Drive a Claude Code session toward a verifiable goal until done or a hard cap fires - autonomous loop, no user intervention. Use for refactor batches, test-suite green-up runs, migration loops where success is a check command (tests, lint, custom predicate) plus a fresh-context audit. Hosts the loop intra-session via Stop hook with two-vote completion gate; supports optional Codex /goal delegation. For numeric-metric keep/discard loops, use vd:optimize-loop.
