### structure under $HOME/.claude folder
- ide: live claude process, filename pattern `$pid.lock`
- projects: store each projects message list
- statsig: unknown
- todos: unknown

### project directory name

```
// (pseudocode reconstructed from the bundled file)
const projectRoot = path.join(os.homedir(), '.claude', 'projects');
const key = cwd                      // e.g.  /Users/kaichen/workspace/claco
  .replace(/^\/+/, '')               // drop leading “/”
  .replace(/[\\/:]+/g, '-')          // → Users-kaichen-workspace-claco
  .replace(/^-+|-+$/g, '');          // trim extra dashes
const projectDir = path.join(projectRoot, key);
fs.mkdirSync(projectDir, {recursive:true});
```

### project jsonl log

```
const logfile = path.join(projectDir, `${sessionId}.jsonl`);
const stream  = fs.createWriteStream(logfile, {flags:'a'});
const record = {
  parentUuid,            // threading / follow-up
  isSidechain,           // true when spawned by an Agent tool
  userType,              // 'external' | 'assistant' | 'system'
  cwd,                   // absolute working directory
  sessionId,             // same UUID as filename
  version: pkg.version,  // CLI version
  type,                  // 'user' | 'assistant' | 'system'
  message,               // full Anthropic message object
  uuid: crypto.randomUUID(),
  timestamp: new Date().toISOString()
};
stream.write(JSON.stringify(record) + '\n');
```
