A colleague says the notes are saved. The person picking up the work opens the shared folder and finds nothing.

The source incident for this lesson involved an AI agent and a machine-managed shared path, not a colleague. The same reader-side check is useful in ordinary handoffs because both cases fail in the same practical way: the person who needs the record cannot find it where the work is supposed to live.

The update may have sounded reassuring. It may even have been written with good intent. But the next person still has to reconstruct the decision from messages, memory, or another meeting. The handoff has not happened where the work needs it.

This becomes more likely when AI helps prepare reviews, summaries, or follow-up notes. An AI can produce a useful draft and report that it saved the result. That is not the same as proving that the agreed record exists in the place the next person will look.

## A handoff has two sides

The person or tool making the handoff can say, “I put it there.” The receiving side needs to be able to say, “I can open the right record, and it contains what I need.”

That second check is called a readback. It is simple: go to the one shared place that is supposed to hold the record, open the expected item, and confirm that it is the right one before relying on it.

A useful handoff names five things:

| Check | What the next person needs to know |
|---|---|
| Location | The one shared place that counts. |
| Record | The exact note, decision, or review they should find. |
| Contents | The facts, open questions, recommendation, or next step that should be there. |
| Owner | The person who decides whether the record is sufficient. |
| Stop rule | What happens if the record is missing, incomplete, duplicated, or in the wrong place. |

Without those details, people can mistake a friendly status update for completed work. The cost often appears later, when a decision is made from a partial note or someone spends time reconstructing a conversation that was supposed to be available.

## Where AI fits

AI can help prepare a review, sort recommendations, draft a shared note, and compare a record against a handoff checklist. It can also point out that a required field is missing or that two records appear to describe the same work. It should propose the record and destination for a person to confirm, not initiate a write or send an action to the shared destination on its own.

AI should not be the authority that decides a handoff is good enough. A readable record can still be incomplete, misleading, or based on weak evidence. The person responsible for the work needs to inspect the record, decide what it means, and choose whether the next action can proceed.

## The human decision

If the next person cannot read the agreed record, stop the handoff. Do not guess which version is right. Do not treat “saved” as proof. Find the authoritative place, restore or correct the record, and then let the owner decide whether it is ready to use.

## The lesson

A handoff is complete when the next person can find and read the right record where the work is supposed to live. A confident message is not a substitute for that proof.

The paired Build Log shows how a reported successful write to a shared work record can still fail the workflow, and why a separate receiving-side readback check is the gate that makes the handoff real.
