# Signal Handling Application Guide

**Status**: 📋 Planned - Coming in Crucible v0.2.4

**Audience**: Application developers using gofulmen, pyfulmen, or tsfulmen helper libraries.

**Purpose**: Standardized signal handling patterns for graceful shutdown, configuration reload, and runtime control across the Fulmen ecosystem.

---

## Planned Coverage

- **Graceful Shutdown**: SIGTERM/SIGINT handling with connection draining
- **Configuration Reload**: SIGHUP handling for live config updates
- **Runtime Control**: SIGUSR1/SIGUSR2 for application-specific signals
- **Multi-Platform**: Unix/Linux/Windows signal handling differences
- **Testing Patterns**: Testing signal handlers in CI/CD
- **Observability**: Tracking signal-driven termination in telemetry

---

## Related Standards

- **Exit Codes**: See `docs/standards/fulmen/exit-codes/README.md` for signal exit codes (128+N pattern)
- **Application Identity**: See `docs/standards/fulmen/identity/README.md` for graceful shutdown coordination

---

**Coming Soon**: Full implementation guide with language-specific examples and helper library integration patterns.

**Track Progress**: [Crucible Issue #TBD]
