Evidence notes

Derived from a clean-commit typed execution receipt. The registered fact-operation checker replays the immutable source-bound dependency theorem receipt and requires its exact two-fresh-kernel proof, empty axiom footprint, eight named direct premise identities, and replay-bound transitive dependency digest; no caller-authored route, footprint, checker, or shell command is accepted.
