//! The re-probe predicate: which trees the §7.2 sweep must look at again.

use super::needs_liveness_reprobe;
use crate::app::tests::harness::agent;
use crate::git_tree::{AgentState, GitTree};

/// Only a live agent can die *silently*, so only a live agent's workspace is
/// worth a poll. Asserted in both directions and on the empty tree, because
/// "re-probe everything" and "re-probe nothing" are the two ways this goes
/// wrong and each is invisible to the other's test.
