Former maintainers keep contributor standing and are welcome to open issues and pull requests like
anyone else. Authorship credit in git history, release notes, and code comments is not rewritten
when a maintainer steps down.

### Change log

- 2026-08-19 — [@Wibias](https://github.com/Wibias) stepped down as a maintainer
and is now a contributor. This follows his own decision to stop developing
opencodex; it is not a disciplinary action, and it was made with the owner's
agreement (requirement 1). Requirement 2 does not apply to a maintainer's own
resignation, which needs no second maintainer to ratify it. Requirement 3 is
met by this file and `.github/CODEOWNERS`, where the default-reviewer line
and the four runtime paths that listed him (`/src/adapters/`,
`/src/providers/`, `/src/codex/`, `/src/server/`) drop back to the two
remaining maintainers. Repository permission was reduced to read access at
the same time, so the roster and the GitHub settings agree again.

Nothing he authored is being unwound. His commits, the pull requests he
merged, the release-note attributions, and the code comments citing his
reviews stay exactly as they are, and the trust-lane gate derived from his
work in `.github/scripts/pr-sponsored-surface.cjs` keeps its attribution.
Returning to the maintainer table later would go through the same three
requirements that govern every addition.

- 2026-07-27 — [@Wibias](https://github.com/Wibias) added as a maintainer.
Requirement 1 (agreement from the project owner) is met: the owner requested
the addition. **Requirement 2 (review by another current maintainer) was
never satisfied in the form this document describes.** The three commits that
carried the addition (`a2693c02`, `dc3a4ade`, `02bbd47a`) landed on `dev` as
direct owner pushes with no associated pull request, so no second maintainer
reviewed them. Requirement 3 is met by this file and `.github/CODEOWNERS`.
The addition is in effect regardless: @Wibias holds write access on the
repository and has been merging pull requests since 2026-07-26. This entry
records the gap rather than papering over it — a later maintainer change
should go through a reviewed pull request.

P2 Badge Activate the sidecar for forced web_search_preview choices

For a routed Responses request whose tool declaration and choice both use the supported web_search_preview type, this new branch sets toolChoice to { name: "web_search" }, but extractHostedWebSearch() recognizes only type === "web_search". Consequently _webSearch remains unset, planWebSearch() returns no plan, the synthetic tool is never injected, and adapter filtering removes every unrelated declared tool, so the model produces an ordinary answer without performing the forced search. Normalize or extract web_search_preview as a hosted search too, and add a routed-planning regression case for this branch.

Add coverage for web_search_preview.

The parser now handles both web_search and web_search_preview, but this test covers only web_search. Add a second case that expects { name: "web_search" } for tool_choice: { type: "web_search_preview" }.

As per path instructions, behavior changes in src/ should have focused regression coverage in tests/.

In `@tests/responses-parser.test.ts` around lines 164 - 176, Add a focused test
alongside the existing forced hosted web_search test in the responses parser
suite, using tool_choice type "web_search_preview" and asserting
parsed.options.toolChoice equals { name: "web_search" }. Keep the same request
setup and preserve the existing web_search coverage.
