On successful completion with pendingWake, it clears pendingWake and starts a non-forced successor on the same entry. Otherwise it either removes the key or replaces the entry with a new successor, then completes entry.done with the original exit.run-coordinator.ts:72-84 implements run() under Effect.uninterruptibleMask: if an entry is active and stopping, callers await entry.done and retry run(key); if active and not stopping, callers join by awaiting the same done; if idle, it creates an entry and starts drain(key, true).run-coordinator.ts:86-97 implements wake(): an active entry gets pendingWake = true, coalescing repeated wakeups; an idle key gets a new entry and starts drain(key, false).run-coordinator.ts:99-123 implements interrupt(): if no owned fiber exists it only runs cleanup; otherwise it sets stopping = true, clears pendingWake, interrupts the owner, runs cleanup, verifies the same entry still owns the key, requires the interrupted execution to have settled, and either deletes the entry or starts a successor if work became pending during stopping.interrupt() throws new Error("Interrupted Session execution did not settle") if the owner interruption completes without entry.exit being recorded.packages/core/src/event.ts:80-107 reads durable aggregate events where aggregate_id matches, seq > after, and event type appears in the manifest; it orders by ascending EventTable.seq, fetches input.limit + 1, decodes only the first input.limit rows, and reports hasMore: rows.length > input.limit.packages/core/src/event.ts maps each row to id, a manifest-resolved event type, durable.aggregateID, durable.seq, the manifest definition’s optional durable version, and data.packages/core/src/event.ts:110-113 defines SubscriberOverflowError as Schema.TaggedErrorClass with tag "EventV2.SubscriberOverflow" and integer field capacity.PublishOptions in packages/core/src/event.ts supports optional id, metadata: Record<string, unknown>, location: Location.Ref, and commit(seq). The commit callback is documented as a local operational projection committed atomically with a new durable event and is neither replayed nor serialized.Event.Interface exposes publish, typed subscribe, all, aggregate-specific durable, deprecated listen, project, replay, replayAll, remove, and claim; replay/replayAll accept optional publish, ownerID, and strictOwner, while claim(aggregateID, ownerID) assigns ownership.packages/core/src/event.ts:152-164 function allBounded(events, capacity) creates Queue.dropping<Payload, SubscriberOverflowError>(capacity), subscribes via deprecated events.listen, fails the queue with new SubscriberOverflowError({ capacity }) when Queue.offer rejects an event, registers a finalizer that unsubscribes and shuts down the queue, and returns Stream.fromQueue(queue).Event.layerWith(options?) accepts LayerOptions.beforeAggregateRead?: (aggregateID: string) => Effect.Effect<void> and initializes unbounded all-event pubsub, per-aggregate durable subscriber sets, typed pubsubs, type-keyed projector arrays, and a listener array.Event.layerWith() helper getOrCreate(definition) reuses pubsub.typed.get(definition.type) or creates and caches a new PubSub.unbounded<Payload>(); an adjacent TODO says durable projectors must be bound to exact type and version before incompatible historical payloads are supported.
