Summary

partially addresses deepset-ai/haystack#11084 (partial — Qdrant).

After the in-place mutation warning was added to Document in deepset-ai/haystack#10650, four tests in QdrantSparseEmbeddingRetrieverIntegration trigger DeprecationWarning by mutating Document.sparse_embedding and Document.meta directly after construction.

Affected tests and mutations:

Fix: replace all for-loop field assignments with dataclasses.replace() list comprehensions:

# Before
for doc in filterable_docs:
    doc.sparse_embedding = generate_sparse_embedding()

# After
filterable_docs = [
    dataclasses.replace(doc, sparse_embedding=generate_sparse_embedding()) for doc in filterable_docs
]

Test plan

• Run pytest -m "integration" integrations/qdrant/tests/test_sparse_embedding_retriever.py — should pass with zero DeprecationWarning about in-place mutations
