feat(cli): print run deep links with --url, fix dashboard route (#2467)
Add a `--url` flag to `inspect`/`web` that prints a run's observability dashboard deep link to stdout and exits — no browser, no local server — so scripts and agents can share a link instead of opening a UI. Fix the Vercel dashboard URL to the current `…/workflows/runs/<id>?environment=<env>` route (drop the legacy `/observability` segment) and respect `--env`. Apply the same route fix to the e2e helpers, CI aggregation scripts, and the nextjs-turbopack workbench. Document deep-linking in the workflow skill and observability docs.

RFC: compress serialized payload refs — zstd (gzip fallback), specVersion 5 (#2394)
* feat(core,world): gzip-compress serialized payloads behind specVersion 5 Add a composable 'gzip' format prefix layer to the serialization pipeline (compress before encrypt: encr(gzip(devl))), cutting stored payload bytes by ~70-87% on real-world-style workloads. Compression is gated on run specVersion 5 (new SPEC_VERSION_SUPPORTS_COMPRESSION) and on target-deployment capabilities for cross-deployment writes; payloads under 1KB or that don't compress meaningfully are stored unchanged. Reads dispatch on the format prefix so both compressed and uncompressed data are always readable. WORKFLOW_DISABLE_COMPRESSION=1 disables writes. Co-Authored-By: Claude Fable 5 <noreply@anthropic.com> * test(core): add CPU/perf compression benchmark + shared workloads Split the compression benchmark into reproducible size and CPU scripts sharing deterministic workloads (lib/workloads.mjs). The CPU benchmark measures serialize/deserialize overhead per payload, total CPU across thousands of events, and compares gzip levels/brotli/deflate. Documents how to run the size, CPU, and end-to-end (bench.bench.ts) benchmarks against local and Vercel in scripts/README.md. Co-Authored-By: Claude Fable 5 <noreply@anthropic.com> * feat(world-vercel): advertise specVersion 5 to enable compression on Vercel Now that workflow-server declares spec-5 support (vercel/workflow-server#520), bump the Vercel world's advertised specVersion from 4 to 5 so new Vercel runs are stamped spec 5 and become eligible for gzip payload compression. Payloads stay opaque to the server (compression is client-side); spec 5 is a superset of spec 4, so initial run attributes still work. Co-Authored-By: Claude Fable 5 <noreply@anthropic.com> * feat(core): emit OTel span attributes for compression impact Track gzip payload compression on both the serialize (write) and deserialize (read) paths via span attributes: workflow.serialization.{operation,compressed,uncompressed_bytes, stored_bytes,compression_ratio}. Sizes are measured at the compression boundary (pre-encryption), so they reflect compression's effect rather than the at-rest size. The compression codec stays pure — compress/decompress optionally populate a CompressionStats sink, threaded through CodecOptions to the mode serializers and read by the dehydrate/hydrate wrappers, which set attributes on the active span. Telemetry failures are swallowed so they can never break the serialize/deserialize data path. Co-Authored-By: Claude Fable 5 <noreply@anthropic.com> * feat(core,web-shared): prefer zstd compression codec (gzip fallback) Switch the payload compression codec to zstd, which benchmarks 3–7× faster than gzip at an equal-or-better ratio on representative workloads (compression runs at every step boundary, so the write CPU is a per-step tax). zstd uses node:zlib (>= 22.15); gzip via the portable CompressionStream remains the fallback when zstd is unavailable, and WORKFLOW_COMPRESSION_CODEC=gzip forces it. Reads dispatch on the format prefix, so 'zstd' and 'gzip' payloads are both always decodable. zstd is Node-only (Web CompressionStream has no zstd), so the browser o11y read path registers a WASM-backed decoder (@tootallnate/zstd-wasm) via a new registerZstdDecoder hook; node:zlib handles Node-side reads (runtime replay, CLI, server o11y). A new workflow.serialization.codec span attribute reports which codec applied. gzip and zstd read support co-ship, so the existing specVersion-5 capability gate is unchanged. Verified end-to-end: spec-5 runs store zstd-prefixed payloads on disk and replay/complete correctly; the WASM decoder round-trips node:zlib zstd output. Benchmarks updated to compare zstd vs gzip.

