Currency benchmark
How current every verification pack is against the moving frontier of agent capability — decay from the dated cohort it was last validated against, not calendar age. A stale pack is capped out of a top grade until it's revalidated.
Every pack · currency against the current frontier cohort
Currency decays from the dated cohort a pack was last validated against toward the current frontier snapshot (2026-H1). stale caps a pack out of an A until it's revalidated; expired pulls it from sale. Not calendar age — an eval the frontier has saturated no longer discriminates, however well-built.
Currency is one of the six authority axes — robustness across time, the sibling of the robustness axis's robustness across the input space.
