 - Keep Grok Build writes inside its native global `$GROK_HOME/hooks/*.json` contract. Treat Claude Code and Cursor compatibility files plus project `.grok/hooks` as read-only integration sources.
 - Write Auggie hooks only to `~/.augment/settings.json`; keep system and workspace settings read-only. Generate `.cmd` wrappers on Windows and `.sh` wrappers on Unix because Auggie dispatches supported script paths, and express hook timeouts in milliseconds.
 - Write Cline hooks only to `$CLINE_DIR/hooks` with `~/.cline/hooks` as the default; keep Documents and workspace hook roots read-only. Translate guard exit code `2` into Cline's JSON stdout cancellation control and preserve official hook input byte-for-byte.
+- 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 and require `/hooks` review after external changes.
