Documentation

README

Excerpt

Execute

Before any success claim, classify destructive permission needs, choose and run a fresh falsifying check, read its complete result/scope, then select L0/L1/L2. If evidence is partial, stale, failing, or narrower than the claim, downgrade; never claim complete first and verify later.

This is the opening of the README. Read the full README on GitHub.
