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
