/auto-version — Snapshot on PIVOT/REFINE

借鉴 AutoResearchClaw --incremental-experiment + ARIS W3 --pivot。

Overview

防 v3 / v4 / v5 / v6 在同一 checkout 互相覆盖。

REFINE/PIVOT 决策出来后自动：

runs/stage-1_v6_meta/ → runs/_archive/stage-1_v6_meta_<ts>/

并写新 run 的 prompt 模板：

# CONTINUATION
Previous run reached SR=87% at step 35M; loss plateaued from step 28M.

# PRIOR PLAN
KL-distillation against 5 guidings, lr=4e-5, KL_weight=0.01.

# DELTA
- bump KL_weight to 0.05 (per /pivot reasoning)
- new sprint_contract.yaml signed at <hash>

Workflow

TS=$(date +%y%m%d_%H%M)
SRC=${1:-runs/$(ls runs | sort | tail -1)}
DEST=runs/_archive/$(basename $SRC)_$TS
mkdir -p runs/_archive
mv $SRC $DEST
# emit 3-part prompt to next-run.md
python3 tools/auto_version.py emit-prompt --archived $DEST --label $LABEL > runs/$LABEL/PROMPT.md

Output

• runs/_archive/<old>_<ts>/
• runs/<new-label>/PROMPT.md

Composition

• /pivot REFINE/PIVOT 后自动调
• /audit-driven-retrain 每轮先调
