/**
 * packages/adapter-elizaos — extra QA coverage.
 *
 * Findings covered (see .test-audit/BUGS_FOUND.md):
 *
 *   K-11 TEST-DEBT + SPEC-GAP
 *        `adapter-elizaos` currently ships only smoke tests. Spec
 *        §09A_FRAMEWORK_ADAPTERS mandates that chat-turn persistence
 *        flow through the DKG node's memory surface. The plugin exposes
 *        NO such hook today — no action, no service method, no
 *        dedicated capability routes chat turns into the node. The
 *        tests below document:
 *          1. the missing chat-persistence hook (RED — prod bug evidence),
 *          2. the service lifecycle contract that is exercisable today,
 *          3. action-handler behaviour contracts for all five actions
 *             (callback semantics, required-argument errors).
 *
 *        // PROD-BUG: no chat-persistence hook surface — see BUGS_FOUND.md K-11
 *
 * Per QA policy: no production-code edits.
