+#+TITLE: SKILL: Formal Verification Gate (Universal Literate Note)
+#+ID: skill-formal-verification
+#+STARTUP: content
+#+FILETAGS: :security:logic:formal-methods:psf:
+
+* Overview
+The **Formal Verification Gate** replaces heuristic whitelisting with symbolic logic proofs. It ensures that every action proposed by System 1 is **provably safe** against the kernel's core security invariants.
+
+* Phase A: Demand (PRD)
+:PROPERTIES:
+:STATUS: FROZEN
+:END:
+
+** 1. Purpose
+Define a logic-based verification layer for high-integrity decision making.
+
+** 2. User Needs
+- **Invariants:** Define core security properties (e.g., "No unauthenticated network I/O").
+- **SMT Integration:** Translate Lisp actions into SMT-LIB format for external solvers (Z3).
+- **Proof of Safety:** Deny any action that cannot be proven safe.
+
+* Phase D: Build (Implementation)
+
+** Invariants Registry
