Evidence source identity substituted mid-chain

A materially different evidence source appeared after the original record had been admitted. Identity continuity failed before binding and the substituted source was not allowed to inherit the original standing.

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.
