+**When to use:** Implementing table-oriented persistence behind an Application-owned
+Protocol. Never issue SQLAlchemy queries or construct Oper objects directly from
+chain, module, endpoint, Agent, scheduler, or workflow code.
 
 **Convention:** Each SQLAlchemy model in `app/db/models/` has a corresponding `<Model>Oper` class in `app/db/oper/<model>.py` — the two packages mirror each other file for file, so the module name carries the entity and the package carries the role.

-**Usage:**
+**Host usage:**
+
+Host entrypoints depend on an Application service or Protocol. The concrete
+`app/db/adapters/` implementation creates one operation-scoped Session, adapts the
+Protocol with Oper objects, and gives commit/rollback ownership to the Application
+command. Oper methods only query, stage, or flush in that caller-owned Session.
 
 ```python
-from app.db.oper.subscribe import SubscribeOper
+from app.application.subscription.write import SubscribeWriter
 
-oper = SubscribeOper()
-subscribe = oper.get(sid=1)
-oper.add(Subscribe(name="Example", type="电影"))
+def create_subscription(writer: SubscribeWriter, identity: dict, payload: dict):
+    return writer.add(identity=identity, payload=payload)
 ```
 
+The explicit Session/Oper composition belongs in `app/db/adapters/`, not at the
+host call site:
+
+```python
+with SessionFactory() as session:
+    command = CreateSubscriptionCommand(
+        repository=SubscribeOper(session),
+        unit_of_work=SqlAlchemyUnitOfWork(session),
+    )
+    result = command.execute(identity=identity, payload=payload)
+```
+
+The no-Session `SubscribeOper()` facade is legacy plugin ABI only. It may remain
+available through the curated SDK/Compat boundary, but new host code and examples
+must not copy that form.
