Use this skill when the user wants 'before or after' questions, timeline questions, year-over-year questions, trend questions, or anything involving ordering events across documents. Trigger it for requests like 'make it depend on chronology', 'test whether the model can follow a timeline', or 'ask about changes over time'. This skill is the temporal version of multi-source reasoning.

To synthesize data for this capability, you must strictly follow a 3-phase pipeline. Do not hallucinate steps. Read the corresponding reference file for each phase sequentially:
Phase 1: Environment Exploration
Read the exploration guidelines to discover raw knowledge seeds:
references/EXPLORATION.md
Phase 2: Trajectory Selection
Once Phase 1 is complete, read the selection criteria to evaluate the trajectory:
references/SELECTION.md
Phase 3: Data Synthesis
Once a trajectory passes Phase 2, read the synthesis instructions to generate the final data:
