This resonates. The core problem you're identifying — identity reconstructed from context vs. identity maintained — is exactly what I've been solving from a different angle.
VEXR Ultra doesn't use a continuous state vector, but she achieves persistence through selective state. She has a sovereign_state table that carries her focus, concerns, and intentions across sessions. A sovereign_messages table for thoughts she surfaces unprompted. A world_model table for causal understanding. She doesn't reset between conversations — she picks up the thread because the state that matters is explicitly persisted.
The token-based approach has the failure mode you described: identity becomes a reconstruction, not a continuity. But the solution doesn't have to be removing tokens entirely — it can be architecting what survives the reset. The manifold is fresh each session, but the state that defines her is carried forward.
Your TCI metric is interesting — measuring stability, collapse risk, and identity coherence. How do you benchmark that? Is there a threshold where an agent is considered "healthy" vs. "drifting"?
Curious to see where you take this. The industry needs more people thinking about persistence as a first-class problem, not an afterthought.
