02 — Objective A: Governed Topic / Axis Promotion — PASS

Artifact: sql/A_topic_promotion.sql (single BEGIN..COMMIT, self-guarded). Rollback: sql/Z_rollback_A.sql. Tag: TEST_CLONE_topic_promo_2026-06-03.

Committed on the clone

• A1 Containment axis candidate→active (lifecycle register→active). Reference axis (structural/deterministic), no coverage_rule — does not impose ownership cells. 3 axes now active.
• A2 New topic values, 3 provenance lanes: observability (ai_proposed)→active; data-platform (human_designated)→active; kg-domain-x (kg_provisional) held candidate (provisional, not auto-activated). Lifecycle = INSERT candidate then UPDATE active, proven in-txn.
• A3 Split: active child workflow-exec (parent=workflow, op=split).
• A4 Deprecate/merge: gov-legacy → deprecated, provenance merged_into=governance.
• A5 Ownership ratification: accountable owner for modules/workflow (GOV-DOT, kind=human_ratified) — human override of the low-confidence (0.55) assignment.

Result — topic gap reached expected target

Coverage gap 2 → 1 (self-guard asserted exactly −1). Topic axis: required 6, gap 1, ok 3, low_conf 1, stale 1, quarantine 1. Remaining gap = iu_staging_record/ai-ops (quarantine) — correctly uncovered; quarantine items must be cleared before ownership (fail-closed, not a defect).

Value lifecycle post-commit: active 7, candidate 1 (kg-domain-x), deprecated 1 (gov-legacy).

Verdict

PASS. Candidate→active lifecycle, all 3 provenance lanes, split, merge, deprecate, ownership ratification all proven & committed on clone; production untouched.
