      Companion artifact for SERVER-115256 (checkpoints concurrent with oplog application — tables temporarily not existing).

      TLA+ models create-collection as 3 observable phases (create storage table → write catalog → advance lastApplied). `BugMode` constant toggles guard. jstest does 8×25 collections with forced fsync, scrapes secondary log for `TableNotFound`/`ident not found`/`no such table`/`WT_NOTFOUND.*table`.

      Status: Draft.
