SOLID

Enforce cohesive responsibilities, safe extension, substitutable contracts,
consumer-sized interfaces, and inward dependency direction with the same strict evidence
standard as dry.

Consume the current consumers retained by yagni and the authority map selected by
ssot. Emit only the responsibility, contract, and dependency boundary needed for
implementation; accept one recheck after dry. The global order is owned by
search-first. Read the SOLID remediation procedure (skill file) for confirmed
violations.

SOLID is not permission to add interfaces, inheritance, factories, plugins, or layers
speculatively. A small cohesive function with no architectural boundary needs only
inline simplify. Missing consumers, contracts, or runtime evidence blocks redesign
rather than authorizing pattern cargo cult.
