This file is byte-identical to the first copy the registry indexed, one of 3 copies on public GitHub. Same content hash, same audit grade.
DESIGN.md@design-systems/library/posthog is agent-read markdown (design) from plugin87/ux-ui-agent-skills.
Indexed from public GitHub and served as immutable, content-addressed versions.
