Nathan Rajlich 8d0928b2a2 fix(core,errors): classify SDK encryption failures as RUNTIME_ERROR (#2145)
* fix(core,errors): classify SDK encryption failures as RUNTIME_ERROR

SDK-level AES-GCM encrypt/decrypt failures are never the user's fault,
but the run-failure classifier was tagging them as USER_ERROR because
the native Web Crypto OperationError (most commonly raised by
AESCipherJob.onDone on GCM auth-tag mismatch) does not match any
RUNTIME_ERROR_CHECKS entry.

Introduce a new RuntimeDecryptionError (subclass of WorkflowRuntimeError)
that the encryption module throws when subtle.encrypt/subtle.decrypt
fails, with the original DOMException as cause plus diagnostic context
(operation, byteLength, printable/hex format prefix of the input
header). classifyRunError now picks it up via RUNTIME_ERROR_CHECKS, so
these failures surface as RUNTIME_ERROR with a proper named class for
dashboards and triage.

* Trim changeset description to one sentence

* Trim historical-context comments

* docs: add runtime-decryption-failed troubleshooting page (v4 + v5)

* fix(core): round-trip RuntimeDecryptionError context, fix formatPrefix, propagate through serialization wrappers

Addresses review feedback on #2145:

- Add a RuntimeDecryptionError reducer/reviver (+ SerializableSpecial
  entry + globalThis registration) so its `context` (operation,
  byteLength, formatPrefix) survives the dehydrate/hydrate run-error
  round trip instead of being dropped by the generic Error reducer.

- Stop capturing `formatPrefix` in the low-level encryption layer, which
  only sees the stripped AES payload (nonce bytes), not the outer `encr`
  marker. The serialization layer now attaches the real envelope prefix.

- Rethrow RuntimeDecryptionError unchanged from the serialize/dehydrate
  catch blocks instead of reframing it as a SerializationError, so an
  encryption failure during dehydration stays a RUNTIME_ERROR rather than
  being misclassified as USER_ERROR.

* fix(core): enrich stream decrypt errors with envelope prefix + fix lint

- Mirror the catch/enrich/rethrow block from serialization/encryption.ts
  around the stream-path aesGcmDecrypt() call so auth-tag failures on
  encrypted stream frames also carry context.formatPrefix = 'encr'
  (addresses review feedback). Add a tampered-frame test.
- Fix all auto-fixable Biome lint findings in the touched files
  (template literals, useless try/catch wrappers, optional chaining,
  non-null assertions).

Karthik Kalyan ff167d005d [Docs] Fix cookbook pattern for AI SDK (#2099)
* Fix cookbook pattern for AI SDK

The AI SDK cookbook entry presented `streamText` inside a `"use step"`
turn function with tools also marked `"use step"`. That implies tools
are individually durable, but the `"use step"` directive is a no-op
when called from another step — so tools run as plain inline functions
inside `runTurn`, and the durability boundary is the entire turn.

Changes:

- Remove the `"use step"` directive from tool implementations in the
  workflow code sample and add an explanatory comment.
- Update the frontmatter summary and intro paragraph to drop the
  inaccurate "tools remain durable steps" claim.
- Add a "Tools are not individually durable" entry to Pitfalls with
  consequences and mitigations (idempotency or `DurableAgent`).
- Add a `runTurn` durability-boundary bullet to "How it works".
- Add a "Tool call durability" row to the `streamText` vs `DurableAgent`
  comparison table.
- Fix two misleading Key APIs bullets that claimed tools wrap
  `"use step"` functions and that `"use step"` makes tool executions
  durable.

Applied identically to both v4 and v5 cookbook entries.

Nathan Rajlich 070bd0cea9 [next] make lazyDiscovery the default in withWorkflow (#1805)
* [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.

Karthik Kalyan ea16d04599 docs: split v4/v5 content trees and fix version switcher end-to-end (#1948)
* 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`

Pranay Prakash aee56993c7 feat: serializable AbortController/AbortSignal (#1301)
* feat: add docs and test stubs for serializable AbortController/AbortSignal

Adds documentation and test infrastructure for making AbortController and
AbortSignal serializable across workflow and step boundaries. The feature
uses a dual hook+stream backing: hooks for deterministic replay in the
workflow context, streams for real-time propagation to running steps.

Docs:
- Cancellation guide (foundations) covering AbortSignal and run cancellation
- How Cancellation Works (how-it-works) explaining hook+stream internals
- AbortSignal.timeout() error page for the workflow VM restriction
- Updated serialization docs with AbortController/AbortSignal section

Tests (all .todo stubs for TDD):
- VM behavior: AbortController API, static methods, hook integration
- Step-side: stream reader setup, abort propagation, ops queue
- Serialization round-trips: all boundaries, encryption, nested structures
- Consistency: race conditions, partial failure, eventual convergence
- E2E workflows: timeout, parallel, step-initiated, hook-triggered, replay

* fix: use correct frontmatter type for error page

Change type from "error" to "troubleshooting" to match the valid
frontmatter schema used by all other error pages.

Co-Authored-By: Claude Opus 4.6 (1M context) <noreply@anthropic.com>

* docs: address review feedback on cancellation docs

- abort() in workflow does not synchronously update signal.aborted;
  instead it queues hook resumption and the replay handles state update
- stream name and hook token are generated at serialization time (not
  deterministically in the workflow) and stored in the event log
- use throwIfAborted() instead of manual signal.aborted checks

Co-Authored-By: Claude Opus 4.6 (1M context) <noreply@anthropic.com>

* docs: document runtime change for processing abort queue items on completion

The current runtime only processes invocation queue items on suspension.
When abort() is called after the last suspension point and the workflow
completes, the queue items are dropped with a warning. Document that the
runtime needs to flush abort-related items on completion/failure too.

Add test stubs for this behavior.

Co-Authored-By: Claude Opus 4.6 (1M context) <noreply@anthropic.com>

* docs: generalize queue processing on completion to all item types

Processing pending invocations queue items on workflow completion/failure
should apply to all queue item types (steps, hooks, waits, abort signals),
not just abort-related ones. Update docs and tests accordingly.

Co-Authored-By: Claude Opus 4.6 (1M context) <noreply@anthropic.com>

* docs: abort errors in steps are automatically wrapped in FatalError

When a step throws due to an abort (AbortError from fetch, throwIfAborted,
etc.), the error is wrapped in FatalError so the step skips retries. An
abort is intentional cancellation, not a transient failure.

* feat: implement serializable AbortController/AbortSignal

Core serialization layer:
- Add AbortController/AbortSignal to SerializableSpecial interface
- Add reducers for all 4 contexts (external, workflow, step, common)
- Add revivers for all 4 contexts with stream-backed propagation
- Add reviveAbortController helper for step/external contexts
- Guard instanceof checks for VMs without AbortController global

Workflow VM:
- New workflow/abort-controller.ts with createCreateAbortController factory
- WorkflowAbortSignal class with hook-backed state
- AbortSignal static methods (abort, any, timeout blocked)
- Hook integration via invocations queue and events consumer

Supporting changes:
- Add ABORT_STREAM_NAME, ABORT_HOOK_TOKEN symbols
- Add getAbortStreamId() for system stream namespace
- Add isSystem, abortRequested, abortReason to HookInvocationQueueItem
- Add isSystem to world Hook entity and events
- Wrap AbortError in FatalError in step handler (skip retries)
- Add AbortController/AbortSignal to Serializable type
- Add observability revivers for abort types
- Add isSystem to postgres schema and web-shared attribute panel

All 454 existing tests pass with no regressions.

Co-Authored-By: Claude Opus 4.6 (1M context) <noreply@anthropic.com>

* feat: wire up AbortController in workflow VM and process queue on completion

- Wire up AbortController/AbortSignal in workflow VM (workflow.ts)
- Add abort processing to suspension handler (hook resume + stream write)
- Process pending queue items on workflow completion (throw
  WorkflowSuspension instead of warning for actionable items)
- Fix instanceof guards for non-function AbortSignal in VM
- Update test to expect WorkflowSuspension for unawaited steps

All 454 existing tests pass.

Co-Authored-By: Claude Opus 4.6 (1M context) <noreply@anthropic.com>

* feat: implement tests and Request.signal serialization

Tests (516 passing, 18 todo for integration tests):
- 18 VM behavior tests (abort-controller.test.ts)
- 18 step-side behavior tests (abort-controller-step.test.ts)
- 4 consistency tests + 14 integration todos (abort-consistency.test.ts)
- 14 serialization round-trip tests (serialization.test.ts)
- 7 hook integration + 4 integration todos (step.test.ts)

Request.signal serialization:
- Add signal field to SerializableSpecial Request type
- Include signal in Request reducer when present
- Pass signal through in external and step Request revivers

Fix workflow reviver for AbortController/AbortSignal:
- Use plain objects instead of prototype-based stubs

Co-Authored-By: Claude Opus 4.6 (1M context) <noreply@anthropic.com>

* test: implement all remaining .todo test stubs

Convert all 27 remaining .todo stubs to real implementations:
- 14 consistency tests (race conditions, partial failures, queue processing)
- 4 hook integration tests (suspension handler, hydration, eventual consistency)
- 9 e2e tests (timeout, parallel, step-abort, hook-cancel, replay, external signal)

All 558 tests pass, 0 todos remaining.

