- Audio tickets join the process backend: render_audio_batch wire
message, workers mix straight into shm slots (SLOT_FORMAT_AUDIO_F32),
ShmAudio payload with release semantics, crash isolation covers audio
renders; playback audio uses an async 4-chunk prefetch drained on the
UI tick (also fixes the sub-60fps chunk truncation bug); oversized
ranges and dispatcher outages fall back to in-process inline.
- Per-ticket slot formats: force_format is honored (exports request
F32 slots, dropping the BGRA8 round-trip and its 8-bit quantization);
segments grow on demand via worker-idle rebuild with generation
handoff; the scheduler filters over-capacity tickets.
- Adaptive defaults: 128-256MB/worker segment budgets drive slots per
worker, batch size follows workers/slots; bench_process example
measures throughput and adjacent-frame completion deltas
(e.g. 4 workers: 841 fps, 4.6ms mean delta).
