📝 WalkthroughWalkthroughThe API now supports durable, scoped idempotency keys for action invocations. The engine claims invocations before provider dispatch and waits for durable outcomes during replay. The SDK preserves one key across automatic retries. Tests and documentation cover replay, conflicts, handler identity, and single dispatch. ChangesAction invocation idempotency
Estimated code review effort: 4 (Complex) | ~60 minutes Merge Risk: 🔵 Low · up to Retries now replay durable action acknowledgements and suppress duplicate dispatch, but some requests can still receive an initial acknowledgement that disagrees with a later replay, and the published contract may omit key-validation and retry details. These are bounded merge-readiness risks requiring owner follow-up. Sequence Diagram(s)sequenceDiagram

23 to require replayable persistence in runIdempotent after provider dispatch,
so a failed success-record write cannot release the key for a duplicate
actions.invoke execution. Add coverage for one failed record write with exactly
one provider execution, and ensure both decision records describe this behavior.
In `@packages/engine/src/routes/action.ts`:
- Around line 177-212: Replace the runIdempotent flow around
actionEngine.invokeAction with an atomic, durable idempotency claim keyed by
workspace, action, and idempotency key, persisted before provider dispatch so
concurrent requests cannot both invoke the action. Store the invocation result
durably before sending the sendWebhookEvent callback or returning a retryable
response, and ensure retries replay the stored result without creating a second
invocation.

`@packages/engine/src/__tests__/conformance/sdk-contract.test.ts` at line 112.

Fixed CodeRabbit's replay-response finding at exact head The engine now resolves the action before the durable-claim fast replay and passes its Exact-head local verification: focused contract 8/8, engine typecheck/lint, full engine 679/679. The first full run exposed an unrelated fixed-5ms delivery readiness flake (undefined delivery item); its isolated first rerun reproduced, its second rerun passed 53/53, and the subsequent full rerun passed 679/679. @coderabbitai review |

Fixed the remaining CodeRabbit replay-identity finding at exact head The invocation row now snapshots The suggested whole-body equality remains asserted for an unchanged invocation. After an actual handler takeover, whole-body equality would be incorrect: existing engine semantics terminally fail open invocations whose old handler can no longer complete them, so the durable invocation status legitimately advances. The immutable routing identity is preserved while lifecycle state remains current. Exact-head local verification: focused contract and migration suites 12/12; full engine 680/680; full 9-package build; engine lint/typecheck; trajectory JSON parse; @coderabbitai review |

Exact-head disposition and review request for Both exact-head Codex findings are accepted, fixed, answered in words, and resolved. Keyed spawn, release, and node-scoped action replays now wait for a durable dispatch or terminal outcome in both the top-level existing-claim path and branch-local conflict paths. Regressions prove an offline non-queued node action replays 503 rather than failed 201, and a concurrent release replay stays unsettled through the post-send/pre-persistence interval before returning the identical handler node with one frame. Agent-hosted replay deliberately preserves the already-accepted post-send takeover behavior, covered by the existing immutable-handler race regression. Verification: focused node/lifecycle/SDK suites 61/61; full engine 687/687; engine typecheck and lint clean; nine-package build clean; OpenAPI and trajectory parse; diff check clean. @coderabbitai review |

The fix resolves the prior finding.
The new regression covers deletion after the provider frame is sent and before dispatch persistence. The replay returns I found no new issues in the inspected change.

