Audit Trail
A mechanism for recording the operational history of a system, capturing timestamps, operator identity, and snapshots of actions performed. Audit trails serve as the basis for post-incident investigation, compliance review, and legal evidentiary purposes, providing a tamper-evident chronological record of system activities.

In the context of healthcare software, Traceability usually refers to the ability to fully record data provenance, change history, and the basis for decisions, and is often associated with audit trails.
A true audit trail needs to satisfy four properties: record the assembled set rather than the candidate set; immutable and addressable; tamper-evident (hashing the bytes); replayable.
In the compliance sense, audit trails need to satisfy hard requirements such as immutability (usually implemented through append-only storage or hash chains), complete context (recording who triggered which operation at what time, in what identity, and based on what input), and traceability (the ability to restore the data state before and after an operation).
For a law firm, knowing who approved what and when is just as important as the content itself (the compliance chain of the audit trail is a core requirement).
Financial institutions introducing large language models must first prove three things: a complete audit trail, PII desensitization before data enters the model, and access controls divided by team.
