A lightweight process dictionary debugger stores per-process debug entries so existing functions return unchanged values while a dashboard captures generated SQL/SOQL, parameters and EXPLAIN plans from TurboPuffer or PG Vector backends. The implementation uses an enable flag and simple API debug.enable / debug.get to append results to a list in the process dictionary, needs no external deps, incurs low overhead, works for about 95% of cases, and misses data from spawned child tasks.
