This drill helps Communication Protocol learners verify deployment outcomes with evidence instead of assuming that a green pipeline automatically means users received the correct content.

What students can learn

• Why GET requests and response-body inspection often prove more than a simple HEAD check.
• How browser-like headers change what edge platforms return for static pages.
• Why XML-based assets such as SVG diagrams should be validated as structured documents after deployment.

Included practice asset

Use the paired edge verification sequence map to walk through each verification layer from workflow completion to final user-visible proof.

Recommended classroom use

1. Start with a successful CI run and ask students which extra evidence is still needed before calling the release complete.
2. Run the verification commands from the downloadable drill sheet and compare weak versus strong proofs.
3. Finish with a short retro on which protocol signal failed first in each scenario.

Why this is useful here

The site already uses GitHub Actions, Cloudflare Pages, and a Worker endpoint. This drill turns that real delivery path into a protocol-reading exercise that strengthens the currently lightest pillar with a practical, low-risk teaching asset.
