Conflicting chain-of-custody histories detected

Two internally coherent custody histories described incompatible preservation paths for the same evidentiary object. The architecture preserved the conflict instead of selecting a preferred history.

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.
