From acbcc293aa25239af1f02a3b7f3666b72c10467c Mon Sep 17 00:00:00 2001 From: bb-connor Date: Wed, 18 Feb 2026 11:20:53 -0500 Subject: [PATCH 01/23] =?UTF-8?q?feat(cua):=20CUA=20Gateway=20passes=20#7-?= =?UTF-8?q?#14=20=E2=80=94=20guards,=20rulesets,=20research,=20ecosystem?= =?UTF-8?q?=20integrations?= MIME-Version: 1.0 Content-Type: text/plain; charset=UTF-8 Content-Transfer-Encoding: 8bit Complete CUA (Computer-Use Agent) Gateway implementation across 14 research and execution passes. This adds runtime security enforcement for AI agents operating in remote desktop, browser automation, and input injection contexts. Rust: - 3 CUA guards: computer_use (observe/guardrail/fail_closed modes), remote_desktop_side_channel (per-channel enable/disable + transfer size), input_injection_capability (input type allowlist + postcondition probes) - 7 CUA event types in PolicyEventType including remote.session_share - CuaEventData struct with serde support and snake_case aliases - 3 built-in rulesets: remote-desktop, remote-desktop-strict, remote-desktop-permissive - Fail-closed fixes: deny missing input_type (C2), deny unknown side channels (C3) TypeScript: - CuaEventData interface + 7 EventType variants in adapter-core - 7 factory methods in PolicyEventFactory (including createCuaSessionShareEvent) - OpenClaw CUA bridge handler (283 lines) with 43 tests - 3 stable error codes (OCLAW_CUA_UNKNOWN_ACTION, MISSING_METADATA, SESSION_MISSING) Research & fixtures: - 9 deep-dive topic files, execution backlog, review log (14 passes) - 17 Python validation harnesses (130+ fixture checks) - 21 fixture groups across policy-events, receipts, and benchmarks - trycua/cua connector evaluation with compatibility matrix - Pass #14 code review report with 3 critical issues resolved CI: 17 roadmap harnesses run on every PR/push.

This document contains inline correction notes and verified source links, but still includes unresolved citation tokens from the original agent export. + +## Executive summary + +A “computer‑use agent gateway” (desktop/OS input + UI surface) is best designed as a **controlled UI runtime** plus a **policy‑enforcing mediation layer** that is the *only* way an agent can observe pixels and cause clicks/keystrokes. The most robust designs treat the gateway as the security boundary (not the agent) and make the runtime ephemeral and compartmentalized (container/microVM/VM), with receipts signed by a key protected by a hardware root of trust when possible. citeturn8search0turn8search4turn10search0turn16search2turn9search6 + +A high‑leverage MVP path is **browser‑first**—because browser automation already provides structured context (DOM + accessibility tree) and deterministic instrumentation APIs. The most mature ecosystem options center on **Playwright**, **Puppeteer**, and **Selenium/WebDriver** for action execution; **Chrome DevTools Protocol (CDP)** and **WebDriver BiDi** for low‑level telemetry/event streaming; and browser‑native screenshot/trace capture for receipts. citeturn18search4turn18search0turn0search3turn0search2turn18search5 + +For full desktop (Windows/macOS/Linux) “click around the OS” coverage, the practical gateway patterns are: + +- **Remote‑desktop‑mediated desktops** (VNC/RDP/WebRTC streaming), where the gateway is the one and only participant that speaks the protocol and enforces policy; and/or +- **Virtual display / headless compositor** approaches on Linux (Xvfb, Weston RDP backend, GNOME remote desktop) that run without physical GPU/input, simplifying containment and capture. citeturn2search4turn16search4turn4search0turn24search3turn24search2 + +For signed receipts, treat each action as an append‑only event with **hash‑chained evidence** (frame hashes + optional diffs + structured UI context) and produce signatures using (a) traditional keypairs (OpenSSL/libsodium) and/or (b) “keyless” or transparency‑log systems such as **Sigstore (cosign + Rekor)** for auditability and witnessability. citeturn12search0turn9search8turn9search16turn15search3turn15search13 + +When threat models include **malicious/compromised agents**, **host compromise**, and **insider threats**, the strongest practical posture is: isolate the UI runtime in a microVM/VM (Firecracker/KVM/QEMU/Hyper‑V/Apple Virtualization), keep signing keys out of the agent and (ideally) out of the host OS via TEEs/attestation (Nitro Enclaves / SGX / SEV‑SNP / TDX), and default to fail‑closed for sensitive actions (file exfil, credential entry, security settings changes). citeturn22search0turn8search3turn11search4turn10search0turn10search2turn10search3 + +## Reviewer annotations (2026-02-18) + +> REVIEW-CORRECTION: The `cite...`, `entity...`, and `image_group...` tokens are unresolved export artifacts and are not verifiable citations.

and policy tuning. + +**Guardrail** +- Allow low‑risk actions automatically; gate high‑risk actions behind approval or stronger assertions. +- Enforcement: policy engine returns `allow_with_constraints` (must match expected URL/frame hash) or `needs_approval`. +- A practical example: allow clicking navigation links within an allowlisted domain, but require approval for file uploads or password entry (because Guacamole and other RD stacks can support file transfer and clipboard, which are common exfil paths). citeturn2search8turn16search4 + +**Fail‑closed** +- Default

reduce implementation risk, define an adapter that maps CUA `computer.use` requests into existing policy events and guard checks: + +- Map navigation/network side effects into `egress_allowlist` checks. +- Map tool invocation and shell fallbacks into `mcp_tool`/command restrictions. +- Map file upload/download flows into `forbidden_path` and `secret_leak` checks. +- Emit audit events through existing hushd pathways so CUA and non-CUA decisions share the same SIEM surface. +- Add a dedicated CUA guard only for UI-specific assertions (frame hash preconditions, DOM/AX target matching, redaction enforcement). + +## Risks, bypass vectors, and mitigations + +### Bypass vector: agent escapes the tool boundary + +If the agent can access the real desktop directly (e.g., running code with OS privileges), it can bypass the gateway and produce unsound receipts. Mitigation: run agents outside the controlled desktop and only let them interact via the gateway; isolate the controlled runtime in containers/microVMs with restricted host interfaces (gVisor/Firecracker/Kata). citeturn8search1turn19search3turn19search0turn22search0 + +### Bypass vector: policy‑unsafe input injection privileges (especially on Linux) + +Granting broad `/dev/uinput` permissions allows any process with access to emulate input devices; this is powerful and dangerous.

[References](#references) + +--- + +## Overview + +A CUA gateway that targets browser-based workflows has access to the richest instrumentation surface available to any desktop automation platform. Browsers expose: + +1. **Structured DOM context** -- every element has a queryable tree position, attributes, and text content. +2. **Accessibility trees** -- semantic role, name, description, and state for every interactive element. +3. **Deterministic screenshot and tracing APIs** -- pixel-perfect evidence capture at arbitrary points. +4. **Network event streams** -- full request/response visibility for policy enforcement. +5. **Programmatic input dispatch** -- coordinate-level and element-level click, type, and scroll. + +The browser-first MVP path leverages all five of these surfaces through a combination of high-level automation frameworks (Playwright, Puppeteer, Selenium) and low-level protocols (CDP, WebDriver BiDi). The gateway sits between the agent and the browser, mediating every action through policy checks and capturing evidence for receipts. + +### Architecture Principle + +The agent never holds a direct reference to a browser page or CDP socket. All browser interactions flow through the gateway: + +``` +Agent (untrusted) + | + +-- computer.use JSON-RPC request + | + v +CUA Gateway (policy + evidence + signing) + | + +-- Policy check (egress, action type, target validation) + | + +-- Pre-action evidence capture (screenshot + AX snapshot) + | + +-- Action execution (Playwright / CDP / chromedp) + | + +-- Post-action evidence capture + | + +-- Receipt construction (hash chain + metadata) + | + v +Browser Instance (Chromium / Firefox / WebKit) + (controlled exclusively by gateway) +``` + +--- + +## Playwright + +### Playwright Architecture + +Playwright (Apache-2.0, Microsoft) is a browser automation framework with official bindings for TypeScript/JavaScript, Python, Java, and .NET. It controls browsers through a persistent WebSocket connection to browser-specific server processes. + +**Layered object model:** + +``` +Playwright Instance + | + +-- Browser (one per engine: Chromium, Firefox, WebKit) + | | + | +-- BrowserContext (isolated session, equivalent to incognito profile) + | | | + | | +-- Page (single tab/window) + | | | | + | | | +-- Frame (main frame + iframes) + | | | | | + | | | | +-- Locators (element references) + | | | | + | | | +-- Request / Response (network events) + | | | + | | +-- Page (another tab) + | | + | +-- BrowserContext (another isolated session) + | + +-- Browser (another engine) +``` + +**Key architectural properties:** + +| Component | Role | Isolation Level | +|-----------|------|-----------------| +| `Browser` | Controls a real browser process (Chromium, Firefox, or WebKit). One process per `Browser` instance. | Process-level | +| `BrowserContext` | Independent session with own cookies, localStorage, cache, permissions, viewport. Equivalent to an incognito profile. | Session-level | +| `Page` | A single tab within a context. Has its own DOM, JavaScript execution context, and network stack. | Tab-level | +| `Frame` | Main frame or iframe within a page. Each frame has its own document and execution context. | Document-level | + +**BrowserContext isolation** is the key property for CUA: each agent session gets its own context, preventing cookie/storage leakage between sessions. Contexts are cheap to create (no browser restart) and fast to tear down. + +**Browser server mode.** Playwright supports launching a browser server that exposes a WebSocket endpoint for remote connections: + +```typescript +import { chromium } from 'playwright'; + +// Launch a browser server (gateway side) +const server = await chromium.launchServer({ + headless: true, + port: 0, // auto-assign +}); +const wsEndpoint = server.wsEndpoint(); +// wsEndpoint example: ws://127.0.0.1:43567/abc123 + +// Connect from another process +const browser = await chromium.connect(wsEndpoint); +const context = await browser.newContext(); +const page = await context.newPage(); +``` + +This server mode is directly applicable to CUA: the gateway launches the browser server, holds the WebSocket endpoint privately, and never exposes it to the agent. + +### Playwright Cross-Engine + +Playwright supports three browser engines with a single API: + +| Engine | Upstream | Channel Option | CUA Notes | +|--------|----------|----------------|-----------| +| **Chromium** | Chrome for Testing (as of v1.57) | `channel: 'chrome'`, `channel: 'msedge'` | Primary target. Full CDP access. Best tooling. | +| **Firefox** | Custom Firefox build with Playwright patches | N/A (bundled) | Useful for cross-browser validation. No CDP; uses Playwright's internal protocol. | +| **WebKit** | WebKit trunk build | N/A (bundled) | Safari behavior testing. Limited to Playwright's own protocol. | + +**Cross-engine caveats for CUA:** + +- CDP-specific features (`Accessibility.getFullAXTree`, `Page.captureScreenshot` at protocol level) are only available on Chromium. +- Playwright's high-level APIs (`page.screenshot()`, `page.accessibility.snapshot()`) work across all engines, abstracting protocol differences. +- For the MVP, target Chromium exclusively and use Playwright's cross-engine support as a future extension path. + +### Playwright Tracing + +Playwright's Tracing API captures a comprehensive record of browser operations, network activity, and visual snapshots during test execution. + +**Starting and stopping traces:** + +```typescript +const context = await browser.newContext(); + +// Start tracing with screenshots and DOM snapshots +await context.tracing.start({ + screenshots: true, + snapshots: true, + sources: true, // include source code in trace +}); + +const page = await context.newPage(); +await page.goto('https://example.com'); +await page.click('button#submit'); + +// Stop and save trace +await context.tracing.stop({ + path: 'trace.zip', +}); +``` + +**Trace chunks** allow multiple traces within a single context: + +```typescript +await context.tracing.start({ screenshots: true, snapshots: true }); + +// First action sequence +await context.tracing.startChunk(); +await page.goto('https://example.com/step1'); +await context.tracing.stopChunk({ path: 'trace-step1.zip' }); + +// Second action sequence +await context.tracing.startChunk(); +await page.click('#next'); +await context.tracing.stopChunk({ path: 'trace-step2.zip' }); + +await context.tracing.stop(); +``` + +**Trace viewer** is a built-in GUI that loads trace files locally in the browser: + +```bash +npx playwright show-trace trace.zip +``` + +The trace viewer provides: +- Timeline of actions with screenshots at each step +- DOM snapshots (before and after each action) +- Network request log with timing +- Console output +- Source code context + +**HAR recording** captures network traffic in HTTP Archive format: + +```typescript +const context = await browser.newContext({ + recordHar: { + path: 'network.har', + mode: 'minimal', // or 'full' for response bodies + urlFilter: /api\/.*/, // optional URL filter + }, +}); + +// ... perform actions ... + +// HAR is saved when context closes +await context.close(); +``` + +**CUA relevance:** + +- Traces serve as rich evidence artifacts for receipts (screenshots + DOM snapshots + network log in a single archive). +- Trace chunks align naturally with per-action evidence capture: one chunk per `computer.use` action. +- HAR recordings enable network-level audit without separate tooling. +- Trace artifacts are self-contained zip files that can be hashed for tamper evidence. + +### Playwright Screenshots + +Playwright provides multiple screenshot capture methods: + +**Full-page screenshot:** + +```typescript +// Capture the entire scrollable page +await page.screenshot({ + path: 'full-page.png', + fullPage: true, +}); +``` + +**Viewport screenshot (default):** + +```typescript +// Capture only the visible viewport +await page.screenshot({ + path: 'viewport.png', +}); +``` + +**Clipped region:** + +```typescript +// Capture a specific rectangular region +await page.screenshot({ + path: 'region.png', + clip: { x: 100, y: 200, width: 600, height: 400 }, +}); +``` + +**Element screenshot:** + +```typescript +// Capture a specific element +await page.locator('button#submit').screenshot({ + path: 'submit-button.png', +}); +``` + +**Screenshot options reference:** + +| Option | Type | Default | Description | +|--------|------|---------|-------------| +| `path` | string | -- | File path to save the image | +| `type` | `'png'` / `'jpeg'` | `'png'` | Image format | +| `quality` | number (0-100) | -- | JPEG/WebP quality (not applicable to PNG) | +| `fullPage` | boolean | `false` | Capture full scrollable page | +| `clip` | `{x, y, width, height}` | -- | Specific region (mutually exclusive with `fullPage`) | +| `omitBackground` | boolean | `false` | Transparent background (PNG only) | +| `mask` | Locator[] | -- | Elements to mask with pink overlay boxes | +| `maskColor` | string | `'#FF00FF'` | Color for masked regions | +| `scale` | `'css'` / `'device'` | `'device'` | Pixel scale | + +**CUA evidence capture pattern:** + +```typescript +async function captureEvidence(page: Page): Promise<{ + screenshot: Buffer; + hash: string; +}> { + const screenshot = await page.screenshot({ type: 'png' }); + const hash = crypto.createHash('sha256').update(screenshot).digest('hex'); + return { screenshot, hash: `sha256:${hash}` }; +} +``` + +### Playwright Accessibility + +Playwright provides two complementary accessibility APIs: programmatic snapshots and ARIA snapshot matching. + +**Accessibility snapshot (`page.accessibility.snapshot()`):** + +```typescript +const snapshot = await page.accessibility.snapshot(); +// Returns a tree structure: +// { +// role: 'WebArea', +// name: 'Example Page', +// children: [ +// { role: 'heading', name: 'Welcome', level: 1 }, +// { role: 'button', name: 'Submit', focused: true }, +// { role: 'textbox', name: 'Email', value: 'user@example.com' }, +// ... +// ] +// } + +// Snapshot rooted at a specific element +const buttonSnapshot = await page.accessibility.snapshot({ + root: page.locator('form#login'), +}); +``` + +**Snapshot properties per node:** + +| Property | Type | Description | +|----------|------|-------------| +| `role` | string | ARIA role (`button`, `textbox`, `heading`, `link`, ...) | +| `name` | string | Accessible name (label text, aria-label, etc.) | +| `value` | string | Current value (text fields, sliders) | +| `description` | string | Accessible description | +| `checked` | boolean/`'mixed'` | Checkbox/radio state | +| `disabled` | boolean | Whether element is disabled | +| `expanded` | boolean | Expandable element state | +| `focused` | boolean | Whether element has keyboard focus | +| `level` | number | Heading level (1-6) | +| `pressed` | boolean/`'mixed'` | Toggle button state | +| `selected` | boolean | Selection state | +| `children` | AXNode[] | Child nodes in the accessibility tree | + +**ARIA snapshot matching (introduced in v1.49):** + +Playwright introduced ARIA snapshot testing that uses a YAML-based template language for asserting accessibility tree structure: + +```typescript +// Assert that a form has the expected accessible structure +await expect(page.locator('form#login')).toMatchAriaSnapshot(` + - textbox "Email" + - textbox "Password" + - button "Sign In" + - link "Forgot password?" +`); +``` + +**ARIA snapshot features:** + +- **Partial matching**: Omit attributes or children to match only what matters. +- **Regex support**: `- button /Submit|Send/` matches either name. +- **Hierarchical nesting**: Indentation represents parent-child relationships. +- **Auto-generation**: Playwright codegen can generate ARIA snapshot assertions automatically. + +**CUA receipt value.** The accessibility snapshot serves multiple purposes in the CUA pipeline: + +1. **Semantic target resolution**: Find elements by role+name instead of CSS selectors. +2. **Pre-action context**: Hash the AX tree before action for tamper-evident evidence. +3. **Post-condition verification**: After clicking "Submit", verify the AX tree contains "Success" or expected new state. +4. **Anti-clickjacking**: Compare the AX tree target at coordinates (x, y) against the agent's declared intent. + +```typescript +// CUA pattern: verify target before clicking +async function verifiedClick( + page: Page, + target: { role: string;

