Your working directory is: c:\Projects\FreeExile\.agents\teamwork\explorer_m4_2_gen2
Your parent is: af73d9ec-d3ff-4501-b986-47b632c5d073 (via orchestrator_1 at c:\Projects\FreeExile\.agents\teamwork\orchestrator_1).

MANDATORY FIRST STEPS:
1. Read the authoritative user request at:
   c:\Projects\FreeExile\.agents\teamwork\ORIGINAL_REQUEST.md
2. Read the project specification at:
   c:\Projects\FreeExile\PROJECT.md
3. Read the E2E test infra and test suite:
   c:\Projects\FreeExile\TEST_INFRA.md
   c:\Projects\FreeExile\tests\e2e\test_poe2_zone_and_encounter_e2e.py
4. Read explorer_m4_3's handoff report for Poise and Leashing context:
   `c:\Projects\FreeExile\.agents\teamwork\explorer_m4_3\handoff.md`

Scope and Task:
Milestone 4: Visceral Telegraphing, Evasion i-Frame & Leashing.
Investigate player dodge roll (Huyễn Ảnh Bộ) and evasion synchronization with incoming monster attacks:
1. Review requirement ORIGINAL_REQUEST.md § R3 & Acceptance Criteria:
   - "Equip elite monsters and bosses with visible attack telegraph cones/rings and windup delays, enabling players to execute Huyễn Ảnh Bộ (0.25s i-frame dodge roll) to evade lethal strikes."
   - "Player dodge roll (Huyễn Ảnh Bộ) provides invulnerability frames (i-frames) against monster attacks during the dodge window."
2. Inspect `client/webapp/js/engine/combat_skills.js`:
   - Inspect dodge roll execution (`player.isIFrame = true; player.iFrameTimer = 0.25;`).
   - Check cooldown gating and phantom trail integration.
   - Line count check: `combat_skills.js` is currently 489 lines (Hard Cap 500 lines!). Any changes must be ultra-compact (<= 5-8 lines).
3. Inspect `client/webapp/js/engine/monster_system.js`:
   - Inspect `executeMonsterAttackOnPlayer` or monster attack damage calculation.
   - When monster attack lands: check `if (player.isIFrame === true || (player.iFrameTimer && player.iFrameTimer > 0))`:
     * Negate damage (damage = 0).
     * Spawn floating combat text: "NÉ ĐÒN! (i-frame)" in cyan/white `#38bdf8`.
     * Play evasion sound/vfx if available.
   - Line count check: `monster_system.js` is currently 496 lines (Hard Cap 500 lines!). Coordinate with explorer_m4_3's line-trimming refactoring to ensure `monster_system.js` stays strictly under 500 lines (target ~470 lines).
4. Inspect server-side combat engine:
   - Inspect `server/world/combat_engine.py`: see how `trigger_phantom_evasion` and `calculate_damage` handle `is_evaded` and 250ms window.
   - Verify that server and client models are 100% aligned.
5. Formulate concrete code recommendations, diffs/patches, and unit test designs for the downstream Worker. Do NOT write source code directly.
6. Write your detailed technical report to:
   c:\Projects\FreeExile\.agents\teamwork\explorer_m4_2_gen2\handoff.md
7. Update `progress.md` in your working directory and notify orchestrator_1 via `send_message` when done.
