/*
 * 模块名称：量纲回归主机侧单测（「数据可信」量纲回归用例 · 道A）
 * 被测对象：真实源文件（#include 原样纳入，全链路 L1.5→L2→L3）：
 *             adc_cal.c + prot_set.c + sample_ring.c + phasor.c + freq.c +
 *             prot_elm.c
 *           平台依赖桩：dbg_log.h（stub/）、cfg_file_register（捕获计数）、
 *           adc_input_desc（V0.1 权威来源表，同 adc_cal 套件）。
 *
 * 本套件的存在理由（短板评测 + 「数据可信」§2.2）：台架此前"通过"是因为没有
 * 一条判据检查**不该动作时不动作**——"码值当工程量"的错配曾让 OC 拿 ~11000
 * 码值比 10 A 定值恒假动作。本套件把这条固化成回归：用例从 **ADC 码值** 出发、
 * **显式写出码值↔二次值换算**，走真实 折算→采样环→全周傅氏→元件判据 链；
 * 任何一环把量纲弄丢（比如折算点被旁路），断言立刻翻转。
 *
 * ROM 系数覆写（#undef/#define）：把"板级理论系数"替换为合成端子侧口径
 * （10 mV/码，K_DIM），模拟两点标定完成后的 ROM/默认状态——合法带随之
 * 锚定合成值，adc_cal_set 走正规路径置 VALID，测试不白盒改引擎内存。
 *
 * 覆盖点（族 TC-HOST-PROTDIM，属主登记处 = 本目录）：
 *   TC-PROTDIM-001  标定链基线：0.5 A/100 V/0 V 注入 → 七类元件全静默（含
 *                   OL：0.5 < 1 A 定值）+ IA 相量有效值 = 0.5 A ±0.5 %
 *   TC-PROTDIM-002  反错配对照：同一批码值，raw 直灌 → OC1 假动作（复现历史
 *                   事故）；经 adc_cal_apply → OC1 静默（折算点不可旁路）
 *   TC-PROTDIM-003  OC1（10 A，dly=0）：9.995 不动作 / 10.5 启动即动作 /
 *                   9.6 滞回保持 / 9.49 释放
 *   TC-PROTDIM-004  OC2（5 A，500 ms）：6 A 启动，启动后 499 ms 不动作、
 *                   501 ms 动作；4.8 保持（ret 4.75）、4.6 释放
 *   TC-PROTDIM-005  OC3（2 A，3000 ms）：同上时序（2.1 A）
 *   TC-PROTDIM-006  OL（1 A，10 s）：1.05 A 启动、9999/10001 ms 时序、
 *                   0.96 保持（ret 0.95）、0.93 释放
 *   TC-PROTDIM-007  OV（120 V，10 s）：100 V 静默；121 V 启动、到点动作；
 *                   115 保持（ret 114）、113 释放
 *   TC-PROTDIM-008  UV（20 V，10 s，欠量方向）：21 V 静默；19.9 V 启动、
 *                   到点动作；20.5 保持（ret 21）、21.6 释放
 *   TC-PROTDIM-009  3U0（15 V，5 s）：14 V 静默；15.1 启动到点；
 *                   14.4 保持（ret 14.25）、14.1 释放
 *   TC-PROTDIM-010  聚合与独立性：OC1+OV 同拍动作位图 = 双位；撤 IA →
 *                   OC1 返回、OV 保持（互不污染）
 *
 * 通过：全部 TC PASS（main 返回 0）。
 * 创建日期：2026-10-25（道A 量纲回归用例）
