# Withdraw unsafe evidence and follow up affected recipients

Hold results or dependencies with a recorded reason and retain the original engineering history.

Review edition: 25 October 2026

Roles: reviewer, supervisor

Use withdrawal when an engineering basis or accepted result should no longer be relied on for current use. Establish the affected identity and scope first. Withholding a result changes its current eligibility while preserving the accepted calculation and the evidence of earlier handovers.

## Choose the correct withdrawal

Reviewers can withdraw a component or reference-table dependency and a family release. Reviewers and Supervisors can withdraw an individual result. Use the control matching the actual concern rather than editing an unrelated draft to create the appearance of a correction.

Give the engineering reason and preserve the source evidence. A dependency issue can affect several results, while a unit-specific source error may require a narrower result decision. Check the affected records and current eligibility reasons after the action.

## Review historical recipients

Open Receiver and withdrawal follow-up and Engineering impact tasks. Identify each exact pack, receiver and earlier observed outcome. Record the communication and receiver evidence through the available follow-up actions. A task being created does not establish that the receiver was reached. Another Supervisor must review reported handover evidence with Independently review handover evidence; its reporter cannot approve it.

Separate an intended request from an observed response. A recipient may have only downloaded a pack, acknowledged it or reported a different state. Use the actual evidence and retain an unresolved task when confirmation is still missing. Receiver confirmed work stopped and Engineering disposition recorded put the follow-up into pending review. A different Supervisor uses Independently review this disposition to close it.

## Prepare the next safe evaluation

If the source facts need correction, the Supervisor uses an amendment or remake and a fresh evaluation. If the family model needs correction, the Author prepares it with independent cases and a different Reviewer approves and activates the resulting release.

Do not overwrite old accepted values or remove the original pack merely to make the history agree with today's position. Those records may be needed to understand who received which engineering basis.

Use [Amend or remake](/manuals/factoryspec/amend-or-remake) and [Review a candidate](/manuals/factoryspec/candidate-review) for subsequent work. Read the evaluation-only notice throughout: withdrawal and follow-up do not claim that physical manufacture occurred or was recalled.
