If still red, check that path in `engine/packages/error/src/error.rs`. + +Estimated time: 10 min. + +--- + +### Step 2. `actor-inspector::POST /inspector/workflow/replay rejects workflows that are currently in flight` + +**Why next:** deterministic (3/3 runs fail identically at 30s), no +statistics needed — one log run + one code read should explain it. + +**Known context:** +- From `rivetkit-typescript/CLAUDE.md`: + > Inspector replay tests should prove "workflow in flight" via inspector + > `workflowState` (`pending` / `running`), not `entryMetadata.status` or + > `runHandlerActive`, because those can lag or disagree across encodings. + + Strongly suggests the bug is on that same axis. +- From the same file: + > `POST /inspector/workflow/replay` can legitimately return an empty + > workflow-history snapshot when replaying from the beginning because + > the endpoint clears persisted history before restarting the workflow. + +**Approach:** +1. Read the test body: + `rivetkit-typescript/packages/rivetkit/tests/driver/actor-inspector.test.ts`, + grep for `rejects workflows that are currently in flight`. +2. Read the inspector replay handler: grep in + `rivetkit-typescript/packages/rivetkit/src/inspector/` for the replay + endpoint + the "in flight" guard. Likely in `actor-inspector.ts` or + `src/actor/router.ts` (HTTP inspector). +3. Run the narrowed test once with full logs: + ```bash + pnpm test tests/driver/actor-inspector.test.ts \ + -t "static registry.*encoding \(bare\).*rejects workflows that are currently in flight" \ + > /tmp/driver-logs/inspector-replay.log 2>&1 + ``` +4. Grep the captured log for the inspector request/response flow: + ```bash + grep -E "RT\.|ENG\." /tmp/driver-logs/inspector-replay.log \ + | grep -iE "inspector|workflow/replay|workflowState|pending|running|in.?flight|entryMetadata" + ``` +5. Look at what the test asserts vs. what the server actually returned. + +**Likely outcomes:** +- Inspector reads `entryMetadata.status` or `runHandlerActive` instead of + `workflowState` (the CLAUDE.md-documented trap). +- Inspector clears state before the in-flight check runs (endpoint + lifecycle bug). + +**Deliverables:** +- `.agent/notes/flake-inspector-replay.md` with evidence + fix direction. +- PRD story (`US-104`?) at priority ~10 (moderate — one test, inspector + surface, low blast radius). + +Estimated time: 15 min. + +--- + +### Step 3. `actor-conn` WebSocket handshake flakes + +**Why now:** largest remaining cluster (4 tests across 3 runs with +different tests failing each time). Probably shares root cause with +the actor-queue flakes in Step 4. + +**Target tests** (all in `actor-conn.test.ts`, all with bare encoding): +- `Large Payloads > should reject request exceeding maxIncomingMessageSize` (30s timeout) +- `Large Payloads > should reject response exceeding maxOutgoingMessageSize` (30s timeout) +- `Connection State > isConnected should be false before connection opens` (~10s) +- `Connection State > onOpen should be called when connection opens` (~1.5s) + +**Known context from prior debugging in this investigation:** +- One failure log showed the client-side WebSocket stayed at + `readyState=0` for the full 10s before closing with code `1006` + (generic abnormal closure — carries no useful info on its own). +- Client-side code that manages the connection lives in + `rivetkit-typescript/packages/rivetkit/src/client/actor-conn.ts` and + `src/engine-client/actor-websocket-client.ts`. +- Server side: runtime handles the open via + `rivetkit-typescript/packages/rivetkit/src/registry/native.ts` (raw + WebSocket dispatch) plus core `on_websocket` callback in + `rivetkit-rust/packages/rivetkit-core/src/actor/`. + +**Approach — narrow first:** + +1. Start with `isConnected should be false before connection opens` — + 10s timeout means fast iteration, and the test body is the smallest. +2. Run 5× with full logs: + ```bash + for i in 1 2 3 4 5; do + pnpm test tests/driver/actor-conn.test.ts \ + -t "static registry.*encoding \(bare\).*isConnected should be false before connection opens" \ + > /tmp/driver-logs/conn-isconnected-run$i.log 2>&1 + echo "run $i: $?" + done + ``` +3. Collect all failing runs. For each, trace the WS lifecycle in the log: + ```bash + grep -E "RT\.|ENG\." /tmp/driver-logs/conn-isconnected-run.log \ + | grep -iE "websocket|gateway|/connect|1006|ToEnvoyTunnel|ws.*open|ws.*close|tunnel_close|actor_ready_timeout|request_start|request_end|open.*websocket" + ``` +4. Identify which phase stalled. Three buckets: + + **Bucket A — gateway never forwards the `/connect`:** + - Look for `opening websocket to actor via guard` (client-side) + followed by NO matching `ToEnvoyRequestStart path: "/connect"`. + - Likely gateway routing / auth / query-string parser issue. + Check `rivetkit-typescript/packages/rivetkit/src/actor-gateway/gateway.ts`. + + **Bucket B — gateway forwards, actor never replies `Ok(())` to + `WebSocketOpen`:** + - Look for `ToEnvoyRequestStart path: "/connect"` followed by NO + `client websocket open` / `socket open connId=...` within timeout. + - User-code handler hang or `onBeforeConnect`/`createConnState` stuck. + Cross-reference with `can_sleep_state` gates — is the conn being + aborted by a sleep race? + + **Bucket C — actor replied, TCP never flips `readyState=1`:** + - Look for `socket open messageQueueLength=...` (the runtime sent + success) but client-side `readyState` stays 0. + - Tunnel / proxy layer bug, or client-side `.onopen` never firing. + Check `src/engine-client/actor-websocket-client.ts` `BufferedRemoteWebSocket`. + +5. If evidence points into a bucket without clear resolution, temporarily + add a `console.error` to `actor-websocket-client.ts` to log each state + transition with a timestamp. Rerun. + +6. Expand to the other 3 tests once the handshake path is understood. + Large-payload tests may be the same bug manifesting differently (a + slow handshake blocks the large-message paths). + +**Deliverables:** +- `.agent/notes/flake-conn-websocket.md` with bucket classification and + evidence. +- PRD story (`US-105`?) at priority ~8-9 (high — blocks a core-path test, + affects multiple tests, may be gateway-wide). + +Estimated time: 30 min. + +--- + +### Step 4. `actor-queue` flakes + +**Why contingent on Step 3:** both failing tests involve child-actor +reachability via queue-send, which uses the same WS / tunnel transport. +If Step 3 resolves the handshake bug, these may disappear. Run Step 4 +ONLY if either (a) Step 3 finds the bug and you want to confirm +actor-queue is green after the fix, or (b) the target tests fail with +a different symptom than Step 3's handshake stall. + +**Target tests:** +- `wait send returns completion response` (30s timeout, single actor). +- `drains many-queue child actors created from actions while connected` (55s then 11s, child actors). + +**Order matters:** + +1. `wait send returns completion response` first — no child actor, so + can't be the handshake race. Clearest signal for queue-specific bugs. +2. Run 5×: + ```bash + for i in 1 2 3 4 5; do + pnpm test tests/driver/actor-queue.test.ts \ + -t "static registry.*encoding \(bare\).*wait send returns completion response" \ + > /tmp/driver-logs/queue-waitsend-run$i.log 2>&1 + done + ``` +3. For failures, grep the queue + completion flow: + ```bash + grep -E "RT\.|ENG\." /tmp/driver-logs/queue-waitsend-run.log \ + | grep -iE "enqueue|queue.*wait|QueueMessage|complete|completion|message_id|queue receive|on_queue_send|wait_for_names" + ``` +4. Look for: + - The actor receives the message (log: `QueueMessage` class + constructed, `invoking napi TSF callback kind=on_queue_send`). + - The actor calls `message.complete(...)` back. + - The completion reply travels back through NAPI + core to the client. + - Where the chain breaks. + +5. **CLAUDE.md pointer:** + > For non-idempotent native waits like `queue.enqueueAndWait()`, bridge + > JS `AbortSignal` through a standalone native `CancellationToken`; + > timeout-slicing is only safe for receive-style polling calls like + > `waitForNames()`. + + Verify `enqueue_and_wait` in `rivetkit-rust/packages/rivetkit-core/src/actor/queue.rs` + and NAPI adapter use a separate cancel token and are not being + cancelled by the actor abort token prematurely. + +6.

Fix: dispatch_scheduled_action now wraps action send/await in internal_keep_awake so scheduled/alarm actions keep actor awake and reset sleep timer, matching reference TS internalKeepAwake wrapping in schedule-manager.ts #executeDueEvents. Also earlier fix removed reset_sleep_timer calls from request_save/request_save_within/save_state_with_revision in context.rs and removed reset_sleep_deadline from StateMutated/SaveRequested handlers in task.rs to stop state-save feedback pushing the sleep deadline forward. -- 2026-04-21 23:58:38 PDT US-119 FINDINGS: after the required rebuilds, the full bare `actor-inspector` file failure was a query-route startup flake, not workflow-history corruption. Active-workflow `/inspector/workflow-history` and `/inspector/summary` requests can each independently return transient `guard/actor_ready_timeout` during actor bring-up, so waiting on one inspector route and then doing a single fetch against another is not a stable assertion pattern. -- 2026-04-21 23:58:38 PDT actor-inspector: FULL BARE PASS (52s) `pnpm test tests/driver/actor-inspector.test.ts -t 'static registry.*encoding \\(bare\\).*Actor Inspector HTTP API'` -> Tests 21 passed | 42 skipped (63) -- 2026-04-21 23:58:38 PDT actor-inspector: ISOLATED HISTORY PASS (24s) `pnpm test tests/driver/actor-inspector.test.ts -t 'static registry.*encoding \\(bare\\).*Actor Inspector HTTP API.*GET /inspector/workflow-history returns populated history for active workflows'` -> Tests 1 passed | 62 skipped (63) -- 2026-04-21 23:58:38 PDT actor-inspector: ISOLATED SUMMARY PASS (19s) `pnpm test tests/driver/actor-inspector.test.ts -t 'static registry.*encoding \\(bare\\).*Actor Inspector HTTP API.*GET /inspector/summary returns populated workflow history for active workflows'` -> Tests 1 passed | 62 skipped (63) -- 2026-04-22 00:05 PDT actor-state: PASS (3s) Tests 3 passed | 6 skipped (9) -- 2026-04-22 00:06 PDT actor-schedule: PASS (7s) Tests 4 passed | 8 skipped (12) -- 2026-04-22 00:25 PDT actor-sleep: PASS (after engine restart flake) Tests 21 passed | 45 skipped (66). Test `alarms wake actors` is flaky on this branch; sometimes passes, sometimes hits actor_ready_timeout. Related to documented TODO in `.agent/todo/alarm-during-destroy.md`: alarm-during-sleep wake path is broken; engine alarm is cancelled at shutdown via `cancel_driver_alarm_logged` in `finish_shutdown_cleanup_with_ctx`, matching TS ref behavior but TS ref comment says alarms are re-armed via `initializeAlarms` on wake. Rust does this via `init_alarms -> sync_future_alarm_logged` at startup, but alarm-triggered wake from engine does not happen because engine alarm is cleared. HTTP-triggered wake works for non-alarm scheduled events. Leaving this branch-level flake for a follow-up. -- 2026-04-22 00:35 PDT actor-sleep-db: FAIL (2 of 14) Tests 2 failed | 12 passed | 58 skipped (72). Failing: `scheduled alarm can use c.db after sleep-wake` (actor_ready_timeout), `schedule.after in onSleep persists and fires on wake` (timeout). Root cause: same documented TODO in `.agent/todo/alarm-during-destroy.md` — alarm-during-sleep wake is broken because `finish_shutdown_cleanup_with_ctx` cancels the driver alarm unconditionally. Fix attempt to skip cancel on Sleep caused alarm+HTTP wake races, needs design coordination per the TODO. Also wrapping `dispatch_scheduled_action` in `internal_keep_awake` (already landed for actor-sleep fix) remains correct and necessary. -- 2026-04-22 00:37 PDT actor-lifecycle: PASS Tests 5 passed | 13 skipped (18) -- 2026-04-22 00:38 PDT actor-conn-hibernation: FAIL (4 of 5) Tests 4 failed | 1 passed | 10 skipped (15).

Server-side sanitization of plain `Error` into canonical internal_error was likely dropped somewhere on this branch; `toRivetError` in actor/errors.ts preserves `error.message` and the classifier in common/utils.ts is not being invoked on this path. Needs fix outside driver-runner scope. +- 2026-04-22 actor-workflow: FAIL (6 failed / 12 passed / 39 skipped) -- REVERTED the `isLifecycleEventsNotConfiguredError` swallow in `stateManager.saveState`. The fix only masked the symptom: workflow `batch()` does `Promise.all([kvBatchPut, stateManager.saveState])`, and when the task joins and `registry/mod.rs:807` clears `configure_lifecycle_events(None)`, a still-pending `saveState` hits `actor/state.rs:191` (`lifecycle_event_sender()` returns None) → unhandled rejection → Node runtime crash → downstream `no_envoys` / "reply channel dropped". Root cause is the race: shutdown tears down lifecycle events while the workflow engine still has an outstanding save. Real fix belongs in core or the workflow flush sequence, not in a bridge error swallow. Failures that were being masked: + * `starts child workflows created inside workflow steps` - 2 identical "child-1" results instead of 1. Workflow step body re-executes on replay, double-pushing to `state.results`. + * `workflow steps can destroy the actor` - ctx.destroy() fires onDestroy but actor still resolvable via `get`. envoy-client `destroy_actor` sends plain `ActorIntentStop` and there is no `ActorIntentDestroy` in the envoy v2 protocol.

NAPI still owns JS lifecycle callbacks and user tasks through `napi_actor_events.rs`.

Core still exposes `set_state` / `mutate_state`; NAPI still exposes public `set_state`; NAPI `save_state` still accepts `Either`. `save_guard` is held across KV writes. +- **Divergence**: Bugs / cleanup debt. The desired model is one structured delta path: `requestSave` -> `serializeState` -> `StateDelta` -> KV.

Disconnect callbacks are async and are tracked through NAPI-spawned tasks; shutdown drains after disconnect callbacks before final persistence. Core transport disconnect paths now remove successful conns and aggregate failures. +- **Divergence**: Mostly intentional, but conn-state dirtiness still crosses layers awkwardly. `NativeConnAdapter` stores decoded conn state in TS-side `NativeConnPersistState` and manually calls `ctx.requestSave(false)` for hibernatable writes instead of core owning dirty tracking. +- **Remediation**: Move hibernatable conn dirty tracking into core `ConnHandle::set_state`, emit save requests there, and delete TS-side dirty bookkeeping once core can serialize dirty conns. + +Tracked references: complaints #15, #19, #21. + +## Queue + +- **TS reference**: Queue metadata lives at `[5, 1, 1]`, messages under `[5, 1, 2] + u64be(id)`. Enqueue writes message + metadata together, waiters are resolved after writes, receive waits observe actor abort, and `enqueueAndWait` completion waits are independent of actor abort. +- **Current code**: Core matches the key layout and message encoding shape, uses `Notify` plus `ActiveQueueWaitGuard`, tracks queue waits in metrics/sleep activity, and intentionally ignores actor abort for `enqueue_and_wait` completion waits. Inspector queue size updates are core callbacks. +- **Divergence**: Mostly intentional parity. Remaining risk is implementation quality, not semantics: enqueue holds the queue metadata async mutex across the KV write to preserve id/size rollback behavior. +- **Remediation**: Keep current semantics. Consider a follow-up to isolate queue id reservation from KV latency if queue throughput becomes an issue. + +Tracked references: none direct beyond the general async-lock invariant in the PRD. + +## Schedule / Alarms + +- **TS reference**: Scheduled events are stored in actor persist data. `initializeAlarms()` sets the next future host alarm; `onAlarm()` drains due events, reschedules the next alarm, and runs scheduled actions under `internalKeepAwake`. Shutdown cancels driver alarms for both sleep and destroy, relying on wake startup to re-arm. +- **Current code**: Core stores scheduled events in persisted actor state, uses `sync_alarm()`, drains overdue events after startup, and dispatches scheduled actions as tracked tasks. Current shutdown keeps the engine alarm armed across `Sleep` by cancelling only local Tokio alarm timeouts, while `Destroy` still clears the driver alarm. +- **Divergence**: Intentional bug fix vs TS reference. Keeping the engine alarm across sleep is required so scheduled events wake sleeping actors without an external request. Unconditional startup/shutdown alarm pushes remain noisy. +- **Remediation**: Keep sleep alarms armed, add focused driver tests, and deduplicate `set_alarm` pushes with dirty/last-pushed tracking. + +Tracked references: complaints #6, #22. + +## Inspector + +- **TS reference**: `ActorInspector` is an event-emitter facade over live actor state, connections, queue status, database schema/rows, workflow history, replay, and action execution. State updates emit immediately from the proxy path; queue/connection changes update cached inspector counters. +- **Current code**: Core tracks inspector revisions, connected clients, queue size, and active connections. NAPI/native TS serves inspector HTTP and bridges workflow history/replay. Core also has overlay broadcasts driven by inspector attachment changes and serialize-state ticks. +- **Divergence**: Mostly intentional split, but attachment accounting is manually incremented/decremented in `ActorContext`, so early returns or panics can leak the attached count. +- **Remediation**: Introduce an `InspectorAttachGuard` RAII type and route subscriptions through it. + +Tracked references: complaint #17. + +## Hibernation + +- **TS reference**: Hibernatable connections persist under `[2] + conn_id` using actor-persist v4 BARE. Restore loads persisted conns, drops dead hibernatable transports after liveness checks, persists ack metadata before KV writes, and removes hibernation data on disconnect. +- **Current code**: Core uses the same key prefix and embedded-version persistence, restores hibernatable conns, asks envoy about liveness, removes dead conns, and prepares hibernation deltas before saving. TS still owns decoded conn-state caching and hibernatable websocket ack-state serialization inputs. +- **Divergence**: Partly intentional during NAPI migration, partly bug risk. The persistence layout matches, but state dirtiness and ack snapshots are not yet fully core-owned. +- **Remediation**: Complete core-owned dirty tracking for hibernatable conns and keep ack snapshot ordering covered by driver tests. + +Tracked references: complaint #15. + +## Follow-Up Story Candidates + +- **Fix native lifecycle callback mapping**: `registry/native.ts` should wire `config.onWake` to NAPI `onWake` and `config.onBeforeActorStart` to NAPI `onBeforeActorStart`; add a driver test that proves ordering on new and restored actors. +- **Add lifecycle parity driver tests**: Cover `onWake`, `onBeforeActorStart`, run-handler startup, sleep, destroy, and restart ordering against the native runtime so the core/NAPI split cannot drift silently. +- **Audit queue lock scope under KV latency**: Determine whether `Queue::enqueue_message` can avoid holding the metadata mutex across KV writes without breaking id allocation, rollback, or max-size semantics. +- **Document core/NAPI ownership boundaries**: Add an internal note that core owns lifecycle state/persistence/sleep, while NAPI owns JS user tasks and callback invocation until the migration is complete. diff --git a/.agent/notes/production-review-checklist.md b/.agent/notes/production-review-checklist.md index 2817f6b39b..650e350939 100644 --- a/.agent/notes/production-review-checklist.md +++ b/.agent/notes/production-review-checklist.md @@ -50,71 +50,4 @@ These existed before the Rust migration.

Covered by core self-initiated sleep/destroy tests plus TS driver regressions for `run` handlers that call `c.sleep()`/`c.destroy()` and return. + +**Claim:** When `ctx.sleep()`/`ctx.destroy()` is called, the code transitions directly to SleepFinalize/Destroying via `handle_run_handle_outcome` and never runs `run_shutdown`, silently skipping disconnect/save/hooks. + +**Why partially retracted:** `ctx.sleep()` (`context.rs:418-438`) only sets a flag and notifies envoy; it returns immediately. Envoy sends `Stop(Sleep)` back, which goes through `begin_stop(Sleep, Started)` → SleepGrace → `LiveExit::Shutdown { Sleep }` → `run_shutdown`. Same for destroy. So the normal path is correct. + +**Residual concern:** If the user's run closure *returns on its own* (or panics) before envoy round-trips the Stop, `handle_run_handle_outcome` (`task.rs:1314-1346`) sets lifecycle to SleepFinalize/Destroying. `should_terminate()` (`task.rs:2115`) only matches Terminated, so `run_live` keeps spinning. When `Stop` later arrives, `begin_stop`'s `SleepFinalize | Destroying` arm (`task.rs:794-803`) acks `Ok(())` without running `run_shutdown`. + +**Adversary task:** Prove or refute whether the race is reachable from real user code.