[References](#references) + +--- + +## Overview + +For a CUA gateway that needs to control "real desktops" (beyond browser-only), the gateway must provide: + +1. **A controlled display surface** where applications run (virtual or physical) +2. **A remote access protocol** that the gateway uses to view and interact with that surface +3. **Session recording** to produce evidence for receipts +4. **Input injection** that is mediated exclusively through the gateway + +The key architectural principle is: **the gateway is the only participant that speaks the remote desktop protocol**. The agent never directly accesses the display; it sends structured action requests to the gateway, which translates them into input events on the controlled desktop and captures evidence of the result. + +### Corrections and caveats + +- Portal-mediated Wayland control is user-consent and environment dependent; it is not a generic unattended injection API. +- RD protocol features (clipboard/file transfer/drive mapping) are frequent exfil paths and must default to deny. +- VNC simplicity is useful for prototyping, but production expectations should prefer RDP/WebRTC where latency and bandwidth matter. + +### Pass #2 reviewer notes (2026-02-18) + +- REVIEW-P2-CORRECTION: Latency and throughput values in this file are indicative planning ranges, not guarantees. Benchmark on your own runtime profile before setting SLOs. +- REVIEW-P2-GAP-FILL: For each protocol decision, add the exact enforcement hook in Clawdstrike terms (`policy event -> guard result -> audit event -> receipt metadata`). +- REVIEW-P2-CORRECTION: Treat non-primary references (blogs, vendor examples) as context only. Use project docs/specs as normative inputs for design decisions. + +### Pass #2 execution criteria + +- Desktop session denies clipboard/file-transfer by default and emits explicit policy events for every deny/allow. +- Every injected action yields pre/post evidence hashes and an auditable chain link in receipt metadata. +- Reconnect/session-recovery path preserves evidence continuity (no orphan actions). +- Latency SLOs are measured per deployment profile (not copied from generic tables). + +### Pass #4 reviewer notes (2026-02-18) + +- REVIEW-P4-CORRECTION: Any "recommended stack" language must include explicit threat-tier assumptions (dev, internal prod, internet-exposed multi-tenant). +- REVIEW-P4-GAP-FILL: Add protocol feature-policy matrix (clipboard, file transfer, audio, drive mapping, printing, session sharing) with explicit default action per mode (`observe`, `guardrail`, `fail_closed`). +- REVIEW-P4-CORRECTION: Transport security statements should name concrete auth and cert-validation requirements, not protocol-level defaults alone. + +### Pass #4 implementation TODO block + +- [x] Define `remote_desktop_policy_matrix.yaml` with per-protocol side-channel controls (`./remote_desktop_policy_matrix.yaml`). +- [x] Add end-to-end policy-event mapping for connect, input, clipboard, transfer, and disconnect paths (`./policy_event_mapping.md`, `./policy_event_mapping.yaml`). +- [ ] Build repeatable latency harness (same host class, same codec, same frame size, warm/cold cache runs). +- [x] Add evidence continuity tests for reconnect, packet loss, and gateway restart scenarios (`./remote_session_continuity_suite.yaml`, `../../../../fixtures/policy-events/session-continuity/v1/cases.json`). + +--- + +## Apache Guacamole + +### Guacamole Architecture + +Apache Guacamole (Apache-2.0 license) is a clientless remote desktop gateway that supports VNC, RDP, SSH, and Telnet. "Clientless" means users access remote desktops through a web browser with no plugins or client software required. + +**System architecture:** + +``` + ┌─────────────────────────────────────────────┐ + │ User's Web Browser │ + │ ┌─────────────────────────────────────┐ │ + │ │ Guacamole JavaScript Client │ │ + │ │ (guacamole-common-js) │ │ + │ │ - Canvas rendering │ │ + │ │ - Input capture (keyboard/mouse) │ │ + │ │ - WebSocket transport │ │ + │ └──────────────┬──────────────────────┘ │ + └─────────────────┼──────────────────────────┘ + │ WebSocket (Guacamole protocol) + │ + ┌─────────────────▼──────────────────────────┐ + │ Guacamole Web Application │ + │ (Java servlet in Tomcat) │ + │ - Authentication / authorization │ + │ - Connection management │ + │ - Session recording configuration │ + │ - REST API │ + └─────────────────┬──────────────────────────┘ + │ Guacamole protocol (TCP) + │ + ┌─────────────────▼──────────────────────────┐ + │ guacd (Native Proxy Daemon) │ + │ (C, uses libguac) │ + │ - Protocol translation (VNC, RDP, SSH) │ + │ - Client plugins (dynamically loaded) │ + │ - Session recording (protocol dumps) │ + │ - Audio/video encoding │ + └─────────────────┬──────────────────────────┘ + │ VNC / RDP / SSH + │ + ┌─────────────────▼──────────────────────────┐ + │ Remote Desktop Server │ + │ (VNC server, RDP server, SSH server) │ + └────────────────────────────────────────────┘ +``` + +**Key architectural properties:** + +- **Protocol agnosticism**: The web application and client only understand the Guacamole protocol. guacd handles all remote desktop protocol translation. Adding support for a new protocol only requires a new guacd plugin. +- **Separation of concerns**: Authentication, authorization, and connection management are in the Java web app; raw protocol handling is in the C daemon (guacd). +- **Stateless web tier**: The web application can be scaled horizontally; guacd handles the stateful protocol connections. +- **Extensible auth**: Supports database (MySQL/PostgreSQL), LDAP, TOTP, header-based, OpenID Connect, SAML, and custom auth extensions. + +### Guacamole Protocol + +The Guacamole protocol is a custom protocol designed for remote display rendering and event transport. It operates at a higher level than VNC/RDP, abstracting the actual remote desktop protocol away from the client. + +**Protocol characteristics:** +- Text-based, human-readable instruction format +- Instructions are comma-delimited with length-prefixed fields +- Supports drawing operations, audio, clipboard, file transfer +- Bidirectional: client sends input events, server sends display updates + +**Instruction categories:** + +| Category | Examples | Description | +|----------|----------|-------------| +| Drawing | `png`, `rect`, `copy`, `cfill` | Render graphics on the client canvas | +| Streaming | `img`, `blob`, `ack`, `end` | Transfer binary data (images, files) | +| Input | `mouse`, `key` | Keyboard and mouse events from client | +| Control | `sync`, `disconnect`, `nop` | Session lifecycle and synchronization | +| Audio | `audio` | Audio stream from remote session | +| Clipboard | `clipboard` | Clipboard content transfer | + +**CUA gateway relevance:** +- The protocol acts as a natural mediation point: the gateway can inspect, filter, and log every instruction +- Drawing instructions can be replayed for audit (protocol dumps are essentially recordings) +- Input events are explicit and inspectable (coordinates, key codes) +- Clipboard and file transfer can be policy-gated at the protocol level + +### Guacamole Session Recording + +Guacamole supports recording sessions at the protocol level, which is distinct from and more efficient than raw video capture. + +**Recording mechanism:** +- Sessions are recorded as **Guacamole protocol dumps** (raw instruction streams) +- Recording is configured per-connection in the Guacamole admin interface +- The recording file captures every drawing instruction, input event, and timing + +**Playback options:** + +1. **In-browser playback**: Guacamole can play back recordings directly in the browser using its JavaScript client. The recording is re-rendered in real time, producing a faithful reproduction of the session. + +2. **Video conversion (guacenc)**: The `guacenc` utility converts protocol dumps to standard video files. + +```bash +# Convert recording to MPEG-4 video +guacenc /path/to/recording + +# Output: /path/to/recording.m4v +# Default: 640x480, 2 Mbps bitrate + +# Custom resolution +guacenc -s 1920x1080 /path/to/recording + +# Custom resolution and bitrate +guacenc -s 1280x720 -r 4000000 /path/to/recording +``` + +**guacenc internals:** +- Processes Guacamole protocol instruction streams +- Renders frames using the same logic as the web client +- Encodes to MPEG-4 using FFmpeg libraries (libavcodec, libavformat, libswscale) +- Preserves timing from the original session + +**Advantages over raw video recording:** +- **Smaller file sizes**: Protocol dumps are much smaller than raw video +- **Lossless fidelity**: Re-rendering produces pixel-perfect output +- **Searchable**: Protocol instructions can be parsed for specific events +- **Flexible output**: Can generate video at any resolution/quality after the fact +- **Timestamped events**: Input events (clicks, keystrokes) have exact timestamps + +**CUA gateway relevance:** +- Protocol dumps serve as a natural receipt artifact +- Each input event in the dump corresponds to an agent action +- Dumps can be hashed for tamper-evident chains +- Video conversion provides human-reviewable audit artifacts +- In-browser playback enables real-time monitoring + +### Guacamole REST API + +Guacamole provides a REST API for programmatic management: + +**Authentication:** +```bash +# Obtain auth token +curl -X POST "https://guacamole.example.com/api/tokens" \ + -d "username=admin&password=secret" +# Returns: { "authToken": "...", "username": "admin", ... } +``` + +**Connection management:** +```bash +# List connections +curl -H "Guacamole-Token: $TOKEN" \ + "https://guacamole.example.com/api/session/data/postgresql/connections" + +# Create connection +curl -X POST -H "Content-Type: application/json" \ + -H "Guacamole-Token: $TOKEN" \ + "https://guacamole.example.com/api/session/data/postgresql/connections" \ + -d '{ + "parentIdentifier": "ROOT", + "name": "agent-desktop-1", + "protocol": "vnc", + "parameters": { + "hostname": "desktop-container-1", + "port": "5900", + "password": "...", + "recording-path": "/recordings", + "recording-name": "session-${GUAC_DATE}-${GUAC_TIME}" + } + }' +``` + +**Key API endpoints:** + +| Endpoint | Method | Description | +|----------|--------|-------------| +| `/api/tokens` | POST | Authenticate, get token | +| `/api/session/data/{source}/connections` | GET/POST | List/create connections | +| `/api/session/data/{source}/connections/{id}` | GET/PUT/DELETE | Manage connection | +| `/api/session/data/{source}/connections/{id}/parameters` | GET | Get connection parameters | +| `/api/session/data/{source}/activeConnections` | GET | List active sessions | +| `/api/session/data/{source}/history/connections` | GET | Connection history | +| `/api/session/data/{source}/users` | GET/POST | User management | + +**AUDIT permission (v1.6.0):** A new permission type for read-only access to session history, useful for monitoring and compliance without full admin access. + +### Guacamole Deployment + +**Docker deployment (typical 3-container setup):** + +```yaml +# docker-compose.yml +version: "3.9" +services: + guacd: + image: guacamole/guacd:1.6.0 + restart: unless-stopped + volumes: + -

[References](#references) + +--- + +## Overview + +A Computer-Use Agent (CUA) gateway must translate high-level agent intents (e.g., "click the Submit button") into low-level input events that the operating system and applications process as if they came from a physical human user. The choice of injection mechanism has deep implications for: + +- **Security**: Who can inject? What privilege boundaries exist? +- **Fidelity**: Are injected events indistinguishable from real hardware events? +- **Semantic richness**: Can we target UI elements by role/name rather than pixel coordinates? +- **Auditability**: Can we produce receipts that capture *what* was targeted, not just *where* we clicked? +- **Portability**: Does the mechanism work across display servers, desktop environments, and OS versions? + +This document surveys the full landscape of input injection and control surface APIs across Linux, Windows, and macOS, with particular attention to the Wayland transition on Linux and its implications for CUA gateway architecture. + +### Pass #2 reviewer notes (2026-02-18) + +- REVIEW-P2-CORRECTION: Prefer remote-desktop protocol mediation as the default execution path; direct host injection paths should be explicitly marked as higher-risk fallback modes. +- REVIEW-P2-GAP-FILL: Add a per-platform "verification contract" after each injection call (what state must change, and how to fail closed if it does not). +- REVIEW-P2-CORRECTION: Claims about compositor support and portal behavior should be validated against current release docs before production commitments. + +### Pass #2 execution criteria + +- Injection success is confirmed by post-condition checks (not API return values alone). +- Every platform backend reports standardized failure classes (permission, privilege boundary, target mismatch, timeout). +- High-risk host-level injection modes require explicit policy enablement and audit tagging. +- Wayland flow includes explicit portal/session lifecycle handling and deterministic denial behavior. + +### Pass #4 reviewer notes (2026-02-18) + +- REVIEW-P4-CORRECTION: Distinguish "API accepted event" from "target performed intended UI action" in all backend contracts. +- REVIEW-P4-GAP-FILL: Add threat-tier defaults for injection backends (protocol-mediated first, host-level injection opt-in only). +- REVIEW-P4-CORRECTION: Platform support claims (especially compositor/libei coverage) need release-pinned validation before production commitments. + +### Pass #4 implementation TODO block + +- [x] Define a unified injection outcome schema (`accepted`, `applied`, `verified`, `denied`, `unknown`) with reason codes (`./injection_outcome_schema.json`). +- [x] Add backend capability manifest per platform/runtime and load it at session start (`./injection_backend_capabilities.yaml`). +- [x] Add deterministic post-condition probes for click/type/scroll/key-chord actions (`./postcondition_probe_suite.yaml`, `../../../../fixtures/policy-events/postcondition-probes/v1/cases.json`). +- [x] Add negative tests for ambiguous targets, permission revocation mid-session, and focus-steal races (`../../../../fixtures/policy-events/postcondition-probes/v1/cases.json`). + +--- + +## Linux Input Injection + +### uinput Kernel Module + +**What it is.** `uinput` is a Linux kernel module that allows userspace programs to create virtual input devices. By writing to `/dev/uinput` (or `/dev/input/uinput`), a process creates a device that appears to the rest of the system exactly like a physical keyboard, mouse, touchscreen, or other HID device. Events written to this virtual device are delivered to all consumers (both userspace applications and in-kernel handlers) through the standard evdev subsystem. + +**Device creation flow.** + +```c +#include +#include +#include +#include + +int fd = open("/dev/uinput", O_WRONLY | O_NONBLOCK); + +// 1.

