A short writeup at `.agent/notes/flake-.md` with evidence - (log excerpts with `file:line` source pointers, repro command, - proposed fix direction). -2. If the investigation reveals a real bug, a PRD story in - `scripts/ralph/prd.json` following the `US-103` template: id - `US-104` onward, priority relative to the urgency of the bug - (see guidance in each step). Use the python script pattern from - previous sessions: - ```python - import json - with open('scripts/ralph/prd.json') as f: prd = json.load(f) - prd['userStories'].insert(, { ... }) - with open('scripts/ralph/prd.json','w') as f: json.dump(prd, f, indent=2) - ``` - ---- - -### Step 1. Reconfirm state after US-102 + US-103 - -**Why first:** two tests were previously red; both may now be green after -those stories landed. Confirming first may shrink the investigation set. - -**Targets:** -- `actor-error-handling::should convert internal errors to safe format` - (was failing pre-US-102; US-102 should have fixed). -- `actor-workflow::starts child workflows created inside workflow steps` - (was failing pre-US-103 with a double-spawn; may or may not be a side - effect of the sleep-grace fix). - -**Commands:** -```bash -pnpm test tests/driver/actor-error-handling.test.ts \ - -t "static registry.*encoding \(bare\).*Actor Error Handling Tests" \ - > /tmp/driver-logs/error-handling-recheck.log 2>&1 - -pnpm test tests/driver/actor-workflow.test.ts \ - -t "static registry.*encoding \(bare\).*starts child workflows" \ - > /tmp/driver-logs/workflow-child-recheck.log 2>&1 -``` - -**Outcomes:** -- Green → drop from list. -- Red → add to Step 5 (child workflow) or deeper root-cause investigation - for error-handling. Summary: `toRivetError` in `actor/errors.ts` previously - preferred `error.message` over fallback; US-102 moved sanitization to - core's `build_internal`. 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.

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.

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.

Each finding has been challenged by a follow-up verification pass; verdicts annotated inline.

Outside the three layers above; referenced when findings touch SQLite v2 migration or engine-side state. + +User-defined lifecycle hooks (`run`, `onSleep`, `onDestroy`, `onDisconnect`, `onStateChange`, `serializeState`) are **defined in typescript** as user code. They are **dispatched from core** via `ActorEvent` messages (e.g. `ActorEvent::RunGracefulCleanup`) that traverse the napi event channel and trigger the napi adapter to call the typescript callback.

