Governed Agent Morphogenesis: Runtime Organizational Reconfiguration with Bounded Authority and Causal Continuity

Agent collectives may need to recruit specialists, transfer work, and retire participants during a mission. Such changes cross independently authoritative services and can leave material effects even when a competing proposal wins organizational commitment. We present a transition contract connecting an exact approved proposal, current owner authority, stable effect identities, accepted lineage, and explicit cleanup. A reference implementation separates successful completion from terminal supersession of a losing proposal. Reproducible PostgreSQL experiments exercise concurrent transitions, mandate expiry, lost acknowledgements, and retirement with admitted work. An adversarial admission matrix compares four controllers under identical owner enforcement; the durable workflow and Morphogenesis both reject invalid authority and preserve recoverable effects. A bounded TLA+ model checks successor uniqueness, stable effects and safe termination, with counterexamples for deliberately weakened variants. These results identify the integration obligations that make organizational reconfiguration inspectable and recoverable. Version 1.0. Reference implementation: AgentPlat 1.0.0.
