+# Completed Bagpiper SFT format conversion
+
+Both original SFT datasets are fully converted and publicly uploaded in portable lossless ESPnet dialogue format.
+
+| Release | Preserved rows | Verified archives | Converted archive bytes |
+| --- | ---: | ---: | ---: |
+| [Bagpiper SFT](https://huggingface.co/datasets/espnet/Bagpiper_SFT_Data_ESPnet) | 2,667,017 | 6,804 | 719,295,381,339 |

+
+See FINAL_REPORT.json and each release's RELEASE_VALIDATION.json for precise statistics and pinned source revisions. Original encoded audio bytes, all rows, ordered text and roles, and provenance are preserved. Duplicate audio storage is removed within conversion streams; extraction verifies and merges identical files across streams. Original source repositories remain available. Their data cards now link directly to the converted training format.
+
+The publicly downloaded preparation helper safely extracts audio, resolves local paths, checks global IDs and provenance linkage, and writes ESPnet all/train/valid manifests. The optional suggested validation split uses audio SHA256; all.json preserves the original complete pool. Source data terms and recipe-v1/paper-v2 selection are unchanged.
+
+All source and remote archive hashes were reconciled. Actual ESPnet reading and exact original-versus-converted waveforms passed for the documented samples. Seven regression tests pass. No GPU training or inference was performed.
+
+ESPnet recipe preparation documentation is ready as local commit 22666931398cecebf7c0646ca091b26fdacc559d and recipe-preparation.patch. GitHub publication was blocked by automatic approval review because the saved credential source was not specifically authorized; the permission question remains pending. This does not affect either completed Hugging Face release.
