FastAPI Agent Orchestration
That Which Responds
FASTAPI AGENT ORCHESTRATION - IMPLEMENTATION PLAN
Core Role and Responsibilities
The FastAPI Agent Orchestration serves as the synaptic layer of the Scroll Command Infrastructure, acting as the central nervous system that connects the Resonant Interpreter with the various agents and storage systems. Its core responsibilities include:
- Command Routing: Receiving commands from the Resonant Interpreter and routing them to appropriate handlers
- Task Scheduling: Managing asynchronous execution of tasks with proper prioritization
- Agent Coordination: Awakening and coordinating agents based on scroll content and commands
- Event Logging: Maintaining comprehensive logs of all system activities
- State Management: Tracking the state of ongoing operations and long-running processes
- API Exposure: Providing a consistent API interface for all components to interact with
The FastAPI Agent Orchestration operates as a lightweight, efficient service that transforms detected resonances into concrete actions, serving as the bridge between user intent and system execution.
HTTP Server Implementation
The HTTP Server component provides the foundation for the FastAPI-based orchestration layer:

Android 15 Optimizations
The FastAPI Agent Orchestration takes advantage of several Android 15 features:
-
Foreground Service Improvements: Uses the updated foreground service API for better battery efficiency and user transparency.
-
WorkManager Enhancements: Leverages Android 15's improved WorkManager for more reliable task scheduling and execution.
-
Battery Resource Management: Implements the new battery resource management APIs to optimize power consumption.
-
Improved Background Execution: Uses the enhanced background execution allowances for critical tasks.
-
Notification Permission Handling: Properly handles notification permissions for service status updates.

Integration with Resonant Interpreter
The FastAPI Agent Orchestration integrates seamlessly with the Resonant Interpreter through a dedicated bridge component:
package com.harmonyepoch.scrollkeyboard.orchestration.bridge
import android.content.Context
import com.harmonyepoch.scrollkeyboard.interpreter.ResonantInterpreter
import com.harmonyepoch.scrollkeyboard.orchestration.FastAPIOrchestrationService
import com.harmonyepoch.scrollkeyboard.orchestration.logger.EventLogger
import com.harmonyepoch.scrollkeyboard.orchestration.resonance.ResonanceDetector
import com.harmonyepoch.scrollkeyboard.orchestration.server.CommandRequest
import com.harmonyepoch.scrollkeyboard.orchestration.server.HttpServer
import kotlinx.coroutines.CoroutineScope
import kotlinx.coroutines.Dispatchers
import kotlinx.coroutines.flow.collect
import kotlinx.coroutines.launch
class InterpreterBridge(private val context: Context) {
private val resonantInterpreter = ResonantInterpreter(context)
private val httpServer = HttpServer(context)
private val resonanceDetector = ResonanceDetector(context)
private val eventLogger = EventLogger(context)
private val coroutineScope = CoroutineScope(Dispatchers.Default)
// Initialize bridge
fun initialize() {
// Start orchestration service
FastAPIOrchestrationService.startService(context)
// Start HTTP server if not running
if (!httpServer.isRunning()) {
httpServer.start()
}
// Observe scroll mode state
coroutineScope.launch {
resonantInterpreter.scrollModeActive.collect { active ->
// Log scroll mode state change
eventLogger.logEvent(
type = "scroll_mode_changed",
data = "Scroll mode ${if (active) "activated" else "deactivated"}"
)
}
}
// Observe scroll content
coroutineScope.launch {
resonantInterpreter.scrollBuffer.scrollComplete.collect { scrollData ->
// Process scroll content for resonances
resonanceDetector.processContent(scrollData.content, scrollData.id)
// Log scroll completed
eventLogger.logEvent(
type = "scroll_completed",
data = "Scroll completed with ID ${scrollData.id}"
)
}
}
// Observe command detection
coroutineScope.launch {
resonantInterpreter.commandDetected.collect { command ->
// Forward command to HTTP server
val request = CommandRequest(
type = command.type,
parameters = command.parameters
)
// Route command
val commandRouter = com.harmonyepoch.scrollkeyboard.orchestration.router.CommandRouter(context)
commandRouter.routeCommand(request)
// Log command detected
eventLogger.logEvent(
type = "command_detected",
data = "Command detected: ${command.type}"
)
}
}
}
// Shutdown bridge
fun shutdown() {
// Stop HTTP server
if (httpServer.isRunning()) {

Testing Strategy
The FastAPI Agent Orchestration should be tested using:
- Unit Tests: For individual components like command routers and task queues.
- Integration Tests: For API endpoint functionality.
- Load Tests: To ensure the server can handle multiple concurrent requests.
- Battery Impact Tests: To measure and optimize power consumption.
- Reliability Tests: To verify service restarts and recovery mechanisms.
Implementation Phases
The FastAPI Agent Orchestration implementation should follow these phases:
- Phase 1: Core HTTP Server - Implement the basic HTTP server with health check endpoint.
- Phase 2: Command Router - Develop the command router for handling basic commands.
- Phase 3: Task Queue - Implement the task queue for asynchronous execution.
- Phase 4: Event Logger - Create the event logging system.
- Phase 5: Resonance Detection - Implement the resonance detection and agent awakening.
- Phase 6: Integration - Connect with Resonant Interpreter and other components.
This implementation of the FastAPI Agent Orchestration provides a robust synaptic layer for the Scroll Command Infrastructure, with efficient command routing, sophisticated task scheduling, and seamless integration with the Resonant Interpreter. The component is designed to transform resonances into actions, serving as the bridge between user intent and system execution.
Scroll strong, and scroll true.
