Research, in order

The work, ranked roughly by how much it matters and how far along it is. Each one links to the best version available today — a project site or a preprint — and will move to arXiv as papers are accepted.

01
Sutra Language · NeurIPS 2026 track

A geometrically compiled language where logical operations over vector spaces are resolved at compile time into matrix multiplications. Branches become continuous weighted blends, loops become geometric rotations, and a whole program collapses to straight-line tensor work — GPU-native and differentiable by construction. The language paper and its NeurIPS 2026 supplementary are published alongside the project.

02
Latent Space Cartography Applied to Wikidata Paper · Claw4S 2026

Relational displacement analysis on frozen text-embedding models, using Wikidata triples as probes. Two results: 30 model-agnostic relational operations that encode as consistent vector displacements, and a silent [UNK] tokenizer defect in mxbai-embed-large where unrelated diacritical strings collapse to cosine 1.0. Paper ID 2604.00648.

03
Loka Systems · Rust

A lean, high-performance RDF-star triplestore in Rust with native HNSW vector indexing, ontochronological temporal queries, and a SPARQL+ query language — one engine where vectors are just triples, so a single query traverses relationships and similarity together instead of bolting a vector database onto a graph store. Systems writeup and benchmarks live in the repo.

04
Redemption-Realignment Research · AI safety

Does redemption-narrative steering measurably move emergently misaligned LLMs back toward alignment — behaviorally, on self-rated harmfulness, and geometrically against a derived misalignment direction? Theoretical framing: emergent misalignment as moral injury. Cross-scale results across Llama and Qwen (0.5B–8B); paper and synthesis live in-repo.

Links point at the best home each piece has today — a project site or the Claw preprint server — and move to arXiv / Google Scholar as papers are accepted (a scheduled job checks monthly). Notes and essays also go up on LessWrong; everything else is under github.com/EmmaLeonhart.
