79 — SB-2 Rollback / Entry==Exit Verification (R5)

Doc: 79. Role: The numeric rollback proof for the SB-2 owner-line rehearsal — a {object, pre, post, equal?} certification that R2–R4 left zero footprint. Verified across two independent channels: the operator psql sessions (same-session post-ROLLBACK checks recorded in docs 76–78) and an independent query_pg read-only session (separate connection). Status: PASS — ENTRY == EXIT for every object. ZERO residue, ZERO emit, ZERO approval, NO law change, idle_in_transaction=0, NO COMMIT. Date: 2026-06-01.

79.1 SB-2 target objects absent (greenfield restored)

to_regclass	Pre (doc 75)	Post (R5, query_pg)	Equal?
governance_object_ownership	NULL	NULL	✅
governance_responsibility_scope	NULL	NULL	✅
v_object_effective_owner	NULL	NULL	✅
v_object_owner_gap	NULL	NULL	✅

Same-session post-ROLLBACK checks in docs 76/77/78 independently returned present=false for every created table/view.

Organic-growth tables (birth_registry, event_outbox, event_read, system_issues, registry_changelog) drift with live traffic and are not rehearsal residue — no rehearsal wrote to them. SB-2 rehearsal tables were all freshly created trigger-less tables, so no birth-registry / description-guard / provenance / emit side effects fired (unlike an SB-1 apr_action_types insert). Every governance-scoped probe = 0.

79.3 Verdict

R5 = PASS. Every object's pre == post across two independent channels. Zero governance residue; zero emit; zero approval; zero DOT; no law change; no leaked transaction or session (idle_in_transaction=0, workflow_admin sessions=0); no COMMIT occurred anywhere. No "clean-up" mutation was ever needed or performed (each transaction's own ROLLBACK restored the entry state). The rehearsal cycle was non-destructive and fully reversible — certifying the SB-2 substrate (governance_object_ownership + governance_responsibility_scope + resolution/gap views) as rehearsed-GREEN, build NO-GO.
