ASSAY-001

A pre-registered, independently rescored audit of Jev's calibration and type safety: calibrated on CLINC150 (ECE 0.0204), systematically overconfident on Banking77 (ECE 0.0936), and zero type errors across 8,576 responses.

About this project

Verdict: on CLINC150, Jev's chosen-option probabilities were calibrated (ECE 0.0204); on Banking77 they were not (ECE 0.0936, systematically overconfident). Across 8,576 responses there were zero type errors. Full write-up: PROTOCOL.md — frozen 2026-09-17 before any query (FREEZE.sha256). AMENDMENT-1.md (before the run), Amendment 2 (after, in REPORT.md).

Quoted from the project's README. Read the full README.

Highlights

  • On CLINC150 Jev's chosen-option probabilities were calibrated at ECE 0.0204; on Banking77 they were not, at ECE 0.0936 and systematically overconfident.
  • Across 8,576 responses there were zero type errors.
  • The protocol was frozen on 2026-09-17 before any query, with corpus hashes for Banking77 and CLINC150 sealed before the first API call.
  • Every request and response is logged verbatim and sealed with SHA-256; smoke-test connectivity runs are excluded from scoring.
  • A blind independent re-score written from a spec on a different base model matched every field of the original scoring.

Quickstart

bash
python3 harness/controls.py
python3 harness/score.py banking77 --sum-tol 0.02
python3 harness/score.py clinc150 --sum-tol 0.02

Watch out

No license file, so reuse terms are unclear; re-running the model needs a TypeSafe key at ~/.config/typesafe/api_key and produces a new run, not the recorded one.
