Annotations
hypothesis
Inline map_draw sprite rendering, local copies of palette flags, eliminate function calls
next_action_hint
The draw side is only 26% of time. Focus on the update workload or try larger architectural changes.
result
291ms — same as -O3 baseline (287ms). Draw time slightly improved but within noise. The map_draw optimization didn't make a measurable difference because most tiles are 0 (skipped).
rollback_reason
No significant improvement
