* Handle 409 conflict when completing waits that were already completed
When multiple concurrent workflow invocations race to complete the same
wait, the server returns 409 (conflict) for duplicates. This change
handles the 409 gracefully in both runtime.ts (sleep elapsed check) and
runs.ts (wakeUpRun), preventing crashes and treating already-completed
waits as successful.
Also updates event-sourcing docs to reflect that waits are now
materialized as entities in storage with atomic completion guarantees.

* Materialize waits as entities in local and postgres worlds to prevent duplicate wait_completed events
Adds Wait type/schema to the shared world package and implements wait entity
materialization in both local (filesystem) and postgres world implementations,
matching the DynamoDB behavior. wait_created creates a wait entity with status
'waiting', and wait_completed transitions it to 'completed' with guards that
reject duplicates (409).

## Summary
- Generates `runId` client-side in `start()` using ULID (`wrun_${ulid()}`), instead of deferring to the server
- Passes client-generated `runId` to `events.create()` and verifies the server accepted it
- Simplifies `runId` types from `string | Promise<string>` to `string` throughout the serialization layer
- Removes the `withResolvers<string>()` / deferred runId pattern that was needed when `runId` was server-generated
- Updates `Streamer` interface and `WorkflowServerWritableStream` to use plain `string` runId
- Updates `Storage.events.create()` first overload to accept `string | null` instead of just `null`
This is a prerequisite for E2E encryption, where we need the `runId` before serialization so it can be used as part of the encryption context.
## Test plan
All existing tests pass. Updated `start.test.ts` to expect client-generated runId, removed `writable-stream.test.ts` promise runId test (no longer applicable).
* Parallelize async operations in step handler for performance
- Parallelize getPort(), getSpanKind(), and world.steps.get() calls
- Start step_started event creation while hydrating arguments (CPU work)
- Parallelize step_completed event with trace serialization
Co-Authored-By: Claude Opus 4.5 <noreply@anthropic.com>
* Fix race condition: await step_started before hydration
Reverts Optimization 1 to fix a race condition where hydrateStepArguments()
could throw before stepStartedPromise was awaited, causing stale step.attempt
in the catch handler and potentially allowing extra retries.
Optimizations 0 and 2 are preserved as they don't have this issue.

* Skip initial world.steps.get() in step handler for performance
Eliminate the world.steps.get() HTTP call by calling step_started first
and relying on server-side validation. This saves 50-80ms per step
execution by removing one HTTP round-trip.
The server (workflow-server) now validates:
- Step not in terminal state (returns 409)
- retryAfter timestamp reached (returns 425 with Retry-After header)
- Workflow still active (returns 410 if completed)
Changes:
- Remove world.steps.get() from initial Promise.all
- Call step_started first to get step entity and validate state
- Handle 409 (terminal state) by re-queueing workflow
- Handle 425 (retryAfter not reached) by returning timeout
- Handle 410 (workflow gone) as no-op
Co-Authored-By: Claude Opus 4.5 <noreply@anthropic.com>
* Add retryAfter validation to local and postgres worlds
Add server-side retryAfter validation to match workflow-server behavior:
- Check retryAfter timestamp before allowing step_started
- Return HTTP 425 with retryAfter timestamp in response meta
- Clear retryAfter field when step starts successfully
This ensures consistent behavior across all world implementations
and allows the step-handler optimization to work correctly.

* Fix step terminal state HTTP status code to 409 (Conflict)
Aligns local and postgres worlds with workflow-server, which returns
409 via InvalidOperationStateError for step in terminal state.

* Fix world-vercel telemetry to use parent application's tracer
The world-vercel package was creating spans under a separate
'workflow-world-vercel' service name, causing HTTP spans for
workflow-server API calls (step_started, step_completed) to be
filtered out when viewing traces for the main application service.
Now uses the same 'workflow' tracer name as @workflow/core to
ensure all spans are reported under the parent application's service.
* Update /demo command to include OTEL tracing with Jaeger
- Start Jaeger container for local trace visualization
- Configure OTEL exporter environment variables for dev server
- Open Jaeger UI automatically
- Add documentation about available trace attributes
Co-Authored-By: Claude Opus 4.5 <noreply@anthropic.com>
* Add OTEL instrumentation to world-local and improve trace consistency
- Add telemetry.ts and instrumentObject.ts to world-local for tracing parity
with world-vercel (world.runs, world.steps, world.events, world.hooks spans)
- Change workflow span name from uppercase "WORKFLOW" to lowercase "workflow"
for consistency with step spans and OTEL naming conventions
- Add step.execute child span to trace actual user step function execution
separately from step handler infrastructure
These changes enable local development to have the same observability as
production deployments, making performance analysis and debugging easier.
Co-Authored-By: Claude Opus 4.5 <noreply@anthropic.com>
* Use uppercase WORKFLOW and STEP span names for consistency with HTTP spans
HTTP spans use uppercase methods like "GET /path" and "POST /path".
Following the same convention, workflow and step spans now use:
- WORKFLOW <workflow-name>
- STEP <step-name>
Child spans (workflow.run, workflow.loadEvents, step.execute, world.events.create)
remain lowercase as they represent internal operations, not top-level entries.

