A feature specification defines scope boundaries by explicitly documenting Problem, Scope, and Non-Goals sections, preventing accidental expansion into adjacent surfaces and locking in contract clarity for runtime and protocol behavior.

A validation matrix in feature specification is a concrete mapping of contract expectations to actual verification checks like tests, snapshots, and typecheck gates, ensuring the documented runtime and protocol contracts are validation-ready.

You maintain stable technical contracts for TUI and protocol features by authoring canonical feature specs under a dedicated docs directory that follow structured spec surface rules, acting as the durable source of truth for behavior boundaries.

You should not include implementation evidence or rollout journals in a feature spec; instead, compact stable conclusions into the spec and direct implementation evidence to journals and follow-up tasks to avoid mixing documentation types.

You need to update canonical feature specification docs when creating, revising, or reviewing feature contract documents that define architecture and validation expectations, ensuring TUI and protocol contracts remain consistent over time.
