SFT-v3 training corpus (clean) — 138 trajectories

Best-of-pool trajectory per synth DiscoveryBench task, from 21 runs across 4 sources (8b-fold 58 / 8b-ctxgraph 44 / 8b-react 30 / 30b-ctxgraph 6), all rendered under the ctxgraph code_graph prompt. 62/200 synth tasks were EXCLUDED by a data audit (gold hypothesis references constant/missing columns in the task's own data — see audit_synth_tasks.py); corpus covers all 138 clean tasks.

Selection (threshold-light): binary gates score>0 and zero truncation retries; rank by (score desc, >=5 assistant turns preferred, duplicate-code ratio asc). Judge for selection: gpt-5-nano (Azure). Mean assistant turns 3.8.

Columns

col description
task_id synth task id
source teacher pool source (8b-fold / 8b-ctxgraph / 8b-react / 30b-ctxgraph)
score judge HMS score of the winning trajectory on its synth task
n_messages messages in the conversation
messages_json FULL multi-turn conversation (system/user/assistant), no truncation

Used by scripts/train_sft.py (LoRA r16, 2 epochs, loss on assistant tokens only). Experiment: browsecomp-ctxgraph-30b-rl (distillation v3). Status: final.