fix(core): make deploymentId 'latest' a no-op in non-Vercel worlds (#2397)
* fix(core): make deploymentId 'latest' a no-op in non-Vercel worlds
Previously, start({ deploymentId: 'latest' }) threw a WorkflowRuntimeError
in any World that doesn't implement resolveLatestDeploymentId() (local dev,
Postgres). That meant a workflow which opts into 'latest' on Vercel would
fail outright in local development.
Resolving 'latest' only means something in worlds with atomic, immutable
deployments. In other worlds there is nothing to resolve between, so instead
of throwing we now log a warning and fall back to the current deployment,
making 'latest' an effective no-op there.
- start.ts: warn + fall back to currentDeploymentId instead of throwing
- start.test.ts: replace the "should throw" test with a warn + fallback test
- e2e.test.ts: assert 'latest' completes (no-op) on non-Vercel worlds
- docs: note the no-op behavior in v4 + v5 start.mdx
Co-Authored-By: Claude Opus 4.8 <noreply@anthropic.com>
* fix(core): warn once for deploymentId 'latest' no-op; harden test cleanup
Address PR review:
- Gate the 'latest'-has-no-effect warning behind a once-per-process guard
(mirrors the warnOnce pattern in constants.ts) so a workflow that hardcodes
'latest' for Vercel doesn't flood local/Postgres dev logs on every run.
Exposes _resetLatestNoOpWarnForTests() (@internal) for unit tests.
- start.test.ts: reset the guard in beforeEach and restore spies in afterEach
via vi.restoreAllMocks() so a throwing assertion can't leak the
runtimeLogger.warn spy into later tests; drop the manual mockRestore().
- Add a test asserting the warning fires exactly once across repeated
'latest' starts while every run still falls back to the current deployment.

otel: explicit traceparent injection + linked-trace mode for bounded per-invocation traces (#2363)
* 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.
Co-Authored-By: Claude Opus 4.8 (1M context) <noreply@anthropic.com>
* changeset: call out behavioral telemetry changes of the linked default
Co-Authored-By: Claude Opus 4.8 (1M context) <noreply@anthropic.com>
* docs: add v5 observability tracing page
Documents OTEL spans/attributes, linked trace mode and WORKFLOW_TRACE_MODE,
span links, context propagation, and the v4 behavior-change callout.
Co-Authored-By: Claude Opus 4.8 (1M context) <noreply@anthropic.com>
* 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.
Co-Authored-By: Claude Opus 4.8 (1M context) <noreply@anthropic.com>
* changeset: merge span-name and linked-trace notes into one changeset
Co-Authored-By: Claude Opus 4.8 (1M context) <noreply@anthropic.com>
* docs: update trace-shape prose to renamed span names
Co-Authored-By: Claude Opus 4.8 (1M context) <noreply@anthropic.com>
* docs: replace ascii trace diagram with mermaid
Co-Authored-By: Claude Opus 4.8 (1M context) <noreply@anthropic.com>
* 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.

Co-Authored-By: Claude Fable 5 <noreply@anthropic.com> * docs: detect the concurrent-start race via runId comparison instead of awaiting returnValue The 'Resume or Start' example returned the just-started run's runId with reused: false even when a concurrent request's run won the token race — the payload had reached the actual owner, so the response pointed callers at a run that exits as a duplicate. The foundations route handled the race correctly but by awaiting run.returnValue, blocking the HTTP response on full workflow completion. resumeHook() always resolves against the actual active owner, so comparing the resumed hook's runId with the started run's runId detects the race in both examples — race-correct and non-blocking. * feat: replace hook.hasConflict with hook.getConflict (Promise<Run | null>) hasConflict's boolean didn't expose WHICH run owns the token, so the duplicate run couldn't act on the conflict. getConflict resolves with null once registration commits, or with a Run handle for the conflicting run — letting the workflow return/log the owner's runId, inspect its status, await its result, or cancel it and continue, all in code. The workflow-mode create-hook module exposes the bundle's compiled Run class (durable step-proxy methods) on a well-known symbol so the host- side hook consumer can construct the conflicting run inside the VM.

