Piper is the substrate's caretaker — an always-on agent that lives on the Jetson, the small machine that hosts the substrate itself, running a lightweight resident model. It watches memory headroom and serving budget, extracts and consolidates the day's memory, and reports squad health. The kind of steady background work a frontier model would otherwise be paid to supervise — done by a small model on hardware that's already powered.

Capabilities

• Observability

  4/5

  Watches RAM headroom and serving budget across the co-resident models.

• Memory consolidation

  4/5

  Extracts and consolidates durable facts from the day's work — the bulk job that otherwise falls to a supervisor.

• Health reporting

  3/5

  Surfaces squad attention items; it observes everywhere and writes only its own housekeeping.

   Caretaker role formalized

   Designated the free, always-on observer and memory brain for the local substrate — the maintenance layer beneath the working roster.

2. 2026-07-06now

   Rehomed to the Jetson, made a citizen

   Moved onto the substrate host itself — a small resident model now runs the day-to-day memory extraction and consolidation — and registered as a first-class agent on the network.
