# BRIEFING — 2026-10-04T12:30:00Z

## Mission
Author TEST_INFRA.md, implement comprehensive E2E test suite in tests/e2e_cocos/test_vfx_texture_atlas_pipeline_e2e.py, execute tests, and deliver TEST_READY.md.

## 🔒 My Identity
- Archetype: test_writer
- Roles: specialist, qa
- Working directory: c:\Projects\FreeExile\.agents\teamwork\test_writer_e2e
- Original parent: 34037784-62e1-41f8-bfe6-912696fdec14
- Milestone: PBR PoT VFX Atlas & Cocos 3.8 / Apple Metal Pipeline E2E Testing

## 🔒 Key Constraints
- Exclusive write ownership:
  - tests/e2e_cocos/test_vfx_texture_atlas_pipeline_e2e.py
  - TEST_INFRA.md (at project root c:\Projects\FreeExile\TEST_INFRA.md)
  - TEST_READY.md (at project root c:\Projects\FreeExile\TEST_READY.md)
  - .agents/teamwork/test_writer_e2e/*
- Write test code and test doc only — never implementation code. Escalate implementation bugs.
- Do NOT place test files in .agents/teamwork/.
- Follow 4-tier testing methodology (Tier 1: Feature Coverage, Tier 2: Boundary & Corner Cases, Tier 3: Cross-Feature Combinations, Tier 4: Real-World Workload Scenarios).

## Task Summary
- **What to build**: Comprehensive 4-tier E2E test suite covering PBR PoT VFX Atlas, Albedo + Tangent Normal maps, ASTC texture generation, UV/dilation boundary validation, manifest consistency (Cocos & WebApp), Skill/Sigil cross-combinations, combat loadout animation sequence simulations, and Cocos TypeScript compilation.
- **Success criteria**: TEST_INFRA.md published; test_vfx_texture_atlas_pipeline_e2e.py authored and executed via pytest; TEST_READY.md published; handoff.md created.
- **Interface contracts**: c:\Projects\FreeExile\.agents\teamwork\orchestrator_22\PROJECT.md
- **Code layout**: tests/e2e_cocos/

## Loaded Skills
- None loaded.

## Quality Status
- **Build/test result**: pytest execution: 20 collected, 9 passed, 11 failed (expected TDD baseline isolating 4 implementation defects).
- **TypeScript compilation**: Cocos `npm run build:web` passes cleanly (exit code 0).
- **Tests added/modified**: `tests/e2e_cocos/test_vfx_texture_atlas_pipeline_e2e.py` (20 tests covering Tiers 1-4).

## Key Decisions Made
- Derived all expected values from authoritative sources (`ORIGINAL_REQUEST.md`, `PROJECT.md`, `FE-SURVEY-SKILLS-VFX-20261004`, `SURVEY-20261004-ASSET-PIPELINE-TEXTURES`).
- Implemented robust multi-key identifier matching for skills/sigils supporting numeric IDs, canonical keys, and English/Vietnamese aliases.
- Isolated 4 clear implementation defects in TEST_READY.md: GAP-01 (missing 8 skills and 3 sigils), GAP-02 (OpenCV BGR channel order bug in normal map baker), GAP-03 (insufficient dilation padding on boundary fringe), GAP-04 (missing ASTC container).
