Detailed Description

One lock-free terminal record per 8259 input.

A line which still owes EOI cannot deliver another occurrence. A line acknowledged before its hard stage still cannot produce a second rich tail while the first is pending: its next entry sees controller ownership and is reduced to the counted fail-closed path. The caller keeps that counted path as an overflow fallback rather than waiting here.
