Hollow

Maintenance release. No new agent-facing features — onboarding accuracy, Linux portability, and a few latent bugs from the 35B model swap.

Fixes

Smaller-model regression (latent since v5.7.0). When the model swap to qwen3.6:35b-a3b landed, four hardcoded routing tables were left pointing at the 35B model regardless of what the user actually picked in the setup wizard:

• agents/model_manager.COMPLEXITY_MODEL
• agents/scheduler.ROLE_MODEL
• agents/adaptive_router static defaults
• api/server.MODEL_ROUTES

A user picking llama3.2:3b or gemma3:4b in the wizard would have the scheduler route through a model they never pulled. All four now resolve from cfg.ollama.default_model at import. The VRAM fallback table also picked up rows for the 9B / 4B / 3B options.

Linux Docker compose portability. Two issues hit external Linux users:

• host.docker.internal resolves automatically on Docker Desktop (Windows/macOS) but not on native Linux Docker. Added extra_hosts: host.docker.internal:host-gateway to the api and store services. Harmless on Win/Mac.
• The setup wizard's GPU fallback now detects the specific could not select device driver "nvidia" error and prints an nvidia-container-toolkit install hint when falling back to CPU-only mode. The CUDA toolkit alone is not enough — Docker needs a separate package, which was a common confusion.

Ghost tools (#15). tools/dynamic/ could accumulate JSON specs whose paired .py implementation was missing — agents would see them in capability listings, call them, get null back, and burn cycles investigating. The 5-cycle dynamic-tool retire block in daemon.py now sweeps orphan JSON specs alongside its existing broken-tool cleanup.

Docs

README rewritten against the actual 5.7.x system:

• Default model VRAM requirement corrected (was 8GB+, actually 24GB+ for the default 35B). All four wizard options now shown in a table so users can pick honestly.
• Capability count corrected (21 → ~30).
• New Linux setup section covering Docker Desktop file sharing (#17) and nvidia-container-toolkit (#18).
• Sections added for the five-layer false-completion gate, mechanical capability gating, and the lessons system — these were the headline 5.6.x and 5.7.x changes.

CI

New docker-smoke-test job: stock Ubuntu runner, no GPU, no Ollama. Builds the image locally, brings the stack up, waits for /health, hits the dashboard, tears down. The smallest test that would have caught the compose issues that hit external users before release.

Issues addressed

• Closes #15 (ghost tools)
• #13 (skipped_agents drain) — confirmed already fixed in code, closed
• #17, #18 — README + wizard fixes; reporters can retest
