Where is shipment requested, and where is it handled? Driver get_code_map, orders / remove-zipkin. Condensed directory excerpt: config; controllers / OrdersController.java — creates orders and requests shipment. Now find the shipping handler. Driver get_code_map, shipping / master. Condensed directory excerpt: configuration; controllers / ShippingController.java — handles shipment requests and queue submission. Start with these two files: orders / OrdersController.java for checkout orchestration, then shipping / ShippingController.java for shipment handling. Paths abbreviate src/main/java/works/weave/socks with an ellipsis; sibling listings are excerpts. Calls and descriptions are grounded in captured Code Map evidence; cross-service handoff is corroborated separately in source. No automatic branch comparison or cross-codebase graph is implied.
