+# Proposal: Dockerized Bash Sandbox for Dashback Agent Tools
+
+## 1. Overview & Motivation
+
+Dashback currently equips LLM agents with code execution capabilities via `javascript.js` running inside a Node.js `worker_threads` VM with a virtualized file system (`vfs.js`). While effective for lightweight JavaScript transformations, this approach has limitations:
+
+1. **Language & Tooling Constraints:** Agents are restricted to JavaScript. They cannot run shell scripts, Python, `jq`, `ripgrep`, `git`, or standard command-line tools.
+2. **Isolation Boundaries:** Worker threads share host process memory and kernel resources. A native or non-VM shell tool running directly on the host would pose severe security and privilege escalation risks.
+3. **Reproducibility:** A containerized environment guarantees identical toolchain versions and execution environments across development and production deployments.
+
+This proposal specifies an isolated, container-based **Bash Tool** (`bash.js`) powered by a lightweight Docker image with sandboxed access to the company's virtual file system (VFS).

+```
+
+---
+
+## 4. Security & Runtime Constraints
+
+Containers must never be invoked with default privileged parameters. The runner applies strict Linux namespace and cgroup boundaries:
+
+| Flag | Rationale |
+| :--- | :--- |
+| `--user 1000:1000` | Executes strictly as unprivileged user `agent`. Matches UID with host file permissions. |
+| `--cap-drop=ALL` | Drops all Linux capabilities (prevents raw network creation, kernel module loading, chroot, ptrace). |
+| `--security-opt=no-new-privileges:true` | Disallows gaining privileges via `setuid`/`setgid` binaries. |
+| `--read-only` | The root filesystem is mounted read-only. The container cannot modify OS binaries, libraries, or configs. |
+| `--tmpfs /tmp:rw,nosuid,nodev,size=64m` | Provides a volatile, memory-backed scratch space with `nosuid` and `nodev`. |
+| `--tmpfs /home/agent/.cache:rw,nosuid,size=64m` | Allows tools like npm or python to write temporary caches without disk persistence. |
+| `--pids-limit 100` | Protects host from fork bombs (`:(){ :|:& };:`). |
+| `--memory 512m` | Caps RAM usage; terminates process if memory leaks or runaway allocations occur. |
+| `--cpus 1.0` | Restricts CPU usage to a single core equivalent to avoid CPU starvation. |
+| `--network none` | Prevents unauthorized external data exfiltration by default (can be bridged if specifically required). |
+| `-v <vfs_root>:/home/agent/workspace:rw` | Restricts file access solely to the company's workspace directory. |
+
+---
+
+## 5. Integration with Dashback
+
+### 5.1 VFS Lifecycle
+
+Each execution turn synchronizes through the existing Dashback VFS pipeline:
+
+1. **Preparation:**
+   ```javascript
+   const vfsRoot = await resolveVfsRoot(googleAuthId);
+   await prepareVfs(googleAuthId); // Hydrates files from `modelvfs` table
+   ```
+2. **Mounting:**
+   The directory `data/vfs/<companyId>` on the host is mounted to `/home/agent/workspace` inside the container.
+3. **Execution:**
+   Command is executed with a hard timeout (e.g. default 30s, max 120s).
+4. **Synchronization:**
+   ```javascript
+   await syncVfsToDb(googleAuthId); // Syncs any new or edited files back to `modelvfs`
+   ```
+
+### 5.2 Tool Implementation (`src/tools/bash.js`)
+
+```javascript
+import { execFile } from 'node:child_process';
+import { promisify } from 'node:util';
+import path from 'node:path';
+import { defineTool, ToolError } from 'libllmorbiter';

+## 6. Execution Models: Ephemeral vs. Persistent Daemon
+
+| Consideration | Ephemeral (`docker run --rm`) | Persistent Container (`docker exec`) |
+| :--- | :--- | :--- |
+| **Startup Overhead** | ~200–400ms per command | ~20–50ms per command |
+| **State Cleanliness** | Completely fresh OS environment every call | Processes/background jobs remain running |
+| **Lifecycle Complexity** | None. Docker handles lifecycle and cleanup | Requires container pool management and reaper |
+| **Failure Recovery** | Automatic | If container crashes, must be recreated |
+| **Recommendation** | **Adopt for Phase 1** | Evaluate if high execution frequency warrants it |
+
+---
+
+## 7. Implementation Roadmap
+
+1. **Phase 1: Docker Setup & Scripting**
+   - Add `docker/sandbox/Dockerfile`.
+   - Add build script: `npm run docker:sandbox:build` to `package.json`.
+   - Verify image build and base tools (`node -v`, `python3 --version`, `rg --version`, `jq --version`).
+2. **Phase 2: Bash Tool Implementation**
+   - Create `src/tools/bash.js` conforming to `defineTool`.
+   - Integrate with `prepareVfs` and `syncVfsToDb`.
+   - Add unit tests validating command execution, timeouts, and file synchronization.
+3. **Phase 3: Integration into Tool Registries**
+   - Register `createBashTool` in the agent execution registry alongside existing tools (`javascript.js`, `read-file.js`, `patch.js`).
+4. **Phase 4: Optional Network & API Bridge**
+   - If commands inside the container need to invoke Dashback endpoints (`http://host.docker.internal:4208/api`), introduce an opt-in network mode using Docker custom bridge networks with short-lived JWT tokens.

+     *       ### URL Format
+     *       Accepts:
+     *       - Relative VFS paths: `example.png`, `reports/summary.pdf`
+     *       - Full endpoint paths: `/vfs/example.png`, `/api/vfs/example.png` (leading `api/` and `vfs/` prefixes are automatically stripped)
+     *       - Absolute URLs: `https://.../api/vfs/example.png`
+     *       - Traversal (`..`), null bytes (`\0`), and backslashes (`\`) are strictly forbidden and rejected with HTTP 400.
+     *
+     *       ### Image Previews & Thumbnails
+     *       Supported raster images (`image/png`, `image/jpeg`, `image/gif`, `image/webp`, `image/avif`, `image/bmp`)
+     *       are automatically transformed into a **250×250 aspect-preserving preview thumbnail** (WebP format, quality 88):
+     *       - Scaled to fit within a 250×250 box without distortion (e.g. 2000×100 becomes 250×13).
+     *       - Images whose larger edge is below 100px are upscaled to 100px for icon legibility.
+     *       - A translucent dark metadata strip (`#101317`, max 50% height) with monospace text (`DejaVu Sans Mono`)
+     *         is rendered along the bottom edge, displaying original dimensions and file size.
+     *       - Served with `Content-Security-Policy: default-src 'none'; sandbox`.
+     *       - Use `?raw=1` (or `?raw=true`) to bypass preview generation and return the original unmodified image inline.
+     *
+     *       ### Inline vs Attachment
+     *       - Browser-compatible types (HTML, CSS, JS, JSON, PDF, text, images, audio, video, fonts, WASM)
+     *         are served with `Content-Disposition: inline; filename="..."` so they open directly in modern browsers.
+     *       - Non-browser/binary types default to `Content-Disposition: attachment; filename="..."`.
+     *       - Use `?download=1` (or `?download=true`) to force file download with `Content-Disposition: attachment`.
+     *
+     *       ### Caching & Conditional Requests
+     *       - Generates weak ETags (`W/"thumb-..."` for previews, `W/"<timestamp>-<mode>"` for originals).
+     *       - Sets `Cache-Control: private, max-age=0, must-revalidate`.
+     *       - Supports `If-None-Match` conditional requests returning HTTP `304 Not Modified`.
