# Scheduler Bridge

> JS-side interface to the Kotlin AlarmManager native module.

# Scheduler Bridge

The Scheduler Bridge (lib/scheduler.ts) is the JavaScript-side interface to the Kotlin scheduler-module native module. It translates task instance data from SQLite into hardware alarm registrations on Android.

***

## Core Function

```typescript theme={null}
export async function scheduleNextAlarm(): Promise<void>
```

This function:

1. Queries task\_instances from SQLite for upcoming pending instances
2. Serializes the instance data into a JSON payload
3. Passes it to the Kotlin SchedulerModule via the native bridge
4. The Kotlin module registers exact alarms via AlarmManager.setExactAndAllowWhileIdle()

***

## When It Runs

The scheduler bridge is called as Step 3 of the Triple-Write Orchestrator. It also runs during:

* HydrationSync completion (after delta ingestion)
* Manual Resync (after database rebuild)
* Cold boot (via the Kotlin Boot Receiver)
