docs(coverage): drop four environments from scope and record the AppliesTo cause
The maintainer decided on 2026-10-11 that Server Core, ARM64, a localized
operating system, and non-Windows file servers are not needed by the audience
of the tool. They leave the open items, the completion matrix, and the limits
of the report, and Decision 25 records the choice (Decision 23 and #34 are not
changed).
Open item 3 of the report now gives the cause of the dropped AppliesTo for a
path: the default parameter set PathComplex wins when a piped object satisfies
its mandatory parameters. A stand-alone model with the four sets and no default
binds PathSimple for an object with AppliesTo and keeps every named call; the
real cmdlets were not changed. debugging-insights.md keeps the lesson.

with `OSWin11E` started shortly before the sequence (it shuts down an hour
after its start), and `Test-MatrixCleanup.ps1 -Mode Verify -Machine
OSFile19,OSFile22,OSFile25,OSCore25,OSWin11E` after it. The address
`192.168.12.26` is not in the hosts file of the host (the matrix lab uses
.10, .11, .12, .19, .22, and .25).
- **What it can find.** Server Core has no shell and no Desktop Experience
components; the module is .NET Framework 4.5.2 code with Win32 calls, so a
difference would show in the import, in AlphaFS, or in the privilege code. It
can not find a difference of a localized system.
### ARM64
No reproduction exists. The crash of PowerShell 7.6.1 under x64 emulation had
no module frames, and native x64 CI did not reproduce it (`progress.md`, open
item 5). It stays open.
Not tested, and out of scope by the decision below: a localized operating
system (no such image exists: the ISO files are English), the names of built-in
accounts in other languages, and the localized texts of Windows errors. The
review found one test that depends on a localized text, the comparison of
`Get-Privileges` with the State column of `whoami /priv` in
`ParameterSets.Items.Tests.ps1`; it compares the state now only where `whoami`
prints the English words.
### Out of scope: Server Core, ARM64, a localized system, non-Windows servers
The maintainer decided on 2026-10-11 to forget these four environments: the
audience of the tool does not need them, so they are not open items, and no
plan, deployment, or test of this work covers them (decision 22 below, Memory
Bank Decision 25). The Server Core plan that this section had
(image index 3 of the Server 2025 ISO, about 12 GB, under an hour for the
machine) was dropped with the decision and stays in the history of this file;
nothing was deployed. The ARM64 crash of PowerShell 7.6.1 under x64 emulation
had no module frames and was never reproduced on native x64.

PowerShell: when a piped object satisfies the mandatory parameters of the
default set, the binder settles on it and never tries a parameter that
belongs to another set. Without `DefaultParameterSetName`, a model with the
same four sets binds `PathSimple` for an object with `AppliesTo` and
`PathComplex` for one without, and every named call resolves as before
(`E\probes\p-parameterset-binding*.ps1` and their outputs; the real
cmdlets were not changed or tested). The default is a leftover: at 4.2.6
`AppliesTo` was optional and the sets overlapped, and `4b1abc9` made it
mandatory so that the Complex sets win without it. Intended or not? Leaving
it is a documented limit; removing the default is a change of four cmdlet
attributes with a new error for an object that carries `AppliesTo` and
`InheritanceFlags` both.
