Defined in:

Overview

Error raised when a downloaded resource fails integrity verification (SHA-256 mismatch against manifest, truncated content, etc.).

The downloaded bytes are never trusted until verified against a known manifest entry. Mismatch raises this error with both hashes so the caller can surface them in audit logs and CI output.
