Confidence is a model input, not a calibrated probability. Current configuration weights do not establish historical weights. C4 is disclosed as frozen; no past score is changed.

Excerpt corrections and quality flags

Original excerpts and their hashes are never edited; a corrected display excerpt is a separate annotation with its own digest and date. Detector hits stay SUSPECTED until verified against the primary document.

Research interpretation and limits

In the 90 days ending 2026-10-14T20:45:20.832379-06:00: 6 event objects from 6 distinct accessions; 0 objects lack an accession. These are descriptive counts, not independent observations.

Composite reconstruction: RECONCILED. Confidence inputs are not calibrated probabilities. Current weights alone cannot establish historical contributions. C4 remains disclosed as frozen from 2026-05-18.

source_hash identifies the original stored event record; it is not a digest of the displayed excerpt or the original SEC file. Public event inclusion verification: NOT_AVAILABLE. /evidence/verify.json describes SIGNAL snapshot ledger checks and does not authenticate this event hash. Quote occurrence, semantic support, arithmetic and external provenance are separate checks.
