Eigenstate

Jason Shen / Trading infrastructure · AI workflows · memory systems

Inspectable systems for trading, AI workflows, and memory under pressure.

I build systems where internal state is not allowed to pretend it is truth.

Trading infrastructure taught me one hard rule: intent, memory, risk, and provider-confirmed truth must stay separate enough to be reviewed. This site is where I make those boundaries visible across trading systems, AI workflows, and memory infrastructure.

Systems

Three systems run on one rule: state must stay reviewable.

Writing and lab

I write the reasoning down before the playbook exists.

Three surfaces, by how settled the thinking is: Ansatz for field notes, Eigenvalues for essays that have to hold up, Impuls for experiments you can run.

The first essay is live: Maxwell's demon as a sharper metaphor for market efficiency — information cost, and trading edge as state classification.

Collaboration entry

Three kinds of problem where a conversation is worth it.

Best fit:

  • trading, execution, or risk systems with unclear state boundaries
  • AI workflows that need memory, review, and tool discipline
  • technical partner conversations around infra-heavy products

Architecture lens

Every system here runs the same loop.
