ADR-008 and ADR-009 were concurrently allocated by two authors on
2026-08-17. adr-008-multi-tenancy-model.md (Four Planes) has earlier
provenance and keeps 008; 009 is left free for that lane. Hub authority
becomes ADR-010, federated namespaces ADR-011. Cross-references in ADR-007
updated.
A live demonstration of ADR-007 decision 1's own subject: sequential
allocation with concurrent writers. ADR numbering is not covered by that
decision, which governs PREFIX-WP-NNNN only — gap to close.

Central hub on railiance is authoritative as a reading of the repositories;
local instances become rebuildable caches, never peer databases. Local work
requires no hub at all — repo files are self-describing.
Classifies hub data by origin: file-derived (central derives, never accepts
pushes, conflicts are git conflicts) vs hub-native (central owns, needs a
write path and an append-only offline buffer). Neither kind needs a hub-side
conflict model.
Measured divergence: 955 local / 649 primary / 320 local-only, of which 288
are backed by files that all exist on disk. Only 28 orphans need
disposition, and they are the ADR-001 violations.
Corrects ADR-007's 'development read replica' wording — the workstation
instance was the larger of the two by 306 workplans.
