1. The foundation that managed scarcity, but not yet

Isaac Asimov’s Foundation returns one last time for this arc because the desktop’s power system will eventually need the same long-term resource management. The conclusion, however, is more modest than the novel. The desktop will be designed so that dynamic power trading is possible, but the trading algorithm will not be turned on until the basic power bus is proven.

Entries 441 through 443 wondered about dynamic power trading between cells. This entry closes the arc.

2. What was decided

The desktop will be designed as power-trading-ready, not fully power-trading on first launch. This means:

  • The power bus will include per-cell switches, current limits, and metering.
  • The first operational mode will use fixed allocations and ground-commanded load shedding.
  • Dynamic trading will be added as a software upgrade after the basic power distribution is proven.
  • Priority policy, audit logging, and emergency fallback will be built from the start.

3. Why this is the right posture

Full dynamic power trading on day one would add algorithmic complexity and verification burden before the basic bus is trusted. Ignoring it entirely would force a hardware redesign later. Designing as power-trading-ready preserves optionality: the cells can share power autonomously when the operators are ready to trust them.

4. What this implies for the power architecture

The power system must be more than a shared bus with fuses. It needs:

  • Switchable paths between cells and the main bus.
  • Current and voltage sensing on each path.
  • A control protocol that can carry requests, state, and emergency commands.
  • A policy engine that can override trades to protect the bus.

5. Relationship to the network arc

The dynamic power trading arc connects to the self-reconfiguring network arc from Entries 425 through 428. Both require distributed state, policy, and fallback. The same infrastructure that lets cells negotiate routes can be extended to let them negotiate power.

6. What comes next

The next arc is the power distribution test. The power-trading decisions will feed into that test by setting requirements for per-cell switching, metering, and fault response.

7. What this changes

  • The dynamic power trading arc is closed.
  • The desktop’s power architecture will support metering, switching, and policy from the start.
  • Full autonomous power trading is deferred until the basic power distribution is proven.
  • The next cycle can proceed to testing with these requirements in mind.
