/*
 * fx-core.lib.js —— 双锚点汇率引擎（Steam 充值报价参考的取数地基）
 * ===========================================================================
 *  canonical 位置：shared/fx-core.lib.js（本仓库）
 *  消费方式：① Node/测试：require('./fx-core.lib.js')
 *           ② 油猴脚本：原样内联（见 steam-price-converter 的 inline 标记块）
 *
 * 为什么不是「一个接口一张表」：
 *   充值报价评估需要两个口径分开的锚点 ——
 *     steam：Steam 参考结算价（AugmentedSteam 交叉表，跟随 Steam 建议汇率）
 *     spot ：即期市场中间价（Frankfurter=ECB → jsDelivr currency-api → er-api）
 *   两个锚点各自独立取数、独立缓存、独立标注来源与日期；一个挂了不污染另一个。
 *
 * 血的教训（2026-11-05 实测）：
 *   open.er-api.com 免费档会返回 result:"success" + HTTP 200，但 time_last_update
 *   停在 2022-05-09。只看「有没有 rates 字段」就会把 4 年前的牌价当实时汇率。
 *   → 所有源必须做 payload 级新鲜度校验，陈旧即弃并记录 stale 来源。
 *
 * 表的形状（冻结语义，方向不许含糊）：
 *   USD 枢纽表 rates：rates[CODE] = 「1 USD 能换多少 CODE」，rates.USD === 1。
 *   CODE→CNY 的单价 = rates.CNY / rates.CODE（convert 内部走 USD 枢纽）。
 *
 * 缓存键：
 *   fxcore_spot_v1 / fxcore_steam_v1  带 1h TTL 的锚点缓存
 *   fxcore_snap_v1                    无 TTL 快照 {spot,steam,ts}，接口全挂时兜底
 *   只读救援键（不写）：swe_fx_cache / swe_fx_snap_v1 / spc_fx_snap_v1 / spc_fx_v1
 *   —— 与愿望单侧边栏、个人日历两个插件的既有 FX 链互救，快照时间如实保留。
 *
 * 宽表模式（2026-11-06 新增，opt-in，默认关）：
 *   create({ wideTable: true }) → spot 锚把多个源按优先级**逐币种合并**，
 *   而不是「取第一个成功的源」。原因：ECB(frankfurter) 只有 ~30 个币种，
 *   **RUB/TRY/UAH/VND/PHP/NOK/SEK/PLN 全都没有**（ECB 2022 年后不公布卢布），
 *   只取第一个成功的源 → 这些币种一个都拿不到。
 *   合并后 rateDate 取各源里最旧的那个（保守），source 标记 merged:<源列表>。
 *   默认关 → 其余三个插件（个人日历 / 价格换算 / 市场增强的老调用方）行为完全不变。
 * ===========================================================================

 * case-fx.lib.js —— CS2 武器箱隐含汇率（纯计算，不发请求）
 * ===========================================================================
 *  canonical 位置：shared/case-fx.lib.js（本仓库）
 *  消费方式：① Node/测试：require('./case-fx.lib.js')
 *           ② 油猴脚本：原样内联（见 steam-market-enhancer 的 INLINE 标记块）
 *
 * 这个库回答的数：花 1 美元 Steam 钱包买箱子，按 BUFF 在售价卖掉能换回多少人民币。
 *   毛汇率 = BUFF在售最低价(CNY) / Steam美元区买家价(USD)
 *   净汇率 = 毛汇率 × (1 - buffFee)
 *   价差   = 净汇率 - 卡价          正数 = 箱子套现比卡价多出的人民币/美元
 *
 * 美元区买家价是美金卡入账之后真正付出的钱包美元（标价已含 Steam 购买侧费用）。
 * buffFee 只扣 BUFF 卖出手续费。不要再乘挂刀比价用的 0.85：那是另一条路径
 * （Steam 卖出到手 vs 第三方），乘进来会把价差算没。
 *
 * 标题汇率是有效箱子净汇率的中位数。偏离中位数超过 outlierPct、或 24h 成交量
 * 低于 minVolume 的不计入。有效只数 < minCount 时 median 为 null（unknown≠0）。
 *
 * 2026-11-06 改造（v2.2.0，依据见 fxq.lib.js 库头「血的教训」）：
 *   ① **离群阈值从 8% 收紧到 3%**，但阈值不是死数：
 *      实际判定用 `dev > max(outlierPct, 本行误差 + 中位数误差)`。
 *      理由：箱子单价只有 $0.12~$1.12，两位小数量化误差就有 ±0.4%~4.2%，
 *      固定 8% 抓不到量化噪声（实测 Kilowatt lowest 口径偏 5%），
 *      而固定 3% 又会把纯噪声当离群剔掉 → 必须让阈值跟着本行的精度走。
 *   ② **价格口径由调用方决定**（本库不猜）：调用方可用 steamPrice/buffPrice
 *      传入稳健统计量（Steam median / BUFF 前三档均价），
 *      缺省时仍用 steamUsd/buffCny（向后兼容，老调用方不受影响）。
 *   ③ 每行带 errPct（该行价格的量化误差上界），返回值带 uncertainty
 *      （有效样本里的最大误差，保守取 max）→ 调用方必须把它显示出来，
 *      精度不够的数字不能显示得像精确值。

