outline

This is an outline, not a result.
Nothing here has been built. It states what the block is for, what it has to produce and what would make it a failure, so that the claim can be checked against the result later. Written 2026-09-01, and it will change.

Why this block exists

Scheduled here because it comes needs a live service with real traffic to shadow, which has existed since B11. Almost nobody builds a portfolio for this because greenfield demos are easier and look better.

What it has to produce

Replace something that already runs, without breaking it. Start the shadow comparison that produces your strongest differentiating artifact.
