* 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.
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.
* feat: export semantic error types and add API reference documentation
Add missing error exports (HookNotFoundError, EntityConflictError,
RunExpiredError, TooEarlyError, ThrottleError, RunNotSupportedError,
WorkflowWorldError) to workflow/internal/errors. Create new error
classes for world-level semantics. Tighten TSDoc comments on all
error classes. Add API reference docs for all error types.

* fix: use @setup declarations, workflow/errors import, and errors/ doc section
- Replace @skip-typecheck with proper `declare` + `// @setup` lines
so code samples are typechecked but setup lines hidden from readers
- Add `workflow/errors` export to package.json (public API, replaces
`workflow/internal/errors` in docs)
- Add `workflow/errors` path mapping in docs-typecheck type-checker
- Add HookConflictError to re-export list
- Move all error docs under api-reference/workflow/errors/ subdirectory
- Update all internal cross-references and links

* refactor: move error docs to top-level workflow-errors section
- Move semantic error docs to api-reference/workflow-errors/ (matching
the workflow/errors import path, like workflow-api for workflow/api)
- Keep FatalError and RetryableError in api-reference/workflow/ since
they're imported from workflow, not workflow/errors
- Fix all cross-reference links

* chore: update HTTP debug logger JSDoc to clarify scope
Co-Authored-By: Claude Opus 4.6 (1M context) <noreply@anthropic.com>
* fix: make TooEarlyError.retryAfter a number (seconds) matching WorkflowWorldError
TooEarlyError.retryAfter is now seconds (number) instead of a Date,
consistent with ThrottleError and WorkflowWorldError. The conversion
from seconds to Date is done at the consumer site (step-handler) rather
than at construction time.

* fix: address review feedback on docs accuracy
- WorkflowWorldError docs: add status, code, url, retryAfter properties
to TSDoc; clarify that .is() only matches direct instances (not
subclasses); use instanceof in catch-all example
- TooEarlyError/ThrottleError docs: mark retryAfter as optional (?)
to match actual type definitions

Added support for custom class instance serialization across workflow/step boundaries.
### What changed?
- Introduced a new `@workflow/serde` package with `WORKFLOW_SERIALIZE` and `WORKFLOW_DESERIALIZE` symbols
- Enhanced the serialization system to handle custom class instances using these symbols
- Updated the SWC plugin to detect classes with serialization methods and register them
- Added class registry mechanism that works in both step and workflow contexts
- Implemented comprehensive tests for various serialization scenarios
### How to test?
The PR includes a new e2e test `customSerializationWorkflow` that demonstrates the feature:
```typescript
import { WORKFLOW_SERIALIZE, WORKFLOW_DESERIALIZE } from '@workflow/serde';
// Define a class with custom serialization
class Point {
constructor(public x: number, public y: number) {}
static [WORKFLOW_SERIALIZE](instance: Point) {
return { x: instance.x, y: instance.y };
}
static [WORKFLOW_DESERIALIZE](data: { x: number; y: number }) {
return new Point(data.x, data.y);
}
}
// Use in workflow and steps
export async function customSerializationWorkflow(x: number, y: number) {
'use workflow';
const point = new Point(x, y);
const scaled = await transformPoint(point, 2);
// ...
}
```
Run the e2e test to verify that class instances are properly serialized and deserialized.
### Why make this change?
Previously, user-defined class instances couldn't be passed between workflows and steps without losing their prototype chain and methods. This change allows developers to define custom serialization/deserialization logic for their classes, enabling proper reconstruction of instances with their full functionality intact when crossing workflow/step boundaries.