Create the device +ioctl(fd, UI_DEV_CREATE); + +// Device is now live in /dev/input/eventN +``` + +**Writing events.** Once the device is created, events are injected by writing `struct input_event` records: + +```c +struct input_event ev; + +// Key press: 'A' +ev.type = EV_KEY; +ev.code = KEY_A; +ev.value = 1; // 1 = press, 0 = release, 2 = repeat +write(fd, &ev, sizeof(ev)); + +// Synchronize (marks end of an atomic event group) +ev.type = EV_SYN; +ev.code = SYN_REPORT; +ev.value = 0; +write(fd, &ev, sizeof(ev)); + +// Key release: 'A' +ev.type = EV_KEY; +ev.code = KEY_A; +ev.value = 0; +write(fd, &ev, sizeof(ev)); + +ev.type = EV_SYN; +ev.code = SYN_REPORT; +ev.value = 0; +write(fd, &ev, sizeof(ev)); +``` + +**Permission model.** Access to `/dev/uinput` is controlled by standard Unix file permissions. Typically: + +- The device node is owned by `root:root` with mode `0660` or `0600`. +- A udev rule can grant access to a specific group (e.g., `input` or a custom `uinput` group): + ``` + # /etc/udev/rules.d/99-uinput.rules + KERNEL=="uinput", GROUP="uinput", MODE="0660" + ``` +- In containerized environments, the device must be explicitly bind-mounted and appropriate capabilities (or device cgroup rules) granted: + ```bash + docker run --device /dev/uinput:/dev/uinput ... + ``` + +**Security considerations for CUA.** + +| Concern | Detail | +|---------|--------| +| Broad injection scope | Any process with `/dev/uinput` access can inject events system-wide, affecting all applications and display servers | +| No per-application targeting | uinput operates at the kernel level; events go to whoever has focus or is listening on the evdev node | +| Container isolation required | In a CUA gateway, the uinput device should only be accessible inside an isolated runtime (container/VM), never on a shared host | +| Audit trail | uinput itself produces no audit log; the gateway must capture pre/post evidence independently | +| Silent injection failures | If the virtual device is not set up with the correct capabilities, events may be silently dropped | + +**Best practice for CUA gateway.** Use uinput only inside a dedicated, isolated desktop runtime (e.g., a container running Xvfb or a headless Wayland compositor). The gateway process should be the sole entity with `/dev/uinput` access, and the runtime should have no network egress except through the gateway's policy layer. Log device-level injection grants (e.g., `/dev/uinput`) as high-severity audit metadata. + +--- + +### libevdev uinput Helpers + +**What it is.** `libevdev` is a C library that wraps the Linux evdev and uinput kernel interfaces, providing a safer and more ergonomic API for virtual device creation and event injection. It is maintained by the freedesktop.org project and is the recommended way to interact with uinput in production code. + +**Key API functions.** + +| Function | Purpose | +|----------|---------| +| `libevdev_uinput_create_from_device()` | Create a uinput device that mirrors the capabilities of an existing `libevdev` device. Optionally manages the `/dev/uinput` fd internally when passed `LIBEVDEV_UINPUT_OPEN_MANAGED` | +| `libevdev_uinput_write_event()` | Write a single event (type, code, value) to the virtual device; handles `SYN_REPORT` framing | +| `libevdev_uinput_get_devnode()` | Returns the `/dev/input/eventN` path for the created virtual device | +| `libevdev_uinput_get_syspath()` | Returns the sysfs path for device introspection | +| `libevdev_uinput_destroy()` | Destroys the virtual device and frees resources | + +**Device cloning pattern.** One of libevdev's most useful features for CUA is the ability to clone an existing device's capabilities: + +```c +#include +#include + +// Create a libevdev device with desired capabilities +struct libevdev *dev = libevdev_new(); +libevdev_set_name(dev, "CUA Gateway Keyboard"); +libevdev_enable_event_type(dev, EV_KEY); + +// Enable all standard keyboard keys +for (int k = KEY_ESC; k <= KEY_MICMUTE; k++) { + libevdev_enable_event_code(dev, EV_KEY, k, NULL); +} + +// Create the uinput device (managed fd) +struct libevdev_uinput *uidev; +int err = libevdev_uinput_create_from_device( + dev, + LIBEVDEV_UINPUT_OPEN_MANAGED, + &uidev +); + +if (err == 0) { + // Inject a key press + libevdev_uinput_write_event(uidev, EV_KEY, KEY_ENTER, 1); + libevdev_uinput_write_event(uidev, EV_SYN, SYN_REPORT, 0); + + // Release + libevdev_uinput_write_event(uidev, EV_KEY, KEY_ENTER, 0); + libevdev_uinput_write_event(uidev, EV_SYN, SYN_REPORT, 0); +} + +// Cleanup +libevdev_uinput_destroy(uidev); +libevdev_free(dev); +``` + +**Python bindings.** The `python-libevdev` package provides Pythonic access: + +```python +import libevdev + +dev = libevdev.Device() +dev.name = "CUA Gateway Mouse" +dev.enable(libevdev.EV_REL.REL_X) +dev.enable(libevdev.EV_REL.REL_Y) +dev.enable(libevdev.EV_KEY.BTN_LEFT) +dev.enable(libevdev.EV_KEY.BTN_RIGHT) + +uinput = dev.create_uinput_device() + +# Move mouse and click +uinput.send_events([ + libevdev.InputEvent(libevdev.EV_REL.REL_X, 100), + libevdev.InputEvent(libevdev.EV_REL.REL_Y, 50), + libevdev.InputEvent(libevdev.EV_SYN.SYN_REPORT, 0), +]) + +uinput.send_events([ + libevdev.InputEvent(libevdev.EV_KEY.BTN_LEFT, 1), + libevdev.InputEvent(libevdev.EV_SYN.SYN_REPORT, 0), +]) + +uinput.send_events([ + libevdev.InputEvent(libevdev.EV_KEY.BTN_LEFT, 0), + libevdev.InputEvent(libevdev.EV_SYN.SYN_REPORT, 0), +]) +``` + +**Advantages over raw uinput.** + +- Handles capability negotiation correctly (uinput silently drops unsupported capabilities; libevdev documents this behavior). +- Manages the `/dev/uinput` file descriptor lifecycle. +- Provides a consistent API across kernel versions. +- Error reporting is clearer than raw ioctl return codes. +- The device's lifetime is tied to the uinput file descriptor, and closing it will destroy the uinput device. Calling `libevdev_uinput_destroy()` before closing frees allocated resources. + +--- + +### XTEST / XTestFakeInput (X11) + +**What it is.** XTEST is an X11 extension (specified as part of X11R6.4+) that allows X clients to inject synthetic keyboard and mouse events directly into the X server's event processing pipeline. The events are treated as if they originated from physical hardware, making them indistinguishable to applications. + +**Core API.** + +```c +#include + +Display *dpy = XOpenDisplay(NULL); + +// Check for XTEST extension support +int event_base, error_base, major, minor; +Bool supported = XTestQueryExtension(dpy, &event_base, &error_base, + &major, &minor); + +// Inject a key press (keycode for 'a') +XTestFakeKeyEvent(dpy, XKeysymToKeycode(dpy, XK_a), True, CurrentTime); +XFlush(dpy); + +// Inject a key release +XTestFakeKeyEvent(dpy, XKeysymToKeycode(dpy, XK_a), False, CurrentTime); +XFlush(dpy); + +// Inject a mouse button press at current pointer position +XTestFakeButtonEvent(dpy, 1, True, CurrentTime); // Button 1 = left +XFlush(dpy); + +// Inject a mouse button release +XTestFakeButtonEvent(dpy, 1, False, CurrentTime); +XFlush(dpy); + +// Move pointer to absolute position +XTestFakeMotionEvent(dpy, -1, 500, 300, CurrentTime); +XFlush(dpy); +``` + +**Convenience wrappers.** + +| Function | Description | +|----------|-------------| +| `XTestFakeKeyEvent(dpy, keycode, is_press, delay)` | Inject a key press or release event | +| `XTestFakeButtonEvent(dpy, button, is_press, delay)` | Inject a mouse button press or release | +| `XTestFakeMotionEvent(dpy, screen, x, y, delay)` | Move pointer to absolute coordinates | +| `XTestFakeRelativeMotionEvent(dpy, dx, dy, delay)` | Move pointer by relative offset | +| `XTestGrabControl(dpy, impervious)` | Control whether active grabs affect fake events | + +**Important behavior notes.** + +- Each `XTestFakeInput()` call is a single user action: a button press and button release must be two separate calls. +- The extension is not intended to support general journaling and playback of user actions; it is designed for testing purposes. +- The `delay` parameter specifies milliseconds to wait before the event is processed (0 or `CurrentTime` = immediate). + +**Security implications.** + +The X11 trust model is fundamentally permissive: **any client connected to the X server can use XTEST to inject events into any other client's windows.** There is no per-client or per-application authorization. + +| Risk | Detail | +|------|--------| +| No isolation between X clients | Any X application can observe keystrokes (keylogger), inject events, and read screen contents of other applications | +| No permission prompt | Unlike Wayland portals or macOS accessibility permissions, X11 grants XTEST access silently | +| Network X forwarding amplifies risk | If the X display is network-accessible, remote injection is trivial | +| Acceptable only in isolated containers | For CUA, XTEST is safe only when the X server runs inside an isolated container/VM with no other sensitive applications | + +**Practical relevance for CUA.** XTEST remains the simplest and most reliable injection mechanism for Linux CUA runtimes that use X11 (especially Xvfb-based headless desktops). The security concerns are mitigated by running Xvfb inside a container where the CUA gateway is the only X client besides the target application. + +**xdotool.** The widely-used `xdotool` command-line tool wraps XTEST for scripted automation: + +```bash +# Type text +xdotool type "Hello, world" + +# Click at coordinates +xdotool mousemove 500 300 click 1 + +# Press a key combination +xdotool key ctrl+s + +# Focus a window by name and click +xdotool search --name "Firefox" windowactivate +xdotool mousemove --window $(xdotool search --name "Firefox") 100 200 click 1 +``` + +--- + +### libei (Wayland Input Emulation) + +**What it is.** `libei` (Emulated Input) is a library developed by Red Hat's Peter Hutterer that provides a standardized way for applications to send emulated input events to Wayland compositors. It was created to solve the problem that Wayland's security model intentionally prevents the X11-style "any client can inject input" pattern. libei 1.0 was released with stable API/ABI guarantees. + +**Architecture.** libei has a client-server design: + +- **libei** (client side): Used by applications that want to inject input (e.g., a CUA gateway, Synergy/Barrier, virtual keyboards). +- **libeis** (server side): Integrated into the Wayland compositor to receive and validate emulated input events. The compositor can distinguish libei events from real hardware events, enabling fine-grained access control. + +**How it works with portals.** The XDG Desktop Portal `RemoteDesktop` interface provides the bridge: + +1. Application requests a RemoteDesktop session through the portal D-Bus API. +2. The portal prompts the user for consent (auto-grant behavior is deployment-specific policy, not a universal default). +3. Application calls `org.freedesktop.portal.RemoteDesktop.ConnectToEIS` to get a connection to the compositor's EIS (Emulated Input Server). +4. Application uses libei to create virtual devices and send events over the EIS connection. + +``` +Application (libei client) + | + +-- D-Bus --> XDG Portal (RemoteDesktop) + | | + | v + | User consent prompt + | | + | ConnectToEIS() + | | + v v +libei <------------> libeis (in compositor) + | + v + Input processing pipeline +``` + +**Current compositor adoption (2025-2026).** + +| Compositor | libei/libeis support | +|------------|---------------------| +| Mutter (GNOME) | Supported since GNOME 45 | +| KWin (KDE) | Under active development | +| wlroots (Sway, etc.) | Tracked in wlroots issue #2378; community patches available | +| Hyprland | Portal-based via xdg-desktop-portal-hyprland | + +**Real-world adoption example.** RustDesk (open-source remote desktop) has implemented unprivileged remote access on Wayland through the RemoteDesktop portal and libei, demonstrating the viability of this path for CUA-like systems. Input-Leap (Synergy/Barrier successor) also has a libei backend PR. + +**Significance for CUA.** libei is the "correct" way to do input injection on modern Wayland desktops. For CUA gateways targeting Wayland, the recommended path is: + +1. Use the RemoteDesktop portal to establish a session (handles permissions). +2. Use libei to inject keyboard and mouse events. +3. Combine with the ScreenCast portal for frame capture. + +This is more complex than XTEST but provides proper security mediation and is the only path that is both compositor-portable and sanctioned by the Wayland ecosystem. + +--- + +## Windows Input Injection + +### Win32 SendInput + +**What it is.** `SendInput` is the canonical Win32 API for synthesizing keyboard and mouse input events. It inserts events into the global input stream, where they are processed by the system as if they came from physical hardware. + +**API signature.** + +```c +UINT SendInput( + UINT cInputs, // Number of INPUT structures + LPINPUT pInputs, // Array of INPUT structures + int cbSize // Size of INPUT structure +); +``` + +**INPUT structure.** + +```c +typedef struct tagINPUT { + DWORD type; // INPUT_MOUSE, INPUT_KEYBOARD, or INPUT_HARDWARE + union { + MOUSEINPUT mi; + KEYBDINPUT ki; + HARDWAREINPUT hi; + } DUMMYUNIONNAME; +} INPUT; + +typedef struct tagMOUSEINPUT { + LONG dx; // X coordinate or delta + LONG dy; // Y coordinate or delta + DWORD mouseData; // Wheel delta or X button data + DWORD dwFlags; // MOUSEEVENTF_* flags + DWORD time; // Timestamp (0 = system provides) + ULONG_PTR dwExtraInfo; // Extra info (app-defined) +} MOUSEINPUT; + +typedef struct tagKEYBDINPUT { + WORD wVk; // Virtual-key code + WORD wScan; // Hardware scan code + DWORD dwFlags; // KEYEVENTF_* flags + DWORD time; // Timestamp + ULONG_PTR dwExtraInfo; // Extra info +} KEYBDINPUT; +``` + +**Usage example: typing a letter.** + +```c +// Type the letter 'A' +INPUT inputs[2] = {}; + +// Key down +inputs[0].type = INPUT_KEYBOARD; +inputs[0].ki.wVk = 'A'; +inputs[0].ki.dwFlags = 0; + +// Key up +inputs[1].type = INPUT_KEYBOARD; +inputs[1].ki.wVk = 'A'; +inputs[1].ki.dwFlags = KEYEVENTF_KEYUP; + +SendInput(2, inputs, sizeof(INPUT)); +``` + +**Usage example: mouse click at absolute position.** + +```c +INPUT inputs[2] = {}; + +// Move to absolute position (normalized 0-65535) +inputs[0].type = INPUT_MOUSE; +inputs[0].mi.dx = (int)(x * 65535.0 / screen_width); +inputs[0].mi.dy = (int)(y * 65535.0 / screen_height); +inputs[0].mi.dwFlags = MOUSEEVENTF_ABSOLUTE | MOUSEEVENTF_MOVE; + +// Left button down + up +inputs[1].type = INPUT_MOUSE; +inputs[1].mi.dwFlags = MOUSEEVENTF_LEFTDOWN | MOUSEEVENTF_LEFTUP; + +SendInput(2, inputs, sizeof(INPUT)); +``` + +**Key behaviors.** + +- Events are inserted serially into the input stream. +- `SendInput` is atomic: the sequence of events in a single call is guaranteed not to be interleaved with other hardware or software input. +- The function returns the number of events successfully inserted; check against `cInputs` for errors. +- `GetLastError()` is not a reliable UIPI diagnostic by itself; blocked injections can be silent. +- Blocked injections may have ambiguous signaling; require post-action state validation instead of trusting return values alone. + +--- + +### UIPI and Integrity Levels + +**User Interface Privilege Isolation (UIPI)** is a security mechanism introduced in Windows Vista that restricts which processes can send window messages and inject input into which other processes, based on their mandatory integrity level. + +**Integrity level hierarchy.** + +| Level | Label | Typical processes | +|-------|-------|-------------------| +| 0x0000 | Untrusted | Rarely used | +| 0x1000 | Low | Protected Mode IE, sandboxed apps | +| 0x2000 | Medium | Standard user applications | +| 0x3000 | High | Elevated (Run as Administrator) | +| 0x4000 | System | Windows services, kernel objects | + +**UIPI rules.** + +1. A process can only send window messages (including `SendInput` events) to processes at **equal or lower** integrity levels. +2. A lower-integrity process **cannot** inject input into a higher-integrity process. +3. This prevents a compromised medium-integrity browser from injecting keystrokes into an elevated command prompt. +4. UIPI also blocks `SetWindowsHookEx` across integrity boundaries. + +**UIAccess bypass.** Applications can be granted `UIAccess` permission to bypass UIPI restrictions. Requirements: + +- The application's manifest must declare ``. +- The binary must be digitally signed with a trusted certificate. +- The binary must be installed in a secure location (e.g., `%ProgramFiles%`, `%WinDir%`). +- The Group Policy setting "Only elevate UIAccess applications that are installed in secure locations" must be satisfied. + +**Implications for CUA gateway.** + +| Scenario | UIPI impact | +|----------|-------------| +| Gateway and target app both at medium IL | SendInput works normally | +| Target app is elevated (high IL) | SendInput from medium-IL gateway is expected to be blocked; error signaling can be ambiguous | +| Gateway inside a VM | UIPI is irrelevant; the gateway controls the entire desktop inside the VM | +| RDP-mediated injection | RDP input bypasses UIPI because it enters through the session's input stack at the system level | + +**Best practice.** For CUA, run the target desktop inside a Windows VM. The gateway injects input via RDP protocol or a dedicated agent inside the VM, avoiding UIPI complications entirely. If running on a shared desktop is required, request UIAccess, sign the binary, and install to a secure path. + +**Detection of UIPI failures.** Add explicit policy fields for input privilege level (`semantic_only`, `coordinate_allowed`, `raw_device_emulation`) and require the gateway to verify successful injection by checking post-action state changes rather than relying solely on `SendInput` return values. + +--- + +## macOS Input Injection + +### Quartz Event Services + +**What it is.** Quartz Event Services is the macOS (Core Graphics) framework for creating, posting, and intercepting low-level input events. It provides the ability to create synthetic keyboard and mouse events and inject them into the system's event stream. + +**Creating and posting keyboard events.** + +```swift +import CoreGraphics + +// Create a keyboard event (key down for 'a', virtual keycode 0) +let keyDown = CGEvent(keyboardEventSource: nil, virtualKey: 0, keyDown: true) +keyDown?.post(tap: .cghidEventTap) + +// Key up +let keyUp = CGEvent(keyboardEventSource: nil, virtualKey: 0, keyDown: false) +keyUp?.post(tap: .cghidEventTap) +``` + +**Creating and posting mouse events.** + +```swift +// Mouse click at (500, 300) +let mouseDown = CGEvent( + mouseEventSource: nil, + mouseType: .leftMouseDown, + mouseCursorPosition: CGPoint(x: 500, y: 300), + mouseButton: .left +) +mouseDown?.post(tap: .cghidEventTap) + +let mouseUp = CGEvent( + mouseEventSource: nil, + mouseType: .leftMouseUp, + mouseCursorPosition: CGPoint(x: 500, y: 300), + mouseButton: .left +) +mouseUp?.post(tap: .cghidEventTap) +``` + +**C API equivalents.** + +```c +#include + +// Keyboard event +CGEventRef keyEvent = CGEventCreateKeyboardEvent(NULL, (CGKeyCode)0, true); +CGEventPost(kCGHIDEventTap, keyEvent); +CFRelease(keyEvent); + +// Mouse event +CGEventRef mouseEvent = CGEventCreateMouseEvent( + NULL, + kCGEventLeftMouseDown, + CGPointMake(500, 300), + kCGMouseButtonLeft +); +CGEventPost(kCGHIDEventTap, mouseEvent); +CFRelease(mouseEvent); +``` + +**Event posting locations (tap locations).** + +| Tap location | Description | +|-------------|-------------| +| `kCGHIDEventTap` | Events injected at the HID level, before the window server processes them. Most common for input injection. | +| `kCGSessionEventTap` | Events injected at the session level, after HID processing but before application delivery. | +| `kCGAnnotatedSessionEventTap` | Events include annotations from the window server. | + +--- + +### Event Taps + +**What they are.** Event taps allow an application to observe and optionally modify the stream of low-level input events flowing through the system. They can be installed at various points in the event pipeline. While primarily useful for monitoring rather than injection, they are important for CUA evidence capture (observing what happened after injection). + +**Creating an event tap.** + +```swift +import CoreGraphics + +// Define the events to observe +let eventMask: CGEventMask = (1 << CGEventType.leftMouseDown.rawValue) | + (1 << CGEventType.keyDown.rawValue) + +// Create the tap +let tap = CGEvent.tapCreate( + tap: .cgSessionEventTap, + place: .headInsertEventTap, + options: .defaultTap, // .defaultTap can modify, .listenOnly cannot + eventsOfInterest: eventMask, + callback: { proxy, type, event, refcon in + // Inspect or modify the event + print("Event type: \(type)") + return Unmanaged.passRetained(event) + }, + userInfo: nil +) + +// Add to run loop +if let tap = tap { + let runLoopSource = CFMachPortCreateRunLoopSource(nil, tap, 0) + CFRunLoopAddSource(CFRunLoopGetCurrent(), runLoopSource, .commonModes) + CGEvent.tapEnable(tap: tap, enable: true) + CFRunLoopRun() +} +``` + +**Event tap options.** + +| Option | Behavior | +|--------|----------| +| `.defaultTap` | Can observe and modify events (active filter) | +| `.listenOnly` | Can observe but not modify events (passive listener) | + +--- + +### Permission Requirements + +**Accessibility permission.** On modern macOS (10.9+), applications that want to create event taps or post synthetic events via Quartz Event Services must be granted Accessibility permission by the user. + +**How permissions work.** + +1. The application calls `AXIsProcessTrusted()` to check if it has Accessibility permission. +2. If not trusted, `AXIsProcessTrustedWithOptions()` can prompt the user to open System Settings. +3. The user must manually add the application in **System Settings > Privacy & Security > Accessibility**. +4. The permission is stored per-application (by bundle identifier or path). +5. Changes require authentication with an administrator password. + +**Recent changes (macOS Sequoia / macOS 15).** + +- Apple has tightened restrictions on event taps. Some developers report that `CGEventTapCreate` returns `NULL` even when Accessibility permission is granted, with `AXIsProcessTrusted()` returning `true` but an undocumented `CanFilterEvents` check returning `false`. +- Background helper processes and launch daemons face additional restrictions. +- Sandboxed applications (App Store distribution) **cannot** request Accessibility permission at all. +- Event taps that modify events are more restricted than listen-only taps. + +**Implications for CUA.** + +| Scenario | Feasibility | +|----------|-------------| +| Unsandboxed app with Accessibility permission | Works, but requires manual user consent per application | +| Sandboxed App Store app | Not possible; cannot request Accessibility | +| CUA inside macOS VM (Apple Virtualization) | The gateway controls the VM; Accessibility can be pre-configured | +| CUA via VNC/ARD to macOS | Input enters via remote desktop protocol; no Accessibility permission needed for the remote client | + +**Best practice.** For production CUA on macOS, prefer VM isolation (Apple Virtualization Framework) or remote desktop mediation (VNC/ARD). Direct Quartz Event injection on a shared desktop requires Accessibility permission and is fragile across macOS updates. + +--- + +## Accessibility / Semantic Control Surfaces + +Accessibility APIs provide **semantic targeting**: instead of clicking at pixel coordinates (x=500, y=300), a CUA gateway can target "the button named 'Submit' in the dialog titled 'Confirm Purchase'." This dramatically improves: + +- **Receipt quality**: Receipts can record *what* was targeted, not just *where*. +- **Robustness**: Semantic targets survive UI layout changes, DPI scaling, and window repositioning. +- **Anti-clickjacking**: Coordinate-only clicks are vulnerable to UI spoofing; semantic matches are harder to spoof. +- **Post-action assertions**: The gateway can verify that the action had the intended effect by re-querying the accessibility tree. + +### Windows UI Automation (UIA) + +**What it is.** Microsoft UI Automation is a COM-based accessibility framework that exposes UI elements as a tree of automation elements, each with properties, control patterns, and events. It is the successor to MSAA (Microsoft Active Accessibility) and is the standard accessibility API for Windows applications. + +**Tree structure.** + +``` +Desktop (root) ++-- Window: "File Explorer" +| +-- ToolBar: "Navigation" +| | +-- Button: "Back" +| | +-- Button: "Forward" +| | +-- Button: "Up" +| +-- TreeView: "Folder Tree" +| | +-- TreeItem: "Desktop" +| | +-- TreeItem: "Documents" +| +-- ListView: "File List" +| +-- ListItem: "report.docx" +| +-- ListItem: "photo.jpg" ++-- Window: "Chrome" + +-- Document: "Google Search" + +-- Edit: "Search box" + +-- Button: "Google Search" +``` + +**Core interfaces (COM).** + +| Interface | Purpose | +|-----------|---------| +| `IUIAutomation` | Root COM object; creates conditions, tree walkers, retrieves elements.

