02 — RP Classification Inventory (Objective A)

Live read of pivot_definitions (37 rows; 35 active, 2 inactive).

registry_group — 11 distinct, CONFLATES TWO FACETS

governance-domain (15 rows, VI): cấu_trúc(3)→FAC-02 LBL-101 exact, công_cụ(4)→LBL-104 exact, giám_sát(2)→LBL-105 exact, quy_trình(5)→no exact FAC-02 (process≠rule), dữ_liệu(1)→LBL-102? provisional. rp-local-pivot-kind (22 rows, EN, pivot SHAPE not governance): default(7), cross-table(6), l2-drill(6), matrix_l1(1), matrix_l2(1), test(1, dirty/inactive). Category error #1: one column, two meanings (domain vs shape). Cleanup = split registry_group into domain_facet (governed) + pivot_kind (RP-local).

species — 18 distinct (+null)

Every non-null species is a REAL governed entity_species code — 0 orphans. catalog(10,atom), governance_infra(4,atom), null(4), collection(2,molecule), dot_tool(2,atom), species(2 ambiguous-meta: governed meta-species 'Loại' comp=meta, both rows pivot over entity_species), agent/approval_request/checkpoint_set/checkpoint_support/checkpoint_type/dependency/module/page/table_ui/task/wcr/workflow/workflow_step (1 each). species='species' = ambiguous, NOT bug. 4 nulls = 3 matrix pivots (species-spanning, defensible) + 1 inactive _uncategorized (PIV-020).

composition_level — 7 distinct

Canonical (in entity_species): atom(14), molecule(11), compound(6). NON-canonical: matrix(3, RP-local shape), material(1)/building(1)/product(1) = dirty drill-levels (PIV-204/205/206, all catalog). Governed canonical set = {atom,molecule,compound,meta}; RP never uses meta, adds matrix+material/building/product. Category error #2: RP overloads composition_level with pivot drill-depth. Same governed entity catalog (intrinsically atom) labeled molecule/compound/material/product/building across PIV-001/101/202/203/204/205/206 = L1/L2 presentation depths, not entity composition.

Should map to governance: 15 governance-domain registry_group → FAC-02; all 33 non-null species → entity_species; all 32 canonical composition_level → entity_species.composition_level.
