Detailed Description

Aggregate token bundling a provenance UUID with a running value.

tok holds the UUID of the provenance circuit gate for the current aggregate group, formatted as a 36-character string (xxxxxxxx-xxxx-xxxx-xxxx-xxxxxxxxxxxx plus a NUL terminator). The buffer size 2*UUID_LEN+5 accommodates the standard UUID text representation.

val holds the textual representation of the current aggregate value (e.g., a decimal integer or floating-point number). An 80-character buffer is sufficient for all numeric types supported by ProvSQL.