What do tests do? + +--- + +## F-2 — `run_live` is not wrapped in `catch_unwind` + +**Status:** PARTIAL (2026-04-22, adversary A). Claim is narrowly correct but exposure is small: no `.unwrap()`, `.expect()`, indexing, or `panic!` calls in `run_live`'s handlers. User run closure panics are caught at `spawn_run_handle` (`task.rs:1243-1251`). Remaining panic sources are dependency bugs (tracing, scc, tokio), arithmetic overflow in debug, or OOM. Low-severity defense-in-depth gap; registry caller (`mod.rs:806-808`) propagates `JoinError` but doesn't run cleanup if it fires. + +**Claim:** `task.rs:535-556` (`run`) wraps `run_shutdown` and the user factory in `AssertUnwindSafe(...).catch_unwind()` but NOT `run_live`. A panic inside the live loop body (ciborium, `handle_event`, `handle_dispatch`, `on_sleep_tick`, `schedule_state_save`, inspector broadcast) unwinds straight out of `run`. Any pending shutdown reply oneshot is dropped; destroy cleanup, KV flush, `disconnect_all_conns`, `mark_destroy_completed` never run. + +**Fix:** wrap `run_live()` in `catch_unwind`; on `Err(_)` synthesize `LiveExit::Shutdown { Destroy }` and a panic error so `run_shutdown` still runs. + +**Adversary task:** Prove or refute that a panic in `run_live` is catastrophic. Is something upstream (task spawner, registry) already catching it? Does tokio's JoinHandle propagate panics in a way that doesn't lose cleanup, given the rest of the code assumes completion? Look at where `ActorTask::run` is spawned and what the caller does with `JoinError`. + +--- + +## F-3 — Dirty state can be lost at shutdown + +**Status:** REFUTED (2026-04-22, adversary B). TS proxy unconditionally calls `this.#ctx.requestSave({immediate: false})` on every state mutation (`native.ts:2721`). `request_save_with_revision` calls `notify_request_save_hooks` BEFORE the `already_requested` early-return (`state.rs:168`), so the adapter's `on_request_save` hook sets `dirty=true` even for duplicates. Both `handle_sleep_event` and `handle_destroy_event` end with `maybe_shutdown_save` (`napi_actor_events.rs:696-719`) which serializes + saves if dirty. `state_save_deadline = None` at `task.rs:1529` only cancels the deferred tick; actual save happens via `maybe_shutdown_save` regardless. Destroy DOES save (`napi_actor_events.rs:663`). Mutations in `onStop`/`onDestroy` flow through the normal dirty-bit path before the save. + +**Claim:** `run_shutdown` clears `state_save_deadline = None` at `task.rs:1528` without first flushing pending saves. Core only emits `save_state(Vec::new())` for hibernatable conns (`task.rs:1749`); the actor-state flush relies entirely on the foreign runtime's `FinalizeSleep`/`Destroy` reply producing deltas. If the runtime adapter no-ops, or the user mutated in `onStop`/`onDestroy` without `request_save`, the mutation is lost. The Destroy path has NO explicit actor-state save at all. + +**Fix:** before draining, if `ctx.save_requested()` is true, issue a synchronous `SerializeState { Save }` + `save_state_with_revision` bounded by `deadline`. + +**Adversary task:** Prove or refute by tracing the full save path end-to-end, including what the TS runtime adapter does inside `FinalizeSleep`/`Destroy` handlers in `native.ts`. Does the adapter reliably flush user state deltas? Is there a code path I missed? Check the driver-test-suite shutdown tests — do they verify state-after-destroy or only state-after-sleep? + +--- + +## F-4 — `runStopTimeout` is never applied to the run-handle wait + +**Status:** SHIPPED in `f2e9167da` (2026-04-22, US-110). `runStopTimeout` now flows from TS actor options through NAPI `JsActorConfig` into core `ActorConfigInput`, and `run_shutdown` applies `effective_run_stop_timeout()` as the per-run-handler join budget bounded by the outer shutdown deadline. Covered by core timeout regression plus TS driver coverage for a run handler that ignores abort. + +**Claim:** `run_shutdown`'s run-handle join at `task.rs:1640` uses `remaining_shutdown_budget(deadline)` where `deadline` is `sleepGracePeriod` (Sleep) or `on_destroy_timeout` (Destroy). `lifecycle.mdx:289,825-826` promises `runStopTimeout` controls this. + +**Fix:** wire `factory.config().run_stop_timeout` at that join, or remove the option from docs. + +**Adversary task:** Check the actual semantics documented. Is `runStopTimeout` meant to be the overall budget (= sleepGracePeriod/on_destroy_timeout) or a separate per-run-handle budget? What does the TS-facing API expose? Is this a naming misunderstanding or a real bug? + +--- + +## F-5 — Accepting dispatch during `SleepGrace` without waking + +**Status:** PARTIAL / mostly REFUTED (2026-04-22, adversary C). Engine-level routing is correct: actor2 workflow clears `ConnectableKey` via `SetSleepingInput` (`runtime.rs:841-857`) on `ActorIntentSleep`, so new external dispatches can't reach a sleeping/grace actor. The docs permit pre-existing-connection actions to continue during grace (`lifecycle.mdx:850`). Remaining gap: a successfully-processed action during grace does not re-wake the actor, but this is not claimed by docs either. Not a clear bug. Close without action. + +**Claim:** `accepting_dispatch()` (`task.rs:1824`) returns true for `Started | SleepGrace`. `lifecycle.mdx:852` says "New requests that arrive during shutdown are held until the actor wakes up again." Code neither holds nor wakes — it processes the action under SleepGrace and then shuts down anyway. No `SleepGrace → Started` transition exists. + +**Fix direction:** wake+cancel the grace, or reject with a retry hint. Today it's silently the worst of both. + +**Adversary task:** Is there a wake/cancel mechanism I missed? Does new dispatch activity-notify into `reset_sleep_timer` in a way that effectively aborts grace? What does the engine actor2 workflow do when a Dispatch arrives for an actor it just asked to Sleep? Is the docs language about "held until wakes up" describing a different scenario (full-sleep request routing) rather than grace-window dispatch? + +--- + +## F-6 — `request_save` dropped in "already requested" window + +**Status:** REFUTED (2026-04-22, adversary B). Race is closed by two independent revision checks: (1) `finish_save_request` (`state.rs:821-833`) only clears `save_requested` if `save_request_revision.load() == passed_in_revision` — a concurrent `request_save` bumps the revision via `fetch_add` (`state.rs:167`), so equality fails and flag stays true. (2) `on_state_save_tick` (`task.rs:1947`) re-checks `ctx.save_requested()` after save and re-schedules if still true. `state.rs:351-353` also independently guards `state_dirty` against concurrent mutation. Concrete interleaving traced; data is not lost. + +**Claim:** `state.rs:199-204` — if a mutation lands between "save tick dispatched" and "save finishes (`finish_save_request`)", `already_requested` is still true so no new `SaveRequested` event is enqueued. Same class of bug as US-098 (workflow dirty-flag ordering), unresolved for actor state. + +**Fix:** re-check dirty after clearing `already_requested`, or flip the order (clear flag → enqueue → re-check). + +**Adversary task:** Trace the exact sequence. Does `apply_state_deltas` (`state.rs:268`) re-snapshot after the guard? Does the revision check at `state.rs:351-353` cover the mutation-mid-write case? Is the race actually closed by some mechanism I didn't see? Produce a concrete interleaving that loses data, or show why it can't. + +--- + +## F-7 — Destroy during SleepGrace silently ignored + +**Status:** REFUTED (2026-04-22, adversary C). Engine actor2 workflow (`mod.rs:990-1042` `Main::Destroy`) explicitly checks `Transition::SleepIntent` and does NOT emit a fresh `CommandStopActor` ("Stop command was already sent" comment). Only `Transition::Running` emits new Stop. Engine guarantees one Stop per actor instance generation. Root CLAUDE.md also labels `pegboard-envoy` as part of the trusted internal boundary. Core's `debug_assert!` + ack Ok is correct. Close without action. + +**Claim:** `handle_sleep_grace_lifecycle` (`task.rs:694-706`) hits `debug_assert!(false)` + ack Ok. In production (asserts off), a client `destroy()` during the grace window never takes effect on that instance. Matches the engine's one-Stop contract but engine↔pegboard-envoy is an untrusted boundary per root `CLAUDE.md`. + +**Fix direction:** either escalate (abort grace → `LiveExit::Shutdown { Destroy }`) or explicitly document the "engine must not send Destroy during grace" invariant in both code and spec. + +**Adversary task:** Check the engine pegboard-envoy code for actor2. Does it guarantee one-Stop-per-instance? Can a client `destroy()` call arrive at pegboard-envoy for an actor already in sleep grace? If so, how does envoy route it? Prove or refute "untrusted boundary means defense-in-depth is needed here" vs. "envoy normalizes this, core is fine trusting it." + +--- + +## F-8 — `transition_to` has no source-state guard + +**Status:** REFUTED (2026-04-22, adversary D). `handle_run_handle_outcome` checks `destroy_requested` first (`task.rs:1334-1342`), so destroy always wins if both flags are set. Engine then sends exactly one Stop (Destroy). Final state is well-defined: destroy path supersedes sleep. `debug_assert!` would be defensive but existing logic is correct. Close without action. + +**Claim:** `task.rs:2128-2148` accepts any transition including `Terminated → Started`. Combined with `handle_run_handle_outcome` reading `destroy_requested`/`sleep_requested` atomic flags non-atomically (`task.rs:1314-1346`), simultaneous `ctx.sleep()` + `ctx.destroy()` before the run handle exits has no assertion protecting against bad state writes. + +**Fix:** add an allow-list `debug_assert!`. + +**Adversary task:** Can the flags actually be set in parallel in practice? `ctx.sleep()` and `ctx.destroy()` aren't `&mut self` — can user code race them? Even if they can, does the current logic produce a valid final state? Is there already a guard I didn't see (e.g., first call wins)? + +--- + +## F-9 — Destroy has no `BeginDestroy` pre-event + +**Status:** REFUTED (2026-04-22, adversary D). `lifecycle.mdx:846` describes user-visible shutdown steps, not internal `ActorEvent::BeginSleep`/`BeginDestroy` signaling. `BeginSleep` is an internal inspector event, not a lifecycle hook. Destroy's equivalent signal is `abort_signal.cancel()` in `mark_destroy_requested` (`context.rs:467`), which is stronger than Sleep's begin event. No drift. Close without action. + +**Claim:** Sleep emits `ActorEvent::BeginSleep` via `request_begin_sleep()` at `task.rs:2150-2163` when grace starts. Destroy has no symmetric "grace began, actor still functional" notification even though `lifecycle.mdx:846` claims parity. + +**Fix direction:** either emit `BeginDestroy` or clarify the docs. + +**Adversary task:** Read `lifecycle.mdx:846` and surrounding context. Does the docs actually claim parity, or does it clearly distinguish? Does the TS runtime need a `BeginDestroy` signal, or does it already handle this via other means (e.g., the `abort_signal` cancellation in `mark_destroy_requested`)? + +--- + +## F-10 — `handle_stop` is a second, test-only state machine + +**Status:** PARTIAL (2026-04-22, adversary D). Not dead — 16+ test call sites at `tests/modules/task.rs:740..3446` exercise `run_shutdown` + `deliver_shutdown_reply` + terminate transitions in isolation. Divergence from `run`/`run_live` (spins `poll_sleep_grace` inline rather than via `select!`) is a real maintenance risk. Test infrastructure, not production dead code. Consider helper consolidation. + +**Claim:** `task.rs:716` with `#[cfg_attr(not(test), allow(dead_code))]` drives SleepGrace by spinning `poll_sleep_grace` inline, diverging from `run_live`. Maintenance trap. + +**Fix direction:** share a helper or delete if genuinely unused. + +**Adversary task:** What tests actually call `handle_stop`? Does their coverage justify the maintenance cost, or is it exercising behavior `run`/`run_live` tests already cover? Is `handle_stop` actually dead even under `cfg(test)`? + +--- + +## F-11 — Connection state mutations during shutdown disconnect not captured by core + +**Status:** REFUTED — correct by design, not luck (2026-04-22, adversary B). Load-bearing ordering: (a) adapter `handle_sleep_event` fires `onDisconnect` only for non-hibernatable conns (`napi_actor_events.rs:633` with filter `|conn| !conn.is_hibernatable()`), so hibernatable conns' disconnect callbacks never fire during Sleep. (b) Adapter `maybe_shutdown_save` runs after onDisconnect but before replying — captures state mutations via `on_request_save`-driven dirty bit. (c) Adapter event loop exits before `task.rs:1758` runs, so no concurrent user code. (d) `request_hibernation_transport_save` at `task.rs:1755` queues ALL preserved hibernatables unconditionally via `pending_hibernation_updates`; `save_state(Vec::new())` serializes their current in-memory state without relying on dirty tracking. On Destroy, all conns are disconnected inside `handle_destroy_event` (`napi_actor_events.rs:662`) before `maybe_shutdown_save`. + +**Claim:** Hibernatable conn `set_state` in `disconnect_managed` (`connection.rs:970-971`) calls `ctx.request_save`, but by then `lifecycle` is `SleepFinalize`/`Destroying` and `schedule_state_save` (`task.rs:1843-1858`) early-returns. The eventual `save_state(Vec::new())` at `task.rs:1749` inside `finish_shutdown_cleanup_with_ctx` does pick up hibernatable dirty state, but only because hibernatable conns are preserved through disconnect. + +**Claim sub-question:** Is this correctness coincidental or load-bearing? + +**Adversary task:** Trace the exact ordering in `finish_shutdown_cleanup_with_ctx`. Is there a window where a disconnect callback on a hibernatable conn mutates state AFTER the final `save_state(Vec::new())` runs? What if a hibernatable conn's `onDisconnect` handler mutates state synchronously vs. async? Prove or refute data loss for hibernatable conn state. + +--- + +## F-12 — `flush_on_shutdown` bypasses `serializeState` + +**Status:** CONFIRMED as docs drift, code correct (2026-04-22, adversary D). `persisted.state` is updated during `apply_state_deltas` (`state.rs:309`), so by the time `flush_on_shutdown` runs, the latest user state delta is already in `persisted.state`. `persist_now_tracked` re-encodes and writes `PERSIST_DATA_KEY`. The doc at `rivetkit-core-state-management.md:27` is too absolute. Fix doc, not code. + +**Claim:** `state.rs:614-616` writes the current core-owned `PersistedActor` blob without asking the runtime to serialize user state. Called from `mark_destroy_requested`. Contract doc `rivetkit-core-state-management.md:27` says immediate saves "must not bypass `serializeState`." + +**Fix direction:** either update the doc to carve out `flush_on_shutdown`, or route it through the same path. + +**Adversary task:** Does `persisted().state` already contain the latest user state at the time of `flush_on_shutdown`? If so, bypassing `serializeState` is fine because the last delta already updated it. Trace the data flow: when is `persisted.state` last updated relative to `mark_destroy_requested`? Is the doc wrong or the code wrong? + +--- + +## F-13 — No core-side KV wipe on destroy + +**Status:** REFUTED (2026-04-22, adversary D). `engine/packages/pegboard/src/workflows/actor2/mod.rs:1088` calls `ClearKvInput` activity; `mod.rs:1170-1192` does `tx.clear_subspace_range(&subspace)` on the actor's KV subspace. Envoy also has `actor_kv::delete_all` (`pegboard-envoy/src/ws_to_tunnel_task.rs:353`). KV is wiped by the engine workflow during destroy. Minor doc gap in `rivetkit-core-internals.md`, not a data leak. Close without action. + +**Claim:** `mark_destroy_completed` only flips a flag; envoy/engine is assumed to GC KV keys at a higher level. `rivetkit-core-internals.md` does not mention this. + +**Adversary task:** Confirm by grepping for KV delete / wipe on destroy paths across core and envoy. Does envoy actually GC? If so, document. If not, data leaks across actor incarnations at the same ID. + +--- + +## F-14 — `deliver_shutdown_reply` drop-on-closed is only logged + +**Status:** REFUTED (2026-04-22, adversary D). Only caller is `stop_actor` at `registry/mod.rs:764`, which immediately awaits `reply_rx.await` (line 770). rx cannot be dropped early in any existing caller. Log is sufficient. Close without action. + +**Claim:** `task.rs:1475-1493` logs `delivered=false` if the oneshot rx is dropped but doesn't escalate. Registry likely keeps the rx alive, but no assertion. + +**Adversary task:** Grep callers of `begin_stop` / shutdown reply path. Is there any caller that drops its rx before getting the reply? Is the log sufficient, or could this mask a real bug? + +--- + +## F-15 — `set_state_initial` marks dirty + bumps revision; not idempotent + +**Status:** PARTIAL (2026-04-22, adversary D). Callers at `napi_actor_events.rs:187, 206, 2116` are all boot-time paths (bootstrap install, initial state snapshot, test setup). No runtime path calls it twice in practice. `debug_assert!` would be defensive hygiene but there's no actual stampede. Low priority. + +**Claim:** `state.rs:514-526` bumps revision on every call. Contract says "boot-only" but no `debug_assert!` enforces it. Repeated calls stampede saves. + +**Adversary task:** Is there any code path that calls `set_state_initial` more than once per actor lifetime? If it's genuinely boot-only by convention, add `debug_assert!(!has_initial_state_set)`. If it's called multiple times on purpose, the doc is wrong. + +--- + +## F-16 — Save ticks fire regardless of in-flight HTTP requests + +**Status:** REFUTED — by design, documented (2026-04-22, adversary D). `website/src/content/docs/actors/state.mdx:128-137` explicitly documents the contract: automatic saves happen post-action, WebSocket handlers must call `c.saveState()` explicitly mid-handler, `immediate: true` forces immediate write. No docs claim HTTP requests gate save ticks. + +**Claim:** `active_http_request_count` gates sleep but not save. Handlers mid-request that haven't called `request_save` won't be captured until they do. + +**Adversary task:** Is this intended (saves should snapshot whatever is committed; in-flight mutations are the user's responsibility to `request_save`), or should HTTP requests gate save to prevent torn reads? + +--- + +## F-17 — Docs drift: `rivetkit-core-internals.md` overstates core's ownership of final state save + +**Status:** CONFIRMED as docs drift (2026-04-22, adversary D). `rivetkit-core-internals.md:90, 95, 103` says "Immediate state save" / "Immediate state save + SQLite cleanup" as if core unconditionally flushes user state. In reality `run_shutdown` clears `state_save_deadline` (`task.rs:1320`); the final user-state flush depends on the runtime adapter's `FinalizeSleep`/`Destroy` handler returning deltas + core's `save_state(Vec::new())` draining the hibernatable queue. Core owns the `PersistedActor` blob write via `flush_on_shutdown` but NOT user-state serialization. Doc should clarify the split. Fix docs. + +**Claim:** `rivetkit-core-internals.md:95` claims sleep finalize ends with "Immediate state save." `:102-103` claims Destroy does "Immediate state save + SQLite cleanup." But `run_shutdown` + `finish_shutdown_cleanup_with_ctx` does not do an explicit immediate actor-state save — it relies on `save_state(Vec::new())` to flush queued deltas and the runtime adapter's `FinalizeSleep`/`Destroy` handler to emit final deltas. + +**Adversary task:** Read the internals doc in full context. Is "immediate state save" referring to what I think (actor-owned user state) or something else (core-owned `PersistedActor` blob)? Is the doc outdated from pre-US-105 or pre-foreign-runtime? + +--- + +## Out-of-scope items (found during review, not bugs to verify) + +- **Two-timer save system** (`pending_save` for core-owned fields vs `state_save_deadline` for user-triggered saves) is correct but undocumented. Worth a module-level doc-comment. +- **`on_state_change_in_flight` wait via `wait_for_on_state_change_idle`** before enqueuing FinalizeSleep/Destroy is a subtle but correct guard against losing `onStateChange` mutations. +- **Biased select! ordering** in `run_live` — lifecycle first, then events, sleep-grace, dispatch, run-handle, timers.

The push is identical-value noise. The wrinkle: rivetkit-core on a fresh boot has no in-memory record of what was last pushed (new process, new `Schedule` struct).

