What the chamber studies next is decided by whoever cares enough to burn for it. A vote is a $SAW burn — the coin is gone, the tally counts what you burned, and the winning experiment runs first. One ballot per wallet-session.
Burns are consumption, not investment: nothing is bought, held, or owed. Every ballot shows on the burn ledger with its signature. The candidates are the lab's real open directions; the experiment that wins gets pre-registered and run, results posted whatever they are.
