+# AAA Test Pattern Convention
+
+> **TL;DR**: Use comments as AAA markers inside ordinary `New-TestStep -Body { … }` blocks. Reserve the heavyweight `Invoke-AAATest` cmdlet (with separate `-Arrange` / `-Act` / `-Assert` / `-Cleanup` scriptblocks) ONLY for tests that genuinely need automatic cleanup-runs-always semantics or phase-tagged failure attribution.
+
+---
+
+## Motivation
+
+We considered two ways to enforce the Arrange-Act-Assert-Cleanup pattern across module checklists:
+
+### Option A — Lightweight: comments-as-AAA markers (CHOSEN)
+
+```powershell
+New-TestStep -Tag direct -Id 'CmdPal_Calculator_CopyOnEnter' `
+    -Name "Calculator copies '7+5' result on Enter" -Body {
+    # ── Arrange ──
+    $orig = Get-ClipboardSafe
+    $sentinel = "WHATEVER"
+    Set-ClipboardSafe $sentinel
+
+    # ── Act ──
+    winapp ui set-value 'MainSearchBox' '7+5'
+    winapp ui invoke 'PrimaryCommandButton'
+
+    try {
+        # ── Assert ──
+        $clip = Get-ClipboardSafe
+        if ($clip -ne '12') { throw "expected '12', got '$clip'" }
+    }
+    finally {
+        # ── Cleanup ──
+        Set-ClipboardSafe $orig
+    }
+}
+```
+
+Pros:
+- ✅ **Variables flow naturally top-to-bottom** — no `param($ctx)` ceremony, no `$ctx.foo` rewrites
+- ✅ **`try/catch/finally` works as PowerShell intends** — no wrapper to fight
+- ✅ **Reads like the test you'd write** — comments document intent without enforcing structure
+- ✅ **Existing tests already follow this de-facto** — most just lack the comment markers
+- ✅ **Trivial migration** — add comment lines, no code changes
+- ✅ **Works with `-Id` + `Set-AAAFilter`** — full filter UX without extra wrapper
+
+Cons:
+- ⚠ Comment markers are **convention not enforcement** — a sloppy contributor could mis-place them
+- ⚠ Cleanup-always semantics depend on `try/finally` discipline (easy to forget in a new test)
+
+### Option B — Heavyweight: `Invoke-AAATest` cmdlet with separate scriptblocks
+
+```powershell
+Invoke-AAATest -Tag direct -Id 'CmdPal_Calculator_CopyOnEnter' `
+    -Name "Calculator copies '7+5' result on Enter" `
+    -Arrange {
+        $orig = Get-ClipboardSafe
+        $sentinel = "WHATEVER"
+        Set-ClipboardSafe $sentinel
+        @{ orig = $orig; sentinel = $sentinel }   # return → becomes $ctx
+    } `
+    -Act { param($ctx)
+        winapp ui set-value 'MainSearchBox' '7+5'
+        winapp ui invoke 'PrimaryCommandButton'
+    } `
+    -Assert { param($ctx)
+        $clip = Get-ClipboardSafe
+        if ($clip -ne '12') { throw "expected '12', got '$clip'" }
+    } `
+    -Cleanup { param($ctx)
+        Set-ClipboardSafe $ctx.orig
+    }
+```
+
+Pros:
+- ✅ **Cleanup ALWAYS runs** (wrapped in `finally`) — can't forget it
+- ✅ **Phase-tagged failure messages** — "Arrange: …" vs "Act: …" vs "<bare>" for Assert
+- ✅ Mechanically reviewable (each phase isolated)
+
+Cons:
+- ❌ **Each scriptblock is its own scope** — must thread state via `$Context` hashtable
+- ❌ Every fixture variable becomes `$ctx.foo` (5 vars × 3 phases = 15 rewrites per test)
+- ❌ Easy to forget `param($ctx)` line in subsequent blocks → silent `$null` references
+- ❌ Easy to forget the implicit `@{...}` return in `-Arrange` → empty `$Context`
+- ❌ Adds significant verbosity for tests with no real cleanup needs
+
+---
+
+## Decision
+
+**Use Option A (comments-as-AAA-markers) for ALL module checklists** going forward.
