C.17:8.1 - Cross-scale and cross-source limits

When a reading moves across scales, state which Characteristics are preserved, aggregated, projected, or lost and cite the actual aggregation, projection, transition, temporal cross-scale, or Bridge relation on which the reading depends. Keep a plain distortion note next to the projection. If the receiving use needs the named A.0 qualifier structure, use A.0:QF.2a and its optional OutcomeMapRef, TransitionRelationRef, or BridgeDistortionNote; otherwise the plain loss statement is enough.

Different projections of the same retained set or frontier may preserve different information. A useful projection is not automatically information-preserving, and one atlas-like view does not cancel the original Front, Archive, or result.

When claims come from different source schemes or corpora, do not compare by matching labels. State the actual mapping, Bridge when required, direction, loss, calibration, and receiving use. A target-use pilot may improve evidence for that use; it does not make the source and target bases identical.
