pub const KV_DOMAIN: u64 = 0x4B56_5041_4745_0001;Expand description
Domain separator folded into every KV namespace so a KV wire key is
domain-separated from SSM keys IN THE KEY MATERIAL, not merely by the
peer’s (kind, blob_bytes) registry keying (which already gives each kind
its own residency map + swap file — this fold makes cross-kind aliasing
unrepresentable even if that registry keying were ever collapsed).
Frozen; mnemonic "KV" + "PAGE" + 1. The SSM decode tier’s analog is
atlas_kernels::DECODE_DOMAIN.
