Malte UblandClaude Opus 5.5 c208973d75 Read T[keyof T] as unknown for T bound to an unknown-valued record ...

Inside a generic body Object.entries(t) over T extends Record<string,
unknown> types its values 'keyof T extends never ? unknown : T[keyof T]'.
An instance whose T maps to the checked-dynamic value now reads both
branches as unknown.
