`assert False` inside a `try:` raises AssertionError, which the `except Exception` right below it catches, so several tests reported green no matter what the code did. `pytest.fail` raises Failed, a BaseException, and escapes. A bare `a == b` statement is evaluated and discarded. Nine of those sat in tests, and one was comparing against a model name the router never produces. Selects B011, B015, B018, PT015, PLR0133 and PLW0127 in ruff-tests.toml alongside F821, with all 50 existing violations fixed, so no budget file or ratchet is needed. CI already runs this config over tests/.

"""Client for budget e2e tests: the shared ProxyClient plus budget-bearing entity

management (user / team / team-member / org / customer / tag / budget-table) and

Over-budget surfaces as a ``budget_exceeded`` error; ``is_budget_block`` detects it
|
|
on a chat outcome. Create methods return the new id and raise on failure; tests
|

register the matching delete with ``resources.defer(...)`` for cleanup. The request
