The Weak Signal Cultivation Model (WSCM) provides a mathematically rigorous framework for tracking frontline risk signals across a two-dimensional coordinate field using 15 equations and 16 tunable parameters. While this specification is designed for eventual software implementation, its computational requirements create an adoption barrier for organizations whose available infrastructure is a spreadsheet. This paper introduces WSCM-Lite, a lookup-table implementation that reproduces the full WSCM's coordinate trajectories within 0.01 field units while eliminating all exponential functions, state-dependent tracking, and free parameters. The simplification replaces continuous recency weighting with a four-row lookup table and removes consensus momentum and reversal amplification entirely, reducing the specification to seven formulas and five hardcoded constants. A 26-session worked example using the Gas Fumes signal from the parent paper demonstrates that WSCM-Lite traverses the same four-region path (Question Marks --> Lit Fuses --> Owls --> Sleeping Cats --> Question Marks) and triggers SMS escalation within two sessions of the full model. Five additional scenarios validate boundary behavior, and a sensitivity analysis confirms stability under +/-30% gap threshold variation.

翻译：弱信号培养模型（WSCM）通过15个方程和16个可调参数，提供了一个数学上严谨的框架，用于在二维坐标场中追踪前沿风险信号。尽管该规范旨在最终实现软件化，但其计算需求对基础设施仅为电子表格的组织构成了采纳障碍。本文提出WSCM-Lite——一种基于查找表的实现方案，能在0.01场单位内复现完整WSCM的坐标轨迹，同时消除所有指数函数、状态依赖追踪和自由参数。该简化方案将连续权重衰减替换为四行查找表，并完全移除共识动量与反转放大机制，最终将规范缩减至七个公式和五个硬编码常数。通过母论文中“汽油味”信号的26轮次工作示例表明，WSCM-Lite沿相同四区域路径（问号→点燃引信→猫头鹰→熟睡猫→问号）行进，且在完整模型两个轮次内触发短信升级。另外五个场景验证了边界行为，敏感性分析证实其在±30%间隙阈值变化下保持稳定性。附带的Excel模拟器及补充材料已公开于https://github.com/emmgonai/wscm-lite。