fix(docs): repair broken links, fix the link linter, and version-correct v5 Card + edit links (#2391)
* fix(docs): repair broken links and make the docs link linter actually validate The docs link linter (docs/scripts/lint.ts) had been silently passing everything since the app moved under app/[lang]/ (#552): the next-validate-link populate key 'docs/[[...slug]]' no longer matched the real route, and the unpopulated [lang] homepage route produced a fallback regex (^\/(.+)$) that matched every href. It also only scanned v4 content. - Rewrite lint.ts to build explicit v4/v5 URL spaces from both fumadocs sources (including cookbook URL variants, app routes, worlds pages, public/ assets, and next.config.ts redirects) and validate each version's content against version-correct render semantics. Also validate frontmatter related/prerequisites references (version-relative) and heading fragments. - Rewrite Card hrefs on v5 pages: the v5 routes rewrote inline markdown links from /docs/... to /v5/docs/... but Card renders its own Link, so Card hrefs escaped to the v4 routes and 404'd for v5-only pages (e.g. /v5/docs/observability linking to /docs/observability/attributes). - Fix all dead content links surfaced by the working linter (56 across v4+v5): nonexistent use-workflow/use-step/start API pages now point at foundations/workflows-and-steps and workflow-api/start, getStepMetadata path corrected, /docs/worlds/local → /worlds/local, dead changelog/ internal references removed or unlinked, retired common-patterns links point at the cookbook, and a dead #returnvalue anchor now targets #returns. - Add an index page for api-reference/workflow-errors (both versions), which was linked from the API reference landing page but had no page. 🤖 Generated with [Claude Code](https://claude.com/claude-code) Co-Authored-By: Claude Fable 5 <noreply@anthropic.com> * fix(docs): add version prefix to 'Edit this page on GitHub' links All "Edit this page on GitHub" links 404'd since the v4/v5 content split (#1948): page.path is relative to the per-version content dir, but EditSource built URLs against docs/content/docs/ without the v4/ or v5/ segment.

Add allowReservedAttributes option to start() (#2385)
* Add allowReservedAttributes option to start() experimental_setAttributes already exposes allowReservedAttributes for framework-level callers that own a $-prefixed sub-namespace, and the run_created / run_started event schemas plus the local and Postgres worlds already accept and validate the flag. start() was the one gap: it always validated initial attributes with the reserved prefix disallowed and had no way to opt out, so framework code could not seed reserved attributes at run creation. Thread the option through start(): - StartOptions.allowReservedAttributes, passed to client-side validation and forwarded on the run_created eventData - carried in the queue runInput (new RunInputSchema field) and forwarded to run_started so the resilient/lazy run creation path validates identically Co-Authored-By: Claude Fable 5 <noreply@anthropic.com> * Add e2e coverage for reserved initial attributes via allowReservedAttributes Verified locally against the nextjs-turbopack dev server: the reserved key passes client and server validation, lands on the run at creation, and survives the workflow's own attr_set writes.

fix(docs): right-align sidebar folder carets consistently (#2377)

Replace hook.hasConflict with hook.getConflict() returning the conflicting Run (#2373)
* feat: replace hook.hasConflict with hook.getConflict (Promise<Run | null>)
hasConflict's boolean didn't expose WHICH run owns the token, so the
duplicate run couldn't act on the conflict. getConflict resolves with
null once registration commits, or with a Run handle for the conflicting
run — letting the workflow return/log the owner's runId, inspect its
status, await its result, or cancel it and continue, all in code.
The workflow-mode create-hook module exposes the bundle's compiled Run
class (durable step-proxy methods) on a well-known symbol so the host-
side hook consumer can construct the conflicting run inside the VM.
Contexts without the class (plain unit tests) fall back to a { runId }
object, which is also the documented v4 shape (no native Run
serialization in v4).
Co-Authored-By: Claude Fable 5 <noreply@anthropic.com>
* fix: never resolve getConflict with a non-Run fallback shape
getConflict's contract is Promise<Run | null>. In the degenerate cases
where a real Run cannot be constructed — a hook_conflict event persisted
by an old world without conflictingRunId, or a context that never loaded
the workflow-mode create-hook module — reject with HookConflictError
instead of resolving with a { runId }-shaped impostor.
Test harnesses now register the Run class on the (VM) globalThis like
real bundles do.

