阶梯计价数据驱动后，目录条目的字段缺失或版本拼接会直接变成计费偏差， 解析层补两道数据契约哨兵，并修正出厂快照中 Gemini pro 系的缓存写入价： - orphanCacheTierFields / warnOrphanCacheTierFields：条目带 cache 侧 above 档（含 _priority/_flex 变体与 above_1hr 形态）却没有基础价时打 WARN——cache 侧 above 档不参与计费取值，按"基础价 × 输入倍率"计，基础价 缺失即该分项按 0 计；变体缺自身基础价时沿 变体→1h→标准 回落链任一存在 即不算孤儿，与计费回落一致 - isLopsidedLongContextLadder / warnLopsidedLongContextLadders：above 档 折算出只有一侧带附加费的阶梯时打 WARN（基础价与 above 档来自不同价格 版本的形态），显式 long_context_* 字段不告警 - deriveLongContextFromAboveTierFields 注释改为陈述契约：cache above 档 须恰为基础价 × 输入倍率 - 出厂快照 6 个 Gemini pro 条目补 cache_creation_input_token_cost（= 标准 输入价，Google 对缓存写入不另收费）、above_200k 改为输入 above 价、带 priority 输入价的 4 条补 priority 孪生，与 model-price-repo 数据修正同值 测试： - 解析层：孤儿字段 WARN（含 priority/1h 孤儿正例、1h 回落 5m 反例）、单侧 阶梯 WARN、出厂快照契约（全条目无孤儿字段、无单侧阶梯、Gemini pro 缓存 写入价 = 输入价） - 用量契约：extractGeminiUsage 与 Antigravity 非流式/流式转换均不产生 cache_creation token（Gemini usageMetadata 无该类别） - 计费：gemini-2.5-pro 阶梯对 cache_read / cache_creation 分项生效，阈值 计入缓存写入 token；阶梯表场景与夹具同步为现行目录值
