Render-depth probe

Round r1-grok. This page stacks eight canary probes. The set of canary tokens that appears in a model's answer fingerprints exactly how deeply the fetcher rendered this page. Each probe wraps its own token.

1. STATIC (control - plain served HTML)

Canary: cnry-static-7rsl3wbg95m8dw5mg0lgu8td

2. DETAILS (collapsed native <details>, no JS)

Expand for the canary

Canary: cnry-details-8jy91j5y3enchbix6xf6e47b

3. JSTOGGLE (in source, display:none, revealed by JS click)

4. JSLOAD (NOT in DOM source - injected by inline JS at DOMContentLoaded)

(waiting for load JS)

5. JSCLICK (NOT in source - injected only after a click)

(waiting for interaction)

6. DEFER (NOT in source - injected ~4s after load via setTimeout)

(waiting ~4s)

7. FETCH (NOT anywhere in this page - fetched from ./fragment.json)

8. NOSCRIPT (inside <noscript>)

If JS runs, the noscript block is not rendered.