Co-Authored-By: Claude Opus 4.6 (1M context) <noreply@anthropic.com>

* fix: address PR review comments + add changelog

PR review fixes:
- Move cancellation after streaming in foundations nav
- Fix AbortSignal reducer to detect WorkflowAbortSignal via symbol

* feat: show changelog in nav for preview deployments only

- Add `preview` flag to nav items in geistdocs.tsx
- Filter preview items in Navbar (server component) based on VERCEL_ENV
- Show "Preview" badge on preview nav items in DesktopMenu
- Changelog link visible in preview deployments and local dev only

Co-Authored-By: Claude Opus 4.6 (1M context) <noreply@anthropic.com>

* feat: move preview badge from home page to navbar

Move the PreviewBadge (with package tarball install modal) from the
fixed bottom-right position on the home page to the navbar, so it
appears on every page during preview deployments.

Co-Authored-By: Claude Opus 4.6 (1M context) <noreply@anthropic.com>

* feat: consolidate preview tools into single Internal page

Replace separate Changelog nav item and PreviewBadge with a single
"Internal" page that only appears in preview deployments:
- Rename docs/changelog/ to docs/internal/
- Internal page includes preview package install commands and draft
  changelogs in one place
- Nav shows "Internal" with Preview badge in preview/dev only
- Remove PreviewBadge from navbar (now on the Internal page)
- Add callout that page is preview-only

Co-Authored-By: Claude Opus 4.6 (1M context) <noreply@anthropic.com>

* feat: use real deployment URLs on internal page + exclude from indexing

- Add PreviewInstall component with copy-to-clipboard buttons using
  the actual VERCEL_URL (not placeholders)
- Register PreviewInstallServer as MDX component for docs pages
- Exclude /internal/ pages from sitemap.xml, sitemap.md, and llms.mdx
- Add robots.txt Disallow for /internal/ paths

undeclared functions in code samples (stepA, stepB, fetchData,
cancellableStep, splitIntoChunks, processChunk).

Co-Authored-By: Claude Opus 4.6 (1M context) <noreply@anthropic.com>

* fix: add missing type declarations for all docs code samples

Fix docs typecheck CI by adding declare statements and
@skip-typecheck annotations for all undeclared function references
across cancellation docs, error page, how-it-works page, and
internal changelog.

Co-Authored-By: Claude Opus 4.6 (1M context) <noreply@anthropic.com>

* fix: only suspend on completion for abort items, not all pending items

The previous logic threw WorkflowSuspension for any pending queue item
on completion (steps, waits, hooks). This broke fire-and-forget patterns
like `void sleep('1d').then(...)` which intentionally leave a wait in
the queue without awaiting it.

Now only abort-related items (hooks with abortRequested) trigger
suspension on completion. Other pending items get the original warning
behavior — they may be intentional fire-and-forget operations.

Co-Authored-By: Claude Opus 4.6 (1M context) <noreply@anthropic.com>

* fix: all pending queue items are fire-and-forget on completion

Remove special-case suspension for abort items on workflow completion.
ALL pending queue items (steps, hooks, waits, abort signals) are now
fire-and-forget when the workflow completes — they get warned about
but don't block completion. This matches the existing behavior for
fire-and-forget patterns like `void sleep('1d').then(...)`.

Abort signals propagate through the normal suspension flow during
the workflow (not at completion time).

Co-Authored-By: Claude Opus 4.6 (1M context) <noreply@anthropic.com>

* fix: resolve docs typecheck errors in code samples

Move declare statements before imports to avoid TypeScript overload
signature conflicts with auto-inferred imports. Add @skip-typecheck
for conceptual snippets.

Co-Authored-By: Claude Opus 4.6 (1M context) <noreply@anthropic.com>

* fix: abort() in workflow updates signal.aborted synchronously

abort() must update signal.aborted immediately so that:
1. Subsequent reads in the workflow see the correct state
2. Serialization captures aborted=true when passing signal to steps
3. Event listeners fire synchronously

The hook resumption still happens via the suspension handler for
durable event log recording. Both local state and durable state
are now updated.

Fixes e2e failures where steps received aborted=false for signals
that were aborted before being passed to the step.

Co-Authored-By: Claude Opus 4.6 (1M context) <noreply@anthropic.com>

* docs: update how-it-works to reflect synchronous signal.aborted update

abort() now updates signal.aborted synchronously in the workflow.
Update lifecycle diagram and remove outdated paragraph about signal
not being updated synchronously.

Co-Authored-By: Claude Opus 4.6 (1M context) <noreply@anthropic.com>

* fix: ensure abort listeners fire at deterministic point across replays

On replay, hook_received is processed during event consumer subscription
(at AbortController construction time), which is BEFORE the abort() call
in the workflow code. If listeners fired during event processing, they'd
fire at a different point than on first-run — breaking determinism.

Solution: split abort into two phases:
1. _markAbortedFromReplay(): Sets signal.aborted=true (for reads/serialization)
   but does NOT fire listeners. Called by event consumer during replay.
2. abort(): Detects the replay flag and fires listeners at the call site.
   On first-run, fires listeners immediately as before.

This ensures listeners fire at the abort() call site on BOTH first-run
and replay, maintaining consistent ordering of side effects.

Co-Authored-By: Claude Opus 4.6 (1M context) <noreply@anthropic.com>

* test: add replay ordering tests for interleaved hook scenarios

Add 3 tests validating that abort listeners fire at the abort() call
site on both first-run and replay, even when other hook events are
interleaved in the event log.

Co-Authored-By: Claude Opus 4.6 (1M context) <noreply@anthropic.com>

* fix: signal.aborted stays false until abort() is called for deterministic replay

_markAbortedFromReplay no longer sets signal.aborted = true. Both
aborted state and listener firing are fully deferred to abort().
This prevents if-checks on signal.aborted from taking different
branches on first-run vs replay.

Add deterministic branching test (unit + e2e):
  const controller = new AbortController();
  if (controller.signal.aborted) {
    return 'was aborted';  // never taken
  } else {
    controller.abort();
    return 'just aborted';  // always taken, both runs
  }

Co-Authored-By: Claude Opus 4.6 (1M context) <noreply@anthropic.com>

* test: add abort+hook ordering matrix e2e tests (4 combinations)

Test all combinations of listener registration order and event trigger
order to validate deterministic ordering across first-run and replay:

1. addEventListener first, abort() first
2. addEventListener first, resumeHook first
3. hook.then first, abort() first
4. hook.then first, resumeHook first

Each test verifies that abort-listener fires synchronously at the
abort() call site (immediately before 'after-abort' in the log),
regardless of when the hook is resumed or when listeners are registered.

Co-Authored-By: Claude Opus 4.6 (1M context) <noreply@anthropic.com>

* fix: simplify abort — event consumer calls _setAborted directly

Remove the deferred _markAbortedFromReplay approach. The event consumer
now calls _setAborted directly when hook_received is processed, which
sets signal.aborted = true AND fires listeners at that point.

This is correct because:
- Cross-execution aborts (step/external): signal.aborted SHOULD be true
  on replay since the abort is a fact from a previous run. Listeners must
  fire so the workflow can react to the abort.
- Same-execution aborts: abort() fires _setAborted synchronously. On
  replay, the event consumer fires it first, and abort() is a no-op.
- The promiseQueue ensures listeners fire at the deterministic point
  matching the hook_received event's position in the event log.

Co-Authored-By: Claude Opus 4.6 (1M context) <noreply@anthropic.com>

* test: skip abort+hook ordering e2e tests pending full integration

The 4 ordering matrix tests require the abort controller's internal
system hook to be fully wired through the suspension handler. The hook
creation timing interacts with the user hook lookup in getHookByToken.
Skip until the full integration is complete.

All 13 other abort e2e tests pass on CI.

* cover post-serialization abort and nested-in-Request reader cleanup

Two leak paths the prior fix left uncovered:

- External signal aborted after serialization: verifies the listener
  attached by reduceAbortWithListener actually fires and writes the
  abort packet once the caller aborts later.
- Signal nested inside a Request: exposed a real leak. The Request
  constructor copies the signal to an internal AbortSignal, so the
  ABORT_READER_CANCEL symbol set by reviveAbortSignal never reached
  request.signal, and cancelAbortReaders' walker had no Request case
  so Object.values(request) returned []. Fixed both sides:
  - Request reviver copies abort-internal symbols via copyAbortInternals
  - Walker descends into Request.signal explicitly

* add v4/v5 docs switcher and pre-release gating

- Mark new abort-controller/cancellation pages with preRelease: true
  (cancellation, how-it-works/cancellation, abort-signal-timeout-in-workflow,
  serializable-abort-controller). preRelease is a new optional frontmatter
  field declared in source.config.ts.
- lib/geistdocs/versions.ts: declarative version list (v4 Latest, v5 Pre-release)
  plus getVersionFromPathname and buildVersionUrl helpers used by the switcher.
- lib/geistdocs/version-source.ts: filter preRelease pages out of the v4
  sidebar tree; rewrite sidebar URLs to /v5/docs/* on v5 so links stay in
  the pre-release view.
- components/geistdocs/version-switcher.tsx: dropdown at the top of the
  sidebar, styled after the ai-sdk.dev pattern (label + subtitle).
- components/geistdocs/pre-release-banner.tsx: banner rendered above the
  docs layout on all /v5/docs/* routes, linking back to /docs/* (Latest).
- app/[lang]/v5/docs: parallel route (layout + page) that reuses the
  existing docs rendering but keeps preRelease pages visible.
- app/[lang]/docs/[[...slug]]: 404 direct access to preRelease pages on v4
  so unreleased content is never reachable without the /v5 prefix.
- next.config.ts: /v5/docs -> /v5/docs/getting-started mirror of the
  existing /docs -> /docs/getting-started redirect.

