# Stage 1 data report

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.

## Version dedup (strict rule; an older version is kept only if it differs by more than 5 % of lines)

- Object families: 269; with more than one version: 39.
- Versions kept: 323. Versions removed: 12.
- Records: 370 before, 353 after.
- Tokens before: 2806501 (chars/4 estimate 2636112). After dedup: 2658082. After splitting: 2660834.
- Rule: main (Cloud) and the newest v* (Standard ABAP) always kept; each older v* compared with the next newer v*; other branches (0 comparisons) compared with main.

## Splitting of documents over the limit

- Documents split: 41; pieces: 82; hard line splits (a block was too big): 15; pieces still over the limit: 0.
