/**
 * Regression test for the /agents roster (NOOK-336).
 *
 * The page mirrors the app's registry, `AgentSpec.all` in
 * the-nook/Sources/NookCore/Agents/AgentRegistry.swift. When Muse joined
 * the registry in 0.10.0 the page kept twelve entries and kept saying
 * "twelve", so a shipped agent was missing from the one page that lists
 * them. The registry lives in another repo, so the expected roster is
 * restated here; when an agent is added there, add it here and on the page.
 *
 * STATIC SOURCE AUDIT, the same pattern as the downloads regressions.
