Gate 0 · closed · FAIL
Replacement Horizon did not survive the first evidence gate.
Five fixed cases produced reconstructable transition records, but none produced a single canonical strategic Replacement Horizon without unresolved methodological choice.
Fixed result
5/5 useful records. 0/5 canonical strategic intervals.
Construction consequence
No replacement graph, score, ranking, scaled entity pages, or ratified standard is authorized by this Gate.
Research integrity
The failed thesis and five cases remain as provenance. No sixth case was added to rescue the result.