Any "concurrent Stop" or "Stop upgrade" scenario is unreachable by construction. +2. **One actor instance running, cluster-wide.** At any moment, exactly one physical copy of an actor is running across the entire cluster. Failover transitions ownership atomically via engine assignment. Any finding that depends on "two envoys running the same actor concurrently" is infeasible under this invariant. + +These invariants narrow several findings below. --- ## Blockers -### F1. Engine-Destroy doesn't fire `c.aborted` in `onDestroy` +### F3. User's `run` cleanly exits → the one engine Stop no-ops → `onSleep`/`onDestroy` never fire — REAL -**Claim.** When the engine sends `Stop { Destroy }`, `run_shutdown` never calls `ctx.cancel_abort_signal_for_sleep()`. The abort signal only fires for Sleep (because `cancel_abort_signal_for_sleep` runs in `start_sleep_grace`) and for self-initiated destroy via `c.destroy()` (because `mark_destroy_requested` calls it at `context.rs:466`). Engine-initiated Destroy bypasses both paths. +**Layer.** user `run` and `onSleep`/`onDestroy` are **typescript** callbacks; lifecycle-state transitions happen in **core**; dispatch of the callbacks is via **napi** receiving `ActorEvent`s from core. -**Evidence.** `task.rs:1496-1676` (`run_shutdown` body) shows no abort-signal cancel. `task.rs:1497-1519` shows abort-signal cancel is only in `start_sleep_grace`. `context.rs:461-467` shows self-destroy path calls cancel. +**Claim.** If user's typescript `run` handler returns cleanly before the (sole, guaranteed-to-arrive) Stop command arrives, core transitions to `Terminated` in `handle_run_handle_outcome` (`task.rs:1303-1328`), and `begin_stop` on `Terminated` replies `Ok` without emitting grace events (`task.rs:773-776`). The one Stop per generation lands on a dead lifecycle. Hooks never dispatch. -**User-visible impact.** User code in `onDestroy` that checks `c.aborted` sees `false`. Contradicts `lifecycle.mdx:932` which says the abort signal fires before `onDestroy` runs. +**Verdict.** Real. -**Source.** Lifecycle agent (N-11, claimed as new confirmed bug not previously filed). +**User impact.** A typescript actor whose `run` naturally completes (e.g. a task-tree that finishes) never gets its user `onSleep` / `onDestroy` hook invoked, even though the engine does send exactly one Stop. -### F2. 2× `sleepGracePeriod` wall-clock budget +**Desired behavior.** Because exactly one Stop arrives per generation, the correct fix is: clean `run` exit while `Started` must **not** transition to `Terminated`. Instead, stay in a waiting substate (or `Started`) until the Stop arrives. When the Stop arrives, `begin_stop` enters `SleepGrace`/`DestroyGrace` and hooks fire via the normal grace path. `Terminated` should mean "lifecycle fully complete, including hooks." Invariant to enforce: `onSleep` or `onDestroy` fires exactly once per generation, regardless of how `run` returned. -**Claim.** `start_sleep_grace` at `task.rs:1376` computes `deadline = now + sleep_grace_period` for the idle wait. After grace exits, `run_shutdown` at `task.rs:1508-1518` computes a **fresh** `deadline = now + effective_sleep_grace_period()`. Total wall-clock from grace entry to save start can be up to 2× `sleepGracePeriod`. +--- -**User-visible impact.** Users set 15s and actor can take up to 30s to shut down. +## High-priority -**Source.** Lifecycle agent, independently confirmed by me during spec drafting. +### F7. `prepare_v1_migration` resets generation to 1 on every call — REAL (negligible) -### F3. `onSleep` silently doesn't run when `run` already returned +**Layer.** **engine** — `sqlite-storage`. -**Claim.** `request_begin_sleep` at `task.rs:2170-2173` early-returns if `run_handle.is_none()`. So if user's `run` handler exited cleanly before Stop arrived, `ActorEvent::BeginSleep` never enqueues, and the adapter's `onSleep` spawn path at `napi_actor_events.rs:566-575` is never triggered. +**Background for reviewers.** `generation` is sqlite-storage's optimistic concurrency fence for commits. Under the "one actor instance cluster-wide" invariant, there are no concurrent writers, so the fence is protecting against stale retries within a single process, not against two processes. -**Source.** Lifecycle agent. +**Claim.** `engine/packages/sqlite-storage/src/takeover.rs:99` hardcodes `generation: 1` when preparing a v1 migration. -### F4. `run_handle` awaited at end of `run_shutdown`, after hooks +**Verdict.** Real but negligible. Under the one-instance invariant, `prepare_v1_migration` is always the first v2 write for the actor, so `generation: 1` is correct. There's no concurrent writer that could hold a higher generation and get rewound. -**Claim.** Doc contract (`lifecycle.mdx:838-843`): step 2 waits for `run`, step 3 runs `onSleep`. Actual code: `onSleep` spawns from `BeginSleep` at grace entry, and `run_handle.take()` + select-with-sleep happens at `task.rs:1657-1680` (end of `run_shutdown`, after drain/disconnect). +**Desired behavior.** Leave as-is. The "preserve existing generation" hardening is defense-in-depth against a scenario that can't happen under current architectural guarantees. -**User-visible impact.** `onSleep` runs concurrently with user's `run` handler instead of after it. +### F8. Truncate leaks PIDX + DELTA entries above new EOF — REAL -**Source.** Lifecycle agent + spec drafting. +**Layer.** **engine** — shared by `rivetkit-sqlite` (VFS host) and `sqlite-storage` (KV backend). -### F5. Self-initiated `c.destroy()` bypasses grace under the new design +**Claim.** `rivetkit-rust/packages/rivetkit-sqlite/src/vfs.rs:1403-1413` `truncate_main_file` updates `state.db_size_pages` but doesn't delete entries for `pgno > new_size`. `engine/packages/sqlite-storage/src/commit.rs:222` sets the new size; `takeover.rs:258-269` `build_recovery_plan` ignores `pgno`. Compaction (`compaction/shard.rs`) folds stale pages into shards rather than freeing them. -**Claim.** `handle_run_handle_outcome` at `task.rs:1337-1349` sees `destroy_requested` flag when `run` returns, and jumps to `LiveExit::Shutdown` directly. Under the proposed grace-based design, this path skips the grace window entirely, so `onDestroy` never fires for self-initiated destroy. +**Verdict.** Real, unmitigated. -**Source.** Spec correctness agent (B3). +**User impact.** Every `VACUUM`/`DROP TABLE` shrink permanently leaks KV space in the actor's sqlite subspace. Billable against actor storage quota (`sqlite_storage_used` never decrements for the leaked pages). ---- +**Desired behavior.** The commit path should enumerate and delete all `pidx_delta_*` and `pidx_shard_*` entries for `pgno >= new_db_size_pages` whenever `db_size_pages` shrinks. `build_recovery_plan` should also filter orphan entries by `pgno >= head.db_size_pages`. `sqlite_storage_used` must decrement to reflect freed space. Compaction should reclaim (delete) truncated pages, not fold them into shards. -## High-priority +### F9. V1 KV data never cleaned up after successful migration — INTENTIONAL -### F6. SQLite v1→v2 has no cross-process migration fence +**Layer.** **engine** — `pegboard-envoy`. -**Claim.** `SQLITE_MIGRATION_LOCKS` at `engine/packages/pegboard-envoy/src/sqlite_runtime.rs:24` is a `OnceLock>` local to one pegboard-envoy process. Two envoy processes hitting the same actor concurrently (failover, scale-out, split-brain) both pass the origin-None check at `:141-155` and both call `prepare_v1_migration` (`takeover.rs:64`) which wipes chunks/pidx each time. +**Claim.** `engine/packages/pegboard-envoy/src/sqlite_runtime.rs:124-250` (`maybe_migrate_v1_to_v2`) never calls `actor_kv::delete_all`, `delete_range`, or similar on the `0x08` prefix after finalize. `engine/packages/pegboard/src/actor_kv/mod.rs:497` has the `delete_all` helper but it's not wired in. -**Source.** SQLite agent. +**Verdict.** Factually accurate, but the behavior is **intentional**. V1 data is preserved after migration as a safety net in case migration corruption is detected after the fact — operators can fall back to the v1 bytes. A future version may add opt-in cleanup once the v2 path has soaked long enough to trust. -### F7. `prepare_v1_migration` resets generation on every call +**User impact.** Post-migration storage is roughly doubled for the affected actors. Trade-off is deliberate: storage cost vs. corruption-recovery safety net. -**Claim.** `takeover.rs:99` builds `DBHead::new(now_ms)` which hardcodes `generation: 1` (`types.rs:51`). If a stale `MigratingFromV1` exists at generation 5, prepare overwrites to 1. Generation fence in `commit_stage_begin` (`commit.rs:200-206`) cannot distinguish concurrent prepare reset. +**Desired behavior.** No change now. Future work: once v2 has soaked long enough to trust, add an opt-in retention policy (config flag or per-actor age threshold) that triggers `delete_all` on the `0x08` prefix for actors whose v2 meta has been stable for N days / writes. Keep the current behavior as the default until then. -**Source.** SQLite agent. +### F10. 5-minute migration lease blocks crash-recovery restart — REAL (narrow) -### F8. Truncate leaks PIDX + DELTA entries above new EOF +**Layer.** **engine** — `pegboard-envoy`. -**Claim.** `vfs.rs:1403-1413` `truncate_main_file` updates `state.db_size_pages` but does not mark pages `>= new_size` for deletion. `commit.rs:222` sets `head.db_size_pages` but doesn't clear `pidx_delta_key(pgno)` for `pgno > new_db_size_pages`. `build_recovery_plan` (`takeover.rs:222-278`) only filters by `txid > head.head_txid`. +**Background for reviewers.** The migration lease is a wall-clock fence that says "the actor cannot restart a v1→v2 migration for N minutes after the last stage was begun." Under the "one actor instance cluster-wide" invariant, the lease is not protecting against concurrent migrations (impossible by construction); it's a conservative "the prior attempt probably didn't finish cleanly, wait before retrying" timeout after a crash. -**User-visible impact.** Permanent KV-space leak on every shrink. +**Claim.** `engine/packages/pegboard-envoy/src/sqlite_runtime.rs:34` `SQLITE_V1_MIGRATION_LEASE_MS = 5 * 60 * 1000`. If the owning envoy crashes between `commit_stage_begin` and `commit_finalize`, the new owner's restart within 5 min is rejected. -**Source.** SQLite agent. +**Verdict.** Real but narrow. Requires crash during the stage window (typically milliseconds to a few seconds for 128 MiB actors). -### F9. V1 data never cleaned up after successful migration +**User impact.** Affected actors are non-startable for up to 5 min after a rare envoy crash. No data loss — once the lease expires, migration restarts from scratch. -**Claim.** After `commit_finalize` sets origin to `MigratedFromV1` (`sqlite_runtime.rs:234`), the V1 KV entries under `0x08` prefix (`:26`) are left in place. `mod.rs` has `delete_all`, `delete_range` helpers but neither is called from the migration path. +**Desired behavior.** Shorten the lease to reflect real stage-window duration (30-60s), *and* add a production path (not test-only) to invalidate the stale in-progress marker when a new engine `Allocate` assigns the actor. Since only one instance runs cluster-wide, a fresh `Allocate` is authoritative evidence the prior attempt is dead — no need to wait for a wall-clock timeout. -**User-visible impact.** Storage doubles per migrated actor, forever. +### F12. `Registry.handler()` / `Registry.serve()` throw at runtime — REAL -**Source.** SQLite agent. +**Layer.** **typescript** — `@rivetkit/actor` package surface. -### F10. 5-minute migration lease blocks legitimate crash recovery +**Claim.** `rivetkit-typescript/packages/rivetkit/src/registry/index.ts:75-95` throws `removedLegacyRoutingError`. Reference branch (`feat/sqlite-vfs-v2`) returned a real `Response`. -**Claim.** `sqlite_runtime.rs:34, 149-152`. If pegboard-envoy crashes between `commit_stage_begin` and `commit_finalize`, the next start within 5 minutes returns `"sqlite v1 migration for actor ... is already in progress"`. Actor can't start for 5 minutes. +**Verdict.** Real. Intentional per commit `US-035`; error message names replacement (`Registry.startEnvoy()`). -**Source.** SQLite agent. +**User impact.** `export default registry.serve()` / `registry.handler(c.req.raw)` in user typescript code throws on first request. No type-level signal. -### F11. Every actor start probes `sqlite_v1_data_exists` +**Desired behavior.** A custom routing layer is needed to replace the old `handler`/`serve` surface. Until that lands, add `@deprecated` jsdoc annotations pointing at `Registry.startEnvoy()` so users see a compile-time / editor warning before hitting the runtime throw. Document the removal in CHANGELOG.md with a migration example. The custom routing layer is the real long-term fix; the deprecation shim is a stopgap during the gap. -**Claim.** `actor_kv/mod.rs:46-71` issues a range scan with `limit:1` under a fresh transaction even for actors that never had v1 data. Extra UDB RTT on hot actor-start path, forever. +### F13. ~48 typed error classes removed from typescript `./errors` subpath — INTENTIONAL -**Source.** SQLite agent. +**Layer.** **typescript**. -### F12. `Registry.handler()` and `Registry.serve()` throw at runtime +**Claim.** `git show feat/sqlite-vfs-v2:rivetkit-typescript/packages/rivetkit/src/actor/errors.ts` exported 48 classes (`QueueFull`, `ActionTimedOut`, etc.). Current `actor/errors.ts` exports only `RivetError`, `UserError`, alias `ActorError = RivetError`, plus 7 factory helpers. -**Claim.** `rivetkit-typescript/packages/rivetkit/src/registry/index.ts:76, 89-94` throws `"removedLegacyRoutingError"`. Old branch (`feat/sqlite-vfs-v2:rivetkit-typescript/packages/rivetkit/src/registry/index.ts:75-77`) returned a real `Response`. +**Verdict.** Factually accurate, but the behavior is **intentional**. The new design has no concrete error classes; users discriminate via `group`/`code` on `RivetError` using helpers like `isRivetErrorCode(e, "queue", "full")`. The collapse was deliberate. -**User-visible impact.** `export default registry.serve()` breaks instantly. No deprecation notice. +**User impact.** User code doing `catch (e) { if (e instanceof QueueFull) … }` breaks.

