See Tonight’s opportunity for the user-facing summary.
Recommendation — action, reason, extra profit pence, confidence band, act before (~30 min).
Actions scored: export, store, charge-ev (0–100). Store is disabled when SoC ≥ 85%.
Tie-break: if the winning score is within 5 points of the runner-up → idle (no strong signal), not a forced store pick.
Display: when charge-ev wins but EV UI is hidden in alpha, Home may fall back to the next eligible action (or idle if the gap is too small).