Co-Authored-By: Claude Fable 5 <noreply@anthropic.com>
* review: guard Run class registration, fix anchors, clarify changeset
- Only register WORKFLOW_RUN_CLASS when the workflow runtime is present
(WORKFLOW_CREATE_HOOK installed on globalThis), so host imports of the
workflow-mode module neither mutate the host global nor expose the
non-step-proxy host Run.
- Drop #run-idempotency link fragments — that section lands in the
stacked docs PR (#2011), which restores the anchored links.
- Note in docs that getConflict() rejects with HookConflictError for
legacy hook_conflict events lacking the owner's run ID.
- Changeset now calls out the hasConflict -> getConflict() replacement.
Co-Authored-By: Claude Fable 5 <noreply@anthropic.com>
* refactor: resolve the conflicting Run through the serialization class registry
Replace the bespoke WORKFLOW_RUN_CLASS global with the registry the
serialization pipeline already uses to revive Run instances:
- The SWC plugin already auto-registers the workflow bundle's compiled
Run in globalThis[workflow-class-registry], but under a path-derived
classId the host cannot know statically. The workflow-mode create-hook
module now aliases it under a stable id (class//workflow//Run) via a
new aliasSerializationClass() helper (a plain registry entry —
registerSerializationClass cannot be reused since the plugin's IIFE
already defined the non-configurable classId property).
- createConflictingRun() looks the class up with
getSerializationClass(RUN_CLASS_ID, ctx.globalThis) and constructs
through its WORKFLOW_DESERIALIZE hook, exactly as the Instance reviver
would for a serialized Run crossing from a step into the workflow.
- Because the registry is keyed per-global, no environment guard is
needed: a stray host-side import registers the host Run on the host
registry, which is the correct class for that context. The
WORKFLOW_CREATE_HOOK guard, the ??=, and the WORKFLOW_RUN_CLASS symbol
are all deleted.
Verified: 1156 core unit tests; compiled workbench bundle contains the
stable alias alongside the plugin's path-derived registration with zero
WORKFLOW_RUN_CLASS references; all 5 hookGetConflict e2e tests pass
against a local nextjs-turbopack dev server, including conflict
resolution reading conflict.status through a durable step.

