* cli: show run region in inspect output via World.regionForRunId
Adds an optional reverse-lookup hook to the World interface —
regionForRunId(runId): string | null — so tooling can display a run's
region generically. Worlds without a regional dimension simply omit
the hook and no region output appears.
- @workflow/world: new optional interface member (documented: must not
throw; null = undeterminable)
- @workflow/world-vercel: implements it from the run-ID region tag
(tagged -> embedded region, untagged legacy -> default region,
malformed -> null)
- @workflow/cli: 'workflow inspect runs' gains a region column
(between workflowName and status) and 'workflow inspect run <id>'
a region property, in both table and JSON output — only when the
world defines the hook
* Generalize the inspect hook: World.describeRun display fields
Replaces regionForRunId on the World interface with describeRun, per
review: worlds may want to expose more than a region, and the
information need not be encoded in the run ID — describeRun receives
the run entity itself (loosely typed, mirroring createRunId), so a
world can derive fields from executionContext or any other property.
Each returned key becomes an inspect column/property; null values are
preserved in structured output ('applicable but undeterminable' vs.
the hook being absent entirely).
- world-vercel: describeRun returns { region } decoded from the run
ID tag (regionForRunId stays exported as a utility); entities
without a usable runId contribute nothing
- CLI listing: columns come from the union of keys the world returns
for the page, inserted before status; both analytics and storage
paths; detached call site binds this
- CLI showRun: merges the world fields into detail/JSON output via a
method-style call (preserves this), keeping nulls
- tests: field merging (multi-key), null preservation in JSON, hook
absent, and world-vercel describeRun coverage incl. no-runId
entities
* cli: evaluate describeRun defensively
Per review: the World interface says describeRun is pure and must not
throw, but it is an external extension point and the CLI should not
trust that. New safeWorldFields helper, used by both the listing and
showRun paths:
- a throwing implementation contributes no fields instead of crashing
the inspect command
- keys that already exist on the run row are dropped, so a world can
never overwrite canonical fields (status, runId, ...) in output
Tests: canonical fields survive a clobbering describeRun (extra keys
still merged); a throwing describeRun leaves rows untouched and the
command succeeds.
* Allow async describeRun implementations
Per review: widening a sync signature to async later would break every
consumer, while accepting sync-or-async from day one is free — sync
implementations (like world-vercel's) remain valid, and consumers
simply await, which handles both. The performance intent lives on as
documented guidance: the hook is called once per displayed run, so
implementations should stay cheap and avoid I/O; the CLI evaluates a
page's rows concurrently so an async world costs one await per page,
not per row. Promise rejections get the same treatment as throws:
no fields, never a crash.

* 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.
* web: infinite scroll for the runs table
Replace Previous/Next cursor paging with front-style infinite scroll:
a useInfiniteList hook accumulates cursor pages with per-run dedup and
generation-guarded resets, and useLoadMoreOnScroll drives loadMore from
an IntersectionObserver sentinel (400px prefetch margin, guarded against
double-fetch, observed against the table's scroll container). Footer now
shows the loaded count and the analytics lookback window.

* web: back the runs infinite list with SWR so tab switches serve from cache
Rewrite useInfiniteList on useSWRInfinite: pages are keyed by
[cacheKey, cursor] in SWR's global cache, so unmount/remount (switching
tabs) restores fetched pages instantly instead of refetching. Revalidation
is conservative because analytics list queries are expensive:
revalidateFirstPage and revalidateIfStale are off; freshness comes from
the Refresh button and the visibility-change auto-reload, which map to
reload() (reset to first page + revalidate).

* world: expose startTime/endTime on analytics runs listing
The workflow-server /v2/analytics/runs endpoint has accepted a bounded
startTime/endTime window since it shipped, and is significantly faster
with one (the window prunes the ClickHouse scan: ~2s for 12h vs ~8s for
the default 30-day entitlement window). The world client never exposed
the params, so the CLI and web UI could only issue windowless requests.
Pass them through so clients can send bounded windows (e.g. a period
picker like front's workflows o11y).
Co-Authored-By: Claude Fable 5 <noreply@anthropic.com>
* web: front-style period picker for the runs list
Add a time-window picker (1h/6h/24h/3d/7d/30d, default 24h, URL-backed
via ?period=) that sends an explicit startTime/endTime window through
fetchRuns -> world.analytics.runs.list, keeping the ClickHouse scan
bounded. The window is frozen per selection/refresh so all cursor pages
share the same bounds, and it participates in the SWR cache key.
Plan tiers are honored data-driven from the server's pageInfo: presets
longer than the plan's observability lookback are disabled in the picker
(labeled Observability Plus when an upgrade is available), and a 402
observability-upgrade-required response renders through the existing
upgrade-required error handling. The footer now labels the selected
window instead of the plan lookback. The runtime (local) fallback path
ignores the window since the storage API has no time filter.

