitignored, primary-only): M1 worker, allowlist excludes trellis_mac
(bf16 unverified on M1) + brush_train (not installed there).
Verified: two FLUX jobs from one queue split M3(local, 10.3s) + M1(remote via ssh,
21.2s), both images rsync'd back and registered on the M3.

- flux_local: prompt->image fully on-device via mflux (schnell/dev, steps,
quantize, seed, size). Both FLUX repos are HF-gated as of 2026-07 (schnell
included) — clean GatedRepoError surfaces with a hint; needs owner HF token.
- openrouter_image: prompt->image via OpenRouter chat/completions with
modalities [image,text]; parses data-URL images from the response; model
picker for nano-banana / nano-banana-pro. Gated on OPENROUTER_API_KEY.
- settings: openrouter_key added to vault (masked/redacted/env-injected)
- scripts/install_mflux.sh; venv installed
- A/B flow: run both with the same prompt, judge in Compare mode

Operators (16 total):
- fal_hunyuan3d_v21: Hunyuan3D 2.1 single-image (live-verified dash variant,
~90s; v21 multi-view is broken on fal — v2 stays the multi-view path)
- fal_bg_remove (BiRefNet v2): subject cutout pre-pass — the biggest quality
lever before image->3D
- fal_upscale (SeedVR faithful upscale), fal_image_edit (nano-banana prompt
edits), fal_text_image (Ideogram v3 — first no-input operator)
- fal_common: collect='images' mode; recursive URL extractor now takes the
wanted extension set
UI: operator dropdown grouped by category (optgroup); operators with
accepts: [] run without a selected asset ('No input asset needed' note);
run-button/launch logic updated accordingly.
Review fixes (Opus Phase 1 commit):
- runner._run_lane crashed (TypeError) when a queued job was deleted before
the worker picked it up
- PUT /api/settings treated empty string as a masked placeholder, making
secrets impossible to clear from the UI
- store.register_file mutated the caller's meta dict via pop
