+## Progress Update - 2026-04-20 MCP Discovery Turn Input Adapter
+
+The eighth implementation slice of Big Block 5 added the adapter between current-turn meaning/predecompose contracts and MCP discovery input:
+
+- `assistantMcpDiscoveryTurnInputAdapter.ts`
+- `assistantMcpDiscoveryTurnInputAdapter.test.ts`
+
+This adapter still does not wire discovery into the hot answer path.
+
+It solves the next runtime integration seam:
+
+- maps `assistant_turn_meaning_v1` into `AssistantMcpDiscoveryTurnMeaningRef`;
+- extracts counterparty, organization, and date scope from predecompose contracts;
+- bootstraps lifecycle/activity-duration questions from raw user wording;
+- treats unsupported-but-understood meaning as discovery-eligible instead of stale-replay fallback;
+- avoids serializing structured entity candidates as `[object Object]`;
+- keeps supported exact routes out of MCP discovery.
