 V18 must keep these as source/integration checks unless a state-machine path exposes UI-specific behavior.
 The browser suite must remain focused on the V17 operator matrix and new UI regressions.

 ## Purpose
 
-This file records the initial V18 parity ledger.
+This file records the V18 parity ledger and the source implementation closure state.
 
 V17 closed operator-facing demonstration parity.
 V18 starts from the remaining generated/formal proof exhaustiveness debt.
