The round-4 fused crop loops re-derived each frame's detection image with
one single-row converter call per frame - N host sync points where the
round-3 crop did one batch. The grouped form converts the chunk's gathered
rows in one elementwise pass (bitwise the per-row rows) and is bounded by
the caller's chunk; the paste-fallback row form stays. Pins guard the
conversion count. The paste stage itself is proven byte-equivalent to
32e6628 (dispatch, cores, tails); timed CPU stubs show no superlinear
term in either tree - the real-box burn needs the owner's log to attribute
(the device-mode verdict under real VRAM pressure is the only paste-stage
quantity this diff can move).
- R1: the face helper is constructed on the pack device (was the offload
device); load_device() explicitly places the detector and the parser with
a logged CPU fallback, offload() mirrors the restore, the YOLO .device
skew is closed (P-D1..P-D5).
- R2: detection streams per max_clip_length group (no full-clip convert-in
retention), crop is fused into a chunk-bounded restore loop with
preallocated staging, the paste tail keeps one contractual float32
buffer, the helper is released after every run; golden fixtures pin the
outputs bitwise (P-M1..P-M7).
- The diagnosis: the OOM was O(frames) whole-clip host buffers, not the
faces (the detector/landmark path was already GPU-placed);
max_clip_length never bounded convert-in or the paste tail.
- Gate: 523 passed, 6 skipped, 7 deselected, 0 failed (baseline 505).
process_image_sequence converts the batch once, detects per frame while capturing the frames the detector saw (the read_image products, including the min(h,w)<512 upscale), estimates each affine once with the vendored call, crops with cv2.warpAffine (decision D2: the uint8-bound warp stays bit-exact; the batched grid_sample helper stays parked and pinned), normalizes the whole crop batch on the device, keeps the KEEP chunk contract byte-identical, converts the restored faces with one batched tensor2img, pastes through the batched paste with the vendored fallback, and stacks the output in one transfer. The paste canvas is the detection frame, so small frames keep the base's upscaled canvas (the round-1 QA defect F1, fixed and pinned). A failed affine degrades to the neutral crop with a warning instead of crashing like the base. Progress still reports num_frames * 4 in the four families. Pins: the read-once/affine-once/chunk-contract AST guards, the progress contract, and the new end-to-end base-vs-shipped suite (tests/test_gpu_sequence_e2e.py) with the real vendored helper - measured drift 0/255 on the vendored branch, 1/255 on the batched branch.
The pack owned a private stdlib handler, so every line bypassed the coloured console of ComfyUI, and the call sites carried a literal KEEP prefix. The logger now adopts the host console (no handler and propagate=True when ComfyUI is present, one private handler when it is not), the tag lives in a single filter, and the console writes of the pack (the tqdm bars of the processor, the prints of the vendored facelib) reach it through a thread-scoped redirect.
