Manual QA — NEO-34 (skill catalog at startup)

Prerequisites

Repo clone with content/skills and content/schemas/skill-def.schema.json present.

From server/NeonSprawl.Server, run dotnet run (no extra Content env). Startup logs an Information line from category NeonSprawl.Server.Game.Skills.SkillCatalog with the absolute skills directory path and 3 skills (prototype catalog).
GET /health returns 200 after startup.
Introduce a deliberate catalog error (e.g. temporarily duplicate an id in content/skills/prototype_skills.json). dotnet run fails before listening; stderr shows Skill catalog validation failed and a path/rule hint. Revert the edit after the check.
Optional: set Content__SkillsDirectory to a temp directory with invalid JSON and confirm the same fail-fast behavior.