 *
 * 为什么要有这个库（借鉴 AetherSwap 的 CV + R² 选品思想）：
 *   「史低 / 降价提醒」只有在低波动序列上才可信 ——
 *   CV 0.4 的物品今天史低，明天可能再跌 20%，跌破阈值是家常便饭而非机会；
 *   而持续阴跌（slope<0 且拟合度高）的「降价」是趋势而非买点。
 *   用两个正交维度给序列定性：
 *     CV（变异系数 = 样本标准差 / 均值）  —— 震荡幅度，量纲无关，可跨价格量级比较
 *     R² + slope（对下标的最小二乘回归） —— 趋势方向与置信度
 *
 * 分级语义（classifyVol，阈值冻结）：
 *   stable    cv ≤ 0.05            波动小，提醒可信度高
 *   normal    0.05 < cv ≤ 0.15     一般
 *   volatile  cv > 0.15            价格剧烈震荡，阈值提醒参考价值低
 *   declining slope<0 且 r2 ≥ 0.6  趋势性下跌（覆盖上面的分级，最优先判定）
 *
 * 输入约定：prices 为数值数组；空 / 单元素 / 均值≤0 / 含非有限数一律返回 null

 *      而 **CNY +0.78%** → 这层摩擦是人民币钱包专属，不是全局手续费。
 *      → 「Steam 参考价」必须实测反推，不能引用第三方表。
 *   ② **价格量化误差 = ±0.005/price**（两位小数取整）。$76 档 ±0.01%，$0.12 档 ±4.2%。
 *      用 lowest_price 算「汇率」会把单个错价挂单放大成 5% 偏差
 *      （实测 Kilowatt lowest 隐含 6.3333 vs median 隐含 6.6667），
 *      而 8% 的离群阈值**根本抓不到** → 必须用稳健统计量 + 显式标注不确定度。
 *   ③ **价格串是本地化的**：EUR 是 "67,79€"、JPY 是 "¥ 12,054"、CNY 是 "¥ 510.83"。
 *      用 `/[\d.,]+/` 一把梭会把 "1,234.56" 解析成 1.234（**1000× 错**）
 *      → 必须按币种小数位解析（parseMoney）。

    // ==================== v2.0.0 统一存储层（IndexedDB） ====================

    //   旧版存储是**四轨并存** —— 设置走 GM_getValue、缓存走 localStorage、
    //   池子/比价走 GM、补充包/MR/库存又走 localStorage。
    //   后果：① localStorage 5MB 配额被缓存吃掉并频繁触发 QuotaExceededError
    //        ② GM 侧无容量管理，池子日快照可能静默撑爆配额
    //        ③ 无 schema / 无版本，换存储格式无从谈起
    // 现在统一到 IndexedDB：
    //   · db `sme_store` v1，三个 object store：
    //       settings —— 键值设置（迁移自 GM_getValue）
    //       cache    —— 带 TTL 的缓存条目（迁移自 localStorage 的 sme_cache_*）
    //       kv       —— 通用 KV（迁移自 localStorage / GM 的其余键）
    //   · 读：**内存镜像优先**（同步），保证 settings.get / cache.get 的同步语义不变
    //   · 写：内存同步 + IndexedDB 异步落盘（write-behind），不阻塞 UI
    //   · 兜底：IndexedDB 不可用（隐私模式 / 老浏览器）→ 自动退回 GM + localStorage，功能不挂

     *
     * ① **全库存浮盈浮亏**（对标 PriceCharting / SIH 的收藏品 P&L）
     *    · 成本基准：成交记录按 **FIFO** 配对；成本用**卖家到手价**（买家支付价 − 手续费），
     *      否则「买入即亏手续费」会让成本虚高、浮亏虚高。
     *    · 已实现盈亏：卖出按 FIFO 消耗买入批次；买入发生在索引窗口之外的，
     *      单独记「成本未知」计数，**不猜成本**。
     *    · 未实现盈亏：现价用 `priceoverview` 的最低卖价（与市场实际可成交价一致）。
     *
     * ② **交易冷却可视化**（7 天不可再挂 / Trade Protection）
     *    · 冷却天数：取自 Steam 自己的 `descriptions[].market_marketable_restriction`
     *      （Valve 游戏为 7 天；已实测这是**类级别天数**而非剩余天数）。
     *    · 解锁日：获得时间（市场买入时间，来自成交记录）+ 冷却天数。
     *    · 交易/赠送所得的物品没有买入记录 → 起始时间未知，如实标注「来源未知」，
     *      **不编造解锁日期**。
     *
     * 两者都放在「市场交易记录分析」浮窗里（同一份成交记录数据源，不额外抓取）。

