Function decide_acquire 

pub fn decide_acquire(
    status: AcquireStatus,
    consecutive_invalid: u8,
) -> AcquireAction

Pure acquire-error policy.

consecutive_invalid is the number of Invalid acquires already retried (via Reconfigure) since the last successful acquire; only the Invalid arm consults it. Host-testable: no wgpu state is touched here, only the counter the renderer tracks and resets on a successful acquire.
