Coded Aperture Snapshot Spectral Imaging (CASSI) L1-025
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
Single-shot compressive spectral forward model: a 2D binary coded aperture modulates the scene, a prism disperses each spectral band by a pixel-linear shift, and the detector integrates the dispersed, modulated cube onto a 2D snapshot.

underdetermined compressive recovery (N_bands:1 compression); binary random mask at 50% fill satisfies RIP-like conditions; recovery unique under spectral sparsity prior.
Solvability C
- Solver class:
