 ### Event-Driven Data Flow
 
-The contract uses a getter-less design: all state mutations emit events. These are projected off-chain into a Postgres read model, which powers all frontend queries. No on-chain reads required. In parallel, the frontend subscribes to `NewPublicationStatus` events via standalone viem WebSocket clients (Alchemy WSS), independent of wallet connection state, debouncing cache invalidations so the publications table stays in sync without polling.

-**Smart polling**: Query hooks like `usePublicationDetail` use a dynamic `refetchInterval` that polls every 5 seconds while a publication is in a pending state, and automatically stops polling once it reaches a terminal status (`PUBLISHED`, `SLASHED`, or `EARLY_SLASHED`). The `PublicationDetailsProvider` context wraps this pattern, exposing live publication data and a syncing indicator to all child components.
+**Smart polling**: Query hooks like `usePublicationDetail` use a dynamic `refetchInterval` that polls every **10 seconds** while a publication is in a pending state, and automatically stops polling once it reaches a terminal status (`PUBLISHED`, `SLASHED`, or `EARLY_SLASHED`). This complements WebSocket-driven status updates: reviewer assignment (`Agent_PickReviewers`) and per-review progress (`Agent_RecordReview`) do not emit `NewPublicationStatus`, so polling still refreshes detail data between status transitions. The `PublicationDetailsProvider` context wraps this pattern, exposing live publication data and a syncing indicator to all child components.
 
-**WebSocket cache invalidation**: The `/publications` table uses `useWatchNewPublicationStatusEvent` to subscribe to `NewPublicationStatus` on-chain events on both chains via standalone viem WebSocket clients (`eth_subscribe` over Alchemy WSS), independent of wagmi's wallet connection state. This means all visitors see real-time updates — even without a connected wallet. When events arrive, a debounced invalidation (3-second delay for CQRS eventual consistency) triggers a TanStack Query refetch, keeping the table in sync without polling or manual refresh.

 ## Key Patterns
 
-- **Smart polling** -- `refetchInterval` dynamically stops when a publication reaches a terminal status, eliminating unnecessary network requests
-- **WebSocket real-time invalidation** -- `useWatchNewPublicationStatusEvent` subscribes to `NewPublicationStatus` on-chain events via standalone viem WebSocket clients (Alchemy WSS) on both chains, independent of wallet state; rapid-fire events are debounced into a single TanStack Query cache invalidation (3-second delay for CQRS eventual consistency)
+- **Smart polling** -- `refetchInterval` (10s while non-terminal) dynamically stops when a publication reaches a terminal status, covering DB fields not tied to `NewPublicationStatus`
+- **WebSocket real-time invalidation** -- `useWatchNewPublicationStatusEvent` (via `PublicationsRealtimeProvider` in the publications layout) subscribes to `NewPublicationStatus` on-chain events via standalone viem WebSocket clients (Alchemy WSS) on both chains, independent of wallet state; rapid-fire events are debounced into TanStack Query invalidations for publications and global stats (3-second delay for CQRS eventual consistency)
 - **Optimistic updates + delayed invalidation** -- immediate UI feedback on transactions, with a 3-second delayed cache invalidation to account for Alchemy webhook -> CQRS projection latency
 - **Server-first data loading** -- RSC fetches from Neon via `@packages/cqrs`, hydrates client hooks via `initialData` for zero-loading-state initial renders
 - **`"use server"` CQRS bridge** -- all Drizzle DB queries stay server-only, exposed to client hooks through Next.js Server Actions