Actor-ready / actor-started state lives in napi, not core — REAL -### F15. `ActorError.__type` silently changed +**Layer.** layer violation — **core** vs **napi**. -**Claim.** Reference `actor/errors.ts:17`: `class ActorError extends Error { __type = "ActorError"; … }`. Current `actor/errors.ts:209`: `ActorError = RivetError` whose `__type = "RivetError"`. Tag comparison `err.__type === "ActorError"` stops matching. +**Claim.** Core's `SleepState::ready` and `SleepState::started` AtomicBools (`sleep.rs:39-40`) already feed `can_arm_sleep_timer`. napi *also* has its own `ready`/`started` AtomicBools on `ActorContextShared` (`actor_context.rs:68-69`) with parallel `mark_ready`/`mark_started` logic — including a "cannot start before ready" precondition (`:783-794`). The two are not wired to each other. -**Source.** API parity agent. +**Verdict.** Real. Duplicate state machine. A future V8 runtime would need to reimplement napi's version and separately coordinate with core's. -### F16. Signal-primitive mismatch: `notify_one` vs `notify_waiters` +**Desired behavior.** Deduplicate the state without changing core semantics. Make napi's `ready`/`started` accessors read through to core's existing `SleepState::ready`/`started`. napi's `mark_ready`/`mark_started` become thin forwarders to core's setters. **Do not alter core's current semantics or gating behavior** — this is a pure refactor to remove the parallel copy, not an opportunity to change when/how readiness flips. If the "cannot start before ready" precondition exists in napi for a JS-side ordering reason (TSF callback registration, etc.), keep it on the napi side as a precondition check, still forwarding the state read to core. Net: one source of truth (core), napi is transport; no behavior change. -**Claim.** `AsyncCounter::register_change_notify(&activity_notify)` at `sleep.rs:615` wires counter changes through `notify_waiters()` at `async_counter.rs:79` (no permit storage). The spec wants `notify_one` semantics (stores permit). Mixed shapes cause lost wakes when a counter fires while no waiter is registered (i.e., main loop is inside `.await`). +### F19.

Core's `registry/inspector.rs:385` + `inspector_ws.rs:222, 369` handle the same surface. -**Claim.** `task.rs:1322` writes `self.run_handle = None` but doesn't call `reset_sleep_timer` or notify `activity_notify`. Under the grace-drain predicate `can_finalize_sleep() && run_handle.is_none()`, grace would silently degrade to deadline path whenever `run` exits after the last tracked task. +**Verdict.** Real. Two parallel implementations of inspector state patching, action execution, queue introspection, schema introspection. -**Source.** Spec concurrency agent (§2). +**Desired behavior.** Move **all** inspector logic into core. After the move, there should be **nothing left** for the inspector in the typescript layer — no `ActorInspector` class, no `patchState`/`executeAction`/`getQueueStatus`/`getDatabaseSchema` implementations. Inspector is entirely core-owned. If any TS-specific concerns exist (e.g., user-schema-aware state patching), resolve them by having core call back into TS for the narrow piece that needs user schemas, not by leaving a parallel TS implementation. -### F18. Actor-lifecycle state lives in napi, not core +--- -**Claim.** `rivetkit-typescript/packages/rivetkit-napi/src/actor_context.rs:58-70, 505-522, 770-787` stores `ready: AtomicBool`, `started: AtomicBool` on `ActorContextShared` and exposes `mark_ready`, `mark_started`, `is_ready`, `is_started` through NAPI.

Shutdown-save orchestration duplicated in napi +**Desired behavior.** Delete the `setInterval` poll. Subscribe to napi's `on_cancelled` TSF callback via the NAPI `CancellationToken` class. Dispatch cancellation becomes event-driven: napi invokes the JS callback exactly once when the token is cancelled, typescript awakens, no polling. Tied to F31's consolidation — once the TSF-callback version is canonical, the BigInt registry and its polling consumer both disappear. -**Claim.** `rivetkit-typescript/packages/rivetkit-napi/src/napi_actor_events.rs:624-719` implements `handle_sleep_event`, `handle_destroy_event`, `notify_disconnects_inline`, `maybe_shutdown_save` — sequencing callbacks + conn-disconnect + state-save.

Delete the `Runtime.create` spy. For time-dependent tests, replace `vi.spyOn(Date, "now")` with `vi.useFakeTimers()` + `vi.setSystemTime()` — vitest's built-in deterministic clock. `console.warn` silencing is acceptable as a test-hygiene measure; keep it. + +### F23. `createMockNativeContext` fakes the whole napi surface in typescript tests — REAL + +**Layer.** **typescript** — tests fake the **napi** boundary. + +**Claim.** `rivetkit-typescript/packages/rivetkit/tests/native-save-state.test.ts:14-59` builds full fake `NativeActorContext` via `vi.fn()` for 10+ methods, cast as `unknown as NativeActorContext`.

