In UTS, At Sign functions as a symbolic compression object: it helps route meaning through attention, memory, boundary, identity, action, or restoration depending on context.

3. Coherent Use

At Sign is coherent when its symbolic meaning remains auditable, scope-bound, and connected to real system behavior rather than performance alone.

4. Inversion Risk

At Sign becomes incoherent when the symbol replaces the meaning it was meant to carry, hides unresolved debt, creates false authority, or binds identity without repair capacity.

5. Restoration Use

At Sign can support restoration when it marks memory, boundary, closure, recommitment, or transition while remaining connected to material repair.

6. Canon Anchor

A symbol is coherent when its compressed meaning preserves boundary, auditability, compatibility, restoration, and identity integrity across time.
