Evidence-Gated Product Data Extraction

Specledger running: Evidence-Gated Product Data Extraction.

Captured from the live deployment, not a mockup

01 · The problem

An LLM's self-reported confidence is not a probability, so it cannot decide what auto-publishes. Replaced it with a logistic calibrator over 11 evidence features fitted on held-out data, choosing the threshold to hit a measured precision floor.

02 · How it works

  • 01

    Traded auto-publish rate for correctness deliberately: publishing 80% instead of 100% moved precision on published values from 69.2% to 98.7%, safety-critical precision from 81.3% to 100%, and wrong values published from 28 to 1.

  • 02

    Kept the pipeline fully working with the LLM switched off, proving the model adds recall without being load-bearing for correctness.

  • 03

    Replaced an LLM's self-reported confidence with a logistic calibrator over 11 evidence features fitted on held-out data, picking the auto-publish threshold to meet a stated precision floor.

03 · What it cost, and what it returned

Publishing 80% rather than 100% moved precision on published values from 69.2% to 98.7% and cut wrong values published from 28 to 1, with safety-critical precision reaching 100%.