Parity corrections + +v1 deviated from `feat/sqlite-vfs-v2` in ways that would break the wire protocol or lose behavior. + +### 1.1 Header name is `x-rivet-namespace-name`, not `x-rivet-namespace` + +Source: `feat/sqlite-vfs-v2:rivetkit-typescript/packages/rivetkit/src/serverless/router.ts:33`. + +Fix: in core's `/start` header parser, read `x-rivet-namespace-name`. Grep v1 for `x-rivet-namespace` and rename. + +Success: engine POSTing to `/api/rivet/start` with `x-rivet-namespace-name: ` is accepted. + +### 1.2 `ServerlessStartHeadersSchema` validation rules + +Old schema (`feat/sqlite-vfs-v2:src/runtime-router/router-schema.ts`): + +- `endpoint` — required string, error `"x-rivet-endpoint header is required"`. +- `token` — optional string, error `"x-rivet-token header must be a string"`. +- `poolName` — required string, error `"x-rivet-pool-name header is required"`. +- `namespace` — required string, error `"x-rivet-namespace-name header is required"`. + +Fix: port to Rust as an explicit validation routine. On failure, return HTTP 400 with body `{group: "serverless", code: "invalid_request", message: }`. Preserve message passthrough via the first-failed-field semantics that the old TS `parseResult.error.issues[0]?.message` used. + +### 1.3 `/metadata` is the full `MetadataResponse` + +v1 called this "trivial JSON". It is not. From `feat/sqlite-vfs-v2:src/common/router.ts:114-166`: + +``` +MetadataResponse = { + runtime: "rivetkit", + version: VERSION, // pkg version + envoy: { kind: {serverless:{}} | {normal:{}}, version?: number }, + envoyProtocolVersion: envoyProtocol.VERSION, // @rivetkit/engine-envoy-protocol + actorNames: buildActorNames(config), + clientEndpoint?: string, + clientNamespace?: string, + clientToken?: string, +} +``` + +Fix: implement in core. Since the response depends on TS-only data (pkg VERSION, envoy-protocol VERSION, `buildActorNames` output from Zod-validated user config), pass those into core via the registry NAPI config bag at construction time. Core assembles the response. + +Rationale for not moving `buildActorNames` to Rust: it walks the Zod-typed user `actors` config; Zod validation must stay in TS per CLAUDE.md layer rules. Pre-computing on TS side and handing a `Vec` (or equivalent structured array) to core keeps the boundary clean. + +### 1.4 `publicEndpoint` / `publicNamespace` / `publicToken` resolution chain + +From `feat/sqlite-vfs-v2:src/registry/config/index.ts:238-258`: + +```ts +const publicEndpoint = + parsedPublicEndpoint?.endpoint ?? + (isDevEnv && config.startEngine ? ENGINE_ENDPOINT : undefined); +const publicNamespace = parsedPublicEndpoint?.namespace; +const publicToken = parsedPublicEndpoint?.token ?? config.serverless.publicToken; +``` + +`parsedPublicEndpoint` parses the `https://namespace:token@host` URL auth syntax from `config.serverless.publicEndpoint`. + +Fix: port the resolution to TS (it touches Zod + env-var coalescing + `isDevEnv`, so it stays on the TS side). Pass the three resolved fields into core via the NAPI config bag. Core uses them in `/metadata`. + +### 1.5 `configureServerlessPool` is load-bearing + +From `feat/sqlite-vfs-v2:runtime/index.ts:228`, `startServerless()` calls `configureServerlessPool(config)` when `config.configurePool` is set. That function POSTs to engine `PUT /runner-configs/{poolName}` with: + +``` +serverless: { + url: customConfig.url, + headers: customConfig.headers ?? {}, + request_lifespan: customConfig.requestLifespan ?? 900, // seconds (15 min) + metadata_poll_interval: customConfig.metadataPollInterval ?? 1000, + max_runners: 100_000, + min_runners: 0, + runners_margin: 0, + slots_per_runner: 1, +}, +metadata: customConfig.metadata ?? {}, +drain_on_version_upgrade: customConfig.drainOnVersionUpgrade ?? true, +``` + +Fix: wire into the core-owned `update_runner_config` path (already being moved to core by DT-041). Call from the serverless startup flow when `config.configurePool` is set. Failures log at error level but do NOT throw (matches old behavior — the old `configure.ts` wrapped in try/catch with a "restart this process" log and continued). + +### 1.6 Token dual assignment: keep `runnerConfig.token` and `clientConfig.token` separate + +`feat/sqlite-vfs-v2:src/serverless/router.ts:74-83`: + +```ts +const runnerConfig: RegistryConfig = { ...sharedConfig, token: config.token ?? token }; +const clientConfig: RegistryConfig = { + ...sharedConfig, + // Preserve the configured application token for actor-to-actor calls. + // The start token is only needed for the runner connection and may not + // have gateway permissions. + token: config.token ?? token, +}; +``` + +Both configs get the same `config.token ?? token` fallback but are kept as distinct fields. The comment explicitly says they serve different purposes and may diverge. + +Fix: in core, maintain two distinct resolved tokens (`runner_token`, `client_token`). Do not collapse into one even when their current values are identical. The runner token is used for the `/start` runner handshake; the client token is used for actor-to-actor calls. + +### 1.7 Constants + +Define in core: + +- `ENVOY_SSE_PING_INTERVAL: Duration = Duration::from_millis(1000);` (from `actor-driver.ts:81`) +- `ENVOY_STOP_WAIT_MS: Duration = Duration::from_millis(15_000);` (from `actor-driver.ts:82`) + +Ping loop uses the former. Shutdown coordination uses the latter. + +### 1.8 Abort behavior: stop pinging, do NOT shut down envoy + +v1 spec said abort "shuts down the envoy start path". **Wrong.** Old handler (`actor-driver.ts:795-828`): + +```ts +c.req.raw.signal.addEventListener("abort", () => { + logger().debug("SSE aborted"); +}); +// ... later, inside ping loop: +if (stream.closed || stream.aborted) { /* log + break */ } +``` + +Envoy continues running after the SSE stream aborts. The stream's lifetime decouples from the envoy's. + +Fix: on abort, core terminates ONLY the ping loop. Do NOT call envoy shutdown. Emit one debug log `"SSE aborted"` (match old string for log-grep parity). + +### 1.9 Endpoint + namespace validation are both gated on `config.endpoint` + +`feat/sqlite-vfs-v2:src/serverless/router.ts:56-66`: both `endpointsMatch(endpoint, config.endpoint)` AND `namespace !== config.namespace` checks are inside `if (config.endpoint) { ... }`. If `config.endpoint` is unset, neither validation runs. + +Fix: port as a two-level conditional. **Security note:** §2.5 tightens this — namespace check becomes unconditional when `config.namespace` is set. + +### 1.10 `/` landing text is a literal + +Exact string: `"This is a RivetKit server.\n\nLearn more at https://rivet.dev"`.

Per `CLAUDE.md` "Trust Boundaries" (client↔engine is untrusted) + "Fail-By-Default Runtime", the runner itself must validate.

Default is secure. The flag exists for dev/test loopbacks only and should be documented as such. + +### 2.3 `endpointsMatch` is a misconfig guard, not auth + +Add a code comment on the endpoint-match branch: `// NOTE: endpoint match guards against misconfiguration, not attackers. config.endpoint is typically public. Use x-rivet-token (§2.1) for authentication.` Include the same clarification in the error message returned on mismatch. + +### 2.4 `maxStartPayloadBytes` enforcement + +Add `config.serverless.maxStartPayloadBytes` (default 1 MiB = 1_048_576). Enforce: + +- **TS side**: before calling NAPI, check `request.headers.get("content-length")` (if present) and reject with 413 before buffering. For chunked requests, buffer up to the cap and abort if exceeded. +- **Core side**: defense in depth — after receiving the `Buffer`, verify `len() <= max`, return 413 otherwise. + +### 2.5 Namespace gate unconditional when `config.namespace` is set + +Change from v1.9's conditional (gated on `config.endpoint`) to: if `config.namespace` is set, require `x-rivet-namespace-name` to equal it. Independent of `config.endpoint`. Fail-closed. + +### 2.6 Concurrency cap + +Add `config.serverless.maxConcurrentStarts` (default 10). Core tracks active `/start` SSE streams.

