# Stage 1 data report
Corpus: `/Users/erhankeseli/projects/abap-llm/corpus/corpus.jsonl` (source abap-cheat-sheets, Apache-2.0, see corpus/out/ATTRIBUTION.md).
Corpus: `/Users/erhankeseli/projects/abap-llm/corpus/corpus.jsonl` (SAP-samples/abap-cheat-sheets, Apache-2.0, see corpus/out/ATTRIBUTION.md).
Tokenizer: `/Users/erhankeseli/models/Qwen3.8-27B-4bit`. Seed 20261003. max_seq_length 16384.
Split by family (release versions and parts of one document stay together): 180 families.
## Version dedup (keep the newest; keep an older version only if it differs by more than 5 % of lines)
- Object families: 269; with more than one version: 39.
- Versions kept: 319. Versions removed: 16.
- Records: 370 before, 351 after.
- Tokens before: 2806501 (chars/4 estimate 2636112). After dedup: 2699110. After splitting: 2701996.
- Info: a stricter rule (compare also with the other kept versions) would remove 8 more kept versions.
## Splitting of documents over the limit
- Documents split: 43; pieces: 86; hard line splits (a block was too big): 17; pieces still over the limit: 0.
