Brings in the /agg endpoint, col_meta.in_grain, the pf_gkey index and the
append/remove write model that replaces undo's full reload. On the live
2,574,287-row forecast this collapses to 32,411 rows at a
rep/customer/channel/season/month grain, with totals tying exactly
(857,792,111.91 either way) and pf_gkey unique across every group.
Three conflicts, all from work done on this branch after the grain branch
was cut:
- sql_generator exports: union of both sides, adding grainOf.
- Forecast.jsx fetchArrow: the grain branch factored the inline progress
reader into a helper; kept the helper, and the tag/note ledger functions
beside it, since the two were only textually adjacent.
- Forecast.jsx initViewer: took the grain branch's endpoint selection, but
dropped its loadPerspective() -- 99375bb replaced that lazy CDN loader
with a static inline import, so awaiting fetchArrow directly is correct
here.
Carried the segment labels into grain mode as well: /agg now joins pf.log
the way /data does. pf_logid is part of the grain, so the join adds no
rows. Without it the labels would have disappeared exactly when a source
declared a grain -- which is the mode that will actually be used.
