wave function
Let an agent explain the wave function, relay its role, properties and forms from quantum physics sources, describe the constructs the registry aliases name, and distinguish the wave function from the state vector abstractly, from classical waves and from probability itself, presenting interpretations with attribution.
Research draft, second pass
A second pass drafted this model: the structure a model of this thing needs, and what is known about it in the world. The line under this one says how the second half was obtained - researched against sources, or recalled without web access, in which case nothing here was read anywhere and every claim is a lead to verify. Unreviewed either way.

Purpose and description
Let an agent explain the wave function, relay its role, properties and forms from quantum physics sources, describe the constructs the registry aliases name, and distinguish the wave function from the state vector abstractly, from classical waves and from probability itself, presenting interpretations with attribution.
In quantum mechanics, a mathematical function describing the quantum state of a system, whose squared magnitude gives probability densities for measurement outcomes, evolving by the Schroedinger equation, with forms and related constructs such as one-electron wave functions or orbitals, normalisable wave functions, Coulomb wave functions for charged particle scattering, Bloch waves in crystals, tensor network representations of many-body states and the universal wave function of interpretations such as many-worlds; interpretations of the wave function remain debated.
What it is for: Describing quantum states.
It can be explain the concept; relay properties and forms; describe related constructs; distinguish interpretations with attribution.
Distinguishing features

Interpretations debated
What it looks like
Not a visible object; a mathematical function.
Physical character
Schroedinger equation: 1926 year
Born rule: 1926 year - probability interpretation
normalisation: integral of squared magnitude equals 1 note
How it is recognised
Function describing a quantum state
One-electron wave function, normalisable wave function, Coulomb wave function, Bloch wave, tensor network, universal wave function
State vectors are abstract; classical waves are physical oscillations; probabilities are derived via the Born rule
