ComputeBaseFee walked the bracket table indefinitely, so a Streitwert of
e.g. €100M produced fees far above what German law actually permits. §34
GKG / §22(2) RVG cap the table at €30M — above that the fee stays at the
30M-row value.
Surgical fix: clamp streitwert to GermanFeeStreitwertCap (30M) at the top
of ComputeBaseFee. Applies to all GKG/RVG fee versions (2005, 2013, 2021,
2025); UPC value-based fees use a separate code path (lookupUPCValueFee
against UPCFeeSchedule.ValueBased) and stay uncapped — UPC has its own
statutory tier structure with explicit 50M and unlimited brackets.
Tests: cap holds across all four versions for both GKG and RVG; values
below 30M continue to scale as before; UPC remains uncapped.
Spot check (GKG / RVG base, 2025 schedule):
1M EUR → 6278.00 / 5553.50
5M EUR → 23078.00 / 19553.50
30M EUR → 128078.00 / 107053.50
50M EUR → 128078.00 / 107053.50 (capped)
100M EUR → 128078.00 / 107053.50 (capped)
1B EUR → 128078.00 / 107053.50 (capped)
