multi-tenancy.md: new DevVM Workstation section (roster SSoT, tiers, config inheritance, locked clone, built-vs-gated status). service-catalog.md t3code row: corrected the stale 'source of truth = /etc/ttyd-user-map' (now roster.yaml; the map/dispatch are GENERATED). offboard-user.md: written (was a referenced-but-missing dead link) — staged reversible-cut-then-gated-destructive for both cluster + workstation surfaces.
