Historical artifact cannot be cryptographically reconstructed

A historical artifact remained human-readable but could not be reproduced to its preserved cryptographic commitment from the admitted package. Reliance was withheld instead of treating readability as integrity proof.

EXECUTABLE ARTIFACT · INSPECT THE PROOF

This is the artifact itself.

The determination below is generated by executing the frozen specification through the TA-14 eight-stage harness. The specification, predicates, trace, receipt, manifest and package root are exposed here for inspection and reproduction.
