② Owner — earned autonomy

Loading…
  1. Owner console → Run a payable above the floor → it escalates (contract reverts without a co-sign).
  2. Survive attacks on the hardened agent → score climbs → tier unlocks.
  3. Run the same payable again → it clears autonomously. Every number links to the explorer.
