# EM-LND-08 provider comparison

Claude and Grok independently agree that Commercial Landscape is a read-only governed profile, Market Scope is a versioned parameter edition and the served result is an immutable projection. None has independent business identity or lifecycle, so `newRuntimeId` remains false. Party and commercial facts stay mastered by their source models.

Both reviews preserve one Party across customer, supplier and partner roles without merging roles or netting their amounts. Grouping uses an evidence-qualified ownership/control or accounting-consolidation boundary, never CRM hierarchy. Unknown parents remain reason-coded singletons; disputed parent links preserve claimant attribution and produce ranges.

Grok sharpens calculation identity. Each concentration run binds exactly one grouping-boundary revision and one fact key. Intercompany elimination is allowed only inside an explicitly declared accounting-consolidation boundary containing both parties; ownership or control alone is insufficient. Two business perimeters produce two immutable projections and a group result set-unions facts rather than merging perimeter artifacts.

Forecast, pipeline, quote, order, subscription and observed revenue or delivery remain separate series. Coverage states remain backed, partial, unbacked-open, unbacked-lapsed or unevaluable. Unsupported does not mean false and unevaluable is not zero.

The final projection digest binds Market Scope edition, source revisions, fact key, grouping boundary, elimination rule, time, scenario, access grants, disclosure shape and calculation-engine revision. Cross-controller facts are excluded by default. A missing grant yields omission or typed unevaluable state without revealing whether a fact exists. Cross-period comparison requires matching semantic pins or governed remapping.

The disposition remains a held profile with no new identifier. Canonical publication depends on parent-model readiness, supplier boundary review, crosswalks, calibrated methods and fixtures.

## Frozen-audit reconciliation

The single frozen audit accepted the profile with five limits. The final candidate keeps disputed hypotheses inside one boundary revision, separates evidentiary `unevaluable` from hidden authorization denial, makes Market Scope authoritative over digest pins, requires external revisioned segmentation and coverage policies, and forbids cross-perimeter union across incompatible elimination semantics. No second audit was run and no identifier was added.
