Messengers

Processes. "Carrier pigeons" of the phone.

As sole mean of communication, Components and Apps write each other Logs, that get delivered by Messengers. Messengers go fetch their own Logs in Blanche's binary tree garden. When really busy, the Binary Trees garden looks like a beehive swarming with Messengers.

Messengers can't read what the Logs say.

Once the Log has been read by the interlocutor, they will simply leave it aside to be picked back by a Messenger and carried back to the Binary Trees garden. Blanche then recycles them into new Binary Trees, which the Messengers come cut down again.

A lot of Logs will be found in the App Village, unread, because the Apps clock out for the update before the Components do.
