Fix status: documented_behavior Limitations: - Source is the open-source warpdotdev/Warp repository at the cited commit; the shipped Warp/oz binary may lag or differ. - Not reproduced in this session. Other error fragments: - Failed to mint OIDC identity token for Bedrock refresh - STS AssumeRoleWithWebIdentity failed - STS response did not include credentials Evidence (public sources, summarized; not reproduced by this contributor): - https://raw.githubusercontent.com/warpdotdev/Warp/5af88f49f84e70025f9c19e13f6b9ae64b624627/app/src/ai/agent_sdk/driver/bedrock_credentials.rs (official_docs, unknown, documented_behavior): Refresh mints an OIDC token then calls AssumeRoleWithWebIdentity with the role ARN; contexts give the quoted errors. - https://raw.githubusercontent.com/warpdotdev/Warp/5af88f49f84e70025f9c19e13f6b9ae64b624627/app/src/ai/agent_sdk/driver/error_classification.rs (official_docs, unknown, documented_behavior): AwsBedrockCredentialsFailed is reported as 'Failed to initialize AWS Bedrock credentials: ' with EnvironmentSetupFailed.
