Single stateless Go process that consumes CT logs via embedded (patched) CertSpotter internals, classifies cloud/database/storage DNS identifiers in-process with a zero-allocation classifier, enriches via round-robin DNS resolvers with CNAME following, and batch-writes useful findings to PostgreSQL. - third_party/certspotter: 2-hunk IdentifierSink patch, no stdout/JSON/files - internal/classify: AWS/Azure/GCP/Firebase/Cloudflare R2/DigitalOcean/Supabase/OCI - internal/dns: sharded bounded TTL cache, multi-resolver load balancing + failover - internal/pipeline: bounded queues, dedup, direct-priority load shedding - internal/store: pgx batch writer, Postgres CT checkpoints (no cert contents) - internal/probe: optional non-destructive reachability checks (off by default) - Docker: distroless non-root, read-only rootfs, no app volume, resource limits - tests enforce 0 allocs/op on the classifier and sink hot path