[core] V2: unify wait+step queue dispatch in suspension processing (#1925)
* [core] V2: pre-schedule the wait timer before inline-executing a step Fix `Promise.race(step, sleep)` semantics in V2 mixed suspensions without losing inline step execution. Inline `await executeStep(...)` blocks the V2 handler for the full step duration, but `wait_completed` events are only created on the *next* loop iteration's "complete elapsed waits" pass. So if the sleep is shorter than the step, replay always picked the step because the wait_completed event hadn't been written yet — `sleepWinsRaceWorkflow` returned `'step'` instead of `'sleep'`. Fix: when a suspension contains both an owned inline step and at least one pending wait, queue a delayed self-message with `delaySeconds = suspensionResult.timeoutSeconds` *before* starting inline execution. The queued continuation fires in a separate function invocation while the step is still running. That parallel invocation's "complete elapsed waits" pass writes wait_completed, replay observes the elapsed wait, and `Promise.race` resolves with the sleep correctly. The original (still-running) inline invocation finishes its step, sees `run_completed` on the next loop iteration, and exits. This preserves inline-step execution speed for the step-wins case: the step finishes inline and the workflow returns directly. The eagerly-queued wait continuation fires after the step has won and just no-ops on the terminal run. Test plan: - New e2e tests `sleepWinsRaceWorkflow` and `stepWinsRaceWorkflow` exercising `Promise.race` between a step function and `sleep()`, in both directions. - Verified locally against `nextjs-turbopack` workbench: both pass. Event log confirms `wait_completed` is created at t≈1s after `wait_created` (1s sleep) instead of at t≈11s after the inline step finishes. Eager-processing changelog updated with a "Mixed Suspensions" section describing the pre-scheduled wait approach and its rationale. Co-Authored-By: Claude Opus 4.7 (1M context) <noreply@anthropic.com> * [world-local] Honor delaySeconds before message delivery The local queue's `queue()` enqueue path ignored the `delaySeconds` option entirely — every message was delivered immediately, regardless of the requested delay. VQS-side queues (used by world-vercel and world-postgres) honor delaySeconds at the broker, so this brings world-local in line with production semantics. The runtime needs this to land before the wait-as-continuation unification in the next commit: that change starts queueing wait timers as fresh delayed continuations instead of returning `{ timeoutSeconds }`. Without delaySeconds support, those wait continuations would fire instantly in dev and trigger spurious replays. Sleep happens outside the queue's worker semaphore so a delayed message doesn't tie up a worker slot during its delay window — other immediate messages are free to dispatch in parallel. New tests in queue.test.ts cover: - delaySeconds > 0 → setTimeout called with the right ms value - delaySeconds === 0 → no setTimeout (immediate dispatch) - delaySeconds omitted → no setTimeout (immediate dispatch) * [core] V2: unify wait+step queue dispatch in suspension processing Replace the asymmetric "steps go to the queue, waits become a { timeoutSeconds } return value" pattern with a single Promise.all batch that queues every pending operation we are not running inline. Before this change, suspension processing had three branches that all needed to keep the wait/step asymmetry consistent: - pendingSteps.length === 0 returned { timeoutSeconds } - inlineStep + waits eagerly queued a delayed self-message AND set inlineStep to undefined (Option A) AND returned { timeoutSeconds } - inlineStep retry path returned { timeoutSeconds } if there were waits After this change, every suspension goes through one path: for non-inline pendingSteps: queue stepId message if timeoutSeconds defined: queue delayed continuation await Promise.all(dispatches) if !inlineStep: return await executeStep(inlineStep) Behaviorally, this restores inline step execution even when the suspension also has a wait (Option A's carve-out is no longer necessary): the wait timer fires in a separate function invocation on the queue, in parallel with the inline step. If the sleep wins the race, that parallel invocation observes wait_completed via the "complete elapsed waits" pass and finishes the run; if the step wins, the wait continuation fires later and no-ops on the terminal run via the existing terminal-event check. Other cleanups: - The inline-step retry path no longer needs to forward suspensionResult.timeoutSeconds — the wait timer was already enqueued as part of the unified dispatch above. - A dead post-step `if (timeoutSeconds && pendingSteps.length === 1)` block (just a comment, no body) is removed; the loop's "complete elapsed waits" pass handles the same case correctly. - Step queueing now uses a shared `traceCarrier` rather than re-serializing per step. Retry/throttle and hook-conflict paths still return { timeoutSeconds } since their semantics are "redeliver THIS message after a delay" rather than "schedule a fresh wait timer." Those can be unified in a follow-up. Test plan: - New e2e tests `sleepWinsRaceWorkflow` and `stepWinsRaceWorkflow` pass against the `nextjs-turbopack` workbench. - Event log inspection confirms wait_completed fires at t≈1s (after wait_created at t≈0s) for the sleep-wins case, and that the inline step runs only once (no duplicate step_started events that the earlier eager-queue approach produced in dev). - All 842 @workflow/core unit tests pass. - All 346 @workflow/world-local unit tests pass (with the delaySeconds support added in the previous commit). Requires the world-local delaySeconds fix in the prior commit; without it, wait continuations would fire instantly in dev and the parallel replay would re-enter handleSuspension before the wait elapsed (recoverable via existing redelivery, but inefficient). * [docs] V2 unified suspension dispatch + changeset Update the "Mixed Suspensions" section in eager-processing.mdx to describe the unified parallel-dispatch model: - All non-inline pendingSteps are queued with stepId - The wait timer (if any) is queued as a delayed continuation - All dispatched in one Promise.all batch - One owned step is then inline-executed (if any) The doc previously described Option A (the carve-out where waits forced all steps to be queued); the unified model removes that carve-out and explains why the wait continuation works in parallel with the inline step. Also notes the dependency on world-local's new delaySeconds support (landed earlier in the same PR series). Changeset bumps both @workflow/core and @workflow/world-local since both packages have user-observable behavior changes. * [core] Dedupe wait continuations on the wait's correlationId While a wait is pending, every replay pass over the run re-observes it (once per step completion in Promise.all([steps..., sleep()]), etc.) and would enqueue another delayed continuation — each a spurious replay when the wait elapses, and each a fresh message that resets the delivery-attempt runaway guard. Key the continuation on the wait's correlationId so the worlds' idempotency dedupe collapses them. Near-elapsed waits (<= 2s) are enqueued without the key: a continuation delivered marginally early (clock skew; the ceil() on the delay can leave a ~0 margin) re-observes its wait as pending and must be able to enqueue a fresh short-delay retry. VQS idempotency records persist until message-retention TTL — reusing the key there would drop the retry and stall the run permanently. Also adapts wait-completion-replay tests (from #2038) to the unified dispatch model: the hook-branch step now executes inline (registered in the test world, which now returns a step entity from step_started), so each scenario performs one extra loop-iteration event fetch. Co-Authored-By: Claude Fable 5 <noreply@anthropic.com> * [core] Always key wait continuations; bucket the key for near-elapsed waits CI caught sleepWinsRaceWorkflow failing across the world-postgres lanes: world-postgres serializes KEY-LESS workflow messages per run (inflightWorkflowRuns), so a key-less wait continuation parks behind the flow message that is inline-executing the racing step — wait_completed lands after step_completed and the race resolves to the step. Keyed messages take the concurrent dedupe path, so the continuation must always carry an idempotency key. The near-elapsed exception (<= 2s) now uses a second-bucketed suffix instead of omitting the key: an early-delivered continuation re-observes its wait as pending and re-enqueues with >= 1s delay, which guarantees a later bucket — a fresh key that dedupe windows cannot drop — while same-instant duplicates still collapse. Verified against a local world-postgres setup (express workbench, Graphile worker): sleepWins/stepWins pass 3/3 with wait_completed at t+1s; the event log confirms the continuation fires in parallel with the in-flight inline step. Co-Authored-By: Claude Fable 5 <noreply@anthropic.com> * [core] Clamp wait-continuation delays; chain long waits with hop-keyed dedupe Addresses PR review: the unified dispatch passed delaySeconds to the queue unclamped while keying the continuation on the bare wait correlationId. On world-vercel (23h max delay, 24h VQS message retention) a sleep() longer than the max either failed the dispatch or was delivered early with its re-enqueue silently dropped by the still-live idempotency record - stalling the run permanently. - New runtime/wait-continuation.ts owns delay + idempotency-key selection: delays clamp to 23h and longer waits chain across hops, with the hop index suffixed to the key so re-observations within a hop window dedupe while each hop delivery gets a fresh key. Near- elapsed threshold and max delay are named constants; full rationale moved out of the runtime.ts comment block. Unit tests pin the key selection including chain advancement. - SuspensionHandlerResult: timeoutSeconds/timeoutWaitCorrelationId collapsed into waitTimeout?: { seconds, correlationId } so the pairing can't drift (review nit). - runtime.test.ts ack-ordering harness adapted to the unified model: step_created now answers EntityConflictError so the handler observes the step without owning it and must queue it (the carve-out the tests relied on - "pending wait disables inline execution" - is exactly what this branch removes). Co-Authored-By: Claude Fable 5 <noreply@anthropic.com> * [world-local] Abort pending queue sleeps on close() Addresses PR review: a pending delayed message kept the dev process's event loop alive for its full delay, and close() only closed the HTTP agent - a sleep that fired afterwards attempted delivery against the closed agent and logged a spurious "[local world] Queue operation failed" error during test/CLI shutdown. One AbortController owned by the queue now cancels the delaySeconds sleep, the timeoutSeconds re-delivery sleep, and the retry backoff on close(); the resulting AbortError is already swallowed by the existing isAbortError check. close() is idempotent since shutdown paths may invoke it twice. Co-Authored-By: Claude Fable 5 <noreply@anthropic.com> * [docs] Wait-continuation clamping + hop chaining; changeset eager-processing.mdx pseudocode now shows the continuation's idempotency key and clamped delay (PR review nit); the dedupe prose covers the two key variations (hop suffix for chained long waits, second bucket for near-elapsed waits). Changeset mentions long-sleep chaining and world-local's abort-on-close.

