The hosted API returned Cloudflare 525 for about four months after the Fly certificate failed to renew behind the proxy, and nothing alerted. Check the API, CORS preflight and origin cert expiry every 15 minutes. Co-Authored-By: Claude Opus 5.5 <noreply@anthropic.com>

Cloudflare serves a managed challenge to GitHub runners, so the proxied hostname can't be checked from Actions. Co-Authored-By: Claude Opus 5.5 <noreply@anthropic.com>

The hosted API (
policycheck.openattribution.org) returned Cloudflare 525 for about four months. The Fly certificate couldn't renew while the hostname was proxied. Nothing alerted. The DNS side is fixed (_fly-ownershipTXT plus the_acme-challengeCNAME). This PR adds the missing alerting.Runs every 15 minutes:
/analyzefor openattribution.org against the Fly origin. Fails on non-200 or on a result status other thansuccess. Retries cover cold starts. On failure it logs headers and body.Access-Control-Allow-Origin. Without it, the page shows "Failed to fetch".policycheck.openattribution.orgdirectly. Fails when fewer than 21 days are left. Fly renews at 30 days, so this catches a failed renewal about three weeks before it becomes a 525.Why the origin and not the proxied hostname: Cloudflare returns
403withcf-mitigated: challengeto GitHub runners, and a monitor can't solve a managed challenge. Once the proxied hostname stops challenging API traffic, add a check against it too.Alerting: a failed scheduled run emails whoever last changed the cron line. During an outage that's one email per run. That's noisy, and deliberately so.
