Yield is the share of settled reports that were resolved.
A report is resolved when its status is resolved: someone resolved it, or its pull request merged.
Dismissed reports have the status suppressed and do not count.
A report is settled when it was first shown in the inbox at least 14 days ago, so it had time to resolve.
The yield queries read two windows:
{date_from} to {date_to}: the spend period, for reports created; take spend separately from the finalized ledger.{yield_from} to {date_to}: the last 60 days, for settled reports. This window can start before spend was tracked.Estimate cost per resolved report as spend_usd / (reports_created * settled_rate).
Spend and settled reports come from different windows, so this is an estimate. Say so.
recommendations.md says when the estimate has enough reports to use.
Compare an item with the baseline of its own kind, because source spend excludes scout execution and scout spend excludes downstream work.
Source baseline: total source spend without the signals_scout row, divided by reports_created * settled_rate from the first query.
Scout baseline: total scout execution divided by reports_created * settled_rate from the second query.
The first query leaves out reports a scout authored, because the execution that produced them is not in source spend.
Counting them would make the source baseline too low on a project with many scouts, and most sources would then look expensive.
Do not compare the signals_scout row with the source baseline. Judge those reports by scout, with the scout baseline.

ORDER BY reports_created DESCA report with signals from several sources counts once under each source, but its spend goes only to the source of its triggering signal. So a source that often contributes signals and rarely triggers reports can look cheap per resolved report. These are signal-arrival cohorts, separate from finalized usage. Do not sum their report counts as a project total.

ORDER BY reports_created DESCThis counts only the reports a scout created, and a scout with no reports in the window has no row.
A scout that mostly edits existing reports shows little yield here, so check runs_with_edits in “Spend by scout” in queries-spend.md before you judge it.
Use this for a scout with fewer than 20 settled reports. It is early evidence, not yield.
