 Sentry uses a **transactional outbox pattern** for eventually consistent operations. When a model changes, an outbox row is written inside the same database transaction. After the transaction commits, the outbox is drained — firing a signal that triggers side effects such as RPC calls, tombstone propagation, or audit logging.
 
-The most common use case is **cross-silo data replication**: a model saved in the Region silo produces a `RegionOutbox` that, when processed, replicates data to the Control silo (or vice versa via `ControlOutbox`). But the pattern is general — outboxes work for any operation that should happen reliably after a transaction commits, even within a single silo.
+The most common use case is **cross-silo data replication**: a model saved in the Cell silo produces a `CellOutbox` that, when processed, replicates data to the Control silo (or vice versa via `ControlOutbox`). But the pattern is general — outboxes work for any operation that should happen reliably after a transaction commits, even within a single silo.
 
 There are two outbox types corresponding to the two directions of flow:
 
-- **`RegionOutbox`** — written in a Cell silo, processed in the Cell silo to push data toward Control (via RPC calls in signal receivers).
+- **`CellOutbox`** — written in a Cell silo, processed in the Cell silo to push data toward Control (via RPC calls in signal receivers).
 - **`ControlOutbox`** — written in the Control silo, processed in the Control silo to push data toward one or more Cell silos. Each `ControlOutbox` row targets a specific `cell_name`.
