AWS accounts and resources

Three accounts are in play. Using the wrong profile is a common source of “the resource doesn’t exist”.

Profile	Account	Owns
default	394922924679	calculatecost2, dev + prod storefronts, most legacy APIs
villa-ecommerce	017176210331	villacoupon3
villaai	914499832220	AI/experimental sites, villamarket.ai, this knowledge base

Credentials are already configured; set AWS_PROFILE rather than exporting keys.

Cross-account invoke

calculatecost2 (default) invokes the VillaCoupon3 checker (villa-ecommerce) directly by ARN. It needs a resource policy statement on the villa-ecommerce side:

AWS_PROFILE=villa-ecommerce aws lambda get-policy \
  --function-name villacoupon3-checker-dev --region ap-southeast-1

Expected statement ids include AllowCalculateCost3DevCrossAccountInvoke and one for the CI user. Removing them makes calculatecost2 fall back to the legacy checker, which returns no discounts without raising an error.
