Colby MchenryandClaude Opus 5.5 d03e4dbf6f fix(resolution): an unexported ES module binding is not reachable cross-file (#2162)
The sealed-module rule only covered modules exporting nothing. Per symbol
now: a JS/TS top-level binding declared by its own statement (function,
const/let/var, class, interface, type, enum) in an ES module is reachable
from another file only if it's exported — the `export` keyword (node flag or
its line), an `export { a as b }` list, `export default x` or
`export default { a, b }`. Classic scripts, CommonJS, `declare global`,
`.d.ts`, qualified members, object-literal members (zustand store actions)
and `proto.x = function x()` are exempt. Applied at the reachability gate,
so the winner is rejected rather than another promoted.

A/B (edges removed / added): zod -229 (package `z` imports → a local `z`),
excalidraw -66 (DOM `Element` → a test helper's type), kit -50, typeorm -47
(`import { ColumnMetadata } from "typeorm"` → a fixture's local), trpc -26,
hono -8, axios -1; express byte-identical.
