| EFS requires Lambda to run in a VPC. VPC Lambda can't reach AWS services (DynamoDB, SQS, Bedrock, S3) over the public internet — it needs either a NAT Gateway ($32/mo minimum, kills "zero cost at rest") or VPC endpoints. | |

| This is a Phase 0 infrastructure requirement — without endpoints, Lambda can mount EFS but can't reach DynamoDB for ACL checks. | |

The only remaining interface endpoint is Secrets Manager (~$7/mo/AZ, introduced in Phase 4). See [[Design/Async_Embedding_Pipeline]]. |
