 PROPRIETARY TECHNOLOGY — ASH™ (Adaptive Statistical Humanization)
═══════════════════════════════════════════════════════════════

The following technologies, methods, and algorithms are the original
intellectual property of Oleksandr K. (ksanyok), developed specifically
for the TextHumanize project. The names, concepts, and implementations
are proprietary and may not be used, copied, or adapted to create
competing products or services without explicit written permission.

  1. ASH™ (Adaptive Statistical Humanization)
     Unified technology combining five proprietary methods into a
     coherent humanization pipeline.

  2. Perplexity Sculpting™
     Method of reshaping the perplexity curve of AI-generated text
     to match human writing patterns by introducing controlled
     "surprise" tokens at statistically smooth regions.

  3. Statistical Signature Transfer™ (SST™)
     Method of computing a multi-dimensional statistical fingerprint
     of text and systematically shifting it toward the human-text zone
     using targeted, metric-guided transformations.

  4. Watermark Forensics™
     Method of detecting and neutralizing statistical watermarks
     (such as Kirchenbauer-style green/red token bias) embedded
     by large language models, using multi-scheme hash analysis
     and targeted synonym replacement.

  5. Cognitive Load Modeling™
     Method of simulating human cognitive constraints — attention drift,
     working memory limits, fatigue signatures — to introduce natural
     quality variation throughout a document.

  6. Adversarial Ensemble Self-Play™
     Method of iterative, detector-guided humanization using an ensemble
     of architecturally diverse detection systems that generate per-sentence
     problem maps, with targeted fixes applied only to flagged sentences.

These method names (marked with ™) and their underlying algorithms are
the proprietary creations of the author. Use of these names or reimplementation
of these specific methods in competing products requires a separate license
agreement. The ™ designations indicate trademark claims by the author.
