 - Campaign, system, station JSON schemas for hierarchical content validation
 
 ### Fixed
+- Test suite aligned with server v4 protocol enforcement — all hand-built snapshots include version field, verb priorities 1-indexed, ExamineNpc label corrected to "Observe"
+- E2E proof tests resilient to entity ordering — player found by kind instead of array position, wall-hides test checks specific NPC position instead of total count, supports 3-NPC proof room layout
 - Wire entity_id now uses StableId consistently across observer, observation, interpretation, and interaction systems (was Entity::to_bits() in some paths)
 - Restored system/station/district hierarchical fields in district metadata (incorrectly removed during canonical_id cleanup)
 - Unregistered entities in observer/interaction now log tracing::error instead of silently falling back to Entity::to_bits()
