10 — Final Summary

Status: PARTIAL (all safe engineering branches complete & live; blocker = owner law-ratification + operator UI redeploy)

Registries-Pivot is now the canonical, honest, pinnable, grouping-aware PG reflection surface for information-piece work. Workstreams A–G all completed or packaged.

Live mutations (5, additive, reversible, rehearsed net-0 first)

1. registry_pin table (pinning; empty). 2. rp_grouping_policy (+default threshold 50). 3. v_registries_pivot_node_contract REPLACE — pin_state honest; 25 other cols byte-identical. 4. v_registries_pivot_surface NEW — pin ordering + grouping. 5. v_pivot_dot_by_category REPLACE — stale published filter dropped → 25 groups/309 (agrees with PIV-104). No birth (1,132,025 before==after), no composition fix, no dot-pivot-update, no governance change.

Workstream results

• A — Aggregate law: 6 concepts explicit — orphan/phantom/drift CANDIDATE; KG/unmanaged NEEDS_LAW_DEFINITION; grand-total EQUATION_VIEW. 0 faked, 0 promoted.
• B — Pin: LIVE + proven (pin demo flipped PIV-019 PINNED & top-sorted, rolled back). Empty; owner inserts.
• C — Auto-grouping: LIVE + deterministic (default 50). DOT 309 SATISFIED; birth/issues/IU/PIV-005 NEEDS_GROUPING; small NOT_REQUIRED.
• D — UI/API: VERIFIED honest on core (PG-only, no Nuxt math, legacy parity, drill fn, FAILED-not-fake-green); PATCH-READY (P1–P5 + ticket RP_UI_CONSUME_SURFACE_AND_CANDIDATES); no redeploy.
• E — End-to-end: 5 live examples.
• F — Done-enough: DONE_FOR_INFORMATION_WORK=YES; DONE_FOR_UI_IMPLEMENTATION=YES (backend); ops PARTIAL.
• G — Handoff: doc 08.

Residual backlog (non-blocking)

UI redeploy P1–P5 + PIV-311/313 in leaf table + is_active filter (hide PIV-020/MTX-TEST); owner law (unmanaged, grand-total, candidate→canon, KG-edge, phantom retire); pin population; separate tracks untouched (governance/pre-birth; dot-pivot-update cleanup 146/uncategorized 142).

Exact remaining blocker: owner law-ratification + operator UI redeploy. RP engineering for information work complete.