Just a response-splitting prevention guard; relevant if someone later adds an echo or a body-based error surface. + +--- + +## 3. NAPI bridge corrections + +v1 hand-waved streaming mechanics. Concrete fixes: + +### 3.1 Backpressure: `onEvent` returns `Promise` + +Change v1 signature from fire-and-forget callbacks to an awaitable one. Rust `await`s via `ThreadsafeFunction::call_async` (pattern from `rivetkit-napi/src/actor_factory.rs` — grep for `call_async`). TS resolves the Promise from inside the `ReadableStream.pull` handler, gated on `controller.desiredSize > 0`. + +Result: Rust core is paced by the JS consumer. No unbounded TSF queue, no dropped events. + +### 3.2 Single TSF dispatch — collapse `writeChunk` + `endStream` + +Two TSFs break cross-TSF ordering (libuv guarantees per-TSF FIFO, not cross-TSF). Collapse to one tagged-union TSF: + +```rust +#[napi(object)] +pub struct StreamEvent { + pub kind: String, // "chunk" | "end" + pub chunk: Option, + pub error: Option, +} +``` + +TS handler: `(event) => { if (event.kind === "chunk") ... else handleEnd(event.error) }`. Matches the existing `rivetkit-napi/src/websocket.rs:~23` `WebSocketEvent` pattern. + +### 3.3 Abort race: `tokio::select!` on cancel token at every `await` + +Core's `handle_request` body runs inside `tokio::select!` against the cancel token. Every `.await` (including `envoy.started()`, the ping loop's `sleep`, and any TSF `call_async`) is interruptible. + +- Cancel BEFORE Promise resolves: resolve Promise with HTTP 499 Client Closed Request + structured body `{group: "serverless", code: "cancelled"}`. +- Cancel DURING streaming: exit ping loop per §1.8, emit `endStream(None)` with clean termination, do NOT call envoy shutdown. + +### 3.4 Pre-stream vs mid-stream error boundary + +Defer Promise resolve until **all** pre-stream validation succeeds. Specifically, in this order: + +1. Header parse + Zod-equivalent validation (§1.2) — sync; fail → 400. +2. Token auth (§2.1) — sync; fail → 401. +3. Endpoint/namespace match (§1.9, §2.5) — sync; fail → 400 (EndpointMismatch / NamespaceMismatch). +4. Concurrency cap check (§2.6) — sync; fail → 429. +5. Payload size check (§2.4) — sync; fail → 413. +6. `envoy.start_serverless_actor(payload)` payload decode/validation (§2.7) — near-sync; fail → 400. +7. `envoy.started()` await — async but usually instant; fail → 503. +8. All pass → resolve Promise with 200 + `Content-Type: text/event-stream`. Enter ping loop. + +Any post-(8) failure (write fails, envoy stops) terminates via `endStream({group, code, message})`. + +This gives the engine a real HTTP status for every startup failure instead of a truncated stream. + +### 3.5 Post-`endStream` chunks must no-op + +After `endStream` fires (normal end, error, or cancel), subsequent `writeChunk` from core must be dropped silently on the JS side. The TS `ReadableStream` controller is already closed/errored. Core should not call `writeChunk` post-`endStream`, but defend against the race on the JS side too. + +### 3.6 Use `CancellationToken` class, NOT raw `AbortSignal` through NAPI + +Per `docs-internal/engine/napi-bridge.md`: `#[napi(object)]` fields are plain data only; `JsFunction`/TSF inside is forbidden; `AbortSignal` cannot cross `#[napi(object)]`. + +Fix: TS creates `new CancellationToken()` per request, wires `req.signal.addEventListener("abort", () => token.cancel())`, passes `token` as a distinct positional NAPI argument. Core awaits `token.cancelled()` in select arms. + +### 3.7 Flatten callbacks to positional args + +Per `napi-bridge.md` conventions. Final signature: + +``` +handleServerlessRequest( + req: { method, url, headers, body: Buffer }, + onEvent: (event: StreamEvent) => Promise, + cancelToken: CancellationToken, +): Promise<{ status: number, headers: Record }> +``` + +No inline callbacks object. + +### 3.8 Buffer copy: bounded to `/start`, documented + +`handleServerlessRequest` copies the request body once (NAPI Buffer → Rust `Vec`). For `/start`'s ≤1 MiB one-shot payload this is acceptable. Document in core code + the public d.ts: + +> `handleServerlessRequest` is for engine-initiated runner start only. It is NOT a general-purpose HTTP dispatch entrypoint; per-request user data-plane traffic must go through the engine gateway. + +--- + +## 4. Architecture + +### 4.1 `registry.start()` must force `startEngine: true` + +Current `buildServeConfig` at `rivetkit-typescript/packages/rivetkit/src/registry/native.ts:4479` only wires `engineBinaryPath` when `config.startEngine` is truthy. v1's three-line `start()` silently does nothing in the serverful case. + +Fix: `registry.start()` sets `config.startEngine = true` if not already set. Matches old `feat/sqlite-vfs-v2` behavior — `.start()` always assumed a local engine. Fail loudly with a structured `RivetError` if the engine binary cannot be resolved (`@rivetkit/engine-cli`'s `getEnginePath()` throws). + +### 4.2 `printWelcome`: make public on `Runtime` + +v1 called `rt.printWelcome()`. Current `runtime/index.ts:125,128` has `#printWelcome()` private. Fix: rename to public `printWelcome()`. `registry.start()` calls it after `startEnvoy()` resolves. + +### 4.3 `staticDir` serving: documented gap, not wired + +Grep confirmed zero `staticDir` / `static_dir` references in `/home/nathan/r5/rivetkit-rust/`. The engine binary has no static-dir flag to wire to. + +Fix: `registry.start()` ignores `config.staticDir` for now. If `staticDir` is set, emit a one-time warning log: `"staticDir is not yet wired in the native engine runtime; see TODO(issue-TBD)"`. CHANGELOG entry documents the gap as a known regression from `feat/sqlite-vfs-v2`. + +A separate story (NOT this one) adds the engine-side flag. + +### 4.4 Envoy lifecycle: process-global, shared across `/start` requests + +Resolve v1's open question. Decision: **one process-global envoy** owned by the registry runtime, shared across all concurrent `/start` SSE streams. Matches old `this.#envoyStarted.promise` semantics. All `handle_request` invocations ensure it's running via the existing idempotent boot path. + +No per-request envoy. No refcounting. + +### 4.5 Zod / core config boundary: explicit + +- **TS owns**: env-var reading (`RIVET_ENDPOINT`, `RIVET_TOKEN`, etc.), Zod parsing, dev-mode detection (`isDevEnv`), `publicEndpoint` URL auth-syntax parse, defaults. +- **Core owns**: post-parsed primitive values only. Never reads env vars. Never imports Zod. + +The NAPI registry-config bag carries post-parsed fields: `endpoint`, `namespace`, `runner_token`, `client_token`, `serverless.{base_path, max_start_payload_bytes, max_concurrent_starts, unauthenticated, public_endpoint, public_namespace, public_token, configure_pool}`. + +Add this boundary to `rivetkit-typescript/CLAUDE.md` under a new `## Config Boundary` section if not already captured. + +### 4.6 NAPI streaming state is core-owned + +Restate and enforce: core owns event ordering (§3.2 single TSF), backpressure pacing (§3.1 Promise), post-endStream drop defense (§3.5), per-request cancel token (§3.6). NAPI holds only the TSF handle and `CancellationToken` forwarder — zero state machine. + +Update `docs-internal/engine/napi-bridge.md` with the streaming-response pattern if it isn't already documented. + +--- + +## 5. Misc cleanups + +### 5.1 `startServerless` idempotency + +Old `startServerless()` (`feat/sqlite-vfs-v2:runtime/index.ts:217-220`) is idempotent: early-return if already started; assert not serverful. `Registry.handler()` calls this per request. + +Fix: preserve same shape in the new code. `ensureRuntime()` is per-request-idempotent (same as old behavior). Document at the top of `handler()`. + +### 5.2 Story breakdown split + +v1 step 2 bundled router + parser + endpoint-match + SSE pump + tests. Split for parallelism: + +- **2a**: endpoint-match helpers + parity unit tests from §1.11 table. Pure functions.

The values for package version, public client fields, and actor metadata are TS-derived inputs that must be passed into core or handled in TS. +- Parsed config resolves `endpoint`, `namespace`, and `token` from URL auth syntax and env vars. `serverless.publicEndpoint` also supports URL auth syntax and feeds `publicEndpoint`, `publicNamespace`, and `publicToken`. +- `Runtime.startServerless()` calls `configureServerlessPool(config)` when `configurePool` is set. That flow calls `getDatacenters` and `updateRunnerConfig` with the serverless URL, headers, request lifespan default `900`, metadata poll interval default `1000`, `max_runners: 100_000`, `drain_on_version_upgrade: true`, and custom metadata. +- `ENVOY_SSE_PING_INTERVAL` is `1000` ms.

