Uniqueness is local rather than global (non-convex landscape); convergence depends on initialisation and priors. Stability is moderately conditioned (kappa_eff ~= 12); tip_convolution dominates the stability cliff; thermal_drift 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":30,"pixel_nm":2,"tip_wear":0.0,"thermal_drift":0.0,"tip_radius_nm":5,"tip_convolution":0.0,"nonlinear_response":0.0},"input_format":"measurement_only","problem_class":"afm","forward_operator":"afm_forward","epsilon_fn_center":"28.0"},"omega_bounds":{"H":128,"W":128,"SNR_dB":[0.0,40.0],"pixel_nm":[0.1,100],"tip_wear":[0.0,0.5],"thermal_drift":[0.0,10],"tip_radius_nm":[1,100],"tip_convolution":[0.0,0.5],"nonlinear_response":[0.0,0.3]},"epsilon_bounds":{"psnr_db":[5.0,40.0]},"allowed_problem_classes":["afm"],"allowed_omega_dimensions":["H","W","pixel_nm","tip_radius_nm","tip_convolution","thermal_drift","tip_wear","nonlinear_response","SNR_dB","tip_convolution","thermal_drift","tip_wear","nonlinear_response"],"allowed_forward_operators":["afm_forward"]},"hardness_fn":{"type":"epsilon_fn","delta":3,"kappa":240,"metric":"PSNR_dB"},"initiator_dataset":[{"name":"primary","weight":1.0,"ipfs_cid":null,"license_hash":null}],"status":"testnet","staked_pwm":0.0,"chain_hash":"0x3fcf235db9b4136a596c788864ecece37e46c781e5310c6939d9db3260c050ca","chain_tx_hash":"0x247e631b2b7c81daaae99bcc2e4381d9ccbcc12d28717404ddbc7df44d0add58","chain_block":41554242}