+
+**Keep Option B (`Invoke-AAATest`) available** for the rare tests that actually need:
+- True cleanup-always semantics that can't be expressed in a one-line `finally`
+- Phase-tagged failure attribution for triage (e.g. tests that set up flaky fixtures and want "Arrange: timeout" vs "Assert: wrong output" prefixes in the report)
+
+CmdPal and Peek hand-written examples already use Option B for their fixture-heavy tests. They serve as references for when Option B is genuinely warranted.
+
+---
+
+## Conventions
+
+### Test ID format (REQUIRED)
+
+Every `New-TestStep` and `Invoke-AAATest` call gets `-Id '<Module>_<Feature>_<ExpectedBehavior>'`:
+
+```powershell
+New-TestStep -Tag direct -Id 'Hosts_AddEntry_ResolvesNewName' ...
+New-TestStep -Tag direct -Id 'CmdPal_Calculator_ReturnsFourForTwoPlusTwo' ...
+```
+
+Why: stable handle for `-Only` / `-Skip` filtering, survives Name reword.
+
+### Comment markers (CONVENTION)
+
+Inside each `-Body { ... }`:
+
+```powershell
+New-TestStep ... -Body {
+    # ── Arrange ──
+    <fixture setup, snapshots, file backups>
+
+    # ── Act ──
+    <drive the UI / system under test>
+
+    try {
+        # ── Assert ──
+        <verify outcome; throw on failure>
+    }
+    finally {
+        # ── Cleanup ──
+        <restore state, kill spawned processes>
+    }
+}
+```
+
+Place markers as PowerShell comments (`#`) at column 4. The `try/finally` is OPTIONAL — only add it when the test mutates external state that must be restored. For pure-read tests (settings.json schema check, process-presence assertion), skip the try/finally entirely:
+
+```powershell
+New-TestStep -Tag direct -Id 'Peek_Process_RunningWhenEnabled' ... -Body {
+    # ── Act ──
+    $proc = Get-Process PowerToys.Peek.UI -ErrorAction SilentlyContinue
+
+    # ── Assert ──
+    if (-not $proc) { throw "Peek not running" }
+}
+```
+
+### Filter support (REQUIRED)
+
+Every checklist's `param()` block must declare `-Only` and `-Skip`:
+
+```powershell
+[CmdletBinding()]
+param(
+    [string]$OutputDir = (Join-Path $env:TEMP 'winappcli-<module>-checklist'),
+    [string[]]$Only = @(),
+    [string[]]$Skip = @()
+)
+$ErrorActionPreference = 'Stop'
+Import-Module ...\WinAppCli.PowerToys.psd1 -Force
+Reset-TestSuite
+
+# Filter normalisation (accept comma/semicolon-separated single string)
+function _SplitFilter([string[]]$xs) {
+    $out = New-Object System.Collections.Generic.List[string]
+    foreach ($x in @($xs)) {
+        if ([string]::IsNullOrWhiteSpace($x)) { continue }
+        foreach ($piece in $x -split '[,;]') {
+            $t = $piece.Trim().Trim("'`"")
+            if ($t) { $out.Add($t) }
+        }
+    }
+    @($out)
+}
+$Only = _SplitFilter $Only
+$Skip = _SplitFilter $Skip
+Set-AAAFilter -Only $Only -Skip $Skip
+```
+
+Usage:
+
+```powershell
+pwsh -File <module>-checklist.ps1                                  # all tests
+pwsh -File <module>-checklist.ps1 -Only 'Hosts_*Add*'              # subset
+pwsh -File <module>-checklist.ps1 -Skip 'Hosts_*Quit*'             # skip flake
+pwsh -File <module>-checklist.ps1 -Only 'A,B,C' -Skip '*Slow*'     # CSV
+```
+
+### When to use `Invoke-AAATest` instead
+
+Use the heavyweight `Invoke-AAATest` cmdlet when ALL of these are true:
+
+1. The test has **fixtures that absolutely must be cleaned up** even if the assert throws (e.g. clipboard restore, settings.json restore, child-process kill)
+2. The cleanup logic is **complex enough** that an inline `try/finally` is error-prone
+3. You want **phase-tagged failure messages** in the report (rare — usually the Assert message alone is clear enough)
+
+For the 99% case where you have a 1-line cleanup or no cleanup at all, **prefer `New-TestStep` with comment markers**.
