// parsing status histogram `kAttestationsFileParsingStatusUMA` are:

// manifest parsing is done by the component updater. However, for loading from
// APK assets, both manifest and attestations list parsing are done by the
// attestations class.
// 2. This histogram has more granular error conditions since there are more
// steps required to open files from APK assets.
