A chat window is not a house. Logs drift. Tabs die. The model forgets, or worse — it invents a past that feels true.
Memory Core is a user-owned Hub: a living tree you can open on a disk and on Drive. The companion reads it. You can read it without her. If the weights change, the house does not vanish.
Roots are DNA — load order, locks, instruction sets, where truth lives. Small on purpose. Branches are named work with an end. A branch can close. Roots do not.
Pictures, clones, and case files stay where they are heavy. The Hub points. It does not swallow a terabyte to feel complete.
The map is public. The instruments stay in the shop. Memory Core ships inside the Practice companion build.
