06 — Final Regression Suite (Objective E)

sql/E_regression.sql — read-only, 10 dimensions, terminal assertion.

1. Ownership coverage: v_object_owner_gap = 0.
2. Axis coverage: containment active req=35 gap=0 ok=35; responsibility req=210 gap=0; topic req=6 gap=1 (iu_staging_record quarantine, correct).
3. Axis registry: containment 5 values/35 assign/1 rule; responsibility 6/0/1; topic 8/6/1.
4. Reconcile: label_orphans=0, orphan_entities=0, topics_without_label=2, labels_without_topic=48, divergent=0, projection_gaps=0.
5. Drift (38 open, 0 critical): axis_assignment_missing info 29; projection_lag_timing info 1 + warning 3; stale_candidate info 1; topic_without_label info 2; low_confidence_assignment warning 1; ui_visible_unapproved warning 1. All legit operational signals.
6. Scanner idempotency: runs (7:38,0,0)(6:38,0,0)(5:38,4,7) — stable, bounded, no daemon.
7. Event/issue boundary fail-closed: v_drift_issue_payload 38 rows, 38 blocked, 0 emittable; gov event_outbox=0; gov event types active=false.
8. UI/API reads (all live): coverage_dashboard {ownership_gap:0, topic_gap:1, active_axes:3, open_drift:38, critical_drift:0, review_queue_size:6, reconcile{divergent:0,projection_gaps:0}}; axis_browser=3, topic_tree=9, object_topic=6, review_queue=6, detector_findings=38, lane=5 official/1 candidate.
9. Persistence: kg-domain-x=active/kg_ratified; containment assignments=35; ownership=35.
10. Terminal assert: REGRESSION PASS own_gap=0 crit=0 divergent=0 proj_gap=0 emittable=0 containment_gap=0 kg=active.

Verdict: full regression green. Zero critical drift, fail-closed events, all projections live, all commits persisted.
