PHASE-7 CALIBRATION

Q2 2026 · BLOCKTANK B.V.

Roger predicted the quarter before the accountant filed. The prediction was frozen. This is the measurement of the gap — the control the whole Tax Mode build was designed around.

WHY THE HEADLINE LIES

Each bar is a place where Roger's method and Erik's method genuinely disagree. They very nearly cancel. That near-cancellation is the whole reason a headline match proves nothing.

PRE-REGISTERED HYPOTHESES

Written down on 23 Jul, before Erik filed — so the scoring can't be retrofitted.

DISCOVERED DIVERGENCES

Not predicted. Surfaced by the diff itself — honestly labelled as such.

PER-CATEGORY LEDGER

Claimable VAT per category. Roger's reverse-charged lines net to €0 against the refund, which is how they're compared here.

The point of the exercise: turn the accountant's method into Roger's rules before Q3.