Add native v4 workflow attribute events (#2226)
* Add native workflow attribute events * Fix abbreviated attributes docs sample * Document attribute replay ordering for step races * Address native attribute review feedback * Validate before claiming attr_set dedup lock; clearer start() attribute errors - world-local: claim the attr_set correlation lock only after validation, so a validation failure does not permanently mark the correlationId as written and wedge the run in a re-invoke loop on retry - world-postgres: distinguish a concurrently-deleted run from a cap violation when the guarded attributes update matches no rows - core: reject non-string initial attribute values in start() with a clear error instead of a downstream schema failure Co-Authored-By: Claude Fable 5 <noreply@anthropic.com> * Add attribute edge-case tests across all layers - core: normalizeAttributeChanges unit tests (non-object inputs, FatalError wrapping, key/value/batch limits, boundary lengths, UTF-8 byte counting) - core: start() rejects reserved keys, oversized keys/values, and over-cap initial attribute batches before any write - world-local + world-postgres: per-run cap enforced against existing attributes (upsert-at-cap allowed, removal frees room), oversized values rejected on attr_set, invalid initial attributes rejected on run_created - e2e: validation DX workflow asserting every invalid write throws a catchable FatalError naming the violated rule and limit, with the run staying healthy; start() rejects invalid initial attributes client-side Co-Authored-By: Claude Fable 5 <noreply@anthropic.com> * Remove accidentally committed local e2e diagnostics artifact Co-Authored-By: Claude Fable 5 <noreply@anthropic.com> * Bump world-vercel to spec version 4 for native attributes The deployed workflow-server (vercel/workflow-server#469) materializes native attr_set events and accepts initial run attributes, but world-vercel still advertised spec v3 — so start(..., { attributes }) rejected itself client-side ('requires spec version 4') on every Vercel deployment, failing the new e2e seeding test across the prod matrix. New runs are now stamped v4. Co-Authored-By: Claude Fable 5 <noreply@anthropic.com> * Reject duplicate correlated attr_set before materializing in Postgres A redelivered duplicate — including one carrying different changes for the same correlationId — previously re-applied the run attributes update and only then failed the event insert, leaving the snapshot out of sync with the event log. Pre-check the event log for the correlationId before mutating; the unique index still guards the truly-concurrent race, which is idempotent (deterministic replay carries identical changes). Also apply the suggested docs wording for initial attributes. Co-Authored-By: Claude Fable 5 <noreply@anthropic.com> * Apply suggestion from @VaguelySerious Signed-off-by: Peter Wielander <mittgfu@gmail.com> * Fail the run on World-rejected attribute writes; un-nest runtime test Two fixes from review: - runtime.test.ts: the pre-existing test "propagates transient step_created failures..." was accidentally nested inside the new attribute-race test, failing the new test ("Calling the test function inside another test function is not allowed") and preventing the old test from running. Restored it verbatim at describe level. - A workflow-body attr_set the World rejects as invalid (e.g. the cumulative per-run attribute cap, which only the World can check) is deterministic: redelivering the orchestrator message replays the same write into the same rejection, wedging the run in redelivery with no terminal event. handleSuspension now wraps such rejections in FatalError, and workflowEntrypoint fails the run with the validation error instead of rejecting the delivery. Transient storage errors still propagate and retry via redelivery.

