short_description: Elastic per-block level-set quantization, measured

DMCRA Lab — elastic per-block level sets, measured on real weights

A client-side lab for the Dynamic Multi-Centroid Routing Architecture idea: instead of a fixed ternary grid {-1,0,+1} on every weight, let the codebook itself be chosen per block from a nested family ({+-1} → {0,+-1} → {0,+-1,+-2} → …) under a bit budget. It runs the real llama forward pass over the real weight bytes of a real GGUF, in your browser, and reports what each choice costs.

No server, no GPU, no upload, no CDN, no build step. Every figure is measured on your machine.

What it measures

1. The level-set ladder — binary, quad, ternary, penta, hepta, oct, nona, each run through the real pass. Reported: the pass's own measured bits/weight, reconstruction RMSE, the mean rank of the true next token, top-1, and Spearman rho of all 512 logits against the exact pass.
2. The multi-channel zero — {0} vs the document's {0/0/0}, compared logit by logit for exact equality. Reported whichever way it comes out.
3. Elastic allocation at equal bits — a per-block plan that unclamps the most important blocks to the 3-bit grid and clamps the least important to the 1-bit grid, held to exactly 2.0000 index bits per weight, measured against uniform ternary at the same budget. The panel prints UNDECIDED when the difference is smaller than the run can resolve.

Verdicts (Node suite, 89 scored positions)

claim	measured
elastic unclamping beats uniform spending at equal bits	not supported — every keyed plan was worse (+46 to +147 rank positions, |t| 3.2-5.8)
the keys still matter	supported — keyed plans scored rho 0.52-0.55 against a key-free control's 0.06
{0/0/0} is an information channel	refuted exactly — bit-identical logits, an extra index bit charged
the zero-free grid at equal bits (quad)	supported — rho 0.8659 vs ternary's 0.8359 at the same 2 index bits
per-block least-squares scales	the largest effect found — ternary rho 0.5248 → 0.8359

Verified

25 quantiser assertions (including that this project's ternary reproduces the sibling project's already-verified toTernary exactly), 21 end-to-end forward-pass assertions, and 22 assertions driving this exact page through a stubbed DOM — refusing an over-ceiling model, refusing an empty prompt, and reporting an under-powered comparison as undecided rather than as a result.
