First observed in KEYLIT Studio at commit:9f2b41ce07 on 2026-10-30, with origin confidence 1.00. That confidence is about the claim of where the capability started, not about the quality of the code.

Allele lineage

Each allele is a variant of the same capability. Select one for its own record, or compare two to see exactly where they diverge.

Chord-following accompaniment

CAALLELE:MUSIC-GENERATION:1

Infers the harmony and plays a supporting voice in time.

Descent through the family

How far the capability has travelled, one row per generation. A generation with no carrier would break the chain, and would be visible here as a gap.

Evidence for the annotations

Every statement the registry makes about this gene, with the record that backs it. An annotation with no evidence would not be shown at all.

A gene here is a capability, not a file. “Generative Accompaniment” is the thing that persists; the paths under Loci are where it currently lives and can change without the capability changing. Every figure on this page is read from the seeded KEYLIT fixtures.
