Keep evidence private.
Submit an opaque SHA-256 commitment—not prompts, spans, files, or customer identifiers.

Evidence
designed to
endure.
Portable, cryptographically signed receipts for evidence chains that must survive beyond the system that created them.

The protocol / 002
A durable proof,
made in three moves.
TraceLogica stays deliberately narrow. Your system keeps its data. The authority receives only the commitment required to issue a portable receipt.
Anchor its position.
The authority appends the checkpoint and signs its sequence, time, key, account, and predecessor.
Take the proof with you.
Retain the receipt and public-key document. Verify offline, independent of the original application.
A receipt you can read / 003
Integrity,
made visible.
Every field is bound by one signature. Change a byte and verification fails.

Honest assurance / 004
Strong claims.
Precise boundaries.
Independent verification is valuable only when the claim is exact. We state what a valid receipt demonstrates—and what it cannot.
