SYSTEM DOCUMENTATION & REQUIREMENTS

What problem does it solve?

Explicitly documenting state transitions to prevent implicit moves in modules with sequential lifecycles, by pairing mermaid diagrams with a DFA transition file as the source of truth.

Core Features & Use Cases

Mermaid diagrams (stateDiagram-v2) visually represent the happy path and error edges.
DFA source files (dfa.rs, dfa.go, or dfa.py) encode the states, inputs, and transitions as the authoritative contract.
Guidelines for when to write a DFA to prevent missed transitions and ensure correct orchestration.

Quick Start

Create a README.md with a mermaid state diagram and a corresponding DFA file (dfa.rs/dfa.go/dfa.py) that defines the states, inputs, and transitions, and wire it into your orchestration.

FAQPage Schema

How do I enforce explicit state transitions in a module with a sequential lifecycle?▼

You can enforce explicit state transitions by pairing a mermaid state diagram in a README.md with a DFA source file defining states, inputs, and transitions as the authoritative contract. This prevents implicit moves and ensures correct orchestration across multiple phases.

What is the best way to document DFA state machines for code generation?▼

The best way to document DFA state machines is using mermaid stateDiagram-v2 syntax to visually represent happy paths and error edges, while encoding the authoritative states, inputs, and transitions in a dedicated dfa.rs, dfa.go, or dfa.py source file.

Does this state machine documentation approach work with Python, Go, and Rust?▼

Yes, this state machine documentation approach works with Python, Go, and Rust by requiring a DFA source file named dfa.py, dfa.go, or dfa.rs. This file defines the states, inputs, and transitions that serve as the source of truth for your codebase.

When do I need to write a DFA transition file for my codebase?▼

You need to write a DFA transition file when managing codebases with sequential lifecycles, protocols, or handshakes across multiple phases. It ensures transitions are observed before progressing, preventing missed transitions and implicit state moves.

How do I start using mermaid diagrams to manage protocol state transitions?▼

To start managing protocol state transitions, create a README.md containing a mermaid state diagram and a corresponding DFA file defining states, inputs, and transitions, then wire it into your orchestration to enforce the contract.