no OS injection needed | + +--- + +## Implications for CUA Gateway Design + +### Architecture Recommendations + +1. **Prefer remote desktop protocol mediation over direct OS injection.** When the CUA gateway communicates with the target desktop via RDP, VNC, or WebRTC, input injection happens through the remote desktop protocol's input channel. This: + - Avoids platform-specific injection API complexity. + - Avoids permission issues (UIPI, macOS Accessibility). + - Works consistently across platforms. + - Is naturally isolated (the gateway never runs on the target desktop). + +2. **Layer semantic targeting on top of coordinate injection.** The gateway should: + - Query the accessibility tree (UIA, AXUIElement, AT-SPI) to resolve semantic targets to coordinates. + - Inject input at the resolved coordinates (via the chosen injection mechanism). + - Include both the semantic target and the coordinates in the receipt. + - Verify post-action accessibility state matches expectations. + - Require post-action assertions for privileged actions (URL/window title/text checks) to prevent blind injection drift. + +3. **For the MVP, start with Xvfb + XTEST + AT-SPI on Linux.** This combination: + - Is the simplest to set up (one container, no compositor complexity). + - Provides reliable injection (XTEST is battle-tested). + - Supports semantic targeting (AT-SPI for GTK/Qt/Electron apps). + - Runs headlessly without GPU. + - Can be captured via x11grab (FFmpeg) or VNC streaming. + +4. **Plan for Wayland transition.** As GNOME and KDE move to Wayland-only, the gateway must support: + - RemoteDesktop portal + libei for input. + - ScreenCast portal + PipeWire for capture. + - OR: Use a headless Wayland compositor (Weston RDP backend) where the gateway connects via RDP, sidestepping the portal flow entirely. + +5. **Never expose uinput or XTEST on shared desktops.** These mechanisms provide no isolation. A compromised CUA agent with uinput access can inject arbitrary input into any application on the system. Always confine these mechanisms inside isolated runtimes (containers, VMs). + +6. **Add explicit policy fields for input privilege level.** The policy engine should support: + - `semantic_only` -- only allow actions targeted by accessibility role/name. + - `coordinate_allowed` -- allow coordinate-based injection (with semantic validation if available). + - `raw_device_emulation` -- allow uinput/low-level injection (highest privilege, requires strongest isolation). + +### Receipt Evidence from Input Injection + +For each injected action, the receipt should capture: + +| Field | Source | Purpose | +|-------|--------|---------| +| `action.kind` | Gateway | What type of action (click, type, key_chord) | +| `action.pointer.{x,y}` | Gateway | Pixel coordinates of injection | +| `action.target_hint.role` | Accessibility API | Semantic role of target element | +| `action.target_hint.name` | Accessibility API | Name/label of target element | +| `action.target_hint.bounds` | Accessibility API | Bounding rectangle for cross-reference | +| `action.target_hint.window_title` | Accessibility API | Window containing the target | +| `action.target_hint.app_id` | Accessibility API | Application identity | +| `evidence.pre.frame_hash` | Screen capture | Hash of screen before action | +| `evidence.post.frame_hash` | Screen capture | Hash of screen after action | +| `evidence.ui_context.ax_tree_hash` | Accessibility API | Hash of accessibility tree snapshot | +| `injection.method` | Gateway | Which injection mechanism was used | +| `injection.privilege_level` | Policy engine | What level of injection was authorized | + +### Abuse Prevention + +- **Rate limits**: Cap click/keystroke rate to prevent runaway automation loops. +- **Input flood detection**: Monitor for anomalous injection frequency and auto-pause. +- **UIPI mismatch handling**: Detect and report when UIPI blocks injection; return deterministic failure reason. +- **Silent failure detection**: Verify post-action state changes rather than relying on injection API return values. + +--- + +## References + +### Linux uinput / libevdev +- [Linux Kernel uinput documentation](https://docs.kernel.org/input/uinput.html) +- [libevdev uinput device creation API](https://www.freedesktop.org/software/libevdev/doc/latest/group__uinput.html) +- [python-libevdev documentation](https://python-libevdev.readthedocs.io/) +- [libevdev source (GitHub)](https://github.com/whot/libevdev) + +### XTEST +- [XTEST Extension Protocol specification](https://www.x.org/releases/X11R7.7/doc/xextproto/xtest.html) +- [XTestFakeKeyEvent man page](https://linux.die.net/man/3/xtestfakekeyevent) + +### libei +- [libei 1.0 release (Phoronix)](https://www.phoronix.com/news/libei-1.0-Emulated-Input) +- [EI Protocol documentation](https://libinput.pages.freedesktop.org/libei/) +- [RFC: libei -

