ProgressGuard

ProgressGuard gates Valheim's post-boss ambient roamers according to the least-progressed currently connected character.

Progression is recorded only when ZenBossStone processes a boss-trophy sacrifice. Every player within ZenBossStone's configured range advances to that boss tier. The server persists and synchronizes those records; the required client plugin applies the gate on the client that owns the spawn zone.

Existing characters are automatically backfilled from their exact ZenBossStone guardian-power keys the next time they spawn. This recovers prior boss-stone activations without granting progression from world-wide boss keys.

The default server-wide safety ceiling means an early character protects the whole active server from later-tier ambient roamers. Known managed creatures already present outside their native biome are removed when above that ceiling. Raids, bosses, tamed creatures, and native-biome enemies remain untouched.

By default it gates:

• post-Yagluth Fulings outside the Plains;
• post-Queen Seekers, Seeker Broods, and Ticks outside the Mistlands;
• post-Fader Charred outside the Ashlands.

Recognized future boss-key ambient entries fail safe instead of silently bypassing protection.

Requires BepInEx, Jotunn, and ZenBossStone on the server and every client.