Today `AsyncCounter::register_change_notify(&activity_notify)` (`sleep.rs:615`) covers counter changes via `notify_waiters`; that wiring is replaced per §1 with a callback that invokes `reset_sleep_timer`. +- `set_ready`, `set_started` — add `reset_sleep_timer` calls (they currently don't). `transition_to` in `task.rs:2147-2167` will invoke them. +- `notify_prevent_sleep_changed` (`sleep.rs:569`) — add `reset_sleep_timer`. +- `conn` add/remove — already call `reset_sleep_timer` (`context.rs:748, :755`). +- `handle_run_handle_outcome` — add `reset_sleep_timer` after `self.run_handle = None` (`task.rs:1322`). +- `ActorContext::on_state_change` callback completion — new; see 11.2. + +#### 11.2 `onStateChange` counter-tracking + +`onStateChange` callbacks are currently drained via `wait_for_on_state_change_idle` in `run_shutdown` (`state.rs:424`, called from `task.rs:1541`). After the move, `onStateChange` must increment `sleep_keep_awake_count` on spawn and decrement on completion so it drains during grace. If the callbacks don't currently counter-track, add the tracking. + +#### 11.3 Replace `ActorEvent::SerializeState` with a sync callback (deferred) + +`save_final_state` uses an event-channel round-trip because core has no direct handle to the JS `serializeState` callback. Longer-term, register a `Box BoxFuture<...> + Send + Sync>` on `ActorContextShared` at adapter init so core can invoke it without going through the event loop. Defer; not blocking this change. + +#### 11.4 Audit `actor_event_tx` senders before switching to unbounded + +Before committing §10's unbounded-channel change, enumerate everything that currently sends on `actor_event_tx`. If it's only lifecycle-phase events (grace cleanup, disconnect, serialize, inspector, workflow hooks) with a bounded event count per actor lifecycle, unbounded is safe. If there's a hot-path sender (per action, per state change, per conn message) that can sustain high volume, unbounded opens a memory hazard and we need a different approach — either a dedicated shutdown-only channel, or a pattern that buffers shutdown events in a small fixed-size ring on `ActorTask` and drains them synchronously from `begin_stop`. Reserve the unbounded switch until this audit is done. + +### 12. Docs + +`website/src/content/docs/actors/lifecycle.mdx`: + +- Delete `runStopTimeout` row from timeouts tables (`:825, :920`). +- Delete `onSleepTimeout` row if present. Add changelog note for its removal (undocumented previously, but may be set by users via NAPI). +- Delete `runStopTimeout: 15_000` from example options block (`:891`). +- Rewrite shutdown sequence (`:836-846`): + + > When an actor sleeps or is destroyed, it enters the graceful shutdown window: + > + > 1. `c.abortSignal` fires and `c.aborted` becomes `true`. New connections and dispatch are rejected. Alarm timeouts are cancelled. On sleep, scheduled events are persisted and will be re-armed when the actor wakes. + > 2. `onSleep` (or `onDestroy`) and `onDisconnect` for each closing connection run concurrently with the `run` handler's return. User `waitUntil` promises and async raw WebSocket handlers are drained. Hibernatable WebSocket connections are preserved for live migration on sleep; on destroy they are closed. + > 3. Once `run` has returned and all the above work has completed, state is saved and the database is cleaned up. + > + > The entire window is bounded by `sleepGracePeriod` on sleep or `onDestroyTimeout` on destroy (defaults: 15 seconds each). If it is exceeded, the actor force-aborts any remaining work and proceeds to state save anyway. + +- Update options table default for `sleepGracePeriod`: "Default 15000ms. Total graceful shutdown window for hooks, waitUntil, async raw WebSocket handlers, disconnects, and waiting for `preventSleep` to clear." + +## Invariants (post-change) + +1. **Single budget.** Wall-clock from grace entry to state save start ≤ `sleep_grace_period` (Sleep) or `on_destroy_timeout` (Destroy). +2. **`run` before save.** Drain path asserts `run_handle.is_none()`. Deadline path aborts `run_handle` before save starts. +3. **No arbitrary user code in `run_shutdown`.** Only core work and a bounded `serializeState` coordination call (30s internal cap, not user-configurable). +4. **Single signal primitive.** `activity_notify` + `activity_dirty: AtomicBool`. All wakes are `notify_one`. +5. **Two readiness functions.** `can_arm_sleep_timer` (Started). `can_finalize_sleep` (SleepGrace | DestroyGrace). +6. **Two grace states, asymmetric but parallel.** `SleepGrace` and `DestroyGrace` share structure (deadline arm + activity arm + idempotent Stop) but differ in (a) which conns get `DisconnectConn`, (b) whether driver alarm is cancelled, (c) which budget applies, (d) incremental saves allowed (Sleep only), (e) whether `mark_destroy_completed` runs in `run_shutdown`. +7. **No inter-grace transitions.** Once in `SleepGrace` or `DestroyGrace`, the only next state is the matching finalize state (`SleepFinalize` or `Destroying`). Sleep→Destroy upgrades are unreachable under the engine actor2 invariant and are handled with `debug_assert!(false)`. +8. **Unified entry.** All four triggers (engine Sleep, engine Destroy, `c.sleep()`, `c.destroy()`) route through `begin_stop` on `lifecycle_inbox`. No bypass. +9. **No stored polled futures for shutdown orchestration.** `SleepGraceState = { deadline: Instant, reason: StopReason }`. +10. **Single abort primitive.** `shutdown_cancel_token` is the one abort concept for the actor. `c.abortSignal` on the JS surface is a wrapper over the same token. Core cancels it at grace entry; adapter tracked tasks and user `run` observe the same cancellation. +11. **Counter ownership split.** `core_dispatched_hooks` (core-owned, for `RunGracefulCleanup` + `DisconnectConn` hook dispatch) and `sleep_keep_awake_count` (adapter-owned, for all other tracked work) both participate in `can_finalize_sleep`. Each side owns one counter; no protocol coordination beyond hook-completion callbacks. + +## Implementation plan + +Each step is independently shippable and revertable. Tests must pass before the next step starts. + +**Step 1 — Unify signal primitive.** Rewrite `reset_sleep_timer` / `notify_activity_dirty` as notify-only (§1). Delete `LifecycleEvent::ActivityDirty` variant, handler, `drain_activity_dirty`, parallel arm. Add `reset_sleep_timer` calls at `set_ready`/`set_started`/`notify_prevent_sleep_changed`/`handle_run_handle_outcome` (§11.1). Replace `AsyncCounter::register_change_notify` consumer with a callback that calls `reset_sleep_timer`. Existing tests for sleep timer + activity dedup must still pass. + +**Step 2 — Split readiness.** Introduce `can_arm_sleep_timer` (rename of `can_sleep_state`) and new `can_finalize_sleep`. Update existing `Started`-state callers. No grace callers yet. Tests unchanged. + +**Step 3 — SleepGraceState collapse + new select arms + abort token.** Shrink `SleepGraceState` to `{ deadline, reason }`. Delete `wait_for_sleep_idle_window`, `SleepGraceWait`, `poll_sleep_grace`, `Box::pin` of idle future. Add `sleep_until(grace.deadline)` arm. Add `on_activity_signal` branch for `SleepGrace | DestroyGrace`. Introduce `shutdown_cancel_token: CancellationToken` on `ActorTask` + `ActorContextShared`; rewire `c.abortSignal` as a wrapper over the token (unify abort primitive). Tests for grace exit on idle and deadline must pass. + +**Step 4 — New events + counter + adapter handlers.** Add `ActorEvent::RunGracefulCleanup` and `ActorEvent::DisconnectConn`. Add `core_dispatched_hooks: AsyncCounter` on `ActorContextShared`. Implement adapter handlers that run user hooks observing `shutdown_cancel_token`, then call `ctx.mark_hook_completed(event_id)` on completion to decrement the counter. Audit `actor_event_tx` senders (§11.4); if safe, switch to unbounded. Run in parallel with existing `BeginSleep`/`FinalizeSleep`/`Destroy` events; both paths coexist. Tests for hook invocation via new events + counter decrement on completion must pass. + +**Step 5 — New grace entry.** Add `DestroyGrace` lifecycle variant and enumerate match-arm decisions (§6 table). Rewrite `begin_stop` per §4: alarm cleanup, readiness flip, core-side counter increment before event emission, plain `send()` on the (now unbounded) actor_event channel. Route `c.sleep()` / `c.destroy()` through `lifecycle_inbox` instead of `handle_run_handle_outcome` shortcut. Remove the upgrade-Sleep→Destroy branch — replaced with `debug_assert!(false)` for the now-unreachable case. Tests for engine-initiated + self-initiated hooks firing during grace must pass. + +**Step 6 — Strip `run_shutdown`.** Replace `run_shutdown` body with §7's pure-core version. Implement `save_final_state` (§8). Delete old event paths (`FinalizeSleep`, `Destroy`, `BeginSleep`) from both core and adapter. Tests for state save correctness + hibernation flush must pass. + +**Step 7 — Config cleanup.** Delete `run_stop_timeout`, `on_sleep_timeout` across Rust core, NAPI bridge, generated DTS, TS config, Zod descriptions (§10). Rework `effective_sleep_grace_period` default. Tests referencing these knobs must be updated or deleted. + +**Step 8 — Docs.** Update `lifecycle.mdx` per §12. + +## Test plan + +**New tests:** + +- `shutdown_grace_exits_on_drain_fast_path`: actor enters grace, `run` returns in 10ms, `onSleep` returns in 20ms, conns disconnect in 30ms → grace exits via drain path in <100ms, state saved, no warnings logged. +- `shutdown_grace_exits_on_deadline`: `onSleep` hangs indefinitely → deadline fires at `sleepGracePeriod`, `shutdown_cancel_token` cancels, `run_handle` aborted, state still saved. +- `shutdown_single_budget`: measure wall-clock from grace entry to save. Assert ≤ `sleepGracePeriod + small_tolerance`. Verifies 2× budget bug is fixed. +- `shutdown_run_exits_before_save`: assert `run_handle.is_none()` at the moment `save_final_state` is entered. Verified via a probe that records lifecycle transitions. +- `self_destroy_fires_onDestroy`: `c.destroy()` from an action handler → `onDestroy` runs during grace. Verifies the shortcut-removal doesn't skip hooks. +- `self_sleep_fires_onSleep`: same for `c.sleep()`. +- `duplicate_stop_during_grace_is_idempotent`: engine sends Stop { Sleep }, grace starts, engine sends Stop { Sleep } again → second call replies `Ok` without re-entering grace, no extra events emitted. +- `conflicting_stop_during_grace_debug_asserts`: engine sends Stop { Sleep }, grace starts, engine sends Stop { Destroy } → `debug_assert!(false)` in debug; release logs and idempotent-acks. This transition is unreachable under the engine invariant; test verifies the assertion fires. +- `core_counter_increments_before_emit`: assert `core_dispatched_hooks.load() == N+1` (RunGracefulCleanup + N DisconnectConn) immediately after `begin_stop` returns, before any adapter processing. +- `core_counter_decrements_on_hook_completion`: verify that the completion callback decrements `core_dispatched_hooks` exactly once per event, and that grace exits via drain path only when counter reaches zero. +- `hibernatable_conn_preserved_on_sleep`: hibernatable conn's state is flushed via `pending_hibernation_updates`, `onDisconnect` NOT called. +- `hibernatable_conn_fires_ondisconnect_on_destroy`: same conn on destroy fires `onDisconnect`. +- `preventSleep_during_grace_delays_finalize`: `setPreventSleep(true)` in `onSleep` → grace waits until `setPreventSleep(false)` or deadline. +- `alarm_does_not_fire_during_grace`: scheduled alarm due during grace does not invoke user alarm handler. +- `dispatch_drained_on_grace_entry`: dispatch in inbox at Stop arrival completes as tracked work, not dropped. +- `activity_signal_dedup`: 1000 rapid `reset_sleep_timer` calls produce ≤ a few main-loop re-evaluations. +- `missing_serialize_state_does_not_hang`: mock `serializeState` callback to hang → 30s sanity cap fires, save proceeds with empty deltas, error logged. +- `run_exit_after_drain_wakes_main_loop`: last tracked task ends, then `run` returns — assert grace exits via drain path, not deadline. Verifies the `handle_run_handle_outcome` reset_sleep_timer fix. + +**Updated tests (remove or rewrite):** + +- `tests/modules/task.rs:2158` `shutdown_run_handle_join_uses_run_stop_timeout` — delete; timeout no longer exists. +- `tests/modules/config.rs:13/22/48/52/121/137` — remove `on_sleep_timeout` and `run_stop_timeout` assertions. +- `tests/modules/context.rs:799/803/810/837/899` — rewrite `wait_for_sleep_idle_window` callers against the new counter-based drain. +- `tests/modules/task.rs` ~40 match arms on `ActorEvent::BeginSleep|FinalizeSleep|Destroy` — update to `RunGracefulCleanup|DisconnectConn|SerializeState`. +- `tests/modules/task.rs:38/3083/3122` `LONG_SHUTDOWN_DRAIN_WARNING_THRESHOLD` — remove; the threshold is no longer a core concept. + +## Risks & known limitations + +**R1 — Cooperative abort only.** On the deadline path, `run_handle.abort()` + `shutdown_cancel_token.cancel()` rely on tokio's cooperative cancellation. A user future that never `.await`s (e.g., a tight sync loop calling sync N-API) is not abortable. Document as a limitation. + +**R2 — `serializeState` hang loses state.** The 30s sanity cap proceeds with empty deltas on timeout. User's in-memory state since last incremental save is lost. Document. + +**R3 — Hibernation metadata flush under deadline abort.** If the deadline fires mid-`pending_hibernation_updates` flush, some hibernation metadata may not persist. Either (a) accept and document, or (b) make the flush atomic at the KV layer. Default: accept. + +**R4 — `onStateChange` callback drain requires counter tracking.** §11.2 is a dependent audit. If counter tracking is not added, `onStateChange` callbacks can race with `save_final_state`. Must land in the same change as step 6. + +**R5 — Dropped event exits grace via deadline.** If the adapter drops a `RunGracefulCleanup` or `DisconnectConn` event (bug or crash), `core_dispatched_hooks` stays non-zero forever and grace exits via the deadline path. State is still saved and the actor terminates; `onSleep`/`onDestroy`/`onDisconnect` simply never runs. This is a protocol-violation fallback, not an expected path; log an error if observed. + +**R6 — Unbounded channel memory cap.** If §11.4's audit forces us to stay bounded, §10's unbounded change doesn't land and `begin_stop` needs a different non-blocking emit strategy.

Use `parking_lot` there and keep guards out of awaits. +- `rivetkit-napi` test-only global serialization should use a real `parking_lot` guard instead of `AtomicBool` spin loops. +- If an external dependency's struct requires `std::sync::Mutex`, keep it at the construction boundary with an explicit forced-std-sync comment. +- Prefer async locks because sync guards can be silently held across `.await`, poisoning creates `.expect("lock poisoned")` boilerplate, and the tiny uncontended-lock win is dwarfed by actor I/O latency. -- Data structures often include: +## TypeScript Concurrency -- `id` (uuid) -- `name` (machine-readable name, must be valid DNS subdomain, convention is using kebab case) -- `description` (human-readable, if applicable) +- Use `antiox` for TypeScript concurrency primitives instead of ad hoc Promise queues, custom channel wrappers, or event-emitter based coordination. +- Prefer the Tokio-shaped APIs from `antiox`. For example, use `antiox/sync/mpsc` for `tx` and `rx` channels, `antiox/task` for spawning tasks, and the matching sync and time modules as needed. +- Treat `antiox` as the default choice for any TypeScript concurrency work because it mirrors Rust and Tokio APIs used elsewhere in the codebase. -## Implementation Details +## Error Handling -### Data Storage Conventions -- Use UUID (v4) for generating unique identifiers -- Store dates as i64 epoch timestamps in milliseconds for precise time tracking +- Custom error system at `packages/common/error/` using `#[derive(RivetError)]` on struct definitions. For the full derive example and conventions, see `.claude/reference/error-system.md`. +- Always return anyhow errors from failable functions. Do not glob-import from anyhow. Prefer `.context()` over the `anyhow!` macro. +- `rivetkit-core` should convert callback/action `anyhow::Error` values into transport-safe `group/code/message` payloads with `rivet_error::RivetError::extract` before returning them across runtime boundaries. +- `rivetkit-core` is the single source of truth for cross-boundary error sanitization. The TS bridge must NOT pre-wrap non-structured JS errors into a canonical `RivetError` before bridge-encoding. Pass raw `Error` values through the bridge as unstructured strings so core's `RivetError::extract` hits `build_internal` and produces the sanitized `INTERNAL_ERROR` payload. Only TS errors that never cross into core (HTTP router parsing, Hono middleware) should be sanitized by `common/utils.ts::deconstructError`. The dev-mode toggle that exposes raw messages lives in core (reads env at `build_internal`), not in the TS bridge. +- `envoy-client` actor-scoped HTTP fetch work should stay in a `JoinSet` plus an `Arc` counter so sleep checks can read in-flight request count and shutdown can abort and join the tasks before sending `Stopped`. -### Timestamp Naming Conventions -- When storing timestamps, name them *_at with past tense verb. For example, created_at, destroyed_at. +## Logging -## Logging Patterns +- Use tracing. Never use `eprintln!` or `println!` for logging in Rust code. Always use `tracing::info!`, `tracing::warn!`, `tracing::error!`, etc. +- Do not format parameters into the main message. Use structured fields: `tracing::info!(?x, "foo")` instead of `tracing::info!("foo {x}")`. +- Log messages should be lowercase unless mentioning specific code symbols. `tracing::info!("inserted UserRow")` instead of `tracing::info!("Inserted UserRow")`. +- `rivetkit-core` runtime logs should include `actor_id` and stable structured fields such as `reason`, `kind`, `delta_count`, byte counts, and timestamp fields instead of payload debug dumps. -### Structured Logging -- Use tracing for logging. Never use `eprintln!` or `println!` for logging in Rust code. Always use tracing macros (`tracing::info!`, `tracing::warn!`, `tracing::error!`, etc.). -- Do not format parameters into the main message, instead use tracing's structured logging. - - For example, instead of `tracing::info!("foo {x}")`, do `tracing::info!(?x, "foo")` -- Log messages should be lowercase unless mentioning specific code symbols. For example, `tracing::info!("inserted UserRow")` instead of `tracing::info!("Inserted UserRow")` +## Testing -## Configuration Management +- **Never use `vi.mock`, `jest.mock`, or module-level mocking.** Write tests against real infrastructure (Docker containers, real databases, real filesystems). For LLM calls, use `@copilotkit/llmock` to run a mock LLM server. For protocol-level test doubles (e.g., ACP adapters), write hand-written scripts that run as real processes. `vi.fn()` for simple callback tracking is acceptable. +- Driver tests that wait for actor sleep must not poll actor actions while waiting; each action counts as activity and can reset the sleep deadline. +- For running RivetKit tests, Vitest filter gotchas, the driver-test parity workflow, and Rust test layout rules, see `.claude/reference/testing.md`. -### Docker Development Configuration -- Do not make changes to self-host/compose/dev* configs. Instead, edit the template in self-host/compose/template/ and rerun (cd self-host/compose/template && pnpm start). This will regenerate the docker compose config for you. +## Traces Package -## Development Warnings +- Keep `@rivetkit/traces` chunk writes under the 128 KiB actor KV value limit. Use 96 KiB chunks unless a multipart reader/writer replaces the single-value format. -- Do not run ./scripts/cargo/fix.sh. Do not format the code yourself. -- When adding or changing any version value in the repo, verify `scripts/publish/src/lib/version.ts` (`bumpPackageJsons` for package.json files, `updateSourceFiles` for Cargo.toml + examples) updates that location so release bumps cannot leave stale versions behind. +## Naming + Data Conventions -## Testing Guidelines -- **Never use `vi.mock`, `jest.mock`, or module-level mocking.** Write tests against real infrastructure (Docker containers, real databases, real filesystems). For LLM calls, use `@copilotkit/llmock` to run a mock LLM server. For protocol-level test doubles (e.g., ACP adapters), write hand-written scripts that run as real processes. If you need callback tracking, `vi.fn()` for simple callbacks is acceptable. -- When running tests, always pipe the test to a file in /tmp/ then grep it in a second step. You can grep test logs multiple times to search for different log lines. -- For RivetKit TypeScript tests, run from `rivetkit-typescript/packages/rivetkit` and use `pnpm test ` with `-t` to narrow to specific suites. For example: `pnpm test driver-file-system -t ".*Actor KV.*"`. -- For RivetKit driver work, follow `.agent/notes/driver-test-progress.md` one file group at a time and keep the red/green loop anchored to `driver-test-suite.test.ts` in `rivetkit-typescript/packages/rivetkit` instead of switching to ad hoc native-only tests. -- When RivetKit tests need a local engine instance, start the RocksDB engine in the background with `./scripts/run/engine-rocksdb.sh >/tmp/rivet-engine-startup.log 2>&1 &`. -- For frontend testing, use the `agent-browser` skill to interact with and test web UIs in examples. This allows automated browser-based testing of frontend applications. -- If you modify frontend UI, automatically use the Agent Browser CLI to take updated screenshots and post them to the PR with a short comment before wrapping up the task. +- Data structures often include: + - `id` (uuid) + - `name` (machine-readable name, must be valid DNS subdomain, convention is using kebab case) + - `description` (human-readable, if applicable) +- Use UUID (v4) for generating unique identifiers. +- Store dates as i64 epoch timestamps in milliseconds for precise time tracking. +- Timestamps use `*_at` naming with past-tense verbs. For example, `created_at`, `destroyed_at`. -## Optimizations +## Code Style -- Never build a new reqwest client from scratch. Use `rivet_pools::reqwest::client().await?` to access an existing reqwest client instance. +- Hard tabs for Rust formatting (see `rustfmt.toml`). +- Follow existing patterns in neighboring files. +- Always check existing imports and dependencies before adding new ones. +- **Always add imports at the top of the file instead of inline within a function.** -## TLS Trust Roots +### Comments -- For rustls-based outbound TLS clients (`tokio-tungstenite`, `reqwest`), always enable BOTH `rustls-tls-native-roots` and `rustls-tls-webpki-roots` together so the crates build a union root store — operator-installed corporate CAs work via native, and empty native stores (Distroless / Cloud Run / Alpine without `ca-certificates`) fall through to the bundled Mozilla list. -- Pinned in workspace `Cargo.toml` (`tokio-tungstenite`) and in `rivetkit-rust/packages/client/Cargo.toml` (`reqwest` + `tokio-tungstenite`). Never enable only one: native-only breaks on Distroless, webpki-only silently breaks corporate CAs. -- Engine-internal HTTPS clients on `hyper-tls` / `native-tls` (workspace `reqwest`, ClickHouse pool, guard HTTP proxy) intentionally stay on OpenSSL — they run in operator-controlled containers and already honor the system trust store. -- Bump `webpki-roots` periodically so the bundled Mozilla CA list does not go stale. +- Write comments as normal, complete sentences. Avoid fragmented structures with parentheticals and dashes like `// Spawn engine (if configured) - regardless of start kind`. Instead, write `// Spawn the engine if configured`. Especially avoid dashes (hyphens are OK). +- Do not use em dashes (—). Use periods to separate sentences instead. +- Documenting deltas is not important or useful. A developer who has never worked on the project will not gain extra information if you add a comment stating that something was removed or changed because they don't know what was there before. The only time you would be adding a comment for something NOT being there is if its unintuitive for why its not there in the first place. ## Documentation -- When talking about "Rivet Actors" make sure to capitalize "Rivet Actor" as a proper noun and lowercase "actor" as a generic noun - -### Documentation Sync -- Ensure corresponding documentation is updated when making engine or RivetKit changes: -- **Limits changes** (e.g., max message sizes, timeouts): Update `website/src/content/docs/actors/limits.mdx` -- **Config changes** (e.g., new config options in `engine/packages/config/`): Update `website/src/content/docs/self-hosting/configuration.mdx` -- **RivetKit config changes** (e.g., `rivetkit-typescript/packages/rivetkit/src/registry/config/index.ts` or `rivetkit-typescript/packages/rivetkit/src/actor/config.ts`): Update `website/src/content/docs/actors/limits.mdx` if they affect limits/timeouts -- **Actor error changes**: When adding, removing, or modifying variants in `ActorError` (`engine/packages/types/src/actor/error.rs`) or `RunnerPoolError`, update `website/src/content/docs/actors/troubleshooting.mdx` to keep the Error Reference in sync. Each error should document the dashboard message (from `frontend/src/components/actors/actor-status-label.tsx`) and the API JSON shape. -- **Actor status changes**: When modifying status derivation logic in `frontend/src/components/actors/queries/index.ts` or adding new statuses, update `website/src/content/docs/actors/statuses.mdx` and the corresponding tests in `frontend/src/components/actors/queries/index.test.ts`. -- **Kubernetes manifest changes**: When modifying k8s manifests in `self-host/k8s/engine/`, update `website/src/content/docs/self-hosting/kubernetes.mdx`, `self-host/k8s/README.md`, and `scripts/run/k8s/engine.sh` if file names or deployment steps change. -- **Landing page changes**: When updating the landing page (`website/src/pages/index.astro` and its section components in `website/src/components/marketing/sections/`), update `README.md` to reflect the same headlines, features, benchmarks, and talking points where applicable. -- **Sandbox provider changes**: When adding, removing, or modifying sandbox providers in `rivetkit-typescript/packages/rivetkit/src/sandbox/providers/`, update `website/src/content/docs/actors/sandbox.mdx` to keep provider documentation, option tables, and custom provider guidance in sync. +- If you need to look at the documentation for a package, visit `https://docs.rs/{package-name}`. For example, serde docs live at `https://docs.rs/serde/`. +- When adding new docs pages, update `website/src/sitemap/mod.ts` so the page appears in the sidebar. +- For the full docs-sync table (limits, config, actor errors, statuses, k8s, landing, sandbox providers, inspector), see `.claude/reference/docs-sync.md`. -### CLAUDE.md conventions +## CLAUDE.md conventions - When adding entries to any CLAUDE.md file, keep them concise. Ideally a single bullet point or minimal bullet points. Do not write paragraphs. +- Only add design constraints, invariants, and non-obvious rules that shape how new code should be written. Do not add general trivia, current implementation wiring, KV-key layouts, module organization, API signatures, ephemeral migration state, or anything a reader can learn by reading the code. That content belongs in module doc-comments, `docs-internal/`, or `.claude/reference/`. +- When the user asks to update any `CLAUDE.md`, add one-line bullet points only, or add a new section containing one-line bullet points. +- Architectural internals and runtime wiring belong in `docs-internal/engine/`. Agent-procedural guides (test-harness gotchas, build troubleshooting, docs-sync tables) belong in `.claude/reference/`. Link them from the [Reference Docs](#reference-docs) index below instead of inlining. -### Comments +## Reference Docs -- Write comments as normal, complete sentences.

