Genesis Recovery

A complete copy should mean a complete copy.

GENESIS / RECEIVED COPY01 / 04

Trusted baseline

1 → TONY   2 → IS   3 → SAFE

Each received piece is compared with a SHA-256 fingerprint of this separate baseline. Duplicates do not fill a missing slot.

Trust the check.
Not the green light.

A copy can be damaged, incomplete, shuffled or duplicated. Test it before releasing it. Retry replaces the received data with a clean local copy.

Investigate the first copy.

What counts as complete?

All three distinct piece numbers must match their trusted fingerprints. Two copies of piece 1 still leave piece 2 missing. A shuffled copy can be complete.
