[evalstate]

Cluster merge run for cluster-41211-3.

Merged:

• model: Add DEIMv2 to Transformers huggingface/transformers#44339: Canonical cluster PR; fetched from upstream and merged cleanly with no conflicts.

Skipped:

• Add-Deimv2 huggingface/transformers#41291: Open overlapping DEIMv2 PR outside the cluster; older partial implementation and not selected for merge.
• Add DEIMv2 model, image processor, and basic tests huggingface/transformers#41356: Older overlapping DEIMv2 PR superseded by model: Add DEIMv2 to Transformers huggingface/transformers#44339; not suitable to keep once canonical PR is merged.

Failed:

• None.

Notes:

• The requested branch did not exist locally, so it was created from origin/main before merge work started.
• Cluster inspection via pr-search-cli showed cluster PRs Add DEIMv2 model, image processor, and basic tests huggingface/transformers#41356 and model: Add DEIMv2 to Transformers huggingface/transformers#44339 for issue Add DEIMv2 huggingface/transformers#41211.
• Keyword search also surfaced open PR Add-Deimv2 huggingface/transformers#41291 as additional overlapping DEIMv2 work.
• A local test merge of Add DEIMv2 model, image processor, and basic tests huggingface/transformers#41356 on top of merged model: Add DEIMv2 to Transformers huggingface/transformers#44339 produced add/add conflicts in docs/source/en/model_doc/deimv2.md, src/transformers/models/deimv2/init.py, src/transformers/models/deimv2/configuration_deimv2.py, src/transformers/models/deimv2/modeling_deimv2.py, and tests/models/deimv2/test_modeling_deimv2.py; the merge was aborted cleanly.
• Repo was left on the merge branch with only model: Add DEIMv2 to Transformers huggingface/transformers#44339 merged and no merge in progress.

Next steps:

• Run targeted validation for the merged DEIMv2 implementation, then run make style or make fix-repo if preparing follow-up work.
• If this branch is to be reviewed by a human, note that Add DEIMv2 model, image processor, and basic tests huggingface/transformers#41356 and Add-Deimv2 huggingface/transformers#41291 overlap heavily with the merged canonical PR model: Add DEIMv2 to Transformers huggingface/transformers#44339.