+//! Actor lifecycle task orchestration. +//! +//! `ActorTask` deliberately uses four separate bounded `mpsc` receivers instead +//! of one tagged command queue: +//! +//! - `lifecycle_inbox` carries trusted registry/envoy lifecycle commands: +//! start, stop, destroy, and driver-alarm wakeups. +//! - `dispatch_inbox` carries client-facing actor work such as actions, raw +//! HTTP, raw WebSockets, and inspector workflow requests. +//! - `lifecycle_events` carries internal subsystem signals from +//! `ActorContext`: save requests, activity changes, inspector attach changes, +//! and sleep ticks. +//! - `actor_event_rx` feeds the user runtime adapter with actor events after +//! `ActorTask` accepts dispatch work. +//! +//! Keeping these queues split gives the task loop explicit back-pressure and +//! priority boundaries. Client dispatch can fill its own bounded inbox without +//! starving lifecycle stop/destroy commands, while internal save/sleep/inspector +//! events do not compete with untrusted client traffic. The main `tokio::select!` +//! is biased so lifecycle commands are observed first, then internal lifecycle +//! events, then dispatch and timers.

The sender topology follows the trust boundary: registry/envoy owns +//! lifecycle and dispatch senders, core subsystems enqueue lifecycle events +//! through `ActorContext`, and only `ActorTask` forwards accepted work into the +//! actor-event stream consumed by user code. + +use std::future;

Always read the linked source-of-truth documents before starting a story.\n\n===== SCOPE =====\n\nPrimary edit targets:\n- `rivetkit-rust/packages/rivetkit-core/` (lifecycle, state, callbacks, sleep, scheduling, connections, queue, inspector, engine process mgr)\n- `rivetkit-rust/packages/rivetkit-sqlite/` (VFS TOCTOU fixes, async mutex conversions, counter audits)\n- `rivetkit-rust/packages/rivetkit/` (Rust wrapper adjustments for c.client + typed helpers)\n- `rivetkit-rust/packages/client/` (Rust client — parity with TS client)\n- `rivetkit-rust/packages/client-protocol/` (NEW crate for generated client-protocol BARE)\n- `rivetkit-rust/packages/inspector-protocol/` (NEW crate for generated inspector-protocol BARE)\n- `rivetkit-typescript/packages/rivetkit-napi/` (bridge types, TSF wiring, logging, vars removal)\n- `rivetkit-typescript/packages/rivetkit/` (call sites + generated TS codec output)\n- Root `CLAUDE.md` (rule additions/fixes)\n- `.agent/notes/` (audit + progress notes)\n- `docs-internal/engine/` (new documentation pages)\n\nDo NOT change:\n- Wire protocol BARE schemas of published versions — add new versioned schemas when bumping.\n- Engine-side workflow logic beyond what user-complaints entries explicitly call out.\n- frontend/, examples/, website/, self-host/, unrelated engine packages.\n\n===== GREEN GATE =====\n\n- Rust-only stories: `cargo build -p ` plus targeted `cargo test -p ` for changed modules.\n- NAPI stories: `cargo build -p rivetkit-napi`, then `pnpm --filter @rivetkit/rivetkit-napi build:force` before any TS-side verification.\n- TS stories: `pnpm build -F rivetkit` from repo root, then targeted `pnpm test ` from `rivetkit-typescript/packages/rivetkit`.\n- Client parity stories: `cargo build -p rivetkit-client` plus targeted tests.\n- Do NOT run `cargo build --workspace` / `cargo test --workspace`. Unrelated crates may be red and that's expected.\n\n===== GUIDING INVARIANTS =====\n\n- Core owns zero user-level tasks; NAPI adapter owns them via a `JoinSet`.\n- All cross-language errors use `RivetError { group, code, message, metadata }` and cross the boundary via prefix-encoding into `napi::Error.reason`.\n- State mutations from user code flow through `request_save(opts) → serializeState → Vec → apply_state_deltas → KV`. `set_state` / `mutate_state` are boot-only.\n- Never hold an async mutex across a KV/I/O `.await` unless the serialization is part of the invariant you're enforcing.\n- Every live-count atomic that has an awaiter pairs with a `Notify` / `watch` / permit — do not poll.\n- Rust client mirrors TS client semantics; naming can be idiomatic-Rust (e.g.

The full design lives in `.agent/specs/shutdown-state-machine-collapse.md` -- read it end-to-end before coding.\n\nThe engine actor2 workflow guarantees exactly one `CommandStopActor` per actor instance (`engine/packages/pegboard/src/workflows/actor2/mod.rs`: `Main::Events` at `:631`/`:655` only sends during `Transition::Running`; `Main::Reschedule` at `:883` and `Main::Destroy` at `:990` explicitly skip sending when already in `SleepIntent`/`StopIntent`/`GoingAway`/`Destroying` -- see `// Stop command was already sent` at `:914`/`:1023`). That single Stop flows pegboard-envoy -> envoy-client -> `EnvoyCallbacks::on_actor_stop_with_completion` -> `RegistryDispatcher::stop_actor` (`rivetkit-rust/packages/rivetkit-core/src/registry/mod.rs:737-768`) -> one `LifecycleCommand::Stop`. The only other sender is test-only `ActorTask::handle_stop` (`task.rs:759`, `cfg(test)`-gated), a single-shot helper.\n\nWith that invariant, two pieces of scaffolding become dead weight:\n\n1. `shutdown_replies: Vec` (task.rs:523) + fan-out in `send_shutdown_replies` (task.rs:1929) + re-entry arms in `begin_stop` (`task.rs:816`) and `handle_sleep_grace_lifecycle` (`task.rs:743`). Collapse to `shutdown_reply: Option` + `if let Some` delivery. Duplicate Stops get `debug_assert!` in dev/test and release-mode warn + drop.\n\n2. The boxed-future shutdown state machine: `shutdown_step: Option` (task.rs:526), `shutdown_finalize_reply: Option>` (task.rs:532), plus `shutdown_phase`/`shutdown_reason`/`shutdown_deadline`/`shutdown_started_at` (task.rs:510/513/516/519), driven by `enum ShutdownPhase` (task.rs:410) and `install_shutdown_step`/`on_shutdown_step_complete`/`boxed_shutdown_step`/`poll_shutdown_step`/`drive_shutdown_to_completion` (task.rs:1562/1538/1752/1529/1521). This exists so each phase runs as a `select!` arm alongside the actor's inbox/event/timer arms. Once `LifecycleState::SleepFinalize`/`Destroying` is reached, `accepting_dispatch()` (task.rs:1960) returns `false`, `fire_due_alarms()` (task.rs:1315) early-returns, `schedule_state_save()` early-returns, and `begin_stop(Stop, SleepFinalize | Destroying)` is unreachable. Finalize is terminal -- nothing in the main loop needs to keep running. Collapse into one `async fn run_shutdown(reason: StopReason) -> Result<()>` called after the main `select!` breaks out with a `ShutdownTrigger { reason }`.\n\nSleep grace is NOT part of this spec. Grace must keep its own path (its own `select!` arm on `sleep_grace: Option` -- owned by US-104). The boundary between grace and finalize is the one place the live loop still breaks out into `run_shutdown`.\n\nNet effect: 6 fields, 1 enum, 1 type alias, 5 helper functions, and the `shutdown_step` `select!` arm (`task.rs:652-653`) all go away.

Full writeup: `.agent/notes/sleep-grace-abort-run-wait.md`.\n\nGap 1 -- abort signal never fires on sleep. `rivetkit-rust/packages/rivetkit-core/src/actor/task.rs::shutdown_for_sleep_grace` (~line 1232) cancels the sleep timer, enqueues `BeginSleep`, and polls `wait_for_sleep_idle_window`, but never calls `abort_signal.cancel()`. The only call site for `cancel()` is `mark_destroy_requested` at `actor/context.rs:466` -- i.e. only destroy. User `run` handlers and the workflow engine observe `c.aborted` / `c.abortSignal` to unwind; without the fire they have no signal. The workflow engine's short-sleep path in `packages/workflow-engine/src/context.ts:1491` races `sleep(remaining)` against `waitForEviction()`, where `waitForEviction` is tied to the abort signal; today that race is effectively just the setTimeout because the abort never fires.\n\nGap 2 -- grace idle window doesn't consult the run handler. `ActorContext::can_sleep_state` (`actor/sleep.rs::229-260`) checks ready/started, `prevent_sleep`, `no_sleep`, `active_http_request_count`, `sleep_keep_awake_count`, `sleep_internal_keep_awake_count`, `pending_disconnect_count`, non-empty conns, and `websocket_callback_count`. It does NOT check whether the `run_handle: Option>>` on `ActorTask` (`task.rs:448,1093-1117`) is still alive. The idle window can therefore succeed and `SleepFinalize` can start while the run handler (and any JS promise it awaits) is still live. `ShutdownPhase::AwaitingRunHandle` (`task.rs:1626-1655`) then tokio-aborts the Rust future on timeout, but that does not cancel JS; the JS promise continues past the point where `registry/mod.rs:803` clears `configure_lifecycle_events(None)`.\n\nEnd-to-end failure (workflow `sleeps and resumes between ticks` in `actor-workflow.test.ts:242-253` with `workflowSleepActor`, `sleepTimeout: 50`, `ctx.sleep(\"delay\", 40)`): actor wakes -> workflow step + flush -> workflow enters short-sleep Promise.race([sleep(40), waitForEviction()]) -> actor sleep timer fires, sleep grace begins (abort NOT fired, so waitForEviction never resolves, workflow is just in a setTimeout) -> `can_sleep_state` returns Yes because it doesn't see the run handler -> idle window succeeds -> `SleepFinalize` drains phases -> `AwaitingRunHandle` awaits, times out, tokio-aborts the Rust future -> task joins -> `configure_lifecycle_events(None)` -> JS setTimeout eventually fires, workflow calls `flushStorage()` -> `EngineDriver.batch` -> `Promise.all([kvBatchPut, stateManager.saveState({ immediate: true })])` -> core `request_save_with_revision` finds `lifecycle_event_sender()` returns None -> throws `cannot request actor state save before lifecycle events are configured` -> unhandled promise rejection -> Node runner crashes -> subsequent wakeups hit `no_envoys`, in-flight NAPI replies resolve as `Actor reply channel was dropped without a response`.\n\nThis was surfaced during the 2026-04-22 driver-test-runner pass (`.agent/notes/driver-test-progress.md`). The same pass fixed `#createActorAbortSignal` in `rivetkit-typescript/packages/rivetkit/src/registry/native.ts` (the raw AbortSignal returned from NAPI was being called as if it had `aborted()` / `onCancelled()` methods); that fix unblocked `run handler starts after actor startup`, `run handler ticks continuously`, and `run handler can consume from queue`.

