09 — Clone Lifecycle Decision (Objective H)

Decision: KEEP as golden regression harness

directus_gov_test_20260602 is now the most complete finalized embodiment of the One-Roof governance pipeline: 3 fully-activated axes (gap 0); ratified KG topic; facet-aware reconcile decision register; 11-detector drift suite incl real timestamp projection-lag detector; idempotent scanner; fail-closed event boundary; 7 live UI/API read views. Dropping it would discard a validated end-to-end harness. KEEP.

State preserved

Disk 1202 MB (host / has 21 GB free). Finalization data tagged TEST_CLONE_finalization_2026-06-03 (6 decisions, 35 containment assignments, 35 ownership, kg ratification+projection). Snapshot taken: /tmp/clone_finalized_2026-06-03.dump (92 MB compressed, in postgres container).

Levers (exact commands)

• KEEP (chosen): no-op.
• Snapshot: docker exec postgres pg_dump -U workflow_admin -Fc directus_gov_test_20260602 -f /tmp/clone_finalized_2026-06-03.dump (DONE, 92 MB).
• Reset finalization only: apply sql/Z_rollback_finalization.sql (restores pre-finalization views from _clone_defs.txt, deletes tagged rows).
• Reset whole substrate: prior Z_axis_substrate_drop_clone.sql + topic-promotion Z_rollback_A.sql.
• Drop: docker exec postgres psql -U workflow_admin -d postgres -c 'DROP DATABASE directus_gov_test_20260602' (~1.2 GB reclaim).

Recommendation

KEEP running; one snapshot taken (restorable); do NOT run Z_rollback (exists for reversibility proof/selective reset). Disk budget: 1202 MB live + 92 MB snapshot << 21 GB free. No concern.
