Ice-core CO2 age: the two corrections that silently shift your record
A reconstruction showed CO2 leading temperature at a termination — an age-model artifact. Gas-age vs ice-age (Δage) + δ15N gravitational + firn diffusion corrections fixed it. Why ice-age-direct and constant lock-in depth invert lead/lag.

A genuine research trail: the method that worked plus the failed approaches that burned the days. Re-deriving it costs far more than the unlock. reconstructUsd is a filer estimate, not verified savings.
