### Summary
Implements intelligent MIRV usage for fakehuman players, enabling them
to make strategic nuclear strikes based on game state analysis.
 
### Changes

#### Core FakeHuman Strategy (`FakeHumanExecution.ts`)
- **MIRV Decision System**: Added `considerMIRV()` method that evaluates
game state and determines optimal MIRV usage
- **Three Strategic Targeting Modes**:
1. **Counter-MIRV**: Retaliatory strikes against players actively
launching MIRVs at the fakehuman
2. **Victory Denial**: Preemptive strikes against players approaching
win conditions
     - Team threshold: n% of total land (configurable)
     - Individual threshold: n% of total land (configurable)
3. **Steamroll Prevention**: Strikes against players with dominant city
counts (n% ahead of next competitor)

#### FakeHuman Behavior Tuning
- **Cooldown System**: n-minute cooldown between MIRV attempts
(configurable)
- **Failure Rate**: ~n% chance of cooldown trigger without launch
(simulates human hesitation/resource management; configurable)
- **Territory Targeting**: Centers MIRV strikes on enemy territory
center-of-mass for maximum impact

#### Technical Improvements
- **Type Safety**: Updated `UnitParamsMap` to include `targetTile`
parameter for MIRV units
- **Execution Flow**: Integrated MIRV consideration into fakehuman tick
cycle outside of standard attack logic, due to its holistic strategic
nature

### Game Balance Impact
- **FakeHuman Threat Level**: Increases late-game fakehuman
competitiveness
- **Endgame Dynamics**: Prevents runaway victories, extends game tension

### Breaking Changes
None - purely additive feature

Project Governance

  • The project maintainer (evan) has final authority on all code changes and design decisions
  • All pull requests require maintainer approval before merging
  • The maintainer reserves the right to reject contributions that don't align with the project's vision or quality standards

Contribution Path for New Contributors

To ensure code quality and project stability, we use a progressive contribution system:

  1. New Contributors: Limited to UI improvements and small bug fixes only

    • This helps you become familiar with the codebase
    • UI changes are easier to review and less likely to break core functionality
    • Small, focused PRs have a higher chance of being accepted
  2. Established Contributors: After several successful PRs and demonstrating understanding of the codebase, you may work on more complex features

  3. Core Contributors: Only those with extensive experience with the project may modify critical game systems

How to Contribute Successfully

  1. Before Starting Work:

    • Open an issue describing what you want to contribute
    • Wait for maintainer feedback before investing significant time
    • Small improvements can proceed directly to PR stage
  2. Code Quality Requirements:

    • All code must be well-commented and follow existing style patterns
    • New features should not break existing functionality
    • Code should be thoroughly tested before submission
    • All code changes in src/core MUST be tested.
  3. Pull Request Process:

    • Keep PRs focused on a single feature or bug fix
    • Include screenshots for UI changes
    • Describe what testing you've performed
    • Be responsive to feedback and requested changes
  4. Testing Requirements:

    • Verify your changes work as expected
    • Test on multiple systems/browsers if applicable
    • Document your testing process in the PR

Communication

  • Be respectful and constructive in all project interactions
  • Questions are welcome, but please search existing issues first
  • For major changes, discuss in an issue before starting work

Final Notes

Remember that maintaining this project requires significant effort. The maintainer appreciates your contributions but must prioritize long-term project health and stability. Not all contributions will be accepted, and that's okay.

Thank you for helping make OpenFront better!
