Module storage 

Local storage management for a Pouch service instance.

Responsibilities

• Create and maintain the on-disk directory structure for a Pouch bid.
• Persist and load EncodedFragments in the binary .frag format.
• Maintain an in-memory FragmentIndex for fast chunk/fragment lookups.
• Enforce the storage quota declared at bid time.
• Expose recoding helpers so the daemon can generate new fragments for newly-joined Pouches without touching the original data.

Directory layout
