IU Core Runtime Activation E2E — 02 Backup + drift check

Fresh backup (Gate 3)

Taken before any runtime mutation:

• Path: /root/backups/iu-core-runtime/directus-pre-iucore-runtime-20260521T105137Z.dump
• Command: docker exec 22540b78de8f pg_dump -U directus -Fc directus
• Size: 74,455,340 bytes
• sha256: fdb8754dbcaeb9339d99e75c7eb0eb102a015f4300b270a1f9bb737c79e84954
• Integrity: pg_restore -l lists 2981 TOC entries (valid custom-format archive).

Prior backup directus-pre-iucore-20260521T103010Z.dump (from the DDL macro) remains in /root/backups/iu-core-prod-ddl/.

Drift check (Gate 4) — production IU-core state before activation

Metric	Value	Expected (prior macro)	Match
current_database	directus	directus	yes
information_unit rows	158	158	yes
unit_version rows	165	165	yes
iu-core tables	7	7	yes
iu-core views	2	2	yes
iu-core functions (fn_iu_* of the 7)	7	7	yes
iu-core triggers attached	0	0	yes
master gate iu_core.routes_master_enabled	<absent> ⇒ off	absent	yes
iu-core data rows (7 tables)	0	0	yes
event_type_registry rows with domain iu	0	0	yes

The 7 iu-core functions confirmed present: fn_iu_core_routes_enabled, fn_iu_emit_event, fn_iu_outbound_on_version, fn_iu_sql_link_inbound_capture, fn_iu_sql_link_validate, fn_iu_tree_assert_acyclic, fn_iu_tree_is_descendant.

Production state matched the prior macro's record exactly — zero drift.
