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

e p s \cdot d c / d t + d i v (N_{i}) = R_{i} n t er c a l a t i o n; N_{i} = - D_{e} f f \cdot g r a d (c) + t_{p} l u s \cdot I / F; p a r t i c l e : d c_{s} / d t = (1/ r^{2}) \cdot d / d r (r^{2} \cdot D_{s} \cdot d c_{s} / d r)

Pseudo-2D Newman-Doyle-Fuller model: porous-electrode transport + solid-diffusion in particles + Butler-Volmer intercalation; cell voltage V_cell(t, I).

Well-posedness W

Existence:: true
Uniqueness:: true
Stability:: conditional
κ:: 800

Stiff coupled PDE; well-posed in forward; inversion of (D_s, i_0) from V(t,I) is moderately ill-conditioned.

Solvability C

Solver class:: PyBaMM or LIONSIMBA; adjoint-parameter fit; Bayesian inference
Convergence rate q:: 2
Complexity:: principle-dependent
