+## CRUD
+
+### Facet keys now always use the full relationship chain
+
+In `v2`, relationship facet fields used only the terminal column key (e.g. `"name"` for `Role.name`) and only prepended the relationship name when two facet fields shared the same column key. In `v3`, facet keys **always** include the full relationship chain joined by `__`, regardless of collisions.

+    (User.role, Role.name) -> name

+    (User.role, Role.permission, Permission.name) -> role__permission__name
+    ```
+
+---
+
+## Models
+
+The lifecycle event system has been rewritten. Callbacks are now registered with a module-level [`listens_for`](../reference/models.md#fastapi_toolsets.models.listens_for) decorator and dispatched by [`EventSession`](../reference/models.md#fastapi_toolsets.models.EventSession), replacing the mixin-based approach from `v2`.
+
+### `WatchedFieldsMixin` and `@watch` removed
+
+Importing `WatchedFieldsMixin` or `watch` will raise `ImportError`.
+
+Model method callbacks (`on_create`, `on_delete`, `on_update`) and the `@watch` decorator are replaced by:
+
+1. **`__watched_fields__`** — a plain class attribute to restrict which field changes trigger `UPDATE` events (replaces `@watch`).
+2. **`@listens_for`** — a module-level decorator to register callbacks for one or more [`ModelEvent`](../reference/models.md#fastapi_toolsets.models.ModelEvent) types (replaces `on_create` / `on_delete` / `on_update` methods).
+
+=== "Before (`v2`)"
+
+    ```python
+    from fastapi_toolsets.models import WatchedFieldsMixin, watch
+
+    @watch("status")
+    class Order(Base, UUIDMixin, WatchedFieldsMixin):
+        __tablename__ = "orders"
+
+        status: Mapped[str]
+
+        async def on_create(self):
+            await notify_new_order(self.id)

+                await notify_status_change(self.id, changes["status"])
+
+        async def on_delete(self):
+            await notify_order_cancelled(self.id)
+    ```
+
+=== "Now (`v3`)"
+
+    ```python
+    from fastapi_toolsets.models import ModelEvent, UUIDMixin, listens_for
+
+    class Order(Base, UUIDMixin):
+        __tablename__ = "orders"
+        __watched_fields__ = ("status",)
+
+        status: Mapped[str]
+

+        await notify_new_order(order.id)

+        await notify_order_cancelled(order.id)
+    ```
+
+### `EventSession` now required
+
+Without `EventSession`, lifecycle callbacks will silently stop firing.
+
+Callbacks are now dispatched inside `EventSession.commit()` rather than via background tasks. Pass it as the session class when creating your session factory:
+
+=== "Before (`v2`)"
+
+    ```python
+    from sqlalchemy.ext.asyncio import async_sessionmaker, create_async_engine
+
+    engine = create_async_engine("postgresql+asyncpg://...")
+    SessionLocal = async_sessionmaker(engine, expire_on_commit=False)
+    ```
+
+=== "Now (`v3`)"
+
+    ```python
+    from sqlalchemy.ext.asyncio import async_sessionmaker, create_async_engine
+    from fastapi_toolsets.models import EventSession
+
+    engine = create_async_engine("postgresql+asyncpg://...")
+    SessionLocal = async_sessionmaker(engine, expire_on_commit=False, class_=EventSession)
+    ```
+
+!!! note
+    If you use `create_db_session` from `fastapi_toolsets.pytest`, the session already uses `EventSession` — no changes needed in tests.

+The event system provides lifecycle callbacks that fire **after commit**. If the transaction rolls back, no callback fires.
 
-`WatchedFieldsMixin` provides lifecycle callbacks that fire **after commit** — meaning the row is durably persisted when your callback runs. If the transaction rolls back, no callback fires.
+### Setup
 
-Three callbacks are available, each corresponding to a [`ModelEvent`](../reference/models.md#fastapi_toolsets.models.ModelEvent) value:
-
-| Callback | Event | Trigger |
-|---|---|---|
-| `on_create()` | `ModelEvent.CREATE` | After `INSERT` |
-| `on_delete()` | `ModelEvent.DELETE` | After `DELETE` |
-| `on_update(changes)` | `ModelEvent.UPDATE` | After `UPDATE` on a watched field |
-
-Server-side defaults (e.g. `id`, `created_at`) are fully populated in all callbacks. All callbacks support both `async def` and plain `def`. Use `@watch` to restrict which fields trigger `on_update`:
-
-| Decorator | `on_update` behaviour |
-|---|---|
-| `@watch("status", "role")` | Only fires when `status` or `role` changes |
-| *(no decorator)* | Fires when **any** mapped field changes |
-
-`@watch` is inherited through the class hierarchy. If a subclass does not declare its own `@watch`, it uses the filter from the nearest decorated parent. Applying `@watch` on the subclass overrides the parent's filter:
+Event dispatch requires [`EventSession`](../reference/models.md#fastapi_toolsets.models.EventSession). Pass it as the session class when creating your session factory:
 
