+
+## Core Concepts
+
+### What is a Prefab?
+
+In Unity, a **prefab** is a reusable template that can be instantiated multiple times in scenes. Think of it like a blueprint:
+- A prefab file (`.prefab`) contains GameObjects and Components as YAML
+- When placed in a scene, Unity creates an **instance** of that prefab
+- Each instance can have **modifications** (overrides) applied to it
+
+### What is a Nested Prefab?
+
+A **nested prefab** is a prefab that contains instances of other prefabs within it. For example:
+- `Player.prefab` might contain a nested `Weapon.prefab`
+- When you instantiate `Player.prefab`, it must also instantiate `Weapon.prefab`
+- This can go multiple levels deep
+
+### Key Design Decision: Why Raw YAML?
+
+Prefabs are stored as **raw YAML documents** (`UnityPrefab`) rather than fully-parsed ECS worlds (`UnityScene`). This is because:
+
+1. **Efficient Cloning**: Prefabs need to be instantiated multiple times with different values
+2. **YAML Overrides**: Unity stores modifications as YAML property path overrides (e.g., `m_LocalPosition.x = 100`)
+3. **FileID Remapping**: Each instance needs unique FileIDs to avoid collisions
+
+Scenes, on the other hand, are parsed directly into Sparsey ECS worlds since they don't need cloning.
+
+---
+
+## Prefab Representation
+
+### UnityPrefab Structure
+
+From `unity-parser/src/model/mod.rs:93-146`:
+
+```rust
+pub struct UnityPrefab {
+    /// Path to the prefab file
+    pub path: PathBuf,
+
+    /// Raw YAML documents that make up this prefab
+    pub documents: Vec<RawDocument>,
+}
+```
+
+Each `RawDocument` contains:
+- `type_id`: Unity type ID (e.g., 1 = GameObject, 4 = Transform)
+- `file_id`: Unique identifier within the file
+- `class_name`: The Unity class (e.g., "GameObject", "Transform", "MonoBehaviour")
+- `yaml`: The raw YAML content as serde_yaml::Value
+
+### Loading a Prefab
+
+When you call `UnityFile::from_path("Player.prefab")`, the parser:
+
+1. Reads the file content
+2. Validates the Unity YAML header
+3. Splits the YAML into separate documents (by `--- !u!N &ID` separators)
+4. Creates `RawDocument` objects with metadata extracted
+5. Returns `UnityFile::Prefab(UnityPrefab { path, documents })`
+
+**Important**: At this stage, NO ECS world is created. The prefab stays as raw YAML.
+
+---
+
+## Simple Prefab Instantiation
+
+### Step-by-Step Process
+
+Let's walk through instantiating a simple prefab (no nesting):
+
+#### 1. Create a PrefabInstance
+
+From `unity-parser/src/types/unity_types/prefab_instance.rs:49-70`:
+
+```rust
+let prefab = UnityFile::from_path("Player.prefab")?;
+let mut instance = prefab.instantiate();
+```
+
+`instantiate()` calls `PrefabInstance::new()` which:
+- Clones all documents from the source prefab
+- Initializes FileID remapping (creates new unique IDs)
+- Remaps all FileID references in the YAML
+
+#### 2. Apply Overrides (Optional)
+
+You can modify the prefab before spawning:
+
+```rust
+instance.override_value(file_id, "m_Name", "Player1".into())?;
+instance.override_value(file_id, "m_LocalPosition.x", 100.0.into())?;
+```
+
+This stores overrides in a HashMap that will be applied before spawning.
+
+#### 3. Spawn into ECS World
+
+```rust
+let entities = instance.spawn_into(&mut world, &mut entity_map, guid_resolver, prefab_resolver)?;
+```
+
+`spawn_into()` (`prefab_instance.rs:291-309`):
+1. Applies all stored overrides to the YAML
+2. Calls `build_world_from_documents_into()` to create entities
+3. Returns a Vec of spawned entities
+
+### The Spawning Process
+
+`build_world_from_documents_into()` from `unity-parser/src/ecs/builder.rs:160-265`:
+
+**Pass 1**: Create entities for GameObjects
+- Iterates through documents with `type_id == 1` (GameObject)
+- Spawns ECS entities with `GameObject` component
+- Adds to entity_map (FileID → Entity)
+
+**Pass 2**: Attach components
+- Iterates through remaining documents (Transform, RectTransform, MonoBehaviour, etc.)
