IU Core Constitution/DOT Hygiene — 01 Precheck + production survey

Macro: IU_CORE_CONSTITUTION_DOT_HYGIENE_REPAIR_SCALE_READINESS_OPEN_GOAL Date: 2026-05-21 · audit + safe-repair pass before scale.

Host

MacBook/dev host (Nguyens-MacBook-Air, Darwin arm64). Repo /Users/nmhuyen/iu-cutter-build/repo/iu-cutter, branch main, HEAD 41d4fd7 (clean tree). Baseline 613 passed. Host gate PASS.

Target identity — positively production directus

query_pg (read-only role, 5 s timeout) against DB directus: current_database()='directus', information_unit=158, unit_version=165, iu_tree_path=158, event_outbox=93,686. This is the production directus DB, not the pg-restore-test sandbox. Identity gate PASS.

Drift survey — matches prior macro close-out exactly

Item	Value	Matches SSOT
master gate iu_core.routes_master_enabled	true (set 13:32:34)	yes
worker gate iu_core.route_worker_enabled	true (set 14:32:47)	yes
outbound route iu.version_applied.workflow	enabled=true, dry_run=true	yes
inbound route iu_sql.iu_sql_link.insert	enabled=false, dry_run=true	yes
event_outbox total / event_domain='iu'	93,686 / 0	yes
iu_route_attempt / iu_route_dead_letter	0 / 0	yes
iu-core triggers trg_iu_out_version / trg_iu_sql_in_iu_sql_link	both attached, enabled O	yes
data rows	iu_tree_path=158, iu_route_worker_cursor=1, iu_outbound_route=1, iu_sql_event_route=1, rest 0	yes

Zero drift from the worker-live-dry-run macro close-out. Drift gate PASS.

Production IU Core object inventory — 33 objects

• 9 tables: iu_sql_link, iu_sql_event_route, iu_outbound_route, iu_route_attempt, iu_tree_path, iu_structure_operation, iu_relation, iu_route_worker_cursor, iu_route_dead_letter.
• 5 views: v_iu_tree, v_iu_sql_link_resolved, v_iu_route_attempt_summary, v_iu_event_backlog, v_iu_route_dead_letter_open.
• 12 functions: fn_iu_core_routes_enabled, fn_iu_emit_event, fn_iu_outbound_on_version, fn_iu_sql_link_validate, fn_iu_sql_link_inbound_capture, fn_iu_tree_assert_acyclic, fn_iu_tree_is_descendant, fn_iu_route_worker_enabled, fn_iu_route_deliver, fn_iu_route_worker_run, fn_iu_route_dead_letter_replay, fn_iu_route_worker_health.
• 2 triggers: trg_iu_out_version (on unit_version), trg_iu_sql_in_iu_sql_link (on iu_sql_link).
• 2 dot_config gate keys · 1 event type (iu.version_applied) · 2 routes.

The pre-IU-Core iu_* objects (iu_lifecycle_log, iu_lifecycle_vocab, iu_notification_event, iu_notification_read, and the fn_iu_create/fn_iu_enact/fn_iu_notif_* lifecycle family) are out of IU Core scope and excluded from the inventory.

Mandatory gates before any production mutation

This macro performed no production mutation — only read-only query_pg catalog surveys. The narrow production-mutation approval (inert DOT/registry metadata) was therefore not exercised: every repair landed in the repo and the KB. No backup was required because no durable production write occurred. Gates 1–7 evaluated; mutation path not taken.
