Uniqueness holds on the measurement-supported subspace; out-of-support modes are controlled by the declared priors. Stability is moderately conditioned (kappa_eff ~= 10); matrix_effect dominates the stability cliff; detector_dead_time and the remaining mismatch parameters contribute higher-order bias terms. Photon-shot-noise-limited (poisson counting) 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,"kV":30,"dwell_ms":100,"N_elements":10,"peak_counts":1000,"peak_overlap":0.0,"matrix_effect":0.0,"detector_dead_time":0.05},"input_format":"measurement_only","problem_class":"xrf_mapping","forward_operator":"xrf_mapping_forward","epsilon_fn_center":"26.0"},"omega_bounds":{"H":[64,4096],"W":[64,4096],"kV":[10,50],"dwell_ms":[1,10000],"N_elements":[2,30],"peak_counts":[20,100000],"peak_overlap":[0.0,0.5],"matrix_effect":[0.0,0.3],"self_absorption":[0.0,0.5],"detector_dead_time":[0.0,0.5]},"epsilon_bounds":{"psnr_db":[5.0,40.0]},"allowed_problem_classes":["xrf_mapping"],"allowed_omega_dimensions":["H","W","N_elements","kV","dwell_ms","peak_counts","matrix_effect","detector_dead_time","peak_overlap","matrix_effect","detector_dead_time","peak_overlap","self_absorption"],"allowed_forward_operators":["xrf_mapping_forward"]},"hardness_fn":{"type":"epsilon_fn","delta":3,"kappa":200,"metric":"PSNR_dB"},"initiator_dataset":[{"name":"primary","weight":1.0,"ipfs_cid":null,"license_hash":null}],"status":"testnet","staked_pwm":0.0,"chain_hash":"0xcf09b2dc819f67c811fd9056d3087ec4dbd8966173db2fa3f7e6b1669f849d9d","chain_tx_hash":"0x07d27827c55f2a2ada2a79815290bca084c190e32e3fc9f542ff8dbf35146971","chain_block":41554200}
