BaseCreatures are deleted on death (Mobile.OnDeath calls Delete for non-players), so after save/restart the corpse's _owner reference resolves to null. CorpseNotoriety gated its entire creature branch on `target.Owner is BaseCreature`, falling through to player-corpse logic once the reference vanished. That made monster corpses turn red (body.IsMonster -> Murderer) and innocent NPC corpses turn grey (null is not PlayerMobile -> CanBeAttacked) on the next restart.
Snapshots the relevant owner state into CorpseFlag at corpse creation: OwnerWasBaseCreature, OwnerWasSummoned, OwnerWasAnimatedDead. Folds the standalone _murderer bool into CorpseFlag.Murderer for consistency with Criminal. CorpseNotoriety now consults the flags so the creature branch stays correct without a live mobile reference.
Bumps Corpse serialization to v16 with a MigrateFrom(V15Content) that maps the old Murderer bool onto the new flag. Pre-fix corpses already on disk decay within 7 minutes; their first post-restart color may be wrong, which is acceptable.
Also documents that the schema generator must be run after every version bump (`dotnet tool run ModernUOSchemaGenerator -- ModernUO.slnx`) since `dotnet build` does not emit migration JSON files.
Summary
- Adds CLAUDE.md at repo root with 14 terse code audit rules (always loaded, low token cost)
- Adds pointer files for other AI tools: AGENTS.md (Codex), GEMINI.md, .github/COPILOT-INSTRUCTIONS.md (Copilot), .cursorrules (Cursor) — all redirect to CLAUDE.md as single source of truth
- Gitignores /.claude so personal AI config isn't distributed
- Moves Claude skills to dev-docs/claude-skills/ (opt-in, not auto-loaded)
- Adds 14 dev-docs covering codebase conventions
Code Audit Rules (in CLAUDE.md)
1. LINQ tiered rules (Tier 1 free, Tier 2 warm, Tier 3 forbidden)
2. No Console.WriteLine — use LogFactory.GetLogger()
3. No concurrency primitives in game code
4. No World.Mobiles/World.Items iteration
5. Clean up refs in OnDelete()/OnAfterDelete()
6. Cancel timers in OnDelete()/OnAfterDelete()
7. STArrayPool<T>.Shared not ArrayPool<T>.Shared
8. PooledRefList<T> not new List<T>() on hot paths
9. Serialization: partial class, [Constructible], no serialized TimerExecutionToken
10. No Task.Run/new Thread() in game code
11. Never assume era — ask which expansion
12. _camelCase fields, PascalCase properties/methods
13. No empty gumps — use DisplayTo() pattern
14. PropertyList string literals must be {} holes, cliloc-as-argument uses :#
