@uvrn/track-record

Per-origin track records: transcription fidelity, revision counts, and Brier-scored forecast resolution.

These are observations about past agreement and resolution — not honesty verdicts. They must never enter a hashed receipt.

Install

pnpm add @uvrn/track-record

Offline default

import {
  InMemoryTrackRecordStore,
  buildForecastResolution,
  isFaithfulTranscription,
  formatTrackRecordObservation,
} from '@uvrn/track-record';

const store = new InMemoryTrackRecordStore();

await store.addTranscription({
  originId: 'origin:example',
  sampleId: 's1',
  observedAt: new Date().toISOString(),
  faithful: isFaithfulTranscription(100, 100),
  originValue: 100,
  restatedValue: 100,
});

const record = await store.getRecord('origin:example');
console.log(formatTrackRecordObservation(record!));

Learned credibility (opt-in)

getLearnedCredibility / deriveLearnedCredibility return a [0,1] observation score when data exists. Consensus consumption is off by default — callers opt in and must report both declared and learned numbers.
