Back MAF's opt-in AG-UI snapshot persistence with a DB store so the conversation survives page reloads and restarts: - ChatThreadSnapshot: one upserted row per (scope, thread_id), JSONB messages/state/interrupt (migration 794baf50635b) - PostgresSnapshotStore implements the AGUIThreadSnapshotStore protocol. It opens its own sessions (MAF saves during SSE streaming, after the request middleware has closed the ContextVar session) and sanitizes on save: camelCase toolCalls/toolCallId (the @ag-ui/client Zod schema strips snake_case, which would lose cards on replay), drop BFF ctx-* context messages, dedupe MAF's re-recorded multi-run turns, and drop orphaned tool results - Endpoint mount gains snapshot_store + a constant scope resolver (single-user app; auth already enforced by agent_auth_and_session) - DELETE /api/v1/chat/thread resets the conversation Co-Authored-By: Claude Fable 5 <noreply@anthropic.com>
