Summary

Puppet::Indirector::Hiera is explicitly marked deprecated and slated for deletion.

Evidence

• lib/puppet/indirector/hiera.rb:8 says the class is deprecated and will be deleted in a future release.
• File comment points users to Puppet::DataBinding.indirection.terminus(:hiera).

Proposed OpenVox 9 Change

• Remove Puppet::Indirector::Hiera.
• Route all supported lookups through Puppet::DataBinding mechanisms.

Compatibility / Risk

• Medium risk for plugins directly requiring or subclassing Puppet::Indirector::Hiera.
• Need clear migration note for plugin maintainers.

Implementation Notes

• Find internal references and update callers.
• Add release-note callout for plugin ecosystem.
• If needed, leave temporary compatibility constant that hard-fails with explicit migration message (time-boxed).

Acceptance Criteria

• lib/puppet/indirector/hiera.rb removed.
• No core code path references this class.
• Lookup behavior remains correct through supported data-binding interfaces.

Suggested Tests

• Data-binding integration tests for successful lookups and merge behavior.
• Negative test confirms deprecated class is not usable (or emits intentional hard failure).
