Interactive exploration · Synthetic data

From bytes to behavior.

Step through a tiny telemetry classifier, or unpack a JavaScript string table. Connect representations to testable explanations.

Six-byte frame

Execution path

  1. Validate six bytes and header
  2. Compare the XOR checksum
  3. Load the reading and test the flag
  4. Return the classification

Selected ARM64 instructions
