validate_dense_vector and validate_multivector checked isnan, so NaN was rejected at write time while +-inf slipped through, despite both docstrings claiming parity with the server. Once stored, an infinity corrupts silently: * COSINE normalises it into NaN, and the corrupted point then sorts to the top with a NaN score, ahead of an exact match; * DOT and EUCLID score it inf; * an inf among a sparse vector's values scores inf. Check isfinite over the float32 values that actually get stored, so a value that is finite as a Python float but not as float32 (1e40) is caught as well, and keep numpy's overflow warning out of the user's output. Query-time checks in distances.py and multi_distances.py still reject only NaN; they are left alone here to keep the change reviewable.

📝 WalkthroughWalkthroughLocal dense, multivector, and sparse vector validation now rejects NaN, infinity, and values that overflow during float32 conversion. Dense and multivector validation share a finite-value helper and error constant. New tests cover direct validation, rejected upserts, retained vectors after rejected rewrites, and write atomicity expectations. Priority: ➖ Normal Estimated code review effort: 3 (Moderate) | ~20 minutes Change: Bug fix · Severity of issue fixed: Medium Suggested reviewers: Merge Risk: 🟡 Moderate · up to Sparse queries that previously accepted infinity-valued inputs will now fail before scoring, despite the intended query-time behavior remaining NaN-only. Separate write validation from query validation before merging. 🚥 Pre-merge checks | ✅ 4 | ❌ 1❌ Failed checks (1 warning)

Keep sparse query validation NaN-only.
LocalCollection.search passes direct SparseVector queries to validate_sparse_vector. The new float32 isfinite check rejects +/-inf and values that overflow float32, although the previous check rejected only NaN. Write paths also use this validator and require finite values.
Use separate query and write validation, or add an explicit write-validation mode. Add a sparse query regression test.
