-Traces how ``sync_database_permissions_task`` binds an acting identity.
-
-The Celery task receives the immutable ``id`` of the user who enqueued it
-(captured at enqueue time by ``SyncPermissionsCommand.validate``), not a
-mutable username string. At execution time it resolves that id to a user
-record via ``security_manager.get_user_by_id`` and binds the result to
-``flask.g.user`` for the duration of the sync. Because resolution is by id,
-a username change between enqueue and execution has no effect on which user
-record the task acts as.
-
-That identity is not just used for logging: ``Database._get_sqla_engine``
-reads ``g.user.id`` to look up a per-user OAuth2 access token, and, for
-databases with ``impersonate_user`` enabled, ``Database.get_effective_user``
-reads ``g.user.username`` (via ``get_username()``) to pick the identity the
-outgoing connection impersonates at the external database. These tests pin
-down both halves of that chain: the id-based resolution in the task, and the
-fact that the resolved user is what a privileged, identity-sensitive
-codepath consumes downstream.