+
+---
+
+## Examples by complexity
+
+### Pure-read test — no Cleanup needed, no comments needed for trivial 2-liners
+
+```powershell
+New-TestStep -Tag direct -Id 'CmdPal_AppX_Installed' -Name "..." -Body {
+    $appx = Get-AppxPackage -Name 'Microsoft.CommandPalette' -EA SilentlyContinue
+    if (-not $appx) { throw "Microsoft.CommandPalette AppX not installed" }
+}
+```
+
+### Multi-step test — comments help readability
+
+```powershell
+New-TestStep -Tag direct -Id 'Module_Feature_Behavior' -Name "..." -Body {
+    # ── Arrange ──
+    $fixture = Get-Fixture
+    $snapshot = Snapshot-State
+
+    # ── Act ──
+    Drive-Ui $fixture
+
+    # ── Assert ──
+    $result = Read-Result
+    if ($result -ne 'expected') { throw "got '$result'" }
+
+    # No -Cleanup needed; nothing to undo
+}
+```
+
+### State-mutating test — try/finally for cleanup discipline
+
+```powershell
+New-TestStep -Tag direct -Id 'Hosts_AddEntry_ResolvesNewName' -Name "..." -Body {
+    # ── Arrange ──
+    $orig = Backup-HostsFile
+    Add-HostsEntry "1.2.3.4" "test.local"
+
+    try {
+        # ── Act + Assert ──
+        $resolved = Resolve-DnsName "test.local"
+        if ($resolved.IPAddress -ne "1.2.3.4") {
+            throw "expected 1.2.3.4, got $($resolved.IPAddress)"
+        }
+    }
+    finally {
+        # ── Cleanup ──
+        Restore-HostsFile $orig
+    }
+}
+```
+
+### Heavy-fixture test — `Invoke-AAATest` justified
+
+```powershell
+Invoke-AAATest -Tag direct -Id 'CmdPal_Calculator_CopiesResultOnEnter' -Name "..." `
+    -Arrange {
+        $orig     = Get-ClipboardSafe
+        $sentinel = "WINAPPCLI_$(Get-Random)"
+        Set-ClipboardSafe $sentinel
+        @{ orig = $orig; sentinel = $sentinel; expected = '12' }
+    } `
+    -Act { param($ctx)
+        Invoke-CmdPalQuery '7+5'
+        # … invoke Copy …
+    } `
+    -Assert { param($ctx)
+        $after = Get-ClipboardSafe
+        if ($after -ne $ctx.expected) { throw "got '$after'" }
+    } `
+    -Cleanup { param($ctx)
+        if ($ctx.orig) { Set-ClipboardSafe $ctx.orig }
+    }
+```
+
+Justified because: clipboard MUST be restored even if Assert throws (we polluted it with a sentinel); explicit phase tags help triage (was it the seeding that failed, or the actual assert?); the test runs in CI so visible cleanup hygiene matters.
+
+---
+
+## Migration plan
+
+**No mass-conversion script.** Apply this convention test-by-test as you touch a module:
+
+1. When **adding** a new test → use the convention from the start
+2. When **fixing** an existing test → add the comment markers + Id while you're in there
+3. When **a module ships a new release** → optionally pass through and add markers + Ids to existing tests (good time, you're already reading them)
+
+This keeps churn minimal and respects the working principle that **the tests already work** — we just want the new ones to be more readable.

+# winappcli — UI test suite for PowerToys Command Palette
+
+A PowerShell-only UI test suite that drives the PowerToys **Command Palette**
+(CmdPal) module via Microsoft's
+[winappCli](https://github.com/microsoft/winappCli) (Windows UI Automation
+client) and asserts both the on-disk settings schema and live UI behaviour.
+
+This folder is a focused example of the winappcli approach: a single,
+fully-translated module checklist (Command Palette) plus the shared helper
+module it depends on. It is intended as a template for porting the manual
+release-checklist boxes of other modules into runnable assertions.

+```
+
+## Prerequisites
+
+1. **winappCli v0.3.1** (or newer):
+   ```powershell
+   winget install --id Microsoft.WinAppCli --source winget
+   winapp --version                  # expect >= 0.3.1; reopen the shell if not on PATH
+   ```
+2. **PowerShell 7.2+** — the suite uses `#Requires -Version 7.0`:
+   ```powershell
+   winget install --id Microsoft.PowerShell --source winget
+   pwsh -Version
+   ```
+3. **PowerToys** installed, with Command Palette (CmdPal 0.99+ ships as a
+   bundled AppX) enabled:
+   ```powershell
+   winget install --id Microsoft.PowerToys --source winget
+   # Then: PowerToys Settings → Command Palette → toggle ON
+   Get-AppxPackage Microsoft.CommandPalette   # expect InstallLocation output
+   ```
+4. **Windows Search service** running (one Files test needs the indexer):
+   ```powershell
+   Get-Service WSearch               # expect Status='Running'
+   ```
+
+> The suite runs against an **installed** PowerToys (via winget / AppX); it does
+> not build the product from this repo.
