* Fix Biome lint violations and add Biome CI check
Biome was not configured to respect .gitignore, so ~92% of the 13,355
reported diagnostics came from gitignored build artifacts. Enable VCS
integration (useIgnoreFile), apply safe auto-fixes across the repo, fix
the remaining mechanical errors by hand, downgrade judgment-call a11y /
dangerouslySetInnerHTML rules to warnings, and add a 'biome ci' job to
the Lint workflow so violations block PRs going forward.
* Use an empty changeset (no behavior change, no release needed)
* build: declare typescript (catalog:) in every package that runs tsc
Twenty packages invoke tsc in their build/typecheck scripts without
declaring a typescript dependency, resolving whatever tsc pnpm happens
to leave reachable. That broke locally after the TypeScript 6 upgrade
(#2700): base.json now uses the TS6-only 'types': ['*'] wildcard, and
worktrees carrying pre-upgrade node_modules/.bin/tsc shims (orphaned
typescript@5.9.3 bins that pnpm never refreshes for an undeclared
dependency) fail with TS2688 'Cannot find type definition file for *'.
Declaring 'typescript': 'catalog:' (the convention nest already
follows) makes pnpm own each package's tsc bin, so version upgrades
refresh the shims and this staleness class cannot recur. Packages
without tsc in their scripts are left unchanged.
Full pnpm build: 27/27 tasks green.
* Address review: drop duplicate zod devDep; regenerate lockfile minimally
- packages/world listed zod in both dependencies and devDependencies
(pre-existing on main, surfaced by the devDependencies sort) — keep
the runtime dependency only.
- Regenerate pnpm-lock.yaml from a pristine main baseline with
--lockfile-only (a clean-main run produces zero diff, so main has no
drift). Remaining non-typescript changes are mechanical consequences
of the change itself: typescript is an (optional) peer of several
tooling dependencies, so declaring it in 20 importers creates new
peer-resolution snapshot variants and prunes the now-orphaned old
ones; plus one radix-ui 1.6.1->1.6.2 refresh in docs caused by its
floating 'latest' specifier.
- Validated: pnpm install --frozen-lockfile succeeds; full build 27/27.
* 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`

* 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.

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

* 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.

* [docs] Rename useworkflow.dev to workflow-sdk.dev
* [chore] Add changeset for domain rename
* [docs] Revert sitemap rewrite to useworkflow.dev (crawled-sitemap not yet available for new domain)
The previous pre-release versions (4.x.y-beta.N) caused two issues:
- semver.inc('4.0.0-beta.N', 'major') returns 4.0.0, not 5.0.0
- Pre-release numbers carried over (beta.61 -> beta.62 instead of beta.0)
Setting all versions to 4.0.0 (non-pre-release) ensures a clean major
bump to 5.0.0-beta.0. Also removes @workflow/swc-playground-wasm from
the changeset and pre.json since it is a private package.

Apply messages override before system override so that the system
message is prepended to the new prompt instead of being discarded.
Previously, system was applied first then messages replaced the
entire conversation prompt, losing the system message.
Add tests for prepareStep system/messages ordering:
- system only: prepended to prompt
- system + messages: system prepended to replaced messages
- system + messages with existing system: replaces existing
- system updates across multi-step tool call rounds
* Add DurableAgent compat tests, e2e agent tests, and migrate to AI SDK v6
- Port ToolLoopAgent test suite as DurableAgent compatibility spec (34 tests,
all expected to fail — each maps to a feature gap to implement)
- Add e2e workflow definitions using mock LLM providers (no API keys needed)
- Add e2e test file for DurableAgent workflows
- Migrate all AI SDK types from V2 to V3 (LanguageModelV2 → V3, etc.)
- Drop AI SDK v5 support: ai peer dep ^5||^6 → ^6, @ai-sdk/provider ^2||^3 → ^3
- Update ai catalog version from 5.0.104 to 6.0.116
- Simplify CompatibleLanguageModel to just LanguageModelV3

* Implement Tier 1+2 gaps, add @workflow/ai/test mock provider, wire e2e in CI
DurableAgent API additions:
- Add `instructions` (string | SystemModelMessage | SystemModelMessage[])
as alias for deprecated `system` on constructor
- Add `onStepFinish` and `onFinish` on constructor, merged with stream
options (constructor first, then stream — matching ToolLoopAgent)
- Add `timeout` on stream options (converted to AbortSignal)
- Add `text`, `finishReason`, `totalUsage` to onFinish event
Test infrastructure:
- Add @workflow/ai/test export with `mockModel()` wrapper that wraps
MockLanguageModelV3 from ai/test as an async step function
- E2e workflows now use mockModel() + convertArrayToReadableStream
from @workflow/ai/test instead of inline V2 mock models
- Add e2e-agent.test.ts to test:e2e script so it runs in CI
- Flip 6 compat tests from it.fails → it (now passing)

