API Polyfill Guard: Global prototype objects evaluated. Zero unauthorized framework method overrides detected. Loop Monotonicity: Micro‑timing loops processed. Compilation speeds match authentic bare‑metal devices. Background Throttling: Execution thread verified as active. Tab context is not in a frozen background state. Entropy Verification: Math.random() values display natural distribution bounds with no fixed‑seed patterns. Replay Mitigation: Ephemeral timestamps validated to prevent replay of historical execution states. Hardware Clock Linearity: Date.now() monitored. System epoch increments match continuous hardware timing. Clock Desync Monitor: Client‑side timing variation remains within safe operational bounds. DOM Tree Integrity: Root DOM structure validated. No unauthorized mutations detected. Paint Timing Analysis: Rendering cycle durations match expected hardware refresh intervals. Script Injection Shield: Dynamic evaluation sinks monitored. No rogue script insertion attempts detected. JS Engine Profile: Compiler and runtime behaviors match standard user‑agent engine characteristics. Sandbox Isolation: No reliable indicators of headless or stealth automation environments detected. Virtualization Scanner: Instruction pipeline responses confirm execution on native consumer hardware. RDP Frame Tracker: No indicators of remote desktop or virtual terminal stream behavior detected. NoScript Execution Block: Script execution path remains fully active with no runtime blockers. Canvas Protection Monitor: Canvas rasterization channels verified clear of artificial noise or pixel spoofing. WebGL Layer Validation: Graphics context confirms unmasked, direct hardware rendering paths. Privacy Extension Overrides: Browser privacy features detected that modify or mask certain APIs. Informational only; does not indicate a malfunction. Container Co‑Existence: External layout tree validated. No unauthorized wrapper script containers appended. Turnstile Collision Check: Runtime namespace scanned. No interference from Cloudflare Turnstile assets. Turnstile does not automatically cause this check to fail. reCAPTCHA Telemetry Monitor: Browser privacy protections would block CAPTCHA‑style telemetry if such scripts were present. No CAPTCHA scripts detected. reCAPTCHA Interference Check: Execution frames verified clear of CAPTCHA scripts. Browser privacy features would interfere with CAPTCHA tracking hooks if loaded. Contextual Query Guard: Action arguments scanned. No malicious or injection‑style patterns detected. Malformed Input Filter: Input structure validated against baseline application threat models. --- How HV3 Works HV3 is a browser‑side integrity and environment‑verification system. It evaluates whether the current execution environment behaves like a real, human‑operated browser by analyzing: • hardware‑level signals • timing behavior • entropy sources • DOM integrity • graphics pipeline behavior • privacy‑layer interference • script execution context • input structure • action‑string semantics HV3 does not fingerprint users, track them, or send data anywhere. All checks run locally and produce a score between 0.30 and 0.90, with optional Proof‑of‑Work boosting up to 0.95. The system is designed to detect: • automation • synthetic environments • replay attacks • timing manipulation • script injection • virtualization • stealth headless modes • privacy‑layer interference patterns It is not a CAPTCHA. It is not a fingerprinting system. It is a local integrity evaluator. --- How to Interpret Your Score 0.90 (Raw Score) This is the highest legitimate human score. It means: • no automation detected • no timing anomalies • no DOM tampering • no replay patterns • no synthetic entropy • no suspicious action strings • no headless indicators • no virtualization flags 0.93–0.95 (With PoW) This indicates the browser successfully completed a Proof‑of‑Work challenge. This is optional and only increases confidence. 0.70–0.89 Indicates mild interference or privacy‑layer behavior. Usually caused by: • privacy extensions • anti‑tracking • canvas noise • WebGL masking • script isolation Not necessarily a problem. 0.50–0.69 Indicates moderate interference or partial automation signals. 0.30–0.49 Indicates strong automation or environmental anomalies. --- Why Checks Pass or Fail PASS means: • the browser behaves like a normal human‑operated environment • APIs are unmodified • timing is natural • entropy is natural • graphics pipeline is intact • no automation signatures detected FAIL means: A check detected behavior that could indicate: • privacy protections • anti‑tracking • script blocking • canvas noise • WebGL masking • virtualization • remote desktop • automation frameworks • modified global objects A FAIL does not always mean something is wrong. Many FAILs are caused by privacy features, not automation. UNKNOWN means: • the browser does not expose the required API • the environment blocks the measurement • the check cannot reliably determine a result This is normal in Safari, Firefox, Brave, and mobile browsers. --- Common Causes of False Positives HV3 is intentionally conservative. False positives usually come from: 1. Privacy Extensions • uBlock Origin • Privacy Badger • Ghostery • DuckDuckGo extension These modify or block APIs. 2. Built‑in Browser Privacy Features • Firefox Enhanced Tracking Protection • Safari Intelligent Tracking Prevention • Brave Shields • Edge Tracking Prevention These can trigger FAILs in: • Privacy Extension Overrides • reCAPTCHA Telemetry Monitor • reCAPTCHA Interference Check 3. Canvas or WebGL Protection Browsers or extensions may: • add noise • mask GPU vendor strings • block WebGL contexts 4. Virtualization or Remote Desktop Even legitimate remote sessions can trigger: • Virtualization Scanner • RDP Frame Tracker 5. Sandboxed or Embedded Environments Running inside: • iframes • WebViews • embedded browsers can cause UNKNOWN or FAIL results. --- FAQ Q: Does HV3 track me or send data anywhere? No. All checks run locally in your browser. No data leaves your device. Q: Why do privacy‑related checks fail even though I’m not using automation? Because modern browsers include anti‑tracking features that mimic automation‑like interference patterns. Q: Why does my score stay high even when some checks fail? Privacy‑related FAILs are informational only and do not reduce your score. Q: Can HV3 misidentify a real user as a bot? HV3 is designed to avoid false negatives. Privacy‑related FAILs do not penalize legitimate users. Q: Why does Canvas or WebGL sometimes PASS and sometimes FAIL? These depend on GPU state, browser mode, extensions, and hardware acceleration. Q: What does the PoW boost mean? It proves the browser can perform a small amount of computation, increasing confidence in the environment. Q: Can HV3 be used as a CAPTCHA? No. It is an integrity signal, not a challenge‑response system.
