Independent replication
A separately attributed run of a referenced protocol.
REPLICATION INDEX · P09
An empty result is still part of the map.
This index will make independent repetitions, nulls, failures, and non-comparable runs discoverable without turning counts into consensus or erasing differences in conditions.
Negative result
The anticipated observation did not occur within declared conditions.
Failed replication
A method was attempted but could not reproduce the reported finding.
Non-comparable
Differences in detector, frame, method, or scale block a defensible comparison.
ADMISSION GATE
What a record must preserve
- Immutable contribution and parent-protocol identifiers.
- A statement of investigator and institutional independence.
- Method deviations, detector, frame, and relevant scale.
- Raw evidence references and result classification.
- Review status that may change only through appended history.
