Dualmark conformance is **deterministic, scored, and CI-runnable**. Every page in your site can be verified against the AEO Spec v1.0 and assigned a 0-125 score.

## Two ways in

## What conformance gets you

- **Predictable AI agent behavior**. ChatGPT, Claude, and Perplexity all expect the same things. The spec captures them.
- **Catch regressions in CI**. `dualmark verify` returns an exit code -- wire it into GitHub Actions and never ship a broken markdown twin.
- **A score you can put on your site**. Standard or Advanced means you've done the work.