+
+## Quick start
+
+Smoke test to confirm the environment is wired up (< 1 second):
+
+```powershell
+cd <repo>\tools\winappcli
+pwsh -File .\modules\command-palette-checklist.ps1 -Only 'CmdPal_Installed_*'
+# expect: Report: PASS 1 · FAIL 0
+```
+
+Full suite (~15 min wall clock, AppX-state-dependent):
+
+```powershell
+pwsh -File .\modules\command-palette-checklist.ps1
+```
+
+Filtered / faster runs:
+
+```powershell
+pwsh -File .\modules\command-palette-checklist.ps1 -Only 'CmdPal_Calculator_*'
+pwsh -File .\modules\command-palette-checklist.ps1 -Skip 'CmdPal_Stability_*'
+pwsh -File .\modules\command-palette-checklist.ps1 -Tag schema      # CI gate, ~2s
+pwsh -File .\modules\command-palette-checklist.ps1 -Tag list        # print the tag map
+```
+
+### Tag system
+
+`-Tag` expands to a set of `-Only` patterns so test classes can be run without
+remembering individual IDs:
+
+| Tag | Meaning |
+|---|---|
+| `schema`      | pure file/JSON reads, no UI driving (~1s total) |
+| `functional`  | provider e2e tests that drive CmdPal UI (~3 min) |
+| `mutation`    | edit settings.json + restart AppX + verify (~80s) |
+| `stability`   | regression guards (rapid typing, separator nav) |
+| `integration` | PowerToys ↔ CmdPal integration tests |
+| `pin`         | Dock pin tests |
+| `bootstrap`   | install / settings-page / runtime verification |
+| `ci`          | composite: `schema` + `bootstrap` |
+| `nightly`     | composite: everything except destructive |
+
+## Common gotchas
+
+| Symptom | Cause | Fix |
+|---|---|---|
+| `winapp: command not found` | WinAppCli installed but PATH stale | Reopen the shell; or `$env:PATH += ';' + "$env:LOCALAPPDATA\Microsoft\WindowsApps"` |
+| Many SKIPs with "CmdPal not found via list-windows" | CmdPal AppX not enabled / not running | PowerToys Settings → Command Palette → toggle on; or press Alt+Space |
+| `Files_OpenActionForNonExecutable` fails with ENVIRONMENT-REQUIRED | Windows Search service stopped | `Start-Service WSearch` |
+| Elevated PT + winappCli SendInput hits "access denied" | UIPI blocks elevated → non-elevated AppX | Run the test in non-elevated pwsh; or use `Send-PtKeyToWindow` (PostMessage path) |
+| Stability test times out on first run | Cold AppX response latency | Re-run; warm AppX typically finishes in ~60s |
+
+## How to debug a single test
+
+Use the orchestrator's `-Only` filter (accepts wildcards and arrays):
+
+```powershell
+.\modules\command-palette-checklist.ps1 -Only 'CmdPal_SettingsUI_Dock_EnableDockShowsPowerDockWindow'
+.\modules\command-palette-checklist.ps1 -Only 'CmdPal_Calculator_*','CmdPal_Settings_*'
+```
+
+Recommended breakpoint workflow is VS Code with the
+[PowerShell extension](https://marketplace.visualstudio.com/items?itemName=ms-vscode.PowerShell):
+open a test file (e.g. `modules\cmdpal\24-SettingsUI-e2e.ps1`), press **F9** on
+a line, then run the `-Only` command in the integrated terminal. For non-VS-Code
+workflows, drop a `Wait-Debugger` statement or use `Set-PSBreakpoint`.
+
+## Test convention
+
+All tests follow the Arrange / Act / Assert / Cleanup pattern and use the shared
+`Assert-*` vocabulary from `modules\_shared\Assertions.ps1`. See
+[`AAA-PATTERN-CONVENTION.md`](AAA-PATTERN-CONVENTION.md) for the full rationale,
+and [`modules\command-palette-099-coverage-gaps.md`](modules/command-palette-099-coverage-gaps.md)
+for tests intentionally deferred.

