Bilko CSP Cleanup — MC #10440 (next.config.js basicconsulting.no to alai.no migration)

Bilko CSP Cleanup — MC #10440 (next.config.js basicconsulting.no → alai.no migration)

Documentation for MC #10440 — follow-up to MC #10428 (Gemini code-review) to clean up stale/misleading CSP entries and allowedDevOrigins in apps/web/next.config.js after the basicconsulting.no → alai.no domain migration.

Context

During a Gemini-driven code review of Bilko's Next.js configuration (MC #10428), several stale domain entries were flagged in the development CSP (Content Security Policy) and allowedDevOrigins array. These entries pointed to the old basicconsulting.no domain, which has been retired in favor of alai.no.

Changes Applied

File: apps/web/next.config.js

Removed Dead Hosts (basicconsulting.no)

• bilko-demo.basicconsulting.no — curl verification: TLS handshake completes, no HTTP response (CNAMEs to the same dead GCP Cloud Run family MC #104221 already confirmed dead)
• bilko-demo-api.basicconsulting.no — curl verification: HTTP 502 (Cloudflare proxy up, origin dead)
• *.basicconsulting.no wildcard — removed from both connect-src and allowedDevOrigins

Scoped Wildcard to Explicit Host

The allowedDevOrigins array contained a broad *.alai.no wildcard. Narrowed to the single explicit host actually used:

• Before: *.alai.no
• After: bilko-demo-api.alai.no

Corrected Misleading Comment

A comment incorrectly described the alai.no hosts as "dev tunnels" when they actually point to a remote Cloud Run demo environment. Corrected for accuracy.

Production CSP Untouched

The production CSP branch was left unchanged. All modifications were scoped to the development environment only.

Audited (Not Modified)

Additional vestigial CSP entries were identified but not removed — outside this task's scope:

• script-src / style-src — Google Fonts CDN entries (app self-hosts fonts via next/font/google, per MC #100227)
• script-src — Sentry CDN entry (app uses the npm SDK, not the CDN loader)
• img-src — r2.bilko.io confirmed as a near-term placeholder for an OG image (app/page.tsx comment)

Flagged as future cleanup candidates.

Validation

• curl verification: all dead hosts independently confirmed (basicconsulting.no timeout/502; bilko-demo-api.alai.no SSL error — see below)
• grep verification: no other live alai.no subdomain needed by the dev server
• Build sanity: npx turbo run lint --filter=@bilko/web and npx turbo run build --filter=@bilko/web both green
• Independent re-validation: Proveo independently re-ran all checks (curl, grep, build) — PASS on all 5 acceptance criteria

Known Open Issue — MC #104570

Important: during this work, bilko-demo-api.alai.no itself was found dead (SSL_ERROR_SYSCALL; DNS resolves to an orphaned Google-hosted IP, 142.251.38.115).

This contradicts MC #104221 (2026-06-28, 3 days prior), which reported this host as "LIVE 200". MC #104570 (H priority, opened 2026-07-01) tracks investigating whether the Bilko live demo is currently broken.

The CSP entry referencing bilko-demo-api.alai.no was correctly left in place (CodeCraft/Proveo decision) — removing a currently-referenced entry without confirming permanent death risks breaking an expected path. Do not treat this host as confirmed-live until MC #104570 resolves.

Related Tasks

• MC #10428 — Gemini code-review that flagged these concerns
• MC #104221 — Prior CSP work (2026-06-28), reported bilko-demo-api.alai.no as "LIVE"
• MC #104570 — Follow-up investigation into bilko-demo-api.alai.no death (H priority, opened 2026-07-01)

Deployment

No separate deployment required — config-only change, lands via normal PR merge to azdo/main.
