Uniqueness holds on the measurement-supported subspace; out-of-support modes are controlled by the declared priors. Stability is well-conditioned (kappa_eff ~= 5); atmospheric_correction_error dominates the stability cliff; bidirectional_reflectance 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":10,"SNR_dB":40.0,"N_bands":13,"cloud_contamination":0.0,"atmospheric_correction_error":0.0},"input_format":"measurement_only","problem_class":"multispectral","forward_operator":"multispectral_forward","epsilon_fn_center":"33.0"},"omega_bounds":{"H":[256,16384],"W":[256,16384],"GSD_m":[0.3,1000],"SNR_dB":[15.0,45.0],"N_bands":[3,20],"cloud_contamination":[0.0,0.5],"bidirectional_reflectance":[0.0,0.2],"atmospheric_correction_error":[0.0,0.2]},"epsilon_bounds":{"psnr_db":[5.0,40.0]},"allowed_problem_classes":["multispectral"],"allowed_omega_dimensions":["H","W","N_bands","GSD_m","SNR_dB","atmospheric_correction_error","cloud_contamination","atmospheric_correction_error","bidirectional_reflectance","cloud_contamination"],"allowed_forward_operators":["multispectral_forward"]},"hardness_fn":{"type":"epsilon_fn","delta":1,"kappa":100,"metric":"PSNR_dB"},"initiator_dataset":[{"name":"primary","weight":1.0,"ipfs_cid":null,"license_hash":null}],"status":"testnet","staked_pwm":0.0,"chain_hash":"0x38ac8ba6ad8e2210be640789f2161540b31e1a4179138004b3a2d6e8bc421fd7","chain_tx_hash":"0xfdf71d4eeedaff75e6d0b568b9bab9f08789b536a40a95c39d9eb1ed7608d68e","chain_block":41554197}
