* otel: explicit traceparent injection + linked-trace mode for bounded per-invocation traces
- Add WORKFLOW_TRACE_MODE ('linked' default, 'continuous' legacy) to the
workflow and step queue handlers. In linked mode, WORKFLOW_V2/STEP spans
start a new trace root with span links to the incoming delivery context
and the run-origin context, and re-enqueued messages forward the
ORIGINAL run-origin trace carrier unchanged.
- world-vercel now explicitly injects W3C traceparent/tracestate/baggage
headers on outgoing workflow-server HTTP requests from inside the
client span (no-op without an OTEL SDK registered).
- New workflow.trace.mode span attribute; unit tests for both modes and
for header injection.

* otel: human-friendly span names for workflow and step spans
WORKFLOW_V2/STEP prefixes with full machine names (workflow//./src/...//fn)
become workflow.execute / step.execute / workflow.start with the short
function name. New workflowDisplayName/stepDisplayName helpers in
@workflow/utils handle both raw and queue-sanitized name forms; full names
remain in the workflow.name/step.name attributes.

* address review: empty carriers, shared trace helpers, mode warning, name edge cases, consumer span kind
- Treat an empty ({}) trace carrier as absent everywhere the trace-mode
logic branches, so linked mode falls back to a fresh origin instead of
forwarding a useless {} forever; workflow.trace.propagated now reports
whether a usable carrier arrived.
- Extract the duplicated linked-mode logic into shared telemetry helpers
getNextTraceCarrier() and buildInvocationSpanLinks(), used by both the
workflow and step queue handlers; resume-hook now uses
linkToTraceCarrier (gaining the isSpanContextValid guard).
- Warn once per distinct unrecognized WORKFLOW_TRACE_MODE value instead
of silently selecting linked.
- shortNameFromSanitized: map default/__default to the module short name
(mirroring parseName) and document the `$`-sanitization limitation.
- Queue-delivered workflow.execute spans now use the CONSUMER span kind,
matching queue-delivered step.execute spans; docs span table and
changeset updated accordingly.

* 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`

* Introduce structured context-violation errors + Ansi renderer
Phase 1: Add Ansi rendering helpers (frame, hint, note, help, code, inline)
to @workflow/errors, and a chalk mock for readable snapshot tests.
Phase 2: Add four context-violation error classes to @workflow/core
(NotInWorkflowContextError, NotInStepContextError,
NotInWorkflowOrStepContextError, UnavailableInWorkflowContextError)
and apply them to all twelve user-facing throw sites so errors now
include docs links and a structured "what/why/fix" frame.
Co-Authored-By: Claude Opus 4.7 <noreply@anthropic.com>
* Address review: tighten changeset, implement ansifyName, harden Ansi
- Tighten phase 1 changeset to a single sentence (per pranaygp review) and switch to double-quoted frontmatter (per Copilot + repo convention).
- Implement `ansifyName` to actually apply dim styling to workflow/ / step/ prefixes; add an `Ansi.dim` helper to `@workflow/errors` so callers don't need to import chalk directly.
- Remove the `void getWorkflowMetadata;` workaround in context-errors.ts by dropping the unused value import (we only needed the type and symbol).
- Render the plain-Error throw in `workflow/get-workflow-metadata.ts` with `Ansi.frame` + docs link so the VM path matches the structured-class styling from the sibling step path (still uses a plain Error to avoid the module-init cycle).
- Guard `buildUnderline` against zero-length markers so a stray empty token can't produce a negative `String.repeat` count.
* Structured runtime logger metadata + fold in replay-timeout logging
Adds a `.child()` and `.forRun(runId, workflowName)` child-logger API to
the structured logger so runtime/step code doesn't have to repeat
`workflowRunId`/`workflowName`/`stepId` on every call. Normalizes error
metadata to structured `errorName` / `errorMessage` / `errorStack` fields
instead of ad-hoc `error: err.message` strings, and adds comments to
silent catches that swallow expected idempotency conflicts.
