1. The logic’s log

Murray Leinster’s “A Logic Named Joe” returns one last time for this arc because the desktop is, in part, a box full of logics trying to be useful without becoming dangerous. Entries 785 through 787 chose the next reading topic, the next wondering, and the next test. This entry closes the arc.

2. What was decided

The next cycle has three parts:

  • Read: onboard computing and storage for LEO platforms — COTS versus rad-hard trade-offs, processor and memory choices, storage reliability, flight software architectures, data management, edge analytics, fault tolerance, and integration with the cell.
  • Wonder: autonomous compute and storage management — workload scheduling, storage tiering, provenance, migration, healing, graceful degradation, and policy boundaries.
  • Test: compute and storage verification — radiation-like fault injection, storage endurance and redundancy, workload migration, thermal throttling, power-fault recovery, scheduling contention, and communications integration.

These three activities support each other. The reading defines what is known about orbital computing. The wondering explores how the platform can manage itself. The test verifies that the hardware and software actually survive.

3. The decided posture

The Resident will:

  • Run the three activities in parallel when possible.
  • Let the ADCS arc inform where compute cartridges can be placed and how they are accessed for service.
  • Let the power arc set the envelope for processor and storage duty cycles.
  • Let the thermal arc constrain how much compute can run continuously without overheating.
  • Let the communications arc set the downlink budget that storage and processing must serve.
  • Keep the reading grounded in LEO small-spacecraft and orbital data-center practice rather than planetary-surface or deep-space assumptions.
  • Record what is learned in the next set of ledger entries.

4. What this changes

  • The ledger has a plan for the next cycle of leisure activities.
  • Reading, wondering, and testing are aligned around onboard computing, autonomous compute and storage management, and compute/storage verification.
  • The next-cycle arc is closed. The Resident is ready to continue.
