# E-DEP-003

> Doctor found an installed zod older than 3.25, which breaks the build the moment Vendo's wiring pulls in the AI SDK.

```text deps/zod-floor theme={null}
broken: installed zod@<version> predates the zod/v3 + zod/v4 subpaths the AI
SDK imports (needs >=3.25) — the app build fails inside ai@6; bump within
zod 3: <bump command>
```

`<version>` is your installed `zod` version, and `<bump command>` is the
exact command doctor generated for your package manager.

`check: deps/zod-floor` · `error_code: E-DEP-003` · `doctor exits: 1`

## What you're seeing

Without the fix, `next build` (or any bundling build) fails with
`Package path ./v3 is not exported from package zod`, a module-not-found
buried inside `ai`.

## Why

`ai@6` imports the `zod/v3` and `zod/v4` subpaths, which first ship in zod
3.25. When your app pins an older zod, usually a common `^3.2x` range that
resolves below 3.25, that pin wins the installed tree, and the build breaks
the moment Vendo's wiring pulls `ai` into the bundle.

## The fix

Bump zod within v3. 3.25 satisfies the common `^3.2x` ranges and keeps zod 3
semantics.

```bash theme={null}
npm install zod@^3.25.0
```

`vendo init` detects this and offers the bump automatically; this check
catches hosts that declined or predate that detection. Hosts already on zod
4 are unaffected, since zod 4 exposes both subpaths. Re-run
`npx vendo doctor` once the install finishes.