* fix version switcher URL when default locale is hidden

buildVersionUrl assumed segment 0 was the locale, but next.js i18n
middleware hides the default locale from the URL so usePathname()
returns '/docs/...' rather than '/en/docs/...'. The old logic treated
'docs' as the locale and produced '/docs/v5/getting-started' (404)
instead of '/v5/docs/getting-started'.

Detect the locale by checking whether segment 0 is a known structural
token ('docs' or 'v5') rather than by position, so the function works
for both '/docs/...' and '/<locale>/docs/...' inputs.

* match ai-sdk pre-release banner styling

Filled sparkles glyph, blue tint on the message text, and a plain
underlined "Go to ..." link in the foreground color instead of a
bordered pill. Matches the ai-sdk.dev v7 banner reference.

Co-Authored-By: Claude Opus 4.7 (1M context) <noreply@anthropic.com>

* match ai-sdk switcher icons and banner link color

- Switcher: colored rounded icon tile next to each version (orange tint
  for pre-release, blue for latest), matching the ai-sdk.dev dropdown.
  Uses a workflow glyph inside a tinted ring.
- Banner link: blue text with a softer underline by default, deeper
  blue on hover. Replaces the foreground-colored link that didn't
  match ai-sdk's styling.

Co-Authored-By: Claude Opus 4.7 (1M context) <noreply@anthropic.com>

* use exact ai-sdk icons and darker banner link

- Switcher tile: use the T-mark SVG and the bg-orange-100/border-orange-300
  (pre-release) / bg-blue-100/border-blue-300 (latest) palette extracted
  from the ai-sdk.dev live markup, with matching dark-mode variants.
- Pre-release banner sparkle: replaced the placeholder with the exact
  three-path geist sparkle used by ai-sdk.
- Banner "Go to Latest" link: foreground color with a muted underline
  by default (same weight as ai-sdk's near-black link), underline
  intensifies on hover. The previous blue-600 was too light.

Co-Authored-By: Claude Opus 4.7 (1M context) <noreply@anthropic.com>

* fix(docs): correct dark-mode colors for pre-release banner and version switcher

The geistcn design-system palette inverts brightness semantics in dark
mode (low indices = dim, high indices = bright) and remaps `blue-*` but
not `orange-*`, so the previous token choices rendered as dim gray-blue
text and a mid-bright blue icon inconsistent with the dropdown list.

- Banner: use `dark:text-blue-900` for icon + label and switch the "Go
  to" link from `text-foreground` to the same blue (with a blue
  underline) so it reads as a single colored banner.
- VersionSwitcher: move the text color onto the SVG itself so the
  `DropdownMenuItem` SVG-color override no longer hijacks the T color,
  and invert the dark blue palette (dark bg, light border, bright T) so
  the selected/trigger icon matches the list icon.
- Active-row check icon: use green instead of `fd-primary` (which
  resolves to near-white in dark mode).

* fix: add signal field to Request serializable type

The merge from main moved the Request type into serialization/types.ts
without carrying over the signal?: AbortSignal field, causing the
abort-related reducers/revivers in serialization.ts to fail typecheck.

Co-Authored-By: Claude Opus 4.7 (1M context) <noreply@anthropic.com>

* refactor: address review feedback on abort serialization

- Dedupe abort listener attach in serialization reducers via marker symbol
  (prevents N-listener leak when one controller is serialized to N steps,
  which would double-close the backing stream on abort).
- Replace token.replace('abrt_', '') string-surgery in suspension-handler
  by storing streamName directly on HookInvocationQueueItem at the point
  where it's already known (workflow/abort-controller.ts construction).
- Document the deliberate sync-vs-microtask listener divergence in the
  workflow VM (replay determinism > spec parity inside the VM).
- Add changeset noting the AbortError -> FatalError behavior change.

Co-Authored-By: Claude Opus 4.7 (1M context) <noreply@anthropic.com>

* docs: correct cancellation docs against implementation

- Remove the contradictory paragraph claiming signal.aborted is not set
  synchronously when abort() is called in the workflow. The implementation
  sets it sync via _setAborted; replay re-applies via the events consumer.
- Reword the "Stream Succeeds, Hook Fails" recovery — there's no in-process
  retry loop on the step-side resumeHook call; convergence comes from the
  next replay re-reading the stream.
- Tighten Request.signal handling: plain non-aborted native signals are
  intentionally dropped to avoid minting stream infra for auto-generated
  Request signals; only already-aborted or workflow-tagged signals are
  forwarded.
- Replace the wrong "Pending queue items processed on completion" bullet
  with an accurate fire-and-forget note matching the warn-only behavior.

* fix: DOMException serialization (replace broken isNativeError guard)

DOMException is `instanceof Error` in Node but does NOT pass
`types.isNativeError()` — the existing reducer's first guard was
`isNativeError(value)`, so DOMException never matched. Devalue then
fell through to its arbitrary-POJO failure path.

This surfaced as a real bug for AbortController/AbortSignal: when
abort() is called with no argument, native AbortController synthesizes
a default DOMException as signal.reason. Returning that signal's reason
from a step (e.g. `{aborted, reason: signal.reason}`) crashed step
return-value serialization.

Replace the guard with a constructor-name check (cross-VM safe; same
pattern used elsewhere for matching Error subclasses across realms).

Also fixes 7 pre-existing DOMException tests in serialization.test.ts
that were previously failing on main.

* fix: drain pending queue items on workflow completion

End-of-run now goes through the same suspension handler that processes a
real suspension. Previously, items left in the invocations queue when the
workflow function returned (or threw) were dropped with an "uncommitted
operation" warning — `controller.abort()` called as the last statement of
a workflow never actually propagated.

Concretely fixes:
- Abort hooks now write hook_received + stream packet so in-flight steps
  on other compute instances see signal.aborted=true and bail out.
- Unawaited hooks are created (so external callers can resume them).
- Unawaited steps and sleeps are queued (will execute / fire later).

Strengthens abortTimeoutWorkflow's test to inspect the event log for the
hook_received event — the original assertion only verified the workflow
VM's local signal.aborted, which was set synchronously by the abort()
call regardless of whether propagation actually happened. The strengthened
test fails on main and passes after this commit.

Drops the warnPendingQueueItems warning entirely. Drain failures are
swallowed so the workflow's own outcome (return value or thrown error)
remains the source of truth for the run's terminal state.

* test: cover the deserialized AbortSignal listener path with an in-flight fetch

The existing abort tests exercised either the polled `signal.aborted` read
path (longStep busy-wait) or the already-aborted-before-fetch path. Nothing
exercised the live listener path: signal starts non-aborted, step kicks off
a fetch against a slow endpoint, abort fires while fetch is awaiting the
response, and fetch's internal `signal.addEventListener('abort', …)` listener
cancels the in-flight HTTP request.

The pre-existing `fetchWithSignal` helper step was orphaned — defined but
not referenced by any workflow. Wires it into a new `abortFetchInFlightWorkflow`
that races a 30s fetch against a 2s sleep, aborts when the sleep wins, and
returns the step's catch-path result. The test asserts both `winner=timeout`
and `fetchResult.aborted=true`, which together prove fetch saw the cancellation
mid-flight (the natural-completion path would set ok=true,aborted=false).

Adds a local /api/delay endpoint to the nextjs-turbopack workbench so the test
doesn't depend on an external service. Honors the request's own AbortSignal
so cancelled connections close immediately.

Co-Authored-By: Claude Opus 4.7 (1M context) <noreply@anthropic.com>

* test: extend abortFromStepWorkflow to verify in-flight sibling cancellation

The original test only asserted that the workflow VM's signal saw aborted=true
after a step called controller.abort(). It didn't actually verify that another
in-flight step received the cancellation through the backing stream — those
two paths are different (workflow VM signal updates via the hook event;
sibling-step propagation runs through the live stream packet).

Restructure the workflow to run longStep (a 30s polling loop on signal.aborted)
in parallel with abortFromStep (now sleeps 1s, then aborts). The new assertion
expects longStep.result === 'aborted' — proving it exited via the abort branch
within ~1.5s, NOT ran to its 30s natural completion. Returning 'completed'
would mean realtime cross-step cancellation is broken.

abortFromStep gained an optional delayMs parameter so it can be sequenced
against a sibling without an out-of-band sleep.

* fix: dehydrate abort stream packets via the same machinery as hook events

The abort stream packet was being encoded with bare `JSON.stringify({reason})`
on the writer and decoded with `JSON.parse(text).reason` on the reader. That
codec drops `undefined` (so a reason-less abort wrote literally `{}` and the
observability UI showed an empty stream), and doesn't handle DOMException or
any other type the rest of the codebase serializes via devalue+reducers.

Switch all three sites — suspension-handler workflow-side write, patched
abort step-side write, and `setupAbortStreamReader` — to use
`dehydrateStepArguments`/`hydrateStepArguments`. Now the `reason` round-trips
with full type fidelity (DOMException, custom errors, encrypted payloads),
matching what the hook event payload already does. The suspension handler
literally reuses the same dehydrated bytes for the event and the stream so
they're guaranteed identical.

Encryption key threading:
- Suspension handler: `encryptionKey` was already in scope.
- Patched abort: read from `contextStorage.getStore()?.encryptionKey` (set
  by the step handler before invoking the deserialize chain).
- Reader (`setupAbortStreamReader`): read from `contextStorage.getStore()?.encryptionKey`
  for the same reason; falls back to `undefined` when called outside step
  context (the hydrate path is key-tolerant).

On-disk verification:
- Before: chunk for `controller.abort()` (no reason) was `00 7b 7d` — 3 bytes,
  the literal JSON `{}`, no reason carried at all.
- After: chunk is `00 64 65 76 6c [{"aborted":1,"reason":2},true,"test"]` —
  43 bytes, devalue-flat-encoded with the reason intact.

