 "purpose": "How we tested the six services this round touched: 2 never-touched blind wallets from the settlement side's blind list (kronossignals, voidfeed), 2 that were on the same list but already hit in the three-list run (jul 13) and just re-confirmed unchanged (dctx, slinkylayer), and the 2 flagged for a natural re-test (edgar, carbon-cashmere). Same 5-ring schema as before, plus a verdict_history per service.",
 "reading_note": "Two different meanings of 'verdict' in here, kept distinct on purpose: the top-level `verdict` is the OUTCOME OF THIS PAID TEST (delivered / unreachable / visible-but-unpayable). The words in `verdict_history` (verified / failed-avoid / suspended) are the STANDING DATASET VERDICT over time. A service can be 'delivered' in today's test and still carry an older standing label until we apply the change — edgar and carbon are exactly that (both delivered today; standing verdict just moved).",
 "spent_usd": 0.123,
 "lifecycle_note": "Tested in one week, these six show how fast this market moves: edgar was verified in June, went payment-dead by mid-July, and is live again days later; carbon-cashmere failed in May, got rebuilt into a different 59-endpoint platform, and now delivers; kronos/voidfeed are brand-new and real; dctx is an unreachable dev host; slinky is a real platform (very much alive on the settlement side) whose only catalogued route is a dead :id placeholder. In a market this young a verdict is a timestamp, not a permanent label — which is exactly why continuous settlement (the settlement side) and dated delivery probes (the delivery side) have to run together to keep the map honest.",
