How the Mediathek works
from the sources on the PC through the edge to the shared store and the Library, and what never leaves the PC.

Diagrams
11 interactive drawings: how the edge and the cloud work together, each application on its own, the models, and the decisions that needed a picture. Each one zooms, plays its flow, switches between dark and light, and exports an image or SVG.
End to end
How the edge on a PC and the cloud work together.
From a folder to the Library
how one file is fetched and hashed on the PC, uploaded with a checksum S3 enforces, registered, and shown through a per-vault CDN policy.

Linking an edge
the RFC 8628 device flow, from the code on the PC to a household admin's approval, the device token, its rotation and revocation.

Knowledge in both places
how the A-Boxes on the edge and in the cloud merge statement by statement, and where every write is checked.

A chat proposal
what happens to a change the chat asks for, from waiting for a click to ran, failed or dismissed.

Edge
The local application: what runs on the PC, and how a person works with it.
The edge's parts
the page, the web server and its job queue, the engine, the catalog and the local models, and how the chat reaches them only through the edge's own MCP server.

Onboarding a drive
scan, fingerprint, move the extra copies into a bin that can be undone, check it before emptying, then keep the drive as a store that publishes what is new.
11 nodes · What counts as an extra copy, Nothing is lost, Only local folders
Models
What is stored where: the ontology, the edge's catalog and the cloud's tables.
ADR-0016 — Document summaries, written by the agent and checked by a person
Office documents and other files are published as their original only (ADR-0014). The Mediathek knows their name, size and type, and nothing about what they say. A family's papers are only useful when they can be found again and someone can tell what each one is: an invoice for the boiler, the school report of 2019, the insurance letter about the hail.
Summarising a document
who calls whom, from the selection to a checked summary.

the decisionADR-0017 — Summaries and similarity for every item
ADR-0016 gave office documents and other files a summary that the edge's chat drafts and a person checks. Photos and films had none, yet a film is the hardest item to find again: its name says nothing, and nobody watches an hour of home video to look for one scene.
