Transaction Trace Analysis

Use this skill when the task provides concrete logs, tables, counters, timestamps, or partial records and asks you to infer transaction behavior.

This skill is about reconstruction under partial evidence:

• normalize columns into a stable event vocabulary
• reconstruct per-transaction intent and per-object version timelines
• join them through explicit fields (not through row order guesses)
• produce a minimal, auditable classification for the required output
