18000x · 09 — Regression Matrix

All IU Core write gates inert post-macro (10/10)

iu_core.composer_enabled               = false
iu_core.delivery_enabled               = false
iu_core.delivery_live_routes           = (empty)
iu_core.operator_runtime_enabled       = false
iu_core.retention_enabled              = false
iu_core.structure_ops_enabled          = false
iu_core.three_axis_auto_refresh_enabled= false
iu_core.vector_sync_enabled            = false
piece_event_runtime.dry_run_only       = true
piece_event_runtime.emit_enabled       = false

iu_core.routes_master_enabled=true and iu_core.route_worker_enabled=true are always-on by design (they govern internal event-flow plumbing, not "writes"). No change.

Qdrant — unchanged within macro

Collection	Pre	Post	Delta
iu_core_iu_chunks	149	149	0
production_documents	9456	9456	0 (external owner only — constitution forbids touch)

Vector boundary preserved: 149 indexed sync points cover the 141 unique IUs that have content (DIEU empty-body IUs intentionally skipped per 9000x onboarding policy).

DIEU axes preserved

DIEU corpus untouched at 18000x (mig 032 is purely sidecar; no fn touches information_unit for DIEU rows). The 1 new IU minted is iu_core/template/18000x/wf-onboarding-v2/step-5-d10-30-day-checkin — a template piece, not a DIEU.

production_documents untouched

Qdrant production_documents count was 9456 at baseline (external owner; 33 docs added between 15000x and 18000x); 9456 at post — within macro: 0 reads, 0 writes, 0 reindexes.

Healthcheck

fn_iu_collection_healthcheck returns 8 surfaces, all expected ok=true. No new healthcheck surface added in 18000x — the cross-template observability surface is a queryable VIEW, not a healthcheck row (per the 15000x decision to keep healthcheck at 8).
