How we built saga rollbacks for Cloudflare Workflows

This blog post introduces saga rollbacks for Cloudflare Workflows, letting developers attach idempotent compensation handlers to individual step.do() calls so multi-step processes can be unwound predictably when a workflow fails. It explains API choices (options object vs. fluent/builder styles), execution semantics (reverse step-start ordering, eligibility rules, rollback lifecycle events), recovery via replay to rebuild rollback stubs, and configuration for retries/timeouts, illustrated with fund-transfer examples.
