5 / 5
Produced useful evidence-bounded transition records.
Gate 0 closed · evidence record
Monopolises tested whether a single strategic Replacement Horizon could be reconstructed reproducibly from public primary evidence across five fixed cases. It could not.
Evidence before category means stopping when the metric does not survive.
What was tested
This was the v0.1 proposition. It remains part of the research record, but Gate 0 did not validate Replacement Horizon as the primary scalable measurement.
Fixed-set result
Produced useful evidence-bounded transition records.
Produced a canonical strategic Replacement Horizon without unresolved methodological choice.
The fixed set was closed without adding a sixth case.
Governance outcome
The case records remain valid research artifacts. Their recurring distinctions are findings, not a successor category.
No global replacement graph, scores, rankings, or scaled entity pages are authorized by the failed Gate.