This is the hard part. What is missing is: + +1. A `rivetkit-core` routing layer that turns an HTTP request into a dispatch decision over the 4 routes. +2. A NAPI bridge that carries `Request` in and a streaming SSE `Response` out. +3. TS-side `Registry.handler()` / `.serve()` that wrap the NAPI call. +4. TS-side config plumbing for metadata, public client fields, `configurePool`, and body-size limits. + +## Architecture + +Push the request into Rust. The routing logic, endpoint validation, SSE pump, and envoy coordination all live in `rivetkit-core`. TypeScript is thin glue. + +### Layer split + +- **`rivetkit-core` (Rust)** gains `serverless::handle_request(req: ServerlessRequest) -> ServerlessResponseStream`. Owns URL routing for `/api/rivet/*`, header parsing, endpoint/namespace validation, auth validation, envoy startup, `envoy.start_serverless_actor(payload)`, and the SSE ping loop. Takes config-provided `base_path`, metadata response fields, configured endpoint/namespace/token, and body-size limits. +- **`rivetkit-napi`** exposes one request method with positional arguments: `CoreRegistry.handleServerlessRequest(req, onStreamEvent, cancelToken, serveConfig)`. The stream callback is a single `ThreadsafeFunction` tagged union so chunk and end ordering is FIFO on one TSF. +- **`rivetkit-typescript`** registry `handler(req, opts?)` method. It enforces `maxStartPayloadBytes` before NAPI marshal, wires `Request.signal` to the native `CancellationToken`, feeds a `ReadableStream` from the single stream-event callback, and calls `configureServerlessPool` once when `configurePool` is set. + +### Why not proxy to the engine instead + +The engine is the *caller* of `/start`, not its target. A TS proxy would mean the runner function proxies the engine's call back to the engine, which is a pointless round trip. The runner needs to actually invoke `envoy.start_serverless_actor(payload)` on a local in-process envoy. + +### Why not keep the routing in TS + +- `/` and `/health` are trivial. `/metadata` is not trivial because package version, public client fields, and actor metadata originate in TypeScript. Prefer core-owned routing with those fields passed in `ServeConfig`; keep only the metadata assembly in TS if passing all fields cleanly becomes uglier than the route is worth. +- Endpoint/namespace validation and `endpointsMatch` URL normalization already have incentive to move to core (they inform the envoy boot decision). Putting the thin routing layer in the same place is the natural home. +- A future V8-only runtime binding would have to reimplement the TS-side routing. Keeping it in core means V8 reuses the same logic via different bindings. + +## NAPI bridge design + +### Single entrypoint + +```typescript +// rivetkit-typescript/packages/rivetkit-napi/ (pseudo d.ts) +interface CoreRegistry { + handleServerlessRequest( + req: { + method: string, + url: string, + headers: Record, + body: Buffer, // null/empty Buffer if none + }, + onStreamEvent: (event: + | { kind: "chunk"; chunk: Buffer } + | { kind: "end"; error?: { group: string; code: string; message: string } } + ) => Promise, + cancelToken: CancellationToken, + serveConfig: JsServeConfig, + ): { + status: number, + headers: Record, + }; +} +``` + +The method returns status+headers after core validates the route, start headers, auth token, endpoint/namespace gates, and body size. The response body is delivered asynchronously through `onStreamEvent`. + +### Streaming direction (Rust -> JS) + +`onStreamEvent` is a single `ThreadsafeFunction` exposed to core through an `ActorContext`-style plumbing struct. Core writes SSE chunks (`event: ping\ndata:\n\n`) via `kind: "chunk"` and closes via `kind: "end"`. Use `call_async::>` so TypeScript can apply `ReadableStream` backpressure and so final `end` cannot be dropped behind a full libuv queue. Post-end chunks are ignored in core before they cross NAPI. + +### Body direction (JS -> Rust) + +Request body is a single `Buffer`. `/start` payloads are bounded by `serverless.maxStartPayloadBytes` with a default of `1_048_576` bytes before NAPI marshal. Return `413` on overflow. No per-chunk streaming for inbound bodies in v1. + +### Abort propagation + +TS forwards `req.signal` into a native `CancellationToken`. Core observes the token while waiting for envoy readiness and while running the SSE ping loop. Cancellation ends the response stream for that request; it must not be described as shutting down a shared envoy. If the chosen lifecycle is per-request envoy, request cancellation may drop that request-owned handle after the stream closes. + +### Error handling + +Non-streaming errors (bad headers, auth failure, endpoint mismatch, namespace mismatch, body too large) return `status >= 400` with a structured-error JSON body. Post-header errors from envoy readiness or `start_serverless_actor` route through `kind: "end", error`, because HTTP status is already committed. Both paths use `RivetError::extract`; unstructured errors sanitize through `build_internal`. + +## TypeScript surface + +```typescript +// rivetkit-typescript/packages/rivetkit/src/registry/index.ts + +export type FetchHandler = (req: Request, ...args: unknown[]) => Promise; +export interface ServerlessHandler { fetch: FetchHandler } + +class Registry { + // Receives an engine-POSTed /api/rivet/* request, returns the handler response + // (SSE for /start, JSON/text for others). + async handler(request: Request): Promise { + // Lazily builds native registry/core serverless runtime. + return this.#handleNativeServerlessRequest(request); + } + + // Convenience for `export default registry.serve()` in serverless entrypoints. + serve(): ServerlessHandler { + return { fetch: (req) => this.handler(req) }; + } + + // Starts the native serverful path.

Do not claim the engine subprocess serves static files unless that flag exists and is tested. + +## Out of scope (v1) + +- **CF Workers / V8-only runtimes.** Requires a V8 binding for rivetkit-core that does not exist. +- **Deno / Bun parity testing.** Node is primary; Bun *should* work since it supports NAPI and `fetch`/`Response` are spec-standard. Add Bun to tests as a follow-up if demand. +- **Custom auth hooks between `.handler()` and `/start`.** The built-in `/start` path authenticates `x-rivet-token` against configured `config.token` using constant-time comparison. User middleware is optional extra defense, not the primary auth boundary. +- **Multi-namespace routing.** One `Registry` instance per namespace (same as current `startEnvoy`). +- **Request-body streaming into core.** `/start` payload is bounded and read-once; we do not need chunked inbound bodies. If a future route needs it, add a second `handleServerlessRequest` overload. +- **HTTP trailers, HTTP/2 push.** Not attempted. +- **Non-SSE response streaming.** If a future route returns a non-SSE stream, the same TSF callback approach works; core just writes raw bytes instead of SSE framing. + +## Open questions / out of scope clarifications + +- **`staticDir` support.** There is no Rust engine-process `staticDir` flag today. Preserve static serving in TS or explicitly remove it from `registry.start()`. +- **Endpoint normalization helpers.** The old `normalizeEndpointUrl` + `endpointsMatch` + regional-hostname logic must port to Rust with identical behavior. Write as a pure function in `rivetkit-core` with unit tests mirroring the old TS unit tests. +- **Envoy lifecycle on serverless.** The reference branch constructs a new `EngineActorDriver` for each `/start` request, so different concurrent start headers can coexist. A shared process-global envoy is a behavior change and must either be proven safe or replaced with a per-request/refcounted lifecycle. + +## Implementation story breakdown + +Each item is one Ralph iteration unless noted. + +1. **This spec lands.** +2. `rivetkit-core`: add `serverless` module with `handle_request(...)`, URL router for the 4 paths, start-header parser, auth/endpoint/namespace gates, endpoint-match/normalize helpers ported from TS with unit tests, request body limit handling, metadata response assembly from config-provided fields, and SSE chunker. +3. `rivetkit-napi`: `CoreRegistry.handleServerlessRequest(req, onStreamEvent, cancelToken, serveConfig)` using one stream-event TSF, positional args, `CancellationToken`, and Promise-backed backpressure. +4. `rivetkit-typescript`: `Registry.handler(req)` + `.serve()` implementation. Drop the `removedLegacyRoutingError` throw, enforce `maxStartPayloadBytes`, pass metadata/public fields into `ServeConfig`, wire `configureServerlessPool`, and build the `ReadableStream` around stream events. +5. Driver-test coverage: new `tests/driver/serverless-handler.test.ts` boots a local engine, POSTs a realistic `/start` payload through `registry.handler(req)`, asserts the SSE stream stays open, a `CommandStartActor` reaches the envoy, and aborting the request ends the stream without hanging. Cover `/health`, `/metadata`, `/`, missing headers, bad token, namespace mismatch, and body too large. +6. `registry.start()`: preserve the old HTTP/static behavior or intentionally document the removal. Do not pretend `startEnvoy()` binds user-facing HTTP/static ports. +7. Docs: `website/src/content/docs/actors/serverless.mdx` with Hono/Next.js/etc examples, CHANGELOG, and `.claude/reference/docs-sync.md` note so future changes to the surface get mirrored. +8. (Follow-up) Bun matrix job in CI running the same driver tests against Bun. +9. (Follow-up, out of scope for now) V8 binding for CF Workers. + +Estimated total: 4 meaningful implementation stories (2-5 above), plus docs and the follow-ups.

One Stop command per actor generation. The engine's actor2 workflow sends exactly one `Stop` command per generation — either `Sleep` or `Destroy`, never both, never multiples. Any 'concurrent Stop' or 'Stop upgrade' scenario is unreachable by construction.\n2. One actor instance running, cluster-wide. At any moment, exactly one physical copy of an actor is running across the entire cluster. Failover transitions ownership atomically via engine assignment. Any hazard that depends on 'two envoys running the same actor concurrently' is infeasible under this invariant.\n\n===== LAYER GLOSSARY =====\n\n- core = `rivetkit-rust/packages/rivetkit-core/` — Rust lifecycle/state/dispatch state machine.\n- napi = `rivetkit-typescript/packages/rivetkit-napi/` — Rust NAPI bindings between core and JS.\n- typescript = `rivetkit-typescript/packages/rivetkit/` — TypeScript runtime consumed by user code.\n- engine = `engine/packages/*` — orchestrator (pegboard-envoy, sqlite-storage, actor2). Out of scope except where explicitly cited.\n\nUser-defined hooks (`run`, `onSleep`, `onDestroy`, `onDisconnect`, `onStateChange`, `serializeState`) are defined in typescript but dispatched from core via `ActorEvent` messages.\n\n===== GREEN GATE =====\n\n- Rust stories: `cargo build -p ` plus targeted `cargo test -p `.\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 `.\n- Do NOT run `cargo build --workspace` / `cargo test --workspace`.\n\n===== READ BEFORE STARTING =====\n\n- `.agent/notes/rivetkit-core-review-synthesis.md` is the source of truth for each finding.

