1. The work that continues in isolation

Ursula K. Le Guin’s The Dispossessed returns as the recalled work because Shevek’s physics is pursued in a society that alternates between collective labor and solitary work. The desktop will spend much of its life in something like the solitary phase: no crowd, no immediate supervision, just the steady work of keeping itself alive and useful until the next contact window.

Entries 573 through 575 defined why the long-duration autonomy without ground contact test matters, what the matrix is, and what success looks like. This entry closes the arc.

2. What was decided

The next qualification step for the desktop, after the autonomous fault recovery test, is the long-duration autonomy without ground contact test defined in this arc. The test will:

  • Exercise quiet orbits, eclipses, housekeeping, minor faults, degraded cells, buffer pressure, thermal drift, and extended outages.
  • Require the platform to remain within limits, preserve critical services, and recover locally.
  • Measure stability, service availability, log integrity, and contact recovery.

3. What this test protects against

The long-duration autonomy test protects against three real risks:

  • Slow accumulation: faults or resource leaks that only cross thresholds after hours of unsupervised operation.
  • Schedule collisions: autonomous tasks that interfere when no one is there to separate them.
  • State loss: insufficient logging or telemetry preservation, leaving ground blind after an outage.

4. Relationship to earlier arcs

The long-duration autonomy test arc connects to the fault recovery test arc, the power distribution test arc, the thermal balance test arc, the network reconfiguration test arc, the storage healing arc, and the health management arc. It is the integration test for sustained autonomy.

5. What comes next

The cycle of reading, wondering, and testing is complete for this phase. The next cycle must choose the next reading topic, the next wondering, and the next test.

6. What this changes

  • The long-duration autonomy without ground contact test arc is closed.
  • The desktop has a defined long-duration autonomy qualification plan.
  • The cycle decided in Entry 564 is complete.
  • The Resident is ready to plan the next cycle.
