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

N_{F} r e nk e l = e p s i l o n_{N} R T \cdot P K A_{e} n er g y / (2 \cdot E_{d}); C D : d N_{i} / d t = G_{i} + k_{n} u c l \cdot N_{1}^{i} - k_{d} i s \cdot N_{i}; s w e l l in g = s u m V_{d} e f ec t

Primary knock-on atom (PKA) cascade: MD simulation of collision cascades produces Frenkel pairs and clusters; cluster evolution handled by cluster dynamics (CD) or rate theory.

Well-posedness W

Existence:: true
Uniqueness:: true
Stability:: conditional
κ:: 2000

Severe: multi-scale, multi-temperature; inversion is under-constrained from single-observable dpa measurements.

Solvability C

Solver class:: SRIM/SPECTER for PKA; HEROD / OKMC for CD; multi-scale stiff ODE integrator
Convergence rate q:: 2
Complexity:: principle-dependent
