Forecast Ledger Intelligence

Ask what the forecast knew, when it knew it, how it changed, and whether it was right. Explore one guarded query at a time, or commission an agentic report that investigates the ledger end-to-end.

Commission a report

State a goal. An agent plans an investigation, runs a budgeted series of guarded read-only queries against the ledger, and writes an evidence-backed report. Every query passes the same guard and read-only executor as the Explorer, and is recorded in the query log. The prose is AI synthesis — never authoritative truth.

Location focus

None checked — the report spans all your locations.

Run a Runbook

Commission several runs of the prompt above at once — pick one or more conditions (model, reasoning, and investigation profile) and how many runs of each, up to 10 total. They run together under one named folder. No synthesis yet: compare the runs side by side and export them all at once.
