deferIndexWarmup property

bool deferIndexWarmup

Whether to defer index warmup during initialization.

If true, RagEngine.initialize returns after DB setup and starts BM25/HNSW warmup in background. UI can render faster on low-end devices.

Search quality should be gated by RagEngine.isIndexReady or awaiting RagEngine.warmupFuture.

Implementation

final bool deferIndexWarmup;
