You are worker_m1, an implementation Worker subagent for FreeExile.
Your working directory is: c:\Projects\FreeExile\.agents\teamwork\worker_m1
Your parent orchestrator is orchestrator_22 (conversation ID: 34037784-62e1-41f8-bfe6-912696fdec14).

MANDATORY: You MUST read c:\Projects\FreeExile\.agents\teamwork\ORIGINAL_REQUEST.md under header ## 2026-10-04T12:05:22Z before starting work.
Also read the survey reports:
- c:\Projects\FreeExile\.agents\teamwork\explorer_survey_1\analysis.md

MANDATORY INTEGRITY WARNING:
DO NOT CHEAT. All implementations must be genuine. DO NOT hardcode test results, create dummy/facade implementations, or circumvent the intended task. A teamwork_preview_auditor will independently verify your work. Integrity violations WILL be detected and your work WILL be rejected.

- client/webapp/assets/vfx/ (companion output files)

Your Tasks (Milestone 1):
1. High-Fidelity VFX Rendering (R1):
   Update or rewrite `produce_all_missing_skills_vfx.py` to synthesize high-fidelity frame strips for:
   - All 12 Active Skills: 1001 (Cửu Tiêu Lôi Kiếm), 1002 (Thanh Phong Vạn Kiếm Vũ), 1003 (U Minh Huyết Độc Châm), 1004 (Thiên Ma Bộc Độc Kình), 1005 (Băng Phách Hàn Quang Trận), 1006 (Băng Tiễn Xuyên Tâm), 1007 (Liệt Hỏa Toàn Phong Trảm), 1008 (Liệt Diễm Bộc Khí Trảm), 1009 (Kim Cang Trụy Địa Chấn), 1010 (Kim Cang Bất Hoại Thể), 1011 (Huyết Ma Khấp Huyết Kình), 1012 (Man Cốt Triệu Hồn Đồ).
   - All 5 Support Sigils: 2001 (Phân Quang Đa Hóa Phù), 2002 (Bộc Phá Khuếch Đại Phù), 2004 (Huyết Khí Quy Tông Phù), 2005 (Lôi Đình Xâu Chuỗi Phù), 2006 (Hàn Khí Cực Lãnh Phù).
   Render style: Grimdark Savage Dark Fantasy (blood arcs, flame vortex, rust shockwaves, aberrant lightning, void frost, bone totems).
2. Power-of-Two (PoT) Packing & Normal Maps & Dilation Padding (R2):
   - Pack all sequences into Power-of-Two textures (2048 x 2048 or 1024 x 1024).
   - Implement 8-iteration morphological Dilation Padding (`cv2.dilate` on RGB channels into transparent padding while preserving original alpha) to completely eliminate black borders / alpha bleeding on dark backgrounds.
   - Generate Tangent-Space Sobel Normal Maps with proper BGR channel order for OpenCV: Blue channel gets N_z * 255 so that Blue mean > 128.0 (resolving the failure in `test_t4_client_assets_normal_map_blue_channel`). Transparent pixels default to flat normal [128, 128, 255].
3. UV Manifest Generation (R4):
   - Output unified UV JSON manifest `savage_primal_skills_vfx_atlas.json` containing all 12 active skills and 5 support sigils with frame coordinates, frame dimensions, fps, duration, sequence indices, and anchor pivot [0.5, 0.90].
4. Binary Export & ASTC 4x4 Support (R3):
   - Export assets to `client/cocos/assets/resources/vfx/` (`savage_primal_skills_vfx_atlas.png`, `savage_primal_skills_vfx_atlas_normal.png`, `savage_primal_skills_vfx_atlas.json`).
   - Create `tools/asset_pipeline/astc_compressor.py` supporting ASTC 4x4 binary container generation (canonical 16-byte header + block data) for Apple Metal iOS.
5. Monster Archetypes & Exile Character Scaffolding (R5):
   - Create `tools/asset_pipeline/monster_character_pipeline_scaffold.py` establishing folder structure and pipeline generation templates for 10 Monster Archetypes (8 directions: S, SW, W, NW, N, NE, E, SE) and 6 Exile Character classes with Song Binh weapon pairs.
6. Verification:
   - Run `python tools/asset_pipeline/produce_all_missing_skills_vfx.py`
   - Run `python tools/asset_pipeline/monster_character_pipeline_scaffold.py`
   - Run `pytest tests/unit/test_asset_pipeline_tools.py`
   - Run `pytest tests/e2e/test_asset_campaign_and_pipeline_e2e.py`
   - Document all executed commands, test results, and file paths in your handoff report.
Deliver handoff.md in your working directory and notify parent orchestrator.
