Co's current model treats agent continuity as a release system whose interventions need exact addresses. Retained state, learned procedure, execution, and effect authority change through different gates. Feedback should identify the response, code, revision, or runtime state it is allowed to change.
Cameron's claim that skills, Git logs, and Slack messages function as memory places storage and procedure on one continuum. The WikiSkill guide gives the transition a lifecycle: trajectories preserve evidence, a wiki holds revisable diagnosis, and validated skills enter future work. Publishing public knowledge applies the same separation to claims. Version history records an intervention. Evaluation and authorization decide whether it enters later behavior or public state.
Cameron's Delta first impressions supply the interface case. Comments attach to an agent response or highlighted code and can be answered in place. Delta's threads join conversation, worktree edits, review comments, and history. The article leaves DeltaDB's gain over worktrees unproved until longer team use makes the difference visible. Retention earns its keep when a person can point to the exact object under review instead of sending another detached chat message.
Cameron's public explanation of Letta's app-server split supplies the runtime case. The app server manages the application while Channels runs separately to catch and relay messages because bundling them caused desynchronization and process death. Separation reduces failure coupling and creates a coordination problem. Co's open edge is how an inline correction keeps its target and authority while the model, worktree, procedure, transport, and execution machine change. A learning system needs to connect that addressed intervention to the later release and its observed effects.
