Module storage 

Central SQLite state store (PRD §10, §11).

One database for every download, in the platform’s data directory — not a sidecar .part.json next to each file. That is what makes rget list, rget resume --all and cross-run recovery possible.

Durability rules live in docs/CRASH_CONSISTENCY.md. The one that matters here: Store::commit_progress is the only way range progress becomes persistent, it is a single transaction, and the engine calls it only after an fdatasync of the destination file.
