The Decisions Behind It.
What made this hard?
In ESG verification the provenance of the data is the product. If you cannot trace where a number came from, the whole report is worth nothing.
How was the system structured?
Every metric is stored with its source, timestamp, and verification status, kept separate from the aggregate value. Reports are derived views rather than stored numbers, so correcting the source data updates the reports automatically.
What does the codebase look like now?
Verification workflow states are modelled explicitly instead of as boolean flags, so partially verified data is never misrepresented as verified. Methodology assumptions are documented alongside the code that implements them.
