## Summary
Additional environment API keys can use SDK APIs that require public
access tokens. The SDK detects the additional-key format and asks the
Trigger.dev server to mint scoped tokens instead of attempting to sign
them locally.
Root environment keys retain their existing local-signing behavior.
Trigger and batch clients also prefer server-issued tokens returned in
response headers while preserving compatibility with older servers.
## Deployment notes
This package update is safe to publish before servers expose additional
key creation. Existing root keys continue to use the current path, while
an additional key used with an older server fails with an actionable
upgrade error.