+- Looks up `m_GameObject` reference to find owner entity
+- Parses and attaches component to entity
+
+**Pass 3**: Execute deferred linking
+- Resolves Transform parent/child relationships
+- Converts FileID references to Entity handles
+
+---
+
+## Nested Prefab System
+
+### How Unity Represents Nested Prefabs
+
+When you place a prefab inside another prefab in Unity, it creates a **PrefabInstance** document:
+
+```yaml
+--- !u!1001 &1234567890
+PrefabInstance:
+  m_SourcePrefab: {fileID: 0, guid: "091c537484687e9419460cdcd7038234", type: 3}
+  m_Modification:
+    - target: {fileID: 5678}
+      propertyPath: m_Name
+      value: "ModifiedName"
+    - target: {fileID: 5679}
+      propertyPath: m_LocalPosition.x
+      value: 10.5
+```
+
+### PrefabInstanceComponent
+
+From `unity-parser/src/types/unity_types/prefab_instance.rs:322-366`:
+
+```rust
+pub struct PrefabInstanceComponent {
+    /// External reference to the source prefab (by GUID)
+    pub prefab_ref: ExternalRef,  // Contains GUID string
+
+    /// Modifications applied to the nested prefab
+    pub modifications: Vec<PrefabModification>,
+}
+
+pub struct PrefabModification {
+    pub target_file_id: FileID,      // Which object to modify
+    pub property_path: String,        // Dot notation: "m_Name", "m_LocalPosition.x"
+    pub value: Value,                 // The new value
+}
+```
+
+### GUID Resolution
+
+Before we can instantiate a nested prefab, we need to resolve its GUID to a file path.
+
+**PrefabGuidResolver** (`unity-parser/src/parser/prefab_guid_resolver.rs`):
+
+1. **Initialization**: Scans Unity project directory for `.prefab.meta` files
+2. **GUID Extraction**: Parses each `.meta` file to get the GUID
+3. **Mapping**: Builds a HashMap: `Guid → PathBuf`
+
+Example:
+```
+Assets/Prefabs/Player.prefab.meta contains:
+guid: 091c537484687e9419460cdcd7038234
+
+→ Maps: 0x091c537484687e9419460cdcd7038234 → "Assets/Prefabs/Player.prefab"
+```
+
+### PrefabResolver
+
+**PrefabResolver** (`prefab_instance.rs:430-706`) handles loading and recursive instantiation:
+
+```rust
+pub struct PrefabResolver<'a> {
+    /// Cache of loaded prefabs (GUID → Prefab)
+    prefab_cache: HashMap<String, Arc<UnityPrefab>>,
+
+    /// Mapping from GUID to file path
+    guid_to_path: HashMap<String, PathBuf>,
+
+    /// Stack for circular reference detection
+    instantiation_stack: Vec<String>,
+
+    /// GUID resolver for MonoBehaviour scripts
+    guid_resolver: Option<&'a GuidResolver>,
+
+    /// Prefab GUID resolver
+    prefab_guid_resolver: Option<&'a PrefabGuidResolver>,
+}
+```
+
+### Nested Prefab Instantiation Flow
+
+From `prefab_instance.rs:496-572` - `instantiate_from_component()`:
+
+```
+PrefabInstanceComponent found in scene
+         ↓
+1. Extract GUID from component.prefab_ref
+         ↓
+2. Load prefab via GUID resolver: GUID → Path → UnityPrefab
+         ↓
+3. Create PrefabInstance (clone + remap FileIDs)
+         ↓
+4. Apply modifications from component.modifications
+         ↓
+5. Spawn prefab into world (creates entities)
+         ↓
+6. Link spawned root to parent entity (if provided)
+         ↓
+Returns: Vec<Entity> of spawned entities
+```
+
+### Recursive Nested Prefabs
+
+For deeply nested prefabs (prefabs containing prefabs containing prefabs...):
+
+**instantiate_recursive()** (`prefab_instance.rs:574-643`):
+
+```
+Start with root prefab
+         ↓
+1. Check for circular references (using instantiation_stack)
+         ↓
+2. Push prefab ID to stack
+         ↓
+3. Create PrefabInstance
+         ↓
+4. Scan documents for nested PrefabInstance components
+         ↓
+5. For each nested prefab:
+   - Load the referenced prefab by GUID
+   - Apply its modifications
+   - Recursively call instantiate_recursive()
+         ↓
+6. Spawn this prefab's entities
+         ↓
+7. Pop from stack
+```
+
+This handles arbitrary nesting depth while preventing infinite loops from circular references.
