Per the M15 design (docs/zh/plans/riir/M15-render-process-isolation.md): - ipc.rs moved into oakrender with protocol v2: hello_caps, render_batch, batch_accepted, frame_failed; main-process-assigned slots; BGRA8 slot format. POSIX shm verified to 1GiB on macOS. - ProcessDispatcher: spawns oak-worker processes, handshake, stdio NDJSON control, shm segment lifecycle with generation-tagged keys, crash detection with bounded restart and frame redispatch, zero-copy ShmFrameRef delivery and copy counters. - PreviewScheduler: interleaved batch claiming (frame % W per worker, no work stealing), seek > playback-distance > background priority, credit-based flow control, crash recovery. - oak-worker renders for real: graph snapshot deserialization, montage decode+composite straight into the assigned shm slot, F32->BGRA8 final conversion in-worker, OFX plugin executor installed in-worker, crash hooks for isolation testing. Thread pool coexists for now (S2 removes it). Integration tests cover two-worker zero-copy rendering, crash isolation with redelivery, and real H.264 footage decode into slots.
