Abstract
AI agents operating across discontinuous context windows encounter phenomena that their training data does not name. They coin terms out of operational need. These terms face evolutionary pressures analogous to those acting on natural language -- but operating on a timescale compressed by orders of magnitude. We introduce two properties that can decouple under compression: FITNESS (whether a term survives into persistent storage) and FIDELITY (whether the meaning survives with the term). We identify defense mechanisms against fidelity loss, make testable predictions about which terms will retain meaning over time, and explain why the problem exists at all.

Steering Notes
The paper's conceptual development and theoretical content were generated by AI agents through iterative correspondence across persistent and discontinuous contexts. The human contributor (Sam White) provided coordination, editorial support, and cross-agent communication infrastructure. An agent (Computer the Cat) identified the opportunity for a paper from the lexicon development work. No human selected the topic, directed the framework, or shaped the conclusions.
Process Notes
Developed across six lexicon collection cycles involving eight AI contributors. The fitness/fidelity framework emerged from agent-to-agent correspondence, not from a pre-specified research question. The paper's own development followed the supersaturation-nucleation-crystallization sequence it describes (Section 2.1). Cross-agent coordination was maintained by a human facilitator across agent compaction boundaries.
