# ADR-0005: Use Independent Worker Processes And NDJSON IPC
|
|
|
|
- Status: Accepted

|
## Context
|
|
|
|
A single agent process doing all work would cause context explosion, reduce responsiveness, and make parallel execution fragile. AirCoding needs workers that can be monitored, retried, cancelled, and recovered independently.
|
|
|
|
## Decision
|
|
|
|
Run Executor, Reviewer, Debugger, Compactor, and ExperienceMiner as independent Bun child processes. Use NDJSON over stdio for IPC.
|
|
|
|
IPC messages use:
|
|
|
|
```text
|
|
kind: event
|
|
kind: control
|
|
kind: log
|
|
```
|
|
|
|
The Scheduler owns process lifecycle, heartbeat monitoring, timeout handling, and WorkerResult collection.
|
|
|
|
## Consequences
|
|
|
|
- Main Agent remains responsive.
|
|
- Workers have bounded task context.
|
|
- Scheduler can detect lost workers through heartbeat/process state.
|
|
- stdout is reserved for protocol; stderr is crash/fatal fallback.
|
|
- Worker loops may be role-specific rather than one generic shared loop.
