Why

The new app catalog, four SEO guides, support Play CTAs, and analytics were merged into GitHub but the apex appdevelopsk.com is served from a separate VPS, not GitHub main/Pages. Source-only QA passing can mask a broken acquisition launch for days. An actual live page check was required manually in issue #8.

Changes

• Add read-only scheduled GitHub Actions workflow at approximately 09:40 JST to run the existing scripts/check_app_discovery_live.sh against the real production HTTPS origin, including homepage, catalog search, four guides, two enhanced support CTAs, unavailable Face Battle alternatives, robots and sitemap. Github's scheduler may delay execution.
• Fail visibly if deployment is missing/stale and provide exact manual safe dry-run/rsync/live-validation instructions in workflow summary. Never deploy to VPS or modify Store metadata automatically.
• Add regression checks for schedule, read-only privileges, and the verification command; extend existing app-discovery CI to cover the workflow file. Update deployment runbook.

Release boundary: until an operator runs the already-provided VPS deployment, this new production smoke may intentionally fail. This does not prove installs; analyze post-deploy GA4->Play acquisitions with mature cohorts. No duplicate scheduled ChatGPT audit task is created.
