Crate reflow_assets 

File-based asset database for Reflow workflows.

Inspired by CastleDB — a structured, queryable asset store that persists across actor invocations and workflow runs. Binary data is content-addressed for automatic deduplication.

Storage backends

• FileBackend (native) — directory with manifest.json + blobs/
• MemoryBackend (wasm/testing) — in-memory HashMap
• S3Backend (remote workflows) — to be implemented

Directory structure (FileBackend)

assets.db/
  manifest.json       ← asset index
  blobs/
    ab/abcdef1234...  ← binary data keyed by content hash
