Summary

Two settings in automatic data binding are deprecated and should be removed in favor of Hiera 5 patterns.

Evidence

• lib/puppet/defaults.rb:548 marks data_binding_terminus behavior as deprecated.
• lib/puppet/defaults.rb:558 emits deprecation warning for non-hiera use.
• lib/puppet/defaults.rb:750 marks environment_data_provider as deprecated.
• lib/puppet/defaults.rb:754 emits deprecation warning for environment_data_provider.

Proposed OpenVox 9 Change

• Remove data_binding_terminus setting.
• Remove environment_data_provider setting.
• Keep supported lookup/data provider behavior through Hiera 5 configuration.

Compatibility / Risk

• Medium to high risk for installations with custom automatic data provider pipelines.
• Requires migration guidance for environment/module authors.

Implementation Notes

• Confirm equivalent behavior via Hiera 5 API/config.
• Update related warnings/docs in lookup adapter code if they assume these settings exist.
• Add release notes with migration examples.

Acceptance Criteria

• Both settings are absent from defaults, docs, and config parser support.
• No deprecation warnings for these keys remain.
• Lookup behavior for supported Hiera configurations remains stable.

Suggested Tests

• Integration tests for Hiera 5 lookup flows across environments.
• Negative tests for removed settings in config files and CLI.
