Evidence-gated cleanup after WAR work lands — delete stray WAR branches, reap orphaned run worktrees, close done bookkeeping issues and survey-swept issues, each only behind a checkable evidence chain with git as the source of truth; --scorched-earth widens to every local branch and worktree behind a non-negotiable protected core. Explicitly-invoked-only (a deleting verb must never fire because a sentence pattern-matched); never auto-triggers.
