-## Global vs Player State: Door Examples
-
-> **Filenames are IDs.** Object and room YAML below carry no `id:` field — the filename is the ID (e.g. `door_button.yaml` → `door_button`). A nested `- id:` under a room's `objects:` list is a *reference* and stays.
-
-### Example A: Door with a button in another room (GLOBAL)
-
-A button in room 3 opens a door in room 7. Anyone can press it. Once pressed, the door is open for everyone.
-
-**Button object** (`data/objects/door_button.yaml`):
-```yaml
-name: stone button
-hidden: true
-on_use:
-  - condition:
-      global_flag: secret_door_open
-      not: true
-    message: "You press the stone button. You hear grinding stone in the distance."
-    action:
-      set_global_flags:
-        secret_door_open: true
-```
-
-**Room 3** — contains the button:
-```yaml
-name: "Button Chamber"
-description: "A small stone chamber. A button protrudes from the east wall."
-exits:
-  south: 1
-objects:
-  - id: door_button
-```
-
-**Room 7** — contains the door:
-```yaml
-name: "Hidden Passage"
-description: "A dusty corridor. A heavy stone door blocks the way north."
-exits:
-  south: 2
-  north:
-    room: 8
-    condition:
-      flag: secret_door_open                           # checks WORLD flag
-      value: true
-    blocked_message: "A heavy stone door blocks the way."
-objects:
-  - id: stone_door
-    hidden: true
-```
-
-### Example B: Key-locked door (PLAYER-LOCAL)
-
-A locked door that only opens for a player carrying the key. Each player must find their own key.
-
-**Key item** (`data/items/rusty_key.yaml`):
-```yaml
-name: rusty key
-description: "An old iron key, still functional."
-value: 0
-stackable: false
-```
-
-**Room 5** — locked door:
-```yaml
-name: "Locked Storage"
-description: "A small storage room. The way east is blocked by a locked iron door."
-exits:
-  west: 2
-  east:
-    room: 6
-    condition:
-      has_item: rusty_key                               # checks PLAYER inventory
-    blocked_message: "The iron door is locked. You need a key."
-objects:
-  - id: iron_door
-    hidden: true
-```
-
-**Room 6** — the other side (no key needed to exit):
-```yaml
-name: "Storage Closet"
-description: "Shelves of dusty crates."
-exits:
-  west: 5                                               # exit back — no condition
-spawns:
-  - item_id: uncut_ruby
-    quantity: 1
-    respawn_ticks: 500
-```
-
-Key difference: the button door uses `global_flag` (shared state — one player presses, everyone benefits), the key door uses `has_item` (per-player inventory check — each player needs their own key).
