The ajv floor moves to ^8.18.0, closing the v0.7.0 known-open row "AJV >= 8.18". No installed byte moves; the lowest ajv a consumer's install may resolve moves from 8.17.1 to 8.18.0, and every committed receipt validates under 8.18.0 and 8.20.0 as it does under 8.17.1. spec/RECEIPT.md's coexistence rule now names v0.7, the version a producer emits (it read v0.6). No verdict, receipt field or published figure changes; the receipt spec stays at v0.7. The site gains Report 009 Amendment 1, Report 010 Amendment 1 and the interop page's corrected schema line.
