`OllamaEmbeddings.compute_source_embeddings(np.array(["hello", "world"]))` raises a validation error before sending a request. The embedding interface accepts NumPy arrays, but the adapter passes the array directly to Ollama's string-or-sequence request field. Convert NumPy text arrays to lists before the batched request. This preserves input order, the single request, model options and `keep_alive`. The tests cover Unicode/object/sliced arrays, empty input, existing list/Arrow/query inputs and API error propagation. The added input-contract tests also cover two-dimensional arrays and byte strings, with equivalent list inputs as controls. The real Ollama SDK rejects 2-D inputs and invalid UTF-8 locally, before transport. Valid UTF-8 bytes are decoded normally. No extra adapter validation is needed for these cases. Validation on Python 3.12.14 / macOS arm64: - Built the Rust/PyO3 bindings using the repository's uv/maturin environment. - The initial regression run had 5 failures and 4 passing controls on the base; all 9 passed with the fix. With the 6 additional input-contract cases, the related embedding and trust suites now total 55 passed / 11 skipped. - All Python Ruff lint and formatting checks pass. Root checks still report the same 49 lint errors and 11 documentation formatting files reproduced on the untouched base. - Separate review exercised 13 public API cases. Another 7 groups passed through a real loopback HTTP transport, including local validation, UTF-8 serialization and empty-batch model-error propagation. The regression tests use the real Ollama 0.6.2 SDK with HTTPX MockTransport. The loopback check uses an HTTP surrogate, not an Ollama daemon. No live model inference was run. A live Ollama server was unavailable locally. [The current server handler](https://github.com/ollama/ollama/blob/2cd63f7a15039ccd790e97b31edc091fa1707c56/server/routes.go#L1212) explicitly returns HTTP 200 with empty embeddings for empty input after model lookup and runner setup. The adapter preserves the existing empty-list request and its model/setup errors. This is a source check, not a live-server test. Developed with OpenAI Codex, with separate agent review and executed local checks.
