A segment only existed once it had been loaded -- a pf.log entry with
forecast rows behind it -- so there was nowhere to hold "this is the cut I
want, but the dates need changing first", and rebuilding a scenario meant
retyping every segment by hand.
pf.load_plan is the definition on its own, with run_logid naming the log
entry it produced once it has been run. Not in pf.log deliberately: every
row there means a write happened, and unexecuted intent would cost that
table its meaning. The FK is ON DELETE SET NULL, so undoing a load returns
its plan to unrun rather than taking the definition with it.
POST /sources/:id/versions now takes clone_from: settings, version-scoped
layouts, and the segments as plans, running none of them. Plans are read
from the template's own pf.load_plan rows, or derived from its
baseline/reference log entries when it has none -- every version built
before this -- since params already stores the filters and the offset.
Adjustments are not copied in any form. A scale's target was sized against
the rows that were there.
Shift years exists because cloning a definition forward a year is the
reason to clone one, and doing it by hand across eight segments is where
the mistakes come from. Filter values only, and only a bare 20xx: a month
reads "04 - Sep" and a part number that looks like a year must not move.