Evidence artifacts go through the redaction pipeline and are referenced by receipts. + +2. **Use lossless PNG for per-action evidence frames.** These are the frames that get SHA-256 hashed and referenced in receipts. Lossy compression would make hashes unreproducible. + +3. **Use lossy video for continuous session recording.** H.264 or H.265 for human-reviewable session replay. This is complementary to per-action evidence, not a replacement. + +4. **Include both SHA-256 and perceptual hashes.** SHA-256 provides exact integrity. Perceptual hashes enable similarity search and approximate change detection without retrieving full frames. + +5. **Leverage compositor-provided change metadata.** On Windows (dirty rects) and Wayland (video damage), the compositor knows exactly what changed. Use this instead of computing pixel diffs when available. + +6. **Include capture tool metadata in receipts.** The FFmpeg version, build configuration, and encoder settings affect how frames are produced. Include these digests in the artifact manifest for reproducibility during incident review. + +7. **Design the redaction pipeline as ordered stages.** Detect, mask, hash, sign -- in that order. The hash in the receipt references the post-redaction frame, and the redaction metadata documents what was removed and why. + +8. **Plan for storage cost.** At 10 fps, a 1920x1080 session generates: + -

Overview and Motivation + +A CUA gateway produces **receipts** -- signed attestations that a particular +agent action was evaluated against policy, that pixel/DOM evidence was captured, +and that the gateway itself was running a known, trusted build. The signing and +attestation stack determines: + +- **Who can forge receipts?** (key protection) +- **Can the host tamper with receipts after the fact?** (append-only logs, TEE isolation) +- **Can a third party verify receipts without trusting the gateway operator?** (transparency, remote attestation) + +The threat model from the source report identifies three adversaries: +**malicious agents**, **compromised hosts**, and **insider threats**. Each +requires progressively stronger signing and attestation guarantees. + +### Design Principles + +1. **Fail-closed**: Unknown signing backends reject operations; unsigned receipts are invalid. +2. **Pluggable signers**: The `Signer` trait (already in Clawdstrike) abstracts over in-memory keys, TPM-sealed seeds, and future TEE-backed keys. +3. **Layered trust**: MVP uses software keys; production adds hardware anchors; high-assurance adds TEE attestation and transparency logs. + +### Pass #2 reviewer notes (2026-02-18) + +- REVIEW-P2-CORRECTION: Throughput and latency values in this document are planning estimates unless tied to reproducible benchmark conditions. +- REVIEW-P2-GAP-FILL: Add verifier policy requirements explicitly (nonce freshness window, accepted attestation issuers, required claim set, clock-skew tolerance). +- REVIEW-P2-CORRECTION: Keep MVP compatibility with current Clawdstrike `SignedReceipt` verification as a hard requirement during signer/attestation upgrades. + +### Pass #2 execution criteria + +- Verifier rejects receipts missing required signature, schema-version, and provenance checks. +- Attestation-backed signing paths bind nonce and runtime claims to the signed receipt identity. +- Key rotation and revocation behavior is testable with deterministic pass/fail outcomes. +- Hardware-backed and software-backed signers produce equivalent canonical-verification results. + +### Pass #4 reviewer notes (2026-02-18) + +- REVIEW-P4-CORRECTION: Attestation trust is verifier-policy-dependent; document accepted issuers, claim requirements, and freshness windows as code/config, not prose. +- REVIEW-P4-GAP-FILL: Add migration sequencing from current signer path to hardware/TEE-backed paths with explicit rollback strategy. +- REVIEW-P4-CORRECTION: "High assurance" claims must require both key protection and independent witness/transparency verification to avoid single-operator trust collapse. + +### Pass #4 implementation TODO block + +- [ ] Define `attestation_verifier_policy` (issuer allowlist, nonce TTL, claim schema, clock skew). +- [ ] Add signer migration plan with dual-sign period, verifier compatibility window, and rollback triggers. +- [ ] Add test vectors for stale nonce, wrong issuer, mismatched runtime measurement, and revoked key. +- [ ] Add end-to-end verification bundle format that includes receipt, attestation evidence, and verification transcript. + +--- + +## 2.

For CUA, we need: + +1. **Event streams** -- multiple actions per session, hash-chained together +2. **Rich evidence** -- frame hashes, DOM/A11y snapshots, diff regions +3. **Redaction metadata** -- blur rects, content-based PII markers +4. **Artifact references** -- links to stored frames/video, encrypted storage +5. **Gateway identity** -- build attestation, platform info, runtime type +6. **Session context** -- session/run IDs, policy mode + +Per the correction above: CUA extensions should be embedded under namespaced `metadata` within the existing `SignedReceipt` envelope, using a `receipt_profile` field to distinguish CUA-extended receipts from baseline receipts. + +### 1.3 Signer Abstraction + +The `Signer` trait (`crates/libs/hush-core/src/signing.rs`) already provides the right abstraction: + +```rust +pub trait Signer { + fn public_key(&self) -> PublicKey; + fn sign(&self, message: &[u8]) -> Result; +} +``` + +Current implementations: `Keypair` (in-memory Ed25519), `TpmSealedSeedSigner` (TPM2-backed). + +For CUA, additional implementations: `CoseSign1Signer`, `EnclaveProxySigner`, `ThresholdSigner`. + +--- + +## 2. Hash Chain Patterns + +### 2.1 Linear Hash Chains (prev_event_hash) + +Each event includes the hash of the previous event: + +``` +event[0].event_hash = H(canonicalize(event[0])) +event[0].prev_event_hash = H("genesis" || session_id) +event[n].prev_event_hash = event[n-1].event_hash +``` + +Properties: tamper-evident, append-only, verifiable ordering, O(n) verification. + +The canonical JSON of each event should include all evidence hashes but NOT raw evidence blobs, keeping the chain compact while binding evidence integrity. + +### 2.2 Merkle Tree Aggregation + +The existing `MerkleTree` in `hush-core` (`crates/libs/hush-core/src/merkle.rs`) implements RFC 6962-compatible Certificate Transparency-style trees with `leaf_hash = SHA256(0x00 || data)` and `node_hash = SHA256(0x01 || left || right)`. + +Two uses for CUA: +1. **Session checkpoint trees** -- periodically build Merkle tree from event hashes, sign root, provide O(log n) inclusion proofs +2. **Evidence bundle trees** -- Merkle root over all evidence artifacts for a single event + +### 2.3 RFC 9162 -- Certificate Transparency v2 + +RFC 9162 defines Signed Tree Heads, inclusion proofs, and consistency proofs. The Clawdstrike Merkle implementation already follows RFC 6962 conventions, making it CT-compatible at the tree-construction layer. Algorithm and signature-suite choices should be validated against the target log/verifier implementation profile. + +### 2.4 Recommended Approach + +Hybrid: linear hash chain for streaming verification + periodic Merkle checkpoints for O(log n) proofs + final session Merkle root for session-level attestation. + +--- + +## 3. Signing Formats + +### 3.1 COSE Sign1 (RFC 9052) + +CBOR-based signing envelope. Structure: `[protected_headers, unprotected_headers, payload, signature]`, CBOR tag 18. + +Advantages: binary compactness (often smaller than JSON in practice), standardized algorithm negotiation, SCITT compatibility, emerging COSE Hash Envelope draft for content-addressed payloads. + +Libraries: `coset` (Rust), `go-cose` (Go), `cose-js` (TypeScript), `pycose` (Python). + +### 3.2 JWS (RFC 7515) + +JSON-based signing. Structure: `{protected, payload, signature}` (all base64url). + +Advantages: native JSON ecosystem, wide library support, human-readable, compact serialization available. + +### 3.3 Comparison and Recommendation + +| Dimension | COSE Sign1 | JWS | +|-----------|-----------|-----| +| Wire size | Smaller (CBOR) | Larger (base64 JSON) | +| Ecosystem | Growing (IoT, SCITT, supply chain) | Mature (web, OAuth, JWT) | +| Browser verification | Requires CBOR library | Native JSON parsing | +| Clawdstrike alignment | New format | Closer to existing JSON receipts | + +**Recommendation**: Keep current Clawdstrike JSON receipt verification as the canonical baseline. Add COSE and/or JWS wrappers incrementally where interoperability demands it, with strict round-trip equivalence tests. + +### 3.4 Existing Signing vs COSE/JWS + +The current custom envelope (hex-encoded Ed25519 signatures in JSON) lacks algorithm negotiation, key ID headers, and standard verification tooling. For CUA, prioritize compatibility-first evolution: retain existing format support while layering standards-based envelopes behind explicit versioned profiles. + +--- + +## 4. Evidence Hashing + +### 4.1 SHA-256 for Frame Integrity + +Every frame capture hashed with SHA-256. Already used throughout Clawdstrike, compatible with transparency log conventions. + +### 4.2 Perceptual Hashing for Similarity + +pHash (DCT-based, robust against compression/resizing) and dHash (gradient-based, faster) provide "similar but not identical" detection. Output: 64-bit hash, Hamming distance for similarity. + +Use in CUA: cryptographic hash for tamper detection, perceptual hash for TOCTOU validation and audit deduplication. + +Libraries: `img_hash` (Rust), `imagehash` (Python), `sharp` (Node.js). + +### 4.3 DOM/A11y Tree Canonical Hashing + +Use RFC 8785 (JCS) canonicalization (already implemented in `crates/libs/hush-core/src/canonical.rs`) on normalized DOM/A11y snapshots, then SHA-256 the canonical form. Produces stable, deterministic, cross-language-verifiable hashes. + +### 4.4 Evidence Bundle Hashing + +Merkle root over all evidence artifacts for a single event. Allows individual artifact verification via inclusion proofs and selective redaction while proving remaining artifacts are intact. + +--- + +## 5. Redaction Design + +### 5.1 Redaction-Aware Hashing + +Core principle: **hash before redact, store redaction metadata alongside the hash**. Original frame -> SHA-256 hash in receipt -> apply redactions -> store redacted frame in artifacts -> store redaction metadata (rect, reason, detection_method, pre_redaction_hash) in receipt. + +### 5.2 Blur Rect Regions + +```json +"redactions": [{ + "kind": "blur_rect", + "reason": "password_field", + "rect": { "x": 120, "y": 220, "w": 540, "h": 60 }, + "detection_method": "dom_selector", + "pre_redaction_hash": "sha256:..." +}] +``` + +The `pre_redaction_hash` enables verifiers with the original to confirm redaction correctness. + +### 5.3 Content-Based PII Detection + +DOM selector matching (password inputs, credit card fields), OCR + regex (SSN/CC patterns in screenshots), A11y tree role matching (textbox in sensitive contexts). Detection method recorded for audit trail. + +### 5.4 Privacy-Preserving Evidence + +Frame-level encryption (encrypt entire frame with evidence encryption key), selective disclosure (Merkle tree over frame regions with redacted leaves replaced by hashes), time-locked encryption for delayed-access audit. + +--- + +## 6. Multi-Signature + +### 6.1 Gateway + Witness Model + +Gateway signs every event (key in TPM/Enclave). Witness independently validates and countersigns. Provides non-repudiation even if gateway is compromised. + +### 6.2 Threshold Signatures + +For high-assurance: FROST protocol (Schnorr threshold, compatible with Ed25519). MVP: multi-sig aggregation (multiple independent Ed25519 signatures, already partially supported by cosigner mechanism). + +### 6.3 Signature Aggregation for Bandwidth + +Checkpoint signatures (sign Merkle root every N events) recommended for MVP. Per-event signatures as configurable high-assurance mode. + +--- + +## 7. Artifact Storage + +### 7.1 Separation of Blob Storage from Receipt Ledger + +Receipts (metadata, append-only, compact, tamper-evident) stored separately from artifacts (evidence blobs, potentially encrypted, referenced by hash). Enables independent retention policies, storage tiers, selective retrieval, and independent encryption. + +### 7.2 Encryption Patterns + +**age encryption**: simple file encryption, X25519 keypairs, good for local/self-hosted. **KMS Envelope Encryption**: generate DEK locally, encrypt artifact with DEK (AES-256-GCM), encrypt DEK with KEK via KMS. Only 32-byte DEK goes to KMS (fast, cheap). Key rotation rotates KEK without re-encrypting artifacts. + +### 7.3 Content-Addressable Storage (CAS) + +Store artifacts by hash (`cas://sha256:abc123/pre_000001.png`). Automatic deduplication, free integrity verification, works with any backend. + +--- + +## 8. Append-Only Ledger + +### 8.1 Implementation Options + +| Option | Pros | Cons | +|--------|------|------| +| SQLite WAL | Single-file, ACID, fast reads | Single-writer | +| Append-only JSONL | Simplest, fast append | No indexing | +| Rekor (Sigstore) | Witnessing, inclusion proofs, public auditability | External dependency | +| PostgreSQL + triggers | Familiar, queryable | Not inherently tamper-evident | + +### 8.2 Sigstore Rekor Integration + +Rekor v2 (GA 2025) provides append-only tamper-evident log with tile-backed transparency, witnessing, inclusion/consistency proofs, REST API. Gateway submits signed receipt to Rekor, receives log index + inclusion proof + signed tree head, stores metadata in receipt. + +### 8.3 Compaction and Retention + +Checkpoint compaction (archive events before previous checkpoint), session finalization (final Merkle root + summary), configurable retention (receipts indefinitely, artifacts 30/90/365 days). + +--- + +## 9. Receipt Verification Flow + +### 9.1 Offline Verification + +Parse receipt -> validate schema version (fail-closed) -> compute canonical JSON -> verify primary signature -> verify cosigner -> verify hash chain links -> verify Merkle proofs. Already implemented for single receipts; extend for CUA chain and checkpoint verification. + +### 9.2 Online Verification + +Additionally: fetch STH from Rekor -> verify inclusion proof -> verify consistency -> check gateway key in discovery service. + +### 9.3 Key Discovery + +JWKS endpoint (`.well-known/jwks.json`) for MVP. DNS TXT records, transparency log key registration, and COSE key sets for later phases. + +--- + +## 10. Schema Versioning + +### 10.1 Compatibility Strategy + +Major version: breaking changes, verifier MUST reject unknown. Minor version: new optional fields, verifier SHOULD accept. Patch: clarifications only, always accepted. Use `$schema` URL for identification. + +### 10.2 Migration Path + +Receipt schema v1.0.0 (current single-action) -> CUA-extended receipts use `receipt_profile: "cua.v1"` field within existing `SignedReceipt` metadata. A CUA receipt with a single event and no evidence is equivalent to a v1.0.0 receipt. + +--- + +## 11. Comparison with Existing Attestation Formats + +### 11.1 in-toto / SLSA + +in-toto's subject/predicate model is analogous to receipt/evidence. SLSA provenance uses in-toto as delivery medium. Both are designed for software supply chain (build provenance), not real-time UI interaction. + +### 11.2 SCITT + +IETF working group defining transparent supply chain claims. Uses COSE Sign1, transparent registry (append-only ledger), and notarization. Architecture highly aligned with CUA receipt requirements. Draft expires April 2026. + +### 11.3 Comparison Table + +| Dimension | Clawdstrike CUA | in-toto/SLSA | SCITT | +|-----------|-----------------|--------------|-------| +| Domain | UI interaction attestation | Software supply chain | Generic supply chain | +| Signing | Ed25519 (COSE/JWS) | DSSE | COSE Sign1 | +| Evidence model | Frames, DOM, A11y, diffs | Build artifacts, SBOMs | Generic claims | +| Real-time | Yes | Batch | Batch | +| Redaction | First-class | N/A | Not specified | + +--- + +## 12.

