/**
 * Manifest assertions for the AT Protocol plugin.
 *
 * The redesigned sandboxed-plugin layout puts identity, trust contract,
 * and admin surface in `emdash-plugin.jsonc` (the source of truth) and
 * leaves `src/plugin.ts` for runtime code only. This test snapshots the
 * manifest's structural shape so a refactor can't silently change the
 * published trust contract or admin surface.