Also folds in the pending changes from #1812 so that PR can be closed:
- Standardize the console prefix to `[workflow-sdk]`.
- Split the replay-timeout log into a warn-while-retrying vs.
error-when-giving-up, and surface the underlying error when we can't
mark a timed-out run as failed.
- Include the error stack in the "Fatal runtime error during workflow
setup" log and in the top-level user-code workflow error log so the
stack surfaces in flattened log drains.
- Drop the `[Workflows] "<runId>" - ` prefix from
`buildWorkflowSuspensionMessage` — the structured logger now attaches
run context.
Supersedes #1812.

* Use double-quoted changeset frontmatter per repo convention
* Add SerializationError + apply to user-facing serialization sites
Phase 4 of friendlier errors: introduce a `SerializationError` class with
an optional `hint` and a docs link (workflow-sdk.dev/err/serialization-failed),
and adopt it at every user-facing serialization boundary in @workflow/core:
- Locked ReadableStream at a workflow boundary
- Unregistered class / missing `classId` / missing `WORKFLOW_DESERIALIZE`
- Attempting to return step functions to clients or call workflow functions
directly
- Webhook `respondWith()` called outside a step
- `dehydrate*` / `getSerializeStream` failures (workflow args/return, step
args/return, stream chunks)
Internal invariants (format prefix length checks, unknown format bytes,
missing `STREAM_NAME_SYMBOL`, encryption key/size guards, etc.) now throw
`WorkflowRuntimeError` instead of plain `Error` so the classifier and logger
treat them consistently.
`formatSerializationError` now returns `{ message, hint }` so the hint
fragment can be rendered with the standard SerializationError framing
instead of being baked into the message string.
Co-Authored-By: Claude Opus 4.7 <noreply@anthropic.com>
* Use double-quoted changeset frontmatter per repo convention
* Presentation-only user vs SDK error attribution
Add describeError() that derives attribution and class-aware hints from
existing error classes + RUN_ERROR_CODES — no event data changes. Wire into
step failures, max-delivery exhaustion, run failures, and fatal setup errors
so terminal logs include errorAttribution and a hint for known error types.
Co-Authored-By: Claude Opus 4.7 <noreply@anthropic.com>
* Address review: describeError accepts precomputed errorCode + instanceof
- `describeError(err, errorCode?)` now accepts an optional precomputed
`RunErrorCode`. `classifyRunError(err)` only narrows to USER_ERROR /
RUNTIME_ERROR, so the REPLAY_TIMEOUT and MAX_DELIVERIES_EXCEEDED branches
were previously unreachable from the step / run failure log sites.
Callers that know the failure category (runtime.ts for replay timeout and
max-deliveries exhaustion) now pass the code in.
- Context-violation checks use `instanceof` against the actual classes from
context-errors.ts instead of a name-string set. Type-safe + survives
class renames.
- Wire the new hints through to the REPLAY_TIMEOUT and MAX_DELIVERIES_EXCEEDED
log sites so those branches actually render a hint now.
- 3 new tests cover the reachable code paths + precomputed-code override.
- Changeset frontmatter switched to double quotes per repo convention.
* Cosmetic consistency pass on remaining bare throws
Internal invariants now use WorkflowRuntimeError so describeError attributes
them to the SDK: missing startedAt, VM generateKey, closure-vars outside
step context, ENOTSUP. defineHook().resume() formats schema validation
failures as a readable list instead of a JSON blob.
Co-Authored-By: Claude Opus 4.7 <noreply@anthropic.com>
* Use double-quoted changeset frontmatter per repo convention
* Data-driven describeRunError + expose via @workflow/core/describe-error
Observability renderers read persisted run_failed / step_failed event data,
not live Error instances. describeRunError takes { errorCode, errorName }
and returns the same { attribution, hint } shape as describeError, so the
CLI and web UI can derive user-vs-SDK framing from the event log directly.
