 ## [Unreleased]
 
+### Added
+
+- *(hf-bucket)* `HfBucketSink`: terminal sink writing parquet/json/csv
+  windows to a Hugging Face storage bucket. Uploads go through Xet
+  (`hf-xet` crate) with chunk deduplication, then register via the
+  sans-IO `BatchAction` (`POST /api/buckets/{bucket}/batch`). Also adds
+  `CreateBucketAction`. Opt-in feature `hf-bucket`; requires Rust 1.89+
+  (transitive `redb` MSRV).
+- *(hf-bucket)* `nea_weather_bucket` example: the reference NEA pipelines
+  writing to a storage bucket; collectors, records, and config plumbing
+  are now shared with the dataset example via `examples/common/mod.rs`.
