 - Validate Auggie matcher syntax during installation with Node.js `new RegExp`; keep status and uninstall independent from the JavaScript validator so recovery remains available offline.
 - Write Cline file hooks to `$CLINE_DIR/hooks` with `~/.cline/hooks` as the default; keep Documents and workspace hook roots read-only. Use supported event filenames, preserve official hook input byte-for-byte, use `process.execPath` in Node and Go wrappers, and resolve Python runtimes from absolute shebangs. Translate guard exit code `2` into JSON stdout with `cancel: true`. Treat hook errors, timeouts, and invalid control JSON as fail-open.
 - Preserve Factory Droid's scope-root `hooks.json` precedence, legacy nested hook source, and per-event `settings.json` fallback. Scope-root and legacy files store event keys at the document root; settings stores the same map under `hooks`. Edit only effective user sources; keep project and organization sources read-only. Preserve JSONC comments through syntax-tree edits, use SDK-native absolute runtime commands, commit generated runtime artifacts and hook sources as one recoverable transaction, and require `/hooks` review after external changes.
+- Resolve Qwen Code user settings through explicit `QWEN_HOME`, then user-level `.qwen/.env`, then `~/.env`, with `~/.qwen/settings.json` as the default. Keep workspace settings read-only. Preserve JSON comments, reject trailing commas and duplicate keys before writes, express timeouts in milliseconds, propagate native exit code `2` through PowerShell, and require `/hooks` review.
