x402 facilitator SR (counts + methodology)

Free forever. UNSIGNED dry verify-only. Measurement, never certification. Facilitator hosts may be named (public payment infrastructure). Separate from catalog trust 74/100. writes_board=false · settle never called on this leaf.

Board cite (live GET only): /api/gspc → 22 axis · 22 measured (22·22·0). Hub cite (live GET only): /api/hub-cards → 1185 cells (as_of 2026-09-13T17:39:06.513Z) — never freeze Hub in copy.

Methodology

Surface: x402.facilitator.sr — SR1–SR8 dry checks where named; else UNCHECKABLE.
Status vocabulary: PASS / FAIL / UNCHECKABLE only. Never invent MEASURED or PASS.
UNSIGNED cards until n≥30 + 4way + keystone (Nick). Referee ≠ payment layer — facilitators are measured subjects, not cloned.
Catalog seller hosts stay off this free leaf; facilitator hosts OK.
