packages/core/src/session/recovery.ts defines BATCH_SIZE = 100 and contains separate recovery handling for claimed executions, pending recovery wakes, and ordinary session wakes; recovery work is ordered by SessionRecoveryTable.time_created then SessionRecoveryTable.execution_id.packages/core/src/session/recovery.ts checks ownership against both execution ID and owner ID before processing a claim, recognizes execution phases "safe", "unknown", and "continue", publishes recovery events through EventV2, and logs failures as "Failed to recover Session" with the associated cause.SessionRecoveryTable.wake_pending = true, uses compare-and-set conditions including the current wake_attempts, and processes ordinary session wakes in two groups: retries with wake_attempts > 0 through MAX_WAKE_ATTEMPTS, followed by fresh ordinary wakes up to the remaining capacity in BATCH_SIZE.packages/core/src/session/execution/local.ts implements current-process routing for implicit-local locations and explicitly leaves future remote placement at this abstraction boundary.SessionExecutionLocal.make() creates one process-wide ownerID using crypto.randomUUID(), converts SESSION_EXECUTION_LEASE_MS with Duration.toMillis(...), tracks active claims in Map<SessionSchema.ID, SessionExecutionClaim.Claim>, and constructs a SessionRunCoordinator.SessionExecutionLocal drain, each run gets a new executionID from crypto.randomUUID() and attempts to insert SessionExecutionTable values { id, session_id, owner_id, phase: "ready", time_created: now, expires_at: now + leaseDuration } using .onConflictDoNothing(); if another execution already owns the session, the drain returns without running.packages/core/src/session/execution/local.ts finds the oldest eligible SessionRecoveryTable row for the session where wake_pending = true and recovery_error IS NULL, ordered by time_created and execution_id; it passes that row’s continuation_message_id to input.run(claim, force, recoveryInputID).input.run(...) against repeated SessionExecutionClaim.update(db, claim) lease renewal scheduled every leaseDuration / 3 milliseconds via Schedule.spaced(...). Non-interruption-only drain failures are logged as "Failed to drain Session" and annotated with sessionID.activeClaims. Successful runs clear the claim. For failures, the code reloads the current phase by matching session_id, execution id, and owner_id; an interrupted execution is retained unless its phase is "safe", while claims in phases other than "unknown" and "continue" are cleared.SessionExecutionLocal exposes active: coordinator.active, resume: coordinator.run, and wake: coordinator.wake. Its interrupt(sessionID) falls back to coordinator.interrupt(sessionID) when no local active claim exists.packages/core/src/session/execution/local.ts first renews it, forks scoped lease renewal every leaseDuration / 3, then calls coordinator.interrupt(...) with claim clearing as the completion action. If clearing defects with SessionExecutionClaim.Lost, the defect is tolerated only when no current SessionExecutionTable row remains for that session; otherwise it is rethrown.SessionExecutionLocal layer obtains SessionStore.Service and LocationServiceMap.Service; its runner loads the session, dies with Session not found: ${claim.sessionID} when absent, and invokes runner.run({ ...claim, force, recoveryInputID }) under the service layer selected by locations.get(session.location).SessionExecutionLocal.node is created with makeGlobalNode(...) for SessionExecution.Service; dependencies are exactly [Database.node, SessionStore.node, LocationServiceMap.node]. The module self-exports as SessionExecutionLocal via export * as SessionExecutionLocal from "./local".continuation and message from ./recovery-id, defines an input contract containing executionID: Schema.String, and includes recovery-aware projection, promotion, commit, and wake behavior.projectAdmitted, promoteNextQueued, and promoteExact. Recovery validation can fail with exact reasons "Invalid recovery projection identity" and, through a defect path, persists defect.reason into SessionRecoveryTable.recovery_error.SessionMessageTable.id = recovery.assistant_message_id, can construct a synthetic recovery projection, validates projection identity and promotion state, and uses exact matching on session_id, message ID, and promotion-related fields before committing or promoting an input.
