Crate fakecloud_ce 

AWS Cost Explorer (ce) awsJson1.1 control plane for fakecloud.

The full 47-operation Cost Explorer Smithy model (com.amazonaws.costexplorer#AWSInsightsIndexService): anomaly monitors and subscriptions, cost category definitions and their resource associations, cost allocation tags (status + backfill history), resource tagging, commitment-purchase and savings-plans recommendation analyses, and the full cost/usage/reservation/savings-plans analytics surface.

Cost Explorer reports BILLING data. A fake account incurs no real AWS cost, so the honest, faithful state is a fresh account with zero recorded usage — the same framing fakecloud uses for CloudTrail (“no event-recording engine”). Concretely this splits into two halves:

• Fully real, account-partitioned, persisted CRUD for every stored resource: anomaly monitors/subscriptions, cost categories (+ versioning on update), cost-allocation-tag status + backfill requests, tags, anomaly feedback, and analysis/generation requests that settle to a terminal status so List/Get reflect them. Every Create is echoed by its Get/Describe, every Update persists, every Delete deletes.
• Structurally-valid zero/empty analytics for the reporting operations: the model’s exact output shape, correctly typed, with empty result series and zeroed-but-present required aggregate objects (ResultsByTime, forecasts, coverage, utilization, recommendations). This is the “no usage recorded” honest state, not a stub.

Model-derived input validation (@required, @length, @range, enum value sets) rejects malformed requests with a 4xx so negative variants get the right error.
