Noisy Intermediate-Scale Quantum (NISQ) devices suffer from calibration drift—slow, coherent phase errors accumulating between active corrections. We present EEDT (Entanglement-Enhanced Dynamical Tracking), a measurement-gated quantum error correction protocol utilizing noisy measurements to dictate intervention timing. Initial Lindblad simulations yielded a counterintuitive 339% deviation from theoretical bounds, which we identify as the Golden Eye collapse in low-noise regimes (σ_ro < 3%). This motivates a bifurcated theoretical model incorporating Golden Eye Occupancy (high-σ) and noise-floor saturation (low-σ) regimes, achieving 78% prediction accuracy improvement over prior models, with the critical threshold σ_c ≈ 2% analytically derived. New in v8: We report the first statistically significant real-hardware demonstration on three IBM Heron devices (ibm_fez, ibm_torino, ibm_marrakesh). After systematic qubit selection (ε_01 = 1.18%) and direct ZZ Ramsey measurement (ν_ZZ = 0.13 kHz), the stroboscopic CDQEM protocol achieves a correction gain of +0.112 at N_meas = 8 with 2.7σ significance on ibm_marrakesh, confirming the MCM post-selection effect predicted by the stroboscopic convergence theorem. All code, data, and IBM Quantum job IDs are publicly available.