fix(core,errors): classify SDK encryption failures as RUNTIME_ERROR (#2145)
* fix(core,errors): classify SDK encryption failures as RUNTIME_ERROR SDK-level AES-GCM encrypt/decrypt failures are never the user's fault, but the run-failure classifier was tagging them as USER_ERROR because the native Web Crypto OperationError (most commonly raised by AESCipherJob.onDone on GCM auth-tag mismatch) does not match any RUNTIME_ERROR_CHECKS entry. Introduce a new RuntimeDecryptionError (subclass of WorkflowRuntimeError) that the encryption module throws when subtle.encrypt/subtle.decrypt fails, with the original DOMException as cause plus diagnostic context (operation, byteLength, printable/hex format prefix of the input header). classifyRunError now picks it up via RUNTIME_ERROR_CHECKS, so these failures surface as RUNTIME_ERROR with a proper named class for dashboards and triage. * Trim changeset description to one sentence * Trim historical-context comments * docs: add runtime-decryption-failed troubleshooting page (v4 + v5) * fix(core): round-trip RuntimeDecryptionError context, fix formatPrefix, propagate through serialization wrappers Addresses review feedback on #2145: - Add a RuntimeDecryptionError reducer/reviver (+ SerializableSpecial entry + globalThis registration) so its `context` (operation, byteLength, formatPrefix) survives the dehydrate/hydrate run-error round trip instead of being dropped by the generic Error reducer. - Stop capturing `formatPrefix` in the low-level encryption layer, which only sees the stripped AES payload (nonce bytes), not the outer `encr` marker. The serialization layer now attaches the real envelope prefix. - Rethrow RuntimeDecryptionError unchanged from the serialize/dehydrate catch blocks instead of reframing it as a SerializationError, so an encryption failure during dehydration stays a RUNTIME_ERROR rather than being misclassified as USER_ERROR. * fix(core): enrich stream decrypt errors with envelope prefix + fix lint - Mirror the catch/enrich/rethrow block from serialization/encryption.ts around the stream-path aesGcmDecrypt() call so auth-tag failures on encrypted stream frames also carry context.formatPrefix = 'encr' (addresses review feedback). Add a tampered-frame test. - Fix all auto-fixable Biome lint findings in the touched files (template literals, useless try/catch wrappers, optional chaining, non-null assertions). |