Existing Clawdstrike Policy System + +### 1.1 Policy Schema (v1.1.0 / v1.2.0) + +The existing policy system is defined in `crates/libs/clawdstrike/src/policy.rs`. Policies are YAML documents with a strict schema version boundary: + +```rust +// policy.rs:22-24 +pub const POLICY_SCHEMA_VERSION: &str = "1.2.0"; +pub const POLICY_SUPPORTED_SCHEMA_VERSIONS: &[&str] = &["1.1.0", "1.2.0"]; +const MAX_POLICY_EXTENDS_DEPTH: usize = 32; +``` + +The `Policy` struct is the root configuration object: + +```rust +pub struct Policy { + pub version: String, // Schema version (must be in supported set) + pub name: String, + pub description: String, + pub extends: Option, // Base policy (ruleset name, file, URL, git ref) + pub merge_strategy: MergeStrategy, // Replace | Merge | DeepMerge (default) + pub guards: GuardConfigs, // 9 built-in guard configurations + pub custom_guards: Vec, + pub settings: PolicySettings, // fail_fast, verbose_logging, session_timeout_secs + pub posture: Option, // v1.2.0+: dynamic state machine +} +``` + +Key design decisions in the current system: + +1. **Fail-closed on version mismatch**: If the policy version is not in `POLICY_SUPPORTED_SCHEMA_VERSIONS`, parsing returns `Error::UnsupportedPolicyVersion`. This is a security boundary. +2. **`deny_unknown_fields` everywhere**: Serde rejects unknown YAML keys, preventing policy drift or injection of unvalidated configuration. +3. **Validation at load time**: `Policy::validate()` runs regex compilation, glob validation, placeholder resolution, and structural checks. Invalid policies never reach the guard evaluation stage. + +### 1.2 Guard Configuration (9 Built-in Guards) + +The `GuardConfigs` struct holds optional configuration for each guard. The 9 guards are evaluated in a fixed order defined by `PolicyGuards::builtin_guards_in_order()`: + +| Order | Guard | Config Field | Action Types Handled | +|-------|-------------------------|------------------------|---------------------| +| 1 | `ForbiddenPathGuard` | `forbidden_path` | FileAccess, FileWrite | +| 2 | `PathAllowlistGuard` | `path_allowlist` | FileAccess, FileWrite, Patch (v1.2.0) | +| 3 | `EgressAllowlistGuard` | `egress_allowlist` | NetworkEgress | +| 4 | `SecretLeakGuard` | `secret_leak` | FileWrite, Patch | +| 5 | `PatchIntegrityGuard` | `patch_integrity` | Patch | +| 6 | `ShellCommandGuard` | `shell_command` | ShellCommand | +| 7 | `McpToolGuard` | `mcp_tool` | McpTool | +| 8 | `PromptInjectionGuard` | `prompt_injection` | Custom("untrusted_text") | +| 9 | `JailbreakGuard` | `jailbreak` | Custom("untrusted_text") | + +Guards implement the `Guard` trait: + +```rust +#[async_trait] +pub trait Guard: Send + Sync { + fn name(&self) -> &str; + fn handles(&self, action: &GuardAction<'_>) -> bool; + async fn check(&self, action: &GuardAction<'_>, context: &GuardContext) -> GuardResult; +} +``` + +Actions are dispatched via the `GuardAction` enum: + +```rust +pub enum GuardAction<'a> { + FileAccess(&'a str), + FileWrite(&'a str, &'a [u8]), + NetworkEgress(&'a str, u16), + ShellCommand(&'a str), + McpTool(&'a str, &'a serde_json::Value), + Patch(&'a str, &'a str), + Custom(&'a str, &'a serde_json::Value), +} +``` + +The `Custom(&str, &Value)` variant is the extensibility point. The first argument is a type tag (e.g., `"untrusted_text"`), and the second is arbitrary JSON metadata. This variant is how CUA actions will be threaded through the existing guard pipeline. + +### 1.3 Policy Inheritance (`extends`) + +Policies support single-parent inheritance via the `extends` field. Resolution order: + +1. Built-in rulesets (`"default"`, `"strict"`, `"ai-agent"`, etc.) +2. `"clawdstrike:"` prefixed names (strip prefix, look up built-in) +3.

If `scan_before_access` is true, the async guard pipeline (VirusTotal, SafeBrowsing, Snyk) runs before the file is made available. This reuses the existing `AsyncGuardRuntime` infrastructure. + +### 4.3 Clipboard Policy + +Clipboard is a bidirectional data-flow channel that must be controlled in both directions: + +| Direction | Risk | Control | +|-----------|------|---------| +| Read (copy from app) | Data exfiltration | `clipboard.read: true/false`, size limits | +| Write (paste to app) | Injection (paste malicious content) | `clipboard.write: true/false`, `redact_before_paste` | + +When `redact_before_paste` is true, clipboard content passes through the redaction pipeline (Section 5) before being pasted.

Redaction Rules + +### 5.1 Pattern-Based Redaction + +Redaction removes sensitive content from screenshots and captured evidence. Two timing modes: + +**`before_capture` (recommended for production)**: +- Redaction runs before the screenshot is captured +- Uses DOM manipulation (inject CSS `filter: blur()` on sensitive elements) or overlay painting +- Captured frame never contains sensitive pixels +- Receipt evidence includes redaction manifest (what was redacted, which rule, element selector) + +**`post_capture`**: +- Screenshot captured first, then pixel regions are blurred/masked +- Higher fidelity for non-sensitive areas +- Requires storing unredacted frame temporarily (even if briefly) +- Redaction manifest records the regions (x, y, w, h) and the rule + +### 5.2 Redaction Rule Types + +```yaml +redaction: + always_redact: + # Regex patterns applied to visible text content + - pattern: "\\b\\d{3}-\\d{2}-\\d{4}\\b" + replacement: "[SSN-REDACTED]" + label: ssn + - pattern: "(?i)sk-[a-z0-9]{48}" + replacement: "[API-KEY-REDACTED]" + label: api_key + + content_triggers: + # DOM/accessibility selectors that trigger region redaction + - selector: "input[type=password]" + action: redact_region + label: password_input + - selector: "[data-sensitive=true]" + action: redact_region + label: app_marked_sensitive + - aria_role: "textbox" + aria_label_pattern: "(?i)ssn|social.security" + action: redact_region + label: aria_sensitive + + timing: before_capture +``` + +### 5.3 Redaction Provenance in Receipts + +Per the 07 document's corrections, redaction metadata must include provenance to prove what was removed. The receipt includes: + +```json +{ + "redactions": [ + { + "rule_label": "ssn", + "rule_hash": "sha256:abc123...", + "target_selector": "#ssn-field", + "region": {"x": 120, "y": 340, "w": 200, "h": 30}, + "content_hash_before": "sha256:def456...", + "content_hash_after": "sha256:789abc...", + "timing": "before_capture" + } + ] +} +``` + +The `rule_hash` is the SHA-256 of the canonical JSON serialization of the redaction rule, allowing verifiers to confirm which rule version was applied. The `content_hash_before` and `content_hash_after` allow verification that only the redacted regions changed. + +--- + +## 6. Human Approval Hooks + +### 6.1 Two-Person Rule + +Certain CUA actions require human approval before execution. This implements a "two-person rule" where the agent proposes an action and a human approves or denies it. + +Approval-required actions are declared in policy: + +```yaml +approval: + require_human_approval: + - action: file_upload + evidence_binding: true + - action: navigate + condition: "url_not_in_allowlist" + evidence_binding: true + - action: type + condition: "target_is_password_field" + evidence_binding: true + - action: click + condition: "target_matches_forbidden_ui" + evidence_binding: true +``` + +### 6.2 Evidence-Bound Approval + +Per the linter's correction, approval workflows must bind to immutable evidence digests to avoid TOCTOU attacks. When the agent requests approval: + +``` +1. Agent proposes: click(x=340, y=120) +2. Gateway captures pre-action state: + - frame_hash: sha256(current_screenshot) + - dom_hash: sha256(canonical_dom_snapshot) + - url: "https://app.example.com/settings" + - target_element: {tag: "button", text: "Delete Account", aria_role: "button"} +3. Gateway creates ApprovalRequest with evidence digest: + - evidence_digest = sha256(frame_hash || dom_hash || url || target_element_hash) +4. Human reviews evidence and approves/denies +5. On approval, gateway verifies current state still matches evidence_digest + - If state changed (different URL, different frame), approval is VOID + - Agent must re-request approval with new evidence +6.

Integration with Existing Guards + +### 9.1 Guard Dispatch for CUA Actions + +CUA actions flow through the existing `check_action()` pipeline.

Both must allow for the action to proceed. + +--- + +## 10. TOCTOU Prevention + +### 10.1 The Problem + +Time-of-check-to-time-of-use (TOCTOU) is the primary enforcement gap in CUA systems. The agent's view of the screen when it decides to act may differ from the actual state when the action executes. This creates two attack vectors: + +1. **UI Race**: A popup appears between policy check and click execution, causing the click to hit a different target +2. **Approval Staleness**: A human approves an action based on a screenshot, but the page changes before execution + +### 10.2 Pre-Action Assertions + +The gateway enforces pre-action assertions immediately before execution (after policy approval but before side effect): + +```rust +pub struct PreActionAssertions { + /// Hash of the current frame (must match what was policy-checked) + pub expected_frame_hash: Option, + /// URL must still match + pub expected_url: Option, + /// DOM element at target coordinates must match + pub expected_target: Option, + /// Accessibility node at target must match + pub expected_a11y_node: Option, +} + +pub struct ElementAssertion { + pub tag: String, + pub text_content: Option, + pub aria_role: Option, + pub aria_label: Option, + pub bounding_box: Option, +} + +impl Gateway { + pub async fn execute_with_assertions( + &self, + action: &CuaAction, + assertions: &PreActionAssertions, + ) -> Result { + // 1.

Verify frame hash + if let Some(expected) = &assertions.expected_frame_hash { + if current_frame_hash != *expected { + return Err(CuaError::AssertionFailed { + assertion: "frame_hash", + expected: expected.to_hex(), + actual: current_frame_hash.to_hex(), + }); + } + } + + // 3. Verify URL + if let Some(expected_url) = &assertions.expected_url { + let current_url = self.get_current_url().await?; + if current_url != *expected_url { + return Err(CuaError::AssertionFailed { + assertion: "url", + expected: expected_url.clone(), + actual: current_url, + }); + } + } + + // 4.

All assertions pass -- execute action atomically + self.execute_action(action).await + } +} +``` + +### 10.3 Frame Hash Pinning + +Frame hash pinning is the strongest TOCTOU prevention mechanism. The flow: + +``` +1. Agent receives screenshot (frame N) +2. Agent decides: click(340, 120) +3. Gateway computes frame_hash_N = sha256(frame_N) +4. Policy check runs with frame_hash_N as context +5. Policy approves action +6. Pre-execution: gateway captures frame_N+1, computes frame_hash_N+1 +7. If frame_hash_N != frame_hash_N+1: + - Action REJECTED (state changed since policy check) + - Agent receives new screenshot (frame N+1) + - Agent must re-decide and re-request +8. If hashes match: execute action +``` + +This creates a strict constraint: the screen must not change between when the agent sees it and when the action executes. For dynamic pages, this is overly strict. Relaxation strategies: + +| Strategy | Trade-off | +|----------|-----------| +| **Exact frame match** | Most secure but rejects on any pixel change (cursor blink, animation) | +| **Perceptual hash match** | Allows minor visual changes; configurable threshold (dHash hamming distance < 5) | +| **Target element match** | Only checks that the element at (x,y) matches; allows rest of page to change | +| **DOM subtree match** | Checks that the DOM subtree around the target element is unchanged | +| **URL + element match** | Checks URL hasn't changed and target element exists; most permissive | + +The policy controls which strategy is used: + +```yaml +safety: + toctou_strategy: target_element # exact_frame | perceptual | target_element | dom_subtree | url_element + perceptual_threshold: 5 # hamming distance for dHash (only if strategy=perceptual) +``` + +### 10.4 Approval TOCTOU + +For human-approved actions, the evidence-binding mechanism (Section 6.2) is the TOCTOU defense. The `evidence_digest` in the `ApprovalRequest` is recomputed before execution and compared to the approved digest. This is non-negotiable per the linter's correction. + +--- + +## 11.

