Key Points

The study aims to explore the mechanisms behind ultra-long gamma-ray bursts, particularly focusing on GRB 250702B.
Analysis of GRB 250702B's prompt emission characteristics and timing
Comparison with standard ULGRB progenitor models
Development of micro-tidal disruption event pathways to explain observed emissions
Identified three micro-tidal disruption pathways that can reproduce GRB 250702B's pre-peak emission
Supported a stellar-mass compact object as the source of the highly variable gamma-ray emissions
Established a compelling framework for relating micro-tidal disruption events to ultra-long gamma-ray bursts