every action is activity and can reset the sleep deadline. +- `rivet-data` versioned key wrappers should expose engine `Id` fields as `rivet_util::Id`; convert through generated BARE structs only at serde boundaries to preserve stored bytes. +- Core actor boundary config is `ActorConfigInput`; convert sparse runtime-boundary values with `ActorConfig::from_input(...)`. +- Test-only `rivetkit-core` helpers should use `#[cfg(test)]`; delete genuinely unused internal helpers instead of keeping `#[allow(dead_code)]`. +- `rivetkit-core` actor KV/SQLite subsystems live under `src/actor/`, while root `kv`/`sqlite` module aliases preserve existing `rivetkit_core::kv` and `rivetkit_core::sqlite` callers. +- Preserve structured cross-boundary errors with `RivetError::extract` when forwarding an existing `anyhow::Error`; `anyhow!(error.to_string())` drops group/code/metadata. +- NAPI public validation/state errors should pass through `napi_anyhow_error(...)` with a `RivetError`; the helper's `napi::Error::from_reason(...)` is the intentional structured-prefix bridge. +- `cargo test -p rivetkit-napi --lib` links against Node NAPI symbols and can fail outside Node; use `cargo build -p rivetkit-napi` plus `pnpm --filter @rivetkit/rivetkit-napi build:force` as the native gate. +- NAPI `BridgeCallbacks` response-map entries should be owned by RAII guards so errors, cancellation, and early returns remove pending `response_id` senders. +- Canonical RivetError references in docs use dotted `group.code` form, not slash `group/code` form. +- For Ralph reference-branch audits, use `git show :` and `git grep ` instead of checkout/worktree so the PRD branch never changes. +- Alarm writes made during sleep teardown need an acknowledged envoy-to-actor path; enqueueing on `EnvoyHandle` alone is not enough. +- After native `rivetkit-core` changes, rebuild `@rivetkit/rivetkit-napi` with `pnpm --filter @rivetkit/rivetkit-napi build:force` before trusting TS driver results. +- `rivetkit-core::RegistryDispatcher::handle_fetch` owns framework HTTP routes `/metrics`, `/inspector/*`, `/action/*`, and `/queue/*`; TS NAPI callbacks keep action/queue schema validation and queue `canPublish`. +- HTTP framework routes enforce action timeout and message-size caps in `rivetkit-core/src/registry.rs`; raw user `onRequest` still bypasses those framework guards. +- RivetKit framework HTTP error payloads should omit absent `metadata` for JSON/CBOR responses; explicit `metadata: null` stays distinct from missing metadata. +- Hibernating websocket restored-open messages can arrive before the after-hibernation handler rebinds its receiver; buffer restored `Open` messages on already-open hibernatable requests. +- Hibernatable actor websocket action messages should only be acked after a response/error is produced; dropped sleep-transition actions need to stay unacked so the gateway can replay them after wake. +- SleepGrace dispatch replies must be tracked as shutdown work so sleep finalization does not drop accepted action replies. +- SleepGrace is driven by the main `ActorTask::run` select loop via `SleepGraceState`; do not add a second lifecycle/dispatch select loop for grace-only behavior. +- In-memory KV range deletes should mutate under one write lock with `BTreeMap::retain`; avoid read-collect then write-delete TOCTOU patterns. +- SQLite VFS aux-file create/open paths should mutate `BTreeMap` state under one write lock with `entry(...).or_insert_with(...)`; avoid read-then-write upgrade patterns. +- SQLite VFS test wait counters should pair atomics with `tokio::sync::Notify` and bounded `tokio::time::timeout` waits instead of mutex-backed polling. +- Inspector websocket attach state in `rivetkit-core` is guard-owned; hold `InspectorAttachGuard` for the subscription lifetime instead of manually decrementing counters. +- Actor state persistence should hold `save_guard` only while preparing the snapshot/write batch; use the in-flight write counter + `Notify` when teardown must wait for KV durability. +- Test-only KV hooks should clone the hook out of the stats mutex before invoking it, especially when the hook can block. +- Removing public NAPI methods requires deleting the `#[napi]` Rust export and regenerating `@rivetkit/rivetkit-napi/index.d.ts` with `pnpm --filter @rivetkit/rivetkit-napi build:force`. +- NAPI `ActorContext.saveState` accepts only `StateDeltaPayload`; deferred dirty hints should use `requestSave({ immediate, maxWaitMs })` instead of boolean `saveState` or `requestSaveWithin`. +- `rivetkit-core` actor state is post-boot delta-only; bootstrap snapshots use `set_state_initial`, and runtime state writes must flow through `request_save` / `save_state(Vec)`. +- `rivetkit-core` save hints use `RequestSaveOpts { immediate, max_wait_ms }`; TypeScript/NAPI callers use `ctx.requestSave({ immediate, maxWaitMs })`. +- Immediate native actor saves should call `ctx.requestSaveAndWait({ immediate: true })`; `serializeForTick("save")` should only run through the `serializeState` callback. +- Hibernatable connection state mutations should flow through core `ConnHandle::set_state` dirty tracking; TS adapters should not keep per-conn `persistChanged` or manual request-save callbacks. +- Hibernatable websocket `gateway_id` and `request_id` are fixed `[u8; 4]` values matching BARE `data[4]`; validate slices with `hibernatable_id_from_slice(...)` and do not use engine 19-byte `Id`. +- RivetKit core state-management API rules are documented in `docs-internal/engine/rivetkit-core-state-management.md`; update that page when changing `request_save`, `save_state`, `persist_state`, or `set_state_initial` semantics. +- `rivetkit-core` `Schedule` starts `dirty_since_push` as true, sets it true on schedule mutations, and skips envoy alarm pushes only after a successful in-process push has made the schedule clean. +- `rivetkit-core` stores the last pushed driver alarm at actor KV key `[6]` (`LAST_PUSHED_ALARM_KEY`) and loads it during actor startup to skip identical future alarm pushes across generations. +- User-facing `onDisconnect` work should run inside `ActorContext::with_disconnect_callback(...)` so `pending_disconnect_count` gates sleep until the async callback finishes. +- `rivetkit-core` websocket close callbacks are async `BoxFuture`s; await `WebSocket::close(...)` and `dispatch_close_event(...)`, while send/message callbacks remain sync for now. +- Native `WebSocket.close(...)` returns a Promise after the async core close conversion; TS `VirtualWebSocket` adapters should fire it through `void callNative(...)` to preserve the public sync close shape. +- NAPI websocket async handlers need one `WebSocketCallbackRegion` token per promise-returning handler; a single shared region slot lets concurrent handlers release each other's sleep guard. +- TypeScript actor vars are JS-runtime-only in `registry/native.ts`; do not reintroduce `ActorVars` in `rivetkit-core` or NAPI `ActorContext.vars/setVars`. +- Async Rust code in RivetKit defaults to `tokio::sync::{Mutex,RwLock}`; reserve `parking_lot` for forced-sync contexts and avoid `std::sync` lock poisoning. +- In `rivetkit-core`, forced-sync runtime wiring slots use `parking_lot`; keep `std::sync::Mutex` only at external API construction boundaries that require it and comment the boundary. +- Schedule alarm dedup should skip only identical concrete timestamps; dirty `None` syncs still need to clear/push the driver alarm. +- In `rivetkit-sqlite` tests, SQLite handles shared across `std::thread` workers are forced-sync and should use `parking_lot::Mutex` with a short comment, not `std::sync::Mutex`. +- In `rivetkit-napi`, sync N-API methods, TSF callback slots, and test `MakeWriter` captures are forced-sync contexts; use `parking_lot::Mutex` and keep guards out of awaits. +- `rivetkit-core` HTTP request drain/rearm waits should use `ActorContext::wait_for_http_requests_idle()` or `wait_for_http_requests_drained(...)`, never a sleep-loop around `can_sleep()`. +- `rivetkit-napi` test-only global serialization should use `parking_lot::Mutex` guards instead of `AtomicBool` spin loops. +- Shared counters with awaiters need both sides of the contract: decrement-to-zero wakes the paired `Notify` / `watch` / permit, and waiters arm before the final counter re-check. +- Async `onStateChange` work must be tracked through core `ActorContext` begin/end methods, and sleep/destroy finalization must wait for idle before sending final save events. +- RivetKit core actor-task logs should use stable string variant labels (`command`, `event`, `outcome`) rather than payload debug dumps; `ActorEvent::kind()` is the shared label source. +- `rivetkit-core` runtime logs should carry stable structured fields (`actor_id`, `reason`, `delta_count`, byte counts, timestamps) instead of payload debug dumps or formatted message strings. +- `rivetkit-core` KV debug logs use `operation`, `key_count`, `result_count`, `elapsed_us`, and `outcome` fields so storage latency can be inspected without logging raw key bytes. +- NAPI bridge debug logs should use stable `kind` fields plus compact payload summaries; do not log raw buffers, full request bodies, or whole payload objects. +- Actor inbox producers in `rivetkit-core` use `try_reserve` before constructing/sending messages so full bounded channels return cheap `actor.overloaded` errors and do not orphan lifecycle reply oneshots. +- `ActorTask` uses separate bounded inboxes for lifecycle commands, client dispatch, internal lifecycle events, and accepted actor events so trusted shutdown/control paths do not compete with untrusted client traffic. +- `ActorTask` shutdown finalize is terminal: the live select loop exits to inline `run_shutdown`, and SleepFinalize/Destroying should not keep servicing lifecycle events. +- Engine actor2 sends at most one Stop per actor instance; duplicate shutdown Stops should assert in debug and warn/drop in release rather than reintroducing multi-reply fan-out. +- Native TS callback errors must encode `deconstructError(...)` for unstructured exceptions before crossing NAPI so plain JS `Error`s become safe `internal_error` payloads. +- `rivetkit-core` engine subprocess supervision lives in `src/engine_process.rs`; `registry.rs` should only call `EngineProcessManager` from serve startup/shutdown plumbing. +- Preloaded KV prefix consumers should trust `requested_prefixes`: consume preloaded entries and skip KV only when the prefix is present; absence means preload skipped/truncated and should fall back. +- Preloaded persisted actor startup is tri-state: `NoBundle` falls back to KV, requested-but-absent `[1]` starts from defaults, and present `[1]` decodes the actor snapshot. +- Queue preload needs both signals: use `requested_get_keys` to distinguish an absent `[5,1,1]` metadata key from an unrequested key, and `requested_prefixes` to know `[5,1,2]+*` message entries are complete enough to consume. +- `rivetkit-core` event fanout is now direct `ActorContext::broadcast(...)` logic; do not reintroduce an `EventBroadcaster` subsystem. +- `rivetkit-core` queue storage lives on `ActorContextInner`, with behavior in `actor/queue.rs` `impl ActorContext` blocks; do not reintroduce `Arc` or a public core `Queue` re-export. +- `rivetkit-core` connection storage lives on `ActorContextInner`, with behavior in `actor/connection.rs` `impl ActorContext` blocks; do not reintroduce `Arc` or a public core `ConnectionManager` re-export. +- `rivetkit-core` sleep state lives on `ActorContextInner` as `SleepState`, with behavior in `actor/sleep.rs` `impl ActorContext` blocks; do not reintroduce a `SleepController` wrapper. +- `ActorContext::build(...)` must seed queue, connection, and sleep config storage from its `ActorConfig`; do not initialize owned subsystem config with `ActorConfig::default()`. +- Sleep grace fires the actor abort signal at grace entry, but NAPI keeps callback teardown on a separate runtime token so onSleep and grace dispatch can still run. +- Active TypeScript run-handler sleep gating belongs to the NAPI user-run JoinHandle, not the core ActorTask adapter loop; queue waits stay sleep-compatible via active_queue_wait_count. +- `rivetkit-core` schedule storage lives on `ActorContextInner`, with behavior in `actor/schedule.rs` `impl ActorContext` blocks; do not reintroduce `Arc` or a public core `Schedule` re-export. +- `rivetkit-core` actor state storage lives on `ActorContextInner`, with behavior in `actor/state.rs` `impl ActorContext` blocks; do not reintroduce `Arc` or a public core `ActorState` re-export. +- Public TS actor config exposes `onWake`, not `onBeforeActorStart`; keep `onBeforeActorStart` as an internal driver/NAPI startup hook. +- Native NAPI `onWake` runs after core marks the actor ready and must fire for both fresh starts and wake starts. +- RivetKit protocol crates with BARE `uint` fields should use `vbare_compiler::Config::with_hash_map()` because `serde_bare::Uint` does not implement `Hash`. +- vbare schemas must define structs before unions reference them; legacy TS schemas may need definition-order cleanup when moved into Rust protocol crates. +- `rivetkit-core` actor/inspector BARE protocol paths should encode/decode through generated protocol crates and `vbare::OwnedVersionedData`, not local BARE cursors or writers. +- Actor-connect local DTOs in `registry/mod.rs` should only derive serde traits for JSON/CBOR decode paths; BARE encode/decode belongs to `rivetkit-client-protocol`. +- vbare types introduced in a later protocol version still need identity converters for skipped earlier versions so embedded latest-version serialization works. +- Protocol crate `build.rs` TS codec generation should mirror `engine/packages/runner-protocol/build.rs`: use `@bare-ts/tools`, post-process imports to `@rivetkit/bare-ts`, and write generated codec imports under `rivetkit-typescript/packages/rivetkit/src/common/bare/generated//`. +- Rust client callers should use `Client::new(ClientConfig::new(endpoint).foo(...))`; `Client::from_endpoint(...)` is the endpoint-only convenience path. +- `rivetkit-client` Cargo integration tests live under `rivetkit-rust/packages/client/tests/`; `src/tests/e2e.rs` is not compiled by Cargo. +- Rust client queue sends use `SendOpts` / `SendAndWaitOpts`; `SendAndWaitOpts.timeout` is a `Duration` encoded as milliseconds in `HttpQueueSendRequest.timeout`. +- Cross-version test snapshots under Ralph branch safety should be generated from `git archive ` temp copies, not checkout/worktrees. +- `test-snapshot-gen` scenarios that need namespace-backed actors should create the default namespace explicitly instead of relying on coordinator side effects. +- Rust client raw HTTP uses `handle.fetch(path, Method, HeaderMap, Option)` and routes to the actor gateway `/request` endpoint via `RemoteManager::send_request`. +- Rust client raw WebSocket uses `handle.web_socket(path, Option>) -> RawWebSocket` and routes to `/websocket/{path}` without client-protocol encoding. +- Rust client connection lifecycle tests should keep the mock websocket open and call `conn.disconnect()` explicitly; otherwise the immediate reconnect loop can make `Disconnected` a transient watch value. +- Rust client event subscriptions return `SubscriptionHandle`; `once_event` takes `FnOnce(Event)` and must send an unsubscribe after the first delivery. +- Rust client mock tests should call `ClientConfig::disable_metadata_lookup(true)` unless the test server implements `/metadata`. +- Rust client `gateway_url()` keeps `get()` and `get_or_create()` handles query-backed with `rvt-*` params; only `get_for_id()` builds a direct `/gateway/{actorId}` URL. +- Rust actor-to-actor calls use `Ctx::client()`, which builds and caches `rivetkit-client` from core Envoy client accessors; core should only expose endpoint/token/namespace/pool-name accessors. +- TypeScript native action callbacks must stay per-actor lock-free; use slow+fast same-actor driver actions and assert interleaved events to catch serialized dispatch. +- Runtime-backed `ActorContext`s should be created with internal `ActorContext::build(...)`; keep `new`/`new_with_kv` for explicit test/convenience contexts and do not reintroduce `Default` or `new_runtime`. +- `rivetkit-core` registry actor task handles live in one `actor_instances: SccHashMap`; use `entry_async` for Active/Stopping state transitions. +- Actor-scoped `ActorContext` side tasks should use `WorkRegistry.shutdown_tasks` so sleep/destroy teardown can drain or abort them; explicit `JoinHandle` slots are for cancelable timers or process-scoped tasks. +- `rivetkit-core` registry code lives under `src/registry/`: keep HTTP framework routes in `http.rs`, inspector routes in `inspector.rs`/`inspector_ws.rs`, websocket transport in `websocket.rs`, actor-connect codecs in `actor_connect.rs`, and envoy callback glue in `envoy_callbacks.rs`. +- `rivetkit-core` actor message payloads live in `src/actor/messages.rs`; lifecycle hook plumbing (`Reply`, `ActorEvents`, `ActorStart`) lives in `src/actor/lifecycle_hooks.rs`. +- Removing dead `rivetkit-napi` exports can touch three surfaces: the Rust `#[napi]` export, generated `index.js`/`index.d.ts`, and manual `wrapper.js`/`wrapper.d.ts`. +- `rivetkit-napi` serves through `CoreRegistry` + `NapiActorFactory`; the legacy `BridgeCallbacks` JSON-envelope envoy path and `JsEnvoyHandle` export are deleted and should stay deleted. +- NAPI `ActorContext.sql()` should return `JsNativeDatabase` directly; do not reintroduce the deleted standalone `SqliteDb` wrapper/export. +- Workflow-engine `flush(...)` must chunk KV writes to actor KV limits (128 entries / 976 KiB payload) and leave dirty markers set until all driver writes/deletions succeed. +- `@rivetkit/traces` chunk writes must stay below the 128 KiB actor KV value limit; the default max chunk is 96 KiB unless multipart storage replaces the single-value format. +- `@rivetkit/traces` write queues should recover each `writeChain` rejection and expose `getLastWriteError()` so one KV failure does not poison later writes. +- Runner-config metadata refresh must purge `namespace.runner_config.get` when it writes `envoyProtocolVersion`; otherwise v2 dispatch can sit behind the 5s runner-config cache TTL. +- Engine integration tests do not start `pegboard_outbound` by default; use `TestOpts::with_pegboard_outbound()` for v2 serverless dispatch coverage. +- Rust client connection maps use `scc::HashMap`; clone event subscription callback `Arc`s out before invoking callbacks or sending subscription messages. +- `ActorMetrics` treats Prometheus as optional runtime diagnostics: construction failures disable actor metrics, while registration collisions warn and leave only the failed collector unregistered. +- Panic audits should separate production code from inline `#[cfg(test)]` modules; the raw required grep intentionally catches test assertions and panic-probe fixtures. +- Inspector auth should flow through core `InspectorAuth`; HTTP and WebSocket bearer parsing should accept case-insensitive `Bearer` with flexible whitespace. +- Inspector HTTP connection payloads should use the documented `{ type, id, details: { type, params, stateEnabled, state, subscriptions, isHibernatable } }` shape. +- Actor-connect hibernatable restore is a websocket reconnect path in `registry/websocket.rs`; actor startup only restores persisted metadata before ready. +- Deleting `@rivetkit/rivetkit-napi` subpaths needs package `exports`, `files`, and `turbo.json` inputs cleaned together; `rivetkit` loads the root NAPI package through the string-joined dynamic import in `registry/native.ts`. + +## 2026-04-22 12:44:38 PDT - US-098 +- Implemented workflow storage flush chunking and dirty-marker retry safety. +- Files changed: `rivetkit-typescript/packages/workflow-engine/CLAUDE.md`, `rivetkit-typescript/packages/workflow-engine/src/storage.ts`, `rivetkit-typescript/packages/workflow-engine/tests/storage.test.ts`, `scripts/ralph/prd.json`, `scripts/ralph/progress.txt`. +- Quality checks: `pnpm test tests/storage.test.ts`;

Do NOT change the TS public actor-authoring API. Do NOT change the wire protocol, KV layout, inspector HTTP API, or engine startup plumbing.\n\n===== SPEED RULES =====\n\n- Green gate per core-side story (US-001..US-004): `cargo build -p rivetkit-core` plus any inline `cargo test -p rivetkit-core` tests added in that story.\n- Green gate per NAPI Rust story (US-005..US-013): `cargo build -p rivetkit-napi` (the adapter crate at `rivetkit-typescript/packages/rivetkit-napi`) plus inline `cargo test` if applicable.\n- Green gate per TS story (US-014..US-016): `pnpm build -F rivetkit` from the TS workspace root, then `pnpm --filter @rivetkit/rivetkit-napi build:force` when the `.node` needs to refresh, then targeted driver tests via `pnpm test` from `rivetkit-typescript/packages/rivetkit`.\n- After NAPI Rust changes, ALWAYS run `pnpm --filter @rivetkit/rivetkit-napi build:force` before any driver test; the normal N-API build skips when a prebuilt `.node` exists.\n- Do NOT run workspace-wide `cargo build` or `cargo test`. Unrelated crates may be red; that's fine.\n- Do NOT write backward-compat shims. This is a hard cutover at the NAPI boundary.\n\n===== DESIGN INVARIANTS =====\n\n- Core owns zero user-level tasks. Adapter owns user tasks via a `JoinSet`.\n- Per-conn event causality is a core guarantee; adapter spawns per event without re-implementing a per-conn queue.\n- `run` handler is NON-FATAL: log Ok/Err, do not cancel actor, do not save state. `ctx.restartRunHandler()` aborts current handle and respawns.\n- `AbortSignal` is synthesized at NAPI on top of a `CancellationToken`. Cancelled ONLY on `Destroy` and adapter end-of-life. NOT cancelled on `Sleep` or `run` exit.\n- Sleep sequence: drain → `onSleep` → drain → inline `onDisconnect` per non-hibernatable → `ctx.disconnect_conns` → (if dirty) `ctx.save_state(deltas)` → reply.\n- Destroy sequence: `abort.cancel()` → `onDestroy` → drain → inline `onDisconnect` per conn → `ctx.disconnect_conns(|_| true)` → (if dirty) `ctx.save_state(deltas)` → reply.\n- `onDisconnect` during shutdown runs inline (NOT via mailbox). `ctx.disconnect_conn(s)` is transport-teardown only and fires no `ConnectionClosed` events.\n- Three-phase connect: `onBeforeConnect` (no conn) → `createConnState` → `onConnect`, all chained inside one `ConnectionOpen` arm.\n- Dirty flag is flipped JS-side by `@rivetkit/on-change` proxy handler; handler calls `ctx.requestSave(false)`. Flags are cleared inside `serializeForTick(reason)` for `save|sleep|destroy` but NOT for `inspector`.\n- `SerializeState` is a single event with a `reason` (Save | Inspector). Sleep/Destroy termination events carry `Reply<()>` only — adapter persists explicitly via `ctx.save_state(deltas)` if anything is dirty.\n- `Action.conn` is `Option` — `None` for alarm-originated actions. User actions must tolerate no-conn dispatch.\n- Per-callback timeouts wrap every TSF with `tokio::time::timeout` using the matching `JsActorConfig.*TimeoutMs` value.\n- Every `Reply` is drop-guarded.

