Automated README summary
Automatically summarized from the README on 19 Oct 2026; not a run by jevbooks. Run instructions and author-reported outcomes still need verification.
What it is
Tachyone is a self-hosted decision engine for developers who need fast, calibrated atomic judgments instead of generated text. It answers choice, score and noul questions over a given state, and is a drop-in replacement for the Jev /v1/systemone wire contract.
How it uses Jev
Tachyone implements the Jev /v1/systemone protocol: a client sends a state plus typed questions (choice, score, noul) and receives typed answers with probabilities and calibrated confidence. The local encoder backend runs one non-autoregressive forward pass (ModernBERT/mmBERT plus LoRA adapters) to produce those decisions.
Primitives:choicescorenoul
Technique worth stealing
Non-autoregressive single forward pass with strictly proper scoring (RLCD) and per-(primitive, language) temperature calibration.

Model judgments from README excerpts
Project signals use repository metadata, an existing summary and the first 700 README characters, not the full project. “Not found” means not detected in that material; it does not establish absence. These are the original judgments with recorded models and dates, not source audits or run results.

Evidence
These signals use repository metadata, an existing summary and at most 700 cleaned README characters. ≥ 0.60 means reported in that excerpt; ≤ 0.40 means not found there. The middle band is inconclusive. None is a source-code audit or a test result. The runnable-tool question excludes research experiments; the recommendation question asks for a learning shortlist, not a quality verdict.