Exact-head disposition and review request for Both newest Codex P2s are accepted, fixed, answered in words, and resolved. Agent-hosted provider dispatch now writes a durable attempt marker at the send boundary. A replay with only a claim waits and returns the terminal 503 if takeover wins before any send; a replay after dispatch started preserves the accepted post-send immutable 201 behavior. Replay classification is centralized from the winning invocation snapshot and is shared by the top-level read plus both node-scoped and agent-hosted insert-conflict branches. Verification: focused node/lifecycle/SDK suites 63/63; pre-send regression ablation fails exactly 201-versus-503 and restored test passes alongside the post-send race; full engine 689/689; engine typecheck and lint clean; nine-package build clean; diff check clean. @coderabbitai review |

1531-1552: 🗄️ Data Integrity & Integration | 🟡 Minor | ⚡ Quick winUse the settled row when the pre-send gate rejects.
The reconciliation at Lines 1535-1540 discards its result.
waitForInvocationReplayOutcomethrows for a terminal failure and for an unresolved claim. It returns normally when the durable row already shows an accepted dispatch or a completed outcome. In that case the code continues to Line 1543 and builds the response from the stale localdispatchedvalue, so it returnsdispatched_node_id: nullandstatus: 'pending'. A later replay of the sameIdempotency-Keyreads the same row throughinvocationAckand returns a populateddispatched_node_id. The original acknowledgement and its replay then disagree.Build the response from the settled row instead.
🛠️ Proposed fix
if (!dispatched.accepted) { // A takeover can invalidate the last-moment adapter gate. Re-read the // durable claim so the original request and its replay agree on the same // pre-send failure instead of returning a pending 201. - await waitForInvocationReplayOutcome( + const settled = await waitForInvocationReplayOutcome( db, workspaceId, invocation, { acceptDispatchStarted: true }, ); + return invocationAck(settled, { actionName }); }🤖 Prompt for AI Agents

The fix addresses the prior finding.
The regression covers the required race. A handler takeover before the socket-owner send returns I found no new issues in the inspected change. I verified the commit by static inspection. I could not run the test suites in this environment. You are interacting with an AI system. |

I found no new issues. The engine now uses the serializable The Node adapter and Cloud NodeDO both verify the durable invocation, handler agent, handler node, and current action handler immediately before accepting the frame. Both implementations record provider acceptance before the dispatch call resolves. Cloud commit I verified the changes by static inspection. I could not run the test suites in this environment.

I found no new issues.
After placement, the handler-node snapshot prevents this cleanup path. After provider dispatch starts, The updated regression verifies that a pre-placement failure deletes the claim and that the same key can create a new invocation after capacity recovery. It also verifies one provider frame. I verified the change by static inspection. I could not run the test suites in this environment.

Closes #354
What changed
Idempotency-Keyon action invocation and replay the durable invocation ackactions.invoke()call and preserve it across the shared HTTP retry loopaction_invocationsprimary key before placement/provider dispatch, snapshotting the original handler and node identity for later replayRegression contract
The engine tests send concurrent same-key registered-action and built-in
spawnrequests, force KV result writes to fail, and assert oneinvocation_id, one database row, one provideraction.invokeframe, one spawn capacity reservation, and the same non-null spawn handler node on both responses. A reordered-but-equivalent JSON input replays while a different input returns 409. Re-registering an action to a replacement handler cannot rewrite the original invocation's handler or node identity, including the post-provider-send/pre-dispatch-persistence race. The SDK test loses the first transport response and asserts both fetch attempts carry the same generated standard and compatibility headers.Verification
git diff --checkAtomicity note
The scoped key is hashed into a deterministic invocation id. The engine inserts that
action_invocationsprimary-key claim withON CONFLICT DO NOTHINGbefore any provider dispatch; concurrent requests and later retries replay the winning row, so this route no longer depends on a post-dispatch KV result write. The invocation row snapshots its original handler agent without a foreign key so a later action takeover or handler deletion cannot rewrite replay identity, and snapshots the selected handler node before the provider can observe its frame. Native-spawn placement is persisted immediately after capacity selection; a replay in the D1 write interval waits for that snapshot rather than returning a null target. Invocation lifecycle fields can still advance after the initial 201 (for example, takeover correctly fails an in-flight invocation). The deliberate at-most-once trade-off is that an isolate death after the durable claim but before placement/dispatch can leave a pending invocation and retries return a retryable error rather than permit the provider to execute twice.
