Summary

• Remove t3code-orchestration.md, DESIGN.md, and the busybox log-forwarder sidecar from deploy/k8s/base/deployment.yaml.
• Fix the literal \n in two README spots (migrate code block, metrics table).
• Add MIT LICENSE.
• Add GitHub Actions CI: go vet, golangci-lint v2.14.0, go test -race against a postgres:16-alpine service, and a linux/amd64,linux/arm64 Docker build (no push).
• internal/pgtest: when PGTEST_DATABASE_URL is set, tests create and drop their own database on that server instead of starting testcontainers. CI uses this.
• Fix the 4 errcheck findings so lint passes.
• GET /v1/logs now returns 400 when tenant_id is missing or blank. The UI falls back to the demo tenant when the field is empty.
• Add cmd/loadtest and a README "Load test" section with measured results against a 1M-row seeded DB.

Load test (M1 Pro, Postgres 18.6, all on one machine)

• Highest load with no 503s: 600 req/s x 100 records = about 60k rows/sec persisted, p99 1.27 ms.
• Overload (50 senders, no rate limit): 84% of requests got 503 with Retry-After, the DB kept writing about 133k rows/sec, /healthz stayed 200, RSS 36-45 MB, and accepted == rows_written with lost = 0 after drain.

Testing

• go vet ./...: pass
• golangci-lint run ./...: 0 issues
• go test -race -count=1 ./...: pass, with testcontainers and with PGTEST_DATABASE_URL
• docker buildx build --platform linux/amd64,linux/arm64 -f deploy/docker/Dockerfile .: pass
• actionlint .github/workflows/ci.yml: no errors
• kubectl kustomize deploy/k8s/overlays/local: renders
