Walkthrough

The aws-bedrock provider discount was changed from "0.2" to "0.1" across 14 Claude model entries in packages/models/src/models/anthropic.ts. The Bedrock Claude cache-write test in apps/gateway/src/lib/costs.spec.ts was updated to derive the discount from the models registry and assert against that dynamic value.

Changes

AWS Bedrock Discount Rate Adjustment

Layer / File(s)	Summary
Discount rate updates across Claude models packages/models/src/models/anthropic.ts	The discount field for aws-bedrock provider entries is reduced from "0.2" to "0.1" across 14 Claude model definitions (claude-3-7-sonnet, claude-3-5-haiku variants, claude-sonnet-4 variants, claude-haiku-4-5 variants, and claude-opus-4 variants).
Bedrock Claude cost test reads registry discount apps/gateway/src/lib/costs.spec.ts	The AWS Bedrock Claude cache-write test now reads the aws-bedrock provider discount from the models registry, converts it to a number to compute the discount multiplier, and asserts result.discount against that derived value instead of a hardcoded multiplier.
