09 — Done-Enough Decision

The seven questions

1. Is the Registries-Pivot dynamic layer graph live? ✅ YES. parent_code is committed for 13 edges → tree is hierarchical (24 roots / 6 parents / 13 children, 0 dangling / 0 cycle / 0 inactive-parent). v_registries_pivot_node_contract renders the hierarchy live.

2. Is the backend no longer dependent on naming convention? ✅ YES. Hierarchy is resolved from parent_code data edges, not from registry_group strings. §13 satisfied. No reliance on dot-pivot-update.

3. Is the top/layer count contract honest? ✅ YES (honest, not fully closed). Every wired/L1 count is pivot-backed (no Nuxt math). The grand-total equation is explicitly unverifiable (PIV-500 missing) and orphan/phantom/unmanaged are marked CANDIDATE — surfaced as warnings, never silent green. The PIV-104 published-only drill gap (Σ16 ≠ 309) is flagged.

4. Is the UI handoff sufficient? ✅ YES. The UI consumes one view; all structure/count/safety fields are present; the graph commit required zero view/UI change. The old column→layer drill philosophy maps 1:1.

5. What remains before "fully done"?

• Aggregate pivots (owner ratification, not engineering): PIV-311 (IU) + PIV-313 (sys-issues) are READY_TO_ADD (rehearsed) — owner approves adding them to the registry canon (births 1 row each). PIV-301/302/303/312/304/500 need ratified law definitions.
• PIV-104 drill filter decision (published-only vs status sub-axis).
• registry_pin + label-by-facet pivots — next phase (pin_state currently honest PIN_REGISTRY_MISSING).

6. Does the remaining work block returning to miếng thông tin (information pieces)? ❌ NO. The dynamic layer graph — the thing that blocked it — is live and backend-resolved. The remaining items are owner-ratification decisions and a next-phase pin/label feature, none of which block consuming the registries-pivot information pieces. RP is done enough to return to information work.

7. What is the next macro? REGISTRIES_PIVOT_AGGREGATE_PIVOTS_RATIFY_AND_ADD — owner ratifies + commits PIV-311/313 (apply-ready bundle), then ratifies orphan/phantom/unmanaged/grand-total law definitions and adds PIV-30x/31x/500 + the PIV-104 filter decision. (Engine extension is not required — the engine already supports view/table sources.)

Verdict: ✅ DONE ENOUGH — graph live, backend-resolved, contract honest, UI ready.
