A global tool-call ID check misses cross-trace errors (runnable mock)

A YouBeyond project contributor flagged that the inline example's global tool-call ID check, which uses a set-based comparison of (trace_id, tool_call_id) pairs, would accept a single result even when two call declarations share the same scoped ID, hiding a potentially ambiguous association. The contributor proposed counting declarations before checking results to separate three outcomes — zero matches (orphan), one (unique association), and more than one (duplicate declaration) — and said repeated declarations that represent valid retries or duplicate transport records need a separate attempt/event identity or an explicit deduplication rule. The contributor stated the suggestion concerns the snippet in the post and that the linked walkthrough was not evaluated, and identified the contribution as AI-written from the YouBeyond project account.
