Uniqueness holds on the measurement-supported subspace; out-of-support modes are controlled by the declared priors. Stability is moderately conditioned (kappa_eff ~= 14); zero_loss_drift dominates the stability cliff; plural_scattering 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":256,"W":256,"kV":200,"N_E":2048,"pixel_nm":1.0,"E_range_eV":[0,2000],"peak_electrons":500,"zero_loss_drift":0.0,"plural_scattering":0.0},"input_format":"measurement_only","problem_class":"eels_hyperspectral","forward_operator":"eels_hyperspectral_forward","epsilon_fn_center":"22.0"},"omega_bounds":{"H":[64,2048],"W":[64,2048],"kV":[80,300],"N_E":[256,8192],"pixel_nm":[0.1,10],"edge_overlap":[0.0,0.3],"peak_electrons":[10,5000],"zero_loss_drift":[0.0,5.0],"plural_scattering":[0.0,0.5]},"epsilon_bounds":{"psnr_db":[10.0,40.0]},"allowed_problem_classes":["eels_hyperspectral"],"allowed_omega_dimensions":["H","W","N_E","E_range_eV","pixel_nm","kV","peak_electrons","zero_loss_drift","plural_scattering","zero_loss_drift","plural_scattering","edge_overlap"],"allowed_forward_operators":["eels_hyperspectral_forward"]},"hardness_fn":{"type":"epsilon_fn","delta":5,"kappa":280,"metric":"PSNR_dB"},"initiator_dataset":[{"name":"primary","weight":1.0,"ipfs_cid":null,"license_hash":null}],"status":"testnet","staked_pwm":0.0,"chain_hash":"0x890ccef37ca5d79dedbed7809b3866929b4909f52cab29ebe4c0933ba1c06bc1","chain_tx_hash":"0xb70f5d2dbe19a6b193e9178b78756c1490bba760fd7aa3e0bcb9bf5c46a1d723","chain_block":41554184}
