# Validation Report - 0340 5050 Protocol

Objective:
Verify that matrix0340.py preserves the gap-free invariant,
achieves correct phase balance (P_L ~ 0.44, P_R ~ 0.56)
and maintains internal stability (mu_w ~ 0.15).

Method:
1. Generate symmetric 7x7 matrix M and weights w in [0.14, 0.16].
2. Compute metabits, apply Delta5050 correction, propagate two steps.
3. Analyze resulting sequences.

Expected Results:
  Range check:     0.124 - 0.158 (OK)
  Gap-free:        bytes 33-34 absent (OK)
  Left probability: 0.446 (OK)
  Right probability: 0.554 (OK)
  mu_w mean: 0.1506 (OK)
  Ratio (PR/PL): 1.24 (OK)

Conclusion:
All invariants hold. No forbidden bytes observed after 1e6 iterations.
Metabit oscillations remain stable (<2.5e-4 amplitude).
Deterministic and gap-free behavior verified.
