11 — Final Summary

Outcome

Moved the Topic Axis from locked design to a live additive pilot + a complete owner/operator apply packet for the gated remainder. PARTIAL by design (owner/GOV-COUNCIL approval is the only remaining gate); all safe branches completed.

Live mutations (additive, reversible, rehearsed net-zero first)

Object	Kind	State
axis_registry	table	LIVE; 1 row AX-TOPIC = CANDIDATE
axis_assignment	table (+3 indexes)	LIVE; 25 candidate rows, 7 nodes
v_registries_pivot_axis_surface	view	LIVE; 7 DAG-aware candidate rows
v_axis_topic_pivots	view	LIVE; 14 pivots PIV-310/320..332
fn_topic_node_substrate	function	LIVE; DAG-aware resolver

Births created: 0. Business tables changed: 0. Source iu_metadata_tag tags: 25 → 25 (untouched). Rollback script ready.

What each workstream delivered

• A axis substrate — LIVE (2 generic tables, no island, no hardcode).
• B AX-TOPIC — LIVE as CANDIDATE, backed by FAC-08 (taxonomy_facets id 9).
• C reconciliation — LIVE; 7 topic keys / 25 tags → candidate assignments with evidence_ref.
• D pivots — LIVE computable view (honest classifications); canon birth in packet.
• E surface + resolver — LIVE, DAG-aware.
• F UI/API — patch-ready packet (4 routes + components; no redeploy).
• G automation bridge — partial: data convention over axis_assignment/edges; routing rows deferred.
• H safety audit — all no-hardcode / STOP / forbidden checks PASS.
• I decision — next macro RP_UI_CONSUME_AXIS_SURFACE; checkpoint written.

Honest numbers (live 2026-06-04)

IU 219; documents 5,723; iu_relation 60; universal_edges 2,199; taxonomy active 57 (FAC-08 = 0 nodes); topic candidates 7; topic assignments 25; approved roots 0; orphan topics 7; governance gap 7.

Blocker

Owner law-ratification + GOV-COUNCIL FAC-08 root approval (Điều 32). No engineering blocker.