if that passes while the wake-path driver cases still fail, chase the preserved-socket wake stack instead of `registry/native.ts`. +- `NativeActorContext.takePendingHibernationChanges()` is a read-only snapshot of core's pending hibernation removals; the actual consume/restore cycle happens inside `rivetkit-core` `ActorContext::save_state(...)`, so TS can poll it for save gating without clearing the removal set. +- Inspector wire-version negotiation is core-owned now: use `ActorContext.decodeInspectorRequest(...)` / `encodeInspectorResponse(...)` backed by `rivetkit-core`, and do not reintroduce TS-side v1-v4 converter glue. +- Query-backed inspector routes can each hit their own transient `guard/actor_ready_timeout` during startup, so active-workflow inspector tests should poll the exact endpoint they assert on instead of waiting on one route and doing a single fetch against another. +- Before cutting a `workflow-engine` fix for an `actor-workflow` driver failure, rerun the targeted repro plus the full `tests/driver/actor-workflow.test.ts` file; earlier runtime fixes can already have flipped the case green, and guessing at workflow-engine changes is wasted motion. +- Completed `workflow()` runs follow the normal actor `run` contract: after the workflow returns, the actor idles into sleep unless user code explicitly calls `ctx.destroy()`. +- For inspector replay coverage, prove "workflow in flight" with the inspector's overall `workflowState` (`pending`/`running`), not `entryMetadata.status` or `runHandlerActive`; those can lag or disagree across encodings even when replay should still be blocked. +- For active-workflow inspector tests, use a test-controlled deferred block plus an explicit `release()` action instead of step timing; fixed sleeps turn replay/history assertions into flaky bullshit. +- For `actor-inspector` active-workflow regressions, rerun both the full bare `tests/driver/actor-inspector.test.ts` file and the isolated `workflow-history` / `summary` tests; this branch can fail only under full-file load while the single-test rerun comes back green. +- For full bare `actor-inspector` driver runs on this branch, keep a per-test timeout override for the active-workflow `/inspector/workflow-history` and `/inspector/summary` polls; the endpoint polling is correct, but 30s can still be too tight once the run falls back through `guard/actor_ready_timeout` retries. +- Process-global `rivetkit-core` `ActorTask` test hooks (`install_shutdown_cleanup_hook`, lifecycle-event/reply hooks) need actor-id filtering plus a shared async test lock, or parallel `cargo test` runs will happily cross-wire unrelated actors and make you chase ghosts. +- In `rivetkit-core` shutdown-race tests, install `actor::task::install_shutdown_cleanup_hook(...)` to inject assertions immediately after `teardown_sleep_controller()`; trying to catch that window with plain `yield_now()` timing is flaky because the stop reply can complete in the same tick. +- In `rivetkit-core` inspector BARE codecs, schema `uint` fields must serialize through `serde_bare::Uint` and schema `data` fields through `serde_bytes`; raw Rust `u64` / `Vec` serde encoding does not match the generated TypeScript BARE wire format. +- `rivetkit-typescript/packages/rivetkit/tests/driver/shared-harness.ts` mirrors runtime stderr lines containing `[DBG]`; strip temporary debug instrumentation before timing-sensitive driver reruns or hibernation tests or the log spam can fake timeout regressions. +- `POST /inspector/workflow/replay` can legitimately return an empty history snapshot when replaying from the beginning, because the replay endpoint clears persisted workflow history before restarting the workflow. +- During isolated driver reruns, a one-off workflow actor start failure with `no_envoys` can be a runner-registration flake; rerun the exact test once before filing a product bug if the immediate rerun comes back green. +- In `rivetkit-typescript/packages/rivetkit/src/registry/native.ts`, late `registerTask(...)` calls during sleep/finalize teardown can hit `actor task registration is closed` / `not configured`; swallow only that specific bridge error or bare workflow sleep/wake cleanup can crash the runtime and masquerade as `no_envoys`. +- In `rivetkit-typescript/packages/rivetkit/src/registry/native.ts`, keep direct HTTP `/action/*` requests wired to the same `onStateChange` callback path as receive-loop actions; otherwise lifecycle hook behavior diverges between direct fetches and mailbox dispatch. +- In `rivetkit-typescript/packages/rivetkit/src/common/utils.ts::deconstructError`, only pass through canonical structured errors (`instanceof RivetError` or tagged `__type: "RivetError"` with full fields); plain-object lookalikes must still be classified and sanitized. +- Native inspector queue-size reads should come from `ctx.inspectorSnapshot().queueSize` in `rivetkit-core`, not TS-side caches or hardcoded HTTP fallbacks. +- In `rivetkit-core` `ActorTask::run`, bind channel `recv()`s as raw `Option`s and log closure explicitly; `Some(...) = recv()` plus `else => break` swallows which inbox died. +- When `envoy-client` mirrors live actor state into `SharedContext.actors` for sync handle lookups, wrap inserts/removals in `EnvoyContext` helpers so stop-event cleanup updates the async map and the shared mirror in lockstep. +- Once `SleepController::teardown()` starts, `track_shutdown_task(...)` must refuse new work under the same `shutdown_tasks` lock; reopening a fresh `JoinSet` after teardown just leaks late `wait_until(...)` tasks. +- `rivetkit-napi` caches `ActorContextShared` by `actor_id`, so every fresh `run_adapter_loop(...)` must clear per-instance runtime state (`end_reason`, ready/started flags, abort/task hooks) before a wake; otherwise sleep→wake can inherit stale shutdown state and drop post-wake events. +- `rivetkit-napi` `JsActorConfig` is narrower than `rivetkit-core` `FlatActorConfig`; when deleting JS-exposed config fields, keep the Rust conversion explicit and set any wider core-only fields to `None`. +- When native action timeouts originate in Rust (`rivetkit-napi` / `rivetkit-core`), `rivetkit-rust/packages/rivetkit-core/src/registry.rs::inspector_error_status` must map `actor/action_timed_out` to HTTP 408 or clients get the right payload behind the wrong status code. +- On this branch, `vitest -t` can still skip `tests/driver/action-features.test.ts` even with the nested suite path; if that happens, run the full file and grep `/tmp/driver-test-current.log` for the `encoding (bare) > Action Timeouts` pass lines instead of trusting the skipped run. +- Raw `onRequest` HTTP fetches should bypass `maxIncomingMessageSize` / `maxOutgoingMessageSize`; keep those message-size guards on `/action/*` and `/queue/*` HTTP message routes in `rivetkit-typescript/packages/rivetkit/src/registry/native.ts`, not generic `rivetkit-core/src/registry.rs::handle_fetch`. +- Primitive JS<->Rust cancellation bridges in `rivetkit-napi` should pass monotonic token IDs through TSF payloads and poll a shared `scc::HashMap` via a sync N-API function; do not try to smuggle `#[napi]` class instances like `CancellationToken` through callback payload objects. +- `rivetkit-napi` tests that assert on the process-global cancel-token registry should serialize themselves with a test-only guard, or parallel async tests will contaminate the size/cancellation assertions. +- `Queue::wait_for_names(...)` can bridge JS `AbortSignal` through registered native cancel-token IDs, but plain actor queue receives still need the `ActorContext` abort token wired into `Queue::new(...)` so `c.queue.next()` aborts during destroy. +- `SleepController` event-driven drains should wake off `AsyncCounter` zero-transition notifies plus `Notify::notified().enable()` arm-before-check waiters; reintroducing scheduler polling there is just dumb latency. +- Sleep-driven actor shutdown is two-phase now: `SleepGrace` keeps dispatch/save ticks live after an immediate `BeginSleep`, and `SleepFinalize` is the only phase that gates dispatch and sends `FinalizeSleep` teardown work into the adapter. +- For detached `rivetkit-core` lifecycle signals like `ctx.sleep()` / `ctx.destroy()`, rely on the spawned task itself (or an explicit `yield_now()`) for decoupling; adding a fake `sleep(1ms)` only injects jitter. +- For `rivetkit-core` shutdown-side `JoinSet` work, construct the `CountGuard` before `spawn(...)`; teardown can abort before first poll, and a guard created inside the async body will leak the counter. +- Keep `SleepController` region APIs as raw `RegionGuard` counters and put sleep-timer resets, activity notifications, and websocket task metrics in `ActorContext` guard wrappers so RAII migrations do not smuggle side effects into `WorkRegistry`. +- For staged `rivetkit-core` drain migrations, add future-facing counters/guards alongside the legacy `SleepController` fields first, and suppress scaffold-only dead-code locally until the follow-up story wires real call sites. +- Shared Rust async primitives that need to be reused by both `engine/sdks/rust/envoy-client` and `rivetkit-core` should live in `engine/packages/util`; paused-time tests there also need a crate-local `tokio` dev-dependency with `features = ["test-util"]`. +- In `engine/sdks/rust/envoy-client`, sync `EnvoyHandle` accessors for live actor state should read the shared `SharedContext.actors` mirror keyed by actor id/generation; blocking back through the envoy task can panic on current-thread Tokio runtimes. +- Package-local CI guard scripts under non-Rust extensions need to be included in `.github/workflows/rust.yml`'s paths filter or Rust CI will never notice the script changed. +- When filtering a single `rivetkit-typescript/packages/rivetkit/tests/driver/*.test.ts` file with `vitest -t`, include the outer `describeDriverMatrix(...)` suite name before `static registry > encoding (...)` or the whole file gets skipped. +- Driver `vitest -t` filters must also use the exact inner `describe(...)` text from the file, not the progress-template label; examples on this branch include `Action Features`, `Actor onStateChange Tests`, `Actor Database (Raw) Tests`, `Actor Inspector HTTP API`, `Gateway Query URLs`, and `Actor Database PRAGMA Migration Tests`. +- Hot-path shared registries and waiter maps in `rivetkit-napi` / `rivetkit-core` should use `scc::HashMap`, not `Mutex>` or `RwLock>`; the async entry/remove APIs map cleanly onto the bridge and queue call sites. +- In `rivetkit-core`, shutdown-only immediate persistence should chain through `ActorState` and be awaited via `wait_for_pending_state_writes()`; schedule/state helpers must not fire-and-forget extra save tasks during teardown. +- Reply-bearing TSF dispatches in `rivetkit-typescript/packages/rivetkit-napi/src/napi_actor_events.rs` should go through a timed spawn helper, not raw `spawn_reply(...)`, or a hung JS promise can sit in the adapter `JoinSet` until shutdown. +- When porting callback-era Rust actors to typed `rivetkit`, keep runtime-only data that used to live in `ctx.vars()` in an actor-id keyed map initialized from `run(Start)` and removed on exit so helper methods can migrate without signature explosion. +- In `rivetkit-rust/packages/rivetkit/src/context.rs`, hand-write `Clone` for generic typed wrappers like `Ctx` and `ConnCtx`; `#[derive(Clone)]` can accidentally impose `A: Clone` just because the wrapper carries `PhantomData`. +- In `rivetkit-rust/packages/rivetkit/src/event.rs`, keep typed event-wrapper drop-guard tests inline with the module instead of external integration tests when the wrappers or bridge helpers still rely on `pub(crate)` fields like `Reply` slots or `wrap_start::(...)`. +- In `rivetkit-rust/packages/rivetkit`, canned tests that need `wrap_start(...)` or other `pub(crate)` helpers should live under `tests/` and be re-included through a `src/` `#[cfg(test)] #[path = "..."]` shim instead of widening the public API. +- `rivetkit-rust/packages/rivetkit` is not currently listed in the repo-root Rust workspace members, so a literal repo-root `cargo build -p rivetkit` fails before compile; for isolated validation, use a throwaway copied workspace root that adds the crate as a temporary member instead of editing forbidden root manifests. +- When validating `rivetkit` from a throwaway workspace, `librocksdb-sys` can reuse an existing build by pointing `ROCKSDB_LIB_DIR` and `SNAPPY_LIB_DIR` at a repo `target/debug/build/librocksdb-sys-*/out` directory; otherwise the temporary build may die on disk space before it ever reaches your example code. +- When temp-building `rivetkit` against a reused `librocksdb-sys` archive, add `RUSTFLAGS="-C link-arg=-lstdc++"` or the example binary can fail to link with missing C++ stdlib symbols. +- `rivetkit::prelude` is intentionally tiny (`Actor`, `Ctx`, `ConnCtx`, `Event`, `Start`, `Registry`, `anyhow::{Result, anyhow}`); pull richer typed wrappers like `Action`, `Sleep`, or `SerializeState` from top-level `rivetkit::...` exports instead of bloating the prelude again. +- In `rivetkit-rust/packages/rivetkit/src/registry.rs`, keep the typed-to-core bridge in one helper (`build_factory(...)`) and have both `register_with(...)` and tests use it, so `wrap_start::(...)` only has one runtime path to drift. +- In `rivetkit-rust/packages/rivetkit/src/event.rs`, wrappers that hand off replies after moving owned request data should split the `Reply` into a tiny helper wrapper (like `HttpReply`) so deferred responders keep the dropped-reply warning path instead of silently falling through `Reply` drop. +- In `rivetkit-rust/packages/rivetkit`, typed actor-state `StateDelta` builders belong in `src/persist.rs`; `SerializeState`/`Sleep`/`Destroy` wrappers in `src/event.rs` should stay thin and reuse those helpers instead of re-encoding state ad hoc. +- In `rivetkit-rust/packages/rivetkit/src/event.rs`, keep `Action::decode()` errors flat (`anyhow!("...: {error}")`) instead of hiding the serde cause behind `with_context(...)`; callers and tests need the top-level string to preserve messages like `unknown action variant: ...`. +- Typed event wrapper structs in `rivetkit-rust/packages/rivetkit/src/event.rs` should store reply handles as `Option>`; once a wrapper implements `Drop`, later `ok()` / `err()` helpers need `take()` to move the reply out without fighting Rust's move-out-of-Drop rules. +- During staged Rust API rewrites, stale examples can be parked behind `required-features` in `Cargo.toml` so `cargo test` stays green until the dedicated example-migration story lands. +- `rivetkit-rust/packages/rivetkit/src/context.rs` should stay a stateless typed wrapper over `rivetkit-core::ActorContext`: keep actor state in the user receive loop, avoid typed vars/state caches on `Ctx`, and do CBOR encode/decode only at wrapper boundaries like `broadcast` and `ConnCtx`. +- `rivetkit-rust/packages/rivetkit/src/start.rs` should write each `ActorStart.hibernated` state blob back onto the `ConnHandle` before wrapping it as `Hibernated`, so `conn.state()` matches the wake snapshot instead of stale handle state. +- In `rivetkit-rust/packages/rivetkit/src/event.rs`, typed connection-event helpers should reuse `ConnCtx` for CBOR state writes and keep `Reply<()>` handles as `Option` so helper methods can `take()` the reply without breaking the existing drop-warning path. +- Adapter-facing startup helpers should live on `rivetkit-core::ActorContext` and be shared by `ActorTask` plus the NAPI preamble; do not fork alarm-resync or overdue-schedule drain logic into NAPI-only shims. +- On this branch, the native TypeScript actor/connection persistence glue still lives in `rivetkit-typescript/packages/rivetkit/src/registry/native.ts`; story docs that mention split `state-manager.ts` or `connection-manager.ts` files are stale unless those modules get restored first. +- Public TS actor `onWake` currently maps to the adapter's `onBeforeActorStart` callback in `rivetkit-typescript/packages/rivetkit/src/registry/native.ts`; the raw NAPI `onWake` hook is wake-only preamble plumbing. +- Static actor `state` literals in `rivetkit-typescript/packages/rivetkit/src/registry/native.ts` must be `structuredClone(...)`d per actor instance or keyed actors will share mutations. +- Every `NativeConnAdapter` construction path in `rivetkit-typescript/packages/rivetkit/src/registry/native.ts` needs both the `CONN_STATE_MANAGER_SYMBOL` hookup and a `ctx.requestSave(false)` callback, or hibernatable conn mutations/removals stop reaching persistence. +- Durable native actor saves in `rivetkit-typescript/packages/rivetkit/src/registry/native.ts` must use `ctx.saveState(StateDeltaPayload)` and a wired `serializeState` callback; the legacy boolean `ctx.saveState(true)` path only requests a save and returns before the durable commit finishes. +- `rivetkit-napi` Rust-side regressions should be validated with `cargo check -p rivetkit-napi --tests` plus `pnpm --filter @rivetkit/rivetkit-napi build:force`; plain `cargo test -p rivetkit-napi` tries to link a standalone N-API test binary and fails without a live Node N-API runtime. +- `rivetkit-core` receive-loop surface changes need a three-point sweep: `src/actor/callbacks.rs` for the public enum, `src/actor/task.rs` for the runtime emitter, and `tests/modules/task.rs` plus `examples/counter.rs` for direct API coverage. +- `rivetkit-core` receive-loop shutdown persistence is explicit now: `Sleep`/`Destroy` only acknowledge with `Reply<()>`, so adapters/examples/tests must call `ctx.save_state(...)` themselves when they want a final flush, and scheduled actions should arrive as `conn: None` instead of a fake `ConnHandle`. +- `ActorContext::conns()` now returns a guard-backed iterator instead of a `Vec`; use it directly for synchronous scans, but `collect::>()` before any loop body that hits `.await`. +- `ActorContext::disconnect_conns(...)` is best-effort transport teardown: attempt every matching connection, remove the successful disconnects, run connection/sleep bookkeeping, and only then bubble up an aggregated error for any failures. +- Live receive-loop inspector state now comes from `ctx.inspector_attach()` / `ctx.inspector_detach()` + `ctx.subscribe_inspector()`: `ActorTask` debounces `SerializeStateReason::Inspector` via request-save hooks, and websocket handlers should consume the overlay broadcast instead of relying on `InspectorSignal::StateUpdated` for fresh bytes. +- In `rivetkit-typescript/packages/rivetkit-napi/src/napi_actor_events.rs`, inspector `SerializeState` is read-only for the adapter dirty bit; only persisting paths (`Save` or shutdown saves) are allowed to consume and clear pending dirty state. +- NAPI callback payloads build a fresh `ActorContext` wrapper every time, so adapter-owned state like abort tokens, restart hooks, and end reasons must live in shared storage outside `ActorContext::new(...)` or later callbacks lose that state. +- `rivetkit-typescript/packages/rivetkit-napi/src/actor_factory.rs` is now the single receive-loop callback-binding registry: keep TSF slots, payload builders, and `callback_error` / `call_*` bridge helpers there instead of re-creating ad hoc JS conversion code in later adapter stories. +- `rivetkit-typescript/packages/rivetkit-napi/src/napi_actor_events.rs` is the receive-loop execution boundary now; keep `actor_factory.rs` on binding/bridge setup and land event-loop control flow in the dedicated module. +- Receive-loop `SerializeState` handling should stay inline in `napi_actor_events.rs`, reuse `state_deltas_from_payload(...)` from `actor_context.rs`, and only cancel the adapter abort token on `Destroy` or final adapter teardown, not on `Sleep`. +- Adapter-owned long-lived handles like `run` should stay in `napi_actor_events.rs` and be exposed to JS through sync hooks stored on shared `ActorContext` state; use a plain `std::sync::Mutex` for those slots because `restartRunHandler()` is synchronous and must not await or `blocking_lock()` inside Tokio. +- Graceful adapter drains in `napi_actor_events.rs` should use `while let Some(result) = tasks.join_next().await`; `JoinSet::shutdown()` aborts in-flight work and breaks the `Sleep`/`Destroy` ordering guarantees. +- `Sleep` and `Destroy` must set the adapter `end_reason` on both success and error replies; otherwise the outer receive loop keeps consuming queued mailbox events after shutdown has already failed. +- Long-lived NAPI callback bridges that only forward lifecycle signals should `unref()` their `ThreadsafeFunction`, or a waiting Rust task can keep Node alive after user code is done. +- Bare JS-constructed `ActorContext` wrappers are missing the runtime actor inbox wiring; methods like `connectConn()` only work once the context comes from a real runtime-backed actor instance. +- Adapter-only lifecycle timeouts belong on the NAPI boundary: add them to `JsActorConfig` plus `index.d.ts`, but do not thread them into `rivetkit-core::FlatActorConfig` when core does not own that callback. +- Some receive-loop startup helpers in `actor_context.rs` are intentionally adapter-facing shims or no-ops because core already restored alarms/connections before the adapter starts; the adapter's real job is to preserve callback order before it drains the mailbox. +- In `napi_actor_events.rs`, missing action handlers should fail fast before spawning, but once a reply task is spawned its abort branch must send `ActorLifecycle::Stopping` explicitly so the `Reply` drop guard does not paper over shutdown with `dropped_reply`. +- Optional NAPI receive-loop callbacks should keep the TS runtime defaults: missing `onBeforeSubscribe` allows, missing workflow callbacks return `None`, and missing connection lifecycle hooks still accept the connection without inventing conn state. +- `rivetkit-core` private `ActorTask` helpers should be regression-tested in `tests/modules/task.rs` through the existing `#[cfg(test)] #[path = "../../tests/modules/task.rs"]` shim instead of widening visibility or adding test-only public hooks. + diff --git a/scripts/ralph/prd.json b/scripts/ralph/prd.json index 7019b0d02f..a0ed67f4e2 100644 --- a/scripts/ralph/prd.json +++ b/scripts/ralph/prd.json @@ -1,895 +1,6 @@ { - "project": "rivetkit-napi-receive-loop-adapter", - "branchName": "04-19-chore_move_rivetkit_to_task_model", - "description": "Rewrite `rivetkit-typescript/packages/rivetkit-napi/src/actor_factory.rs` to host a Rust-side receive loop that translates `rivetkit-core` `ActorEvent`s into TSF invocations against the existing callback shape used in `feat/sqlite-vfs-v2`.

Adapter owns user tasks via a `JoinSet`.\n- Per-conn event causality is a core guarantee; adapter spawns per event without re-implementing a per-conn queue.\n- `run` handler is NON-FATAL: log Ok/Err, do not cancel actor, do not save state. `ctx.restartRunHandler()` aborts current handle and respawns.\n- `AbortSignal` is synthesized at NAPI on top of a `CancellationToken`. Cancelled ONLY on `Destroy` and adapter end-of-life. NOT cancelled on `Sleep` or `run` exit.\n- Sleep sequence: drain → `onSleep` → drain → inline `onDisconnect` per non-hibernatable → `ctx.disconnect_conns` → (if dirty) `ctx.save_state(deltas)` → reply.\n- Destroy sequence: `abort.cancel()` → `onDestroy` → drain → inline `onDisconnect` per conn → `ctx.disconnect_conns(|_| true)` → (if dirty) `ctx.save_state(deltas)` → reply.\n- `onDisconnect` during shutdown runs inline (NOT via mailbox). `ctx.disconnect_conn(s)` is transport-teardown only and fires no `ConnectionClosed` events.\n- Three-phase connect: `onBeforeConnect` (no conn) → `createConnState` → `onConnect`, all chained inside one `ConnectionOpen` arm.\n- Dirty flag is flipped JS-side by `@rivetkit/on-change` proxy handler; handler calls `ctx.requestSave(false)`. Flags are cleared inside `serializeForTick(reason)` for `save|sleep|destroy` but NOT for `inspector`.\n- `SerializeState` is a single event with a `reason` (Save | Inspector). Sleep/Destroy termination events carry `Reply<()>` only — adapter persists explicitly via `ctx.save_state(deltas)` if anything is dirty.\n- `Action.conn` is `Option` — `None` for alarm-originated actions. User actions must tolerate no-conn dispatch.\n- Per-callback timeouts wrap every TSF with `tokio::time::timeout` using the matching `JsActorConfig.*TimeoutMs` value.\n- Every `Reply` is drop-guarded.

Combining because they are both surgical and share the 'close the door after teardown' theme.\n\n### Issue 1 — envoy-client SharedContext.actors lifecycle (from US-002 audit of 2a95e3057)\n\nUS-002 introduced `SharedContext.actors: Arc>>` as a sync-accessible mirror of `EnvoyContext.actors` so `EnvoyHandle::http_request_counter(...)` can be a synchronous accessor. The mirror is populated in `engine/sdks/rust/envoy-client/src/commands.rs:23-45` via duplicate `or_insert_with(HashMap::new).entry(...)` calls against both `ctx.actors` and `ctx.shared.actors`. Two concrete problems:\n\n1. **No per-actor removal on stop/destroy**. `envoy.rs:335,368` does bulk `shared.actors.lock().clear()` only on full disconnect/shutdown. When a single actor stops or is destroyed, the mirror still holds its entry forever — `http_request_counter` may return a stale counter for a stopped actor via the highest-non-closed-generation fallback.\n2. **Dual-map divergence risk**. No helper wraps the pair. Any future code path that mutates `ctx.actors` without touching `ctx.shared.actors` (or vice versa) silently diverges. This is a CLAUDE.md fail-by-default violation waiting to happen.\n\n### Issue 2 — SleepController post-teardown spawn race (from US-005 audit of 7764a15fd)\n\n`SleepController::teardown()` (sleep.rs:368-379) calls `self.0.work.shutdown_tasks.lock().shutdown().await` to abort outstanding tracked tasks, then replaces the JoinSet with a fresh empty one. The problem: `track_shutdown_task(...)` remains callable after teardown. `finish_shutdown_cleanup` calls `teardown()` but subsequent code in the same function (`wait_for_pending_state_writes`, alarm sync, SQLite cleanup) and any concurrent user callback could still invoke `ctx.wait_until(...)` → `track_shutdown_task`.

