When you upload a new lab file, Piper reads its header row and computes a fingerprint, then compares it against stored headerFingerprint values across all ImportMappingProfiles for your tenant. A match means Piper can automatically suggest or apply the correct profile without manual selection. This fingerprint-based matching saves time during routine imports from recurring labs and reduces the risk of a compliance user accidentally applying the wrong columnMapping to a different lab's report format.

Import Mapping Profile Header Fingerprint
The `headerFingerprint` on an ImportMappingProfile is a computed signature of the column headers in the lab report format the profile covers.
