Historical Calibration
Retrospective cases test whether the Ledger method would have separated a catalyst narrative from its later commercial evidence.
Calibration boundary
Retrospective, not prospective research.
These cases are constructed after relevant outcomes were already observable. They are method calibration, not contemporaneous forecasts, and they must not be interpreted as evidence of live predictive performance.
Historical Calibration is not a development archive. It is a separate retrospective record and is not a substitute for the time-stamped prospective thesis archive used to judge live research.
No historical case enters the prospective Outcome Ledger. Only theses with a time-stamped, forward-locked question, catalyst set and measurement standard can contribute to that record.
Publication gate
A case appears only when the record can be audited.
What was knowable before the outcome is kept separate from what became visible afterward.
Material changes remain visible rather than being silently rewritten into the case.
Calibration library
Historical cases are available with Professional access.
The methodology boundary remains public. Completed retrospective case records are reserved for Professional, Business and Enterprise access.
