+<#
+.SYNOPSIS
+    Local twin of the "Check profiles" CI job (.github/workflows/check_profiles.yml), for Windows.
+
+.DESCRIPTION
+    The Windows counterpart of scripts/check_profile.sh, and kept deliberately close to it.
+
+    Runs the same five checks, in the same order, with the same validator flags, and with the
+    same semantics: every check runs even after an earlier one fails (the workflow's
+    continue-on-error), then the script exits non-zero once at the end.
+
+        extra_json_check              scripts/orca_extra_profile_check.py
+        validate_system               validator -p <profiles> -l <level>
+        validate_slice                validator -p <profiles> -s -l <level>
+        validate_filament_subtypes    validator -p <profiles> -l <level> -f
+        validate_custom               validator against every released custom-preset fixture
+
+    Everything that has to be downloaded - the profile validator and the custom-preset fixture
+    archives - lands under <repo>\.test\check_profiles and is reused on the next run. That
+    directory also holds one log per check plus a copy of the comment CI would post on the PR.
+
+    resources\profiles\user, which the validator creates as its data dir but a CI checkout never
+    has, is moved aside for the duration of the run and restored on exit. Only one run per work
+    dir at a time.
+
+    x64 and ARM64 hosts are both supported. A locally built validator is chosen by the machine
+    type in its PE header rather than by the name of its build tree, so build\ (x64) and
+    build-arm64\ side by side resolve correctly; the published nightly is x64 only and runs
+    under emulation on ARM64.
+
+.PARAMETER ProfilesDir
+    Profile tree to validate (default: resources\profiles). extra_json_check always looks at the
+    tree next to the script, so this only redirects the validator checks.
+
+.PARAMETER Validator
+    OrcaSlicer_profile_validator.exe to use; also $env:ORCA_PROFILE_VALIDATOR. Default: the local
+    build*\ Release build (then RelWithDebInfo, MinSizeRel, Debug) for this architecture, else
+    the nightly release build is downloaded.
+
+.PARAMETER Download
+    Ignore local builds and use the downloaded nightly validator.
+
+.PARAMETER Refresh
+    Re-download the validator and fixtures instead of using the cache.
+
+.PARAMETER WorkDir
+    Downloads, logs and fixture trees (default: .test\check_profiles). Point it somewhere short,
+    such as D:\t, if a fixture tree trips Windows' 260-character path limit.
+
+.PARAMETER LogLevel
+    Validator log level (default: 2, as in CI).
+
+.PARAMETER Checks

+  validate_system               validator -p <profiles> -l <level>

+
+Options:
+  -p, --profiles DIR   profile tree to validate (default: resources/profiles)
+      --validator BIN  OrcaSlicer_profile_validator to use; also \$ORCA_PROFILE_VALIDATOR.
+                       Default: the local build*/ Release build (then RelWithDebInfo, then
+                       Debug) for this architecture, else the nightly release build is
+                       downloaded for this platform
+      --download       ignore local builds and use the downloaded nightly validator
+      --refresh        re-download the validator and fixtures instead of using the cache
+      --work-dir DIR   downloads, logs and fixture trees (default: .test/check_profiles)
+  -l, --log-level N    validator log level (default: ${LOG_LEVEL}, as in CI)
+  -h, --help           show this help

+.SYNOPSIS
+    Tests build_win.bat's option handling and the commands it generates.
+
+.DESCRIPTION
+    Cases run the script with --dry-run, so nothing is configured, built or
+    deleted and the suite finishes in seconds. Each case asserts on the exit
+    code and on the command lines the script echoes.
+
+    Adding a case means adding one row to $cases. A bare string starts a new
+    group. Defaults: ExpectExit is 0 and --dry-run is appended, so a row only
+    states what is unusual about it.
+
+        Name        what the case proves, in words
+        Args        arguments, as an array
+        ExpectExit  expected exit code            (default 0)
+        DryRun      append --dry-run              (default $true)
+        First       regex the first output line must match
+        Env         environment for this case only
+        Contains    literal strings the output must have
+        NotContains literal strings it must not have
+        Match       regexes; each must match at least one output line
+        NotMatch    regexes; none may match any output line
+        NotExists   paths that must not exist after the case runs
+
+.PARAMETER Name
+    Run only the cases whose name matches this regex. Headings with no
+    matching case are not printed, and a pattern that matches nothing is a
+    failure rather than an empty pass.
