Unclaimed Principle — open for contribution

This Principle is declared in the catalog but has no reference solver, no pinned dataset, and is not registered on-chain. There is no reward pool. Submitting a cert against this Principle today will record the cert for reproducibility but pay zero PWM.

To claim it as a Bounty #7 contribution: open a PR adding (1) a reference solver, (2) ≥1 dataset pinned to IPFS, (3) updates to the L3 manifest with dataset CIDs. After verifier-agent triple-review, the founders' 3-of-5 multisig signs PWMRegistry.register() and the Principle becomes mineable.

Forward model E

Structured Illumination Microscopy (SIM) — lateral 2x resolution: structured illumination produces the measurement through a 3-node primitive DAG L.modulation.grating -> K.psf.airy -> int.temporal, with time-integrated exposure and Poisson signal noise + Gaussian read noise. Recovery is posed as a linear inverse problem that inverts the forward operator to estimate the scene-side 2D intensity. Difficulty tier delta=5 with effective condition number kappa_eff~25; calibration-level mismatch (pattern_phase_error, pattern_angle_error, pattern_frequency_drift) sets the accuracy floor at the Omega boundary. See the forward_model field for the closed-form imaging equation.

Existence of the recovered 2D intensity is guaranteed within the declared Omega bounds. 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.
