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

• Final status: PARTIAL (all safe branches complete; only authority/design/operator blockers).
• Execution mode: EXECUTION.
• Live mutation: YES — additive/birth-free (1 function + 4 views). NO data/canon/ownership/vote/event/REAL_RUN/IU/git-push mutation.
• Dual-path verification: query_pg (RO) == ssh→docker→psql. births 1,194,828 before == after (×3 applies). No engineering drift (node_contract 39, axis_surface 7, ledger 12, axis_registry 2, axis_assignment 25, wf_process_candidate 19 — all MATCH).
• UI contract status: LIVE — v_rp_universal_node_ui_contract (87 nodes; AX-BASE 39 / AX-PROCESS 22 / AX-PXT 12 / AX-TOPIC 7 / AX-TRIGGER 7). 19 contract columns; drill_action computed in PG.
• Substrate contract status: LIVE — fn_rp_node_substrate(axis,node) + v_rp_node_final_substrate_contract. 85/87 nodes resolve to real PG tables. Base PIV-* key mismatch found & patched (02_patch).
• Proof matrix status: LIVE — v_rp_dynamic_drill_proof_matrix 12/12 PASS (verdicts computed live).
• Axes proven: AX-BASE, AX-TOPIC, AX-PROCESS, AX-TRIGGER, Process×Trigger (AX-PXT).
• Backend gaps: 2 empty AX-PROCESS candidates (member_count=0 → no substrate); 10 Process×Trigger gaps object_count>1 → NEEDS_GROUPING (cross-axis grouping rule pending = design, not bug). Honest, shown.
• UI branch/build status: handoff-final, build-ready. 7 pass-through API routes + generic drill.vue + 7 render-model components at /opt/incomex/docs/mcp-writes/rp-dynamic-drill-2026-06-05/ui-package/. NO agent push (main cron-owned; feat/process-axis-dashboard divergent). Operator install/PR/rollback in INSTALL_AND_PR.md.
• Acceptance dashboard: LIVE — v_rp_dynamic_drill_ui_acceptance_dashboard: ui_contract_ready true, substrate_contract_ready true, 12/12, axes 5, missing_grouping 10, missing_substrate 2, official_blocked 39, candidate 33.
• Final verdict: UI_DYNAMIC_DRILL_PROVEN_WITH_CANDIDATE_BLOCKERS.
• Can user start at Layer 1 / drill while count>1 / reach final substrate? YES / YES / YES.
• Nuxt hardcode? None (PG renders all business logic).
• No-fake (unchanged): official AX-PROCESS RP 0/453, PROC-OWN 0 votes, ownership 0, REAL_RUN 0, real_run_enabled false, events 0/7, AX-TRIGGER not in axis_registry, job:cut sole verified (8, READY_FOR_PRESIDENT).
• Exact blockers: (1) president PROC-OWN vote → first official AX-PROCESS; (2) owner birth/ownership (WPC candidates, AX-TRIGGER classes); (3) cross-axis grouping rule for 10 PXT gaps; (4) operator UI push/deploy; (5) REAL_RUN flip / event activation. NO engineering blocker.
• Next macro: AX_PROCESS_TRIGGER_GROUPING_RULE_AND_UI_DEPLOY_AND_FIRST_OFFICIAL_PROCESS.
• Artifacts: report dir registries-pivot-dynamic-drill-ui-pg-structure-proof-2026-06-05/00..14; SQL …/rp-dynamic-drill-2026-06-05/{01_apply,02_patch_base_substrate,99_rollback}.sql; UI …/ui-package/.
• GOTCHAS: fn_process_node_substrate keys workflows.process_code (NOT job:cut/WPC); base substrate fn keys registry leaf code (NOT PIV-*) → use node_contract; wf_process_candidate col=candidate_code; v_ax_process_candidate_layer_nodes col=node_id; query_pg 5s timeout → filter substrate contract by node; CREATE VIEW/FUNCTION birth-free.
