Problem

A growth team is launching a new analytics platform that needs to ingest from all four shapes at once: a Postgres orders database (pull), a Kafka clickstream topic (push), an SFTP partner directory (file drop), and the Stripe API (API). Every source must land in a single Iceberg raw zone, each with the right resume state and the right defensive checks. Assemble the multi-source ingestion: incremental pull with bookmark on Postgres, write-first-commit-after Kafka consumer with webhook buffer, manifest plus validation plus processed-prefix on SFTP, and cursor-based paginated API ingest with rate limiter, OAuth refresh, and 429/5xx backoff.
