 - 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.
 - 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 `$CLINE_DIR/hooks` with `~/.cline/hooks` as the default; keep Documents and workspace hook roots read-only. Use supported event filenames, preserve official hook input byte-for-byte, use `process.execPath` in Node and Go wrappers, and resolve Python runtimes from absolute shebangs. Translate guard exit code `2` into JSON stdout with `cancel: true`. Treat hook errors, timeouts, and invalid control JSON as fail-open.
+- Model Codex JSON files, inline TOML layers, managed `requirements.toml`, and plugin-bundled hooks as additive stable sources. SDK adapters write only `~/.codex/hooks.json`, preserve project and managed sources, retain the three-level matcher contract, and require `/hooks` trust review for changed user hooks.
 - Write GitHub Copilot CLI hooks only to `$COPILOT_HOME/hooks/elydora-audit.json` with `~/.copilot/hooks/elydora-audit.json` as the default. Migrate exact Elydora-owned entries from project `.github/hooks/hooks.json`, preserve native camelCase input, require `disableAllHooks` to be false, and commit runtime plus hook documents in one rollback-capable transaction.
 - Model Cursor as one CLI-and-IDE hook contract. Preserve user, project, and enterprise sources in documented priority order; forward `tool_name`, `tool_input`, and `conversation_id`; use exit code `2` for denial; record `failClosed` as the per-script failure-mode control.
 - Write Node Cursor hooks only to `~/.cursor/hooks.json`; keep project and enterprise sources read-only. Register `preToolUse`, `postToolUse`, and `postToolUseFailure`, preserve the complete native payload, emit valid native JSON responses, retain PowerShell exit codes, and commit guard, runtime metadata, private key, audit runtime, and user hooks in one rollback-capable transaction.
