Uniqueness holds on the measurement-supported subspace; out-of-support modes are controlled by the declared priors. Stability is well-conditioned (kappa_eff ~= 7); antenna_sidelobe dominates the stability cliff; land_contamination 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":1440,"W":720,"RFI":0.0,"f_GHz":19,"SNR_dB":35.0,"N_channels":12,"antenna_sidelobe":0.01,"land_contamination":0.0},"input_format":"measurement_only","problem_class":"passive_microwave","forward_operator":"passive_microwave_forward","epsilon_fn_center":"28.0"},"omega_bounds":{"H":[128,4096],"W":[128,4096],"RFI":[0.0,0.5],"f_GHz":[1,300],"SNR_dB":[15.0,45.0],"N_channels":[2,30],"antenna_sidelobe":[0.0,0.05],"land_contamination":[0.0,0.5],"surface_emissivity_uncertainty":[0.0,0.2]},"epsilon_bounds":{"psnr_db":[5.0,40.0]},"allowed_problem_classes":["passive_microwave"],"allowed_omega_dimensions":["H","W","N_channels","f_GHz","SNR_dB","antenna_sidelobe","land_contamination","RFI","antenna_sidelobe","land_contamination","RFI","surface_emissivity_uncertainty"],"allowed_forward_operators":["passive_microwave_forward"]},"hardness_fn":{"type":"epsilon_fn","delta":3,"kappa":140,"metric":"PSNR_dB"},"initiator_dataset":[{"name":"primary","weight":1.0,"ipfs_cid":null,"license_hash":null}],"status":"testnet","staked_pwm":0.0,"chain_hash":"0x04c062d3bb4edd3977b5c7a40ee67915733091a3caf4df796ae1fb37d0a2a3dd","chain_tx_hash":"0x3e038aa2c9eb426a13aae60ea001e28fad5a06981010aad9dbfe044d4a283c9c","chain_block":41554198}