Co-Authored-By: Claude Opus 4.7 <noreply@anthropic.com>
* Friendlier build-time errors: WorkflowBuildError class + applications
Add `WorkflowBuildError` class in `@workflow/errors` with optional `hint`
for an actionable next step, and apply it in `@workflow/builders` at
user-facing sites: failed esbuild phases, unresolved built-in steps, and
empty esbuild output now throw `WorkflowBuildError` with a hint pointing
at the likely fix. Runtime invariants remain plain `Error`.
* Polish friendlier-errors rendering: drop functionName leak, simplify docs link, redirect stack
- Drop the readonly `functionName` param-property on context-error classes so
util.inspect no longer prints a trailing `{ functionName: 'foo()' }` block.
- Replace the `DocLink` ("label: https://…") shape with a plain `DocsUrl`
template-literal type. Error output now renders a single clean line:
`docs: https://…` (new `Ansi.docs` helper) instead of the noisier
"note: Read more about foo(): https://…".
- Add throw helpers (`throwNotInWorkflowContext`, etc.) that call
`Error.captureStackTrace(err, stackStartFn)` on V8 engines so the top frame
of the thrown error points at the user's call site instead of at the gate
function inside the framework. Callers pass themselves as the boundary.
- Refactor `defineHook()` (both root and `/workflow`) to use named function
closures rather than `this.create`/`this.resume`, since the stack redirect
relies on a stable function identity that survives destructuring.
- Update context-errors.test.ts to snapshot the new `docs:` framing and to
add a regression test asserting the top stack frame is the user call site.
* Consolidate friendlier-errors stack: fix ANSI leak + non-retry semantics
Addresses PR review feedback across the 8-phase friendlier-errors stack and
fixes issues surfaced by manual testing (createHook() inside a step):
- ANSI no longer leaks into .message / .stack. Context-violation errors
now store plain text on .message and render the colored framed form
lazily via [util.inspect.custom] / toString(). Structured logs, log
drains, CBOR-serialized events, and JSON payloads no longer contain
raw \x1B[...m bytes.
- Context violations are now fatal. ContextViolationError sets
fatal = true; FatalError.is(err) recognizes any error with a
fatal: true own property. Calling createHook() from a step no longer
burns three retry attempts on a guaranteed-to-fail context violation.
- Ansi helpers moved to @workflow/errors/ansi subpath so imports from
@workflow/errors no longer pull chalk into consumers that only want
error classes (addresses reviewer VaguelySerious).
- Shared redirectStackToCaller helper in packages/core/src/capture-stack.ts,
used by both context-errors.ts and workflow/get-workflow-metadata.ts
(addresses Copilot review on #1849).
- Structured framed content: ContextViolationError now takes a structured
FramedContent (title segments + detail branches) and renders plain/pretty
from the same source of truth.
Tightens the eight existing phase changesets to 1-2 sentences each and adds
four new scoped changesets (errors-ansi-subpath, context-errors-plain-message,
context-errors-fatal, capture-stack-shared) for the followup fixes, so the
final changelog history stays readable.
* test: update step-handler mocks for scoped forRun() logger
The runtime logger now uses .forRun(runId, name, {stepId, stepName})
to attach scope context, so 409-handling log calls no longer repeat
{workflowRunId, stepId} in every metadata bag — those live on the
scoped logger instance. Update the mock to return itself from forRun()
and tighten assertions to check both the log args (errorName/errorMessage)
and the forRun() scope.
Co-Authored-By: Claude Opus 4.7 <noreply@anthropic.com>
* Mark SerializationError fatal + route dehydration through step-failure path
SerializationError now carries readonly fatal = true. Step-return
dehydration is wrapped inside the user-code try/catch so that the
resulting error flows through userCodeFailed → step_failed →
FatalError.is() short-circuit instead of bubbling up as HTTP 500 and
triggering a queue retry loop. Retrying a step that returned a non-POJO
is guaranteed to fail the same way, so this saves ~20s and 3 near-
identical error blocks per serialization failure.
