First-party operational work

Repairing a Cloudflare Worker canonical-URL redirect loop

A production site stopped serving pages because asset requests for .html files bounced back to their clean canonical paths.

Scope

A production issue in Demonic Binary's own Next.js static export and Cloudflare Worker deployment.

Testing and validation

Built the Next.js static export and ran the existing automated tests.
Exercised /, /services, /contact, /robots.txt, /sitemap.xml and an unknown path against a local Worker.
Checked successful pages returned HTTP 200 without loops, unknown paths returned HTTP 404, and the www hostname redirected to the apex.
Repeated those checks against the public hostname following deployment.

SiteGuard Monitor: service-health and alerting demonstrator

We implemented Python/SQLite probes, durable health observations and a status view, then exercised the alert states with synthetic failure sequences.

Reproduce an original lab

The API authorization lab has public Node.js, SwiftUI and Kotlin sources and synthetic test fixtures. Its reproducible implementation is separate from anonymized experience-based work.
