I think this breaks the transpiled CJS version as it changes the shape of the exported object:

// src/index.js
import * as ShardImport from './shard.js'

export const shard = {
  ...ShardImport
}

// dist/cjs/index.js
var shard$1 = require('./shard.js');
const shard = shard$1;

exports.shard = shard;

vs

// src/index.js
export * as shard from './shard.js'

// dist/cjs/index.js
var shard$1 = require('./shard.js');
const shard = shard$1;

exports.PREFIX = shard.PREFIX;
exports.Prefix = shard.Prefix;
exports.README_FN = shard.README_FN;
exports.SHARDING_FN = shard.SHARDING_FN;
exports.ShardBase = shard.ShardBase;
exports.Suffix = shard.Suffix;
exports.parseShardFun = shard.parseShardFun;
exports.readShardFun = shard.readShardFun;

If I change /src/index.js to:

export const Errors = ErrorsImport
export const shard = ShardImport

I get:

export { BaseDatastore } from "./base.js";
export { MemoryDatastore } from "./memory.js";
export { KeyTransformDatastore } from "./keytransform.js";
export { ShardingDatastore } from "./sharding.js";
export { MountDatastore } from "./mount.js";
export { TieredDatastore } from "./tiered.js";
export { NamespaceDatastore } from "./namespace.js";
export const Errors: typeof ErrorsImport;
export const shard: typeof ShardImport;
export type Shard = import("./types").Shard;
export type KeyTransform = import("./types").KeyTransform;
import * as ErrorsImport from "./errors.js";
import * as ShardImport from "./shard.js";
//# sourceMappingURL=index.d.ts.map

Can you try overwriting the generated index.d.ts with the above locally and see if it fixes the problem?
