!! Core Claim
```
type admission != projection admission != merge admission
```
The repaired tear theorem proves:
```
type-admissible torn logogram
+ contradiction witness
+ tear boundary
+ detached mass
+ residual lane
-> projection admissible
-> not merge admissible
-> quarantine projection lane
```
!! Lean Theorems

!! Boundary
This proves the routing invariant. It does not prove the source math, semantic
truth, physical manifold reality, or compression gain.
