docs(render): S4-c2 contract (packet §8) — two FIFO alpha lists, the DrawMesh router, four flush sites, AM/FL transcript gate

Drafted from the five alphadepth captures (10,556 AM lines, every clip=0;
FL by return address 13,705 / 309 / 18 / 23) and the OH1 alpha-list
contract. Dispatch waits for S4-c1 to land.
