Summary

The type tests run on @definitelytyped/dtslint 0.0.176, whose dependencies keep request, tar 6, form-data 2, qs 6.5.5, tough-cookie 2 and uuid 3 in the lockfile. Two commits: TypeScript ^5.2.2 to ^5.9.3, then TSTyche 7.2.5 in place of dtslint. The test:dts script names, the turbo task and the CI step stay.

 // packages/react/package.json
-"test:dts": "dtslint --localTs ... __dtslint__ && dtslint --localTs ... __dtslint-react17__",
+"test:dts": "tstyche",

 // packages/core/__dtslint__/core.ts
-// $ExpectType string
-const combined1 = cx(class1, 'active');
+expect(cx(class1, 'active')).type.toBe<string>();

• The 11 $ExpectType comments become expect(...).type.toBe<...>() with the same types; a tstyche.json per package selects the existing folders.
• The 12 @ts-expect-error lines stay; checkSuppressedErrors: false in packages/react/tstyche.json stops TSTyche reading the text after the directive as an expected message (dtslint did not either).
• The React 17 test asserts expect(Button).type.toBeCallableWith({}) instead of calling Button({}); the stub is unchanged.
• tslint.json and three placeholder index.d.ts files go. dtslint 0.2.x was not an option: 0.2.47 only works inside a DefinitelyTyped checkout layout.
• TypeScript stops at 5.x: 6.0 deprecates the baseUrl and moduleResolution: node options of the root tsconfig. Built declarations differ in @linaria/atomic and @linaria/postcss-linaria, which get a patch changeset; the others are identical.

Evidence

• A lockfile audit against the npm advisory database goes from "27 vulnerable packages in 34 instances" on master to "23 vulnerable packages in 28 instances"; those six entries are gone and none is new.
• pnpm turbo run test:dts exits 0: 3 assertions in @linaria/core, 9 in @linaria/react.
• Five deliberate breaks each make it exit 1 and name the file, and reverting restores exit 0: a wrong expected type in the core test and in styled.ts, an unused @ts-expect-error in styled.ts and in styled-jsx.tsx, and Button('ok') in the React 17 test. That test also fails when a scratch copy of packages/react/src/styled.ts requires children.
• TypeScript 5.9.3 (2025-09-30) and TSTyche 7.2.5 (2026-09-10) are the only new versions.

With pnpm 9.15.9 and Node 24.4.1 these exit 0 (the install, typecheck and sp:check also on the first commit; pnpm lint needs a built checkout):

pnpm install --frozen-lockfile --ignore-scripts --strict-peer-dependencies
TURBO_FORCE=true pnpm turbo run typecheck
pnpm turbo run test:dts
pnpm lint
pnpm sp:check

Left out

• TypeScript 6 and 7.
• The other dev tools.
• Renaming the __dtslint__ folders and the CI step name.

Not verified

• A CI run of this pull request.
• Node 22 (the repository floor is 22.12.0; the local runs used 24.4.1).
• test:dts on the first commit alone.
• A merge with other changes to pnpm-lock.yaml, which would need the lockfile regenerated.