* Remove e2e agent tests — mock models can't serialize across step boundary
The workflow runtime serializes step arguments, and function closures
(like mock model doStream callbacks) aren't serializable. Mock models
only work in unit tests where 'use step' is a no-op. Real e2e agent
tests would need either a mock HTTP server or real provider credentials.
Also removes 'use step' from mockModel wrapper (closures aren't
serializable) and reverts test:e2e script and example workbench dep.

* Add working e2e agent tests with mock model step factories
Mock model factories use the same 'use step' pattern as real providers
(anthropic, openai). Closure variables are bound to locals at the step
body level so the SWC plugin detects them via __private_getClosureVars.
All 4 e2e tests pass against local dev server:
- agentBasicE2e: text response (11s)
- agentToolCallE2e: single tool call + text (11s)
- agentMultiStepE2e: 3 sequential tool calls (12s)
- agentErrorToolE2e: FatalError recovery (11s)
Also adds e2e-agent.test.ts to test:e2e script for CI.

* Use @workflow/ai/test package imports for e2e mock models
Split mock provider into two files to work around SWC constructor
closure bug: mock-create.ts has the model creation logic,
mock.ts has the 'use step' wrappers that capture only serializable
args (strings, plain object arrays).
Exports mockTextModel(text) and mockSequenceModel(responses) —
same 'use step' pattern as real providers (anthropic, openai, etc.).
E2e workflows now import directly from @workflow/ai/test.

* Simplify mock provider, add comprehensive e2e tests for all features + gaps
Mock provider:
- Replace mock-create.ts with mock-function-wrapper.ts that simply wraps
MockLanguageModelV3 constructor in a function (SWC class closure bug)
- mockTextModel/mockSequenceModel use mockProvider() from wrapper file
- Bind closure vars at step body level (_text = text) for SWC detection
- Fix AbortController not available in workflow VM sandbox
E2e tests (13 total, all passing):
- Core: basic text, tool call, multi-step, error recovery (4)
- Callbacks: onStepFinish constructor+stream, onFinish constructor+stream (2)
- Features: instructions, timeout (2)

- needsApproval as function should receive tool input
E2e tests: 1 new test for tool approval gap
- Documents that needsApproval is currently ignored (tool executes anyway)

* Fix: Documentation for `PrepareStepInfo` and `PrepareStepResult` interfaces references the obsolete `LanguageModelV2` type while the codebase has fully migrated to `LanguageModelV3`.
This commit fixes the issue reported at docs/content/docs/ai/message-queueing.mdx:36
**Bug explanation:**
The codebase migrated from AI SDK V2 to V3. In `packages/ai/src/agent/types.ts`, `CompatibleLanguageModel` is defined as `LanguageModelV3` (from `@ai-sdk/provider`). The actual TypeScript interfaces in `packages/ai/src/agent/durable-agent.ts` use `string | (() => Promise<CompatibleLanguageModel>)` which resolves to `LanguageModelV3`.
However, the documentation in `docs/content/docs/ai/message-queueing.mdx` at lines 36 and 43 still referenced `LanguageModelV2` for the `model` field in both `PrepareStepInfo` and `PrepareStepResult`. This is inconsistent because:
1. The `messages` fields in the same interfaces were correctly updated to `LanguageModelV3Prompt`
2. The actual source code uses `LanguageModelV3` via `CompatibleLanguageModel`
3. There is no `LanguageModelV2` type anywhere in the codebase
This would mislead developers reading the documentation into using the wrong type.
**Fix explanation:**
Changed both `LanguageModelV2` references to `LanguageModelV3` on lines 36 and 43 of the documentation file, matching the actual codebase types. Verified no other stale `LanguageModelV2` references remain in the docs directory.

'@types/node') weren't matched, causing "unresolved catalog dependencies"
errors in CI.