* Add W3C trace context headers to step queue messages
Include traceparent and tracestate headers when queueing step
execution messages. This enables automatic trace propagation
by Vercel's infrastructure, potentially linking step invocation
spans to the parent workflow trace.
The trace carrier is now serialized once and included in both:
- Payload: for manual context restoration in step handler
- Headers: for automatic HTTP-based trace propagation

* Improve OTEL tracing with service attribution and enhanced instrumentation
- Add peer.service attributes for workflow-server and VQS for Datadog service maps

- Include event type in world.events.create span names (e.g., "world.events.create step_started")
- Add span.recordException() for errors with category classification (fatal/retryable/transient)
- Add span events for milestones: retry.scheduled, step.skipped, step.delayed
- Add HTTP semantic conventions with peer.service for world-vercel HTTP calls
- Add baggage propagation for workflow context (run_id, workflow_name)

* Use span name for rpc.method to show event type in Datadog resource
Datadog derives the resource name from rpc.method attribute. Updated to
use the full span name (which includes event type) instead of just the
method name, so Datadog shows "world.events.create step_started" instead
of "world.events.create workflow-server".

* Use lazy ref resolution for events where client discards response data
Skip expensive S3 ref resolution (~200-460ms) for event types where

for run_created, run_started, and step_started where the client
reads the response.

* hotfix for error propogation

* Fix: The code attempts to pass an unsupported `fatal` property when creating a `step_failed` event. The TypeScript schema for `step_failed` events only allows `error` and `stack` properties, so the `fatal` property causes a compilation error.
This commit fixes the issue reported at packages/core/src/runtime/step-handler.ts:133-139
## TypeScript error: Invalid property 'fatal' in step_failed event
**What fails:** TypeScript compilation fails in `packages/core` due to an invalid property in the `step_failed` event creation.
**How to reproduce:**
```bash
cd /vercel/sandbox/primary
pnpm run -F @workflow/core build
```
**Result:**
```
src/runtime/step-handler.ts(133,32): error TS2769: No overload matches this call.
Overload 1 of 2, '(runId: null, data: { eventType: "run_created"; ... }, gave the following error.
Argument of type 'string' is not assignable to parameter of type 'null'.
Overload 2 of 2, '(runId: string, data: CreateEventRequest, params?: CreateEventParams | undefined): Promise<EventResult>', gave the following error.
Object literal may only specify known properties, and 'fatal' does not exist in type '{ error: any; stack?: string | undefined; }'.
```
**Issue:** The code attempted to pass a `fatal: true` property in the `eventData` object when creating a `step_failed` event. However, the event schema defined in `packages/world/src/events.ts` for `StepFailedEventSchema` only allows `error` and `stack` properties - the `fatal` property is not part of the schema.

* Fix: Code silently skips updating workflowRun if result.run is undefined, causing workflows to be incorrectly skipped instead of throwing an error
* Add hook_conflict event type for duplicate token detection
Implements hook_conflict events across all world implementations to handle
cases where a workflow attempts to use a hook token already claimed by another
workflow. Instead of throwing errors, the system now records hook_conflict
events in the event log, enabling deterministic replay.
- Add HookConflictEvent schema to @workflow/world
- Implement hook_conflict in world-local, world-postgres, and suspension-handler
- Update hook consumer to reject promises with WorkflowRuntimeError on conflict
- Add HOOK_CONFLICT error slug with documentation
- Add e2e and unit tests for conflict scenarios

* Add backwards compatibility for event-sourced runs
- Add RunNotSupportedError for runs requiring newer world versions
- Add semver-based version utilities (isLegacyVersion) to @workflow/world
- World implementations check specVersion and route to legacy handlers
- Legacy runs (< 4.1.0): run_cancelled skips event storage, wait_completed stores event only
- New runs always get current world version (4.1.0-beta.0)
- Make EventResult.event optional for legacy compatibility

* Add legacy/backwards compatibility tests
Tests for world-local and world-postgres covering:
- Legacy runs (specVersion < 2 or null/undefined)
- run_cancelled handling (updates run, no event stored)
- wait_completed handling (stores event only)
- Rejection of unsupported events
- Hook cleanup on cancellation

* Wire specVersion from client through world backends
- Core runtime now sends specVersion in run_created eventData
- world-local accepts specVersion from eventData (defaults to current)
- world-postgres accepts specVersion from eventData (defaults to current)
This matches workflow-server behavior where v2 endpoints accept
specVersion from the client, while v1 endpoints default to legacy.

* Move specVersion to event object level, propagate to entities
- Add specVersion to BaseEventSchema (event level, not eventData)
- Remove specVersion from RunCreatedEventSchema.eventData
- Core runtime sends specVersion on event object
- world-local reads specVersion from event, propagates to run/step/hook entities
- world-postgres reads specVersion from event, propagates to run/step/hook entities
This ensures specVersion flows from client through event to all created entities.

* Update specVersion to be optional in types for backwards compatibility
- specVersion is optional in all entity schemas (runs, steps, hooks, events)
for backwards compatibility with legacy data in storage
- Runtime always sends specVersion on event requests
- world-local and world-postgres provide fallback to SPEC_VERSION_CURRENT
- Test helpers include specVersion in all event creation calls
- EventWithRefsSchema in world-vercel defaults specVersion to 1 for legacy

* Add specVersion to all event creation calls in core package
The server's CreateEventSchemaV2 requires specVersion on all events,
but only run_created was sending it. This caused 400 Bad Request errors
for all other event types (run_started, run_completed, run_failed,
run_cancelled, step_created, step_started, step_completed, step_failed,
step_retrying, hook_created, hook_received, wait_created, wait_completed).
Now all event creation calls include specVersion: SPEC_VERSION_CURRENT.
