Sweep collisions
Read the execution contract before starting. Validate the final receipt with its parameterized verification.argv, replacing {python}, {skill_dir}, and {receipt} with concrete local values.
Before editing a contested seam, search the repository, recent branches or reviews available in scope, and deployment or scheduled automation that can write the same surface.
Return a receipt with the queried sources, exact search terms, time boundary,
overlapping owners, conflicting contracts, and CLEAR, COORDINATE, or
BLOCKED. Label unavailable sources UNVERIFIED; absence of access is not a
clear result.
Use connectors only when already authorized. Never broaden a repository task into messages, tickets, or remote changes without explicit authority.
