## Duplicate Consolidations

### 1. Reference Materials (1 file)
| File | Archived From | Canonical Location |
|------|---------------|-------------------|
| `在非原生ESIM设备上申请Giffgaff ESIM.md` | `100-project/Personal/Phone/` | `200-area/Lifestyle/Mobile/` |

**Rationale:** Reference guide belongs in Area (ongoing reference) not Project (temporary work)

| `DNS.md` | `100-project/Personal/VPS/` | `100-project/Infrastructure/VPS/` |

**Rationale:** Consolidated infrastructure documentation in dedicated Infrastructure project folders

### 3. Resource Templates & Documentation (5 files)
| File | Archived From | Canonical Location |

| `2025.md` (resume) | `200-area/Career/` | `100-project/Personal/resume/` |

**Rationale:** Keep files in more specific subfolders for better organization

---

### 4. Security-Sensitive Files (3 files DELETED)
| File | Deleted From | Canonical Location |
|------|--------------|-------------------|
| `Apple App Password.md` | `300-resources/` | `400-archive/security-sensitive/` |
| `Cookies.md` | `300-resources/Network/` | `400-archive/security-sensitive/` |
| `Domains.md` | `300-resources/Network/` | `400-archive/security-sensitive/` |
