Technical forensic specification explaining how BotRefund analyzes browser environments and network invariants to distinguish novel retail browsers from server-side automation.
Human neuromuscular motor coordination produces continuous chaotic micro-tremors, non-zero curvature jerk, and variable velocity arcs. Interaction is governed by cognitive reading pauses (80ms–150ms per keystroke; 2,000ms–8,000ms form dwell times) and natural visual scanning.
Automated scraping rings route clicks through commercial datacenter servers or residential proxy tunnels. Tunnel encapsulation (WireGuard/SOCKS5) clamps TCP SYN MSS to <= 1420 bytes, leaks residential IPs via WebRTC, or routes DNS queries through discordant overseas resolvers.
Instant Form Injection & Automated Submission Detected: The client executed a form submission exhibiting zero-interaction or instant headless injection patterns (submission < 800ms post-load, zero input keystrokes/autofill, or untrusted programmatic event dispatch). Legitimate human consumers require cognitive reading and physical input dwell time (typically 2,000–8,000ms) to inspect and populate form inputs. Instant submissions with pre-populated values indicate credential stuffing, lead spam bots, or automated checkout scripts executing direct DOM property injection.
Ad Platform Fraud Classification: Under Google Ads Invalid Traffic guidelines (Automated Click Activity) and Meta Advertising Integrity standards, sessions exhibiting Instant Form Injection violate fundamental consumer hardware invariants. They fail deterministic silicon rasterization, protocol compliance, or neuromuscular biometrics.
Why This Proves Non-Human Origin: Genuine consumer browsers on retail operating systems execute this API natively with verified hardware backing. Server software (headless cloud containers, unpatched automation harnesses, and proxy tunnels) cannot replicate this execution environment without incurring prohibitive server hardware costs.
Evidence Dossier Invariants: Each disputed click in our export packet matches an immutable server-side timestamp, landing URL, GCLID/fbclid, and observed IP address with zero client-side tamperability.
Human Baseline & Exception Scenario: None. Genuine users require cognitive reaction time and physiological input events to fill form fields.
BotRefund operates a multi-vector ensemble model. This signal adds objective forensic weight to the session dossier but never acts in isolation. Positive verdicts require corroboration across network routing, hardware silicon, and cursor kinematics to guarantee 99% precision.
This signal registers an objective, mathematically verifiable anomaly on the session ledger.
BotRefund correlates L4 packet timing, GPU silicon, and cursor jerk before finalizing risk.
