Static Methods

public static string ApplyCandidate(CandidateSetting candidate, UnityEngine.Object targetAsset)

Calculates the target asset’s current SHA256 checksum, appends an entry to Library/DeviceFit/ChangeJournal.json, mutates the asset properties, and saves changes to disk. Returns the unique changeId.

public static bool RestoreChange(string changeId, out string errorMessage)

Validates the target file’s current SHA256 hash. If unchanged, restores pre-apply values. If an external user modification is detected, sets errorMessage and returns false to block blind overwrite.

public static List<ChangeJournalEntry> GetActiveEntries()

Returns all recorded journal entries currently in the applied state.
