Best Evergreen Notes for Data Scientists

What Evergreen Notes actually asks of you

Notes are rewritten, not accumulated — a note that hasn't been touched in a year is a question, not an asset.

When a new note contradicts or sharpens an old one, you edit the old one in place and leave a link to what changed. The measure of the system is the quality of a note after a year, not the count after a week.

How data scientists put it to work

1. 1

   An experiment log with its hypothesis

   Every experiment captured with what it hypothesized and what it actually found — including the nulls. The notebook of failed directions is the most valuable file in the project.

2. 2

   The model decision trail

   Why a feature was dropped, why a threshold moved — captured where the analysis happened. Six months later, when someone asks why the model ignores that variable, the answer is linked, not remembered.

3. 3

   Findings that resurface

   When a new question arrives, old analyses that touch it surface on their own. Half of data science is rediscovering that you already answered a version of this question last quarter.

The capture habit, the linking, and the retrieval are the parts tentus automates — evergreen notes without the daily upkeep.
