Resolves a contradiction in accepted canon: ADR-007 decision 1's globally
unique forward-only running numbers require a central allocator, the exact
dependency federation must survive. Amended to namespace-scoped uniqueness
with PREFIX-WP-NNNN@namespace qualification; unqualified still means the
local namespace. C2's UUIDv5 derivation input becomes (namespace,
identifier) — free now, expensive after it ships.
States reconciliation limits rather than implying convergence. T0 fork, T1
sync and T2 reintegration are partly automatable; T3 amalgamation, where a
fork established distinct operational infrastructure, is an M&A-class
governed programme rather than a merge, and may legitimately end in
permanent coexistence or divestment. prj-state-hub-retirement is cited as
measured T3 cost under the most favourable possible conditions.
Coexistence, not merging, is the normal case: client instances per
CUST-WP-0058 are forks that never return. Records fork; effects do not.
