Uniqueness is local rather than global (non-convex landscape); convergence depends on initialisation and priors. Stability is moderately conditioned (kappa_eff ~= 12); atmospheric_aerosol dominates the stability cliff; glint 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":1024,"W":1024,"GSD_m":1000,"glint":0.0,"SNR_dB":40.0,"N_bands":9,"whitecaps":0.0,"bottom_reflectance":0.0,"atmospheric_aerosol":0.1},"input_format":"measurement_only","problem_class":"ocean_color","forward_operator":"ocean_color_forward","epsilon_fn_center":"25.0"},"omega_bounds":{"H":[256,8192],"W":[256,8192],"GSD_m":[10,5000],"glint":[0.0,0.3],"SNR_dB":[15.0,45.0],"N_bands":[4,20],"whitecaps":[0.0,0.2],"bottom_reflectance":[0.0,0.5],"atmospheric_aerosol":[0.0,0.5]},"epsilon_bounds":{"psnr_db":[5.0,40.0]},"allowed_problem_classes":["ocean_color"],"allowed_omega_dimensions":["H","W","N_bands","GSD_m","SNR_dB","atmospheric_aerosol","glint","whitecaps","bottom_reflectance","atmospheric_aerosol","glint","whitecaps","bottom_reflectance"],"allowed_forward_operators":["ocean_color_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":"0x2872ae4cf04d30781ff708ce9b1274ff7628fc15626b54e5b57131ca9a037839","chain_tx_hash":"0xfe76fc657d6abac267c037d3ec50e6bdfacd2cfec84c6fd5eeb948049c0dccf2","chain_block":41554198}
