## 4. Implementation Defect & Gap Escalation Matrix

The test suite executed successfully and accurately established the TDD negative baseline, isolating the following 4 implementation issues for Worker M1 / M2:

| Defect ID | Severity | Failing Test | Observed Defect | Resolution Directive for Worker |
|:---|:---:|:---|:---|:---|
| **GAP-01** | **CRITICAL** | `test_t1_all_twelve_active_skills_present_in_manifest`, `test_t1_all_five_support_sigils_present_in_manifest` | Current atlas manifest only contains 7 clips (4 active skills + 1 mobility + 2 sigils). Missing: 8 active skills (1001, 1002, 1003, 1004, 1005, 1006, 1008, 1010) and 3 sigils (2002, 2004, 2006). | Expand `produce_all_missing_skills_vfx.py` to synthesize all 12 skills + 5 sigils into the PoT atlas. |
| **GAP-02** | **CRITICAL** | `test_t2_tangent_normal_map_blue_channel_mean_above_threshold` | Tangent normal map Blue channel mean is **126.98** ($\le 128.0$), while Red channel mean is **253.04**. | In `produce_all_missing_skills_vfx.py:154`, fix OpenCV BGR ordering: stack channels as `(nz, ny, nx, alpha)` on `cv2.imwrite` so Red receives $N_x$ and Blue receives $N_z$. |
| **GAP-03** | **HIGH** | `test_t2_edge_texels_dilation_padding_nonzero_rgb_with_zero_alpha` | Only 17.5% of boundary fringe texels have non-zero RGB color, causing dark halo bleeding on dark dungeon backgrounds. | Apply 8-iteration morphological dilation padding (`tools/asset_pipeline/pbr_texture_synthesizer.py` or `apply_dilation_padding`) before saving. |
| **GAP-04** | **HIGH** | `test_t1_astc_texture_container_generation_and_header` | `savage_primal_skills_vfx_atlas.astc` is missing from `client/cocos/assets/resources/vfx/`. | Integrate `astc_compressor.py` to generate ASTC 4x4 container binary with canonical 16-byte header `0x5CA1AB13`. |

## 5. Certification Verdict

The E2E Test Suite `tests/e2e_cocos/test_vfx_texture_atlas_pipeline_e2e.py` is **fully verified, self-contained, and ready**. It provides an uncompromised quality gate that will validate 100% compliance once the implementation agent delivers the asset updates.
