Capability Matrix

This repo deliberately separates four layers.

Layer	Meaning	Proven Here	Not Proven Here
Method contract	the accepted public mechanism	frozen parent boundary, routed family-local repair, trunk block semantics, promotion contract	private discovery pipeline, full training moat
Experiment bundle	replayable evidence for the current surface	exact no-trunk ablation, same-parent slices, paired replay stats, locality probes	complete classic PEFT comparator coverage, full ablation grid
Audit boundary	trust and negative evidence	no obvious text overlap, external non-regression, holdout2, release-boundary disclosure	broad unseen-family generalization or broad reasoning transfer
Board artifact	derived ESP32-C3 proof	flash-resident fixed-batch execution, raw board readback, exact host-full alignment	unrestricted open-input MCU inference

Board Layer

• aggregate board-proof mode: logiqa_batch_compiled_probe_aggregated
• default single-batch board readback mode: logiqa_batch_compiled_probe
• compiled probe mode: host_full_exact
• board proof result: 249 / 642 = 0.3878504672897196
• host_full_match = 642

How To Read This Correctly

The strongest honest claim is:

• a task-specialized accepted surface can be audited and materially improved over its frozen parent
• that surface can be crystallized into a bounded board artifact
• the public evidence is meaningful but explicitly bounded

The repo does not claim that these four layers are identical.