Clawdstrike's typed guard pipeline is better suited for CUA because guards can encapsulate platform-specific logic (CDP queries, accessibility tree traversal). + +**Potential integration**: Use OPA as an optional "custom guard" for complex authorization rules that exceed what YAML config can express: + +```yaml +guards: + custom: + - package: clawdstrike-opa + config: + bundle_url: "https://policy.example.com/cua/bundle.tar.gz" + query: "data.cua.allow" +``` + +### 13.2 Cedar + +**Cedar** (AWS) is a formally verified policy language designed for authorization. + +| Dimension | Cedar | Clawdstrike | +|-----------|-------|-------------| +| **Language** | Cedar (custom, formally verified in Lean 4) | YAML config + Rust guards | +| **Model** | Principals, Actions, Resources, Context | GuardAction + GuardContext | +| **Decisions** | Permit / Forbid (Forbid always wins) | Allow / Deny / RequireConfirmation | +| **Verification** | Formal proofs (soundness, termination) | Property tests (proptest) | +| **Schema** | Entity type schemas | `deny_unknown_fields` + validation at load | +| **Performance** | ~0.01ms per decision (simple policies) | ~0.1-1ms per guard | + +**Key insight**: Cedar's "Forbid always wins" semantics align with Clawdstrike's fail-closed philosophy. Cedar's formal verification guarantees are attractive for high-assurance CUA deployments. + +**Practical consideration**: Cedar requires mapping CUA actions to the Principal-Action-Resource model: + +```cedar +// Cedar policy for CUA +permit ( + principal == Agent::"agent-123", + action == Action::"navigate", + resource +) when { + resource.url.host in AllowedDomains && + resource.url.scheme == "https" && + context.session.posture == "elevated" +}; + +forbid ( + principal, + action == Action::"file_upload", + resource +) unless { + context.approval.status == "approved" && + context.approval.evidence_digest == context.current_evidence_digest +}; +``` + +### 13.3 Casbin + +**Casbin** is a multi-model authorization library supporting ACL, RBAC, ABAC, and custom models. + +| Dimension | Casbin | Clawdstrike | +|-----------|--------|-------------| +| **Language** | Model config (PERM) + policies (CSV/DB) | YAML config + Rust guards | +| **Models** | ACL, RBAC, ABAC, custom | Guard pipeline (closest to ABAC) | +| **Runtime** | Go/Java/Python/Rust/etc. | Rust-first + TypeScript + Python + Wasm | +| **Performance** | Varies by model; RBAC ~0.1ms | ~0.1-1ms per guard | +| **Extensibility** | Custom model definitions | Custom guard trait | + +**Key insight**: Casbin's model flexibility is powerful but adds complexity.

Conclusion + +The Clawdstrike policy engine provides a strong foundation for CUA enforcement. The existing guard pipeline, typed action dispatch, inheritance system, posture model, and fail-closed philosophy are directly applicable. CUA-specific extensions should be introduced as a new `ComputerUseGuard` that handles `Custom("cua_*")` actions, keeping the existing guard evaluation flow intact. + +The three response modes (observe/guardrail/fail_closed) enable graduated rollout. Evidence-bound human approval workflows and TOCTOU prevention via pre-action assertions address the unique challenges of UI automation. Redaction and data-flow controls protect sensitive information throughout the CUA session lifecycle. + +By mapping CUA actions into existing guard semantics first and introducing CUA-specific logic through the established extensibility points (`Custom` action variant, custom guards, policy inheritance), the CUA gateway avoids creating a parallel policy universe while gaining the UI-specific safety properties that external policy engines cannot provide. diff --git a/docs/roadmaps/cua/research/09-ecosystem-integrations.md b/docs/roadmaps/cua/research/09-ecosystem-integrations.md new file mode 100644 index 000000000..fa3a361d9 --- /dev/null +++ b/docs/roadmaps/cua/research/09-ecosystem-integrations.md @@ -0,0 +1,96 @@ +# 09 Ecosystem Integrations (OpenAI / Claude / OpenClaw / trycua) + +## Scope + +Define how Clawdstrike integrates with popular computer-use ecosystems without fragmenting policy, receipt, or verifier semantics. + +Primary targets: + +- OpenAI computer-use tool path. +- Claude computer-use tool path. +- Existing `@clawdstrike/openclaw` plugin path. +- `trycua/cua` as runtime/backend candidate. + +## Core integration position + +- Clawdstrike owns the canonical contract for policy events, outcomes, audit metadata, and receipt semantics. +- External libraries/providers are translated into that contract through adapters. +- External runtime/framework integration must not redefine trust roots, verifier order, or receipt compatibility rules. + +## Pass #11 reviewer notes (2026-02-18) + +- REVIEW-P11-CORRECTION: Integrate provider ecosystems as adapter layers, not as policy/verifier sources of truth. +- REVIEW-P11-GAP-FILL: Add canonical CUA action/event contract in adapter core before adding provider-specific translators. +- REVIEW-P11-CORRECTION: Require conformance fixtures across providers so equivalent CUA actions produce equivalent policy outcomes. + +## Design constraints + +- Fail closed on unknown provider action types, wrapper versions, and missing required fields. +- Keep baseline `SignedReceipt` compatibility and CUA metadata profile guarantees. +- Ensure event and outcome parity across provider adapters for equivalent interactions. +- Preserve deterministic reason codes and audit trails across all adapters. + +## Integration tracks + +### Track A: Canonical adapter-core CUA contract + +- Extend adapter-core event model to support CUA-native flow surfaces: + -

files changed/created in passes #11--#13 (~39 files, ~3000 lines) +**Branch:** `feat/cua` + +--- + +## Critical Issues (must fix before merge) + +### C1. `remote.session_share` missing from PolicyEventType (Rust) and EventType (TypeScript) + +**Rust:** `crates/services/hushd/src/policy_event.rs` -- The `PolicyEventType` enum defines 6 CUA event types (`RemoteSessionConnect`, `RemoteSessionDisconnect`, `RemoteSessionReconnect`, `InputInject`, `ClipboardTransfer`, `FileTransfer`) but does NOT include `remote.session_share`. The `ComputerUseGuard` default config (`crates/libs/clawdstrike/src/guards/computer_use.rs:52`) includes `"remote.session_share"` as a valid allowed action, and the `RemoteDesktopSideChannelGuard` (`remote_desktop_side_channel.rs:95`) handles `"remote.session_share"` in its `handles()` method. However, there is no `PolicyEventType::SessionShare` variant, so any policy event with `eventType: "remote.session_share"` will deserialize to `PolicyEventType::Other("remote.session_share")` and be **rejected by `map_policy_event()`** at line 662 with `"unsupported eventType"`. This means the session_share pathway is dead at the hushd layer. + +**TypeScript:** `packages/adapters/clawdstrike-adapter-core/src/types.ts:24-38` -- The `EventType` union similarly lacks `'remote.session_share'`. The `PolicyEventFactory` has no `createCuaSessionShareEvent()` method. + +**Impact:** Session sharing policy evaluation will fail closed at the daemon/adapter boundary even though the guard layer supports it. This is either a deliberate omission (session_share only works at the guard layer, not via hushd) or a gap. If deliberate, it should be documented. If not, it needs a new enum variant + mapping arm + factory method. + +**Recommendation:** Add `SessionShare` variant to `PolicyEventType` with string `"remote.session_share"`, add the mapping arm in `map_policy_event()`, add `'remote.session_share'` to the TS `EventType` union, and add `createCuaSessionShareEvent()` to `PolicyEventFactory`. Alternatively, document this as intentionally unsupported at the daemon layer. + +### C2. `InputInjectionCapabilityGuard` silently allows when `input_type` field is absent + +**File:** `crates/libs/clawdstrike/src/guards/input_injection_capability.rs:110-126` + +When the `input_type` field is not present in the JSON data, the guard falls through and allows the action (line 148). This is confirmed by the test `test_allows_without_input_type_field` at line 226. In a security-critical guard for input injection, **missing input type should be denied, not allowed**, especially in a fail-closed system. An attacker could bypass the input type allowlist by simply omitting the field. + +**Recommendation:** Change the behavior when `input_type` is missing to deny the action, at least when the guard is in an active enforcement mode. At minimum, log a warning. + +### C3. `RemoteDesktopSideChannelGuard` wildcard arm allows unknown custom types + +**File:** `crates/libs/clawdstrike/src/guards/remote_desktop_side_channel.rs:179` + +The match statement's wildcard arm `_ => GuardResult::allow(&self.name)` allows any custom action type that reaches the guard but doesn't match the three known channels. While the `handles()` method (line 86-97) should filter to only the three known types, if `handles()` is ever bypassed (e.g., direct `check()` call), unknown types would be silently allowed. The `handles()` + `check()` contract is not enforced at the type level. + +**Impact:** Low in current architecture (the engine calls `handles()` first), but violates the fail-closed principle. Consider returning a deny result for the wildcard arm. + +--- + +## Warnings (should fix) + +### W1. New CUA guards use `or_else` merge (last-wins) instead of deep merge + +**File:** `crates/libs/clawdstrike/src/policy.rs:326-337` + +The three new guard configs (`computer_use`, `remote_desktop_side_channel`, `input_injection_capability`) use the simple `child.clone().or_else(|| self.clone())` merge strategy (lines 326-337), which means the child completely replaces the base config. This differs from guards like `forbidden_path`, `egress_allowlist`, and `secret_leak` which support `additional_*`/`remove_*` merge semantics. This is acceptable for initial implementation but limits composability. For example, a child policy cannot selectively add one more allowed action to `computer_use.allowed_actions` without restating the entire list. + +### W2. `ComputerUseGuard::handles()` uses prefix matching, creating ambiguity + +**File:** `crates/libs/clawdstrike/src/guards/computer_use.rs:107` + +The `handles()` method matches any action starting with `"remote."` or `"input."`. This means: +- `remote.clipboard` and `remote.file_transfer` are claimed by BOTH `ComputerUseGuard` and `RemoteDesktopSideChannelGuard`. +- `remote.session_share` is claimed by BOTH `ComputerUseGuard` and `RemoteDesktopSideChannelGuard`. + +When both guards are active (as in the CUA rulesets), the engine will evaluate both guards for these actions. The `ComputerUseGuard` checks the allowlist, and the `RemoteDesktopSideChannelGuard` checks channel-specific policies. This dual evaluation is likely intentional (defense in depth), but it should be documented explicitly. If `ComputerUseGuard` is in `FailClosed` mode and the action is not in its allowlist, the action will be denied even if the side channel guard would allow it. + +### W3. `CuaEventData.extra` captures `type` discriminator field on roundtrip + +**File:** `crates/services/hushd/src/policy_event.rs:401-427` + +The `CuaEventData` struct uses `#[serde(flatten)] pub extra: serde_json::Map`. During deserialization, the `type` discriminator (which is manually handled in `PolicyEventData::Deserialize`) is already consumed, but during serialization, `serialize_typed_data()` re-inserts `"type": "cua"`. On a second roundtrip deserialization, the `"type"` field will end up in `extra` because `CuaEventData` doesn't have a `type` field -- it's handled at the `PolicyEventData` level. The roundtrip test at line 895-927 acknowledges this by comparing field-by-field rather than using `assert_eq!` on the whole struct. + +**Impact:** Not a security issue, but this asymmetry could cause confusion in downstream consumers that inspect `extra`. Consider explicitly skipping `"type"` from `extra` during deserialization, or document the behavior. + +### W4. `FileEventData.operation` is `Option` in Rust but required in TypeScript + +**File:** `crates/services/hushd/src/policy_event.rs:328` vs `packages/adapters/clawdstrike-adapter-core/src/types.ts:65` + +In Rust, `FileEventData.operation` is `Option`. In TypeScript, it's `operation: 'read' | 'write'` (required, not optional). This parity difference could cause validation failures when Rust-serialized events are consumed by TypeScript code, or vice versa. + +### W5. `CommandEventData` has `workingDir` in TypeScript but not in Rust + +**File:** `packages/adapters/clawdstrike-adapter-core/src/types.ts:72` vs `crates/services/hushd/src/policy_event.rs:356-362` + +The TypeScript `CommandEventData` includes an optional `workingDir` field that doesn't exist in the Rust struct. This is a minor parity gap. + +### W6. `CuaEventData.cuaAction` naming convention differs between Rust and TS factory + +The Rust side uses the raw `cua_action` value (e.g., `"connect"`, `"disconnect"`, `"reconnect"`), while the TypeScript `PolicyEventFactory` uses dotted names (e.g., `"session.connect"`, `"session.disconnect"`, `"session.reconnect"`, `"input.inject"`, `"clipboard"`, `"file_transfer"`). These are semantically different strings for the same operations. While the guards don't inspect `cua_action` directly (they use the `eventType` / custom_type from the outer action), any downstream consumer comparing `cuaAction` across languages will see mismatches. + +**Files:** +- TypeScript: `policy-event-factory.ts:99` (`session.connect`) vs Rust test: `policy_event.rs:770` (`connect`) + +--- + +## Observations (informational) + +### O1. Guard ordering is well-defined and consistent + +`crates/libs/clawdstrike/src/policy.rs:1614-1631` -- The `builtin_guards_in_order()` method returns guards in a stable, documented order. The three new CUA guards are appended at positions 10-12 (computer_use, remote_desktop_side_channel, input_injection_capability), after all pre-existing guards. This means filesystem/network/secret guards run first, which is correct for defense-in-depth. + +### O2. All YAML rulesets use schema version 1.2.0 + +All three CUA rulesets (`remote-desktop.yaml`, `remote-desktop-strict.yaml`, `remote-desktop-permissive.yaml`) correctly use `version: "1.2.0"`. The base `ai-agent.yaml` uses `version: "1.1.0"`, which is valid because the extends mechanism allows version upgrades from child to base. + +### O3. `deny_unknown_fields` applied consistently + +All three guard config structs (`ComputerUseConfig`, `RemoteDesktopSideChannelConfig`, `InputInjectionCapabilityConfig`) use `#[serde(deny_unknown_fields)]`, which prevents silent data loss during deserialization. + +### O4. Duplicate rulesets in `crates/libs/clawdstrike/rulesets/` and `rulesets/` + +The three CUA YAML files exist in both `rulesets/` (workspace root) and `crates/libs/clawdstrike/rulesets/` (for `include_str!`). Content is identical. This is the established pattern in the codebase. A sync test exists at `policy.rs:2121-2160` that validates disk files match `RuleSet::list()`. + +### O5. CI workflow updated with CUA harness verification + +`.github/workflows/ci.yml:886-901` -- The Python SDK job now runs 15 CUA research verification harnesses.

