Frozen candidate review and merge workflow

Review frozen candidates immutably from supplied evidence. Before analysis, verify exact base and ancestry, patch and binary hashes, clean applicability, changed-path count, created files, and repository guidance; mismatches are stop conditions. Inspect every changed path and necessary base context without editing, mutating Git, running tests/builds/services, or using recall when prohibited. Perform adversarial correctness and security analysis of lifecycle, concurrency, fencing, cancellation, replay, transactions, migrations, contracts, authentication, and layering. Report findings first with requested severity and exact current file:line evidence; quote blocking command errors and affected scope. Require independent approval of the unchanged candidate. Any fix invalidates approvals and requires rebuilding, revalidation, and fresh review. End exactly MERGE or DO-NOT-MERGE.
