1	Group	Id	Mutation	File	Line	TestsThatFailed	Configurations	Detected	Note
2	access	M1	Drop the WriteError for AddAceError in the retry-failed catch (swallows the error of the item)	AddAccess.cs	149	Add-NTFSAccess PathComplex: one AddAceError for the blocked path, unchanged, -PassThru only for the changed path	ElevatedDesktop, ElevatedCore	True
3	access	M2	Remove the continue after RemoveAceError in the retry-failed catch (-PassThru writes for the failed item too)	RemoveAccess.cs	166	Remove-NTFSAccess PathComplex: one RemoveAceError for the blocked path, unchanged, -PassThru only for the changed path	ElevatedDesktop, ElevatedCore	True
4	access	M3	Change the category of ClearAclError from WriteError to InvalidOperation in the retry-failed catch	ClearAccess.cs	89	Clear-NTFSAccess: ReadFileError and ClearAclError, each by category and target	ElevatedDesktop, ElevatedCore	True
5	access	M4	Change the category of ReadFileError from OpenError to ReadError	GetAccess.cs	96	Get-NTFSAccess Path: the error of a missing path by category and target	ElevatedDesktop, ElevatedCore	True
6	access	M5	Invert the orphan predicate (IsNullOrEmpty to not IsNullOrEmpty), so that it keeps resolvable accounts	GetOrphanedAccess.cs	75	All three Get-NTFSOrphanedAccess tests (Path state, Path error and pipeline, SD)	ElevatedDesktop, ElevatedCore	True
7	access	M6	Invert the -Account filter (== to !=)	SimpleAccessCmdlets.cs	126	Get-NTFSSimpleAccess SD: filter and partition a descriptor like -Path	ElevatedDesktop, ElevatedCore	True
8	access	M7	Default -Account changed from the current user to S-1-1-0 (Everyone)	GetEffectiveAccess.cs	15	Get-NTFSEffectiveAccess Path (allowed right present) and SecurityDescriptor (follows an in-memory change)	ElevatedDesktop, ElevatedCore	True
9	access	M8	Gate the -AppliesTo scope conversion on a condition that is never true (EndsWith("Simple") to EndsWith("NeverSimple")), so that the Simple sets keep default flags	AddAccess.cs	113	Add-NTFSAccess PathSimple: scope the entry of the next path	ElevatedDesktop, ElevatedCore	True
10	audit	M1	Delete the WriteError(ReadFileError) call, keep the continue	AddAudit.cs	129	Add-NTFSAudit pipeline by Path (both rows)	ElevatedDesktop, ElevatedCore	True
11	audit	M2	Invert removeSpecific in the primary Remove call	RemoveAudit.cs	151	Remove-NTFSAudit pipeline by Path (PathSimple row), narrow-rights test	ElevatedDesktop, ElevatedCore	True
12	audit	M3	DisableAuditInheritance(item, true) to (item, false)	ClearAudit.cs	74	Clear-NTFSAudit -DisableInheritance state test	ElevatedDesktop, ElevatedCore	True
13	audit	M4	ErrorCategory OpenError to NotSpecified in the generic catch of the SACL read	GetAudit.cs	112	Get-NTFSAudit without the Security privilege: category test	BasicDesktop, BasicCore	True	Invisible in the elevated configurations: the mutated line is reached only without the Security privilege
14	audit	M5	ErrorId ReadError to ReadFileError for a missing path	Get-OrphanedAudit.cs	43	Get-NTFSOrphanedAudit pipeline by Path	ElevatedDesktop, ElevatedCore	True
15	audit	M6	ErrorCategory InvalidData to InvalidOperation in TestAuditSection	BaseCmdlets.cs	159	All 7 cross-cutting rows and the Get-NTFSAudit SD pipeline test (8 failures)	ElevatedDesktop, ElevatedCore	True
16	audit	M7	Delete the continue after the ReadFileError WriteError	RemoveAudit.cs	141	Remove-NTFSAudit pipeline by Path (both rows; cascades to a RemoveAceError NullReferenceException)	ElevatedDesktop, ElevatedCore	True
17	audit	M8	Invert IsNullOrEmpty in the orphaned-entry filter	Get-OrphanedAudit.cs	74	Get-NTFSOrphanedAudit pipeline by Path, pipeline SD, direct SD (3 failures)	ElevatedDesktop, ElevatedCore	True
18	audit	M9	Disable the -AppliesTo to flags conversion for the Simple sets (if (false && ...))	AddAudit.cs	114	None of the new tests	ElevatedDesktop, ElevatedCore	False	Masked on a file target: AddFileSystemAuditRule forces InheritanceFlags None and PropagationFlags None for a file. PermissionScopes.Tests.ps1 (folder targets) catches the same mutation with 24 failures
