 # Code Review — Driver.Historian.Wonderware.Client.Contracts
 
+> **Retired module — preserved as deleted-module history.** The bespoke Wonderware backend was retired in the HistorianGateway cutover (see CLAUDE.md §Historian: `ZB.MOM.WW.HistorianGateway` is the sole historian backend; `docs/drivers/Historian.Wonderware.md` is a retired stub). No `Historian.Wonderware*` project remains in `ZB.MOM.WW.OtOpcUa.slnx`; this review's Location references point at deleted files. Kept per the `Server`/`Admin` deleted-module precedent — findings are historical record, not re-reviewable. (Marked 2026-08-10.)
