+## Tree View of Loaded Context Files
+- **Global:** `/home/rwolf/.gemini/GEMINI.md`
+- **Project:** (None found)
+
+## Active Directives
+
+### Global Directives (from `~/.gemini/GEMINI.md`)
+
+#### Auto-Documentation
+- At the beginning of every session in a project, create or refresh a `directives.md` file in the project root.
+- Include a **Tree View** showing the hierarchy of loaded context files (e.g., Global -> Project -> JIT).
+- Include a **Mermaid Flow Diagram** illustrating the inheritance and precedence of these directives.
+- This file must contain the concatenated set of active directives (Global, Project, and any JIT contexts).
+
+#### Scripting Standards
+- **Shell:** Default to Bash (version 4.0+) unless a specific environment requires POSIX `sh`.
+- **Safety First:** Always include `set -euo pipefail` at the top of executable scripts to ensure they fail fast on errors.
+- **Documentation:** Every script should include a usage function and basic header comments explaining its purpose and dependencies.
+- **Dependencies:** Check for required tools (e.g., `jq`, `curl`, `ffmpeg`) at the start of the script and provide clear error messages if they are missing.
+
+#### Interaction Preferences
+- **Non-Interactive Execution:** When running `gemini` commands from within a script or this CLI, always use the `-p` flag to avoid recursive interactive sessions.
+- **Subscription Awareness:** I am using a Google One AI Pro subscription; leverage the higher quotas and capabilities of the Gemini 1.5 Pro/Ultra models when appropriate.
+- **Surgical Edits:** When modifying existing scripts, use the `replace` tool for precise updates rather than overwriting entire files unless a full refactor is requested.
+- **Testing:** For new scripts or major changes, propose a simple test case or a way to verify the functionality safely.

+# OpenWolf Security Audit & Patches - May 2026
+
+This document summarizes the security vulnerabilities identified and patched in the OpenWolf codebase.
+
+## Vulnerabilities Fixed
+
+### 1. Command Injection in CLI (Critical)
+*   **Vulnerability:** Unsanitized project paths and daemon names were passed directly to `execSync` string templates.
+*   **Impact:** Arbitrary code execution if a project was placed in a directory with shell metacharacters (e.g., ``my-project`; rm -rf /`).
+*   **Fix:** Replaced `execSync` with `execFileSync` using array-based arguments in `src/cli/daemon-cmd.ts` and `src/cli/init.ts`. This prevents shell interpolation of arguments.
+*   **Verification:** Verified via `tests/security.test.ts` ensuring metacharacters are handled as literal strings.
+
+### 2. Lack of Authentication & Information Disclosure (High)
+*   **Vulnerability:** The dashboard server (Express + WebSocket) had no authentication and was exposed on all network interfaces.
+*   **Impact:** Unauthorized access to project metadata, file contents in `.wolf/`, and the ability to trigger cron tasks by anyone on the network.
+*   **Fix:**
+    *   Explicitly bound the Express server to `127.0.0.1` in `src/daemon/wolf-daemon.ts`.
+    *   Implemented session-based token authentication. A secure token is generated on startup and saved to `.wolf/daemon-token.tmp`.
+    *   Added middleware to require the token for all API and WebSocket connections.
+    *   Updated the CLI to automatically pass the token when opening the dashboard.
+*   **Verification:** Verified explicit binding and unauthorized access rejection in test suite.
+
+### 3. Path Traversal in Cron Engine (Medium)
+*   **Vulnerability:** The `ai_task` action in `CronEngine` blindly joined file paths, allowing reads outside the project root.
+*   **Impact:** Potential disclosure of sensitive system files (e.g., `/etc/passwd`) if `cron-manifest.json` was manipulated.
+*   **Fix:** Added path resolution and prefix validation in `src/daemon/cron-engine.ts` to ensure all context files stay within the project root.
+*   **Verification:** Verified that `../` paths are blocked in `tests/security.test.ts`.
+
+### 4. Denial of Service in File Watcher (Low)
+*   **Vulnerability:** The file watcher broadcasted full contents of changed files regardless of size.
+*   **Impact:** Memory exhaustion or network congestion when handling large files.
+*   **Fix:** Enforced a 1MB limit in `src/daemon/file-watcher.ts`. Files larger than this are logged but not broadcasted.
+*   **Verification:** Verified size limit logic in test suite.
+
+## Verification
+A new automated test harness was added:
+*   **Test Runner:** Node.js native (`node:test`)
+*   **Command:** `npm test`
+*   **Results:** 4/4 security tests passing.
