12 — MCP-Readable Checkpoint (in-package copy)

This mirrors the standalone checkpoint at knowledge/dev/reports/architecture/checkpoint-topic-axis-pilot-apply-readiness-2026-06-04.md.

• final_status: PARTIAL (pilot substrate LIVE; ratification owner/GOV-COUNCIL gated)
• execution_mode: EXECUTION_MODE (additive only)
• live_mutation: YES (additive, reversible, rehearsed net-zero first; 0 births, 0 business-table change)
• axis_registry: LIVE — 1 row, AX-TOPIC = CANDIDATE
• axis_assignment: LIVE — 25 candidate rows, 7 distinct candidate nodes, evidence preserved
• ax_topic_status: CANDIDATE (active flip is owner-gated)
• topic_candidates: LIVE — 7 nodes from iu_metadata_tag topic:* (knowledge_graph10, architecture5, dot_trigger3, governance3, workflow2, cut_pipeline1, render_pipeline1)
• topic_pivots: LIVE as v_axis_topic_pivots (14 rows, PIV-310 FINAL_COMPUTABLE=5723; others CANDIDATE/NEEDS/DEFER); canon birth = operator packet
• axis_surface: LIVE — v_registries_pivot_axis_surface (DAG-aware, 7 rows) + fn_topic_node_substrate
• ui_api_packet: PATCH-READY (4 /axes routes + components; redeploy operator-gated; backend live)
• automation_bridge: READY_PARTIAL (data convention over axis_assignment/universal_edges/event_type_registry/approval_requests; routing rows deferred)
• safety_no_hardcode: PASS (no topic_level_1/2/3; no tree-only; no auto-active; STOP conditions encoded as warning_flags)
• next_macro: RP_UI_CONSUME_AXIS_SURFACE (primary); OWNER_APPROVAL_AXIS_APPLY in parallel (human gate); then TOPIC_AXIS_EDGE_POPULATION_AND_AUTOMATION
• exact_blocker: owner law-ratification of axis_registry/axis_assignment/AX-TOPIC + GOV-COUNCIL FAC-08 root approval (Điều 32); taxonomy node creation also gated by birth side-effects. No engineering blocker.
• report_path: knowledge/dev/reports/architecture/topic-axis-ratify-apply-pilot-populate-surface-automation-bridge-2026-06-04/ (docs 00–12)
• prod_access: query_pg RO + ssh contabo → docker postgres psql (role directus, owns tables) RW
• operator_files: axis_body / axis_commit / axis_rollback / axis_operator_packet (local /tmp)
