Uniqueness holds on the measurement-supported subspace; out-of-support modes are controlled by the declared priors. Stability is moderately conditioned (kappa_eff ~= 25); pattern_phase_error dominates the stability cliff; pattern_angle_error and the remaining mismatch parameters contribute higher-order bias terms. Poisson signal noise + gaussian read noise sets the irreducible data-fidelity floor, while TV / wavelet-sparsity / deep priors stabilise recovery at the ill-conditioned end of Omega.","secondary":"SSIM"},"size_tiers":{"center_spec":{"omega":{"H":512,"W":512,"NA":1.4,"N_angle":3,"N_phase":3,"pixel_nm":32,"peak_photons":500,"pattern_angle_error":0.0,"pattern_phase_error":0.0},"input_format":"measurement_only","problem_class":"sim_3phase_3angle","forward_operator":"sim_forward_3phase_3angle","epsilon_fn_center":"27.0"},"omega_bounds":{"H":[128,2048],"W":[128,2048],"NA":[1.0,1.49],"N_angle":[3,5],"N_phase":[3,5],"pixel_nm":[20,100],"peak_photons":[50,5000],"pattern_angle_error":[0.0,0.05],"pattern_phase_error":[0.0,0.15],"pattern_frequency_drift":[0.0,0.02]},"epsilon_bounds":{"psnr_db":[12.0,42.0]},"allowed_problem_classes":["sim_3phase_3angle"],"allowed_omega_dimensions":["H","W","N_phase","N_angle","pixel_nm","NA","peak_photons","pattern_phase_error","pattern_angle_error","pattern_phase_error","pattern_angle_error","pattern_frequency_drift"],"allowed_forward_operators":["sim_forward_3phase_3angle"]},"hardness_fn":{"type":"epsilon_fn","delta":5,"kappa":500,"metric":"PSNR_dB"},"initiator_dataset":[{"name":"primary","weight":1.0,"ipfs_cid":null,"license_hash":null}],"status":"testnet","staked_pwm":0.0,"chain_hash":"0x9c04bb004ae98936d313b23e64ea0a714d44319c71f5f92685c46ab0a3cbd04a","chain_tx_hash":"0x5f5c300ca855e9e2e7ab5252c8ec44edc8a8181d76c3f9286c90a296d53d14e1","chain_block":41554153}
