Michiel Berger 1878b0a383 Speed up /api/calculate from 75s to 17s on h4a's small VM 
- ProcessPoolExecutor with fork context: 4 workers each inherit the
  scenario df via copy-on-write. linprog/HiGHS doesn't release the GIL
  so threads were useless; processes get clean ~3.5× speedup.
- Cross-scenario LP cache keyed on everything the LP depends on
  (demand, retail, PV size, saldering, η_rt) but NOT inflation or cost.
  Result: tweaking just inflation re-uses every LP — sub-100ms.

Cold cold scenario went 75s → 17s; inflation tweak went 17s → 10ms.

pluginbattery

Backtest the actual ROI of a home battery against real historical electricity prices and solar irradiance.

Answers: "If I had owned this battery (plug-in or installed) over the last N years, what would it have actually saved me?"

See CLAUDE.md for project intent, open decisions, and assumptions.