     * Markdown 单元格转义 —— 标准 GFM 反斜杠转义。
     *
     * 为什么用标准 `\|` 而不是实体 `&#124;`：
     * 历史上为了迁就 scripts-tools/markdown-reader 不认反斜杠的缺陷而改用实体，
     * 代价是源码视图里全是 `&#124;` 这类噪声。v1.6.7 起 reader 已支持标准转义，
     * 故回归 GFM 标准写法 —— 通用 Markdown 工具链（GitHub / VS Code / Obsidian /
     * marked.js 等）都认它，源码也更好读。
     *
     * 两条兼容保证：
     *   - 新导出（本函数，标准转义）→ 新 reader ✓
     *   - v1.6.6 之前的旧导出（实体 &#124;）→ 新 reader ✓（escapeHtml 保留已有实体）
     *
     * 字符分工：
     *   & < >    → HTML 实体（HTML 上下文，任何渲染器下都安全）
     *   其余语法符 → 反斜杠转义（Markdown 标准）
     *
     * 单次扫描完成映射，避免 & 先被转成 &amp; 后自己插入的实体又被二次编码。

    // ==================== v1.7.0 我的池子行情 ====================
    /**
     * 「我的池子行情」
     * =========================================================================
     * 把「我关心的那一批社区市场物品」聚合成一张行情盘，对标参考图那类行情 App 的形态
     * （指标卡 / 指数曲线 / 板块行情 / 市场热图 / 我的池子明细），
     * 但数据域是 **Steam 社区市场**，不是商店折扣。
     *
     * 为什么是「我的池子」而不是「全市场」：
     *   社区市场**没有全市场 API**——Steam 只提供逐物品的
     *   pricehistory / itemordershistogram，没有任何"全市场行情"端点。
     *   纯客户端做不出全市场指数。能做且有意义的是「我关心的这一批」的指数。
     *   池子来源：① 浏览市场时自动收录（可关）② 详情页手动关注 ③ 库存页批量收录。
     *
     * 数据模型（落在 GM 存储，不占 localStorage 的 5MB 配额）：
     *   poolState.items  Map<`appid::hashName`, {appid,hashName,name,game,kind,sources,qty,addedAt,lastSeen}>
     *   poolState.series Map<`appid::hashName`, [[dayIdx, cents, vol], ...]>
     *   dayIdx = Math.floor(ts / 86400000) —— 相对 1970-01-01 的天数，5 位数，比时间戳省一半
     *
     * 口径纪律（每条都是"错一条整张盘就歪"的级别，务必保持）：
     *   · 「当前价」= 当日成交价按成交量加权（VWAP）；无成交量退化为当日收盘价。
     *     ★ pricehistory 返回的 p 是**单位金额**（如 20.70），不是分 —— 入库要 ×100。
     *   · 「指数」= 基期（窗口内首个有价日）= 100 的成交量加权价格指数。
     *     权重 = 物品在窗口内的总成交量（固定），这样逐日变化只反映价格变化、不受权重漂移影响。
     *   · 「前值延续」= 物品当日无成交时沿用最近一次有价，但最多延续 7 天，超过则视为无价。
     *   · 「历史新低」= 当前价 ≤ 窗口内最低价（容差 0.5%）。
     *   · 所有占比类指标都要写明分母（参与计算的物品数），不能只给一个百分比。

    /**
     * 「价格提醒」——竞品（SIH / Steam Helper / 各聚合站）都有、本插件此前完全缺失的能力。
     *
     * 设计取舍：
     *   · **只读、不写**：只调 priceoverview 与池子已有的日快照，不碰任何下单接口
     *     → ToS 风险最低，也最不容易把账号搞出问题。
     *   · **基准是「添加提醒那一刻的价格」**，不是滚动均值 —— 用户要的是
     *     「我记下的那个价，跌了多少」，滚动基准会让人看不懂。
     *   · **幂等**：同一价位只通知一次（smeAlertCheck 判定），避免每轮轮询重复推送。
     *   · 优先复用池子的日快照（零请求）；没有快照才回退 priceoverview。
     *
     * 数据落在 IndexedDB 的 kv store（键 sme_alerts_v1）。
