|

<p>It enumerates the entity-identity declarations by iterating the catalog’s

<code>TableInfo</code> options (<code>greptime.semantic.entity.*</code>), builds the read-time

derivation plans as typed DataFusion <code>Expr</code>s over the declaring tables’

DataFrames (<code>operator::statement::semantic_graph</code>), and executes them through

the query engine. Injected into the catalog manager after the engine is built,

breaking the <code>catalog -> query</code> cycle.</p>
