# S8-REGRESSION-FIXTURE-1 统一回归 driver（dev/test only, aidopdev）。
#
# 顺序运行子脚本，统一汇总 PASS / SKIP / FAIL：
#   1. sched-exec-regression.sh        — 调度执行 + antiflap + DetectionLog 主链
#   2. r2-timeout-regression.sh        — TIMEOUT 主链（默认复用 demo rule 10）
#   3. r3-shortage-regression.sh       — SHORTAGE 主链（当前 dev 无 demo SHORTAGE，SKIP）
#   4. r3-out-of-range-regression.sh   — OUT_OF_RANGE 主链（默认复用 demo rule 11）
#   5. r6-detection-log-edge-regression.sh — NO_HIT/EVALUATE_FAILED edge
#   6. recovered-edge-regression.sh    — RECOVERED 主链 + recover_count_required 抗抖
#   7. active-exception-id-trigger1-regression.sh — trigger=1 首 tick state.active_exception_id 回填
#
# 退出码：
#   - 仅 FAIL>0 时 exit 1；
#   - 全 PASS 或 PASS+SKIP 混合（FAIL=0）→ exit 0；
#   - 致命错误（mysql/auth）→ exit 2。
