## TL;DR

If you own product quality at the org level, the expensive failures are rarely that the TypeScript was wrong. They are product experience failures that passed source review, looked shippable, and then hit brand, conversion, support load, or governance.

Diffraction is private MVP / design-partner ready UI review (product experience review) for UI-affecting GitHub PRs on web apps. Findings are aberrations: verified product experience failures with evidence. Tagline: See the full spectrum of every diff.

## Quotable definitions

Aberration (exec framing): a verified product-experience failure found while reviewing a running UI: the kind of miss that survives green checks and still costs brand trust, conversion, or cleanup after merge.

Source correctness ≠ product correctness: a clean diff and passing checks do not prove the product still works for a user. Executives feel that gap in incidents, churn, and war rooms, not in the PR comment thread.

## Problem for CTO / CEO / CPO

You already fund code review, CI, maybe pixel baselines, maybe a source-oriented PR bot. Those reduce some classes of risk. They do not systematically answer: did this UI-affecting change still leave a working product?

Visual bugs or broken layouts can show up as one kind of costly aberration. They are not the category. The category is product experience review of the running change: brand, conversion, and governance risk that source correctness alone does not catch.

Thesis: source correctness ≠ product correctness.

## What Diffraction gives executives

For design partners, Diffraction is built to surface aberrations with evidence before merge, so leadership risk is not only whether eng reviewed the diff, but whether someone experienced the product this PR would ship.

A named practice for the gap between green CI and product truth. Fewer post-merge surprises that become brand or conversion incidents. Governance-friendly evidence when something wrong almost shipped.

## How it fits executive workflow

You do not need every executive in every PR. You need the org to treat UI-affecting changes as product risk, not only code risk.

This is not a promise of zero incidents. It is a practice and a tool shape for the failure mode you already pay for after merge.
