Basic (1 producer × 1 consumer): p50=75µs p95=146µs p99=152µs (target was <5ms — мы 33× ниже) 500 frames, 0 torn, 0 skipped, zero-copy verified Multi-consumer (1 × 3): p99 для всех 3: 151-152µs (identical = proof zero-copy без contention) 300 frames each, 0 torn, 0 skipped Acceptance criteria — GREEN. Переходим к Phase 1 (libcuframes API). Sync через cudaStreamSynchronize достаточен для v0.1; CUDA IPC event handles overlap отложен до v0.2. Raw measurement logs сохранены в docs/measurements/phase0-consumer-*.log для verification (4 файла из 2 scenarios). Также fixed unused variable warning в pingpong_consumer.cu.
