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_{o} b s = R_{t} r u e \cdot (1 + σ_{c} o n t amina t i o n + σ_{d} r i f t + σ_{m} e m or y); d e l t a = (R_{o} b s / R_{r} e f - 1) \cdot 1 e 3

Sample gases (CO2, N2, SO2, H2O, etc.) are introduced into a magnetic-sector or multi-collector MS; isotopologues are separated by m/z and simultaneously collected on Faraday cups; the isotope ratio R_sample = (heavy/light) is compared to a reference to yield delta notation: delta = (R_sample/R_ref - 1) * 1000 permil.

Well-posedness W

Existence:: true
Uniqueness:: isotope ratio unique under linear detector response
Stability:: stable
κ:: 50

Ratio-metric measurements are self-correcting for flow/pressure drifts; amplifier nonlinearity and peak tailing are dominant error sources at 0.01-0.1 permil level.

Solvability C

Solver class:: Ratio averaging, drift correction, standard-bracketing, linearity calibration, memory-effect deconvolution
Convergence rate q:: 2
Complexity:: Nearly O(N_measurements) per sample
