What this macro deliberately did NOT regress against

• production_documents count — external Directus drift; macro made zero writes.
• PR #669 state — channel-unaddressable in this clone (no remote).
• Nuxt build / deploy state — out-of-scope.
• Mac cron last-run timestamp — not queried.

delta = +11,211 B

Delta corresponds to: 20 lineage + 20 auto-log + 20 collection + 105 piece-membership rows + index/WAL residual. The pg_dump size delta is independent confirmation that the scaleout landed exactly the expected row deltas.
