Checkpoint — RP Aggregate Pivots Ratify/Add + DOT Drill Fix (MCP-readable short proof)

Live mutation

YES — 3 in-scope mutations. pivot_definitions 37→39 (active 35→37, roots 24→26, children 13, parents 6). birth_registry 1,132,011→1,132,013. parent-graph hash 91576fb6… → 8c5d25a8….

Added pivots (FINAL, LIVE)

• PIV-311 Information Units — Total = 219 (source information_unit), pivot_backed L1 root, born.
• PIV-313 System Issues (open) — Total = 207,940 (source system_issues, status='open'), pivot_backed L1 root, born.
• Inserted in ONE statement (1 refresh, 2 births); rehearsed BEGIN..ROLLBACK net-0 first (entry hash == exit hash).

Candidate pivots status (surfaced in additive register v_rp_aggregate_candidate_register, NOT canon)

• PIV-301 orphan=59 → CANDIDATE_REPORT_ONLY (birth-grain; ≠ per-collection orphan_count).
• PIV-302 phantom=289 → CANDIDATE_REPORT_ONLY (birth-grain; ≠ dot_tools record_surplus 146; no retire mechanism).
• PIV-303 count_drift=3 rows → CANDIDATE_REPORT_ONLY (row-count drift flag; ≠ surplus-equation drift 21,197).
• PIV-312 KG edges=2,259 → NEEDS_LAW_DEFINITION (edge-as-registry-object undefined; not completeness).
• None added to canon (would birth unretirable rows + assert unratified law); all live-counted in the register.

PIV-104 / DOT drill decision

FIXED (option 1 = smallest clean). Dropped stray status='published' filter (metadata UPDATE, no birth). DOT-by-category now 25 groups summing to 309; v_rp_drill_reconciliation shows PIV-007 RECONCILES (309=309), also PIV-009=168 & PIV-016=42 RECONCILE; NO WARNING_DRILL_MISMATCH remains. Separate dot_tools record-surplus drift (counted 309 vs actual 163 = 146 phantom-candidate) retained/surfaced honestly — different signal.

PIV-500 / PIV-304 decision

• PIV-500 grand total = NOT_A_PIVOT_BUT_EQUATION_VIEW; UNVERIFIABLE until a ratified anchor set defines "a system object"; equation = counted + orphan + phantom + unmanaged; no number faked.
• PIV-304 unmanaged = NEEDS_LAW_DEFINITION; law draft provided (no birth AND no governed registry/dot_tools/file entry); surfaced as NULL, never 0.

Count integrity status

Honest/non-fake-green. unmanaged NULL + PIV-500 missing ⇒ count_integrity_status=unverifiable_at_grand_total (warning). Taxonomy live for UI: FINAL / DRILLDOWN / CANDIDATE / PIVOT_MISSING / LAW_DEFINITION_NEEDED / WARNING_DRILL_MISMATCH(none) / UNVERIFIABLE. UI reads node contract + 2 additive views; no Nuxt math, no hardcoded depth.

Done-for-information-work

YES. Also DONE_FOR_UI_IMPLEMENTATION (read-only). Graph live, key aggregates live, DOT drill honest, PIVOT_MISSING explicit, final substrate present, no dot-pivot-update dependency.

Exact remaining blocker

Owner ratification only (not engineering): unmanaged + grand-total law defs; candidate→FINAL promotion criteria. Engineering complete.

Rollback

/tmp/rp_agg_rollback.sql — restore PIV-104 filter; DELETE PIV-311/313 (optional birth cleanup line; else 2 phantom births); DROP the 2 views. Base node contract untouched.
