GoogleProvider attaches raw tool_call dicts as ``provider_blocks`` on the finish chunk for ``thought_signature`` round-trip (``_google.py:_iter_stream``). When the same turn streamed Gemini's ``reasoning_content`` as ``reasoning_delta`` chunks, the prior synthesizer bailed out the moment ``provider_blocks`` was non-empty — so the captured reasoning was visible live but lost on page reload. Replace the early-return-if-non-empty check with a reasoning-bearing type test (``thinking`` / ``redacted_thinking`` / ``reasoning`` / ``reasoning_text``). When none of those types appear, append the synthetic ``reasoning_text`` block to the existing list rather than replacing it — preserving Google's tool-call fidelity blocks. Also addresses two doc-accuracy review findings: - ``LLMProvider.extract_reasoning_text`` docstring no longer claims OpenAI Chat / Responses are unwired (Phase 3+4 shipped extractors). - Add the method to the Protocol methods table in ``docs/architecture.md`` (was missing alongside the class diagram).
