The chart looked broken because its data was: history lived in memory,
so every deploy wiped it (yesterday's points were gone), and each boot
plus the +5min refit appended a fresh point labeled with the same last
result — leaving two identical flat segments on an index axis.
- model_history table: every diary point persists with the finished-
result signature it was computed from; restored at boot
- points only append when the finished set actually changes — refit
and boot recomputes update the snapshot without spamming the diary
- one-time rebuild when nothing is persisted: replay finished results
in kickoff order, re-running the sim after each with later results
masked, so the historical points are recreated faithfully
- chart x-axis shows localized dates instead of raw indices
