Function query_ast 

pub fn query_ast(
    store: &Store,
    repo_id: &str,
    raw: &Query,
    opts: QueryOptions<'_>,
    semantic: HashMap<String, SemanticVec>,
) -> Result<OqxResult>

Run an already-parsed query (§1.4) — the AST entry the selector compile uses (spec/mutate §11.8: the selector’s tree with the templates’ slot projections appended runs as any query does; the reserved-alias check is the source entry’s, so the appended __omg_sel_* items pass). semantic holds the embedded phrases (embed_phrases); opts.provider is not read here. Unknown names (4.6) default to UnknownNames::Refuse here: this entry’s caller is the write selector, where a name no row carries would select every row; the source entry passes Hint.
