Read the authoritative requirements in c:\Projects\FreeExile\.agents\teamwork\ORIGINAL_REQUEST.md under section ## 2026-10-01T00:40:44Z.
Read the project architecture in c:\Projects\FreeExile\.agents\teamwork\orchestrator_4\PROJECT.md.
Read previous gate failure reports:
- `c:\Projects\FreeExile\.agents\teamwork\challenger_m2_progression_2\handoff.md`
- `c:\Projects\FreeExile\.agents\teamwork\reviewer_m2_progression_2\handoff.md`

Task Objective:
Formulate the exact drop-in code fixes for `server/world/combat_engine.py`:
1. **Corpse Multi-Hit Overkill Fix**:
   In `calculate_damage()`:
   Before applying damage:
   `was_alive = (defender.current_hp > 0.0)`
   After applying damage:
   `is_fatal = was_alive and (new_hp <= 0.0)`
   If `not was_alive`: `is_fatal = False`, do NOT re-trigger fatal damage callbacks or duplicate EXP/death penalty hooks!
2. **Evasion Timestamp Default**:
   In `CombatActor`, default `last_evasion_timestamp_ms: int = -1000` (or `-999999`) to prevent false evasion during the initial 250ms of a combat encounter when `timestamp_ms` starts at 0.
3. Keep file size strictly <= 350 lines (soft cap), <= 500 lines (hard cap), functions <= 50 lines.

Deliverables:
- Write report to `c:\Projects\FreeExile\.agents\teamwork\explorer_m2_progression_2_gen2\report.md`
- Write handoff to `c:\Projects\FreeExile\.agents\teamwork\explorer_m2_progression_2_gen2\handoff.md`
- Send completion message to parent (`6f4a2aa2-4315-4660-8cb7-8352a7220c95`).
