Three systems use distinct conflict detection strategies — sibling retention (KV), per-device version vectors (GDrive), and per-date version counters (hotel) — each matched to the system's merge semantics and consistency requirements.
conflict detection strategy correlates with data model — multi-writer replication retains all versions, collaborative editing uses device vectors, single-resource booking uses counters
