"""
src/validator.py
Scientific Claim Validator & Empirical Consistency Auditor for Q-TensorFormer.

Enforces empirical integrity across all research outputs:
  1. Validates classification of every reported metric:
      MEASURED: Obtained directly from hardware timing/profiling.
      ESTIMATED: Computed using explicit, calibrated models.
      SIMULATED: Run on classical quantum statevector simulator.
      PROJECTED: Theoretical analytical scale-up calculation.
  2. Flags and rejects:
      - Unsupported "quantum advantage" claims without real QPU hardware execution.
      - Latency claims derived solely from FLOP counts.
      - "Zero runtime overhead" or "zero overhead" claims (slicing overhead ~20-50 us is empirically verified).
      - Unproven asymptotic guarantees (e.g. "asymptotic convergence guaranteed").
      - Fabricated benchmark percentages.
  3. Audits output artifact completeness:
      Verifies that all 13 core JSON result files and 14 publication figure PNGs exist.
