+A fail-closed Polish academic-book subset extracted from the official ROCK repository of Lublin University of Technology.
+
+- Retained books: 8
+- Text characters: 3,380,937
+- Tokens: 1,177,858 (`cl100k_base` proxy)

+The acquisition target was 20 books, but only eight passed the conservative per-file rights gate. The other inspected candidates are not included. See `NOTICE.md` and `artifacts/` for attribution, decisions, the source inventory, deterministic complete-record samples, QA, checksums, overlap audit and Slayer ontology manifest.
+
+## Limitations
+
+PDF extraction can flatten tables and equations. Two isolated unreadable glyphs were marked explicitly. Pattern-based PII checks are not comprehensive de-identification. No title overlap was detected against the pinned `biblioteka_nauki` attribution column, but target-wide text deduplication, benchmark checks and controlled training ablations remain pending.

+# ROCK Politechnika Lubelska PL books
+
+A fail-closed Polish academic-book subset extracted from the official ROCK repository of Lublin University of Technology.
+
+- Retained books: {stats['kept']}
+- Text characters: {stats['characters']:,}
+- Tokens: {stats['tokens']:,} (`cl100k_base` proxy)
+- Author coverage: {stats['author_coverage']:.1%}
+- License: CC BY-SA 4.0, confirmed for every retained item and matched PDF bitstream
+- Source period: 2023-2026
+
+The acquisition target was 20 books, but only eight passed the conservative per-file rights gate. The other inspected candidates are not included. See `NOTICE.md` and `artifacts/` for attribution, decisions, the source inventory, deterministic complete-record samples, QA, checksums, overlap audit and Slayer ontology manifest.
+
+## Limitations
+
+PDF extraction can flatten tables and equations. Two isolated unreadable glyphs were marked explicitly. Pattern-based PII checks are not comprehensive de-identification. No title overlap was detected against the pinned `biblioteka_nauki` attribution column, but target-wide text deduplication, benchmark checks and controlled training ablations remain pending.

+Adds `{SOURCE}`: **{stats['kept']} complete books and {stats['tokens']:,} measured `cl100k_base` proxy tokens** from the official ROCK repository of Lublin University of Technology.

+Source dataset: https://huggingface.co/datasets/{OWN_REPO}/tree/{source_commit}
+
+### Data sample
+
+- [{stats['sample_count']} deterministic complete-record samples](https://huggingface.co/datasets/{OWN_REPO}/blob/{source_commit}/artifacts/sample.jsonl)
+- [Per-record attribution, source URLs and item/PDF rights evidence](https://huggingface.co/datasets/{OWN_REPO}/blob/{source_commit}/artifacts/attribution.jsonl)
+- [Fail-closed acquisition inventory and exclusions](https://huggingface.co/datasets/{OWN_REPO}/blob/{source_commit}/artifacts/inventory.json)
+
+### Rights and method
+
+Every retained record exposes CC BY-SA 4.0 in both the ROCK item record and the matched original PDF bitstream metadata. The publisher policy, source URLs, checksums and attribution are preserved. The acquisition target was 20 records; only these eight passed the conservative per-file gate. Text was extracted with pdfplumber, normalized, checked for limited PII patterns, and exact/near-deduplicated within source.
+
+### Overlap and Slayer ontology
+
+No exact or fuzzy title match was detected against all 42,071 rows of `biblioteka_nauki` at pinned DynaWord revision `{load(out / 'overlap_audit.json')['target_revision']}`. This is metadata evidence, not target-wide text deduplication. The manifest separates content-addressed source/dataset Versions, Protocol, Run, Evidence, falsifiable Claims, Actors and typed lineage. Cross-source text deduplication, benchmark checks, review of quoted third-party text and controlled training ablations remain pending. This PR proposes a source, not a merged or stable release.