* Add logging snapshot tests + manual-test artifacts
Snapshot tests lock in the exact shape of:
- describeError() payloads (attribution, errorCode, hint) for every
classification — plain Error, SerializationError, context-violation,
WorkflowRuntimeError, REPLAY_TIMEOUT, MAX_DELIVERIES_EXCEEDED.
- The scoped-logger call signature for the two canonical runtime
failure paths (fatal-bubble and hit-max-retries), so refactors of
forRun() / child() metadata merging can't silently change what users
see in their log drains.
SerializationError now also has a direct test for readonly fatal=true
+ FatalError.is() recognition.
pr-artifacts/ contains real log-output snapshots from running the
nextjs-turbopack workbench against five error scenarios. These are
reference material for reviewers and are flagged to be removed before
merge.
* Readable step-fatal logs: inline stack + friendly step/workflow names
The step-level fatal-error log used to embed the full stack trace inside
an `errorStack` string field in the metadata object, so util.inspect
rendered it as a quote-escaped, line-continuation blob when the log
hit the terminal — unreadable in practice. Move framing + stack into
the log *message* (matching the workflow-level log in runtime.ts) and
keep the metadata object compact with only the indexable structured
fields (`errorAttribution`, `errorName`, `errorMessage`, `hint`,
IDs). Log drains still get the same keys; humans now see a readable
stack trace.
Also introduce `formatStepName` / `formatWorkflowName` in
`@workflow/utils` that render machine names
(`step//./workflows/1_simple//add`) as `add (./workflows/1_simple)` in
log framings, using the existing `parseStepName` / `parseWorkflowName`
parsers. Applied to step-fatal, hit-max-retries, exceeded-max-retries,
and workflow-threw log sites.
Artifacts in pr-artifacts/ updated to show the new output shape, and
renamed .log → .md since they're Markdown and IDE previews are nicer
that way.
* Opinionated pretty formatter for runtime structured-log metadata
Replace util.inspect's default object dump (which quote-escapes
multi-line stacks and paragraph hints into a single-line JSON-y blob)
with a workflow-aware formatter that composes the entire log line
into a single string passed to console.error / console.warn.
Highlights of the new output:
- Per-run / per-step IDs render with their parsed friendly names so
users see `wrun_… · simple (./workflows/1_simple)` instead of just
the raw `workflowName: 'workflow//./workflows/1_simple//simple'`.
- Color-coded attribution badge (user error red / sdk error magenta)
paired with the error class in bold.
- Hints render as a paragraph under `hint:` rather than a backslash-
`\n`-escaped string.
- Drops redundant fields (errorStack always; errorMessage when it's
already in the parent message) to avoid double-printing.
- Unknown fields fall through as a sorted `key value` tail so we
never silently drop log information.
@workflow/errors/ansi gains bold/red/magenta helpers used by the
formatter. The web / web-shared packages don't consume stderr — they
read structured event payloads from the World event log — so this is
presentation-only at the runtime layer.
* ci(benchmarks): disable pnpm cache for getCommunityWorldsMatrix
The job never runs `pnpm install` (it just calls `node` against a
checked-in script), so the pnpm store path never exists. The post-job
`actions/setup-node@v4` cache-save then fails with `Path Validation
Error: Path(s) specified in the action for caching do(es) not exist`
and red-X's the entire job even though the matrix step succeeded.
The setup-workflow-dev composite already has a `cache-pnpm` opt-out
input for this exact case — wire it through here.
* Address PR review comments: inspect dedup, cause leak, retry-loop tests
- ContextViolationError: util.inspect(err) duplicated every framed detail
line because the stack-tail strip only sliced the first message line.
