## Description

MANDATORY for every coding agent (Claude Code, Codex, or any other) on every change-set, every applicable source file the agent creates or updates MUST start with the project's copyright/authorship header (file overview + exact author line). Use automatically whenever writing a new file or editing an existing one; do not wait to be asked. Covers JS/TS/TSX/CJS/MJS, Python, shell, and CSS. Includes the audit script to verify repo-wide compliance.

# File Headers, Copyright Comment + File Overview

Every applicable source file in this repository starts with a header comment
containing a **file overview** and the **exact author line**:

```
@author Son Nguyen <hoangson091104@gmail.com>
```

The name and email must be exactly as above, no variations, no substitutions,
no other names. This applies to **every coding agent** working in this repo
(Claude Code, Codex, or any other tool): when you **create** a new applicable
file, write the header first; when you **update** an existing applicable file
that is missing the header, add it as part of the same change.

## Applicable files

| Included | Excluded |
| -------- | -------- |
| `*.js`, `*.ts`, `*.tsx`, `*.cjs`, `*.mjs` | anything under `node_modules/`, `dist/`, `build/`, `data/`, `.worktrees/` |
| `*.py`, `*.sh` | vendored/minified files (`*.min.js`, `wiki/mermaid.min.js`) |
| `*.css` | generated files (`wiki/i18n-content.js`, carries its own AUTO-GENERATED banner) |
| | snapshots (`__snapshots__/`), lockfiles, JSON/YAML/Markdown |

## Header formats by file type

**JS / TS / TSX, server & scripts style** (overview inline in `@file`):

```js
/**
 * @file One-to-few-sentence overview of what this file does and why it
 * exists. Mention the key contracts or invariants the file owns.
 * @author Son Nguyen <hoangson091104@gmail.com>
 */
```

**JS / TS / TSX, client style** (`@file` name + `@description` overview), used
under `client/src/`:

```ts
/**
 * @file ComponentName.tsx
 * @description What the component/module renders or provides and how it fits
 * into the app.
 * @author Son Nguyen <hoangson091104@gmail.com>
 */
```

**CSS** (same block-comment shape as `client/src/index.css`):

```css
/**
 * @file file.css
 * @description What these styles cover.
 * @author Son Nguyen <hoangson091104@gmail.com>
 */
```

**Shell** (`#` block right after the shebang; existing overview comments count, just make sure the `@author` line is in the block):
