+TQPE — Trignumental Quantum Phase Estimation
+=============================================
+A real, runnable 5-phase pipeline that:
+  1. Validates circuit descriptions using the TRIGNUM SubtractiveFilter
+  2. Runs actual QPE via numpy-based quantum simulation (no Qiskit needed)
+  3. Integrates results against known empirical data (epistemic integration)
+  4. Implements the Human Sovereignty gate (T-CHIP GOLD)
+  5. Commits an immutable epistemic trail
+
+Case studies:
+  • H₂ molecule ground state (E₀ ≈ −1.137 Ha) — real physics
+  • LiH molecule ground state (E₀ ≈ −7.882 Ha) — real physics