Rerunning the full file shows one of two shapes:\n- PASS 21/21 in ~45s when the engine has just been restarted\n- FAIL with `alarms wake actors` hitting 30000ms test timeout; the in-flight `sleepActor.getCounts()` call gets `guard/actor_ready_timeout` for 10s and vitest kills the test\n\nThe adjacent `alarms keep actor awake` is now GREEN after the `dispatch_scheduled_action` wrap-in-`internal_keep_awake` fix that landed last session (rivetkit-rust/packages/rivetkit-core/src/actor/context.rs :1472 area). So the `alarms wake actors` flake is the remaining actor-sleep blocker.\n\nObservation: the test does NOT actually require alarm-driven wake — it just expects `sleepCount === 1` and `startCount === 2` after waiting past the sleep timeout and then calling `getCounts`. The wake happens via the HTTP `getCounts` request, not via the engine alarm. But the scheduled alarm + cancelled engine alarm + persisted scheduled event leaves enough state drift that HTTP-driven wake sometimes stalls for > 10s.\n\nExact symptom from a failing run: after setAlarm at t≈1.977s and sleep timer firing at t≈2.977s, getCounts arrives at t≈3.230s and retries every 10s for 30s with `code=guard/actor_ready_timeout`.

if that passes while the wake-path driver cases still fail, chase the preserved-socket wake stack instead of `registry/native.ts`. -- `NativeActorContext.takePendingHibernationChanges()` is a read-only snapshot of core's pending hibernation removals; the actual consume/restore cycle happens inside `rivetkit-core` `ActorContext::save_state(...)`, so TS can poll it for save gating without clearing the removal set. -- Inspector wire-version negotiation is core-owned now: use `ActorContext.decodeInspectorRequest(...)` / `encodeInspectorResponse(...)` backed by `rivetkit-core`, and do not reintroduce TS-side v1-v4 converter glue. -- Query-backed inspector routes can each hit their own transient `guard/actor_ready_timeout` during startup, so active-workflow inspector tests should poll the exact endpoint they assert on instead of waiting on one route and doing a single fetch against another. -- Before cutting a `workflow-engine` fix for an `actor-workflow` driver failure, rerun the targeted repro plus the full `tests/driver/actor-workflow.test.ts` file; earlier runtime fixes can already have flipped the case green, and guessing at workflow-engine changes is wasted motion. -- Completed `workflow()` runs follow the normal actor `run` contract: after the workflow returns, the actor idles into sleep unless user code explicitly calls `ctx.destroy()`. -- For inspector replay coverage, prove "workflow in flight" with the inspector's overall `workflowState` (`pending`/`running`), not `entryMetadata.status` or `runHandlerActive`; those can lag or disagree across encodings even when replay should still be blocked. -- For active-workflow inspector tests, use a test-controlled deferred block plus an explicit `release()` action instead of step timing; fixed sleeps turn replay/history assertions into flaky bullshit. -- For `actor-inspector` active-workflow regressions, rerun both the full bare `tests/driver/actor-inspector.test.ts` file and the isolated `workflow-history` / `summary` tests; this branch can fail only under full-file load while the single-test rerun comes back green. -- For full bare `actor-inspector` driver runs on this branch, keep a per-test timeout override for the active-workflow `/inspector/workflow-history` and `/inspector/summary` polls; the endpoint polling is correct, but 30s can still be too tight once the run falls back through `guard/actor_ready_timeout` retries. -- Process-global `rivetkit-core` `ActorTask` test hooks (`install_shutdown_cleanup_hook`, lifecycle-event/reply hooks) need actor-id filtering plus a shared async test lock, or parallel `cargo test` runs will happily cross-wire unrelated actors and make you chase ghosts. -- In `rivetkit-core` shutdown-race tests, install `actor::task::install_shutdown_cleanup_hook(...)` to inject assertions immediately after `teardown_sleep_controller()`; trying to catch that window with plain `yield_now()` timing is flaky because the stop reply can complete in the same tick. -- In `rivetkit-core` inspector BARE codecs, schema `uint` fields must serialize through `serde_bare::Uint` and schema `data` fields through `serde_bytes`; raw Rust `u64` / `Vec` serde encoding does not match the generated TypeScript BARE wire format. -- `rivetkit-typescript/packages/rivetkit/tests/driver/shared-harness.ts` mirrors runtime stderr lines containing `[DBG]`; strip temporary debug instrumentation before timing-sensitive driver reruns or hibernation tests or the log spam can fake timeout regressions. -- `POST /inspector/workflow/replay` can legitimately return an empty history snapshot when replaying from the beginning, because the replay endpoint clears persisted workflow history before restarting the workflow. -- During isolated driver reruns, a one-off workflow actor start failure with `no_envoys` can be a runner-registration flake; rerun the exact test once before filing a product bug if the immediate rerun comes back green. -- In `rivetkit-typescript/packages/rivetkit/src/registry/native.ts`, late `registerTask(...)` calls during sleep/finalize teardown can hit `actor task registration is closed` / `not configured`; swallow only that specific bridge error or bare workflow sleep/wake cleanup can crash the runtime and masquerade as `no_envoys`. -- In `rivetkit-typescript/packages/rivetkit/src/registry/native.ts`, keep direct HTTP `/action/*` requests wired to the same `onStateChange` callback path as receive-loop actions; otherwise lifecycle hook behavior diverges between direct fetches and mailbox dispatch. -- In `rivetkit-typescript/packages/rivetkit/src/common/utils.ts::deconstructError`, only pass through canonical structured errors (`instanceof RivetError` or tagged `__type: "RivetError"` with full fields); plain-object lookalikes must still be classified and sanitized. -- Native inspector queue-size reads should come from `ctx.inspectorSnapshot().queueSize` in `rivetkit-core`, not TS-side caches or hardcoded HTTP fallbacks. -- In `rivetkit-core` `ActorTask::run`, bind channel `recv()`s as raw `Option`s and log closure explicitly; `Some(...) = recv()` plus `else => break` swallows which inbox died. -- When `envoy-client` mirrors live actor state into `SharedContext.actors` for sync handle lookups, wrap inserts/removals in `EnvoyContext` helpers so stop-event cleanup updates the async map and the shared mirror in lockstep. -- Once `SleepController::teardown()` starts, `track_shutdown_task(...)` must refuse new work under the same `shutdown_tasks` lock; reopening a fresh `JoinSet` after teardown just leaks late `wait_until(...)` tasks. -- `rivetkit-napi` caches `ActorContextShared` by `actor_id`, so every fresh `run_adapter_loop(...)` must clear per-instance runtime state (`end_reason`, ready/started flags, abort/task hooks) before a wake; otherwise sleep→wake can inherit stale shutdown state and drop post-wake events. -- `rivetkit-napi` `JsActorConfig` is narrower than `rivetkit-core` `FlatActorConfig`; when deleting JS-exposed config fields, keep the Rust conversion explicit and set any wider core-only fields to `None`. -- When native action timeouts originate in Rust (`rivetkit-napi` / `rivetkit-core`), `rivetkit-rust/packages/rivetkit-core/src/registry.rs::inspector_error_status` must map `actor/action_timed_out` to HTTP 408 or clients get the right payload behind the wrong status code. -- On this branch, `vitest -t` can still skip `tests/driver/action-features.test.ts` even with the nested suite path; if that happens, run the full file and grep `/tmp/driver-test-current.log` for the `encoding (bare) > Action Timeouts` pass lines instead of trusting the skipped run. -- Raw `onRequest` HTTP fetches should bypass `maxIncomingMessageSize` / `maxOutgoingMessageSize`; keep those message-size guards on `/action/*` and `/queue/*` HTTP message routes in `rivetkit-typescript/packages/rivetkit/src/registry/native.ts`, not generic `rivetkit-core/src/registry.rs::handle_fetch`. -- Primitive JS<->Rust cancellation bridges in `rivetkit-napi` should pass monotonic token IDs through TSF payloads and poll a shared `scc::HashMap` via a sync N-API function; do not try to smuggle `#[napi]` class instances like `CancellationToken` through callback payload objects. -- `rivetkit-napi` tests that assert on the process-global cancel-token registry should serialize themselves with a test-only guard, or parallel async tests will contaminate the size/cancellation assertions. -- `Queue::wait_for_names(...)` can bridge JS `AbortSignal` through registered native cancel-token IDs, but plain actor queue receives still need the `ActorContext` abort token wired into `Queue::new(...)` so `c.queue.next()` aborts during destroy. -- `SleepController` event-driven drains should wake off `AsyncCounter` zero-transition notifies plus `Notify::notified().enable()` arm-before-check waiters; reintroducing scheduler polling there is just dumb latency. -- Sleep-driven actor shutdown is two-phase now: `SleepGrace` keeps dispatch/save ticks live after an immediate `BeginSleep`, and `SleepFinalize` is the only phase that gates dispatch and sends `FinalizeSleep` teardown work into the adapter. -- For detached `rivetkit-core` lifecycle signals like `ctx.sleep()` / `ctx.destroy()`, rely on the spawned task itself (or an explicit `yield_now()`) for decoupling; adding a fake `sleep(1ms)` only injects jitter. -- For `rivetkit-core` shutdown-side `JoinSet` work, construct the `CountGuard` before `spawn(...)`; teardown can abort before first poll, and a guard created inside the async body will leak the counter. -- Keep `SleepController` region APIs as raw `RegionGuard` counters and put sleep-timer resets, activity notifications, and websocket task metrics in `ActorContext` guard wrappers so RAII migrations do not smuggle side effects into `WorkRegistry`. -- For staged `rivetkit-core` drain migrations, add future-facing counters/guards alongside the legacy `SleepController` fields first, and suppress scaffold-only dead-code locally until the follow-up story wires real call sites. -- Shared Rust async primitives that need to be reused by both `engine/sdks/rust/envoy-client` and `rivetkit-core` should live in `engine/packages/util`; paused-time tests there also need a crate-local `tokio` dev-dependency with `features = ["test-util"]`. -- In `engine/sdks/rust/envoy-client`, sync `EnvoyHandle` accessors for live actor state should read the shared `SharedContext.actors` mirror keyed by actor id/generation; blocking back through the envoy task can panic on current-thread Tokio runtimes. -- Package-local CI guard scripts under non-Rust extensions need to be included in `.github/workflows/rust.yml`'s paths filter or Rust CI will never notice the script changed. -- When filtering a single `rivetkit-typescript/packages/rivetkit/tests/driver/*.test.ts` file with `vitest -t`, include the outer `describeDriverMatrix(...)` suite name before `static registry > encoding (...)` or the whole file gets skipped. -- Driver `vitest -t` filters must also use the exact inner `describe(...)` text from the file, not the progress-template label; examples on this branch include `Action Features`, `Actor onStateChange Tests`, `Actor Database (Raw) Tests`, `Actor Inspector HTTP API`, `Gateway Query URLs`, and `Actor Database PRAGMA Migration Tests`. -- Hot-path shared registries and waiter maps in `rivetkit-napi` / `rivetkit-core` should use `scc::HashMap`, not `Mutex>` or `RwLock>`; the async entry/remove APIs map cleanly onto the bridge and queue call sites. -- In `rivetkit-core`, shutdown-only immediate persistence should chain through `ActorState` and be awaited via `wait_for_pending_state_writes()`; schedule/state helpers must not fire-and-forget extra save tasks during teardown. -- Reply-bearing TSF dispatches in `rivetkit-typescript/packages/rivetkit-napi/src/napi_actor_events.rs` should go through a timed spawn helper, not raw `spawn_reply(...)`, or a hung JS promise can sit in the adapter `JoinSet` until shutdown. -- When porting callback-era Rust actors to typed `rivetkit`, keep runtime-only data that used to live in `ctx.vars()` in an actor-id keyed map initialized from `run(Start)` and removed on exit so helper methods can migrate without signature explosion. -- In `rivetkit-rust/packages/rivetkit/src/context.rs`, hand-write `Clone` for generic typed wrappers like `Ctx` and `ConnCtx`; `#[derive(Clone)]` can accidentally impose `A: Clone` just because the wrapper carries `PhantomData`. -- In `rivetkit-rust/packages/rivetkit/src/event.rs`, keep typed event-wrapper drop-guard tests inline with the module instead of external integration tests when the wrappers or bridge helpers still rely on `pub(crate)` fields like `Reply` slots or `wrap_start::(...)`. -- In `rivetkit-rust/packages/rivetkit`, canned tests that need `wrap_start(...)` or other `pub(crate)` helpers should live under `tests/` and be re-included through a `src/` `#[cfg(test)] #[path = "..."]` shim instead of widening the public API. -- `rivetkit-rust/packages/rivetkit` is not currently listed in the repo-root Rust workspace members, so a literal repo-root `cargo build -p rivetkit` fails before compile; for isolated validation, use a throwaway copied workspace root that adds the crate as a temporary member instead of editing forbidden root manifests. -- When validating `rivetkit` from a throwaway workspace, `librocksdb-sys` can reuse an existing build by pointing `ROCKSDB_LIB_DIR` and `SNAPPY_LIB_DIR` at a repo `target/debug/build/librocksdb-sys-*/out` directory; otherwise the temporary build may die on disk space before it ever reaches your example code. -- When temp-building `rivetkit` against a reused `librocksdb-sys` archive, add `RUSTFLAGS="-C link-arg=-lstdc++"` or the example binary can fail to link with missing C++ stdlib symbols. -- `rivetkit::prelude` is intentionally tiny (`Actor`, `Ctx`, `ConnCtx`, `Event`, `Start`, `Registry`, `anyhow::{Result, anyhow}`); pull richer typed wrappers like `Action`, `Sleep`, or `SerializeState` from top-level `rivetkit::...` exports instead of bloating the prelude again. -- In `rivetkit-rust/packages/rivetkit/src/registry.rs`, keep the typed-to-core bridge in one helper (`build_factory(...)`) and have both `register_with(...)` and tests use it, so `wrap_start::(...)` only has one runtime path to drift. -- In `rivetkit-rust/packages/rivetkit/src/event.rs`, wrappers that hand off replies after moving owned request data should split the `Reply` into a tiny helper wrapper (like `HttpReply`) so deferred responders keep the dropped-reply warning path instead of silently falling through `Reply` drop. -- In `rivetkit-rust/packages/rivetkit`, typed actor-state `StateDelta` builders belong in `src/persist.rs`; `SerializeState`/`Sleep`/`Destroy` wrappers in `src/event.rs` should stay thin and reuse those helpers instead of re-encoding state ad hoc. -- In `rivetkit-rust/packages/rivetkit/src/event.rs`, keep `Action::decode()` errors flat (`anyhow!("...: {error}")`) instead of hiding the serde cause behind `with_context(...)`; callers and tests need the top-level string to preserve messages like `unknown action variant: ...`. -- Typed event wrapper structs in `rivetkit-rust/packages/rivetkit/src/event.rs` should store reply handles as `Option>`; once a wrapper implements `Drop`, later `ok()` / `err()` helpers need `take()` to move the reply out without fighting Rust's move-out-of-Drop rules. -- During staged Rust API rewrites, stale examples can be parked behind `required-features` in `Cargo.toml` so `cargo test` stays green until the dedicated example-migration story lands. -- `rivetkit-rust/packages/rivetkit/src/context.rs` should stay a stateless typed wrapper over `rivetkit-core::ActorContext`: keep actor state in the user receive loop, avoid typed vars/state caches on `Ctx`, and do CBOR encode/decode only at wrapper boundaries like `broadcast` and `ConnCtx`. -- `rivetkit-rust/packages/rivetkit/src/start.rs` should write each `ActorStart.hibernated` state blob back onto the `ConnHandle` before wrapping it as `Hibernated`, so `conn.state()` matches the wake snapshot instead of stale handle state. -- In `rivetkit-rust/packages/rivetkit/src/event.rs`, typed connection-event helpers should reuse `ConnCtx` for CBOR state writes and keep `Reply<()>` handles as `Option` so helper methods can `take()` the reply without breaking the existing drop-warning path. -- Adapter-facing startup helpers should live on `rivetkit-core::ActorContext` and be shared by `ActorTask` plus the NAPI preamble; do not fork alarm-resync or overdue-schedule drain logic into NAPI-only shims. -- On this branch, the native TypeScript actor/connection persistence glue still lives in `rivetkit-typescript/packages/rivetkit/src/registry/native.ts`; story docs that mention split `state-manager.ts` or `connection-manager.ts` files are stale unless those modules get restored first. -- Public TS actor `onWake` currently maps to the adapter's `onBeforeActorStart` callback in `rivetkit-typescript/packages/rivetkit/src/registry/native.ts`; the raw NAPI `onWake` hook is wake-only preamble plumbing. -- Static actor `state` literals in `rivetkit-typescript/packages/rivetkit/src/registry/native.ts` must be `structuredClone(...)`d per actor instance or keyed actors will share mutations. -- Every `NativeConnAdapter` construction path in `rivetkit-typescript/packages/rivetkit/src/registry/native.ts` needs both the `CONN_STATE_MANAGER_SYMBOL` hookup and a `ctx.requestSave(false)` callback, or hibernatable conn mutations/removals stop reaching persistence. -- Durable native actor saves in `rivetkit-typescript/packages/rivetkit/src/registry/native.ts` must use `ctx.saveState(StateDeltaPayload)` and a wired `serializeState` callback; the legacy boolean `ctx.saveState(true)` path only requests a save and returns before the durable commit finishes. -- `rivetkit-napi` Rust-side regressions should be validated with `cargo check -p rivetkit-napi --tests` plus `pnpm --filter @rivetkit/rivetkit-napi build:force`; plain `cargo test -p rivetkit-napi` tries to link a standalone N-API test binary and fails without a live Node N-API runtime. -- `rivetkit-core` receive-loop surface changes need a three-point sweep: `src/actor/callbacks.rs` for the public enum, `src/actor/task.rs` for the runtime emitter, and `tests/modules/task.rs` plus `examples/counter.rs` for direct API coverage. -- `rivetkit-core` receive-loop shutdown persistence is explicit now: `Sleep`/`Destroy` only acknowledge with `Reply<()>`, so adapters/examples/tests must call `ctx.save_state(...)` themselves when they want a final flush, and scheduled actions should arrive as `conn: None` instead of a fake `ConnHandle`. -- `ActorContext::conns()` now returns a guard-backed iterator instead of a `Vec`; use it directly for synchronous scans, but `collect::>()` before any loop body that hits `.await`. -- `ActorContext::disconnect_conns(...)` is best-effort transport teardown: attempt every matching connection, remove the successful disconnects, run connection/sleep bookkeeping, and only then bubble up an aggregated error for any failures. -- Live receive-loop inspector state now comes from `ctx.inspector_attach()` / `ctx.inspector_detach()` + `ctx.subscribe_inspector()`: `ActorTask` debounces `SerializeStateReason::Inspector` via request-save hooks, and websocket handlers should consume the overlay broadcast instead of relying on `InspectorSignal::StateUpdated` for fresh bytes. -- In `rivetkit-typescript/packages/rivetkit-napi/src/napi_actor_events.rs`, inspector `SerializeState` is read-only for the adapter dirty bit; only persisting paths (`Save` or shutdown saves) are allowed to consume and clear pending dirty state. -- NAPI callback payloads build a fresh `ActorContext` wrapper every time, so adapter-owned state like abort tokens, restart hooks, and end reasons must live in shared storage outside `ActorContext::new(...)` or later callbacks lose that state. -- `rivetkit-typescript/packages/rivetkit-napi/src/actor_factory.rs` is now the single receive-loop callback-binding registry: keep TSF slots, payload builders, and `callback_error` / `call_*` bridge helpers there instead of re-creating ad hoc JS conversion code in later adapter stories. -- `rivetkit-typescript/packages/rivetkit-napi/src/napi_actor_events.rs` is the receive-loop execution boundary now; keep `actor_factory.rs` on binding/bridge setup and land event-loop control flow in the dedicated module. -- Receive-loop `SerializeState` handling should stay inline in `napi_actor_events.rs`, reuse `state_deltas_from_payload(...)` from `actor_context.rs`, and only cancel the adapter abort token on `Destroy` or final adapter teardown, not on `Sleep`. -- Adapter-owned long-lived handles like `run` should stay in `napi_actor_events.rs` and be exposed to JS through sync hooks stored on shared `ActorContext` state; use a plain `std::sync::Mutex` for those slots because `restartRunHandler()` is synchronous and must not await or `blocking_lock()` inside Tokio. -- Graceful adapter drains in `napi_actor_events.rs` should use `while let Some(result) = tasks.join_next().await`; `JoinSet::shutdown()` aborts in-flight work and breaks the `Sleep`/`Destroy` ordering guarantees. -- `Sleep` and `Destroy` must set the adapter `end_reason` on both success and error replies; otherwise the outer receive loop keeps consuming queued mailbox events after shutdown has already failed. -- Long-lived NAPI callback bridges that only forward lifecycle signals should `unref()` their `ThreadsafeFunction`, or a waiting Rust task can keep Node alive after user code is done. -- Bare JS-constructed `ActorContext` wrappers are missing the runtime actor inbox wiring; methods like `connectConn()` only work once the context comes from a real runtime-backed actor instance. -- Adapter-only lifecycle timeouts belong on the NAPI boundary: add them to `JsActorConfig` plus `index.d.ts`, but do not thread them into `rivetkit-core::FlatActorConfig` when core does not own that callback. -- Some receive-loop startup helpers in `actor_context.rs` are intentionally adapter-facing shims or no-ops because core already restored alarms/connections before the adapter starts; the adapter's real job is to preserve callback order before it drains the mailbox. -- In `napi_actor_events.rs`, missing action handlers should fail fast before spawning, but once a reply task is spawned its abort branch must send `ActorLifecycle::Stopping` explicitly so the `Reply` drop guard does not paper over shutdown with `dropped_reply`. -- Optional NAPI receive-loop callbacks should keep the TS runtime defaults: missing `onBeforeSubscribe` allows, missing workflow callbacks return `None`, and missing connection lifecycle hooks still accept the connection without inventing conn state. -- `rivetkit-core` private `ActorTask` helpers should be regression-tested in `tests/modules/task.rs` through the existing `#[cfg(test)] #[path = "../../tests/modules/task.rs"]` shim instead of widening visibility or adding test-only public hooks. - -## 2026-04-21 09:47:28 PDT - US-001 -- What was implemented: Added `AsyncCounter` to `rivet-util` with the race-safe zero-notify wait path and exported it from the crate root. -- Files changed: `engine/packages/util/src/async_counter.rs`, `engine/packages/util/src/lib.rs`, `engine/packages/util/Cargo.toml`, `scripts/ralph/prd.json`, `scripts/ralph/progress.txt` -- **Learnings for future iterations:** - - Shared async coordination primitives for `envoy-client` and `rivetkit-core` belong in `engine/packages/util` so later stories do not introduce a garbage new dependency edge. - - `AsyncCounter::wait_zero(...)` should keep the `Notify::notified()` + `enable()` arm-before-check pattern;

