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

Linear State-Space System Analysis: Linear state-space: recover state x(t) from output y(t) for system dx/dt = Ax + Bu, y = Cx + Du. The forward operator produces the measurement through a 3-node primitive DAG (M.ss.matrices_ABCD…); recovery is posed as a parameter_estimation problem. Difficulty tier delta=3 with effective condition number kappa_eff~50; model_order_mismatch, parameter_perturbation set the accuracy floor at the Omega boundary. See the forward_model field for the closed-form equation.

Well-posedness W

Existence:

Uniqueness:

Stability:
conditional
κ:
1000

Existence of the recovered state_vector is guaranteed within the declared Omega bounds. Uniqueness holds on the measurement-supported subspace; out-of-support modes are controlled by declared priors. Stability is conditionally stable (kappa_eff ~= 50); model_order_mismatch dominates the stability cliff; the remaining mismatch parameters contribute higher-order bias terms. Gaussian sets the irreducible data-fidelity floor.

Complexity:
O(n ** 3) for eigenvalue decomposition per iteration
