07 — Backend Gap Closure (Track F)

Safe additive gaps closed (all birth-free; forbidden actions NOT taken).

Closed

1. No unified UI contract → v_rp_universal_node_ui_contract (all 5 axes).
2. No cross-axis substrate dispatcher → fn_rp_node_substrate(axis,node). Previously only 3 disjoint fns (base TABLE / process jsonb keyed on workflows.process_code / topic jsonb); AX-PROCESS candidates, job:cut, AX-TRIGGER classes, and Process×Trigger gaps had NO substrate fn.
3. AX-PROCESS candidate substrate → built from wf_process_candidate(_member).
4. job:cut substrate → built from job_queue (8 cut.* step-kinds). (fn_process_node_substrate returned NULL for job:cut — it keys on workflows, which job:cut is not.)
5. AX-TRIGGER class substrate → built from v_trigger_universe_census.
6. Process×Trigger gap substrate → built from v_process_trigger_actionability_ledger.
7. Base PIV- substrate key mismatch* → patched (02_patch_base_substrate.sql).
8. No substrate contract / proof matrix / acceptance dashboard → 3 new views.

Left open (NOT safe to auto-close — honest gaps)

• 2 empty WPC candidates (member_count=0): no substrate until members assigned/owner decides.
• 10 Process×Trigger gaps (object_count>1) NEEDS_GROUPING: need a cross-axis grouping rule (trigger-class ↔ process-owner) — owner/design decision, not an engineering gap.
• Official AX-PROCESS RP 0/453, PROC-OWN votes 0, REAL_RUN 0, event activation 0/7 → BLOCKED_AUTHORITY (president/owner only).

No canon/birth/owner/event/REAL_RUN/IU mutation occurred.