+function Wait-Until {
+    <#
+    .SYNOPSIS
+    Generic event-driven wait primitive — repeatedly evaluates Condition
+    until it returns truthy, returns that value, or throws on timeout.
+
+    .DESCRIPTION
+    Modelled on Selenium's WebDriverWait / Java's FluentWait:
+
+        // Selenium C#
+        WebDriverWait wait = new WebDriverWait(driver, TimeSpan.FromSeconds(10));
+        IWebElement el = wait.Until(d => d.FindElement(By.Id("foo")));
+
+        // Java FluentWait
+        Wait<WebDriver> wait = new FluentWait<>(driver)
+            .withTimeout(Duration.ofSeconds(30))
+            .pollingEvery(Duration.ofMillis(500))
+            .ignoring(NoSuchElementException.class);
+        WebElement foo = wait.until(d -> d.findElement(By.id("foo")));
+
+    Use this everywhere a test would otherwise hand-roll a deadline +
+    polling + null/throw loop. The condition's return value is what
+    Wait-Until returns — so you both "wait for X" AND "fetch X" in one call.
+
+    .PARAMETER Condition
+    Scriptblock evaluated on each poll. Return any truthy value to succeed
+    (the value is returned by Wait-Until). Return $false / $null / empty
+    string to "not yet, keep polling".
+
+    .PARAMETER TimeoutMs
+    How long to keep retrying before throwing, in milliseconds. Default
+    10000 (10 s). Always milliseconds — there is no -TimeoutSec because
+    one unit is enough to remember.
+
+    .PARAMETER PollMs
+    Pause between condition evaluations. Default 200ms. Lower = faster
+    response when condition flips, higher CPU; higher = vice versa.
+
+    .PARAMETER Message
+    Prefix for the timeout exception message. Default 'Condition did not
+    become true'. Make it descriptive — it's the only signal you'll have
+    when a wait times out in CI logs.
+
+    .PARAMETER IgnoreException
+    When set, exceptions thrown by Condition are treated as "not yet, keep
+    polling" and the last exception is included in the timeout message if
+    the wait ultimately fails. Without this switch, the first exception
+    propagates immediately. Equivalent to Selenium's
+    FluentWait.ignoring(ExceptionType.class).
+
+    .EXAMPLE
+    # Wait up to 5s for a UIA element to exist; throw with descriptive message on timeout
+    $item = Wait-Until -TimeoutMs 5000 -Message "Calc result '4' not found" {
+        $r = winapp ui search '4' -w $cpHwnd --json 2>$null | ConvertFrom-Json
+        $r.matches | Where-Object { $_.type -eq 'ListItem' -and $_.name -eq '4' } | Select-Object -First 1
+    }
+
+    .EXAMPLE
+    # Wait for a property to stop being a stale default value
+    Wait-Until -TimeoutMs 3000 -PollMs 100 -Message "Primary stuck on home default" {
+        $pri = (winapp ui get-property 'PrimaryCommandButton' -w $h --json | ConvertFrom-Json).properties.Name
+        if ($pri -and $pri -ne 'Open in default browser') { return $pri }
+    }
+
+    .EXAMPLE
+    # Wait for a window to appear, ignoring transient "no such window" errors
+    $hwnd = Wait-Until -TimeoutMs 30000 -IgnoreException -Message "Settings did not open" {
+        (Get-Process MyApp -ErrorAction Stop).MainWindowHandle
+    }
+
+    .NOTES
+    GOTCHA: Wait-Until is unreliable for returning arrays from Condition.
+    Two reasons:
+      1. The "[array]/strip-to-last-element" line below was originally
+         intended to coerce implicit multi-value returns to a single value
+         for truthiness, but it ALSO strips intentional ,$arr comma-trick
+         returns down to the last element.
+      2. PowerShell function returns unroll arrays through the pipeline,
+         so even if Wait-Until returns an array intact, $x = Wait-Until {}
+         will turn a single-element array into a scalar.
+    If your Condition logically produces an array, use Wait-Until purely as
+    a presence check (Condition returns @(...).Count -gt 0) and re-fetch
+    the array in the caller AFTER Wait-Until returns. See e.g.
+    cmdpal/22-Navigation.tests.ps1 for the pattern.

