• relationship("AlertFlowGraph", cascade="all, delete") is called without assigning it to a mapped attribute, so it has no effect (the relationship/cascade won’t be configured on the model). Either assign it to a class attribute (with an appropriate Mapped[...] type) or remove this line to avoid giving a false impression that ORM-level cascading is enabled.

    created: Mapped[str | None]
    valid: Mapped[bool] = mapped_column(nullable=False, default=True)
    completed: Mapped[bool] = mapped_column(nullable=False, default=False)

    relationship("AlertFlowGraph", cascade="all, delete")
