challenge

Adversarial verification protocol for claims, plans, and root causes -- refute by default, fresh-context intake, sources-backed, bounded rounds. Runs SYSTEMATICALLY, by claim TYPE (not a stakes judgment), before reporting to the owner any of: a root-cause conclusion, a done/verified claim, an irreversible action (commit/deploy/rm/push), or a 2nd-time fix -- WHETHER inside an APEX task OR in plain conversation. Also runs systematically at every APEX eLicit round and every Verify gate, exactly like sniper runs systematically at eXamine, NO EXCEPTIONS. Do NOT use for: code correctness/lint/type validation (use code-quality/sniper).
