ProgressGuard

ProgressGuard gates Valheim's post-boss ambient roamers and random raids 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 and managed random raids. Known managed creatures already present outside their native biome are removed when above that ceiling.

Event Monuments of Torment are blocked and cleaned up outside the Ashlands by default. In the Ashlands, the Monument-of-Torment raid and its monuments are always allowed regardless of online progression.

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. Version 0.1.1 also corrects dedicated-server character resolution so existing ZenBossStone progression imports and online safety tiers are recorded accurately.
