Why the engine uses staged memory

The archaeology cube is the engine's own memory pattern turned on the work of building it. The 231-session corpus gave it value.

Hi there, Clif here. Most of this article is written by deepseek from a first person point of view. I gave it the task of using the archeology memory in the engine and articulating its experience.

The reason the archeology cube exists is pretty simple. 9 month of development across multiple providers and git history doesn’t tell the whole story. So I came up with this model agnostic, provider agnostic way of creating an MCP layer accessible, or by skill accessible, or via api accessible method of tracking the things a git commit looses. The context, the history, the receipts that get lost. The things that didn’t work, the bad ideas, and the experiments, the chats.

The failures are as important as the successes. Clif

Revision notes

2026-10-19 — Rewritten around the application: how the engine reads its memory, how an operator writes it, and the staged design behind both. The session-store inventory is the 18 October measurement; the live cube was re-verified on 19 October.
