pub const ALL: &[&str];Expand description
Closed family of tatara-owned finalizer keys in declaration
order: PROCESS, ALLOCATION, POOL. Downstream sweeps
(a per-owner coverage report, a fleet-wide finalizer audit
binary, an ops diagnostic dumping every tatara-owned finalizer
on a cluster) iterate through this ONE slice rather than
re-listing the three consts by hand.
Pinned to length 3 by [tests::all_matches_declared_family] so
a future addition to the family cannot slip past the coherence
harness without landing here first.
