Prepare website for Cloudflare Workers Static Assets - #144
The live /learn URL redirects into an nginx directory 403. This prepares all nine Astro pages for Workers Static Assets, with both slash variants served directly through generated 200 rewrites and no Worker script. DNS and Hetzner are untouched.
Includes deploy/PR-version CI, cache/security headers, and manual setup, custom-domain, alias redirect, cutover and rollback instructions in website/DEPLOY.md. Fork PRs only build; trusted PRs upload previews when both secrets exist, otherwise emit an explicit Actions warning. Production deploy remains strict.
Proof: Astro build, SEO check (9 pages/9 sitemap URLs), Wrangler deploy dry run, and curl/body checks against npx wrangler dev passed.
No repository Actions secrets are currently listed. CLOUDFLARE_API_TOKEN and CLOUDFLARE_ACCOUNT_ID must be added by an owner as protected environment secrets; neither was created.
No authenticated Cloudflare deployment/version upload, workers.dev URL, custom domains/TLS, redirect rules or public cutover was tested. Before cutover, also verify that an authenticated redeploy preserves dashboard-attached custom domains. No DNS/server changes made.
Current build inlines CSS and emits no /_astro assets; immutable header rule is configured for future hashed assets.
npm reports 10 dependency vulnerabilities (9 high, 1 critical); dependency remediation is outside this hosting migration.
Python CI-fix verification: Ruff and strict mypy pass; pytest reports 22 passed, 3 daemon-dependent tests skipped locally. Rust checks ran in GitHub Actions.
CI follow-up: initial preview upload failed because both secrets are absent. Added and shell-tested the explicit missing-secret warning/skip for PRs. The separate Python SDK job initially reported Ruff lint errors inherited from main; 8da2fe3 fixes them with import/annotation/export-order cleanup.
Independent Sol review found an overwritten ignore file; original ignores were restored and .wrangler/ appended, verified with git check-ignore.
Reviewed with sol-loop: 2 rounds with gpt-6.1-sol on medium effort. Sol verdict: approved on 71ab849 (before the small missing-secret CI follow-up).
Created with gpt-6.1-sol in T3 Code (Codex harness).
Latest follow-up (2236b0a): both scripts normalize Windows filenames to URL slashes; build, SEO and full local route checks passed again. Native Windows execution was not available. Both required checks passed. Demo smoke passed on rerun after a Postgres seed-connection failure. Python SDK lint failures were subsequently fixed in 8da2fe3. Human approval is required by branch protection.
CI fix 8da2fe3: independent gpt-6.1-sol review approved the Python-only follow-up. Local Ruff, strict mypy and pytest pass (22 passed, 3 skipped). Current-head GitHub CI is pending.
Summary by CodeRabbit
New Features
Added automated website builds and production deployments, with preview uploads for eligible pull requests.
The website now supports static hosting with route handling, improved security and caching headers, and SEO checks.
Documentation
Updated deployment guidance for Cloudflare hosting, previews, cutover, and rollback.
Chores
Updated Python SDK type annotations; behavior remains unchanged.
Security follow-up db89bb7: deployment now uses protected website-production/website-preview environments. Configure main-only production, owner-approved previews, and separate preview-account credentials before adding environment secrets; do not add deployment tokens as repository/organization secrets. See updated DEPLOY.md. Protection enforcement and authenticated uploads remain owner setup and are not verified.

Walkthrough
The website now builds as a static site for Cloudflare Workers Static Assets. A GitHub Actions workflow builds and checks the site, deploys pushes, and uploads previews for eligible pull requests. The Python SDK updates type annotation syntax without changing the described runtime behavior.
Astro is configured for static output. The build generates route rewrites, and Wrangler configuration sets the asset directory and handling options. Header rules and a route-checking script are added.
Build and Cloudflare deployment .github/workflows/deploy-website.yml
The workflow builds the website and runs its SEO check. Pushes deploy to Cloudflare. Eligible same-repository pull requests upload preview versions; if credentials are missing, the preview step warns and exits successfully.
Deployment and cutover documentation website/DEPLOY.md, website/README.md
The deployment guide describes setup, route and cache expectations, domain configuration, verification, and rollback. The README adds learn routes and points to the guide.

The title "Prepare website for Cloudflare Workers Static Assets" matches the main change. The PR moves the Astro site to static output, adds Wrangler config, static route rewrites, deploy CI, and DEPLOY.md documentation for Cloudflare Workers Static Assets. The Python SDK type-hint edits are minor side changes that the title does not mention, which is acceptable because the title does not need to cover every detail.

Deferring the CodeRabbit suggestion to run Wrangler route checks in CI: all nine pages, slash variants, HTML URLs, feeds and missing paths were already checked against local Wrangler, with the full curl output in this PR. Adding server lifecycle management to CI is optional follow-up rather than a fix for a failing route. The reusable scripts/check-routes.mjs remains available for pre-cutover checks.
The latest Python SDK failure is still the same 24 Ruff errors in SDK files unchanged by this PR. The website build/SEO and preview-secret handling are separate from that failure.

🔵 Needs a closer look
Windows backslashes in recursive filenames produce invalid redirect rules and route-check URLs, so both scripts need forward-slash normalization.
No open issues 🎉

In code that hasn't changed since last review
Normalize Windows paths when generating redirect rules
website/scripts/static-routes.mjs:5
On Windows, recursive readdirSync returns nested filenames with backslashes, so the generated _redirects rules do not match the slash-separated article URLs. Normalize filenames to forward slashes before generating the rules. Apply the same normalization in website/scripts/check-routes.mjs:7, where these filenames otherwise produce incorrect request URLs.
Fixed the Windows-path observation in 2236b0a: both scripts normalize recursive filenames to forward slashes before generating URLs. Astro build, all nine SEO checks, a synthetic backslash normalization assertion, and the full local Wrangler route/body/status checks passed again. Native Windows execution was not available.

Owner verification is needed for authenticated Cloudflare deployments, PR version uploads, custom-domain/TLS behavior, and rollback before public cutover, as local Wrangler checks do not cover these operations.

Owner validation is still needed for authenticated Cloudflare deployments and PR version uploads, including custom-domain/TLS behavior and domain preservation across redeploys before production cutover.
Fixed the Windows null-device issue in 6483ec5: the route checker now uses node:os devNull instead of hard-coded /dev/null. The full local Wrangler route/body/status/zero-redirect check passed again, including both missing-path 404 checks. Native Windows execution remains unverified.

Check the HTML response type for each route.
If a server returns the correct body as text/plain, this checker still passes, but browsers can display the markup instead of rendering it. Check that each HTML response has a text/html Content-Type, allowing parameters such as charset.

Compare the RSS response with the built feed.
An empty or unrelated /rss.xml response passes the route check if it returns HTTP 200 without redirects. Compare its body with the built feed so the check can detect an unusable response.

Deferring the two CodeRabbit test-expansion nits. The local Wrangler response for /learn was directly verified as text/html; all built HTML bodies and status/redirect behavior were checked. No incorrect MIME type or feed response has been reported. RSS content equality and additional MIME assertions can be added later if needed; this migration keeps the requested route checks focused. Current-head Python, website build/SEO, and deployment-workflow checks pass.

Configure main-only production, owner-approved previews, and separate preview-account credentials before adding environment secrets; do not add deployment tokens as repository/organization secrets. See updated DEPLOY.md. Protection enforcement and authenticated uploads remain owner setup and are not verified.
