Kind: kernel-term
Status: checked

Evidence notes

Derived from a clean-commit typed execution receipt. The registered fact-operation checker replays the resolved multi-target statement adapter and candidate manifests through the operation's own reviewed checker module and requires the exact kernel-checked proof, dependency-free result, and matching target definition; no caller-authored route, footprint, checker, or shell command is accepted.
