## 3. 4-Tier Test Coverage Breakdown

### Tier 1: Functional Feature Coverage (11 Tests)
- `test_t1_drq_inbox_total_and_naming`: Verifies inbox contains $\ge 20$ DRQ files matching `DRQ-20261001-*.md` (actual: 21).
- `test_t1_drq_department_diversity`: Validates $\ge 3$ DRQs across all 6 departments: Systems (SYS), Narrative & NPC (NPC), Economy (ECO), Security (SEC), Client Engine (CLI), and Server & AI (SRV).
- `test_t1_drq_mandatory_metadata_keys`: Enforces presence of mandatory metadata keys across all DRQs.
- `test_t1_drq_resolutions_power_of_two`: Validates $2^n$ power-of-two dimensions in all DRQ metadata headers.
- `test_t1_lod_generator_three_tiers`: Verifies generation of LOD0 (100%), LOD1 (50%), LOD2 (25%) using Lanczos downsampling.
- `test_t1_lod_file_size_reduction`: Proves LOD-2 file size is $\le 40\%$ of original source texture size (achieves $\sim 3\%$).
- `test_t1_webp_compression_api`: Guarantees WebP compression ratio $\le 50\%$ and preserves RGBA alpha transparency (achieves $\sim 95\%$ reduction on sprites).
- `test_t1_webp_batch_directory`: Verifies batch directory compression converting all PNG textures to WebP.
