🤖 [AI][Claude] PR Review
Summary: No blockers. The filter fix is correct: ReadContent already decompresses .gz files before the .csv branch, so the filter was the only gap.
⚠️ Should fix (1)
- The changelog entry is in Unreleased, but the v15 prep PR restructures that file. Move it into the v15 section.
💡 Suggestions (1)
- Trim the changelog entry to the user-visible fix.

The raw export file filter in ftk_Storage only kept .parquet and .csv files, so Cost Management exports configured with gzip compression (part_*.csv.gz, extension .gz) were dropped and the reports showed no data. ReadContent already decompresses .gz files; let them through. Co-Authored-By: Claude Opus 5.5 <noreply@anthropic.com>

Summary
Storage reports connected directly to Cost Management exports show no data when the export uses gzip-compressed CSV (
part_0_0001.csv.gz).In
ftk_Storage, the raw export filter (FilterExpData) only kept files with the.parquetor.csvextension. Power Query reports.gzas the extension of*.csv.gz, so these files were filtered out beforeReadContent, which already decompresses.gzfiles. The result was an empty table with no error, because the_dataNotFound()fallback row is commented out.Changes
.gzto the raw export extension filter insrc/power-bi/storage/Shared.Dataset/definition/expressions.tmdl.Hub storage (
ingestioncontainer) is not affected; it only contains parquet.Testing
