 Sometimes (for debugging purposes, for example), it is necessary to extract the index and version from an identifier or to pack them back into an identifier. The [`evolved.pack`](#evolvedpack) and [`evolved.unpack`](#evolvedunpack) functions can be used for this purpose.

+#### Entity Location
+
+Sometimes it is useful to know which chunk a specific entity is in and its position within that chunk. The [`evolved.locate`](#evolvedlocate) function provides this information.
+
+```lua
+---@param entity evolved.entity
+---@return evolved.chunk? chunk
+---@return integer place
+function evolved.locate(entity) end
+```
+
+This function takes an entity and returns the chunk that contains it and the entity’s position (index) within that chunk. If the entity is not alive or is empty, the function returns `nil` for the chunk and `0` for the place.
+
+This is low-level functionality that you will rarely need. However, it can be useful in specific cases. For example, when you need to modify an entity’s component directly to avoid unnecessary [Deferred Operations](#deferred-operations) or [Fragment Hooks](#fragment-hooks), instead of using a higher-level function like [`evolved.set`](#evolvedset).
+
+```lua
+local evolved = require 'evolved'
+
+local health, stamina = evolved.id(2)
+
+local player = evolved.id()
+
+evolved.set(player, health, 100)
+evolved.set(player, stamina, 50)
+
+local player_chunk, player_place = evolved.locate(player)
+
+local health_components = player_chunk:components(health)
+local stamina_components = player_chunk:components(stamina)
+
+health_components[player_place] = 75
+stamina_components[player_place] = 42
+```
+
+> [!WARNING]
+> Do not use [`evolved.locate`](#evolvedlocate) to manipulate components directly unless you fully understand what you are doing. Because it is low-level functionality, incorrect use can lead to inconsistencies, as it bypasses the library’s safety checks and hook mechanisms. Use it only when you are certain it is safe and necessary.
+
 ### Structural Changes

 Every time we insert or remove a fragment from an entity, the entity will be migrated to a new chunk. This is done automatically by the library, of course. However, you should be aware of this because it can affect performance, especially if you have many fragments on the entity. This is called a `structural change`.

Their [`evolved.ON_ASSIGN`](#evolvedon_assign) hooks are never invoked for such tags for the same reason.
+
 #### Unique Fragments

 Some fragments should not be cloned when cloning entities. For example, `evolved.lua` has a special fragment called `evolved.PREFAB`, which marks entities used as sources for cloning. This fragment should not be present on the cloned entities. To prevent a fragment from being cloned, mark it as unique using the [`evolved.UNIQUE`](#evolvedunique) fragment trait. This ensures the fragment will not be copied when cloning entities.

+#### Internal Fragments
+
+All predefined fragments provided by the library are marked as internal with the [`evolved.INTERNAL`](#evolvedinternal) trait. Because [`evolved.INTERNAL`](#evolvedinternal) is itself marked as [`evolved.EXPLICIT`](#evolvedexplicit), these fragments are hidden from queries by default. This prevents accidental use of internal fragments in user code and helps distinguish them from user-defined fragments.
+
 #### Shared Components

 Often, we want to store components as tables, and by default, these tables will be shared between entities. This means that if you modify the table in one entity, it will be modified in all entities that share this table. Sometimes this is what we want. For example, when we want to share a configuration or some resource between entities. But in other cases, we want each entity to have its own copy of the table. For example, if we want to store the position of an entity as a table, we don't want to share this table with other entities. Yes, we can copy the table manually, but the library provides a little bit of syntactic sugar for this.

-## Backlog
-
- Improve the performance of required fragments by caching first-level required chunks.
- Improve the performance of builders that are used multiple times by caching hint chunks.
- Queries can cache major chunks to avoid finding them every time.
- Add a function to shrink storages to free unused memory.
- observers and events
- add INDEX fragment trait
- use compact prefix-tree for chunks
- optional ffi component storages
-
-## Thoughts
-
- We can return deferred status from modifying operations and spawn/clone methods.
- Should we make one builder:build method instead of :spawn and :clone?
- Should we cache the result of without_unique_fragments to clone faster?

+- We should have a way to not copy components on deferred spawn/clone.
+
+## Known Issues
+
+- Required fragments are slower than they should be
+- Errors in hooks are cannot be handled properly right now
