## Mission
Adversarial stress-testing of Milestone 3 Remediation: Client Script Integration & Leader Aura Ground Decals.

## 🔒 My Identity

## 🔒 Key Constraints
- Review-only — do NOT modify implementation code
- Run empirical tests, do NOT trust claims or logs
- Do not place source code, tests, or data files in .agents/teamwork/

## Review Scope
- **Files to review**: `client/webapp/index.html`, `client/webapp/js/data/wilderness_zone_packs.js`, `client/webapp/js/engine/monster_pack_system.js`, `client/webapp/js/engine/ambush_trigger_system.js`, `client/webapp/js/engine/entity_renderer.js`
- **Interface contracts**: `PROJECT.md`, `ORIGINAL_REQUEST.md`, `worker_m3_2/handoff.md`
- **Review criteria**: DOM script integration, global function presence, CanvasRenderingContext2D rendering and gradient/arc calculations across 5 aura types.

## Attack Surface
- **Hypotheses tested**:
  1. Script tags in `index.html`: presence, `type="module"`, and ordering. -> VERIFIED PASS.
  2. Window global exports (`getWildernessZoneMonsters`, `initZoneAmbushTriggers`, `updateMonsterPackAI`, `updateAmbushTriggers`, `renderLeaderAuraDecal`). -> VERIFIED PASS.
  3. Leader Aura Decal 5 aura types (HASTE, DAMAGE_RESISTANCE, ELEMENTAL_EMPOWERMENT, VAMPIRIC, MORTAL_MIGHT) with mock Canvas 2D context: gradient/stroke/fill, 2 isometric ellipses, finite coordinates, zero NaN, zero throw. -> VERIFIED PASS.
  4. Adversarial edge cases (dead mobs, negative HP, non-leaders, null/undefined/unknown aura types, extreme negative/positive coordinates, non-standard timeSec). -> VERIFIED PASS.
  5. High-frequency 10,000-frame render stress loop (<0.05ms/frame budget, 20,000 ellipses, 0 errors). -> VERIFIED PASS.
  6. Visual layering in `entity_renderer.js`: shadow < leader aura decal < sprite. -> VERIFIED PASS.
  7. Safe Haven firewall: zero mobs spawned in `zone_player_hideout` and `zone_boundless_sanctuary`. -> VERIFIED PASS.
- **Vulnerabilities found**: None in tested remediation scope.
- **Untested angles**: WebGL shader pipeline (out of scope for Canvas 2D decals).

## Loaded Skills
None

## Key Decisions Made
- Authored test suite `tests/unit/test_challenger_m3_script_and_aura_stress.py` (293 lines, under 350 soft cap).
- Executed 5 comprehensive tests covering DOM, Node.js runtime, Canvas mock, 10k frames, and layering.
- Confirmed full remediation stability. Verdict: **APPROVE**.
