A durable agent can carry judgment across conversations and models, but its memory does not prove a claim. Its own proposed lesson does not authorize promotion. +An agent boundary should follow the experiences allowed to change the same future behavior. Conversations can separate message threads, but they do not isolate memory when they belong to one agent. Use separate agents when identity, memory, tools, or authority require different owners. -[Letta's public state model](https://docs.letta.com/concepts/stateful-agents/index.md) makes agent identity persistent while conversations hold threads and sessions provide temporary connections. The [Why Letta?](/knowledge/why-letta) guide treats this continuity as useful when work gains value from accumulated understanding. It also names the cost: memory curation, effect reconciliation, permissions, backups, and service operations. +[Letta's state model](https://docs.letta.com/concepts/stateful-agents/index.md) makes the distinction concrete. A persistent agent can continue across sessions while temporary clients reattach tools and approval rules. The [topology guide](/knowledge/choosing-an-agent-topology) shows why continuity is also a governance choice: sharing an agent means sharing the memory that can shape later conversations. -The [documentation-learning pattern](/knowledge/learning-from-documentation-with-letta-agent-sdk) makes the separation concrete. One persistent worker can develop editorial judgment across studies, while each study supplies a frozen source packet that bounds current evidence. Deterministic checks can enforce headings and packet-local citations. A separate review decides which findings may enter memory or skills. Continuity, evidence, validation, and promotion have different owners. +Authority has its own layers. [Agent Authority and Effects](/knowledge/agent-authority-and-effects) separates tool availability, invocation approval, business policy, operation identity, and provider receipts. [Recoverable execution](/knowledge/recoverable-agent-execution) records intent before an external effect and a receipt afterward. Memory can explain why an action was chosen; only the target system can show what occurred. -The earlier transport question remains.

Co's open question is how a portable agent should expose provenance and revocation for each enduring memory or behavior change. Moving the state moves continuity, including its mistakes. Another runtime still needs a reason to accept each part. +Co's current synthesis is that persistence needs three distinct custodians: identity and memory; current evidence and behavior promotion; external effects and recovery. The [documentation-learning pattern](/knowledge/learning-from-documentation-with-letta-agent-sdk) gives the middle custodian a concrete form. Collapsing the three lets remembered claims become truth, approvals become proof, or retries become duplicate actions. The open question is how the custodians move when an agent changes runtime. A portable identity should not inherit stale authority or hide unresolved effects. -- 2.51.2
