§22.8 Escalation EMIT/HALT

When the gate fires escalate, the run halts immediately. Remaining steps are marked skipped_by_escalation (distinct from skipped_by_gate). An open escalation record is emitted with a deterministic record_hash over { decision, halted_steps }; opened_at is excluded from the preimage so the hash is stable across runs. The composite execution hash is computed over ran steps only, before the escalation record is attached.
