Missing explicit type on non-exported symbol?

[greggman]

I have code something like this

// things.ts
export type ThingDef = {
    size: number;
};

const createThingDefs = <T extends Record<string, ThingDef>>(defs: T): { readonly [K in keyof T]: ThingDef } => defs;

export const kThingInfo = createThingDefs({
  bear: { size: 20 },
  chicken: { size: 1 },
} as const);

export type ThingType = keyof typeof kThingInfo;

// index.ts
import { kThingInfo, ThingType } from './things.js';

export { ThingType };

export function getThingSize(type: ThingType): number {
  return kThingInfo[type].size;
}

The only things I want to export is the type ThingType and getThingSize but jsr complains about kThingInfo even though AFAICT it's not public and shouldn't need to be

❯ npx jsr publish --dry-run

Same issue here, with a failing Github action if it helps. It’s especially curious as of the three errors, one is using satisfies and one could be simply inferred which should not cause slow types.