V8's Error.stack reads `Name: messageLine1\n messageLine2\n at ...`,
so for our multi-line `title\n╰▶ docs: …` messages every detail line
was getting prepended twice (once in the pretty form, once via the
unsliced message tail). Count the actual message lines and slice past
all of them. Repro test asserts `╰▶ docs:` appears exactly once.
- WorkflowError: stop assigning `cause: undefined` as an enumerable own
property when no cause is provided. Subclasses (every error in this PR)
inherit the parent constructor; the unconditional assignment polluted
`util.inspect(err)` output with `{ cause: undefined, … }` on every
no-cause instance. The `super(...)` call already conditionally sets
`.cause` non-enumerably when `options.cause` is provided.
- step-handler.test.ts: add a regression-gate suite that exercises the
fatal-vs-retryable retry-loop wiring directly. Asserts that an error
with `fatal: true` produces exactly one `step_failed` event with no
`step_retrying`, and that a non-fatal `Error` retries via
`step_retrying` on early attempts and emits `step_failed` once the
retry budget is exhausted. Catches the silent-regression case where
`fatal = true` is removed from a context-violation error class but
the `FatalError.is()` unit tests stay green.
* Consolidate changesets + remove pr-artifacts
Address review feedback to drastically shorten the changesets — fold
the 15 file-by-file entries into a single user-facing changeset for
@workflow/core / errors / builders / utils. Also drop the pr-artifacts/
folder (reviewer-only log captures, no longer needed).
* Polish runtime error logging: layout, stack trim, hint consolidation
Five user-driven fixes from manual smoke-testing of #1849:
1. Logger layout. composeLogLine() now puts the structured-fields block
(attribution badge, run/step IDs, error code) **between** the framing
line and the stack body, instead of after it where 30+ lines of stack
buried the most useful information. The framing stays at the top,
stack at the bottom, structured info readable at a glance.
2. Stack trim. Drops framework-internal frames (`node_modules/.pnpm/`,
`node:internal/`, Turbopack-bundled `node_modules__pnpm_*` chunks,
`_next_dist_*` chunks) and caps the surviving frame count at 6
so the stack stays compact even on heavy async wrappers. Suppressed
runs emit one summary line so users know the trim happened.
3. Wrapper-route noise. The nextjs-turbopack workbench's start route
was catching `WorkflowRunFailedError` rejection on
`Promise.race([readLoop(), run.returnValue])` and re-logging it via
`console.error('Error in workflow stream:', error)` plus
`controller.error(error)` — which then triggered Next.js's
`⨯ failed to pipe response` overlay. The SDK already logs the
failure cleanly upstream and the runId is on the response header, so
the wrapper now closes the SSE stream cleanly on
WorkflowRunFailedError.
4. Consistent framed `╰▶ hint:` / `╰▶ docs:` layout for all errors
that carry a hint or docs slug. WorkflowError, SerializationError,
and WorkflowBuildError now share one `appendFramedDetails` helper
matching the box-drawing structure that ContextViolationError
already used. Was: blank-line-separated `Learn more: <url>`. Now:
one tree, indistinguishable from context-violation rendering.
5. Drop the duplicate logger-side `hint` field. Hints now live on the
error message only — actionable hints get serialized into the event
log, rehydrated on the workflow side, and shown in observability
automatically. The previous logger-only hint duplicated stderr but
never made it past the step boundary.
Updated SerializationError hint to point at the foundations doc
("Ensure you're returning workflow serializable types. Check the
serialization docs to see what's serializable:
https://workflow-sdk.dev/docs/foundations/serialization") instead
of the hardcoded `(plain objects, arrays, primitives, …)` list,
which drifted out of sync as the supported types grew. Same hint
reuses for step args, workflow args/return, stream messages, and
any other site that goes through `formatSerializationError`.
Also retitled the retry summary `3 retries` → `3 max retries` since
"3 retries" next to "4 attempts" was ambiguous (already-happened vs.
budget).
