WalkthroughThe client now accepts absent or null error fields in buffered and streaming responses. It continues to reject non-null errors, explicit error events, and typed error payloads. Tests cover buffered validation, stream validation, and the ChangesResponse validation
Priority: ⬇️ Low Estimated code review effort: 2 (Simple) | ~15 minutes Merge Risk: 🔵 Low · up to The response-validation behavior is correct but subtle; documenting the null-versus-explicit-error distinction will reduce the chance of a later regression before merging. 🚥 Pre-merge checks | ✅ 5✅ Passed checks (5 passed)

Document the nullable-error validation contract. The new behavior is intentionally nuanced. Record it in the private helper and its regression tests.

As per coding guidelines, Rust changes need concise comments for non-obvious private helpers and tests that encode important behavior.

Fresh integration verification at published product head Built both native server and soak from that exact commit, then ran a five-minute real-provider Stage-configured smoke through Docker Compose: concurrency 1, short-interactive, output-token budget 512, retries disabled.
This complements the same-condition baseline/fixed one-minute A/B in the description. It is not a response-completeness claim: existing acceptance of incomplete terminals and buffered minimal-shape validation are unchanged. It does not prove Stage escalation or long-duration stability. All currently reported GitHub checks pass at this PR head. No merge was performed. |

"error": null.Both buffered and SSE validation currently reject any top-level
errorfield. A nullable error field is not an error. Reject only non-null values, while preserving rejection of explicit SSEevent: errorand JSONtype: error.Only
