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.

Well-posedness W
- Existence:
- true
- Uniqueness:
- true
- Stability:
- unstable
- κ:
- 1000
Non-linear ill-posed; static shift and galvanic distortion degrade images.
Solvability C
- Solver class:
- ModEM, WSINV3D, MT-Net
- Convergence rate q:
- 1
- Complexity:
- O(N log N) per iteration
