Merge Risk: 🟡 Moderate · up to Validation-only receipts can incorrectly attest an arbitrary bundle's SDK provenance, undermining qualification evidence. A concurrent retained-owner probe can also fail instead of reporting its diagnostic result.

Do not attribute workspace restore metadata to an existing bundle.
In validation-only mode, Get-ResolvedSdkPackage reads the version and sha512 from the workspace project.assets.json. The function checks that version against the requested version, but it does not match that package to the supplied bundle's CheatEngine.SDK.dll. A different bundle that passes the layout checks can therefore receive unrelated package provenance. Match the supplied DLL to an approved package, or mark SdkPackage as unverified in validation-only mode.

Use the CompareExchange result for the losing path.
If ReleaseOwner or RecordDisabling clears s_retainedOwner after the failed CompareExchange, the later Volatile.Read can return null. DescribeOwner then throws NullReferenceException.
Proposed fix
- if (Interlocked.CompareExchange(ref s_retainedOwner, owner, null) is null)
+ ITargetMemoryLease? retained = Interlocked.CompareExchange(ref s_retainedOwner, owner, null);

Follow-up to #49 and #28. No controlled Cheat Engine 7.7 x64 host or authorised disposable targets were available for this task, so this PR provides preparation and reproducible build/package-layout evidence only. It does not claim a live coexistence, collision, target-switch, retained-owner, or side-by-side SDK qualification.
