extended initiative_mode enum to manual, dex_based, side, popcorn. Migration adds side_phase string column. dex_based auto-rolls on start_encounter! from linked character’s DEX attribute (rand 1-20 + DEX mod); non-linked tokens default to 10. side groups party vs enemies; next_turn! toggles side_phase. popcorn accepts next_token_id: kwarg; encounter view shows “Pass to…” picker. DM selects mode on stage form. MCP parity: initiative_mode added to create_stage and update_stage tools. _combatant_row partial extracted. 17 new tests, 602 total green. ADR-0066. Custom formula from campaign ruleset deferred.