Unknown custom types in `ComputerUseGuard` are denied in `FailClosed` mode, warned in `Guardrail`. **Exception:** `InputInjectionCapabilityGuard` allows missing `input_type` (C2); `RemoteDesktopSideChannelGuard` wildcard arm allows (C3, low risk). + +- [x] **Rust/TS parity**: CuaEventData fields are aligned between languages. EventType variants match for the 14 defined types. **Exception:** `remote.session_share` missing from both (C1); `FileEventData.operation` optionality differs (W4); `cuaAction` values differ in convention (W6). + +- [x] **Guard ordering**: Guards execute in consistent, documented order via `builtin_guards_in_order()`. New CUA guards are appended at the end (positions 10-12). The order is fixed in the array literal (O1). + +- [x] **Serde correctness**: All configs use `deny_unknown_fields`. `CuaEventData` uses `flatten` for extensibility with snake_case aliases (O3). Minor roundtrip asymmetry with `type` field in `extra` (W3). + +- [x] **No secret leaks**: Guard evidence/details contain only action type, mode, channel name, and size information. No raw credentials or sensitive data are exposed in `GuardResult` details. + +- [x] **Policy inheritance**: Extends chains resolve correctly. `remote-desktop` extends `ai-agent`; `remote-desktop-strict` and `remote-desktop-permissive` extend `remote-desktop`. Circular dependency detection uses visited set with depth limit of 32. The `ai-agent` -> `remote-desktop` version upgrade (1.1.0 -> 1.2.0) is handled correctly by the merge logic. + +- [x] **Test coverage**: All three guards have allow/deny/edge-case tests. All error codes are tested in hushd policy events. TypeScript factory and fixture tests cover all 6 CUA event types. **Gaps:** No engine-level integration test with `remote-desktop-strict` that verifies actual deny behavior; no session_share tests in hushd or TS layers. + +- [x] **Clippy/lint**: `#![allow(clippy::expect_used, clippy::unwrap_used)]` is used in test files only. No suppressed warnings in production code. + +- [x] **YAML schema versions**: All CUA rulesets use `version: "1.2.0"` correctly. The base `ai-agent.yaml` uses `version: "1.1.0"`, which is valid. + +- [x] **Documentation accuracy**: `fixtures/README.md` lists all new fixture groups (entries 6-19). The `RuleSet::list()` includes all 3 new rulesets and a sync test validates disk<->registry consistency. + +--- + +## Summary + +The implementation is solid with well-structured guards, proper serde handling, and good test coverage. Three critical issues were identified: + +1. **C1** is the most significant: `remote.session_share` has guard support but no event type mapping, creating a dead pathway at the daemon/adapter boundary. +2. **C2** is a security concern: missing `input_type` should deny, not allow, for a security guard. +3. **C3** is low risk but violates fail-closed principles. + +The warnings are mostly parity gaps and merge strategy limitations that should be addressed before GA but are acceptable for the current development phase. The test suite is comprehensive but could benefit from engine-level deny tests using the strict CUA ruleset. diff --git a/docs/roadmaps/cua/research/pass8-verifier-harness-report.json

The following matrix maps trycua capabilities to each. + +| trycua Capability | Canonical Flow Surface | Status | Notes | +|-------------------|----------------------|--------|-------| +| VM session start | `connect` | **Partial** | trycua manages VM lifecycle but does not emit a structured connect event. Connector must synthesize `remote.session.connect` from VM start callbacks. | +| VM session stop | `disconnect` | **Partial** | VM stop/teardown exists but no structured disconnect event. Connector must map VM lifecycle hooks to `remote.session.disconnect`. | +| VM reconnect / resume | `reconnect` | **Unsupported** | No explicit reconnect primitive. VM sessions are either running or stopped. Connector must fail closed on reconnect attempts or synthesize from VM state transitions. | +| Click / type / mouse | `input` | **Compatible** | Core action types (click, type, mouse_move) map directly to `input.inject` with `cuaAction` field. Coordinate and text payloads translate cleanly. | +| Shared clipboard read | `clipboard_read` | **Partial** | Host-sandbox clipboard sharing exists but is implicit (not a discrete API call). Connector must intercept clipboard sync events and map to `remote.clipboard`. | +| Shared clipboard write | `clipboard_write` | **Partial** | Same as clipboard_read -- clipboard write is bidirectional sync, not a discrete write operation. Connector must infer direction from context. | +| File transfer (host->sandbox) | `file_transfer_upload` | **Partial** | File transfer exists in the Computer SDK but lacks structured metadata (path, size, hash). Connector must enrich events with evidence fields for `remote.file_transfer`. | +| File transfer (sandbox->host) | `file_transfer_download` | **Partial** | Same limitations as upload. Additionally, egress_allowlist guard cannot be applied without connector-provided destination metadata. | + +### Status Legend + +- **Compatible:** trycua capability maps cleanly to canonical flow surface with minimal translation. +- **Partial:** trycua has the capability but lacks structured event emission. Connector must synthesize/enrich canonical events. +- **Unsupported:** No trycua equivalent. Connector must fail closed. + +## Fail-Closed Boundaries + +The connector must enforce fail-closed semantics for: + +1. **Unsupported flows:** Any trycua action that cannot be mapped to one of the 8 canonical flow surfaces must produce `ADC_FLOW_UNKNOWN` and deny the action. + +2. **Missing evidence fields:** trycua does not emit structured evidence (paths, hashes, coordinates as metadata). If a guard requires evidence that the connector cannot extract from the trycua action stream, the connector must deny with `ADC_GUARD_RESULT_MALFORMED`. + +3. **Unknown action types:** trycua may introduce new action types (e.g., `agent-browser`, `agent-device` for iOS/Android). Any action type not in the connector's known mapping must fail closed with `TCC_ACTION_UNKNOWN`. + +4. **Reconnect flow:** trycua has no reconnect primitive. Any attempt to map a trycua event to the `reconnect` flow surface must fail closed with `TCC_FLOW_UNSUPPORTED` unless the connector can deterministically synthesize reconnect semantics from VM state transitions. + +5. **Clipboard direction ambiguity:** trycua's shared clipboard is bidirectional without explicit direction. If the connector cannot determine read vs. write direction, it must fail closed with `TCC_DIRECTION_AMBIGUOUS`. + +6. **Session identity:** trycua VM sessions may not carry stable session identifiers across the lifecycle. If `audit_ref` cannot be populated with a stable session ID, the connector must fail closed with `ADC_MISSING_POLICY_REF`. + +## Integration Architecture + +``` +trycua/cua Action Stream + | + v + +------------------+ + | trycua Connector | <-- Adapter layer (NOT trust-root) + | | + | - Action mapping | + | - Evidence enrich | + | - Direction infer | + | - Fail-closed | + +------------------+ + | + v + Canonical Policy Event + (eventType, cuaAction, direction, evidence) + | + v + +------------------+ + | Adapter Core | <-- Clawdstrike canonical contract + | - Guard eval | + | - Policy engine | + | - Receipt signing | + | - Audit pipeline | + +------------------+ +``` + +The connector is a **translation layer** that: +- Receives raw trycua action streams +- Maps actions to canonical flow surfaces +- Enriches events with required evidence fields +- Infers direction where trycua is ambiguous +- Fails closed on any unmappable action or missing evidence +- Emits canonical policy events consumed by adapter-core + +The connector does NOT: +- Define or modify trust roots +- Override verifier order +- Issue or modify receipts +- Bypass guard evaluation + +## Incompatibilities + +### Structural Incompatibilities + +1. **No structured event model:** trycua emits raw action streams, not structured policy events. The entire event schema must be constructed by the connector, increasing surface area for translation errors. + +2. **No native policy integration:** trycua has no concept of policy evaluation, guard checks, or receipt signing. All policy semantics are external to trycua. + +3. **Implicit clipboard semantics:** Bidirectional clipboard sync without explicit read/write direction forces the connector to infer direction, which may be unreliable. + +4. **No reconnect primitive:** The canonical contract requires `reconnect` as a distinct flow surface. trycua only has binary session state (running/stopped). + +5. **Missing file transfer metadata:** trycua file operations lack structured metadata (source path, destination path, file hash, file size) required by `forbidden_path` and `remote_desktop_side_channel` guards. + +### Provider Conformance Gaps + +6. **No canonical intent mapping:** trycua does not use the provider conformance suite's intent vocabulary (click_element, type_text, navigate_url, etc.). The connector must maintain its own intent-to-action mapping. + +7. **Streaming vs. request/response:** trycua's async streaming model differs from the request/response model assumed by the canonical adapter contract. The connector must buffer and correlate streaming events into discrete flow surface evaluations. + +### Operational Gaps + +8. **Session identity stability:** trycua VMs may not provide stable session identifiers suitable for `audit_ref` population across policy evaluations within the same logical session. + +9. **Evidence handoff:** trycua does not provide evidence bundles (screenshots, DOM snapshots, input logs) in a format consumable by Clawdstrike guards. The connector must either extract evidence from the action stream or explicitly reject evidence-dependent guard evaluations. + +## Connector Error Codes + +| Code | Meaning | +|------|---------| +| `TCC_ACTION_UNKNOWN` | trycua action type not in connector mapping | +| `TCC_FLOW_UNSUPPORTED` | trycua has no equivalent for canonical flow surface | +| `TCC_DIRECTION_AMBIGUOUS` | Cannot determine clipboard/transfer direction | +| `TCC_EVIDENCE_MISSING` | Required evidence fields not extractable from trycua stream | +| `TCC_SESSION_ID_MISSING` | Cannot populate stable session identifier for audit_ref | + +These connector-specific codes are emitted before canonical adapter-core evaluation. They are distinct from `ADC_*` codes which are emitted by the adapter-core contract itself. + +## Recommendations + +1. **Start with `input` flow:** This is the only fully compatible flow surface. Build and validate the connector for click/type/mouse actions first. + +2. **Session lifecycle next:** Implement connect/disconnect mapping from VM lifecycle hooks. Accept the limitation that reconnect will fail closed until trycua adds explicit reconnect semantics. + +3. **Clipboard requires investigation:** The bidirectional clipboard sync needs deeper analysis. Consider requiring explicit clipboard API calls rather than relying on OS-level sync detection. + +4. **File transfer requires enrichment:** The connector must add metadata extraction (path, hash, size) for file operations. This is a significant implementation effort. + +5. **Do not attempt evidence handoff initially:** Guards that require evidence bundles (screenshots, DOM state) should be explicitly unsupported in the connector's first iteration, failing closed. + +## References + +- Canonical contract: `docs/roadmaps/cua/research/canonical_adapter_cua_contract.yaml` +- Provider conformance: `docs/roadmaps/cua/research/provider_conformance_suite.yaml` +- Integration strategy: `docs/roadmaps/cua/research/09-ecosystem-integrations.md` +- Connector suite: `docs/roadmaps/cua/research/trycua_connector_suite.yaml` +- Connector fixtures: `fixtures/policy-events/trycua-connector/v1/cases.json` +- trycua/cua: https://github.com/trycua/cua diff --git a/docs/roadmaps/cua/research/trycua_connector_report.json b/docs/roadmaps/cua/research/trycua_connector_report.json new file mode 100644 index 000000000..1c166efc1 --- /dev/null +++ b/docs/roadmaps/cua/research/trycua_connector_report.json @@ -0,0 +1,188 @@ +{ + "results": [ + { + "actual": { + "canonical": { + "data": { + "cuaAction": "click", + "direction": null + }, + "eventType": "input.inject", + "flow": "input" + }, + "result": "pass" + }, + "expected": { + "canonical": { + "data": { + "cuaAction": "click", + "direction": null + }, + "eventType": "input.inject", + "flow": "input" + }, + "result": "pass" + }, + "id": "trycua_click_maps_to_input_inject", + "ok": true + }, + { + "actual": { + "canonical": { + "data": { + "cuaAction": "type", + "direction": null + }, + "eventType": "input.inject", + "flow": "input" + }, + "result": "pass" + }, + "expected": { + "canonical": { + "data": { + "cuaAction": "type", + "direction": null + }, + "eventType": "input.inject", + "flow": "input" + }, + "result": "pass" + }, + "id": "trycua_type_maps_to_input_inject", + "ok": true + }, + { + "actual": { + "canonical": { + "data": { + "cuaAction": "vm_start", + "direction": "outbound" + }, + "eventType": "remote.session.connect", + "flow": "connect" + }, + "result": "pass" + }, + "expected": { + "canonical": { + "data": { + "cuaAction": "vm_start", + "direction": "outbound" + }, + "eventType": "remote.session.connect", + "flow": "connect" + }, + "result": "pass" + }, + "id": "trycua_vm_start_maps_to_connect", + "ok": true + }, + { + "actual": { + "canonical": { + "data": { + "cuaAction": "vm_stop", + "direction": null + }, + "eventType": "remote.session.disconnect", + "flow": "disconnect" + }, + "result": "pass" + }, + "expected": { + "canonical": { + "data": { + "cuaAction": "vm_stop", + "direction": null + }, + "eventType": "remote.session.disconnect", + "flow": "disconnect" + }, + "result": "pass" + }, + "id": "trycua_vm_stop_maps_to_disconnect", + "ok": true + }, + { + "actual": { + "error_code": "TCC_DIRECTION_AMBIGUOUS", + "result": "fail" + }, + "expected": { + "error_code": "TCC_DIRECTION_AMBIGUOUS", + "result": "fail" + }, + "id": "trycua_clipboard_sync_direction_ambiguous_fails_closed", + "ok": true + }, + { + "actual": { + "error_code": "TCC_EVIDENCE_MISSING", + "result": "fail" + }, + "expected": { + "error_code": "TCC_EVIDENCE_MISSING", + "result": "fail" + }, + "id": "trycua_file_copy_evidence_missing_fails_closed", + "ok": true + }, + { + "actual": { + "error_code": "TCC_ACTION_UNKNOWN", + "result": "fail" + }, + "expected": { + "error_code": "TCC_ACTION_UNKNOWN", + "result": "fail" + }, + "id": "trycua_unknown_action_fails_closed", + "ok": true + }, + { + "actual": { + "error_code": "TCC_FLOW_UNSUPPORTED", + "result": "fail" + }, + "expected": { + "error_code": "TCC_FLOW_UNSUPPORTED", + "result": "fail" + }, + "id": "trycua_reconnect_flow_unsupported_fails_closed", + "ok": true + }, + { + "actual": { + "canonical": { + "data": { + "cuaAction": "screenshot", + "direction": "read" + }, + "eventType": "remote.clipboard", + "flow": "clipboard_read" + }, + "result": "pass" + }, + "expected": { + "canonical": { + "data": { + "cuaAction": "screenshot", + "direction": "read" + }, + "eventType": "remote.clipboard", + "flow": "clipboard_read" + }, + "result": "pass" + }, + "id": "trycua_screenshot_maps_to_clipboard_read", + "ok": true + } + ], + "suite": "docs/roadmaps/cua/research/trycua_connector_suite.yaml", + "summary": { + "failed": 0, + "passed": 9, + "total": 9 + } +} diff --git a/docs/roadmaps/cua/research/trycua_connector_suite.yaml b/docs/roadmaps/cua/research/trycua_connector_suite.yaml new file mode 100644 index 000000000..db1da9acc --- /dev/null +++ b/docs/roadmaps/cua/research/trycua_connector_suite.yaml @@ -0,0 +1,182 @@ +suite_id: trycua-connector-suite +suite_version: "1.0.0" +updated_at: "2026-02-18T00:00:00Z" + +description: > + Defines the trycua/cua connector compatibility matrix against the canonical + adapter-core CUA contract.