+
+---
+
+## The 4-Pass ECS Building Process
+
+When parsing a Unity scene, the ECS builder uses a multi-pass approach to handle prefabs.
+
+From `unity-parser/src/ecs/builder.rs:31-138`:
+
+### Pass 1: Create GameObject Entities
+
+```rust
+for doc in documents.iter().filter(|d| d.type_id == 1 || d.class_name == "GameObject") {
+    let entity = spawn_game_object(&mut world, doc)?;
+    entity_map.insert(doc.file_id, entity);
+}
+
+// Also create entities for PrefabInstances
+for doc in documents.iter().filter(|d| d.type_id == 1001 || d.class_name == "PrefabInstance") {
+    let entity = world.create(());
+    entity_map.insert(doc.file_id, entity);
+
+    // Parse and attach PrefabInstanceComponent
+    if let Some(prefab_comp) = PrefabInstanceComponent::parse(yaml, &ctx) {
+        world.insert(entity, (prefab_comp,));
+    }
+}
+```
+
+At this stage:
+- All GameObjects → Entities
+- All PrefabInstances → Entities with `PrefabInstanceComponent` attached
+- entity_map tracks FileID → Entity
+
+### Pass 2: Attach Components
+
+```rust
+for doc in documents.iter().filter(|d| d.type_id != 1 && d.class_name != "GameObject") {
+    attach_component(&mut world, doc, &linking_ctx, &type_filter, guid_resolver)?;
+}
+```
+
+- Parses Transform, RectTransform, MonoBehaviour, etc.
+- Looks up `m_GameObject` reference to find owner entity
+- Attaches parsed component to entity
+
+### Pass 2.5: Resolve Prefab Instances (NEW!)
+
+This is where the magic happens for nested prefabs (`builder.rs:92-132`):
+
+```rust
+if let Some(prefab_resolver_ref) = prefab_guid_resolver {
+    let mut prefab_resolver = PrefabResolver::from_resolvers(guid_resolver, prefab_resolver_ref);
+
+    // Query for entities with PrefabInstanceComponent
+    let prefab_entities: Vec<_> = world.query::<&PrefabInstanceComponent>().collect();
+
+    for (entity, component) in prefab_entities {
+        // Instantiate the referenced prefab
+        match prefab_resolver.instantiate_from_component(
+            &component,
+            Some(entity),  // Parent entity
+            &mut world,
+            &mut entity_map,
+        ) {
+            Ok(spawned) => {
+                info!("Spawned {} entities from prefab", spawned.len());
+            }
+            Err(e) => {
+                warn!("Failed to instantiate prefab: {}", e);
+            }
+        }
+
+        // Remove PrefabInstanceComponent after resolution
+        world.remove::<(PrefabInstanceComponent,)>(entity);
+    }
+}
+```
+
+**Key Points**:
+1. Only runs if a PrefabGuidResolver is provided
+2. Finds all entities with `PrefabInstanceComponent`
+3. For each one:
+   - Resolves GUID → loads prefab
+   - Creates instance with modifications
+   - Spawns into current world
+   - Links to parent entity
+4. Removes `PrefabInstanceComponent` (no longer needed)
+
+### Pass 3: Execute Deferred Linking
+
+```rust
+let entity_map = linking_ctx.execute_callbacks(&mut world);
+```
+
+- Resolves Transform parent/child relationships
+- Converts FileID references to actual Entity handles
+- This happens AFTER prefab instantiation so that prefab entities are in the map
+
+---
+
+## FileID Remapping
+
+### Why Remap FileIDs?
