# ChronoSeal Design Philosophy

**"Files as a Software" (FaaS) — Everything is a file.**

ChronoSeal is intentionally designed as a **first-class citizen of Linux**. The entire application behaves as if it is a well-designed native file in the Unix filesystem.

### Core Beliefs

- The CLI is the single source of truth.
- The application must be controllable, inspectable, configurable, and composable using standard Unix tools.
- Any GUI, TUI, or web interface is only a thin wrapper.
- Production robustness and decades-long maintainability take precedence over rapid development.

### Key Principles Applied

- **Behave like a file**: Clear interface, predictable behavior, proper lifecycle (open/read/write/close semantics via signals and commands).
- **Composability**: Works naturally with pipes, redirection, systemd, scripts, and orchestration tools.
- **Observability**: Everything important is exposed as text or structured data.
- **Minimal Friction**: One-line installer, excellent `--help`, proper man pages.
- **Respect for the OS**: Follows FHS, XDG, systemd best practices, and hardened security model.

This philosophy guided the complete refactoring of ChronoSeal.

**Status**: Core architecture and systemd integration completed. Rich CLI, configuration system, and installer are in progress.