 ```python

+SessionLocal = async_sessionmaker(engine, expire_on_commit=False, class_=EventSession)

+
+!!! info "Callbacks fire on `session.commit()` only — not on savepoints."
+    Savepoints created by [`get_transaction`](db.md) or `begin_nested()` do **not**
+    trigger callbacks. All events accumulated across flushes are dispatched once
+    when the outermost `commit()` is called.
+
+### Events
+
+Three event types are available, each corresponding to a [`ModelEvent`](../reference/models.md#fastapi_toolsets.models.ModelEvent) value:
+
+| Event | Trigger |
+|---|---|
+| `ModelEvent.CREATE` | After `INSERT` commit |
+| `ModelEvent.DELETE` | After `DELETE` commit |
+| `ModelEvent.UPDATE` | After `UPDATE` commit on a watched field |
+
+!!! warning "Callbacks fire only for ORM-level changes. Rows updated via raw SQL (`UPDATE ... SET ...`) are not detected."
+
+### Watched fields
+
+Set `__watched_fields__` on the model to restrict which field changes trigger `UPDATE` events. It must be a `tuple[str, ...]` — any other type raises `TypeError`:
+
+| Class attribute | `UPDATE` behaviour |
+|---|---|
+| `__watched_fields__ = ("status", "role")` | Only fires when `status` or `role` changes |
+| *(not set)* | Fires when **any** mapped field changes |
+
+`__watched_fields__` is inherited through the class hierarchy via normal Python MRO. A subclass can override it:
+
+```python
+class Order(Base, UUIDMixin):
+    __watched_fields__ = ("status",)
     ...
 
 class UrgentOrder(Order):
-    # inherits @watch("status") — on_update fires only for status changes
+    # inherits __watched_fields__ = ("status",)

Every callback receives three arguments: the model instance, the [`ModelEvent`](../reference/models.md#fastapi_toolsets.models.ModelEvent) that triggered it, and a `changes` dict (`None` for `CREATE` and `DELETE`):
 
 ```python
-from fastapi_toolsets.models import ModelEvent, UUIDMixin, WatchedFieldsMixin, watch
+from fastapi_toolsets.models import ModelEvent, UUIDMixin, listens_for
 
-@watch("status")
-class Order(Base, UUIDMixin, WatchedFieldsMixin):
+class Order(Base, UUIDMixin):
     __tablename__ = "orders"
+    __watched_fields__ = ("status",)
 
     status: Mapped[str]
 
-    async def on_event(self, event: ModelEvent, changes: dict | None = None) -> None:
-        if event == ModelEvent.CREATE:
-            await notify_new_order(self.id)
-        elif event == ModelEvent.DELETE:
-            await notify_order_cancelled(self.id)
-        elif event == ModelEvent.UPDATE:
-            await notify_status_change(self.id, changes["status"])
+@listens_for(Order, [ModelEvent.CREATE])
+async def on_order_created(order: Order, event_type: ModelEvent, changes: None):
+    await notify_new_order(order.id)
+
+@listens_for(Order, [ModelEvent.DELETE])
+async def on_order_deleted(order: Order, event_type: ModelEvent, changes: None):
+    await notify_order_cancelled(order.id)
+
+@listens_for(Order, [ModelEvent.UPDATE])
+async def on_order_updated(order: Order, event_type: ModelEvent, changes: dict):
+    if "status" in changes:
+        await notify_status_change(order.id, changes["status"])
 ```
 