+
+Unity FileIDs are unique within a single file, but when instantiating multiple prefab instances, we need to ensure no collisions:
+
+```
+Scene.unity:
+  GameObject &100  ← FileID = 100
+  Transform &101   ← FileID = 101
+
+Player.prefab (first instance):
+  GameObject &100  ← COLLISION!
+  Transform &200
+
+Player.prefab (second instance):
+  GameObject &100  ← COLLISION!
+  Transform &200
+```
+
+### The Solution
+
+From `prefab_instance.rs:72-114`:
+
+**Step 1**: Generate unique IDs for each document
+
+```rust
+fn generate_file_id(&mut self) -> FileID {
+    let id = self.next_file_id;  // Starts at i64::MAX
+    self.next_file_id -= 1;      // Decrement
+    FileID::from_i64(id)
+}
+```
+
+- Uses i64::MAX and decrements: `9223372036854775807`, `9223372036854775806`, ...
+- Scene FileIDs are typically small positive numbers (1, 100, 1000)
+- This avoids collisions
+
+**Step 2**: Build mapping table
+
+```rust
+fn initialize_file_id_mapping(&mut self) {
+    for original_id in original_ids {
+        let new_id = self.generate_file_id();
+        self.file_id_map.insert(original_id, new_id);
+    }
+}
+```
+
+Example mapping:
+```
+Original → New
+100      → 9223372036854775807
+200      → 9223372036854775806
+```
+
+**Step 3**: Remap all references
+
+```rust
+fn remap_yaml_file_refs(&mut self) {
+    // Update document's own FileID
+    for doc in &mut self.documents {
+        doc.file_id = self.file_id_map[&doc.file_id];
+    }
+
+    // Update all FileRef references in YAML: {fileID: N}
+    for doc in &mut self.documents {
+        Self::remap_value(&mut doc.yaml, &file_id_map);
+    }
+}
+```
+
+This recursively walks the YAML tree and replaces all `{fileID: 100}` with `{fileID: 9223372036854775807}`.
+
+### Handling Overrides
+
+When applying overrides before spawning:
+
+```rust
+instance.override_value(original_file_id, "m_Name", "Player1".into())?;
+```
+
+The API accepts the **original** FileID for convenience, but internally:
+
+```rust
+fn apply_overrides(&mut self) -> Result<()> {
+    for ((file_id, path), value) in &self.overrides {
+        // Map original FileID → remapped FileID
+        let remapped_id = self.file_id_map.get(file_id)?;
+
+        // Find document with remapped ID
+        let doc = self.documents.iter_mut()
+            .find(|d| d.file_id == *remapped_id)?;
+
+        // Apply value change
+        set_yaml_value(&mut doc.yaml, path, value)?;
+    }
+}
+```
+
+---
+
+## Code Examples
+
+### Example 1: Manual Prefab Instantiation
+
+```rust
+use unity_parser::{UnityFile, UnityPrefab};
+use sparsey::World;
+use std::collections::HashMap;
+
+fn main() -> Result<(), Box<dyn std::error::Error>> {
+    // Load prefab
+    let file = UnityFile::from_path("Assets/Prefabs/Player.prefab")?;
+    let prefab = match file {
+        UnityFile::Prefab(p) => p,
+        _ => panic!("Expected prefab"),
+    };
+
+    // Create instance with modifications
+    let mut instance = prefab.instantiate();
+    instance.override_value(file_id, "m_Name", "Player1".into())?;
+    instance.override_value(file_id, "m_LocalPosition.x", 100.0.into())?;
+
+    // Spawn into world
+    let mut world = World::new();
+    let mut entity_map = HashMap::new();
+    let entities = instance.spawn_into(&mut world, &mut entity_map, None, None)?;
+
+    println!("Spawned {} entities", entities.len());
+    Ok(())
+}
+```
+
+### Example 2: Automatic Scene Parsing with Nested Prefabs
+
+```rust
+use unity_parser::UnityProject;
+
+fn main() -> Result<(), Box<dyn std::error::Error>> {
+    // Initialize project (builds GUID resolvers)
+    let project = UnityProject::from_path("/home/user/UnityProject")?;
+
+    // Parse scene - automatically resolves and instantiates prefabs
