pub const DEFAULT_NAMESPACE: &str = "global";Expand description
v0.7.x (issue #1174 PR5 — pm-v3.1 namespace-sentinel sweep) — the
default namespace for AI-NHI memory writes when the caller omits
the namespace parameter. Bare value: "global".
Distinguished from GLOBAL_NAMESPACE (underscored "_global"),
which is the system-reserved namespace for substrate-internal
rows (governance, quotas, audit). NEVER conflate these — they
are different namespaces with different semantics. The
underscore prefix is the reserved-namespace convention.
