Audit trail
An audit trail is a record of who changed what and when, kept so that a past state of a system can be reconstructed and investigated. Syndik8 keeps audit-trail data on two things in particular: usage logs and the financial ledger.
Editing a saved usage log stamps edited_by and edited_at on the row. The log history on the asset’s Usage screen shows that an edit happened; viewers know the log was changed.
The financial ledger is append-only. A transaction is never edited in place — corrections are made by posting a reversal, leaving both the original and the reversal visible forever.
