Grouping proposals remain separate from the published source.
Canonmap can propose reporting groups and lower-level distinctions for a named goal. Adoption is explicit; no recommendation silently changes normalization.
Production decisions identify an immutable mapping build.
The public demonstration serves an explicitly selected calibrated build. Normalize and Performance identify the exact mapping build and evaluation evidence used for requests.
