Each FreshCart service gets the architecture its own requirements call for — not one pattern copy-pasted twelve times. Ordering earns DDD + a saga because it holds the richest invariants; Basket gets Redis + outbox because it's transient, high-throughput state; Payment gets event sourcing because compliance demands an immutable audit trail. That's a deliberate per-service decision, documented and enforced in the repo's own engineering standards.
- 🧪 Up next: a self-improving personal agent runtime — exploring the Hermes Agent / OpenClaw class of self-improving, learning-loop agent frameworks as a base to build on.
