### Grocery Retail Reference Architecture
End-to-end unified commerce reference architecture for grocery and food retailers operating across in-store, click & collect, and home delivery channels. Models the capability stack for high-frequency low-value transactions, fresh/perishable inventory, age verification, multi-buy promotions, and personalised loyalty programmes.


### RA-003
Unified Commerce reference architecture for specialty retail — knowledge-intensive, service-augmented retail formats where expert selling, product configuration, and post-purchase service are primary revenue and differentiation levers.


### Tier 2 Non-food Retail Reference Architecture
Vendor-neutral reference architecture for multichannel non-food and softline retailers with a material physical-store estate. POS is an intelligent engagement endpoint within a composable commerce ecosystem; authoritative customer, order, payment, inventory, pricing, and promotion responsibilities remain separated.
