The current authoritative source explicitly supports the statement.
03 / EVIDENCE
We would rather publish uncertainty than hide it behind a score.
Every platform statement should show where it came from, when it was checked and how directly it supports the model.
CCFP normalized two or more directly documented structures into one canonical concept.
A reasoned CCFP interpretation, clearly distinguished from platform documentation.
Documented, but the capability or contract is new or expected to change.
The available evidence is insufficient; CCFP publishes the uncertainty.

METHOD / SIX STEPS
01
Capture the current authoritative source.
02
Record field, scope and conditionality.
03
Map without erasing semantic differences.
04
Assign an explicit evidence status.
05
Add only deterministic tests.
06
Bind results to the versions used.
SYNTHETIC TESTING / NOT REAL-BRAND EVIDENCE
Invented catalogues. Inspectable expectations.
6 of 6 authored catalogue cases matched their declared expectations. 0 false FAIL files among 4 deliberately clean or warning-only fixtures. This small, authored set is not a general accuracy estimate or merchant usability study.
