# R6 detection_log edge regression — S8-DETECTION-LOG-EDGE-FIXTURE-1（dev/test only, aidopdev）。
#
# 演变史：
#   - 旧版基于 G01_TEST_TIMEOUT_NO_HIT / G01_TEST_TIMEOUT_FAILED；这两条 fixture 已从 dev 移除。
#   - 上一轮 SCAN-1 改造为 SKIP（CREATED/REFRESHED 由 sched-exec 覆盖）。
#   - 本轮 EDGE-FIXTURE-1 引入 TEMP_SCHED_TIMEOUT_NO_HIT / TEMP_SCHED_TIMEOUT_EVALUATE_FAILED
#     真实覆盖 NO_HIT 与 EVALUATE_FAILED 两条 detection_log 边缘路径。
#
# 验证机制：
#   - 通过 watch_rule.next_run_at=NOW 触发 Job tick 调度，最多 90s 轮询 last_run_at 推进。
#     Job 路径（RunDispatchTickAsync→ProcessSingleRuleAsync）写 detection_log + 更新
#     watch_rule.last_status / last_error / consecutive_failure_count，CTO 任务约束 五.B 要求。
#   - NO_HIT：valid params + 表达式返回未到期行 → evaluator 0 hits → NO_HIT 日志。
#   - EVALUATE_FAILED：params_json 缺 dueAtField → evaluator 抛 S8RuleEvaluatorException
#     (reason=params_schema_invalid) → EVALUATE_FAILED 日志 + last_status=FAILED。
#
# 严守：
#   - 不影响 demo rule 10/11/12。
#   - TEMP rule 测后 enabled=0；TEMP exception 若有 soft delete（理论上两条都不应建单）。
#   - 不清 detection_log / rule_detection_state / 演示 exception。