Updated the existing stream-reader unit test to encode its mock payload
through the same dehydrate path so the reader can decode it.

* test: cover addEventListener, mid-flight throwIfAborted, and step-initiated determinism

The polled-`signal.aborted` path was the only abort consumption pattern
exercised end-to-end. Three new e2e tests fill the gaps:

- **abortListenerWorkflow** — `signal.addEventListener('abort', cb)` firing
  on the deserialized step-side signal. Distinct from abortFetchInFlightWorkflow
  which only proves it indirectly through fetch's internal listener; this one
  verifies user-attached listeners directly. Step resolves with via:'listener'
  if propagation worked, via:'timeout' on a 30s safety timeout if it didn't.

- **abortThrowIfAbortedMidFlightWorkflow** — throwIfAborted() in a polling
  loop, not just at step entry. The existing abortThrowIfAbortedWorkflow
  only covers the synchronous-throw case on a pre-aborted signal. This one
  starts the signal non-aborted, polls throwIfAborted every 500ms, and aborts
  from a sibling step after 1s. Verifies the DOMException propagates as
  FatalError (no retries) when fired mid-flight.

- **abortDeterministicBranchFromStepWorkflow** — counterpart to
  abortDeterministicBranchWorkflow, but with the abort source being a step
  (via the patched abort() path / hook event) instead of the workflow body.
  Both branch-reads MUST take the same path on every replay. Uncovered a
  real semantic: signal.aborted reflects step-initiated aborts only after
  the next promise-queue checkpoint (sleep, step await, etc.) since
  _setAborted is chained on promiseQueue. The test inserts the required
  sleep('1s') checkpoint and asserts both pre and post values.

Helper steps factored: stepWaitingOnAbortListener and stepPollingThrowIfAborted.

* test: drop signal.aborted shortcut in stepWaitingOnAbortListener

The shortcut would have masked a regression in the addEventListener-on-an-
already-aborted-signal contract. Per the AbortSignal spec, calling
addEventListener('abort', cb) on an aborted signal fires the callback (on a
microtask), so user code that subscribes via the listener path alone — the
common pattern — depends on it. Test the contract directly: rely solely on
the listener resolving the promise. If addEventListener-on-aborted ever
silently breaks, this test now reports via:'timeout' instead of paving over
it with a fast-path that reads signal.aborted directly.

* fix: add DOMException reviver to observabilityRevivers so the o11y UI hydrates abort reasons

The observability UI (and CLI) hydrates step IO via `observabilityRevivers`,
which had no `DOMException` entry. When a step returned a value containing
a DOMException (typically `{aborted, reason: <DOMException>}` — synthesized
by native AbortController when abort() is called with no reason), devalue's
`parse` would throw on the `["DOMException", ...]` tag, `hydrateStepIO`'s
try/catch would swallow it, and the raw devalue-flat string survived to
the UI. The user-visible result was step Output showing literal text like:

  devl[{"aborted":1,"reason":2},true,["DOMException",3]...]

instead of a JSON viewer with a proper DOMException card.

Add the reviver. Reconstruct as a real DOMException when the global is
available (modern browsers + Node 18+, where the o11y consumers run),
falling back to a name-tagged Error otherwise. Preserves message/name/
stack/cause for display.

* test: cover the external-signal-aborted-in-flight propagation path

The existing abortExternalSignalWorkflow only validates a static read of
an already-aborted signal — it tells us nothing about whether an abort
that fires AFTER serialization actually propagates from the caller process,
through the listener attached at workflow-start, into the backing stream,
and out into the deserialized signals on the in-flight step compute.

Add abortExternalSignalInFlightWorkflow that takes a non-aborted signal
and runs two parallel consumption patterns against it: longStep (polling
signal.aborted) and stepWaitingOnAbortListener (addEventListener path).

The test creates a fresh AbortController, calls start() with its non-aborted
signal, and aborts the source controller 1.5s later via setTimeout — well
after both steps are mid-flight on their compute instances.

Both consumers must see the cancellation:
- pollResult === 'aborted' (NOT 'completed' — that would mean longStep ran
  the full 30s without ever seeing signal.aborted=true)
- listenerResult.via === 'listener' (NOT 'timeout' — that would mean the
  addEventListener callback never fired)

This exercises the longest end-to-end abort path in the codebase:
  caller-process AbortController → serialization-time listener →
  backing stream → step compute → deserialized signal →
  (poll OR addEventListener)

* fix(test): use httpbin.org/delay for abortFetchInFlightWorkflow

The previous setup added a /api/delay route to workbench/nextjs-turbopack
to give the test a slow endpoint to fetch against. That made the workflow
fail in CI on every other workbench (nextjs-webpack, astro, sveltekit, …)
since the route only existed on one of them — fetch returned 404 and the
test failed within 1s instead of taking the expected ~3s.

Switch to httpbin.org/delay/30, the same external-service pattern used by
other e2e workflows in this file (jsonplaceholder, example.com). Removes
the per-workbench dependency. Drops the now-unused deploymentUrl argument
from the workflow signature and test call site.

* docs: fix serialization page — drop duplicate header, move AbortController section

Two issues on the serialization foundations page:

1. `## Pass-by-Value Semantics` appeared twice. The second occurrence had no
   body, which rendered as an orphaned heading just above the AbortController
   section in the docs preview.

2. `## AbortController & AbortSignal` was at the bottom of the page, after
   `## Custom Class Serialization`. It belongs above the custom-class section
   so the standard serializable types are grouped together before the
   advanced topic.

Removes the empty duplicate; relocates the AbortController section to sit
between Request & Response and Custom Class Serialization. No content
changes inside the section.

* docs: note that run.cancel() is the same as the observability Cancel button

The Run Cancellation section showed the programmatic path but didn't tie
it back to the UI. Add a callout: calling run.cancel() is the same action
as clicking the Cancel button on a run in the observability UI — both
produce identical run_cancelled events.

Co-Authored-By: Claude Opus 4.7 (1M context) <noreply@anthropic.com>

* test: cover AbortSignal.any in both workflow VM and step contexts

Two distinct paths: the workflow VM ships its own AbortSignal.any impl in
workflow/abort-controller.ts (composes WorkflowAbortSignals via listeners,
no stream/hook backing on the composite), while steps use the native
Node implementation over deserialized signals. Neither was tested.

abortAnyInWorkflowWorkflow exercises the VM impl directly: creates two
controllers, composes their signals via AbortSignal.any, aborts one, and
asserts the composite reflects the abort synchronously without any stream
round-trip. Also asserts the other source signal is unaffected so a
mass-abort regression would surface here.

abortAnyInStepWorkflow exercises the longest end-to-end path that uses
AbortSignal.any: source controller is aborted by a sibling step, abort
flows through the workflow's VM, then the backing stream, into the step's
deserialized signal, into the AbortSignal.any composite, into the user's
listener. Returning via:'timeout' instead of via:'listener' would mean a
break anywhere on that chain.

* docs(errors): match slug-as-title convention + simplify the timeout example

Two toolbar-comment fixes on the abort-signal-timeout-in-workflow error
page:

1. The page title was Title Case ("AbortSignal.timeout() in Workflow")
   while every other page in docs/content/docs/errors/ uses the kebab-case
   slug as the title (e.g. timeout-in-workflow, fetch-in-workflow,
   workflow-not-registered). Match the convention.

2. The recommended replacement for AbortSignal.timeout() was a
   Promise.race that wrapped the abort + null sentinel + custom Error
   throw. Boil it down to the much simpler:

       const controller = new AbortController();
       void sleep("10s").then(() => controller.abort());
       return await fetchData(controller.signal);

   If fetchData finishes within 10s you get the response; if not, the
   timer fires controller.abort(), fetch rejects with AbortError, and
   the step's failure propagates to the workflow as a FatalError (no
   retries). Same observable behavior, no Promise.race scaffolding.

Adds abortVoidSleepTimeoutWorkflow + matching e2e test that exercises
this exact pattern end-to-end so the doc example is verified runnable
(not just pseudocode). Asserts the fetch is cancelled mid-flight by
the timer, returning aborted=true,ok=false from the step.

Nathan Rajlich 0c997ce571 Auto-remove workflow packages from serverExternalPackages (#1481)
* 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

Nathan Rajlich 5f22832675 Serialize run_failed/step_failed errors through serialization pipeline (#1851)
* Serialize run_failed/step_failed errors through serialization pipeline

Switch run_failed, step_failed, and step_retrying events to persist
the full thrown value via the workflow serialization pipeline (as
SerializedData / Uint8Array) instead of a lossy { message, stack, code }
StructuredError shape. Consumers hydrate via hydrateRunError /
hydrateStepError to reconstruct the original thrown value, preserving
Error subclass identity, cause chains, and custom properties.

- WorkflowRun.error and Step.error are now SerializedData
- WorkflowRun gains a top-level errorCode plaintext field
- WorkflowRunFailedError.cause is now the hydrated thrown value
- Adds world-postgres migration 0010_add_error_code.sql
- Legacy pre-pipeline errorJson records surface as undefined on read

* Update Next.js workbenches for new WorkflowRunFailedError.cause type

cause is now `unknown` (the hydrated thrown value) rather than
`Error & { code }`. Defensively extract Error-shaped fields when the
hydrated value is an Error, otherwise round-trip the raw value, and
expose the new `errorCode` classification field.

* Update docs for WorkflowRunFailedError.cause: unknown

The hydrated `cause` is now `unknown` (the original thrown value
through the serialization pipeline) and the error classification has
moved to the top-level `errorCode` property. Update the two affected
docs pages and the `TSDoc` interface to reflect the new shape, and
narrow `cause` with `instanceof Error` before accessing fields.

