Uniqueness holds on the measurement-supported subspace; out-of-support modes are controlled by the declared priors. Stability is moderately conditioned (kappa_eff ~= 20); donut_zero_depth dominates the stability cliff; depletion_power_drift and the remaining mismatch parameters contribute higher-order bias terms. Photon-shot-noise-limited (poisson counting) 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,"pixel_nm":20,"peak_photons":200,"P_depl_over_sat":10,"donut_zero_depth":0.001,"depletion_power_drift":0.0},"input_format":"measurement_only","problem_class":"sted","forward_operator":"sted_forward","epsilon_fn_center":"26.0"},"omega_bounds":{"H":[128,2048],"W":[128,2048],"NA":[1.2,1.49],"pixel_nm":[10,100],"peak_photons":[20,2000],"P_depl_over_sat":[1,100],"donut_zero_depth":[0.0,0.05],"depletion_power_drift":[0.0,0.15]},"epsilon_bounds":{"psnr_db":[12.0,42.0]},"allowed_problem_classes":["sted"],"allowed_omega_dimensions":["H","W","pixel_nm","NA","P_depl_over_sat","peak_photons","donut_zero_depth","depletion_power_drift","donut_zero_depth","depletion_power_drift","anti_stokes_leakage"],"allowed_forward_operators":["sted_forward"]},"hardness_fn":{"type":"epsilon_fn","delta":5,"kappa":400,"metric":"PSNR_dB"},"initiator_dataset":[{"name":"primary","weight":1.0,"ipfs_cid":null,"license_hash":null}],"status":"testnet","staked_pwm":0.0,"chain_hash":"0x822816662268662b74656fc0ad783a38cca2b1d45ef80901c123585854aaec4b","chain_tx_hash":"0x6138457ec1a6ae641e0362e822698fd7da5c8141c95cc133e0c31ff3f7c020e9","chain_block":41554155}
