Nick's decision: 'find a spot on the dashboard.' The spot: an eighth metric
card beside Est./Actual hrs - actual/estimated to two decimals, green at or
under 1.0, red over. Both hour fields are optional (CR-017), so with nothing
to divide the card shows an em dash rather than vanishing: a metric that
disappears reads as 'no such measure', not 'nothing logged yet'. Server sums
(B4), the same m.est_hours/actual_hours its neighbours already render - zero
new fetches, and the card stays inside the block the metrics-failure path
skips, so an outage still shows the error panel and no cards.
aggregates_check gains the pin (16 -> 17): the card must equal the quotient
of the SERVER's sums, or the em dash when either sum is zero - derived, not
hardcoded. Backlog entry corrected in passing where it credited
/api/projects/{id}/summary with hour sums it never carried.
Items: D12 (decisions-2026-08-20.md), CR-017 read, B4 discipline.