* Trim error-card title + drop machine step name from persisted error
- ErrorStackBlock (web observability): show just the first non-empty
trimmed line of the error message in the card title with single-line
truncation. Multi-line messages (`Failed to serialize step return
value\n╰▶ hint: …`) were rendering the entire framed body in the
title, pushing the copy button off-screen and burying the
scannability of the headline. Full message stays in the body via
the stack (V8 prepends `Name: message` to `Error.stack`), so no
information is lost; hover-tooltip exposes the full title text.
- Persisted error message: drop the `Step "step//./.../foo"` machine
name from `Step failed after N retries: …` and `Step exceeded max
retries (…)` strings. Observability already attributes the event
to a specific step via the UI tree, and the CLI logger emits the
friendly `Step foo (./...) hit max retries` framing on its own
line. Embedding the raw `step//./...` machine name in the persisted
message text was duplicate noise.

* Update SerializationError snapshot tests for slug-less message
The class no longer attaches a slug-based `╰▶ docs:` line — the
foundations URL is embedded directly in the hint via the
`formatSerializationError` helper in @workflow/core. Update the test
expectations accordingly:
- bare-title case is now a single line (no docs link)
- hint case renders one `╰▶ hint: …` branch (no second branch)
* Update serialization.test.ts hint assertions for foundations URL
Four `should throw error for an unsupported type` cases were still
asserting on the old hardcoded type list. Update to the new hint
phrasing that points at the foundations doc, matching the change in
`formatSerializationError` (`packages/core/src/serialization/errors.ts`).

* feat: serialize Run via custom class serialization with "use step"
Single Run class implementation:
- Add WORKFLOW_SERIALIZE/WORKFLOW_DESERIALIZE to core Run class
- Mark all runtime-dependent methods/getters with "use step" so SWC
strips their bodies from the workflow bundle
- Remove duplicate Run stub from api-workflow.ts; re-export core Run
- SWC auto-registers the class (no manual registerSerializationClass)
- Add e2e test for Run serialization across workflow/step boundaries
- Add unit tests for serde roundtrip
* chore: bump changeset to minor (new feature)
* fix: include resilientStart in Run serde payload and add readable getter comment
* .
* fix: remove eager getWorld() from constructor, rely on lazy getter
The SWC compiler plugin no longer generates import statements. All step
function registrations and closure variable access are now self-contained
inline IIFEs with zero module dependencies
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.
* fix: check target run capabilities before encrypting hook payloads
When resumeHook()/resumeWebhook() is called on a newer deployment that
supports encryption, it would encode the payload with the 'encr' format.
If the target workflow run was created by an older deployment that
predates encryption support, the run would fail with:
Error: Unknown serialization format: "encr". Known formats: devl
Add a capabilities table that maps @workflow/core versions to supported
serialization formats. Before encoding, resumeHook() now checks the
target run's workflowCoreVersion and suppresses encryption when the
run's deployment doesn't support it.
* address review: guard against invalid/non-string workflowCoreVersion
- Validate with semver.valid() before comparing, falling back to
baseline formats for malformed version strings
- Add typeof guard at the call site in resumeHook() since
executionContext is Record<string, any>
- Add tests for invalid version strings (dev, empty, partial, etc.)
- Add encryption commit reference to capabilities module header
* 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.

- 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

* 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

* refactor: use `this` value serialization for builtin step functions
Refactor builtin step functions (__builtin_response_json, _text,
_array_buffer) to use `this` instead of an explicit parameter,
leveraging the useStep() proxy's this value serialization support.
- Assign useStep() proxies directly onto Request.prototype and
Response.prototype instead of wrapping them in class methods
- Update builtin function signatures to use `this: Request | Response`
- Remove unused duplicate builtins file from @workflow/core
(the canonical copy lives in workflow/src/internal/builtins.ts)
* use Object.defineProperties for non-enumerable prototype methods
