* Fall back to file-path IDs for non-exported package files
Instead of synthesizing a 'name/dist/<path>@version' specifier (which
hardcoded the dist/ output convention), non-exported workspace/node_modules
files now return moduleSpecifier: undefined and let the SWC plugin's
'./{filepath}' fallback produce per-file IDs. This is the same path local
app files have always taken and avoids the dist/ assumption flagged in
review. The build-time duplicate-ID check stays as the safety net.
* Dedupe virtual-entry imports by canonical module identity
When both the source and the compiled-dist copies of the same workspace
package export end up in discoveredSteps/discoveredWorkflows (e.g. the
'workflow' package's internal/builtins in monorepo dev), they resolve to
the same module via esbuild's package resolution. The virtual entry was
emitting BOTH 'import "workflow/internal/builtins";' (the built-in
preamble) and 'import "../../packages/workflow/src/internal/builtins.ts";'
(via the isWorkspaceSourceBackedPackageFile carve-out in createImport),
which made the swc plugin transform both copies and generate duplicate
step IDs.
Track a per-bundle set of emitted module identities (package specifier
when reachable, otherwise the file path) and skip files whose identity
has already been imported. The steps bundle pre-seeds the set with the
built-in steps specifier so workspace step files at that path don't
emit a competing relative-path import.
* Stop rewriting workspace package /dist/ -> /src/ during Next.js discovery
The Next.js deferred builder's `resolveSourceBackedPackagePath` rewrote
any discovered `/dist/` path to its `/src/` sibling for workspace
packages and for `workflow`/`@workflow/*` tarballs. That made the
discovered step file list point at source files while base-builder's
esbuild bundle (which builds the workflow VM and step registrations)
resolved the same package imports through `pkg.exports` to
`/dist/`. The workflow proxy ID — generated from the dist path —
didn't match the step bundle's registration ID — generated from the
src path — producing "Step function not registered" failures at
runtime, most visibly with @workflow/ai's doStreamStep on Vercel and
Windows Next.js deployments.
App code that imports a package by name should resolve naturally
through pkg.exports; the loader has no business reaching into the
package's source tree. Drop the rewrite (and the now-unused
`resolveCopiedStepImportTargetPath` helper that supported it).
Workspace packages are still discovered — that's a separate predicate
(`shouldPreferSourceBackedPackagePath`) which only gates inclusion,
not path translation.
Verified locally with the nextjs-turbopack workbench: agent e2e suite
(19 tests, including the failing `agentBasicE2e`) and the
addTenWorkflow duplicate-name suite all pass.

* fix(next): always apply turbopack content condition regardless of builder mode
When lazy discovery is enabled (deferred builder), shouldApplyTurboCondition
was false, so turbopack.rules were added with no content filter — causing the
workflow loader to run on every JS/TS file. Apply the content condition
unconditionally so the loader only fires on files with workflow directives.

* [next] make lazyDiscovery the default in withWorkflow
Flips the default for `workflows.lazyDiscovery` from `false` to `true`
so new projects get deferred workflow discovery automatically on Next.js
versions that support deferred entries (>= 16.2.0-canary.48). Older
versions continue to fall back to eager discovery.
Users can still opt back into eager discovery explicitly by passing
`workflows: { lazyDiscovery: false }`.
Also:
- Remove the now-redundant `lazyDiscovery: true` from the Next.js
workbench apps.
- Reword the fallback warning for clarity when lazy is the default.
- Update the local-build e2e assertion to match the new warning text.
- Update the withWorkflow docs with the new default.
* [workbench] remove commented 'export default nextConfig' lines
* docs: split v4/v5 content, fix version switcher end-to-end
## Content restructuring
- Split `docs/content/docs/` into `docs/content/docs/v4/` and
`docs/content/docs/v5/` so each version is a fully independent
content tree with no shared-file coupling
- v4 excludes the four pages that are v5-only (AbortController
cancellation docs and the serializable-abort-controller internal page)
- v5 retains all pages; `preRelease` frontmatter field removed (no
longer needed now that each version is its own folder)
- Removed `AbortController` / `AbortSignal` from v4 serialization page
(section moved to v5 only)
## Fumadocs source
- Added `v4docs` and `v5docs` as separate `defineDocs()` collections in
`source.config.ts`; shared `docsSchema` (no more `preRelease` field)
- `source.ts` exports both `source` (v4, `baseUrl: /docs`) and
`v5Source` (v5, same base URL)
## Version routing
- `version-source.ts` simplified: `filterPreReleaseFromNodes` and
`isPreReleaseUrl` logic removed; v4 tree uses `source`, v5 tree uses
`v5Source` + `rewriteNodeUrls`
- v4 `page.tsx`: removed `preRelease` guard (v4Source has no such pages)
- v5 `page.tsx`: uses `v5Source` for `getPage` / `generateStaticParams`
/ `generateMetadata`; `v5Link` wrapper rewrites `/docs/…` hrefs to
`/v5/docs/…` so inline MDX links stay in the v5 context
## Versioned cookbook
- Added `app/[lang]/v5/cookbook/` layout + page (mirrors v4 but uses
`v5Source`, `rewriteCookbookUrlForVersion`, and `V5CookbookLink`)
- `getCookbookTree` accepts a `versionPrefix` parameter; sidebar URLs
are prefixed accordingly (`/v5/cookbook/…`)
- `cookbook-tree.ts`: added `skipVersions?: string[]` per-recipe field
for version-specific exclusions; `distributed-abort-controller` is
marked `skipVersions: ['v5']`
## Version switcher — state & navigation
- New `VersionProvider` context (`hooks/geistdocs/use-version.tsx`)
backed by `localStorage`: URL is source of truth on versioned pages,
`localStorage` carries the preference across non-versioned pages
(cookbook overview, worlds, etc.)
- `VersionSwitcher` uses `useVersion()` context instead of URL-only
detection; now visible on all pages including cookbook
- `DesktopMenu` and `MobileMenu` use `activeVersion` from context so
the "Docs" and "Cookbook" navbar links resolve to the correct version
prefix on every page
- `buildVersionUrl` expanded to handle `/cookbook/…` paths alongside
`/docs/…`; non-versioned routes (worlds, api) return unchanged
- `switchVersion` does a `HEAD` probe before navigating; falls back to
the versioned cookbook or docs home if the target page doesn't exist
in that version (handles v4-only → v5 and v5-only → v4 cases)
## Cookbook content (v5)
- Rewrote `agent-cancellation` recipe using a single `AbortController`
pattern; removed Hard Cancellation vs Stop Signal two-approach
comparison
- Deleted `distributed-abort-controller` recipe from v5 (native
`AbortController` serialization makes it unnecessary)
- Removed references to distributed-abort-controller from
`cookbook/index.mdx` and `common-patterns/timeouts.mdx`

* Warn when serverExternalPackages hides workflow-enabled packages
Add a build-time warning when packages in serverExternalPackages contain
workflow code ('use step', 'use workflow', or serialization classes).
These packages are completely invisible to the workflow compiler when
externalized, causing silent runtime failures.
The warning detects workflow patterns via two methods:
- Fast path: check package.json dependencies for @workflow/serde
- Thorough path: read the package entry file and run pattern detection
Also adds documentation in the serialization guide about the
externalization footgun for 3rd-party packages.
* Auto-remove workflow packages from serverExternalPackages
When workflow-enabled dependencies are externalized in Next.js, compiler transforms are skipped and runtime failures follow. Detect those packages in withWorkflow, remove them from serverExternalPackages for the current build, and keep a generalized externalPackages warning fallback for non-Next builders.
* Address review feedback: add entry-point limitation comment and missing test case
