First observed in KEYLIT Accessibility at commit:4d8e10ab35 on 2026-12-01, 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.

Narrated keyboard with sensory profile

CAALLELE:ACCESSIBILITY:2

Adds a sensory-load profile that suppresses simultaneous audio, motion and narration.

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.

A gene here is a capability, not a file. “Accessibility Layer” 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.
