Constraint-first reconstruction. Bound the event, use the known fully, name leftover gaps, propose a hypothesis only there. Use when someone wants a cause, a villain, a theory, a postmortem, or "what happened" for something they did not get to rerun. Protocol requests: /bound /hoop /gap /reopen /full (natural-language equivalents work). Not for proofs, controlled experiments, or OODA-time action against an opponent.
