Task Objective:
Empirically stress-test combat engine integration, hooks, and latency performance:
1. Write a standalone empirical challenge harness `challenge_combat_progression.py` in your working directory to challenge:
   - Fatal Damage Dispatch: trigger combat damage resolution where defender HP drops to 0. Verify `DamageEventResult.is_fatal == True`.
   - Callback Invocation: register fatal callback and verify it receives correct victim/killer actor data.
   - Progression Service Hook: attach `LevelProgressionService` via `attach_progression_service` and verify player death penalty is triggered when player dies, and monster defeat awards EXP to killer player.
   - Latency Performance & SLA: benchmark 1,000 fatal combat calculations. Verify execution time per tick is well within the 25ms SLA budget (< 5ms average).
   - Multi-Player Isolation: simulate 10 concurrent player IDs. Verify no crosstalk or state leakage across player instances.
2. Run your challenge script and report empirical output.
3. State verdict: APPROVE or REQUEST_CHANGES in `handoff.md`. Notify parent via `send_message`.
