METHOD

What it calculates.

First row defines the schema. Subsequent rows are checked for width, exact duplicates and empty cells; finite numeric cells determine per-column numeric ranges.

LIMITS

What the evidence means.

Does not validate real-world truth, remove sensitive data or connect to Snowflake. Upload only authorized datasets.

The funding planner does not transfer tokens or route rewards. Deploying this repository does not imply company endorsement or investment value.
