 - **Apps**: Each Django app owns its models, views, API serializers, filtersets, forms, and tests.
-- **REST API**: DRF serializers live in `<app>/api/serializers.py`; viewsets in `<app>/api/views.py`; URLs auto-registered in `<app>/api/urls.py`.
+- **Views**: Use `register_model_view()` to register model views by action (e.g. "add", "list", etc.). List views typically don't need to add `select_related()` or `prefetch_related()` on their querysets: Prefetching is handled dynamically by the table class so that only relevant fields are prefetched.

 - API serializers must include a `url` field (absolute URL of the object).
 - Use `FeatureQuery` for generic relations (config contexts, custom fields, tags, etc.).
 - Avoid adding new dependencies without strong justification.
+- Avoid running `ruff format` on existing files, as this tends to introduce unnecessary style changes.
+- Don't craft Django database migrations manually: Prompt the user to run `manage.py makemigrations` instead.

+
+When pruning expired changelog entries (per `CHANGELOG_RETENTION`), retain each non-deleted object's original `create`
+change record and its most recent `update` change record. If an object has a `delete` change record, its changelog
+entries are pruned normally according to `CHANGELOG_RETENTION`.

+    remain subject to pruning per `CHANGELOG_RETENTION`.
+
+!!! warning
+    This setting is enabled by default. Upgrading deployments that rely on complete pruning of expired changelog entries

 ## Clusters

+Each cluster must have a type and operational status, and may be assigned to a group. (Both types and groups are user-defined.) Each cluster may designate one or more devices as hosts, however this is optional.
+
+## Virtual Machine Types
+
+A virtual machine type provides reusable classification for virtual machines and can define create-time defaults for platform, vCPUs, and memory. This is useful when multiple virtual machines share a common sizing or profile while still allowing per-instance overrides after creation.
 
 ## Virtual Machines
 
-A virtual machine is a virtualized compute instance. These behave in NetBox very similarly to device objects, but without any physical attributes. For example, a VM may have interfaces assigned to it with IP addresses and VLANs, however its interfaces cannot be connected via cables (because they are virtual). Each VM may also define its compute, memory, and storage resources as well.

+For example, a VM may have interfaces assigned to it with IP addresses and VLANs, however its interfaces cannot be connected via cables (because they are virtual).

A VM can optionally be assigned a [virtual machine type](../models/virtualization/virtualmachinetype.md) to classify it and provide default values for selected attributes at creation time.
+
+A VM can be placed in one of three ways:
+
+- Assigned to a site alone for logical grouping.
+- Assigned to a cluster and optionally pinned to a specific host device within that cluster.
+- Assigned directly to a standalone device that does not belong to any cluster.

 !!! warning
     Disabling the page size limit introduces a potential for very resource-intensive requests, since one API request can effectively retrieve an entire table from the database.
 
+### Cursor-Based Pagination
+
+For large datasets, offset-based pagination can become inefficient because the database must scan all rows up to the offset. As an alternative, cursor-based pagination uses the `start` query parameter to filter results by primary key (PK), enabling efficient keyset pagination.
+
+To use cursor-based pagination, pass `start` (the minimum PK value) and `limit` (the page size):
+
+```
+http://netbox/api/dcim/devices/?start=0&limit=100
+```
+
+This returns objects with an `id` greater than or equal to zero, ordered by PK, limited to 100 results. Below is an example showing an arbitrary `start` value.
+
+```json
+{
+    "count": null,
+    "next": "http://netbox/api/dcim/devices/?start=356&limit=100",
+    "previous": null,
+    "results": [
+        {

+            ...
+        }
+    ]
+}
+```
+
+To iterate through all results, use the `id` of the last object in each response plus one as the `start` value for the next request. Continue until `next` is null.
+
+!!! info
+    Some important differences from offset-based pagination:
+
+    * `start` and `offset` are **mutually exclusive**; specifying both will result in a 400 error.
+    * Results are always ordered by primary key when using `start`. This is required to ensure deterministic behavior.
+    * `count` is always `null` in cursor mode, as counting all matching rows would partially negate its performance benefit.
+    * `previous` is always `null`: cursor-based pagination supports only forward navigation.