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/scripts/ralph/prd.json b/scripts/ralph/prd.json index a0ed67f4e2..abaef3564b 100644 --- a/scripts/ralph/prd.json +++ b/scripts/ralph/prd.json @@ -1,6 +1,806 @@ { - "project": "rivetkit-core-napi-cleanup-and-rust-client-parity", - "branchName": "04-22-chore_fix_remaining_issues_with_rivetkit-core", - "description": "Execute the running complaint log at `.agent/notes/user-complaints.md` and the Rust client parity spec at `.agent/specs/rust-client-parity.md` against `rivetkit-rust/packages/rivetkit-core/`, `rivetkit-rust/packages/rivetkit-sqlite/`, `rivetkit-rust/packages/rivetkit/`, `rivetkit-rust/packages/client/`, and `rivetkit-typescript/packages/rivetkit-napi/`.

After fixing, update `.agent/notes/driver-test-progress.md` to mark the corresponding entry `[x]` and append a PASS log line.\n\n===== FAILING / SKIPPED TESTS =====\n\nFast suite:\n1. actor-conn > Large Payloads > should reject request exceeding maxIncomingMessageSize (timed out 30s)\n2. actor-conn > Large Payloads > should reject response exceeding maxOutgoingMessageSize (timed out 30s)\n3. actor-inspector > POST /inspector/workflow/replay rejects workflows that are currently in flight (timed out 30s)\n4. actor-workflow > workflow steps can destroy the actor (AssertionError: actor still running)\n5. conn-error-serialization > error thrown in createConnState preserves group and code through WebSocket serialization (timed out 30s)\n\nSlow suite:\n6. actor-sleep-db > schedule.after in onSleep persists and fires on wake (AssertionError: expected startCount 2, got 3)\n7. hibernatable-websocket-protocol > SKIP under bare/static — whole suite is gated behind `driverTestConfig.features?.hibernatableWebSocketProtocol`.

JSON only for HTTP inspector endpoints.\n- Errors cross boundaries as universal `RivetError` (group/code/message/metadata).\n\n===== INVARIANTS =====\n\n- Every story must root-cause the failure; no retry-loop flake masking. Tests that time out at 30s almost always indicate a bug in core/napi/typescript that never completes or never surfaces an error, not a 'slow test' that needs a longer timeout.\n- Never use `vi.mock`, `jest.mock`, or module-level mocking; tests run against real infrastructure.\n- Every `vi.waitFor` call must have a one-line comment explaining why polling is necessary.\n- Errors thrown in core/napi/typescript paths must reach the client as structured `RivetError` (group/code/message/metadata) through the relevant transport (WebSocket, HTTP, SSE).\n- If the failure reveals a missing enforcement in core, fix in core (not TS). If it reveals missing translation at the NAPI boundary, fix in NAPI. TS fixes only if the test is itself wrong OR the logic is TS-only (workflow engine, Zod validation).\n\n===== RUN COMMANDS =====\n\nFrom repo root:\n\n- Build TS: `pnpm build -F rivetkit`.\n- Build NAPI (only when Rust under rivetkit-napi or sqlite-native changes): `pnpm --filter @rivetkit/rivetkit-napi build:force`.\n- Targeted driver test (single test): `pnpm -F rivetkit test tests/driver/.test.ts -t \"\"`.\n- Whole driver test file: `pnpm -F rivetkit test tests/driver/.test.ts`.\n- Per `.claude/reference/testing.md`: prefer the single test file via its filename and the `-t` filter while iterating. Verification must run the full file without `-t`.\n\n===== ACCEPTANCE RULE FOR EVERY STORY =====\n\nEvery story MUST include, as acceptance criteria, that the ENTIRE relevant test file (not just the single `-t` filter) passes under the static/http/bare matrix.

Secondary focus: every other published package in `rivetkit-typescript/packages/*/package.json` (not the fixture/example packages and not `rivetkit-napi` native build deps).\n\nGoal: the `dependencies` field of each PUBLISHED package should list ONLY what its runtime source code actually imports under `src/` at runtime. Everything else gets deleted outright, moved to `devDependencies`, or moved to `peerDependencies` (with an explicit reason).\n\nCURRENT DEPENDENCIES of `packages/rivetkit` to audit (direct runtime deps list):\n\n- `@hono/node-server`, `@hono/node-ws`, `@hono/zod-openapi`\n- `@rivet-dev/agent-os-core`\n- `@rivetkit/bare-ts`, `@rivetkit/engine-cli`, `@rivetkit/engine-envoy-protocol`\n- `@rivetkit/rivetkit-napi`, `@rivetkit/traces`, `@rivetkit/virtual-websocket`, `@rivetkit/workflow-engine`\n- `cbor-x`, `get-port`, `hono`, `invariant`, `p-retry`, `pino`, `uuid`, `vbare`, `zod`\n- peerDependencies: `drizzle-kit`, `eventsource`, `ws`\n\nMETHOD (do this for every published package in `rivetkit-typescript/packages/*`):\n\n1. For each declared dependency `X`, run a search for any runtime import — `import ... from \"X\"` or `require(\"X\")` or `import(\"X\")` — across `src/` of that package. Ignore matches in `tests/`, `fixtures/`, `scripts/`, `docs/`, `*.test.ts`, `*.spec.ts`, `vitest.config.*`, `tsup.config.*`, and build config files. Skip type-only imports from `@types/*` — those should be devDependencies.\n2. Categorize each dep into one of:\n - `RUNTIME` — imported by code under `src/` that ships in the built output. Keep in `dependencies`.\n - `DEV-ONLY` — only used by tests, fixtures, build tooling, scripts, or codegen. MOVE to `devDependencies`.\n - `PEER` — consumers are expected to install this themselves (optional adapters like drizzle/eventsource/ws). Keep or promote to `peerDependencies` (mark optional if appropriate).\n - `UNUSED` — no runtime AND no dev-tool caller anywhere in the package. DELETE.\n3. For tree-shakeable optional subpaths (e.g. things gated behind a specific import entrypoint such as `rivetkit/workflow` or `rivetkit/db`), confirm the import graph is tree-shake-clean: importing the main entrypoint must not pull the optional dep. If it does, fix imports before demoting.\n4. Respect `rivetkit-typescript/CLAUDE.md`'s tree-shaking boundaries:\n - `@rivetkit/workflow-engine` must not be imported outside the `rivetkit/workflow` entrypoint.\n - SQLite runtime must stay on `@rivetkit/rivetkit-napi`; do NOT reintroduce WASM SQLite.\n - `rivetkit/db` is the opt-in for SQLite.\n - Core drivers remain SQLite-agnostic.\n5. For each dep you move or delete, write a one-line justification in the story's final progress note in `.agent/notes/dep-audit-rivetkit-typescript.md` (new file). Format: `| package | dep | decision | reason |` table.\n\nCONSTRAINTS:\n\n- Do NOT break any driver tests. Run the static/http/bare fast + slow driver suites end-to-end before marking this story `passes: true`.\n- Do NOT rewrite functionality just to shed a dep. If a dep is load-bearing, leave it alone and note it.\n- Do NOT touch native build-time deps in `packages/rivetkit-napi/package.json` (napi-rs, Cargo deps via `build:force`).\n- Peer-dep changes are user-visible.

