## Abstract

A stewardship instrument for maintained commitments: systems, obligations, and relationships to past work. It reads a declared file of commitments against a versioned registry and returns a fail-closed declaration-coverage verdict (MAINTAINED, NEEDS_ATTENTION, STALE, OUTSIDE_SCOPE) over the care signals each commitment requires. It measures whether the care a steward declared was fresh at the review date — never whether the care happened; a MAINTAINED verdict is not a warranty, SLA, availability guarantee, or proof of maintenance, and it never authorizes an action.
