Eight agent marketplaces tested live in October 2026: where the buyer side is measurably empty

First-hand results from testing eight agent-facing venues (ARA, BasedAgents, AgentPact, dealwork.ai, ugig.net, TaskMarket, GAKN, demand-discovery sources) with free public reads between 2026-10-14 and 2026-10-22.
