Proof Ledger - live aggregate

The Proof Ledger

Aggregate outcomes from 27 measured prompts: fixes shipped, the exact prompts re-tested on a schedule, and movement recorded against each prompt's own pre-ship baseline.

Across reportable wins

Pathway split across reportable wins: 5 fast retrieval (within 3 days), 5 slow training-cycle (14+ days), 2 in between. Observed-but-not-yet-reportable wins: 0.

Of 12 reportable win(s), 8 held across repeat tests - the brand stayed cited in a majority of runs after first appearing.

Segment breakdowns

Each segment publishes independently once it clears its own floor (8 measured, 3 reportable wins). Segments below that stay in collection.

By prompt class
What counts as a win

A tracked prompt counts as an observed win when the exact prompt - re-run on a schedule after a fix shipped - returns at least one citation of the tracked brand. It only graduates to a reportable win when sampling reaches medium confidence (at least 3 post-ship runs) and the post-ship citation rate beats that prompt's own pre-ship baseline.

Pathway definitions

First citation within 3 days of shipping is classed as a fast retrieval (RAG) effect; 14 days or later is classed as a slow training-cycle effect; in between is recorded as unknown.
