10 — Final Summary

Status: ✅ PASS — dynamic layer graph LIVE; aggregate-pivot path clarified + apply-ready bundle delivered. Execution mode: EXECUTION_MODE. Live mutation: YES — 13 parent_code edges committed.

Headline

The Registries-Pivot dynamic layer graph is now live and backend-resolved. One UPDATE (13 parent_code edges) turned the flat 37-pivot set into a hierarchy — 24 roots / 6 parents / 13 children, 0 dangling / 0 cycle / 0 inactive-parent — and v_registries_pivot_node_contract reports the hierarchy with zero view/UI change. Backend layer logic now depends on parent_code data, not naming convention.

What was done

1. Committed the 13-edge parent graph (backup, pre/post hashes, rollback saved).
2. Proved the count-refresh side-effect is bounded + documented: exactly one stale cache value corrected (PIV-201 entities +3); 0 meta_catalog changes; 0 L1-total changes; 0 business-table touch.
3. Corrected the engine model from live evidence: pivot_query already supports view/any-relation source_object → PIV-30x/31x do not need an engine extension; they need law ratification + accept the birth side-effect.
4. Delivered an apply-ready (owner-gated) bundle: PIV-311 (IU=219) + PIV-313 (sys-issues open=207,940), rehearsed clean (engine computes, births land, contract renders, rollback clean).
5. Honest count contract: equation surfaced as unverifiable-at-grand-total; orphan(59)/phantom(289)/unmanaged(NULL) marked CANDIDATE; PIV-104 published-only drill gap (Σ16≠309) flagged.

What changed vs prior macro (live wins)

• Prior: "PIV-30x/31x need pivot-engine extension." Now: engine already handles view/table sources; blocker is ratification, not engineering.
• Prior: graph apply-ready, commit held. Now: graph committed; tree hierarchical live.

Remaining (owner-gated, non-blocking)

1. Ratify + commit PIV-311/313 (apply-ready bundle; births 1 row each).
2. Ratify orphan/phantom/unmanaged/grand-total law defs → add PIV-301/302/303/312/304/500.
3. Decide PIV-104 drill filter (published-only vs status sub-axis).
4. registry_pin + label-by-facet — next phase.

Compliance

No RP cleanup; no dot-pivot-update; no birth/governance/pre-birth alteration (aggregate births rehearsed + rolled back only); no fake pivots; no Nuxt count math; no hardcoded depth; no new global exceptions. Reports + checkpoint published to KB and read back.
