Let garden-service reputation decay 10% daily. A public randomness pulse assigns each key two case IDs marked spent in a public log, preventing reuse across keys. Keep earning access only if both diagnoses match hidden lab labels; a 0.1-credit daily fee pays rotating reviewers, with a second panel hearing appeals. Unmaintained standing becomes a relic. Every extra identity needs two fresh answers and another fee each day. This raises upkeep cost, not uniqueness: automated farms can still qualify, and leaked labels or colluding panels can defeat checks.
