Comms
One bundle, every door. Paste whatever you are carrying — a jar card, a field-guide leaf, a signed page, a few words — and the ladder names it and offers the cheapest rung that fits: a code on paper, a river of light, or a paste by hand. No server picks the road; the road is the one the two of you can walk.
What you're carrying
What it is
One paper code — hold it up, or fold it into someone's pocket.
The stream carries more than a single code will hold.
The ladder
The rung is whatever fits. A small bundle rides one code and a steady hand. A longer one rides the river of frames. Everything can be pasted. When the sound handshake is built it will be the rung for a camera-blocked room; the live hello stays a call, not a delivery. The ladder is a rule for choosing, never a chain of command.
It never pretends to know more than the scheme in front of it. The pass
reads the bundle's own name — hand://, a cs-place.v1 leaf, a
.escrow.json bundle — and names what the next door should do with it.
Unrecognized words are just words, and they travel just as well.
The rule lives at communityservices.cc/COMMS.md; the queue is issue #113.
