# signal_v3 deterministic split summary

- source: `synthetic_data/signal_v3.jsonl`
- seed: `glyph-signal-v3-clean-sft-rlvr-split-v1`
- method: stratified by `family`, `difficulty`, expected tool-sequence length, and run/test verifier family; grouped by `case_id` to prevent duplicate trace leakage.
- leakage checks: case_id overlap `0`, trace overlap `0`
