Registries-Pivot Dynamic Drill — UI/PG Structure Proof (2026-06-05)

Macro: REGISTRIES_PIVOT_DYNAMIC_DRILL_UI_PG_STRUCTURE_PROOF_AND_OPERATIONAL_CLOSEOUT Mode: EXECUTION · Live mutation: YES (additive/birth-free DB views+fn; NO data/canon/git-push mutation) Final verdict: UI_DYNAMIC_DRILL_PROVEN_WITH_CANDIDATE_BLOCKERS

What was proven

Registries-Pivot can render the real PG structure from Layer 1 → drill (while count>1) → final substrate across all 5 axes (AX-BASE, AX-TOPIC, AX-PROCESS, AX-TRIGGER, Process×Trigger), with a single universal contract and NO Nuxt-side business math.

Built (live, birth-free — births 1,194,828 before == after across 3 applies)

1. fn_rp_node_substrate(axis_code, node_code) → jsonb — universal final-substrate dispatcher (all axes).
2. v_rp_universal_node_ui_contract — one UI contract row per node (87 nodes), every axis.
3. v_rp_node_final_substrate_contract — substrate metadata per node (exercises the dispatcher).
4. v_rp_dynamic_drill_proof_matrix — 12 cases, verdict computed LIVE → 12/12 PASS.
5. v_rp_dynamic_drill_ui_acceptance_dashboard — single-row operational verdict.

UI/API (handoff-final, build-ready, operator-gated deploy)

7 pass-through API routes + generic drill.vue + 7 render-model components, staged at /opt/incomex/docs/mcp-writes/rp-dynamic-drill-2026-06-05/ui-package/.

Honest gaps (shown, not hidden)

• 2 empty AX-PROCESS candidates (WPC-MONITOR-BOOTSTRAP, WPC-UNCLASSIFIED, member_count=0) → no substrate.
• 10 Process×Trigger gaps with object_count>1 → NEEDS_GROUPING (cross-axis grouping rule pending).
• Authority still blocked: official AX-PROCESS RP 0/453, PROC-OWN 0 votes, REAL_RUN 0 — shown as CANDIDATE/BLOCKED_AUTHORITY, never faked.
