Built for recovery

Nothing gets flattened. Nothing gets guessed.

Lossless originals

The original bytes are stored in the master, so line endings, quotes, column order, and notes survive.

Future-site recognition

Current sites use structural fingerprints; new Mel's CSV Contract sites register automatically without filename guesses.

Future-safe quarantine

An unfamiliar future CSV is preserved and flagged instead of rejected or silently misfiled.

No hidden background state

The interface always loads fresh. Reports stay only in the current page until you save them.

This removes the reports from this page only. Your original files and anything already downloaded stay untouched.
