Finish legacy-site cutover: merge PR #1583, then point LEGACY_ORIGIN back at Render

[kgilpin]

appmap.io now routes to the worker (cutover 2026-08-26), and the worker proxies docs/blog 404s to LEGACY_ORIGIN, currently pinned in wrangler.jsonc to the Cloudflare Pages branch alias for the PR #1583 branch:
https://feat-migrate-to-new-marketin.applandinc-github-io.pages.dev

That alias is a temporary origin — branch-alias edge caching can serve stale content for up to ~an hour after a push, and it tracks an unmerged branch.

Steps

1. Merge getappmap/applandinc.github.io PR #1583 (the old-site page removals held for cutover).
2. Wait for Render (https://appland-com.onrender.com) to rebuild from master and spot-check a docs page and a blog post there.
3. Delete the LEGACY_ORIGIN var from wrangler.jsonc (the code falls back to the Render origin — DEFAULT_LEGACY_ORIGIN in src/server.ts) and push; CI deploys.
4. Verify through the domain: https://appmap.io/docs/appmap-docs.html and a blog post return 200; https://appmap.io/sitemap-docs.xml still lists the docs URLs.

Note: Render stays load-bearing indefinitely as the proxy origin for docs/blog/videos — do not decommission it.

See CUTOVER.md § Phase 2 and the wrangler.jsonc comment for context.

Done:

• PR getappmap/applandinc.github.io#1583 merged (2026-09-04, admin merge by Kevin)
• Render rebuilt master: removed pages 404 there, docs/blog 200
• LEGACY_ORIGIN var deleted from wrangler.jsonc (commit 6d6b783); worker now proxies to the Render default origin
• Verified through the domain: /docs, /blog, a dated blog post, /company/brand-assets, and /sitemap-docs.xml all serve correctly

Render (appland-com.onrender.com) remains the permanent proxy origin for docs/blog/videos — do not decommission.
