Conversion Quality

Limited

Why this is only a partial conversion

The Sentinel version can compare planned event bus resources against planned policy resources cleanly inside its own collection-processing model. tfpolicy can approximate that by using core::getresources() and matching on event_bus_name, but this is not a full graph-aware translation.

Key translation notes

• Related resources are discovered with core::getresources("aws_cloudwatch_event_bus_policy", {})
• Matching is done by explicit value (event_bus_name) rather than graph/reference semantics
• A top-level lookup map keeps the tfpolicy example readable and performant

Limitations encountered

• This approach relies on resolved attribute values, not reference metadata
• New resources with unresolved references may not match reliably on initial creation
• core::getresources() is useful for scoped lookups but is not a full replacement for Sentinel graph traversal