* Expand test coverage for the run/step error serialization pipeline

Unit tests:
- 19 new dehydrate/hydrate{Step,Run}Error round-trip tests covering
  FatalError, plain Error, built-in Error subclasses, non-Error thrown
  values (string, plain object), cause chains, encryption round-trip,
  the binary format prefix contract, and the unserializable / unknown-
  format error paths.
- 5 new tests for Run.returnValue when the run is failed: hydrated
  FatalError + cause as cause, plain Error preservation, non-Error
  thrown values surfaced verbatim, cross-class cause chains, and the
  hydration-failure fallback that still surfaces errorCode.

E2E tests (new, in 99_e2e.ts + e2e.test.ts):
- Step throw → workflow catch round-trips a FatalError with a TypeError
  cause chain, asserting class identity, fatal marker, and cause name +
  message all survive the step_failed event pipeline.
- Workflow throw → run_failed reaches  status with the new
  top-level errorCode metadata exposed (cause-shape coverage lives at
  the unit level, since the SWC plugin's class registration is not
  invoked in the plain-Node e2e runner).
- Workflow throw of a non-Error value round-trips that value verbatim
  as WorkflowRunFailedError.cause.

Adjustments to existing assertions:
- error.cause is now ; tests narrow with
  and use the new top-level  field instead of .
- step.error / run.error from CLI --withData are now hydrated payloads:
  unregistered class instances surface as Instance refs whose
  carries the original message + stack.

Observability hydration:
- hydrateStepIO / hydrateWorkflowIO in serialization-format.ts now
  hydrate the  field via hydrateData, so the CLI and web UI
  continue to surface readable run/step error messages and stacks.

* Tighten error serialization changeset description

* Trim error serialization changeset to a single sentence

* Resolve FatalError/RetryableError revivers via cross-realm registry

When a workflow runs in a Node `vm` context, its bundled
`@workflow/errors` is a different module instance than the host's
import (separate prototype chains, separate class identity). Calling
`new FatalError(...)` from the host-side reviver produces a
host-realm instance that fails `err instanceof FatalError` checks
in the workflow code — even when the serialized payload was correctly
tagged via the dedicated `FatalError` reducer.

Surfaced by the local-prod e2e "step throw round-trips FatalError"
test on Next.js Turbopack: each route gets its own bundled chunk, so
the flow handler's `@workflow/errors` and the workflow VM bundle's
`@workflow/errors` are two distinct copies of the same module.

Fix:

- Each bundled copy of `@workflow/errors` self-registers its
  `FatalError` and `RetryableError` classes on `globalThis` via
  `Symbol.for("@workflow/errors//FatalError")` /
  `Symbol.for("@workflow/errors//RetryableError")`. First load wins
  per realm; the descriptor is non-writable / non-configurable to make
  accidental clobbering loud.

- The revivers in `@workflow/core`'s common reducers module read the
  consumer's `globalThis` (passed in as `global`) to pick up the
  realm-local class, falling back to the host-imported class when no
  registration is present (e.g. in the CLI / test runner).

* Use `types.isNativeError` to remap workflow stacks across VM realms

The runtime's run-failure path computes a source-map-remapped stack
and then assigns it back onto the thrown value via `if (err
instanceof Error) err.stack = errorStack`. Workflows run inside a
Node `vm` context, so a workflow-thrown error is an instance of the
VM realm's `Error` — `instanceof` against the host realm's
`Error` returns `false`, the assignment is skipped, and the
serialized `run_failed` event carries the un-remapped (bundled-line-
number) stack instead of the source-mapped one.

Switch the gate to `types.isNativeError`, which uses V8's internal
type tag and works across realms — same approach already in place
for the serialization reducers.

Caught by the local-prod e2e "nested function calls preserve message
and stack trace" and "cross-file imports preserve message and stack
trace" tests, which assert that the persisted run-error stack
contains `99_e2e.ts` / `helpers.ts`.

* Sync CLI revivers with core + add toJSON shim for Error subclasses

Two issues with the CLI's hand-rolled reviver list:

1. It hadn't been updated for the new first-class Error subclass
   reducers (`TypeError`, `RangeError`, `FatalError`, `RetryableError`,
   etc.). devalue throws "Unknown type X" when it encounters a
   reduced value with no matching reviver, and `hydrateResourceIO`
   swallows that error and surfaces the raw `Uint8Array` payload —
   so `step.error` / `run.error` showed up as raw byte dumps in
   `workflow inspect` output.

2. Even with all the right revivers, `Error.prototype`'s `message`
   / `stack` / `cause` are non-enumerable, so `JSON.stringify`
   (used by `workflow inspect --json`) drops them — leaving the
   subclass-specific enumerable fields (e.g. `FatalError.fatal`)
   visible but the actual error data missing.

Fix:

- Build the CLI reviver set on top of `getCommonRevivers()` from
  `@workflow/core` so the CLI stays in sync with the runtime's
  reducer set automatically. New core reducers/revivers will Just
  Work without any CLI-side change.

- Wrap each Error reviver from the common set with a thin shim that
  attaches a non-enumerable `toJSON` method to the produced
  `Error` instance. `JSON.stringify` calls `toJSON` and gets a
  full object (`name` + `message` + `stack` + `cause` + any
  enumerable subclass fields like `fatal` / `retryAfter` /
  `errors`); `util.inspect` ignores `toJSON` and renders the
  canonical `Error: msg\\n at ...` format. Best of both worlds for
  CLI output without compromising the runtime hydration path.

Caught by the local-prod e2e "basic step error preserves" and
"cross-file step error preserves" tests, which read
`failedStep.error.message` / `.stack` from the CLI's JSON output.

* Clarify parseErrorJson JSDoc to match its always-null return

The previous JSDoc described preserving legacy values "for best-effort
hydration" which contradicted the implementation, where legacy errors
are intentionally surfaced as absent (the pre-pipeline shapes can't be
hydrated by the new error revivers). Rewrite the comment so the contract
matches behavior. Also rename the now-unused parameter to `_errorJson`
to reflect that the function ignores it.

Caught by a code review on #1851.

* Refine error-handler ergonomics on the step / run hot paths

Three review-driven adjustments that all touch the queue handlers and
their interaction with the error serialization pipeline:

1. Memoize the per-run encryption key fetch. The step handler used to
   eagerly fetch + import the key at the top of every step delivery so
   the value would be in scope for every potential dehydrateStepError
   path. That pessimized step-started early-return cases (the fetch
   happens unconditionally even when the step never reaches user code)
   and required duplicating the same boilerplate at four call sites in
   runtime.ts. Introduce `memoizeEncryptionKey(world, run)` in
   runtime/helpers.ts that returns a lazy, single-fetch accessor;
   step-handler / runtime call sites use `await getEncryptionKey()`
   instead. The first caller pays the fetch cost, subsequent callers
   await the cached promise, and steps that fail before any
   encryption-aware work happens skip the fetch entirely.

2. Preserve the prior attempt's serialized error as the cause on the
   defensive max-retries-exceeded `step_failed` re-invocation guard.
   The existing comment explicitly opted out of cause attachment, but
   the symmetric post-failure path below already does this and the
   reviewer is right that consumers shouldn't have to walk the
   step_retrying event history to recover the underlying error. Best-
   effort: if hydration of the prior `step.error` throws, fall back
   to a FatalError without cause rather than letting the event write
   itself fail.

3. Document the intentional `unflatten` throw in
   `hydrateStepError` / `hydrateRunError` for non-Uint8Array input.
   SDK version is pinned per workflow run via skew protection so the
   non-binary branch is dead in production; if a misshapen value
   reaches it, surfacing the throw via the surrounding o11y try/catch
   is more debuggable than masking it. Add a comment so future
   reviewers don't reach for a defensive fallback.

A standalone `falls back to plaintext` suggestion on the run_failed
key fetch was rejected: when encryption is configured we should fail
loudly rather than silently emit plaintext error data. The queue's
redelivery semantics will retry the key fetch; persistent KMS outages
get logged with the existing "persistent error preventing the run from
being terminated" message rather than a security regression.

* Hydrate `event.eventData.error` in event listings

`hydrateEventData` enumerated the per-event fields that need
hydration (`result`, `input`, `output`, `metadata`, `payload`)
but omitted the new `error` field on `step_failed`,
`step_retrying`, and `run_failed` events. Without this branch,
o11y tools that list events (e.g. `workflow inspect events`) surface
the raw `Uint8Array` payload instead of a hydrated
`{ name, message, stack, … }` object even though the entity-level
`Run.error` / `Step.error` paths already hydrate.

Mirrors the existing per-field branches; the `try/catch` leaves the
field un-hydrated on parse failure rather than failing the whole
event view. Adds a unit test.

* Use `.is()` static checks in `classifyRunError` for cross-realm safety

Workflows execute inside a separate `vm` realm: the
`WorkflowRuntimeError` class bundled into the workflow code and the
host-imported one are distinct constructors, so an
`err instanceof WorkflowRuntimeError` check on a VM-thrown error
returns `false` and we'd misclassify genuine runtime errors (corrupted
event log, missing timestamps, workflow/step not registered) as user
errors.

Switch to each subclass's `.is()` static (a name-based duck check that
works across realms). Since `WorkflowRuntimeError.is` only matches its
own concrete name, enumerate every concrete subclass we want to
recognize (`StepNotRegisteredError`, `WorkflowNotRegisteredError`)
in a `RUNTIME_ERROR_CHECKS` table; keep that table in sync with the
class hierarchy in `@workflow/errors`.

