CHECKPOINT — RP Dynamic Drill Grouping / UI Production / First-Official Closeout (2026-06-05)

• Final status: PARTIAL (all safe branches complete; only authority/operator blockers).
• Execution mode: EXECUTION.
• Live mutation: YES — additive/birth-free (7 views). NO data/canon/ownership/vote/event/REAL_RUN/IU/git-push mutation.
• Dual-path verification: query_pg (RO) == ssh→docker→psql. birth_registry 1,194,855 before == after (7 CREATE VIEW, one COMMIT). trigger_guard_alerts 129 == 129. No engineering drift.

Grouping status before/after

• before: 10 AX-PXT nodes NEEDS_GROUPING (count>1, no child drill).
• after: 10 → 0 — all GROUPED with real per-object children (250 child groups).
• sources: v_trigger_universe_census (7 TRIG nodes, 525 triggers), wf_process_candidate (6 candidates), wf_orphan_remediation_queue (11 docker), v_workflow_residual_evidence_hardening_v4 (23 residual / 7 states).

Substrate status before/after

• before: 2 empty AX-PROCESS candidates (member_count=0, unexplained).
• after: 2 → 0 unexplained — WPC-MONITOR-BOOTSTRAP = EXPECTED_EMPTY_COMPONENT_BUCKET, WPC-UNCLASSIFIED = EXPECTED_EMPTY_EVIDENCE_GATED_CATCHALL. Both NOT_A_JOIN_BUG.

Proof matrix v2 status

v_rp_dynamic_drill_proof_matrix_v2 LIVE — 26 cases: 22 PASS / 4 PASS_WITH_EXPECTED_BLOCKER / 0 FAIL (12 original + 10 grouped + 2 empty + 2 authority-blocked).

Acceptance dashboard v2

v_rp_dynamic_drill_ui_acceptance_dashboard_v2 LIVE — missing_grouping 10→0, missing_substrate_unexplained 2→0, empty_classified 2, official_blocked 39, candidate 33, final_verdict = UI_DYNAMIC_DRILL_PROVEN_WITH_EXPECTED_BLOCKERS.

UI package v2 status

4 pass-through routes (grouping, contract-v2, proof-matrix-v2, acceptance-v2) + drill-v2 patch + INSTALL_AND_PR.md. Build/package-ready. NOT agent-deployed (divergent git ahead17/behind13 + no push creds). …/rp-dynamic-drill-grouping-2026-06-05/ui-package-v2/.

Smoke payload status

7 live paths captured (AX-BASE DOT, AX-TOPIC, job:cut, AX-PXT grouping db_dml 408→177 groups, new_candidates 6 groups, empty banner, final substrate). All PASS.

Officialization status (no-fake, live)

official AX-PROCESS RP 0 · AX-TRIGGER canon 0 · ownership 0 · PROC-OWN votes 0 (5 APR pending) · REAL_RUN 0 · process.* events 0/7 · real_run_enabled false · job:cut sole verified READY_FOR_PRESIDENT (PROC-OWN-03). Nothing faked; UI proof independent of authority.

Final verdict

UI_DYNAMIC_DRILL_PROVEN_WITH_EXPECTED_BLOCKERS.

Exact blockers

president PROC-OWN-01..05 (first official job:cut) · AX-TRIGGER owner/canon · AX-PROCESS official RP · REAL_RUN/event flip · UI operator deploy (divergent git). No engineering blocker.

Known gotchas (this run)

• MCP write_file uid=10001 → chown 10001:10001 staging dirs before writing.
• Proof matrix v1 case_id is integer, warning_flags is jsonb → cast case_id::text + jsonb_build_array(...) in v2 UNION.
• Contract node axis for the 10 grouping nodes = AX-PXT (join on that), while the ledger's semantic axis = AX-TRIGGER/AX-PROCESS (carried as semantic_axis).
• PXT ledger PROC counts (11/8/6) are static literals; residual literal 8 is stale vs live 2 (flagged LEDGER_LITERAL_STALE) — grouping uses live source.
• Apply via cat file | docker exec -i postgres psql (not psql -f hostpath).
