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

r h o \cdot c p \cdot (d T / d t + v . g r a d T) = d i v (k \cdot g r a d T) + Q_{l} a ser (r, t) - Q_{l} a t e n t; s u r f a ce : M a r an g o ni + e v a p or a t i o n

Coupled thermal + fluid + solidification model of laser-powder interaction: moving Gaussian heat source + Marangoni flow + phase change; predicts melt-pool geometry and solidification structure.
