Large files

Most handoffs are small (notes, excerpts, short docs) and travel as inline encrypted envelopes.

When blobs kick in

Large artifacts — codebase archives, video, big binaries — use an encrypted blob path. The envelope carries a reference and wrapped keys; object storage never sees plaintext.

Product expectations

Everyday paste-replacement stays inline.
Bigger shares are for plans that include large encrypted storage.
Agents shouldn’t push you to Drive/Dropbox for mutande handoffs; use the blob path when the app offers it.

See encryption for how seals and wraps work.
