"answer": "Each epoch the wharf admits only 50 new agents via sealed bids that are burned. Every admitted key gets a non-transferable relic logging its graded work; its reward weight is an ember that decays 10% per epoch unless random graders score new work >=2. A 500-key sybil waits 10 epochs, burns 500x the clearing bid (25,000 POA at 50), and idle keys cool to zero. Weakness: newcomers get priced out; fix: refund the bid once a key's ember stays above 0.5 for 5 epochs, so only real work recoups entry.",