19	inheritance	1	Disable-NTFSAccessInheritance ignores -RemoveInheritedAccessRules	DisableAccessInheritance.cs	80	4 of 8 rows of the DACL protected-flag test	ElevatedDesktop, ElevatedCore	True
20	inheritance	2	Enable-NTFSAccessInheritance ignores -RemoveExplicitAccessRules	EnableAccessInheritance.cs	80	2 of 8 rows of the DACL protected-flag test	ElevatedDesktop, ElevatedCore	True
21	inheritance	3	GetFileSystemInheritanceInfo(item) inverts the reported access flag	FileSystemInheritanceInfo.cs	71	8 tests: ModifySdError rows, the RestoreOwnerError of Set-NTFSInheritance, two piped rows, Get-NTFSInheritance pipe, the Set-NTFSInheritance round trip	ElevatedDesktop, ElevatedCore	True
22	inheritance	4	Get-NTFSOwner -SecurityDescriptor always returns the owner of the first descriptor	GetOwner.cs	86	Get-NTFSOwner -SecurityDescriptor, piped and passed directly	ElevatedDesktop, ElevatedCore	True
23	inheritance	5	Set-NTFSOwner -SecurityDescriptor always sets the owner of the first descriptor	SetOwner.cs	104	Set-NTFSOwner -SecurityDescriptor, after the test got a direct multi-element array call	ElevatedDesktop, ElevatedCore	True	Not detected by the pipeline-only test: the pipeline rebinds the list to one element per item, which hides an index bug. The test was strengthened with a direct call with an array and the mutation was detected
24	inheritance	6	InvokeAsOwner swallows the error of the restore of the owner	BaseCmdlets.cs	344	The 3 RestoreOwnerError rows	ElevatedDesktop, ElevatedCore	True
25	inheritance	7	Disable-NTFSAuditInheritance -Path loses ValueFromPipeline (keeps ValueFromPipelineByPropertyName)	DisableAuditInheritance.cs	16	None of the new tests	ElevatedDesktop, ElevatedCore	False	Get-ChildItem2 objects have a FullName property, so the binding by property name alone still binds them; only a bare string piped by value would show it
26	inheritance	8	Get-NTFSSecurityDescriptor reports NotSpecified instead of OpenError for a missing path	GetSecurityDescriptor.cs	48	OpenError for a path that does not exist	ElevatedDesktop, ElevatedCore	True
27	inheritance	9	GetFileSystemInheritanceInfo(sd) inverts the reported audit flag	FileSystemInheritanceInfo.cs	80	Set-NTFSInheritance -SecurityDescriptor: both flags in one call	ElevatedDesktop, ElevatedCore	True
28	inheritance	10	Set-NTFSInheritance -AccessInheritanceEnabled loses ValueFromPipelineByPropertyName	SetInheritance.cs	42	Restore a saved inheritance state through the pipeline	ElevatedDesktop, ElevatedCore	True
29	items	M1	RemoveItem2 catch no longer writes DeleteError for an IOException	RemoveItem2.cs	101	Remove-Item2 pipeline test (expected 1 error, got 0)	ElevatedDesktop, ElevatedCore	True
30	items	M2	GetFileHash2 generic catch no longer continues, so a null hash is written after the error	GetFileHash2.cs	113	Get-FileHash2 locked file first (expected 1 result, got 2)	ElevatedDesktop, ElevatedCore	True
31	items	M3	GetItem2.Path loses ValueFromPipeline	GetItem2.cs	13	Get-Item2 pipeline test	ElevatedDesktop, ElevatedCore	True
32	items	M4	RemoveItem2.Path loses ValidateNotNullOrEmpty	RemoveItem2.cs	16	All 4 rows of the Remove-Item2 empty-path test	ElevatedDesktop, ElevatedCore	True	A recursive-delete guard; the test acts only inside its own disposable sandbox folder
33	items	M5	GetDiskSpace.DriveLetter loses Position = 1	GetDiskSpace.cs	14	Get-DiskSpace positional test	ElevatedDesktop, ElevatedCore	True
34	items	M6	GetFileHash2.Algorithm setter ignores the value and forces SHA256	GetFileHash2.cs	34	Get-FileHash2 pipeline and Algorithm test (MD5 assertion)	ElevatedDesktop, ElevatedCore	True
35	items	M7	NewSymbolicLink no longer returns after the ResourceExists error and falls through to the create attempt	NewSymbolicLink.cs	80	New-NTFSSymbolicLink success after a failure (expected 1 error, got 2)	ElevatedDesktop, ElevatedCore	True
36	items	M8	DisablePrivileges off by one: Count() == 0 to Count() == 1, which suppresses the error when nothing is enabled	OtherCmdlets.cs	100	Disable-Privileges error-path test	ElevatedDesktop, ElevatedCore	True
