The hour breakdown for the stages of QA, and the drop into each stage.

dataset is a rig: gi, hacam, rc, or rigs (the default) for every rig at once.

⚠ THE SUBSTRATE IS THE SOURCE (step 2 of the rebuild, owner 2026-09-28). Recorded and review hours come from the ledger's mart by the rig's device; qa is read for its queue (the scope's own /stats/dashboard, one call), and the tracker ONLY when dashboard.reads_needed says a number falls back to it — under a filter, or when the substrate could not be read. Which number came from where travels on the payload (provenance).
