Projects move to the conventional src/ and tests/ layout: the four shipping-side projects (SqlServerSimulator, .EFCore, .Analyzers, Example) under src/ and the six test projects under tests/ with the solution, Directory.Build.props, and Directory.Packages.props staying at the root. The only content changes are path fixups.

 A full build + test cycle runs 20–30s; single-test filter (`--filter "FullyQualifiedName~Foo"`) stays fast. Still cheap enough to treat `dotnet test` as a verifier between micro-edits, not a checkpoint.

 Per-element exceptions land on `Skipped` with a `"Load failed: …"` prefix and the load continues; the entire load doesn't abort because one constraint / view / proc fails. Deferred-computed-column failures (phase 8, for the rare UDF-forward-ref table) use a `"Deferred: …"` prefix instead, so the `Load_AW_No_Per_Element_Failures` guard test stays meaningful — it would otherwise spuriously fire on known unmodeled-function gaps.

One pre-existing divergence surfaces as an "extra" element: AW's system-named UNIQUE constraint on `Production.Document.rowguid` is scripted anonymously (name in an annotation) by DacFx normally, but *named* once the table has a full-text index — and the simulator's auto-generated constraint name (FNV-based) differs from real's object-id-derived one (a documented quirk), so the named form doesn't byte-match. Doesn't block real import (verified: aw-export re-imports into a live SQL Server 2025, both view indexes present at index_id 1 / CLUSTERED / unique).