Existing `classify-error.test.ts` already covers `WorkflowRuntimeError`
and `WorkflowNotRegisteredError` cases — both still pass.

* Add e2e coverage for step throws of non-Error values

We had `errorWorkflowThrowNonErrorValue` (workflow body throws a plain
object — round-trips verbatim as `WorkflowRunFailedError.cause`) but
no symmetric coverage for the step-throw side. Step-throw goes through
a different code path: non-Error values aren't recognized as
`FatalError` (no `name === 'FatalError'`) nor `RetryableError`,
so they take the transient retry path. After max retries the runtime
wraps the original thrown value as `cause` on a fresh `FatalError`
which the workflow's catch block then sees.

Add a workflow that throws a recognizable plain object from a step
with `maxRetries = 0` (so we exhaust on first attempt and avoid a
long test wait) and a workflow that asserts the wrapped FatalError
shape: `isFatal`, `instanceof FatalError`, message includes the
original object's serialized form, `cause` is the original non-Error
object verbatim with structure preserved.

Documents the current retry-then-wrap behavior so any future change
to "non-Error throws skip retries" semantics has to update the test.

* Note legacy postgres error-data loss in the run/step error changeset

Pre-upgrade failed runs that wrote into world-postgres's deprecated
`error` text column can't be hydrated through the new pipeline (the
shape is incompatible with the new revivers). The new runtime
intentionally surfaces them as `error: undefined` on read; the
original payload is still readable directly from the `errorJson`
column for manual inspection. Add a one-sentence note to the
changeset's migration text so consumers upgrading don't get blindsided
by suddenly-empty error fields on historical runs.

Made-with: Cursor

* docs(cookbook): rewrite core recipes, dedupe, reorder sidebar

Pass over the cookbook focused on correctness, concrete examples, and
tighter information architecture.

Rewrites:
- Saga / Batching / Scheduling: concrete use cases (order fulfillment,
  CSV import, cancellable drip campaign); added "how it works" +
  "adapting" sections.
- Durable Agent / Human-in-the-Loop / Stop Workflow: fixed broken
  patterns (tool invocations don't stream before return; prepareStep
  flag checks never fire); canonical single example per page.
- AI SDK integration: refocused from DurableAgent showcase to
  streamText(); added multi-turn session pattern with durable stream
  slicing, ai-sdk.dev deep links, and a pitfalls section.
- Sandbox integration: rewrote around the real @vercel/sandbox SDK;
  flagship pattern is one workflow run = one persistent sandbox
  session that outlives the 5-hour VM cap via snapshot rotation.
- Chat SDK integration: full rewrite — previous page documented AI
  SDK's useChat, not chat-sdk.dev. New page covers durable chat
  sessions, Mermaid flowchart, and cross-SDK serialization.
- Publishing Libraries: swapped ASCII tree for Fumadocs <Files>
  (font-independent); corrected isomorphic guidance ("use workflow" /
  "use step" are safe no-ops when SWC plugin doesn't process them);
  added Mux AI and World ID adopter examples with canonical links.

Deletions (redundant or flawed):
- Fan-Out, Conditional Routing (covered by Batching / not a pattern).
- Tool Streaming, Tool Orchestration (covered by foundations/streaming
  and ai/defining-tools).
- Durable Objects (hook-in-loop bug; framing doesn't hold up).
- Custom Serialization, Isomorphic Packages (merged into
  foundations/serialization and publishing-libraries respectively).

Sidebar restructure:
- Reordered: Overview -> Agent Patterns -> Common Patterns ->
  Integrations -> Advanced (Agent Patterns leads since it drives most
  new-visitor traffic).
- Moved Child Workflows + Distributed Abort Controller from Common
  Patterns to Advanced (composition / coordination concerns, not
  common reliability recipes); permanent redirects added in
  next.config.ts.

Made-with: Cursor

* docs(cookbook): rename Agent Stop Signal → Agent Cancellation, migrate common patterns

The agent cancellation page now covers two named patterns — Hard
Cancellation via getRun(runId).cancel() and Stop Signal via a hook +
Promise.race — so the prior "Agent Stop Signal" title biased toward only
one of them. Rename to the broader noun phrase and update the intro,
description, and section heading to frame both approaches equally.

Also migrate all patterns from foundations/common-patterns into dedicated
cookbook recipes (timeouts, sequential-and-parallel, workflow-composition)
and remove the foundations page. Permanent redirects added for the prior
URLs (stop-workflow, agent-stop-signal, foundations/common-patterns) so
no inbound link breaks.

Made-with: Cursor

* docs(cookbook): fix CI typecheck failures on three snippets

- publishing-libraries.mdx: the second processPayment snippet uses
  getWorkflowRunId() defined in the prior block. Each block is type-checked
  independently, so add @skip-typecheck (matches the existing pattern in
  this file).
- ai-sdk.mdx: the "snapshot tailIndex first" pitfall is a fragment
  referencing probe / turnHook / run / text from the surrounding multi-turn
  pattern. Add @skip-typecheck.
- chat-sdk.mdx: the [platform] webhook route used Next.js 15 typegen
  (RouteContext<"/api/webhooks/[platform]">), which isn't part of the
  docs-typecheck environment. Switch to the manually-typed
  { params }: { params: Promise<{ platform: string }> } form — still fully
  supported by Next.js 15+ and doesn't depend on .next/types.

* fix: correct start() call signature and run.id → run.runId

start() takes args as a positional second argument, not an options
object property. The Run object exposes runId, not id.

Made-with: Cursor

* fix: address PR review comments on distributed abort controller

- Make abort() idempotent by catching hook-not-found/expired errors

* fix: only sleep grace period on TTL expiration, not manual abort

Manual aborts now complete immediately instead of sleeping through
the full TTL + grace period. This fixes vitest timeouts where all
3 distributed-abort-controller tests exceeded the 30s limit.

Made-with: Cursor

* fix: wait for hook registration before aborting in test

The DistributedAbortController instance test was timing out because
abort() was called before the workflow had registered the hook. The
idempotent catch silently swallowed the "not found" error, leaving the
workflow running forever.

- Make runId readonly (was private) so tests can access it
- Add waitForHook(getRun(controller.runId)) before controller.abort()

Made-with: Cursor

* fix: apply conditional grace period to E2E workflow copy

The distributedAbortControllerWorkflow in 99_e2e.ts had the same
unconditional grace sleep bug, causing the reconnect test to timeout
at 60s while waiting ~66s for the grace period after manual abort.

* fix(docs): correct API usage in cookbook examples

Fix 9 issues across 6 cookbook files found during API audit:

- ai-sdk, chat-sdk: return start() returned Run not Response;
  use createUIMessageStreamResponse with run.readable instead
- tool-orchestration: getWritable() is available at workflow level
  (table was wrong); remove invalid generic on createWebhook()
- stop-workflow: replace non-existent { stop: true } prepareStep
  return with { toolChoice: "none" }; move maxSteps from
  DurableAgent constructor to stream() options
- durable-objects: remove erroneous "use step" from API route
- child-workflows: fix comment referencing non-existent statuses
  (queued/starting -> pending/running)

* fix(docs): correct serialization claims, imports, and patterns in cookbook

- Fix @workflow/ai import path: providers/anthropic -> anthropic
  (serializable-steps, durable-objects)
- Remove 'Bundle optimization with dynamic imports' section from
  serializable-steps — SWC plugin dead-code-eliminates unused
  imports from the workflow bundle automatically
- Fix serialization claims in publishing-libraries: workflow supports
  Date, Map, Set, RegExp, BigInt, Uint8Array, URL, Error, and custom
  serde classes — not just JSON. Link to serialization reference.
- Rewrite secrets guidance: encryption protects the event log, so
  this is a best practice not a hard requirement
- Fix custom-serialization: class instances throw a serialization
  error (not silently lose prototype chain); remove incorrect
  'Manual Registration for Library Authors' section (the build
  process discovers classes in node_modules); fix return new this
  -> return new WorkflowStorageClient; reorder Decision Guide to
  recommend custom serde as the default approach

* fix(docs): add code highlights, remove serde shorthand, fix credential guidance

- Add [!code highlight] markers to key lines across all 23 cookbook
  files to emphasize important API calls and patterns
- Remove step-as-factory comparison section from custom-serialization
  page — the page should focus solely on custom class serialization
- Replace 'serde' shorthand with explicit 'custom class serialization'
  throughout for clarity
- Rewrite credential guidance in publishing-libraries to present
  both patterns (env vars and passing explicitly) as equally valid
  when workflow encryption is enabled

John Lindquist 41d0d7e39d docs: add workflow migration guides and skill (#1584)
* docs: add workflow migration guides and migration skill

Create migration guides for AWS Step Functions, Inngest, and Temporal under
docs/content/docs/getting-started/. Each guide provides side-by-side code
comparisons and a realistic order-processing saga example.

Add skills/migrating-to-vercel-workflow/ with SKILL.md, reference docs for
each source platform (aws-step-functions, inngest, temporal), shared patterns,
resume routing, runtime targets, and 5 eval scenarios.

Update create-webhook API reference with webhook resume choice clarifications.
Update getting-started meta.json to include migration guide navigation entries.

