# Contributing

Thanks for your interest in contributing to this project.

## Scope

This repository is documentation-first. Contributions are welcome for:
- clarity and consistency improvements
- framework test cases and validation protocols
- translation and editorial quality
- issue reproduction and version diffs

## Before You Open a PR

1. Read `README.md` and `INDEX.md`
2. Confirm whether the target file is canonical or legacy
3. Open an issue for significant structural or ontological changes

## Contribution Rules

- Keep released versioned files stable; a change of substance ships as a new edition; a wording patch is applied in place with a dated patch note
- Update by addition; a full rewrite becomes a new versioned file
- Add clear rationale for any change in epistemic rules
- State behaviour claims as observed, reproducible behaviour, with the example that reproduces them

## Commit and PR Guidance

- One topic per PR
- Clear title: `module: short summary`
- Include:
  - what changed
  - why
  - compatibility impact
  - validation method

## Documentation Style

- Keep section numbering consistent with existing files
- Preserve bilingual style where already used
- Define each term explicitly; a metaphor illustrates a definition already given