+    let scene = project.parse_scene("Assets/Scenes/Level1.unity")?;
+
+    println!("Scene has {} entities", scene.entity_map.len());
+
+    // Query entities
+    let game_objects = scene.world.borrow::<unity_parser::GameObject>();
+    let transforms = scene.world.borrow::<unity_parser::Transform>();
+
+    for (file_id, entity) in &scene.entity_map {
+        if let Some(go) = game_objects.get(*entity) {
+            if let Some(transform) = transforms.get(*entity) {
+                println!("GameObject '{}' at {:?}",
+                    go.name(), transform.local_position());
+            }
+        }
+    }
+
+    Ok(())
+}
+```
+
+### Example 3: Recursive Prefab Loading
+
+```rust
+use unity_parser::{UnityFile, PrefabResolver, PrefabGuidResolver};
+use sparsey::World;
+
+fn main() -> Result<(), Box<dyn std::error::Error>> {
+    // Build prefab GUID resolver
+    let prefab_guid_resolver = PrefabGuidResolver::from_project("UnityProject")?;
+
+    // Create prefab resolver
+    let mut prefab_resolver = PrefabResolver::from_resolvers(None, &prefab_guid_resolver);
+
+    // Load a prefab with nested prefabs
+    let file = UnityFile::from_path("Assets/Prefabs/ComplexPrefab.prefab")?;
+    let prefab = match file {
+        UnityFile::Prefab(p) => p,
+        _ => panic!("Expected prefab"),
+    };
+
+    // Recursively instantiate (handles nested prefabs automatically)
+    let mut world = World::new();
+    let mut entity_map = HashMap::new();
+    let entities = prefab_resolver.instantiate_recursive(
+        &prefab,
+        &mut world,
+        &mut entity_map,
+    )?;
+
+    println!("Recursively spawned {} entities", entities.len());
+    Ok(())
+}
+```
+
+---
+
+## Summary
+
+### Prefab Instantiation Flow
+
+```
+UnityPrefab (raw YAML)
+         ↓
+   instantiate()
+         ↓
+PrefabInstance (cloned YAML with remapped FileIDs)
+         ↓
+override_value() (optional)
+         ↓
+   spawn_into()
+         ↓
+ECS World (Sparsey entities with components)
+```
+
+### Nested Prefab Resolution Flow
+
+```
+Scene contains PrefabInstance document
+         ↓
+Pass 1: Create entity with PrefabInstanceComponent
+         ↓
+Pass 2.5: Find all PrefabInstanceComponent entities
+         ↓
+For each: GUID → Path → Load Prefab
+         ↓
+Create instance + apply modifications
+         ↓
+Recursively check for nested PrefabInstances
+         ↓
+Spawn all entities into world
+         ↓
+Link to parent entity
+```
+
+### Key Takeaways
+
+1. **Prefabs stay as YAML** until instantiation for efficient cloning and overrides
+2. **FileID remapping** prevents collisions when instantiating multiple times
+3. **PrefabGuidResolver** maps GUIDs to file paths for automatic loading
+4. **Pass 2.5** in the ECS builder handles automatic prefab instantiation
+5. **Recursive instantiation** handles arbitrary nesting depth with circular reference detection
+6. **Modifications** are stored as property path + value pairs and applied before spawning

-## Known Issues
-
-### Critical Issues
-1. **`unity-parser/src/project/mod.rs` is OUTDATED**
-   - Built for old architecture before `UnityFile` enum refactor
-   - References non-existent `UnityDocument` type (should be `RawDocument`)
-   - Module is disabled in lib.rs until refactored
-
-2. **Derive macro namespace mismatch**
-   - `unity-parser-macros` uses `unity_parser` namespace
-   - Actual crate name is `unity_parser::` (underscore, not hyphen)
-   - Manual `UnityComponent` implementation recommended
-
-3. **Placeholder values in Cargo.toml**
-   - Author and repository fields need updating
-
-### Minor Issues
-1. Disabled example/test files may reference outdated APIs
-2. Some examples may have incorrect YAML access patterns
-