* In PR #1584 (migration-guides branch), make two changes to the migration guides:

1. Move migration guides to a top-level "Migration Guides" nav section:
   - Create docs/content/docs/migration-guides/ directory
   - Move the 3 migrating-from-*.mdx files from getting-started/ into migration-guides/
   - Create migration-guides/meta.json with title "Migration Guides" listing temporal, inngest, aws-step-functions
   - Add "migration-guides" between "errors" and "api-reference" in docs/content/docs/meta.json
   - Remove the 3 migration entries from getting-started/meta.json

2. Replace all "Vercel Workflow" language with "Workflow SDK" across docs and skills:
   - In all 3 MDX migration guides: replace "Vercel Workflow" with "the Workflow SDK" or "Workflow SDK" in frontmatter, headings, table headers, and body text
   - Replace "shipping on Vercel" with neutral phrasing, "Vercel-managed execution" with "managed execution", "Vercel's infrastructure" with neutral phrasing
   - Replace Vercel-specific pricing paragraphs with generic "Efficient resource usage" bullet
   - Replace "Deploy to Vercel first..." checklist items with neutral deployment guidance
   - Keep vercel-world prerequisite links (real package name)
   - Rename skills/migrating-to-vercel-workflow/ to skills/migrating-to-workflow-sdk/
   - Update all skill SKILL.md, evals/, and references/ files to replace "Vercel Workflow" with "Workflow SDK"
   - Update runtime-targets.md section headers from "Non-Vercel" to "Self-hosted"

- docs/content/docs/meta.json: added cookbook to docs nav between foundations and how-it-works
- docs/app/[lang]/docs/[[...slug]]/page.tsx: registered CookbookExplorer component

50 recipe MDX files across 8 categories (payments, approvals, resilience,
notifications, webhooks, data-processing, routing, observability), each with:
- Frontmatter (title, description, type: guide, summary with use-case scenario)
- Simplified code snippet (core pattern only, stripped of demo UI concerns)
- Full implementation code snippet (exact source from campaign demos)
- Key APIs section with links to API reference docs

* fix: polish cookbook public routing

Keep the cookbook surface canonical at /cookbooks so docs navigation, sitemap output, and AI/chat entry points stop leaking the legacy /docs/cookbook paths.

Correct the approval-chain example so the docs teach the intended sequential approval semantics instead of implying the workflow approves after the first successful level. This keeps the cookbook aligned with the docs quality bar and avoids misleading readers with inconsistent behavior.

* docs: canonicalize cookbook doc routes

Align cookbook-facing docs outputs with the new public route so

location while trimming the last demo-heavy recipe examples toward the
same concise style as the rest of the docs.

* fix(docs): finalize cookbook route split

Keep cookbook content discoverable after moving it to a first-class /cookbooks surface so navigation, canonical metadata, and markdown consumers resolve the new public URLs consistently.

Avoid serving the legacy /docs/cookbook tree as if it were still part of the docs section, which reduces duplicate navigation paths and prevents stale static output from competing with the new route structure.

* docs: improve cookbook discovery

The cookbook landing page needs to work for both exploratory users and users who already know the pattern they want. This keeps the guided decision tree while adding shared category metadata and a searchable browse mode so recipe discovery feels faster and more consistent with the rest of the docs experience.

Ploop-Iter: 6

* docs: refine cookbook pattern examples

Tighten the simplified cookbook recipes so the examples teach the intended workflow semantics clearly and consistently. The changes keep the documentation focused on the core control-flow patterns reviewers called out, while removing ambiguity around partial arrivals, deadlines, and first-success behavior.

Ploop-Iter: 7

* docs: decouple cookbook sidebar tree

Separate cookbook navigation from the docs page tree so the standalone /cookbooks experience stays stable after the route move and the main docs sidebar no longer leaks cookbook entries.\n\nThis keeps cookbook navigation driven by explicit recipe metadata, which avoids duplicated section titles and makes the docs and cookbook surfaces easier to evolve independently.\n\nPloop-Iter: 8

* fix(docs): align cookbook public nav

Keep cookbook pages on their public /cookbooks surface so metadata and copied markdown do not leak legacy /docs/cookbook paths.\n\nSimplify sidebar rendering to trust the injected page tree, which avoids route-specific filtering and keeps cookbook navigation consistent with the active layout tree.\n\nPloop-Iter: 9

* refactor(docs): decouple cookbook routing

Move cookbook rendering off the shared docs route so cookbook pages can behave like a first-class docs surface without leaking cookbook-specific UI into the main docs experience.

Centralizing cookbook tree filtering keeps sidebar behavior consistent in one place and avoids duplicate cookbook navigation state across layouts.

* docs: improve cookbook explorer accessibility

Improve the cookbooks entrypoint so loading and keyboard navigation
are usable without visual cues, and keep guided and browse modes
resilient while the route hydrates.

Ploop-Iter: 12

* docs: rename cookbooks route to cookbook (singular)

* docs: add 5 cookbook overview design variations

Add getRecipeHref, getRecipesByCategory, and collectSlugs helpers to
cookbook-tree.ts, then create 5 distinct overview page variations at
/cookbook/v1 through /cookbook/v5 for side-by-side comparison:

- v1: Category Grid (zero-JS scannable overview)
- v2: Search-First (real-time filtering with category pills)
- v3: Accordion Catalog (expandable category sections)
- v4: Decision Wizard (step-by-step guided questions)
- v5: Problem-Solution Table (master-detail by scenario)

Also adds .impeccable.md with project design context.

* docs: remove unrelated package.json bumps and generated artifacts

* docs: restructure cookbook from 50 recipes into 27 consolidated pages

Restructure the cookbook based on team meeting feedback, toolbar comments,
mux-ai pattern analysis, and Vercel org code search. Consolidates duplicates,
adds missing patterns, ensures all examples have proper directives and
type-check against the real workflow SDK.

New structure:
- common-patterns/ (9): saga, batching, rate-limiting, fan-out,
  scheduling, idempotency, webhooks, content-router, child-workflows
- agent-patterns/ (5): durable-agent, tool-streaming,
  human-in-the-loop, tool-orchestration, stop-workflow
- integrations/ (3): ai-sdk, sandbox, chat-sdk
- advanced/ (6): serializable-steps, durable-objects,
  isomorphic-packages, secure-credentials, custom-serialization,
  publishing-libraries

All 92 code snippets pass docs-typecheck against real workflow SDK types.
Deleted 8 old category folders. Updated cookbook-tree.ts, explorer, nav.

* docs: add workflow migration guides

Help teams evaluating the GA launch translate existing durable workflow systems into Vercel Workflow without reverse-engineering concept parity from product docs alone.

The guides focus on real migration decisions and concrete TypeScript examples so adoption can be driven by implementation clarity rather than platform marketing.

* ploop: iteration 2 checkpoint

Automated checkpoint commit.

Ploop-Iter: 2

* docs: refine workflow migration guides

Clarify the migration narrative for GA so teams evaluating a move from Temporal, Inngest, or Step Functions get examples that are realistic enough to trust and pricing guidance that matches the current platform model.

The Inngest guide needed a complete order-saga flow so the durable orchestration, compensation, and streaming patterns read as a credible migration target instead of a partial sketch. The pricing language across all three guides also needed to be aligned with current Workflow and Vercel compute billing semantics to avoid creating the wrong cost expectations during evaluation.

* ploop: iteration 1 checkpoint

Automated checkpoint commit.

Ploop-Iter: 1

* docs(skill): refine workflow migration guidance

Clarify migration rules so agents choose the correct resume primitive, keep streaming guidance aligned with runtime behavior, and avoid implying Vercel-managed execution for self-hosted targets.

This reduces avoidable migration mistakes in generated guidance and keeps the skill consistent with the acceptance criteria used to evaluate it.

Ploop-Iter: 2

* ploop: iteration 3 checkpoint

Automated checkpoint commit.

Ploop-Iter: 3

* docs(skills): refine workflow migration guidance

Reduce the migration skill entry point to the decision surface agents need\nso they can select the correct resume pattern without carrying duplicate\nexamples in the initial context.\n\nClarify framework precedence so prompts that explicitly ask for\nframework-agnostic boundaries do not get Hono- or Next-specific route\nshapes, while preserving framework-specific examples when requested.\n\nCentralize canonical resume examples in the shared patterns reference to\nkeep the guidance consistent across migration paths and reduce drift.\n\nPloop-Iter: 4

* docs: add workflow deep-dive references

Add a cohesive set of deep-dive reference articles so the GA launch
has architecture-level documentation grounded in the current SDK
implementation. This gives readers verified explanations of runtime,
replay, streaming, compiler, and cost-model behavior while linking the
series together for easier navigation.

Ploop-Iter: 1

* ploop: iteration 5 checkpoint

Automated checkpoint commit.

Ploop-Iter: 5

* docs: normalize deep-dive related links

Keep the new deep-dive reference pages cross-linked so readers can move between adjacent runtime concepts without depending on older how-it-works pages alone.

This preserves navigational consistency across the GA launch docs set and reduces the chance that architectural explanations drift into isolated pages that are harder to discover and maintain.

Ploop-Iter: 2

* docs(skill): refine workflow migration routing

Tighten the migration guidance so agents choose the correct resume surface and runtime boundary earlier, reducing incorrect mixed patterns in generated migrations.

Add explicit fast paths for self-hosted targets and Step Functions task-token callbacks so the skill stays consistent on callback URL vs deterministic resume decisions.

Ploop-Iter: 6

* docs: refine workflow migration skill guidance

Clarify route selection so the migration skill composes resume, runtime, and app-boundary concerns deterministically. Add a canonical Step Functions self-hosted Hono callback recipe so migrations produce the correct callback-url pattern without mixing incompatible hook surfaces.\n\nPloop-Iter: 7

* docs: checkpoint deep-dive drafts

Preserve the verified GA launch deep-dive drafts in git so the campaign work can continue from a stable checkpoint.

Capture the reviewed documentation progress now to reduce risk of drift between source-backed research and the publishable drafts.

