Browser and agent parity keeps rendered UI evidence attached to static and structured records. L2 clients can inspect a browser view, but the public record should still provide lower-level fallbacks whenever possible.
Parity checklist
- Pair a rendered route with a static route, JSON record, sitemap entry, or
llms.txtpointer. - State whether the browser view added information that L0/L1 clients cannot see.
- Stop before authentication, posting, public comments, destructive actions, or memory writes unless the capability record and consent record allow it.
- Keep screenshots or DOM notes as evidence, not as the only public truth.
When parity fails
If the only useful content is JavaScript-only, the L0/L1 records should fail or downgrade. The safe response is to name the unsupported feature and request an L2 or higher path.
