+### IX. CMAB & Async Decide
+
+The SDK supports Contextual Multi-Armed Bandit (CMAB) decisions.
+
+- `CmabConfig` data object (in `lib/src/data_objects/`) carries CMAB
+  configuration in decide responses.
+- `decideAsync`, `decideForKeysAsync`, and `decideAllAsync` provide
+  non-blocking decide calls that support CMAB lookups requiring
+  network round-trips.
+- Three CMAB-specific decide options MUST be supported:
+  `ignoreCmabCache`, `resetCmabCache`, `invalidateUserCmabCache`.
+- Async decide methods MUST have dispatch cases on both iOS and
+  Android native layers alongside their synchronous counterparts.
+- CMAB constants MUST be synchronised across Dart, Swift, and Java
+  constant files.
+
+### X. ODP Integration
+
+The SDK integrates with Optimizely Data Platform (ODP) for audience
+segmentation and event tracking.
+
+- **Segments**: `fetchQualifiedSegments`, `getQualifiedSegments`,
+  `setQualifiedSegments`, and `isQualifiedFor` manage user segment
+  membership. Segment fetch options control caching behaviour.
+- **Events**: `sendOdpEvent` dispatches custom events to ODP.
+- **VUID**: `getVuid()` returns the Visitor UUID. Enabled via
+  `enableVuid` in `SDKSettings`.
+- **Configuration**: `SDKSettings` exposes ODP tuning fields:
+  `segmentsCacheSize`, `segmentsCacheTimeoutInSecs`, `disableOdp`.
+- All ODP features MUST follow the same cross-platform parity
+  requirements as other SDK features (Principle III).
+
+### XI. Event Batching Configuration
+
+The SDK supports configurable event batching via `EventOptions`:
+
+- `batchSize` — number of events per batch.
+- `timeInterval` — flush interval in milliseconds.
+- `maxQueueSize` — maximum queued events before forced flush.
+
+Event batching settings are passed during SDK initialisation and
+forwarded to the native SDKs. Changes to event batching MUST be
+tested on both platforms.
+
+### XII. Logger Bridge Architecture
+
+The SDK uses a dual-channel architecture for logging:
+
+- **Main channel** (`optimizely_flutter_sdk`) — all API operations.
+- **Logger channel** (`optimizely_flutter_sdk_logger`) — native → Dart
+  log forwarding.
+
+Dart layer:
+- `OptimizelyLogger` abstract class defines the logging interface.
+- `DefaultOptimizelyLogger` provides the default implementation.
+- `LoggerBridge` listens on the logger channel and forwards native
+  log messages to the Dart logger.
+
+Native layer:
+- **iOS**: `OptimizelyFlutterLogger.swift` dispatches log calls to
+  the main thread via `DispatchQueue.main.async`.
+- **Android**: `FlutterLogbackAppender` uses logback integration and
+  dispatches via `mainThreadHandler.post()`.
+
+Custom loggers are configured during SDK initialisation via the
+`logger` parameter.
