SDL queries the SCHED_OTHER range before it sets a thread priority. It gets the same 256 to 767 range as SCHED_FIFO and SCHED_RR, which pthread_setschedparam applies regardless of policy. The console's answer is unverified and recorded in TechnicalDebt. Co-Authored-By: Claude Opus 5.5 <noreply@anthropic.com>
