What a work trail actually needs to contain
Audit trails in AI systems are not optional. But most implementations capture what happened — not why it happened, who authorized it, or what data was used.
Most AI systems log what happened. A request came in. A model responded. A tool was called. A result was returned. These logs are useful for debugging. They are not audit trails. They are activity records, and activity records are not enough.
A real work trail — one that satisfies compliance requirements, supports human review, and enables meaningful accountability — needs to capture four things that most systems currently omit.
Authorization
Who or what triggered this action? Was it a human instruction, a scheduled trigger, or an upstream AI decision? What permissions were in scope at the time? Authorization is not just about who pressed the button — it is about the chain of decisions that led to the action, and whether each link in that chain was sanctioned.
Without authorization context, an audit trail cannot answer the most basic governance question: was this action allowed to happen?
Input context
What data was the decision based on? What documents, records, calculations, or API responses did the AI see before it acted? Without this, you can establish that a decision was made, but you cannot evaluate whether it was the right decision given what was known at the time.
This matters especially when decisions are challenged. A loan denial, a compliance flag, a routing decision — in each case, the relevant question is not just what the AI decided, but what it was working with. Input context is the evidence record.
Reasoning
For steps that involve AI judgment, what was the model reasoning? This does not mean storing raw chain-of-thought for every action. It means capturing the key factors that shaped the output, the alternatives that were considered, and the basis for the recommendation. This is what makes AI decisions reviewable by humans who were not present when the decision was made.
Reasoning records are particularly important in regulated industries. A compliance officer reviewing a flagged case needs to understand not just what the AI concluded, but why — what signals it weighted, what it deprioritized, what threshold it hit.
Human approval
When a human was involved — because a risk threshold was crossed, an exception occurred, or an approval gate required sign-off — what exactly was reviewed? What decision was made? By whom, and when? The human approval chain is often the most legally significant part of an AI operation, and it is the most commonly under-documented.
An approval record needs to capture the context that was presented to the reviewer, not just the outcome of their decision. If a loan officer approved a prequalification, the trail should show what summary they saw, what the AI recommended, and what they chose. That is the record that matters when the decision is audited six months later.
What this looks like in practice
A work trail that captures all four of these elements is not just a compliance artifact. It is the foundation of trust in AI labor. It is what lets you deploy AI workers in regulated industries, at scale, without every deployment being a liability.
Miji's work trail captures authorization, input context, AI reasoning, and human approval records for every action, in every operation run. It is not an afterthought bolted onto the system — it is built into the execution model from the start, because governance that is not built in does not survive contact with production.
Miji is the management layer for AI labor.
