Protectorate tribute + automatic war entry (P5.3A)
2026-03-25
- Vassal alliances now pay a **per-tick income tribute** (10% by default, configurable 5–20%) to their protector at each tick. The tribute is deducted from each vassal nation's income and credited to the protector's LEADER nation.
- **Automatic war entry**: when a protector is attacked, all vassal alliances auto-enter the war on the protector's side (and vice versa — protector defends vassal). Auto-entry creates a war against the original attacker.
- **Dissolution notice**: a vassal that cancels a PROTECTORATE treaty gives 24-tick advance notice (treaty remains active until then). The protector can dissolve immediately without notice.
- Dissolution notice is published to the world feed as a `TreatyDissolutionNotice` event.
