The Decision Portfolio
Every tool in this Level was practiced on Rohan, Priya, Meera — someone else's decision. This is the one exercise that isn't about them. Pick one real, currently-pending decision of your own — investing, trading, or otherwise — and run it through the seven fields below, before you know how it turns out.

Write your answers in a notebook, a phone note, or a doc — wherever you'll actually keep it. This page doesn't save anything; it's the template, not the record.
When you're making this decision — write it down before you know how it turns out.

What actually happened, once there's something to report.

Knowing only what you knew on the date above, would you make this same call again? Judge the reasoning, not the result.

This is the actual test of everything Level 8 taught: not whether you can name the Reversibility Filter or the Pre-Mortem Question on a quiz, but whether you reach for them on a decision that's actually yours. One completed entry is worth more than a perfect score on every question that came before it.
