Local mode currently accepts negative integer point IDs and values above
2**64 - 1, outside the documented unsigned 64-bit range. For example, upserting
id=2**64 succeeds, but a subsequent scroll with a slice filter raises
OverflowError while encoding the ID.

Validate the integer range during point validation, before any points in the
upsert are written. This also prevents a bad ID late in a request from leaving
earlier inserts or updates applied. UUID handling is unchanged.

Tests cover both upsert formats, in-memory and persistent clients, unchanged
records after rejection and reopening, and valid boundary IDs through
2**64 - 1. The eight rejection cases fail before the fix; all 20 new cases
pass afterward.

Validation:

python -m pytest qdrant_client/local/tests tests/test_in_memory.py tests/test_local_persistence.py -q --tb=short
# 170 passed

Ruff 0.4.3 formatting passes. Tested with Python 3.14 and Pydantic 2.13.5;
the server-backed congruence suite was not run.

📝 Walkthrough

Walkthrough

The local collection now rejects integer point IDs outside the unsigned 64-bit range during pre-write validation. Tests cover rejected batches for in-memory and persistent stores, unchanged existing data, valid boundary integers, UUID strings, and UUID objects. Persistence reopening and UUID string normalization are also tested.

Merge is safe with bounded follow-up: make the test fail on mismatched fixture lengths so it continues to protect invalid-ID batch rejection.

Make test input cardinality explicit.

If any fixture list becomes shorter, zip can omit the invalid ID and test a smaller batch. The project supports Python 3.10 and later, so strict=True is compatible.

Proposed fix
-                for id_, vector, payload in zip(ids, vectors, payloads)
+                for id_, vector, payload in zip(ids, vectors, payloads, strict=True)
📝 Committable suggestion

‼️ IMPORTANT
Carefully review the code before committing. Ensure that it accurately replaces the highlighted code, contains no missing lines, and has no issues with indentation. Thoroughly test & benchmark the code to ensure it meets the requirements.
