Pair two devices once, then move several files and small text objects in either direction for fifteen minutes. Every file stays local until you press send, every receive is SHA-256 verified, and the signaling server never becomes a payload inbox.

Both devices can add text and files after the encrypted DataChannel is connected.
TRAY keeps one temporary encrypted peer route open for up to fifteen minutes so both devices can move several deliberate objects without becoming a permanent sync service.
File Intelligence computes the full SHA-256 and local SECRET/PII signals before transfer. Attention findings require explicit sender review.
Each file announces bounded metadata first. The receiver replies READY before binary chunks begin, preventing blind transfer into an unavailable tab.
Received objects live only in the current tab until download, HANDOFF, clear or close. BEAM signaling sees temporary SDP/ICE metadata, not file chunks or text content.
BEAM AS A DEVICE FABRIC
A temporary shelf between your devices.
BEAM handles deliberate single-file transfer. CLIP handles the tiny text/link moment. TRAY fills the space between them: a short-lived two-device working surface for a handful of files and notes, with explicit actions and no invisible background synchronization.
