## Problem 104 — rank:78

**Title:** Memory engrams

**Added binding assumptions (LaTeX):**

```latex
Require baseline recall above $q$ by a fixed margin and a genuine intervention decrement; otherwise the empty target can satisfy the silencing criterion. Define inclusion-minimality by failure of the full criterion for every proper subset, not minimum cardinality. The activation target needs a separate recovery threshold and matched inactive-control contrast. Preserve locomotor, sensory and unrelated-memory controls in both tests.
