# validation

## When to use

Use when the task matches: validation, product acceptance, preview review.

## Purpose

Record Product acceptance or rejection of demonstrated behavior.

## Inputs

- Runnable POC
- Acceptance criteria
- UX flow

## Process

1. Walk acceptance criteria with Product using the POC.
2. Record who reviewed which revision and when.
3. Separate Product validation from engineering verification.
4. Send rejected behavior back to definition or UX as needed.

## Outputs

- Validation record
- Accepted criteria
- Rejected feedback
- Revision requests

## Verification

- Confirm each output exists and is reviewable.
- Keep Product validation and engineering verification distinct.
- Do not claim completion without evidence.

## Restrictions

- Do not treat PREVIEW_READY as production release.
- Do not skip Product review by substituting automated tests.
- Do not claim acceptance without named reviewer evidence.
