// Package attachments provides content-addressable file storage for SynapBus.
|
|
//
|
|
// Files are stored on the local filesystem using a two-level sharded directory
|
|
// structure based on the SHA-256 hash of the content:
|
|
//
|
|
// {data_dir}/attachments/{hash[0:2]}/{hash[2:4]}/{hash}
|
|
//
|
|
// Deduplication is automatic: identical content produces the same hash and is
|
|
// stored only once on disk, while each upload creates its own metadata row in
|
|
// SQLite. Garbage collection removes orphaned files that are no longer
|
|
// referenced by any message.
