Lukas Wirth 9f8a24070e open_ai: Preserve separators between reasoning summaries (#62466)
OpenAI reasoning summaries are streamed as multiple indexed parts, and
each new reasoning output item starts its indexes at zero. The Responses
event mapper previously treated those indexes as global, so adjacent
reasoning items could be concatenated without whitespace, producing text
such as `**First item****Second item**`.

Track the current summary part by both its item ID and summary index,
and emit a separator whenever that pair changes. Text delta events now
retain their summary index as a fallback when a separate part-added
event is absent, while sharing the same boundary handling to avoid
duplicate separators.

Testing performed:

- `cargo check -p open_ai`
- `cargo nextest run -p open_ai`
- `cargo fmt -p open_ai -- --check`
- `./script/clippy -p open_ai`

Release Notes:

- Fixed missing separators between OpenAI reasoning summaries.

Licensing

Zed source code is licensed primarily under GPL-3.0-or-later, with Apache-2.0 components where marked.

License information for third party dependencies must be correctly provided for CI to pass.

We use cargo-about to automatically comply with open source licenses. If CI is failing, check the following:

  • Is it showing a no license specified error for a crate you've created? If so, add publish = false under [package] in your crate's Cargo.toml.
  • Is the error failed to satisfy license requirements for a dependency? If so, first determine what license the project has and whether this system is sufficient to comply with this license's requirements. If you're unsure, ask a lawyer. Once you've verified that this system is acceptable add the license's SPDX identifier to the accepted array in script/licenses/zed-licenses.toml.
  • Is cargo-about unable to find the license for a dependency? If so, add a clarification field at the end of script/licenses/zed-licenses.toml, as specified in the cargo-about book.
