When ON, paper-fibre microstructure is folded into the KDF — closes the perfect-photocopy attack.

Issue with Sparse-Blank Encoding

~64 key-derived gaps per counterparty + ~120 decoy defects, camouflaged as printer artefacts.

Verifying Counterparty — select counterparty — Verify Document

Recomputes expected gap positions from secret + doc hash (+ fibre print if enabled) and tests pixel-level presence at each.

Attack Simulation

Photocopy = JPEG smear. Pristine = perfect xerographic copy (passes without fibre upgrade — known limitation). Forger = random gaps.
