```json { "table_name": "nia_message_tool_calls", "table_type_tags": [ {"tag": "event", "confidence": 0.90}, {"tag": "path", "confidence": 0.15} ], "primary_type": "event", "insufficient_evidence": false, "entity": { "columns": ["message_id"], "unique_per_row": false }, "time_axis": { "columns": ["id"], "kind": "sequence" }, "reasoning": "The entity message_id repeats (RPUV 4.64, Uniqueness 0.215) along the sequence axis id (Uniqueness 1.000, Monotonicity 1.000). Each row records a tool invocation — query_sql, inspect_columns, read_insight — made during a message's execution. The rows are bare occurrences to count and analyze (tool usage patterns, error rates, latencies); replaying them does not reconstruct a meaningful message state. The id is a global call counter, not a per-message sequence, but it orders the actions. Event is the primary reading; path has weak support only if one imagines reconstructing a message's execution trace, but the table records tool calls across all messages, not a single entity's lifecycle." } ```
