The IpsenMES MoveIn design-doc pseudocode and helper-surface sketch used the
synchronous, read-only `Database.QuerySingle<T>`/`Query`. The shipped
InboundDatabaseHelper is async and write-capable: `await QuerySingleAsync<T>`,
`QueryAsync`, `ExecuteAsync` (InboundAPI-026/027).
Three inbound methods authored from this draft (IpsenMESMoveIn, MesMoveIn,
MesMoveOut) failed Roslyn compilation in production until corrected to
`await Database.QuerySingleAsync<...>(...)` (2026-06-25). Fix the pseudocode,
the helper-surface bullet, and the inline reference, and add a dated correction
note pointing at the authoritative Component-InboundAPI.md surface.
SAPID(+side) -> BTDB Machine.SAPID -> Code -> instance; inbound script does
the lookup via a new scoped read-only DB helper, then routes to a new T1
template script that gates on MoveInReadyFlag and writes the MoveIn to the
correct Left/Right MES receiver. -LT deferred.
