ChuckandClaude Opus 5.5 1afb2383cd feat(vegas): prefetch_gate on by default, after an A/B/C soak on hdpi
Two runs per arm, about 81,000 frames each, order A B C C B A:

  A  step 1 as is            0.90% late, 20.1 per 10k two+ refreshes late
  B  switch_interval_ms 1    0.78% late, 15.8 per 10k
  C  prefetch_gate           0.60% late,  2.5 per 10k

No freezes in any arm, and the next group was ready at every strip
extension, so parking the prefetch thread (3-6s per 8-minute run) cost
nothing visible. The gate is now on unless vegas_scroll.prefetch_gate is
false; on a stock binding it cannot work and says so at INFO once a run
rather than warning on every install. switch_interval_ms stays off.