* web: allow status filtering without a workflow name filter
The status dropdown was disabled on Vercel backends until a workflow was
selected — a limitation of the runtime DynamoDB API's index design. The
runs list now reads via world.analytics, whose ClickHouse query filters
derived status independently of workflowName, so drop the guard.
Co-Authored-By: Claude Fable 5 <noreply@anthropic.com>
* cli: time-window flags for runs listing; widen name lookups past the default window
The analytics backend now defaults windowless runs listings to the
trailing 24h. Replicate the web's window support in the CLI:
- 'workflow inspect runs' gains --since/--until (relative durations like
30m/12h/7d/2w, or timestamps) which are sent as an explicit
startTime/endTime window. Out-of-plan windows surface through the
existing observability-upgrade-required handling; non-analytics
backends warn that the flags are ignored.
- 'workflow start <name>' resolves the workflow's latest run via a
windowless (default-window) listing and now retries across the plan's
whole observability window on a miss, so names idle for more than a
day keep resolving.
- Bulk 'workflow cancel' matches across the plan window up front — a run
can sleep or wait on a hook for days without recent events, so the
default recent window must not bound cancellation matching.

* chore: tighten changeset descriptions
Co-Authored-By: Claude Fable 5 <noreply@anthropic.com>
* web: persist frozen listing windows across remounts; minimize lockfile diff
Address review findings:
- The frozen startTime/endTime lived in component state, but RunsTable
fully remounts on tab switches, so every remount minted a new SWR cache
key — the cached-pages restore never hit and cache entries grew
unboundedly (one per key, including every 5s local-backend poll tick).
Move the frozen windows to a module-scope store keyed by period: a
remount reuses the stored window (same cache key, instant restore), and
the window only advances on explicit refresh/reload. Non-analytics
backends now send no window at all (the runtime APIs ignore it anyway),
which also hides the period picker and window label there.
- Regenerate pnpm-lock.yaml from main so the diff contains only the swr
addition (plus its own use-sync-external-store dependency), dropping
the unrelated docs-importer radix-ui re-resolutions.

* cli: restore dynamic world loading for community backends
Since #2752 moved world selection to static injection, setupCliWorld only
constructed the vercel, local, and postgres worlds explicitly and threw
'Unsupported workflow backend' for anything else — breaking community
worlds (e.g. @workflow-worlds/turso) that previously loaded through the
dynamic createWorld() in @workflow/core/runtime.
Generalize the postgres-only dynamic path: any backend other than
vercel/local is now resolved from the user's project directory and loaded
via its createWorld() export, matching @workflow/web's world construction
(#2804), with clear errors when the package is missing or does not export
createWorld().

* Add workflow analytics world APIs
* cli: read list views from world.analytics when available
inspect list views (runs, steps, events, hooks, sleeps) now read from the
optional world.analytics namespace when the active backend provides one,
falling back to the runtime storage APIs otherwise. Payload and detail views
are unchanged. Deprecate --with-data for list views; payloads are viewable
per-resource via 'inspect <resource> <id>'.
* cli: keep hook listing on the runtime storage API
The analytics read path omits ownerId (and the secret hook token), so routing
hook listing through it silently drops the ownerId column. Keep inspect hooks
on the runtime APIs, consistent with the web observability UI. Runs, steps,
events, and sleeps continue to use the analytics read path when available.

* 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.
* refactor(swc-plugin): remove client transform mode, merge into step mode
Remove the `client` transform mode from the SWC compiler plugin. The
`client` and `step` modes were nearly identical — both preserved step
function bodies, replaced workflow bodies with throw stubs, and emitted
the same JSON manifest. Step mode now absorbs all client-mode behaviors:
- Dead code elimination (previously only workflow + client)
- Hoisted variable references for object property steps
- All integrations use mode: 'step' instead of 'client'
BREAKING CHANGE: The `client` value for the SWC plugin `mode` option is
no longer accepted. Use `step` instead.
* fix(nitro): force-inline workflow packages in dev mode for serde classId registration
In dev mode, Nitro's Rollup externalizes npm packages like @workflow/core,
so the SWC transform plugin never processes files like run.js. This means
serde classes (e.g. Run) never get the classId registration IIFE, causing
serialization failures when step functions return Run instances.
Uses a Rollup resolveId hook to force workflow SDK packages to be bundled
(non-external) while leaving all other dependencies external. This is more
targeted than noExternals=true which bundles everything and causes TDZ
errors from circular imports in packages like vue-bundle-renderer/h3.
The Nitro module now also ignores .nitro/workflow/** in watchOptions so
writing generated workflow bundles does not retrigger Nitro's own dev
bundle rebuild loop.
Also wraps dev:reload workflow rebuilds and makes LocalBuilder.build()
atomic (writes to temp files, renames on success) to avoid partial output
state during HMR.
For Nuxt, also configures Vite's ssr.noExternal to bundle workflow
packages in the SSR context.
* fix(nitro,nuxt): address review feedback on dev-mode classId fix
- nitro builders: use crypto.randomUUID() for temp file suffix instead of
Date.now() to avoid collisions under rapid/concurrent build() calls,
and serialize concurrent build() calls through an internal queue so
two overlapping dev rebuilds cannot clobber each other's temp outputs.
- nitro index: use fileURLToPath() to convert file:// URLs to filesystem
paths, which correctly handles Windows paths (file:///C:/... -> C:\...)
and percent-decoding, instead of relying on new URL(...).pathname.
- nuxt module: normalize vite.ssr.noExternal to an array (preserving any
existing string/RegExp/array entry) before appending workflow package
matchers, so the force-bundle behavior is not a no-op when noExternal
is already set to a non-array value.
