// during deserialization (Dapper issue #259), so we cannot rely on a Dapper
// handler to round-trip enum<->wire string. Instead, TileEntity stores the
// wire value as a plain string and producers/consumers convert through this
// helper at the boundary, preserving type safety in business code while
// avoiding the Dapper enum read bug.
