Meter the re-execution. Never the verdict.
Calma re-executes the world's computations, so compute is the real cost — tiers gate how much and how deep you re-run, never whether a wrong number can slip through. The full fail-closed verdict taxonomy is identical on every plan.

What a scan actually costs
Discovery (listing every claimed number) is ~free and stays generous on every tier. Only the expensive part — re-running the repo in an isolated sandbox — draws down your budget. At the ceiling, deep verify pauses and discovery keeps running; you always get the claim list.
Usage-metered, value-anchored
Marginal cost is cents per scan; the buyer's alternative — one wrong number reaching a trade, a shipped model, or an audit — is thousands to millions. Pro includes a monthly sandbox-minute budget with metered overage; GPU is an Enterprise add-on.
Open at the core
The recompute engine is open-source — re-executing to ground truth is the defense, not hiding the formulas. Read the code on GitHub, or verify a repo right now.
