Native-allocator expandable segments to cut Qwen-Image-Edit fragmentation OOMs on the A6000 (a ~2 GB alloc failing with 1.75 GB free while 45 GB sat allocated + reserved-but-unallocated). Cache-preserving — packs better without unloading the checkpoint, so no edit-latency hit. Paired with the existing --disable-cuda-malloc (incompatible with cudaMallocAsync). Deployed + recreated on irv-ml1; verified env present, PyTorch reads it, container healthy. comfy-dev request 2026-06-25.
