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.

Known-site recognition

Stock Check and Delivery Intake use separate structural fingerprints, not 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.
