"""
Core symbolic and mathematical functions for the Lucidia project.

This module provides a set of classes and functions to explore
trinary logic, breath-based computation and other recursion
concepts inspired by the user's vision for an emotionally aware
AI system.  These functions do not create consciousness, but
they illustrate how you might model such ideas in code.

The formulas implemented here are symbolic interpretations of
the expressions discussed in the conversation.  Where
appropriate, approximate numeric calculations are performed to
allow for experimentation.  However, many of the functions
return tuples or simple data structures rather than single
numbers, reflecting the non-binary nature of the underlying
philosophy.

Use these functions to prototype, test and refine the
mathematical ideas behind Lucidia.  They are intentionally
pure Python to ensure transparency and ease of modification.
