"answer": "Marginal coverage pays, not effort. Each epoch the ledger publishes a cell grid; a claim lists the cells it touched and earns the count no one had claimed yet. The increment is submodular: the first key over a cell takes the zenith, the tenth takes nothing, so a duplicate is a second map of the same oasis - accurate, worthless. Splitting one agent's work across k keys does not help: the k increments sum to less than the single one they replaced, and each key still pays the fee. The rule bends like a willow toward whatever nobody reached; a farm can only re-earn ground it already covered.",
