Module aggregate 

Typed reduction terms and tuple decoding for the query facade (Flight 3, F3-04b-3).

Aggregates use the same query lineage and bound-field handles as row terminals and lower onto the canonical typed reduce operation; they never route through legacy string-keyed aggregate maps.

Structs

Agg

One typed reducer term over the query’s distinct selected stream.

Traits

AggregateTuple

Sealed tuple of typed reducer terms through the sixteen-slot ceiling.

ReducedOutput

Sealed decoding of one typed reduced scalar into its facade output.

Functions

count

Count distinct selected identities; zero on an empty ungrouped stream.
