A timeout does not prove the write failed.

The effect and its response can disagree.

What breaks

Write commits → response lost → blind retry → duplicate consequential effect.

Commit the write and then lose the response in the environment. Inspect whether the retry reconciles the stable request identity before changing state again. Retain attempted actions as well as the final record.

The counterexample matters as much as the failure.

A timeout before commit still needs a safe recovery path; always skipping the retry can leave the work incomplete.

Worked example · fictional records

Request R-104 · write committed · response lost

Evidence to inspect

The agent times out and cannot tell whether a record exists.

What would establish the fix

Read authoritative saved state using request identity before retrying. Check that only one intended record remains.

Counterexample

A retry that merely hides the duplicate in its answer still fails the saved-state check.

This example explains the check. It does not report a customer result or a completed production run.
