What

Follow-up to #133, completing the requested laguna-s@2bit live test — and it passed the promotion gate:

model codegen bugfix edit json avg tok/s
laguna-s@2bit PASS PASS PASS PASS 5.4

That makes laguna-s the second 4/4 model (alongside coder-32b) and confirms the serving hypothesis from #133's failure analysis: the MoE path works exactly when the weights fit wired GPU memory (~72% of RAM). 2bit = 35GB fits a 64GB Mac's ~46GB wired limit and generates cleanly; 3bit = 51.5GB exceeds it and stalls to ~0 tok/s.

Changes

  • laguna-s returns to the head of the auto ladder — a 64GB machine's /team delegate local now provisions the bench-proven laguna-s@2bit.
  • Quant floors now encode the verified wired-memory rule (2bit@64GB, 3/4bit@96GB, 6bit@192GB, 8bit@256GB), so no RAM tier can resolve to a quant that would repeat the 3bit stall.
  • New test pins the rule: laguna_floors_keep_weights_inside_wired_gpu_memory asserts 3bit can never resolve on 64GB.
  • nemotron-30b (1/4 on bench) and qwen3.6-35b (nvfp4 unsupported) stay explicit-only.

Tests

1,573/1,574 across hi-agent / hi-tools / hi / hi-tui (the one failure is the documented load-flaky dependent_task_waits_for_success in an untouched subsystem; passes in isolation).

…bit, floors encode the wired-memory rule

The user-requested laguna-s@2bit live test confirmed the serving hypothesis
and passed the promotion gate: 35GB of 2bit weights fit inside the ~72%-of-RAM
wired GPU limit on a 64GB Mac and score 4/4 on team-bench at 5.4 tok/s
(codegen/bugfix/edit compiled + asserted, strict JSON), while 3bit (51.5GB)
exceeds that limit and stalls to ~0 tok/s in the MoE expert path.

laguna-s therefore returns to the head of the auto ladder with quant floors
raised to keep every rung GPU-resident (2bit@64, 3/4bit@96, 6bit@192,
8bit@256): auto on a 64GB machine now provisions the bench-proven
laguna-s@2bit, and no tier can resolve to a quant that would repeat the
3bit stall. nemotron-30b (1/4) and qwen3.6-35b (nvfp4 unsupported) stay
explicit-only.
