02 — Universal UI Contract (Track A)

Object: v_rp_universal_node_ui_contract (read-only view, birth-free). One contract row per node, every axis. The UI renders this verbatim — no axis-specific business logic in Nuxt.

Columns (the contract)

axis_code, node_code, label, count_value, count_status, lifecycle_status, governance_status, warning_flags(jsonb), has_children, child_count, child_node_codes(text[]), grouping_status, final_substrate_ref, substrate_available, drill_action, next_route, owner_blocker, related_axes(jsonb), proof_source

Core drill rule (computed in PG, not Nuxt)

• count_value > 1 AND has_children → drill_action = DRILL
• count_value > 1 AND NOT has_children AND NOT substrate → NEEDS_GROUPING
• otherwise → SHOW_SUBSTRATE

Live coverage (87 nodes)

axis	nodes	drillable	with_substrate	needs_grouping	source
AX-BASE	39	5	39	0	v_registries_pivot_node_contract
AX-PROCESS	22	18	20	0	wf_process_candidate + job:cut + workflows
AX-PXT	12	0	12	10	v_process_trigger_actionability_ledger
AX-TOPIC	7	0	7	0	v_registries_pivot_axis_surface
AX-TRIGGER	7	7	7	0	v_ax_trigger_surface

Unifies: base pivot nodes, AX-TOPIC candidate nodes, AX-PROCESS candidates (WPC-*) + sole-verified job:cut + 2 official workflows, AX-TRIGGER census classes, and Process×Trigger ledger gaps. Every row carries honest governance/lifecycle status (candidate / blocked / verified) and owner_blocker.

No-hardcode guarantee

All counts, drill rules, child sets, and statuses come from PG views/functions. Nuxt does zero math.
