Backup

pg_dump -Fc → /opt/incomex/backups/directus-pre-iucore-240x-20260522T072323Z.dump — 75 919 722 bytes — sha256 1c77d96e831b8b252a0fe892610031baf418325b688a2ddc5a9874edfa4092dd — pg_restore -l lists 282 TABLE DATA entries, valid PGDMP header.

14 mandatory gates — all PASS

1. Host correct. 2. Target identity — container postgres, DB directus, host vmi3080463. 3. Backup taken + sha-verified. 4. DOT/no-hardcode/five-layer baseline clean — DOT 68/68. 5. Candidate scope discovered live. 6. Operation bounded + reversible. 7. Rollback authored before apply. 8. Vocabulary registry/CHECK-backed. 9. No duplicate source of truth — a composition references pieces by FK, stores only order + role. 10. From-scratch pieces minted only via the fn_iu_create birth gate. 11. Existing IU tree/lineage untouched. 12. Worker/delivery unchanged, cannot external-deliver. 13. Text-as-code import fail-closed + non-destructive. 14. Disable path known — the composer gate iu_core.composer_enabled is closable.

120x AgentData reports verified present — 8 documents under v0.6-iu-core-120x-three-axis-metadata-delivery-autocut-textcode-open-goal/. No repair needed.
