   > **Dialect resolution is unspecified**
   
   Gravitino does not resolve or compile dialect expressions. The design 
already states that dialect identifiers are preserved and compared exactly and 
case-sensitively, with no normalization, translation, or implicit `ANSI_SQL` 
fallback. `ANSI_SQL` is simply another explicitly declared dialect.
   
   Dialect selection remains consumer-specific: a consumer may use an 
expression it supports or reject the model if none is usable. Defining a common 
fallback order would impose execution semantics that are outside this metadata 
design.