* Fix CI build failures, add changeset
- Remove streamdown plugins from reasoning.tsx (same CI type mismatch)
- Cast ToolHeader type prop and WorkflowChatTransport to fix type errors
- Fix pnpm-workspace.yaml single→double quotes for staging script
- Add minor changeset for @workflow/ai (breaking: AI SDK v6 migration)

* Sync webpack workbench with turbopack: add chat UI deps and symlinks
- Symlink app-shell.tsx, chat-client.tsx, agent_chat workflow,
chat API routes into nextjs-webpack
- Add matching deps: streamdown, @streamdown/*, shiki, cmdk, nanoid,
motion, @radix-ui/react-use-controllable-state

* Fix circular symlink: restore chat-client.tsx as real file in turbopack
The previous commit accidentally converted turbopack's chat-client.tsx
into a circular symlink pointing to itself. Webpack's symlink to it
then couldn't resolve, breaking both builds on Vercel.

* Add missing deps to webpack: use-stick-to-bottom, radix-ui, @vercel/blob

* Fix model picker: merge body params via prepareSendMessagesRequest
WorkflowChatTransport sends { messages } by default, ignoring the
body option from ChatRequestOptions. Use prepareSendMessagesRequest
to merge { messages, ...body } so the model selection reaches the API.

* Fix WorkflowChatTransport: forward body/headers from ChatRequestOptions
The transport hardcoded body: undefined when calling
prepareSendMessagesRequest, so extra body params (like model selection)
from sendMessage({ body: { model } }) were silently dropped.
Now forwards options.body and options.headers to both
prepareSendMessagesRequest and the default request body.

* Fix model IDs: use real AI Gateway model names
gpt-5.2 and gpt-5.3 don't exist in the AI Gateway.
Replace with gpt-4o and gpt-4o-mini.
Co-Authored-By: Claude Opus 4.6 (1M context) <noreply@anthropic.com>
* Use correct AI Gateway model IDs: Opus 4.5, GPT-5.2, GPT-5.3

* Enable reasoning for all model providers
- Anthropic: thinking.type='enabled' with 10k token budget
- OpenAI: reasoningEffort='high'
- Instructions kept for all models (no longer conditionally removed)
Co-Authored-By: Claude Opus 4.6 (1M context) <noreply@anthropic.com>
* Fix OpenAI reasoning: use 'medium' effort (GPT-5.3 doesn't support 'high')
Co-Authored-By: Claude Opus 4.6 (1M context) <noreply@anthropic.com>
* Address all PR review comments
- Change changeset from minor to patch (repo convention)
- Use ?? instead of || for system/instructions fallback
- Clean up timeout: store ID, clearTimeout in finally, { once: true } listeners
- Update class docstring example to use instructions
- Map unrecognized finish reasons to 'other' with validation
- Fix duplicate test, align assertion for unrecognized type
- Support ^ exponentiation in calculate tool
- Remove debug console.log from chat client
- Fix ReactNode/ComponentProps type imports in UI components
- Remove unused MockLanguageModelV3 re-exports from mock.ts

* Remove accidentally created empty mock2.ts
Co-Authored-By: Claude Opus 4.6 (1M context) <noreply@anthropic.com>
* Change changeset back to minor for breaking AI SDK v6 migration

* Fix agent e2e tests: add Vercel world setup for CI
The agent e2e tests only configured the local filesystem world but not
the Vercel world backend. On CI (Vercel prod tests), this caused
VercelOidcTokenError because the world wasn't initialized.
Now matches the setup pattern from e2e.test.ts: configures Vercel world
with OIDC token and project config from CI environment variables.

* Deduplicate e2e test utilities: extract shared code to utils.ts
Extract manifest fetching, workflow lookup, world setup, and types
into shared utils.ts. Both e2e.test.ts and e2e-agent.test.ts now
import from the same source, eliminating ~200 lines of duplication.
Shared utilities:
- WorkflowManifest interface
- fetchManifest() with caching
- getWorkflowMetadata() with retry and fallback
- setupWorld() handling local/Vercel/Postgres backends

* Fix missing deploymentUrl args in e2e.test.ts after utils refactor
Co-Authored-By: Claude Opus 4.6 (1M context) <noreply@anthropic.com>
* Add @workflow/ai dep to all workbenches for agent e2e tests
All workbenches now have @workflow/ai as a dependency and the
100_durable_agent_e2e.ts symlink, so agent e2e tests run everywhere.

* Fix missing imports in e2e.test.ts: add fetchManifest and sleep
The utils refactor removed these imports but they're still used:
- fetchManifest: used in stepFunctionAsStartArgWorkflow test
- sleep (setTimeout): used in webhookWorkflow test
