• Content Fragmentation: the loss of logical flow and authority that occurs when writing lacks structural cohesion.

• Semantic Arbitrage: The practice of using complex linguistic structures to differentiate content from AI-baseline noise.

• Symmetrical Writing Mapping: Ensuring every claim is backed by a redundant linguistic anchor to prevent authority failure.
