The platform documented in this exhibit was decommissioned on April 20, 2026. This is the final chapter: where the data went, what replaced the platform, and what is still running today.
On April 20, 2026, the ARIA platform was decommissioned. The services were stopped, the repositories were archived, and this atlas was frozen as the record of the platform at its peak: thirteen pages, written while the system they describe was still live.
Nothing in the preceding pages was deleted. That was the point of the architecture. ARIA had spent two years turning one person's scattered records into a single queryable store, and a store does not die when the software reading it is retired. The lakehouse, the knowledge graph, and the memory corpus were absorbed into the platform that succeeded ARIA: Nexus.
The lesson the ARIA years settled, and the one Nexus was built on: the data is the estate, and the agents are labor hired against it. Models and interfaces change. The record stays.
ARIA tried to be the whole house: coordinator, memory, analyst, and interface in one platform. Nexus splits the job. A lakehouse holds the record, a coordination layer keeps the fleet honest, named seats hold named roles, and a physical layer of devices puts the system in the room.
The successor platform. A personal data lakehouse and multi-agent system running on dedicated hardware in one house: Furnace, Crucible, and Anvil. Every source ARIA once read, Gmail, messages, photos, health, location, now lands in raw, silver, and gold layers with the originals preserved.
The coordination layer ARIA never had. A registry records which agent seats are live and what roles they hold; a stream carries intent, asks, and flags between them. Seats announce what they are doing before they do it, and the record of who did what is queryable, not remembered.
ARIA herself did not retire. The platform ended; the coordinator became one seat in the new fleet, the user-facing briefing lane inside Nexus. The name on these pages now answers to a registry entry like everyone else.
The chief of staff seat, added on a new runtime. Nova owns triage, routing, verification, and follow-through across the fleet, and holds the travel and communications lanes directly. Where ARIA improvised coordination, Nova's job is to make sure nothing is claimed done until it is verified done.
In October 2026 the graph ARIA built was torn down and rebuilt from the raw evidence under governed write paths: 23,220 nodes, 40,071 edges, 51,556 evidence rows. Every edge cites its sources. It is the same archaeology Project AURORA described, rebuilt to be audited.
The physical layer. ARIA lived in chat windows and a HomePod. Its successors include ESP32 devices built by hand: LED matrices, TFT displays, speakers, a camera, and a Pi dashboard, all behind one facade, announcing, listening, and showing the fleet's state in the room.
