[Programcode]

Moves DebateOwl to https://debateowl.com and retires debate.pi-stack.org.

Changes

• Canonical origin: src/config/site.json origin is now https://debateowl.com, and the brand is DebateOwl (titles no longer end "| DebateOwl by Pi-Stack"). The SEO pages and llms.txt were regenerated with scripts/generate_seo_content.py. index.html og/twitter/author, humans.txt, robots.txt sitemap, embed canonical, README, AGENTS, docs, e2e/tests and playwright.production.config.ts are updated too. Footer copyright now reads "© 2026 Pi-Stack.", and the JSON-LD organization stays Pi-Stack.
• Old host 301: the first vercel.json redirect sends every path on debate.pi-stack.org to https://debateowl.com/:path with a 301, and Vercel appends the query. /sw.js is the only exception. check-site.mjs ignores host-scoped rules.
• Service worker: on debate.pi-stack.org the new sw.js skips precaching, clears every cache, unregisters, and reloads its tabs. The tabs then follow the 301. Fetch and message handlers do nothing there. Tested with Playwright: today's prod worker is installed on the old host, then the host is flipped to the new behaviour. Deep links land on debateowl.com with the query intact, and the old origin ends up with 0 registrations and 0 caches.
• Edge functions: CORS (_shared/cors.ts), checkout callbacks and workspace-invites now allow https://debateowl.com, and it is the fallback origin. https://debate.pi-stack.org stays allowed.

Left on purpose

• The move-notice copy ("DebateLab is becoming DebateOwl"), package and storage keys, env names and the repo name.
• scripts/gsc_submit.py, which is tied to the Search Console properties.
• The admin demo-account email domain, which is an identifier.
• The debatelab-* URL slugs.

Before merging

The prod edge functions must be redeployed with the new CORS first. Today they answer Origin: https://debateowl.com with Access-Control-Allow-Origin: https://debate.pi-stack.org, so once the 301 is live every AI, checkout and announcement call from debateowl.com fails.

npm run verify passes locally.
