Unreleased

Features

• ag-ui: expose complete interrupt sessions, optional atomic persistence and authoritative recovery, and provider lifetime cleanup.

Fixes

• langgraph: retain null-payload resume commands and combined message/state input for intentional retry without reusing an aborted signal.
• ag-ui: retain exact resume decisions, roll failed state back to committed boundaries, and reject stale callbacks and concurrent recovery actions.

Breaking changes

• langgraph: LangGraphClientOptions.apiKey is removed and defaultHeaders is added. The SDK client is always constructed with apiKey: null, so the adapter never attaches a deployment key and never reads one from the environment. Send a per-user session token with clientOptions.defaultHeaders for LangGraph custom auth, and keep deployment credentials on an endpoint you own.
• cockpit-telemetry: the LangSmith runtime target forwards its key as clientOptions.defaultHeaders['x-api-key'] instead of clientOptions.apiKey.
• ag-ui: native batches take precedence over compatibility events in auto mode. Select legacy-command or mastra-command explicitly for backends requiring command transport.
• ag-ui: resume requires a pending batch and each native ID exactly once; scalar responses apply only to single-entry batches. New messages, regeneration, and client-tool continuation cannot abandon an unresolved interrupt.
• ag-ui: uncertain resumes require authoritative reconciliation before retry. Durable client claims require an application-provided atomic store; backend duplicate-effect protection requires server idempotency.
