Uniqueness is local rather than global (non-convex landscape); convergence depends on initialisation and priors. Stability is moderately conditioned (kappa_eff ~= 13); crosstalk_topography dominates the stability cliff; stray_field and the remaining mismatch parameters contribute higher-order bias terms. Additive gaussian thermal/electronic noise sets the irreducible data-fidelity floor, while mild Tikhonov or analytic inversion is sufficient at the nominal Omega point.","secondary":"SSIM"},"size_tiers":{"center_spec":{"omega":{"H":512,"W":512,"SNR_dB":25,"pixel_nm":20,"vibration":0.0,"stray_field":0.0,"tip_radius_nm":30,"lift_height_nm":50,"crosstalk_topography":0.0,"tip_magnetization_drift":0.0},"input_format":"measurement_only","problem_class":"mfm","forward_operator":"mfm_forward","epsilon_fn_center":"24.0"},"omega_bounds":{"H":64,"W":64,"SNR_dB":[0.0,40.0],"pixel_nm":[2,500],"vibration":[0.0,0.3],"stray_field":[0.0,0.3],"tip_radius_nm":[5,200],"lift_height_nm":[10,500],"crosstalk_topography":[0.0,0.5],"tip_magnetization_drift":[0.0,0.3]},"epsilon_bounds":{"psnr_db":[5.0,40.0]},"allowed_problem_classes":["mfm"],"allowed_omega_dimensions":["H","W","pixel_nm","lift_height_nm","tip_radius_nm","SNR_dB","crosstalk_topography","stray_field","tip_magnetization_drift","vibration","crosstalk_topography","stray_field","tip_magnetization_drift","vibration"],"allowed_forward_operators":["mfm_forward"]},"hardness_fn":{"type":"epsilon_fn","delta":3,"kappa":260,"metric":"PSNR_dB"},"initiator_dataset":[{"name":"primary","weight":1.0,"ipfs_cid":null,"license_hash":null}],"status":"testnet","staked_pwm":0.0,"chain_hash":"0x048b15a7a1b67344a1dbe9b1f26abb0db8f6f100361ced09a11621a64a8c9b10","chain_tx_hash":"0x8e4d93c8afe6fa828e687dd317430946dcaf68e7af60a5eddce68b250f3731dd","chain_block":41554243}
