Every numeric or capability claim should carry an evidence class:

Class	Meaning
SOURCE	Taken from an authoritative source (model card, GGUF metadata, GPU spec, docs).
CALCULATED	Deterministically derived from source values with a documented formula.
ESTIMATED	Informed range or approximation (for example runtime overhead).
POLICY	Site rule or safety threshold (for example weights-only band edges).
OBSERVED	Measured in a controlled or legacy run.
COMMUNITY	External report; not ground truth by itself.

Pages today primarily use SOURCE, POLICY, and optionally OBSERVED (methodology-v0).

Weights-only bands are not full fit or KV totals. Do not treat them as calculated fit results.
