-### Multi-dimensional Analysis
+### Dual Scoring System
 
-Evaluates five dimensions: contribution count, merge rate, code reviews, tenure, and community presence.
+Two independent scores — **Repo Trust Score** (context-specific) and **Profile Score** (global profile) — each rated 0–100 across four dimensions.

 ## How Scoring Works
 
-Each contributor is scored across five dimensions, normalized to 0–100:
+OSS Stamp computes two independent scores, each 0–100 with four dimensions.
+
+### Repo Trust Score
+
+Measures the contributor's relationship with the **current repository**.
+
+> **Special case:** The repository owner always receives **S / 100**.
+
+| Dimension          | Max | Factors                                                                               |

+| Community Standing | 25  | Account age (0–5), followers (0–10), org membership (+10)                             |
+| OSS Influence      | 20  | Top repo stars (0–15), total stars (0–5)                                              |

-| Reviews       | Number of code reviews given     |
-| Tenure        | Time since first contribution    |
-| Presence      | Public repos and followers       |
+### Profile Score
 
-Contributions carry the most weight; the other four dimensions contribute equally.
+Measures the contributor's **global GitHub profile**, independent of any specific repo.

+### Log Scale
+
+Several Profile Score factors use a logarithmic scale (`logScale(value, ref, max)`) to prevent extreme values from dominating. The `ref` parameter is the reference value that maps to ~70% of the maximum points. For example, `logScale(followers, 200, 12)` means 200 followers ≈ 8.4 points out of 12.

+Profile Score 中多个因子使用对数缩放函数（`logScale(value, ref, max)`），防止极端值主导评分。`ref` 参数为映射到满分 ~70% 的参考值。例如 `logScale(followers, 200, 12)` 表示 200 个关注者 ≈ 8.4 分（满分 12）。
