• Imported saves are now stored in IndexedDB instead of localStorage, so large saves no longer hit the browser's localStorage limit. Saves for every mod move over automatically on first load, and each one stays in localStorage until the move succeeds
• New Manage → Export for Agents: a small export of one game for AI agents and scripts, with only the planets you pick and no password. Create from JSON and Replace from JSON load it back
• Create from JSON makes the new game active, and the Combat Sim stack list now follows the active game without a reload
• Combat sim batches are about 60× faster
• Combat sim attack and defense numbers now follow the game's formula, and the Unit Stats card multiplies its bonuses (experience also scales psy defense)
• Combat sim fixes: terrain agility goes to the defender only, from the map hex's terrain; withdrawal adds the sect routing bonus; promotions no longer carry over between batch runs; the Eye of the Prophet only boosts weapons a unit has; attacks stopped by a shield count as unresolved
• Combat sim warns about stacks EFS would not allow: house and ministry units mixed, relics in a ministry stack, and attackers that cannot move
• Combat sim stack imports set the Vau or Symbiot trait, known techs and relics. Batch results count wins, losses and unresolved runs with per-slot outcomes, and can be downloaded as JSON
• Agent guide for AI agents at /techgraph/skill.md, and a new AI Agent button with a ready-made prompt to copy into your agent