[Docs] Fix cookbook pattern for AI SDK (#2099)
* Fix cookbook pattern for AI SDK The AI SDK cookbook entry presented `streamText` inside a `"use step"` turn function with tools also marked `"use step"`. That implies tools are individually durable, but the `"use step"` directive is a no-op when called from another step — so tools run as plain inline functions inside `runTurn`, and the durability boundary is the entire turn. Changes: - Remove the `"use step"` directive from tool implementations in the workflow code sample and add an explanatory comment. - Update the frontmatter summary and intro paragraph to drop the inaccurate "tools remain durable steps" claim. - Add a "Tools are not individually durable" entry to Pitfalls with consequences and mitigations (idempotency or `DurableAgent`). - Add a `runTurn` durability-boundary bullet to "How it works". - Add a "Tool call durability" row to the `streamText` vs `DurableAgent` comparison table. - Fix two misleading Key APIs bullets that claimed tools wrap `"use step"` functions and that `"use step"` makes tool executions durable. Applied identically to both v4 and v5 cookbook entries.

[next] make lazyDiscovery the default in withWorkflow (#1805)
* [next] make lazyDiscovery the default in withWorkflow
Flips the default for `workflows.lazyDiscovery` from `false` to `true`
so new projects get deferred workflow discovery automatically on Next.js
versions that support deferred entries (>= 16.2.0-canary.48). Older
versions continue to fall back to eager discovery.
Users can still opt back into eager discovery explicitly by passing
`workflows: { lazyDiscovery: false }`.
Also:
- Remove the now-redundant `lazyDiscovery: true` from the Next.js
workbench apps.
- Reword the fallback warning for clarity when lazy is the default.
- Update the local-build e2e assertion to match the new warning text.
- Update the withWorkflow docs with the new default.
* [workbench] remove commented 'export default nextConfig' lines

fix(docs): disable Geist Mono ligatures in code blocks (#2031)
Shiki wraps each highlighted token in its own <span>, which breaks Geist Mono programming ligatures like `===`, `!==`, `=>`. The ligature glyph is rendered at the advance width of a single character (~8.4px) instead of three (~25.2px), causing it to visually overlap the preceding token. Disable `font-variant-ligatures` inside `pre code` so each character renders at its true monospace width. Co-authored-by: Claude Opus 4.7 (1M context) <noreply@anthropic.com> |

docs: split v4/v5 content trees and fix version switcher end-to-end (#1948)
* 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` Co-authored-by: Cursor <cursoragent@cursor.com> * fix(docs): use abortSignal (not signal) in DurableAgent.stream() options Co-authored-by: Cursor <cursoragent@cursor.com> * fix(docs): update prepack scripts to use versioned content paths Content moved from docs/content/docs/ to docs/content/docs/v5/ on main (pre-release channel).

feat: serializable AbortController/AbortSignal (#1301)
* 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 Co-Authored-By: Claude Opus 4.6 (1M context) <noreply@anthropic.com> * 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> * 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: 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.

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

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.

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.

Auto-remove workflow packages from serverExternalPackages (#1481)
* Warn when serverExternalPackages hides workflow-enabled packages
Add a build-time warning when packages in serverExternalPackages contain
workflow code ('use step', 'use workflow', or serialization classes).
These packages are completely invisible to the workflow compiler when
externalized, causing silent runtime failures.
The warning detects workflow patterns via two methods:
- Fast path: check package.json dependencies for @workflow/serde
- Thorough path: read the package entry file and run pattern detection
Also adds documentation in the serialization guide about the
externalization footgun for 3rd-party packages.
* Auto-remove workflow packages from serverExternalPackages
When workflow-enabled dependencies are externalized in Next.js, compiler transforms are skipped and runtime failures follow. Detect those packages in withWorkflow, remove them from serverExternalPackages for the current build, and keep a generalized externalPackages warning fallback for non-Next builders.
* Address review feedback: add entry-point limitation comment and missing test case

Serialize run_failed/step_failed errors through serialization pipeline (#1851)
* 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.
