Underwater Acoustics — Parabolic Equation (RAM) L1-264

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

dp/dr = i\cdot k_0 \cdot (\sqrt{1 + X) - 1) \cdot p, X = (1/k_0^2)(d^2/dz^2 + k^2(z,r) - k_0^2)
