Changelog

Version 2.4.0 - Dynamic Difficulty Adjustment

Features:
  - Added Dynamic Difficulty Multiplier (DDM) system that adapts wave difficulty based on base defense and infrastructure strength
  - Defense assessment analyzes turret count, density, coverage, and defense layers
  - Infrastructure assessment analyzes production capacity, logistics, and base complexity
  - DDM adjusts wave sizes (0.5x - 2.0x) and cooldowns dynamically
  - Smooth adaptation prevents sudden difficulty jumps
  - Cached calculations for optimal performance (<0.1% UPS impact, <20 KB memory)

New Commands:
  - /smart-ai ddm - View DDM analysis for all discovered bases
  - /smart-ai ddm-sensitivity <0.0-1.0> - Adjust DDM sensitivity
  - /smart-ai ddm-toggle - Toggle DDM on/off

Changes:
  - Wave sizes now adapt to player's defensive capabilities
  - Stronger bases face larger, more frequent waves
  - Weaker bases face smaller, less frequent waves
  - DDM works alongside existing evolution-based scaling and difficulty presets
  - All calculations cached for 30 seconds to maintain performance

Performance:
  - DDM calculations: <1ms per base (cached every 30s)
  - Total UPS impact: <0.1% (well under 1% target)
  - Memory usage: ~15 KB (under 20 KB target)
  - Network impact: None (server-side only)

Version 2.3.1 - Wave Size Fix

Fixes:
  - Increased unit search cap so late-game waves can collect hundreds of units again (previous cap limited to ~150, causing weak waves)

Version 2.3.0 - Adaptive Pressure Layer

Features:
  - Added harassment raids that trigger after bases are discovered (5+ minute cooldown, evolution >= 0.35)
  - Added retaliation strikes when players destroy enemy spawners or worms
  - Shared attack ordering helper to keep groups together even if Factorio unit group creation fails

Changes:
  - Extended unit-group creation to use real Factorio groups for harassment/retaliation for better pathing
  - Updated docs and info.json description
