pub fn cascade_conflicts_with_paging(
kv_peer_set: bool,
flag_raw: Option<&str>,
) -> Result<bool>Expand description
Startup guard (env-free core): the cascade T1 (ATLAS_KV_LOCAL_GB > 0)
flushes evictions DOWN via per-head write_from_host, which the
block-record paging backend refuses — that combination must fail fast at
construction (PCND), never bail mid-decode on the first T1 eviction.
Returns true iff the incompatible combination is selected.
