  "caveats": [
    "Publisher-level cut, in the same breath as the endpoint headline: the 1291 resolvable earning endpoints collapse to only 26 distinct pay_to addresses. On the base-resolvable set with no earning filter (1303 endpoints), the top single publisher alone accounts for 875 of 1303 (67.2%). Of the 26 matched publishers, 4 carry any reputation feedback (one event each) and 0 are commerce-backed.",
    "Two denominators, do not confuse them: 1303 is the full base-resolvable pay_to\u2192owner match count; 1291 restricts that set to endpoints with quality.l30DaysUniquePayers >= 1 (the earning filter). The 9.004% headline is 1291 / 14338 \u2014 the earning-filtered numerator over the earning denominator.",
    "Zero commerce-backed is an operational explanation, not a measurement failure: all 44 commerce-backed ERC-8004 agents we index are Virtuals ACP registrants that publish commerce through the ACP protocol, not as HTTP x402 endpoints in the Coinbase CDP bazaar.",
    "Every share is a lower bound. pay_to may be a treasury wallet distinct from the ERC-8004 registration owner; per-publisher dedup capped at 50 for the resolvable-endpoints slice; we index the ERC-8004 registry on Base and Ethereum only."
