Zod 4 made the key schema mandatory for z.record, so the single-argument
z.record(valueType) form is a compile-time error (TS2554) when built against
Zod 4. @copilotkit/react-core declares zod ">=3.0.0", so downstream apps on
Zod 4 are affected; runtime parsing is unaffected under both majors.
- react-core + vue MCPAppsActivityContentSchema: toolInput now uses the
two-argument z.record(z.string(), z.unknown()) form
- react-core defineToolCallRenderer test: same fix for a metadata schema
- add a toolInput field-contract test (round-trips mixed value types)
- add copilotkit/no-single-arg-zod-record oxlint rule (autofix), enabled as
error for packages/**; the incompatibility is type-level, so no runtime
test can guard it while the workspace lockfile pins Zod 3
