Detailed Description

Per-source-address authentication lockout (PROTOCORE_ENABLE_AUTH_LOCKOUT).

A small fixed table of buckets, one per recently-seen source address: consecutive failures escalate a lockout, a success clears it, and the least recently used bucket is evicted when the table is full. The window arithmetic is unsigned throughout, so a millisecond-counter rollover cannot unlock an address early or lock one out forever.
