Classes
Constants
- kDefaultDownloadConcurrency → const int
- Chunk download concurrency (Step 1). N chunks fetched + decrypted at once, bounded by a ChunkSemaphore; out-of-order completion is reassembled by writing each chunk at its fixed file offset.
- kSequentialDownloadChunkThreshold → const int
- Files with this many chunks or fewer keep the simple sequential path.
