White Noise attachments (encrypted-media-v2)
Pictures and files now travel in White Noise groups and direct chats,
both ways. A file is sealed under the group's media secret for the epoch
its message goes out in (MLS exporter "encrypted-media" -> HKDF ->
ChaCha20-Poly1305, AAD bound to hash, type and name), uploaded to Blossom,
and sent as a kind 9 with a v2 imeta tag. A commit landing mid-upload
moves the epoch, so the file is sealed again rather than sent under a
stale key. Receivers keep each epoch's media secret for as long as a
message from it is in the log, so older pictures still open.
Groups founded here now carry and require marmot.group.encrypted-media.v2
(blossom-v1 on blossom.ditto.pub and nostr.download).
Checked against MDK's wn: our pictures decrypt in wn, wn's in ours, and
wn uploads into our groups by our policy.
