By probing the inner few hundred parsecs, this spatially resolved approach reveals exactly how gas-phase metallicity fluctuates within the active nucleus. Specifically, we demonstrate that these local Seyferts exhibit positive (inverted) metallicity radial profiles over extended periods due to seamless gas accretion histories. Furthermore, our spatially resolved data establishes a clear anti-correlation between the central gas-phase metallicity and the AGN&rsquo;s Eddington ratio.</p> <h3 id="interactive-ifu-radial-profile-simulator">Interactive IFU Radial Profile Simulator</h3> <p><em>Compare the steep negative gradient of a normal star-forming control galaxy to the flattened and inverted gradients caused by AGN gas mixing.</em></p> <iframe src="https://mrkrmh.github.io/simulations/Spatial_Simulator.html" width="100%" height="550px" style="border:none; border-radius: 12px;"></iframe>
