AWS Cognito Identity client bundled, STS client rewritten

Not switched on
Useful1 Signal3
AWS Bedrock

An AWS Cognito Identity client is bundled but nothing in the build calls it.

A Cognito identity and temporary-credential client is vendored in with no call site anywhere in this build.

What

The build now carries a client for AWS Cognito Identity, covering identity lookup and temporary-credential exchange plus its error shapes. Nothing in the build calls it, so this does not by itself add a way to authenticate.

Details
  • Errors include not-authorized (403), resource conflict (409), too many requests (429), invalid identity pool configuration and developer-user-already-registered.
  • The existing STS client was reshaped from lazily initialised modules into plain top-level classes with direct exports, which mainly affects bundle load behaviour.
Evidence

Strings lifted out of the shipped bundle, so the claim above can be checked against them.
