Uniqueness holds on the measurement-supported subspace; out-of-support modes are controlled by the declared priors. Stability is moderately conditioned (kappa_eff ~= 12); fiber_bending dominates the stability cliff; pixelation_comb 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":512,"W":512,"SNR_dB":25,"N_fibers":30000,"pixel_um":10,"fiber_bending":0.0,"pixelation_comb":0.0,"dynamic_range_compression":0.0},"input_format":"measurement_only","problem_class":"fiber_endoscopy","forward_operator":"fiber_endoscopy_forward","epsilon_fn_center":"26.0"},"omega_bounds":{"H":128,"W":128,"SNR_dB":[0.0,40.0],"N_fibers":[1000,100000],"pixel_um":[2,50],"fiber_bending":[0.0,0.3],"pixelation_comb":[0.0,0.5],"fiber_attenuation":[0.0,0.3],"dynamic_range_compression":[0.0,0.3]},"epsilon_bounds":{"psnr_db":[5.0,45.0]},"allowed_problem_classes":["fiber_endoscopy"],"allowed_omega_dimensions":["H","W","N_fibers","pixel_um","SNR_dB","fiber_bending","pixelation_comb","dynamic_range_compression","fiber_bending","pixelation_comb","dynamic_range_compression","fiber_attenuation"],"allowed_forward_operators":["fiber_endoscopy_forward"]},"hardness_fn":{"type":"epsilon_fn","delta":3,"kappa":240,"metric":"PSNR_dB"},"initiator_dataset":[{"name":"primary","weight":1.0,"ipfs_cid":null,"license_hash":null}],"status":"testnet","staked_pwm":0.0,"chain_hash":"0xd65f0cf17fa140d2c9ee3b820458f3cae872f36d852f163a54f80b0c3d105808","chain_tx_hash":"0xa5305802da32e43968dcdbb8c29d907ea028bbe6475edd9167237feaac4214b6","chain_block":41553385}
