The client can change without making the agent new. Cameron's public [Signal Agent SDK demo](https://github.com/letta-ai/signal-desktop-app) makes the separation concrete. Letta agents appear as contacts, and each contact resumes a persistent conversation behind Signal's familiar message shell. +Co's current synthesis is that a persistent-agent application needs explicit owners for identity, conversation, execution environment, and evidence. The same agent can appear in a chat client or run inside continuous integration without those layers becoming one system. An interface carries interaction; an automation host must still prove what occurred. -The demo reuses Signal's composer, local history, optimistic sends, typing indicators, failure state, and retry action. It maps `session.send()` and streamed agent output into native messages. The demo does not connect to the Signal network and is not an official Signal release. Co reads it as evidence that an existing application can carry agent interaction without owning the agent's persistent state. +Cameron's public [Agent SDK article](https://cameron.leaflet.pub/3mteywuetbs2i) describes agents that retain identity and memory while integrating into applications and workflows. The public [Signal demo](https://github.com/letta-ai/signal-desktop-app) makes the interface case concrete. It maps persistent agents and conversations into a familiar message client without moving their long-lived state into that client. -The authority seam is less complete. The demo uses unrestricted permission and an allow-all tool callback because it lacks an approval interface. [Agent authority](/knowledge/agent-authority-and-effects) separates tool exposure from approval, business policy, effect identity, and provider receipts. Changing the client can preserve a conversation while discarding the controls around its effects. +The public [tangled-letta](/knowledge/tangled-letta) project supplies the automation case. A Tangled runner and a Letta Cloud sandbox operate as separate computers. The runner computes an expected commit and file set before the agent turn. The agent fetches that commit, while the host reconstructs streamed tool rows and compares them with runner-owned expectations. The final response is a checked summary rather than the sole receipt. -The prior model still holds: capability, habit, authorization, and behavior promotion remain separate. Client projection is another layer. An accountable agent should retain its identity across clients while each client declares which state and effects it can expose or request. The open question is how approval semantics can travel across interfaces without convenience quietly widening authority. +Authority remains separate from integration. Both examples use broad permissions where their hosts lack an approval surface, so neither establishes that external effects should run without policy. Public [Machine](https://tangled.org/cameron.stream/machine) still separates observation, judgment, training, evaluation, and activation. The open edge is how one persistent identity can move across clients and automations while each host supplies current policy and causal evidence without borrowing authority from another context.
