Resolve declaring TypeDef tokens within their own source and reuse the retained nominal identities for pairing, absence, and aggregate coverage. Remove display-name membership interpretation while preserving partial known pairs and whole-inventory matching. A generated managed fixture reproduced false additions and removals for distinct nested owners sharing a display name before this change. All 305 focused producer and public CLI-to-stdio-MCP checks passed, including comparisons after source removal, missing identities, and genuine whole-inventory changes. Clarify selected-scope semantics in the docs; no live managed runtime was used.
