-## Policy
-
-- No dataset-wide MIT claim is made for upstream source content.
-- Per-chunk `upstream_license`, `source`, and `source_url` fields are authoritative.
-- Unknown licenses remain in the export and should be filtered for conservative enterprise use.

-# depthapi_technical_corpus
-
-## Summary
-
-`depthapi_technical_corpus` is a mixed-license retrieval corpus built from technical documentation, books, engineering writeups, and repository-derived reference material. It is intended for open-source RAG systems, embedding benchmarks, reranker evaluation, and enterprise retrieval experiments.
-
-## Ingestion Process
-
-The corpus was assembled from multiple upstream source types and normalized through a reproducible local pipeline backed by Supabase.
-
-- `Scrapling` was used for live technical documentation crawling and structured HTML extraction from documentation websites.
-- [`D4Vinci/Scrapling`](https://github.com/D4Vinci/Scrapling) was used for live technical documentation crawling and structured HTML extraction from documentation websites.
-- [`opendataloader-project/opendataloader-pdf`](https://github.com/opendataloader-project/opendataloader-pdf) was used for PDF extraction when ingesting book-like and document-style technical sources into normalized markdown/text blocks.
-- Source material was then normalized, rechunked deterministically, deduplicated, validated, and exported to parquet for Hugging Face datasets compatibility.
-
-## Schema
-
-Each chunk includes:
-
-- `chunk_id`
-- `source`
-- `source_url`
-- `upstream_license`
-- `document_id`
-- `chunk_index`
-- `retrieved_at`
-- `chunker_version`
-- `content_hash`
-- `content`
-
-## Usage
-
-```python
-from datasets import load_dataset
-
-dataset = load_dataset("sanjeevafk/depthapi_technical_corpus", split="train", streaming=True)
-for row in dataset.take(3):
-    print(row["chunk_id"], row["source"], row["upstream_license"])
-```
-
-## Retrieval Benchmark Example
-
-Use `data/research_corpus/benchmarks/queries.jsonl` with your retriever and score against `qrels.jsonl`.
-
-## Licensing
-
-This is a mixed-license dataset. Downstream users must inspect `upstream_license` and `SOURCES_MANIFEST.yaml` before redistribution or commercial use.
