# BRIEFING — 2026-10-01T22:32:00Z

## Mission
Produce and verify all CRITICAL priority animation atlases (12 mobs + 2 bosses), 15 skill animation atlases (5 classes x 3 skills with Ngũ Hành palettes), and combat VFX (hit impact, death dissolve, damage numbers) with 100% 2^n dimensions, tangent-space normal maps (B mean > 128), and size <= 2MB.

## 🔒 My Identity
- Archetype: worker
- Roles: implementer, qa, specialist
- Working directory: c:/Projects/FreeExile/.agents/teamwork/worker_m3_critical_assets/
- Original parent: 57f2e6be-0ed4-44c4-b348-12dbe4c5bd20
- Milestone: M3 Critical Asset Production

## 🔒 Key Constraints
- Integrity Mandate: Genuine implementations only; no cheating or hardcoding fake verification outputs.
- Exclusive Write Ownership:
  - `client/webapp/assets/animations/mob_*`
  - `client/webapp/assets/animations/boss_*`
  - `client/webapp/assets/skills/skill_*`
  - `client/webapp/assets/savage_vfx/combat_*`
  - Helper asset generation script if needed under `tools/asset_pipeline/`
- Power-of-two (2^n) dimensions on ALL textures (e.g. 1024x1024, 1024x512, 512x512, 2048x1024).
- Tangent-space normal maps must have B mean > 128.
- Atlas file size <= 2MB.
- Manifests must be valid JSON matching `char_*_anim_manifest.json` schema.

## Task Summary
- **What to build**:
  1. 14 animation packages (12 mobs + 2 bosses): 1024x1024 PoT albedo atlas, normal map, and manifest JSON across 6 states x 8 directions.
  2. 15 skill animation atlases (5 classes x 3 skills): 512x512 PoT albedo, normal map, manifest with Ngũ Hành palettes.
  3. Combat VFX particles: `combat_hit_impact`, `combat_death_dissolve`, `combat_damage_numbers` (512x512 PoT atlases, normals, manifests).
- **Success criteria**:
  - All textures 100% power-of-two (1024x1024, 512x512).
  - Tangent-space normal maps B mean > 128 (all measured > 240).
  - All atlas files <= 2MB (all measured <= 880KB).
  - Manifests valid JSON with 48/16 frames and complete state maps.
  - Independent verification script and unit tests pass 100%.

## Key Decisions Made
- Used 1024x1024 (2^10) resolution for mob/boss atlases with 8x8 grid (128x128 frames) to fix existing non-PoT (1280x480) legacy issues and support 6 core states x 8 directions.
- Retained legacy animation state aliases (`run` -> `walk`, `hurt` -> `stun`, `death` -> `die`) in manifests to prevent breaking existing engine runtimes.
- Used 512x512 (2^9) resolution for 15 skill VFX packages with 4x4 grid (128x128 frames: cast, travel, impact, dissolve) mapping strictly to Ngũ Hành element palettes.
- Kept all newly authored scripts <= 350 lines (soft cap compliance).
