Refreshed against current main (c1973427bddb). The new head (be63d43c0b72) is conflict-free and changes only the API reference and generation metadata. All client source, public APIs, exception types, runtime behavior, dependencies, workflows and compatibility tests are byte-identical to main, including the recently published access-program builder defaults. The reference retains exactly the 643 reviewed error-response changes and no other semantic changes. Fresh CI is running.

[markstuart-oai]

Thanks @dpiet-oai and @saioai for reviewing. All repository checks are now successful or intentionally skipped, and the downstream compatibility run also passed all 236/236 SDK tests: https://github.com/openai/ok-test/actions/runs/36213094128. The reviewed head remains be63d43c0b72; only the API reference and generation metadata differ from main, with client source and error handling unchanged.
