| - `torch.nn.MultiheadAttention` is the common instance: it passes `self.out_proj.weight` straight to `torch.nn.functional.multi_head_attention_forward` instead of calling `self.out_proj`, so the hook on `out_proj` never fires. `SiglipVisionModel`'s attention pooling head wraps one — see `tests/pipelines/hunyuan_video/test_hunyuan_video_framepack.py`, whose `image_encoder` is excluded for this reason. | ||
| - `HunyuanDiTAttentionPool` (`src/diffusers/models/embeddings.py`) shows the same failure without an MHA module: a plain `nn.Module` that hands its `q_proj` / `k_proj` / `v_proj` / `c_proj` weights to `torch.nn.functional.multi_head_attention_forward`, so all four projections stay offloaded rather than just one. `HunyuanDiT2DModel` opts out of group offloading entirely with `_supports_group_offloading = False`. | ||
| - Before adding a skip or an exclusion, confirm the failure still reproduces — several existing skips are stale, having outlived the upstream cause. | ||
| - **A migration that surfaces a `src/` gap marks the test `xfail`, it does not patch the pipeline.** Give the marker a module-level name and a `reason` naming the exact gap (`PNDM_*` in `tests/pipelines/pndm/test_pndm.py` is the worked example), and prefer `strict=True` so the marker reports XPASS — and gets deleted — the day the pipeline is fixed. Use `strict=False` only when one mark covers a group whose members do not all fail. Marking a whole test class keeps the mixin's own marks (`@is_memory`, `@require_accelerator`) intact; overriding individual inherited tests drops the decorators they were declared with, so re-declare those too. |

I think it's better to xfail things where we need core changes while doing test PRs. xfail is better than skipping the tests.

Just import level changes in the animdatediff series because we moved the from_pipe tests in a dedicated mixin.