-#### Option 2 — targeted overrides
+Multiple handlers can be registered for the same model and event. Handlers registered on a parent class also fire for subclass instances.
 
-Override individual methods for more focused logic:
+A single handler can listen for multiple events at once. When `event_types` is omitted, the handler fires for all events:
 
 ```python
-@watch("status")
-class Order(Base, UUIDMixin, WatchedFieldsMixin):
-    __tablename__ = "orders"
+@listens_for(Order, [ModelEvent.CREATE, ModelEvent.UPDATE])
+async def on_order_changed(order: Order, event_type: ModelEvent, changes: dict | None):
+    await invalidate_cache(order.id)
 
-    status: Mapped[str]
-
-    async def on_create(self) -> None:
-        await notify_new_order(self.id)
-
-    async def on_delete(self) -> None:
-        await notify_order_cancelled(self.id)
-
-    async def on_update(self, changes: dict) -> None:
-        if "status" in changes:
-            old = changes["status"]["old"]
-            new = changes["status"]["new"]
-            await notify_status_change(self.id, old, new)
+@listens_for(Order)  # all events
+async def on_any_order_event(order: Order, event_type: ModelEvent, changes: dict | None):
+    await audit_log(order.id, event_type)
 ```
 
-#### Field changes format
+### Field changes format
 
-The `changes` dict maps each watched field that changed to `{"old": ..., "new": ...}`. Only fields that actually changed are included:
+The `changes` dict maps each watched field that changed to `{"old": ..., "new": ...}`. Only fields that actually changed are included. For `CREATE` and `DELETE` events, `changes` is `None`:
 
 ```python
+# CREATE / DELETE → changes is None
 # status changed   → {"status": {"old": "pending", "new": "shipped"}}
 # two fields changed → {"status": {...}, "assigned_to": {...}}
 ```
 
 !!! info "Multiple flushes in one transaction are merged: the earliest `old` and latest `new` are preserved, and `on_update` fires only once per commit."
 
-!!! warning "Callbacks fire only for ORM-level changes. Rows updated via raw SQL (`UPDATE ... SET ...`) are not detected."
-
-!!! warning "Callbacks fire after the **outermost** transaction commits."
-    If you create several related objects using `CrudFactory.create` and need
-    callbacks to see all of them (including associations), wrap the whole
-    operation in a single [`get_transaction`](db.md) block. Without it, each
-    `create` call commits independently and `on_create` fires before the
-    remaining objects exist.
-
-    ```python
-    from fastapi_toolsets.db import get_transaction
-
-    async with get_transaction(session):
-        order = await OrderCrud.create(session, order_data)
-        item  = await ItemCrud.create(session, item_data)
-        await session.refresh(order, attribute_names=["items"])
-        order.items.append(item)
-    # on_create fires here for both order and item,
-    # with the full association already committed.
-    ```
-
-## Composing mixins
-
-All mixins can be combined in any order. The only constraint is that exactly one primary key must be defined — either via `UUIDMixin` or directly on the model.
-
-```python
-from fastapi_toolsets.models import UUIDMixin, TimestampMixin
-
-class Event(Base, UUIDMixin, TimestampMixin):
-    __tablename__ = "events"
-    name: Mapped[str]
-
-class Counter(Base, UpdatedAtMixin):
-    __tablename__ = "counters"
-    id: Mapped[int] = mapped_column(primary_key=True, autoincrement=True)
-    value: Mapped[int]
-```
