LTMi-XT v0.1 specification

The open retrieval format: single-claim loci, a four-level breadcrumb, BLAKE2b lattice coordinates, byte-offset provenance, horizon and decay, with the TypeScript reference implementation.

XE5: memory-conditioned specialist mixing

A 147.5M model trained from scratch in which specialists are combined by a learned composer rather than selected by a gate, with the weights conditioned on where a descent through runtime-written memory terminates. A mixture of experts computes w = gate(x); XE5 computes w = compose(x, m), so fixing the input does not fix the weights.

XE4-S: dense composition after a routing collapse

The previous architecture selected among specialists and collapsed past N = 3: top-1 route accuracy fell from 100% at N = 2 to 23.3%, a learned replacement router carried exactly 0.0 bits of mutual information, and enlarging one corpus twentyfold made things worse. This is what was built instead.

Anchor-token masking, paper

Three masking objectives compared on identical data. Anchor-token masking gives a 1.67× held-out advantage over random-position masking with a 95% interval of [1.51, 1.85]; four mechanism probes end in a V/O ablation. Deposited on Zenodo under DOI 10.5281/zenodo.20496783, CC-BY-4.0.

Anchor-token masking, technical report

The report form of the same study: setup, raw measurement tables, the reverse-asymmetric control, attention and weight-allocation probes, and the reproduction recipe.
