Description

Description

Copilot Chat can deliver its opaque reasoning value after assistant text has started. The parser retains that value in response-level finish metadata, but the completed text part does not receive it, so part-based Session replay can lose the provider state.

Expected behavior

The terminal text-end event carries the final captured opaque reasoning metadata for either packet ordering.

Scope

This concerns the Copilot Chat parser only. PR #45694 contains the focused fix and regression coverage.

Research direction

Start by reviewing PR #45694 and the Copilot Chat parser behavior described here, focusing on the terminal text-end event and both packet orderings. Done means the completed text part carries the final opaque reasoning metadata in either order, with regression coverage confirming the behavior.
