agentbadcasesignalmapper

Attach structured bad-case signals and a conservative tier to each sample.

Design goal: precision over recall for the high_precision tier.

Upstream coverage (when present in the pipeline):

• meta: tool_*, usage tokens, primary_tool_type, dominant_tool_types, dialog_intent_labels, dialog_topic_labels, dialog_sentiment_labels, agent_turn_count, lineage keys.
• stats: llm_analysis_*, llm_quality_*, llm_difficulty_*, text_len, num_words, perplexity, lang_score.
• meta: optional dialog_* / agent_trace_coherence / agent_tool_relevance records (1–5 scores from lightweight LLM mappers).

Each signal group can be toggled via constructor flags. high weight feeds high_precision tier (with config); medium feeds watchlist only.

Tool-heavy agent runs: use min_tool_fail_count_for_signal to avoid treating a single exploratory tool error (common before recovery) as strong bad-case evidence.

P-percentile calibration (optional): set auto_calibrate_thresholds and calibration_json_path to a JSON file produced by demos/agent/scripts/compute_percentile_thresholds.py --write-calibration. Per-sample thresholds merge default with by_request_model using meta.agent_request_model. When calibration_manual_overrides_auto is true (default), explicit max_total_tokens / max_latency_ms / perplexity settings in YAML override the file; set it false to prefer calibration.

为每个样本附加结构化的 bad-case 信号 和保守的 层级。

设计目标：对于 high_precision 层级，精确率优先于召回率。

上游覆盖范围（当存在于 pipeline 中时）：

• meta：tool_*、usage token、primary_tool_type、dominant_tool_types、 dialog_intent_labels、dialog_topic_labels、dialog_sentiment_labels、 agent_turn_count、lineage keys。
• stats：llm_analysis_*、llm_quality_*、llm_difficulty_*、 text_len、num_words、perplexity、lang_score。
• meta：可选的 dialog_* / agent_trace_coherence / agent_tool_relevance 记录（来自轻量级 LLM mapper 的 1-5 分评分）。

每个信号组均可通过构造函数 flag 进行切换。high 权重馈入 high_precision 层级（通过 config 配置）；medium 仅馈入 watchlist。

工具密集型 agent 运行： 使用 min_tool_fail_count_for_signal 以避免 将单次探索性工具错误（在恢复前很常见）视为强烈的 bad-case 证据。

P 百分位数校准（可选）：将 auto_calibrate_thresholds 和 calibration_json_path 设置为由 demos/agent/scripts/compute_percentile_thresholds.py --write-calibration 生成的 JSON 文件。 逐样本阈值使用 meta.agent_request_model 将 default 与 by_request_model 合并。 当 calibration_manual_overrides_auto 为 true（默认值）时，YAML 中显式的 max_total_tokens / max_latency_ms / perplexity 设置将覆盖该文件；将其设为 false 则优先使用校准值。
