Peer dependencies

zod, unthrown and @unthrown/standard-schema are peer dependencies, not bundled ones. The package hands back real ZodObjects and real Results built from your copies. If it pinned its own, a consumer would end up with two copies of zod in the tree, and identity checks — result instanceof Result, schema instanceof z.ZodType, or composing an entity into your own z.object({...}) — can silently misbehave across the boundary between two copies of the same package.

So all four are installed together:

pnpm add @btravstack/entity zod unthrown @unthrown/standard-schema

The declared zod range is ^4.3.0, and the floor is measured rather than guessed: the full surface typechecks, emits declarations and passes its runtime assertions on 4.3.0. Nothing here needs a later minor, and monorepos commonly pin one zod across every package, so the range is kept as wide as it is true.
