Two ledgers keep VideoCore honest. The Learning Ledger logs a hypothesis before the test and moves it to testing and concluded. The Forecasting Engine projects growth, revenue and milestones from your own numbers and says what moves the needle.
Log a hypothesis before you test it: what you are testing, how, the project, the topic cluster. It sits in Hypothesis until the test runs, then Testing, then Concluded with the result. Four logged here, none concluded yet, which the counts say plainly.

The channel snapshot is filled from your Blueprint and connection: subscribers, upload frequency, average views. Generate Forecast projects subscribers and views, revenue and milestone dates with ranges and the assumptions stated. Test it on your channel checks a claim like series beat one-offs against your own videos.

A forecast or a claim written down before the outcome can be scored right or wrong afterwards; one written after it cannot, which is why both ledgers date the entry first and the result second.