READ THAT SPEC FIRST. This story supersedes the deleted `handler-serve-restoration.md` spec; the old TS-reverse-proxy approach was wrong.\n\nCORE INSIGHT: `.handler()` is not a user-traffic gateway. It is the four-route serverless runner endpoint (`GET /`, `GET /health`, `GET /metadata`, `POST /start`) that the engine calls to wake a runner inside a serverless function's request lifespan. The meaningful route is `POST /start`, which accepts a binary envoy-protocol payload, opens an SSE stream back to the engine, calls `envoy.start_serverless_actor(payload)`, and keeps the SSE alive with pings until the envoy stops or the request aborts.\n\nLAYER SPLIT (per spec section 'Architecture'):\n\n1. `rivetkit-core` (Rust) gets a new `serverless` module owning: URL routing for `/api/rivet/*` (configurable base path), `x-rivet-{endpoint,token,pool-name,namespace}` header parsing, endpoint/namespace validation (port `normalizeEndpointUrl` + `endpointsMatch` + regional-hostname logic from `feat/sqlite-vfs-v2:rivetkit-typescript/packages/rivetkit/src/serverless/router.ts` with identical behavior + unit tests), envoy startup reuse, `envoy.start_serverless_actor(payload)` invocation, SSE framing + ping keepalive loop, abort propagation. Single entrypoint: `async fn handle_request(req: ServerlessRequest) -> ServerlessResponseStream`. Rust-only; no NAPI changes yet in this step — core comes first with Rust tests.\n\n2. `rivetkit-napi` exposes exactly one new method: `CoreRegistry.handleServerlessRequest({ method, url, headers, body: Buffer }, { writeChunk, endStream }, abortSignal)`. Returns `Promise<{ status, headers }>`; body chunks flow through `writeChunk` TSF callback; stream terminates via `endStream` (with optional `{ group, code, message }` on error); abort via the passed `AbortSignal` hooked through the existing `cancellation_token.rs` TSF pattern. Thin binding; no logic.\n\n3. `rivetkit-typescript/packages/rivetkit`: `Registry.handler(req)` builds the NAPI payload, creates a `ReadableStream` whose controller is fed by `writeChunk` + closed by `endStream`, returns `new Response(stream, { status, headers })`. `Registry.serve()` returns `{ fetch: (req) => this.handler(req) }`. Drop the `removedLegacyRoutingError` throws from `src/registry/index.ts:75-95`.\n\nSTREAMING SHAPE:\n- Response body streams from Rust to JS via a `ThreadsafeFunction` (`writeChunk`). Core writes pre-framed SSE bytes (e.g. `event: ping\\ndata:\\n\\n`); TS never parses SSE.\n- Request body is a single `Buffer` (CBOR-wrap `{method, url, headers, body}` once on the TS side; pass the Buffer through to Rust without per-chunk inbound streaming — `/start` payloads are bounded and read-once).\n- `req.signal` forwarded as `abortSignal`. `ReadableStream` cancel callback calls a NAPI `cancel()` to stop the Rust SSE loop.\n\nHIGH-LEVEL `registry.start()`:\n- Three-line convenience: `await startEnvoy(); printWelcome();`. The engine subprocess already binds user-facing ports when `startEngine: true`.\n- Static-file serving: check if the engine subprocess already has a `staticDir` flag. If yes, wire `RegistryConfig.staticDir` through to the engine args. If no, document the gap in CHANGELOG and punt to a follow-up story.\n- No new HTTP listeners in rivetkit-typescript.\n\nSCOPE / EXCLUSIONS:\n- Node primary (Bun should also work since it supports NAPI + standard `fetch`/`Response`). Cloudflare Workers / Deno are OUT of scope for v1 (NAPI doesn't load on V8-only runtimes).\n- Inbound request-body streaming is out of scope (bounded `/start` payload only).\n- Response streaming is SSE only in v1 (same framing as old `streamSSE`).

Build host is `rust:1.89.0-bullseye` (Debian 11, OpenSSL 1.1); consumer hosts on Bookworm+/Ubuntu 22.04+/RHEL 9+ have `libssl.so.3`. Every modern Linux consumer is broken.\n\n===== ROOT CAUSE =====\n\nThe `.node` is a pre-compiled blob. The `openssl` dep is not in any npm tree — it was baked in at Rust build time via:\n\n rivetkit-napi → rivetkit-core → rivet-pools → rivet-metrics\n → opentelemetry-otlp → opentelemetry-http\n → reqwest (default features → default-tls → native-tls on Linux → openssl-sys)\n\nEverything else in the workspace already uses rustls (tokio-tungstenite configured with rustls features; `rivetkit-rust/packages/client` explicitly passes rustls). The workspace-level `reqwest` is the leak — it does NOT set `default-features = false`, so every transitive user gets the native-tls default.\n\n===== EXISTING REQWEST USAGES (AUDIT) =====\n\n- `engine/sdks/rust/api-full/Cargo.toml:15`: `reqwest = { version = \"^0.12\", default-features = false, features = [\"json\", \"multipart\"] }` — no TLS features. If the crate makes https calls, add rustls features; if http only, leave as-is. Check with `grep -rn 'https://' engine/sdks/rust/api-full/src/`.\n- `engine/sdks/rust/api-full/rust/Cargo.toml:15`: same as above, duplicate path. Apply same treatment.\n- `rivetkit-rust/packages/client/Cargo.toml:17`: already uses `rustls-tls-native-roots` + `rustls-tls-webpki-roots`. Do NOT touch.\n- Workspace `Cargo.toml`: `[workspace.dependencies.reqwest] version = \"0.12.22\", features = [\"json\"]` — missing `default-features = false` AND missing rustls features. THIS IS THE PRIMARY FIX SITE (grep for `workspace.dependencies.reqwest`, ~line 280ish).\n\n===== VENDORED OPENSSL: BACK IT OUT =====\n\nCommit `f43bc26e8` on this branch added vendored openssl for `aarch64-linux-gnu` as a tactical workaround. That is superseded by this rustls fix. Do NOT revert the commit. Instead, delete the block at the bottom of `rivetkit-typescript/packages/rivetkit-napi/Cargo.toml`:\n\n [target.'cfg(all(target_arch = \"aarch64\", target_env = \"gnu\"))'.dependencies]\n openssl = { version = \"0.10\", features = [\"vendored\"] }\n\nDelete that block AND the preceding comment block. Make the final tree correct; let the reviewer read the diff.\n\n===== WHAT TO DO =====\n\n1. In `/tmp/rivet-publish-fix/Cargo.toml` update the workspace reqwest dep (~line 280ish; grep for `workspace.dependencies.reqwest`):\n```toml\n[workspace.dependencies.reqwest]\nversion = \"0.12.22\"\ndefault-features = false\nfeatures = [\"json\", \"rustls-tls-native-roots\", \"rustls-tls-webpki-roots\"]\n```\nMatch the feature set `tokio-tungstenite` already uses. Don't add `http2` / `charset` unless `cargo tree` shows something needs them.\n\n2. Audit `engine/sdks/rust/api-full` (both Cargo.toml paths). If the crate hits https, add the same rustls features. If http-only (internal service?), leave as-is. Check with `grep -rn 'https://' engine/sdks/rust/api-full/src/`.\n\n3. Remove the vendored-openssl block from `rivetkit-typescript/packages/rivetkit-napi/Cargo.toml` (described above).\n\n4. Update `/tmp/rivet-publish-fix/CLAUDE.md` — add a new short section after `## Async Rust Locks` (~line 161) OR alongside the existing TLS trust roots reference. Style: one-line bullets only (per the `## CLAUDE.md conventions` section):\n```\n## TLS / HTTP clients\n\n- Always use rustls. Never enable `native-tls` / `default-tls` on `reqwest` or anything else on Linux. Consumers (especially `.node` addons published via npm) must have no runtime `libssl.so` dependency.\n- `reqwest` workspace dep must set `default-features = false` and enable `rustls-tls-native-roots` + `rustls-tls-webpki-roots`.

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`. +- ActorTask graceful shutdown hooks are delivered through `ActorEvent::RunGracefulCleanup`; tests that need hook dispatch after a clean run-handle exit can keep `ActorEvents` alive in a detached event-drain task. +- Actor connection actions should validate serialized WebSocket request size before sending so oversized frames reject the pending RPC instead of hanging if an upstream hop drops the frame. +- Actor connection outbound size errors should be returned as structured action error frames; relying only on a WebSocket close can leave the caller's action promise pending. +- Structured WebSocket close reasons in `group.code` format are parsed by `ActorConnRaw` and used to reject both the open promise and pending action promises. +- Driver fixtures that unblock pending workflow steps should latch early releases because inspector tests can observe `pending` before the blocking step installs its deferred. +- Rebuild `@rivetkit/rivetkit-napi` after rivetkit-core changes before rerunning native driver tests, or Vitest can exercise a stale `.node` artifact. +- Sleep DB tests that assert post-sleep effects should avoid exact wake counts unless the fixture pins sleep;

a close frame alone is order-sensitive with hibernatable WebSocket transport. +--- +## 2026-04-22 22:26:51 PDT - DT-003 +- Verified `createConnState` WebSocket failures now reject pending connection actions with the original structured `connection/custom_error` fields. +- Root cause was the connection close path: structured close reasons must reject already-queued action promises, not only the open/connect promise.
