Greptile Summary

• Fixed bug where loop/parallel blocks were not accessible in tag dropdown when referenced from within their own subflows
• Removed deprecated currentIteration field throughout codebase, replaced by existing index field which serves the same purpose

Confidence Score: 5/5

• This PR is safe to merge with minimal risk
• The changes are straightforward bug fixes with good test coverage. The main fix adds loop/parallel IDs to accessible references, which is a logical enhancement. The removal of currentIteration is a clean refactor since index already provides the same functionality (both resolve to loopScope.iteration). All changes are consistent across the codebase with no breaking changes.
• No files require special attention

    Note over Resolver: At runtime, loop.index resolves to loopScope.iteration
