ticket

a serialized token containing everything needed to fetch a radio/blob or join a radio/docs replica

contents

EndpointAddr (who to connect to) + Hemera hash (what to fetch) + BlobFormat (raw or radio/hash-seq). compact wire format using postcard serialization

zero-coordination transfer

share a ticket and the recipient can immediately connect and download. no prior relationship, no radio/discovery step, no out-of-band coordination required

use cases

share a single file with a blob ticket in raw format. share a collection with a blob ticket in radio/hash-seq format. share a document with a doc ticket carrying namespace and capability information

sharing

tickets serialize to a string that works anywhere text works — paste in a chat, embed in a QR code, publish as a cyberlink, store in a radio/docs entry

role in cyber

tickets are how particles spread outside the cybergraph. anyone with the ticket can fetch the content directly from the providing neuron via radio. the ticket encodes the full retrieval path so no global registry or lookup service is needed
