Launch-polish sprint: audit, demo, status, badges

A cluster of launch-polish items shipped together: - **Demo organization on first signup** — every new account lands in a pre-seeded "Demo · CheckUpstream" workspace alongside their real one, with two mock projects, real tracked services, and a guided four-step tour. - **Per-service embeddable badge** — `<script src="https://checkupstream.com/embed/badge.js?service=stripe"></script>` drops a live reliability pill anywhere. - **Platform status page** — /platform-status publishes CheckUpstream's own subsystem health, server-rendered against the same /api/health body external uptime monitors consume. - **Security + privacy hardening** — strict Content-Security-Policy, rate-limited discovery endpoints, `SECURITY.md`, `DATA_COLLECTION.md` engineer-facing technical reference linked from the privacy policy. - **k6 load-test suite** — nightly synthetic tripwire on MCP transport, ingest, and /api/health with SLO gates baked into the CI job. - **Continuous polling on every wired integration** — Vercel, Grafana, Datadog, Fly.io, and New Relic signals now flow into the correlator alongside status-page + community sources. - **Registry mining (deps.dev + GitHub velocity)** — LLM prompts and the `audit_dependencies` MCP tool now surface "is this library still alive?" alongside known CVEs.

CheckUpstream public launch

CheckUpstream is now publicly available. Monitor the health of every upstream dependency your software relies on — package registries, cloud APIs, DNS providers, CDNs, and more. Start with the free plan, connect your repos, and get real-time alerts when something breaks upstream.

Go SDK now available

The Go SDK joins TypeScript, Python, PHP, Ruby, Rust, Java, and .NET. Drop-in middleware for net/http, Gin, Echo, and Fiber tracks upstream API latency and error rates from your production traffic. Install with go get github.com/checkupstream/sdk-go and start reporting in under five minutes.

Code-aware import analyzer

CheckUpstream now analyzes your source code to discover which upstream services you actually use. Instead of relying on manual configuration, the import analyzer walks your dependency graph and maps imports to known cloud services. Zero config. Just push code and we figure out what you depend on.
