> XMSS, XMSSMT, LMS, and HSS are stateful hash-based signature schemes with a finite number of signatures. Once the limit is reached, the private key is exhausted and   
> reuse breaks security guarantees. Previously, the PQC component had no proactive warnings when keys approached exhaustion, no enforcement before signing, no health check integration, and no usage counter persistence across restarts.
