Apps
What ships today, what is internal, what is research.
Four applications, one parent. Each application is sealed under its own surface canon and lives at its own subdomain. The cards below are rows in a Lacuna-themed index; the linked surfaces wear their own visual register.
| Application | Description | Status |
|---|---|---|
| Sakura | The Curator. A collection partner that helps an operator understand a piece and, if they want, list it for sale. Etsy and eBay. One surface, two outlets. Operates under its own DID; visually distinct from the parent on purpose. | shipping v2.5 |
| Apollo | An object encyclopedia. A public reading surface over Atlas and the opted-in slice of Engram. Anyone can browse the work; a visitor considering a piece can see the reference behind the attribution. | deferred v2.6 |
| Atlas | The shared reference graph. Makers, periods, hallmarks, reference specimens. Read by Apollo; auto-linked from Engram entries. Public reference data only — no operator content unless explicitly contributed. | internal |
| Loam | The world-building cache between live-web reads and the language models. Four layers: raw page bytes, normalized diffs, cached Q&A nodes, and an emergent topic graph. Cohort-anonymized at the gateway. Memgraph in-memory in the default deployment. | research |
Substrates beneath
Six substrates plus a peer vision service. Each owns one job; they share a canonical type system; they stay out of the operator's sight. Not products on their own — the floor every application stands on.
| Substrate | Role | Locus |
|---|---|---|
| Sakura | The operator-side companion. Personality, voice, local intelligence. | device |
| Cortex | Rust graph engine. The operator's pieces, conversation, embeddings, corrections. | device (L0) |
| Engram | Per-customer cloud projection of Cortex. Math and metadata only — never conversation or raw blobs. | cloud (L1) |
| Atlas | Shared global reference graph. Makers, periods, hallmarks. Public reference only. | cloud (L2) |
| Apollo | Public face. Reads Atlas and the opted-in slice of Engram. | cloud |
| Loam | World-building cache between live-web reads and the language models. Cohort-anonymized at the gateway. | cloud (L1.5) |
| Vision LLM | Peer service. Embedding model in the browser today; fine-tuned classifier tomorrow. Every substrate may call it. | peer |