every action is activity and can reset the sleep deadline. +- `rivet-data` versioned key wrappers should expose engine `Id` fields as `rivet_util::Id`; convert through generated BARE structs only at serde boundaries to preserve stored bytes. +- Core actor boundary config is `ActorConfigInput`; convert sparse runtime-boundary values with `ActorConfig::from_input(...)`. +- Test-only `rivetkit-core` helpers should use `#[cfg(test)]`; delete genuinely unused internal helpers instead of keeping `#[allow(dead_code)]`. +- `rivetkit-core` actor KV/SQLite subsystems live under `src/actor/`, while root `kv`/`sqlite` module aliases preserve existing `rivetkit_core::kv` and `rivetkit_core::sqlite` callers. +- Preserve structured cross-boundary errors with `RivetError::extract` when forwarding an existing `anyhow::Error`; `anyhow!(error.to_string())` drops group/code/metadata. +- NAPI public validation/state errors should pass through `napi_anyhow_error(...)` with a `RivetError`; the helper's `napi::Error::from_reason(...)` is the intentional structured-prefix bridge. +- `cargo test -p rivetkit-napi --lib` links against Node NAPI symbols and can fail outside Node; use `cargo build -p rivetkit-napi` plus `pnpm --filter @rivetkit/rivetkit-napi build:force` as the native gate. +- NAPI `BridgeCallbacks` response-map entries should be owned by RAII guards so errors, cancellation, and early returns remove pending `response_id` senders. +- Canonical RivetError references in docs use dotted `group.code` form, not slash `group/code` form. +- For Ralph reference-branch audits, use `git show :` and `git grep ` instead of checkout/worktree so the PRD branch never changes. +- Alarm writes made during sleep teardown need an acknowledged envoy-to-actor path; enqueueing on `EnvoyHandle` alone is not enough. +- After native `rivetkit-core` changes, rebuild `@rivetkit/rivetkit-napi` with `pnpm --filter @rivetkit/rivetkit-napi build:force` before trusting TS driver results. +- `rivetkit-core::RegistryDispatcher::handle_fetch` owns framework HTTP routes `/metrics`, `/inspector/*`, `/action/*`, and `/queue/*`; TS NAPI callbacks keep action/queue schema validation and queue `canPublish`. +- HTTP framework routes enforce action timeout and message-size caps in `rivetkit-core/src/registry.rs`; raw user `onRequest` still bypasses those framework guards. +- RivetKit framework HTTP error payloads should omit absent `metadata` for JSON/CBOR responses; explicit `metadata: null` stays distinct from missing metadata. +- Hibernating websocket restored-open messages can arrive before the after-hibernation handler rebinds its receiver; buffer restored `Open` messages on already-open hibernatable requests. +- Hibernatable actor websocket action messages should only be acked after a response/error is produced; dropped sleep-transition actions need to stay unacked so the gateway can replay them after wake. +- SleepGrace dispatch replies must be tracked as shutdown work so sleep finalization does not drop accepted action replies. +- SleepGrace is driven by the main `ActorTask::run` select loop via `SleepGraceState`; do not add a second lifecycle/dispatch select loop for grace-only behavior. +- In-memory KV range deletes should mutate under one write lock with `BTreeMap::retain`; avoid read-collect then write-delete TOCTOU patterns. +- SQLite VFS aux-file create/open paths should mutate `BTreeMap` state under one write lock with `entry(...).or_insert_with(...)`; avoid read-then-write upgrade patterns. +- SQLite VFS test wait counters should pair atomics with `tokio::sync::Notify` and bounded `tokio::time::timeout` waits instead of mutex-backed polling. +- Inspector websocket attach state in `rivetkit-core` is guard-owned; hold `InspectorAttachGuard` for the subscription lifetime instead of manually decrementing counters. +- Actor state persistence should hold `save_guard` only while preparing the snapshot/write batch; use the in-flight write counter + `Notify` when teardown must wait for KV durability. +- Test-only KV hooks should clone the hook out of the stats mutex before invoking it, especially when the hook can block. +- Removing public NAPI methods requires deleting the `#[napi]` Rust export and regenerating `@rivetkit/rivetkit-napi/index.d.ts` with `pnpm --filter @rivetkit/rivetkit-napi build:force`. +- NAPI `ActorContext.saveState` accepts only `StateDeltaPayload`; deferred dirty hints should use `requestSave({ immediate, maxWaitMs })` instead of boolean `saveState` or `requestSaveWithin`. +- `rivetkit-core` actor state is post-boot delta-only; bootstrap snapshots use `set_state_initial`, and runtime state writes must flow through `request_save` / `save_state(Vec)`. +- `rivetkit-core` save hints use `RequestSaveOpts { immediate, max_wait_ms }`; TypeScript/NAPI callers use `ctx.requestSave({ immediate, maxWaitMs })`. +- Immediate native actor saves should call `ctx.requestSaveAndWait({ immediate: true })`; `serializeForTick("save")` should only run through the `serializeState` callback. +- Hibernatable connection state mutations should flow through core `ConnHandle::set_state` dirty tracking; TS adapters should not keep per-conn `persistChanged` or manual request-save callbacks. +- Hibernatable websocket `gateway_id` and `request_id` are fixed `[u8; 4]` values matching BARE `data[4]`; validate slices with `hibernatable_id_from_slice(...)` and do not use engine 19-byte `Id`. +- RivetKit core state-management API rules are documented in `docs-internal/engine/rivetkit-core-state-management.md`; update that page when changing `request_save`, `save_state`, `persist_state`, or `set_state_initial` semantics. +- `rivetkit-core` `Schedule` starts `dirty_since_push` as true, sets it true on schedule mutations, and skips envoy alarm pushes only after a successful in-process push has made the schedule clean. +- `rivetkit-core` stores the last pushed driver alarm at actor KV key `[6]` (`LAST_PUSHED_ALARM_KEY`) and loads it during actor startup to skip identical future alarm pushes across generations. +- User-facing `onDisconnect` work should run inside `ActorContext::with_disconnect_callback(...)` so `pending_disconnect_count` gates sleep until the async callback finishes. +- `rivetkit-core` websocket close callbacks are async `BoxFuture`s; await `WebSocket::close(...)` and `dispatch_close_event(...)`, while send/message callbacks remain sync for now. +- Native `WebSocket.close(...)` returns a Promise after the async core close conversion; TS `VirtualWebSocket` adapters should fire it through `void callNative(...)` to preserve the public sync close shape. +- NAPI websocket async handlers need one `WebSocketCallbackRegion` token per promise-returning handler; a single shared region slot lets concurrent handlers release each other's sleep guard. +- TypeScript actor vars are JS-runtime-only in `registry/native.ts`; do not reintroduce `ActorVars` in `rivetkit-core` or NAPI `ActorContext.vars/setVars`. +- Async Rust code in RivetKit defaults to `tokio::sync::{Mutex,RwLock}`; reserve `parking_lot` for forced-sync contexts and avoid `std::sync` lock poisoning. +- In `rivetkit-core`, forced-sync runtime wiring slots use `parking_lot`; keep `std::sync::Mutex` only at external API construction boundaries that require it and comment the boundary. +- Schedule alarm dedup should skip only identical concrete timestamps; dirty `None` syncs still need to clear/push the driver alarm. +- In `rivetkit-sqlite` tests, SQLite handles shared across `std::thread` workers are forced-sync and should use `parking_lot::Mutex` with a short comment, not `std::sync::Mutex`. +- In `rivetkit-napi`, sync N-API methods, TSF callback slots, and test `MakeWriter` captures are forced-sync contexts; use `parking_lot::Mutex` and keep guards out of awaits. +- `rivetkit-core` HTTP request drain/rearm waits should use `ActorContext::wait_for_http_requests_idle()` or `wait_for_http_requests_drained(...)`, never a sleep-loop around `can_sleep()`. +- `rivetkit-napi` test-only global serialization should use `parking_lot::Mutex` guards instead of `AtomicBool` spin loops. +- Shared counters with awaiters need both sides of the contract: decrement-to-zero wakes the paired `Notify` / `watch` / permit, and waiters arm before the final counter re-check. +- Async `onStateChange` work must be tracked through core `ActorContext` begin/end methods, and sleep/destroy finalization must wait for idle before sending final save events. +- RivetKit core actor-task logs should use stable string variant labels (`command`, `event`, `outcome`) rather than payload debug dumps; `ActorEvent::kind()` is the shared label source. +- `rivetkit-core` runtime logs should carry stable structured fields (`actor_id`, `reason`, `delta_count`, byte counts, timestamps) instead of payload debug dumps or formatted message strings. +- `rivetkit-core` KV debug logs use `operation`, `key_count`, `result_count`, `elapsed_us`, and `outcome` fields so storage latency can be inspected without logging raw key bytes. +- NAPI bridge debug logs should use stable `kind` fields plus compact payload summaries; do not log raw buffers, full request bodies, or whole payload objects. +- Actor inbox producers in `rivetkit-core` use `try_reserve` before constructing/sending messages so full bounded channels return cheap `actor.overloaded` errors and do not orphan lifecycle reply oneshots. +- `ActorTask` uses separate bounded inboxes for lifecycle commands, client dispatch, internal lifecycle events, and accepted actor events so trusted shutdown/control paths do not compete with untrusted client traffic. +- `ActorTask` shutdown finalize is terminal: the live select loop exits to inline `run_shutdown`, and SleepFinalize/Destroying should not keep servicing lifecycle events. +- Engine actor2 sends at most one Stop per actor instance; duplicate shutdown Stops should assert in debug and warn/drop in release rather than reintroducing multi-reply fan-out. +- Native TS callback errors must encode `deconstructError(...)` for unstructured exceptions before crossing NAPI so plain JS `Error`s become safe `internal_error` payloads. +- `rivetkit-core` engine subprocess supervision lives in `src/engine_process.rs`; `registry.rs` should only call `EngineProcessManager` from serve startup/shutdown plumbing. +- Preloaded KV prefix consumers should trust `requested_prefixes`: consume preloaded entries and skip KV only when the prefix is present; absence means preload skipped/truncated and should fall back. +- Preloaded persisted actor startup is tri-state: `NoBundle` falls back to KV, requested-but-absent `[1]` starts from defaults, and present `[1]` decodes the actor snapshot. +- Queue preload needs both signals: use `requested_get_keys` to distinguish an absent `[5,1,1]` metadata key from an unrequested key, and `requested_prefixes` to know `[5,1,2]+*` message entries are complete enough to consume. +- `rivetkit-core` event fanout is now direct `ActorContext::broadcast(...)` logic; do not reintroduce an `EventBroadcaster` subsystem. +- `rivetkit-core` queue storage lives on `ActorContextInner`, with behavior in `actor/queue.rs` `impl ActorContext` blocks; do not reintroduce `Arc` or a public core `Queue` re-export. +- `rivetkit-core` connection storage lives on `ActorContextInner`, with behavior in `actor/connection.rs` `impl ActorContext` blocks; do not reintroduce `Arc` or a public core `ConnectionManager` re-export. +- `rivetkit-core` sleep state lives on `ActorContextInner` as `SleepState`, with behavior in `actor/sleep.rs` `impl ActorContext` blocks; do not reintroduce a `SleepController` wrapper. +- `ActorContext::build(...)` must seed queue, connection, and sleep config storage from its `ActorConfig`; do not initialize owned subsystem config with `ActorConfig::default()`. +- Sleep grace fires the actor abort signal at grace entry, but NAPI keeps callback teardown on a separate runtime token so onSleep and grace dispatch can still run. +- Active TypeScript run-handler sleep gating belongs to the NAPI user-run JoinHandle, not the core ActorTask adapter loop; queue waits stay sleep-compatible via active_queue_wait_count. +- `rivetkit-core` schedule storage lives on `ActorContextInner`, with behavior in `actor/schedule.rs` `impl ActorContext` blocks; do not reintroduce `Arc` or a public core `Schedule` re-export. +- `rivetkit-core` actor state storage lives on `ActorContextInner`, with behavior in `actor/state.rs` `impl ActorContext` blocks; do not reintroduce `Arc` or a public core `ActorState` re-export. +- Public TS actor config exposes `onWake`, not `onBeforeActorStart`; keep `onBeforeActorStart` as an internal driver/NAPI startup hook. +- Native NAPI `onWake` runs after core marks the actor ready and must fire for both fresh starts and wake starts. +- RivetKit protocol crates with BARE `uint` fields should use `vbare_compiler::Config::with_hash_map()` because `serde_bare::Uint` does not implement `Hash`. +- vbare schemas must define structs before unions reference them; legacy TS schemas may need definition-order cleanup when moved into Rust protocol crates. +- `rivetkit-core` actor/inspector BARE protocol paths should encode/decode through generated protocol crates and `vbare::OwnedVersionedData`, not local BARE cursors or writers. +- Actor-connect local DTOs in `registry/mod.rs` should only derive serde traits for JSON/CBOR decode paths; BARE encode/decode belongs to `rivetkit-client-protocol`. +- vbare types introduced in a later protocol version still need identity converters for skipped earlier versions so embedded latest-version serialization works. +- Protocol crate `build.rs` TS codec generation should mirror `engine/packages/runner-protocol/build.rs`: use `@bare-ts/tools`, post-process imports to `@rivetkit/bare-ts`, and write generated codec imports under `rivetkit-typescript/packages/rivetkit/src/common/bare/generated//`. +- Rust client callers should use `Client::new(ClientConfig::new(endpoint).foo(...))`; `Client::from_endpoint(...)` is the endpoint-only convenience path. +- `rivetkit-client` Cargo integration tests live under `rivetkit-rust/packages/client/tests/`; `src/tests/e2e.rs` is not compiled by Cargo. +- Rust client queue sends use `SendOpts` / `SendAndWaitOpts`; `SendAndWaitOpts.timeout` is a `Duration` encoded as milliseconds in `HttpQueueSendRequest.timeout`. +- Cross-version test snapshots under Ralph branch safety should be generated from `git archive ` temp copies, not checkout/worktrees. +- `test-snapshot-gen` scenarios that need namespace-backed actors should create the default namespace explicitly instead of relying on coordinator side effects. +- Rust client raw HTTP uses `handle.fetch(path, Method, HeaderMap, Option)` and routes to the actor gateway `/request` endpoint via `RemoteManager::send_request`. +- Rust client raw WebSocket uses `handle.web_socket(path, Option>) -> RawWebSocket` and routes to `/websocket/{path}` without client-protocol encoding. +- Rust client connection lifecycle tests should keep the mock websocket open and call `conn.disconnect()` explicitly; otherwise the immediate reconnect loop can make `Disconnected` a transient watch value. +- Rust client event subscriptions return `SubscriptionHandle`; `once_event` takes `FnOnce(Event)` and must send an unsubscribe after the first delivery. +- Rust client mock tests should call `ClientConfig::disable_metadata_lookup(true)` unless the test server implements `/metadata`. +- Rust client `gateway_url()` keeps `get()` and `get_or_create()` handles query-backed with `rvt-*` params; only `get_for_id()` builds a direct `/gateway/{actorId}` URL. +- Rust actor-to-actor calls use `Ctx::client()`, which builds and caches `rivetkit-client` from core Envoy client accessors; core should only expose endpoint/token/namespace/pool-name accessors. +- TypeScript native action callbacks must stay per-actor lock-free; use slow+fast same-actor driver actions and assert interleaved events to catch serialized dispatch. +- Runtime-backed `ActorContext`s should be created with internal `ActorContext::build(...)`; keep `new`/`new_with_kv` for explicit test/convenience contexts and do not reintroduce `Default` or `new_runtime`. +- `rivetkit-core` registry actor task handles live in one `actor_instances: SccHashMap`; use `entry_async` for Active/Stopping state transitions. +- Actor-scoped `ActorContext` side tasks should use `WorkRegistry.shutdown_tasks` so sleep/destroy teardown can drain or abort them; explicit `JoinHandle` slots are for cancelable timers or process-scoped tasks. +- `rivetkit-core` registry code lives under `src/registry/`: keep HTTP framework routes in `http.rs`, inspector routes in `inspector.rs`/`inspector_ws.rs`, websocket transport in `websocket.rs`, actor-connect codecs in `actor_connect.rs`, and envoy callback glue in `envoy_callbacks.rs`. +- `rivetkit-core` actor message payloads live in `src/actor/messages.rs`; lifecycle hook plumbing (`Reply`, `ActorEvents`, `ActorStart`) lives in `src/actor/lifecycle_hooks.rs`. +- Removing dead `rivetkit-napi` exports can touch three surfaces: the Rust `#[napi]` export, generated `index.js`/`index.d.ts`, and manual `wrapper.js`/`wrapper.d.ts`. +- `rivetkit-napi` serves through `CoreRegistry` + `NapiActorFactory`; the legacy `BridgeCallbacks` JSON-envelope envoy path and `JsEnvoyHandle` export are deleted and should stay deleted. +- NAPI `ActorContext.sql()` should return `JsNativeDatabase` directly; do not reintroduce the deleted standalone `SqliteDb` wrapper/export. +- Workflow-engine `flush(...)` must chunk KV writes to actor KV limits (128 entries / 976 KiB payload) and leave dirty markers set until all driver writes/deletions succeed. +- `@rivetkit/traces` chunk writes must stay below the 128 KiB actor KV value limit; the default max chunk is 96 KiB unless multipart storage replaces the single-value format. +- `@rivetkit/traces` write queues should recover each `writeChain` rejection and expose `getLastWriteError()` so one KV failure does not poison later writes. +- Runner-config metadata refresh must purge `namespace.runner_config.get` when it writes `envoyProtocolVersion`; otherwise v2 dispatch can sit behind the 5s runner-config cache TTL. +- Engine integration tests do not start `pegboard_outbound` by default; use `TestOpts::with_pegboard_outbound()` for v2 serverless dispatch coverage. +- Rust client connection maps use `scc::HashMap`; clone event subscription callback `Arc`s out before invoking callbacks or sending subscription messages. +- `ActorMetrics` treats Prometheus as optional runtime diagnostics: construction failures disable actor metrics, while registration collisions warn and leave only the failed collector unregistered. +- Panic audits should separate production code from inline `#[cfg(test)]` modules; the raw required grep intentionally catches test assertions and panic-probe fixtures. +- Inspector auth should flow through core `InspectorAuth`; HTTP and WebSocket bearer parsing should accept case-insensitive `Bearer` with flexible whitespace. +- Inspector HTTP connection payloads should use the documented `{ type, id, details: { type, params, stateEnabled, state, subscriptions, isHibernatable } }` shape. +- Actor-connect hibernatable restore is a websocket reconnect path in `registry/websocket.rs`; actor startup only restores persisted metadata before ready. +- Deleting `@rivetkit/rivetkit-napi` subpaths needs package `exports`, `files`, and `turbo.json` inputs cleaned together; `rivetkit` loads the root NAPI package through the string-joined dynamic import in `registry/native.ts`. diff --git a/website/src/content/docs/actors/lifecycle.mdx b/website/src/content/docs/actors/lifecycle.mdx index 8e21399286..01cb001a35 100644 --- a/website/src/content/docs/actors/lifecycle.mdx +++ b/website/src/content/docs/actors/lifecycle.mdx @@ -288,7 +288,7 @@ The handler exposes `c.aborted` for loop checks and `c.abortSignal` for cancelin - The actor may go to sleep at any time during the `run` handler.
