Normalize incoming reasoning at the shared heading boundary and completed extraction, and flatten auxiliary content and reasoning before accumulation. Reuse the existing text flattener with no implicit fragment separators. Combine the earliest related work from zsuroy (#85791), the diagnosis and patch from 2025hcsmile2010-hue (#104711, #104848), and completed extraction work from liuhao1024 (#104717) as a slim redo, not a verbatim cherry-pick. Two invariant tests exercise the real SDK and local HTTP fixture across main streaming, Relay collection, auxiliary sync/async and completed output. The standalone matrix improves from 32/84 to 84/84, preserving answers.

"""Boundary repair for providers that stream reasoning as discrete summary parts.
|
|
|
|
Reasoning-summary models (OpenAI gpt-5.x and Responses-API relays onto the chat wire) emit one
|
|
``reasoning_content`` delta per *completed* summary part, each opening with a bold heading.
|
|
The chat wire lacks the Responses API's ``summary_index`` delimiter (verified live on Nous
|
|
Portal ``openai/gpt-5.6-sol``), so plain concatenation glues ``**One****Two**`` into one
|
|
half-bold paragraph. The boundary is re-derived from a delta opening a bold heading, matching
|
|
the blank-line join Hermes' own Responses adapter does.