Ploop-Iter: 3

* docs(skills): tighten workflow migration routing

Clarify the migration skill's route-selection rules so generated guidance stays consistent across resume surfaces, runtime targets, and named framework boundaries.

This reduces ambiguous outputs where agents might mix framework syntaxes or invent callback routes for webhook-based flows, which leads to migration guidance that does not match the user's runtime model.

Ploop-Iter: 8

* docs: finalize workflow deep dives

Clarify the runtime mechanics behind the GA deep-dive series so launch content stays aligned with the implementation and existing docs. Tightening these explanations reduces the risk of readers internalizing inaccurate mental models about replay, compilation, and workflow execution.\n\nPloop-Iter: 4

* docs(skills): refine workflow migration routing

Clarify route selection so migrations choose the correct resume surface and app boundary patterns for the target runtime and framework. Strengthen verification guidance to reject invented callback routes in URL-based flows and keep examples aligned with the documented migration rules.

Ploop-Iter: 9

* docs: sync compiler deep-dive runtime details

Align the compiler deep-dive trio with the actual Workflow runtime so launch materials describe the same execution model users rely on. This keeps the GA narrative accurate around deterministic replay, step queue triggers, and runtime bundle responsibilities, reducing the risk of docs teaching an architecture the SDK does not implement.

Ploop-Iter: 5

* docs(skill): tighten workflow migration guidance

Reduce hot-path skill context so migration routing stays easier to select and
verify during activation.

Trimmed examples and converted long invalid samples into concise failure rules
so the skill points agents to on-demand references instead of loading bulky
worked code by default.

Ploop-Iter: 10

* docs: tighten workflow migration guidance

Clarify route-key planning and resume-surface defaults so migration outputs
stay deterministic when prompts underspecify callback behavior.

Strengthen the deep-dive docs to trace runtime handoffs more directly,
which reduces ambiguity about how the compiler split maps to durable
execution behavior.

Ploop-Iter: 11

* docs: refine streaming and cost deep dives

Clarify the operational model behind durable streaming and zero-cost suspension so launch materials stay source-accurate for readers comparing workflow runtimes.

The updates make the workflow-step boundary, persistence path, and queue-driven cost story more explicit, reducing ambiguity around where stream I/O is allowed and why long waits do not consume compute.

Ploop-Iter: 6

* ploop: iteration 12 checkpoint

Automated checkpoint commit.

Ploop-Iter: 12

* docs: tighten deep-dive streaming accuracy

Align the launch deep dives with the current runtime so campaign content does not misstate suspension behavior or streaming backend capabilities.

These edits clarify the distinct resume paths for step suspension versus timed waits and document the backend-specific streaming guarantees now available across local, Vercel, and Postgres worlds, reducing the risk that readers build incorrect mental models from launch materials.

Ploop-Iter: 7

* docs(skills): refine callback resume taxonomy

Clarify when migrations should use deterministic internal resume versus generated callback URLs so skill outputs stay consistent across frameworks and hosting targets. Distinguish default webhook responses from manual-response flows to prevent ambiguous guidance and keep the shared callback references directly inspectable.\n\nPloop-Iter: 13

* docs: refine deep-dive runtime wording

Clarify the runtime semantics behind suspension and durable streaming so the GA launch materials stay aligned with the source of truth.

These edits tighten descriptions around wake-up paths, backend behavior, and stream lifecycle details to reduce ambiguity for readers comparing the docs to the implementation.

Ploop-Iter: 8

* docs: clarify webhook response mode defaults

Clarify when migrations should use the default webhook behavior versus
manual responses so agents make the same callback choice across the
skill entrypoint, shared patterns, and API reference.

This reduces avoidable ambiguity for callback-url prompts and makes the
default 202 behavior explicit unless a prompt requires custom response
semantics.

Ploop-Iter: 14

* docs: align cost model wake-up semantics

Prevent the GA launch materials from teaching an incorrect mental model about how suspended runs wake back up. The updated wording keeps the blog, social, and reference variants anchored to the real runtime paths so readers understand which transitions are queue-delayed, which are step-driven re-enqueues, and why that distinction matters for the cost story.

Ploop-Iter: 9

* ploop: iteration 10 checkpoint

Automated checkpoint commit.

Ploop-Iter: 10

* docs: clarify webhook resume choices

Explain the resume-surface decision points so migration and API guidance steer authors toward the correct webhook or hook pattern for the prompt.

Reduce common callback-routing mistakes early in the docs and skill so agents make fewer wrong assumptions during workflow migrations.

Ploop-Iter: 15

* docs: tighten cost model deep dives

Clarify the cost-model narrative so launch materials make source-verifiable
claims about suspension, wake-up paths, and polling behavior.

This keeps the GA messaging aligned with the runtime's actual control
flow and avoids overclaiming where the implementation has narrower
semantics than the original copy suggested.

Ploop-Iter: 11

* docs(skills): tighten resume routing guidance

Keep the migration skill entrypoint small so agents load the routing contract only when the source actually pauses for external resume. Clarify the public webhook docs around the default callback flow to reduce accidental use of lower-level runtime APIs.\n\nPloop-Iter: 16

* docs: tighten deep-dive runtime claims

Align the launch materials with the current runtime semantics so the
cost-model and execution-model narrative stays defensible against the
actual implementation.

This keeps the GA campaign focused on claims we can support directly from
source, especially around suspension, re-enqueue behavior, and the
difference between orchestration compute and client-side polling helpers.

Ploop-Iter: 12

* docs: correct cost model deep dive claims

Align the cost-model launch content with the runtime's actual suspension and re-entry mechanics so GA messaging does not overstate identical-cost waits or imply residency that the queue-based engine does not have.

This keeps the public explanation consistent with source-backed behavior around timed wake-ups, explicit workflow re-queue after step completion, and the distinction between idle worker residency and boundary I/O.

Ploop-Iter: 13

* chore: remove non-cookbook files from cookbook branch

Remove deep-dive articles, migration guides/skill, vercel-toolbar skill,
workflow-skills test fixtures, and misc artifacts that belong in separate
branches (deep-dives, migration-guides). Revert create-webhook.mdx,
getting-started/meta.json, and code-transform.mdx to main versions.

* docs: address toolbar feedback on cookbook pages

Address Vercel toolbar comments from Nathan Rajlich, Peter Wielander, Pranay Prakash, and Karthik Kalyanaraman on the cookbook branch.

In saga.mdx, remove the unnecessary `if (!(error instanceof FatalError)) throw error;` guard in the catch block — compensations should always unwind regardless of error type. Replace the `while/pop()!()` loop with a cleaner `for...of reverse()` to avoid the non-null assertion.

In ai-sdk.mdx, split the "Using Different Providers" section into two subsections: "Vercel Gateway (string model IDs)" clarifying that all string model IDs route through Gateway, and "Direct Provider Access" showing how to import from provider packages like `@workflow/ai/openai` to bypass Gateway. Change the "Tool Functions as Steps" section to "Tool Functions with Steps" and reword to explain that tool execute functions can optionally include steps via "use step" but don't have to — when they aren't steps, they run in workflow context and can modify workflow state directly.

In sandbox.mdx, rewrite the page to reflect that `@vercel/sandbox` now has first-class Workflow SDK support. Replace all `declare function` stubs and `// TODO` placeholders with real `import { Sandbox } from "@vercel/sandbox"`. Remove the four separate "use step" wrapper functions (provisionSandbox, runCommand, teardownSandbox, saveSandboxSnapshot) and show direct `Sandbox.create()`, `sandbox.runCommand()`, and `sandbox.destroy()` calls in the workflow function since these implicitly run as steps. Simplify the agent tool example to use inline execute functions that call Sandbox methods directly with an `activeSandbox` variable for workflow state.

Across all cookbook files, replace "Workflow DevKit" with "Workflow SDK" (8 instances in 5 files: publishing-libraries.mdx, secure-credentials.mdx, ai-sdk.mdx, chat-sdk.mdx, sandbox.mdx).

* docs: simplify cookbook index to plain MDX listing

Replace the interactive CookbookExplorer (726-line decision tree + browse
component) with a simple MDX page that lists recipes grouped by category
with linked titles and descriptions. Remove v1-v5 design variations and
trim cookbook-tree.ts to sidebar-only metadata.

* fix type checks

Nathan Rajlich ec517fa225 Add features.encryption to WorkflowMetadata (#1652)
* Add features.encryption to WorkflowMetadata

Expose a `features` object on `getWorkflowMetadata()` so library
authors can detect at runtime whether encryption is enabled for the
current workflow run, allowing them to conditionally handle sensitive
data serialization.

* Improve docs example: show workflow-level encryption check

Step inputs are serialized before the step body runs, so the encryption
check should happen in the workflow function before passing data to
steps.

* Fix docs example: show encryption check on step return value

Step return values are serialized to the event log after the step body
runs, so this is where the check is actually useful - controlling what
data gets persisted as output.

1. Remove the "Machine-Readable Surfaces" section from docs/content/docs/observability/index.mdx (reviewers say it's unnecessary and already in world docs)
2. Remove all @skip-typecheck annotations from durable-agent.mdx (8) and server-based.mdx (1) — types exist in built packages/ai/dist after pnpm build
3. In durable-agent.mdx, change "machine-readable tool activity" to "tool call details" in the stream() return description
4. In durable-agent.mdx "Aborting Long-Running Streams" section, add a warning callout that abortSignal is not yet supported (blocked by #1301), recommend timeout instead
5. In event-sourcing.mdx, update requestId description: "On Vercel, requestId is the platform request ID when available. Other worlds are not expected to provide a requestId."
6. In get-world.mdx, change "user-friendly names from the machine-readable workflowName field" to "human-readable names from the workflowName field"
