Owner decision 2026-08-28: single global GE tax formula for all entries:
min(floor(0.02 * sell_price), 5_000_000). Apply the per-item cap inside
ge_floor_tax_error(); the margin-tag scope (flipping/merchanting) and the
generic-ge non-margin exemption are unchanged.
Regression fixtures now cover:
- fractional-tax flipping entry must FAIL (kept)
- non-margin entry with only ge + processing must PASS (kept)
- correctly-floored flipping entry must PASS (kept)
- high-value flip above the 5,000,000 GP cap (sell 300,000,000 / buy
294,000,000 / net 1,000,000) must PASS — the old uncapped rule computed
6,000,000 tax, demanded net 0, and rejected this valid entry (new)
