# EM-STR-04 provider comparison

Claude and Grok agree on a profile-only result with WM-ACT-030 as the sole Initiative root. Business Case is an immutable contained release, Alternative is an Initiative-scoped option with release-local appraisal values, and Investment Decision is a binding profile over WM-KNW-010, WM-ACT-024, WM-REC-010 and WM-ECO-012. No new model or runtime identifier is required.

Both reviews keep Initiative identity separate from delivery identity. Only formalization mints a new WM-ACT-005 Project, WM-ACT-029 Program or operation identity with typed derivation and handover. Tickets, approvals, mandates and funding availability never create delivery identity. Rejected Initiatives retain identity and all appraisal history.

Business Case releases bind one fair-comparison pin set: do-nothing baseline, criteria, horizon, price base, metric revisions, method and uncertainty. Alternative option identity remains stable between releases, but appraisal values, forecasts, risks and costs belong to each immutable release. New forecasts issue a successor release and never rewrite the record used for an earlier decision.

Assumption, Hypothesis, Risk/Opportunity and Budget remain external masters referenced by immutable revision or snapshot. WM-REC-010 freezes the complete decision join for as-of reconstruction. WM-ECO-012 retains funding mastership. Expected benefit is contained appraisal content or a pinned WM-KNW-015 Opportunity reference; no Benefit root is invented.

Portfolio-first capital decisions without one Initiative are outside EM-STR-04 and remain WM-ACT-029-owned. The disposition remains a held declarative profile pending parent and relation correction, source and version pins, allocated outcome/metric referents and canonical fixtures.

## Frozen-audit reconciliation

The single frozen audit accepted the profile with eight limits. The final candidate makes WM-REC-010 the decision address and WM-ACT-024 the temporal anchor, allocates stable option keys at Initiative scope, prevents unmastered shared pin sets, freezes funding state kind, records rejection with the same join discipline, keeps realized benefit under delivery mastership, prevents supersession-chain decision resolution and forbids retro-mapping portfolio decisions to mandates. No second audit was run and no identifier was added.
