v0.1.9

Bug Fixes

• fix: resolve FileUDFResult lineage by source_mapping index, not source_guid scan (#220)
  • FILE-mode tools with multiple input records sharing the same source_guid (e.g. after flatten) now produce correct per-record lineage instead of all inheriting the first match
  • Fixes silent downstream data duplication when using context_scope.observe on pre-flatten ancestors
  • source_mapping is now fully consumed by the runtime — no longer validated-then-discarded