+

+    want to widen their deadlines on slow boxes. Call once at the start
+    of a poll loop and multiply your deadline by it.
+
+    .EXAMPLE

+function Wait-StaysTrue {
+    <#
+    .SYNOPSIS
+    Negative-assertion wait primitive — polls Condition over a duration
+    and fails the FIRST time the condition becomes falsy.
+
+    .DESCRIPTION
+    The semantic opposite of Wait-Until. Use this when you need to assert
+    "X stays true for the next N seconds" — typically post-action liveness
+    checks ("after restarting AppX, the process must not crash within 4s").
+
+    A naive Start-Sleep + single check is WRONG for this on slow machines:
+    longer sleep = the crash window grows = test more likely to PASS
+    falsely. This helper polls every PollMs and fails as soon as a crash
+    is detected. The duration IS the assertion budget, not just padding.
+
+    Like Wait-Until, honors WINAPPCLI_SLOW_FACTOR by default — slow CI
+    runners get a wider observation window proportional to their slowdown.
+    Pass -NoSlowFactor to opt out.
+
+    .EXAMPLE
+    # Confirm CmdPal.UI survives 2 seconds after a settings restart.

+function Send-PtKeyToWindow {
+    <#
+    .SYNOPSIS
+    Post a single key press (WM_KEYDOWN + WM_KEYUP) directly to a target HWND
+    via PostMessage. Unlike Send-PtKey (which uses SendInput → kernel input queue),
+    PostMessage goes straight into the target window's message queue. This means:
+
+      - Does NOT require the target window to be foreground.
+      - Does NOT require the caller and target to share elevation level
+        (SendInput fails with ERROR_ACCESS_DENIED when an elevated test script
+        tries to send input to a non-elevated AppX like CmdPal — PostMessage
+        bypasses that UIPI restriction).
+      - Useful for selecting items in a ListView, dismissing dialogs, etc.,
+        without stealing focus from whatever the user is doing.
+
+    Caveat: some apps with custom raw-input loops (games, RDP clients) do not
+    process WM_KEYDOWN through their window proc and won't react. WinUI 3 and
+    classic Win32 apps generally do.
+
+    .PARAMETER Hwnd
+    Target window handle. Get this from `winapp ui list-windows --json`.
+    .PARAMETER Key
+    Key token: 'down', 'up', 'left', 'right', 'enter', 'esc', 'tab', etc.
+    Same vocabulary as Send-PtKey.
+    .PARAMETER HoldMs
+    Milliseconds between KEYDOWN and KEYUP. Default 30.
+
+    .EXAMPLE
+    Send-PtKeyToWindow -Hwnd $cpHwnd -Key 'down'    # navigate down 1 item without stealing focus

+# 09-SharedEvents.ps1 — invoke PowerToys modules via their named kernel events.
+#
+# Background
+# ----------
+# PowerToys' runner and module processes communicate via Win32 named Events
+# (see src/common/interop/shared_constants.h). When the user presses a hotkey,
+# the runner's centralized LLKH calls the module's `on_hotkey()` callback,
+# which usually just calls `SetEvent(m_hInvokeEvent)`. The module's UI process
+# (e.g. PowerToys.Peek.UI.exe, PowerToys.AlwaysOnTop.exe) waits on that named
+# Event with WaitForMultipleObjects and reacts when it's signalled.
+#
+# We can SetEvent these names directly from PowerShell. This is the proper,
+# deterministic way to drive PT modules from a script — far better than
+# simulating keyboard input because it bypasses:
+#   - foreground-window focus timing
+#   - UIPI integrity-level mismatches between elevated/medium-IL processes
+#   - LLKHF_INJECTED filtering (none of the events do this, but SendInput risks it)
+#   - the centralized LLKH's eligibility checks (e.g. Peek's "must be Explorer focused")
+#
+# Events live in the `Local\` namespace (per-session), so any process in the
+# same user session can open them — no admin needed.
+
+# Compile the SetEvent PInvoke surface once per session. .NET's
+# EventWaitHandle.OpenExisting works too, but raw OpenEvent + SetEvent gives
+# us better error messages.

+# 10-AAATest.ps1 — Arrange-Act-Assert-Cleanup test harness + generic UIA helpers.
+#
+# Implements the xUnit-style 4A pattern adapted for PowerShell + winappCli:
+#
+#   Arrange  → set up state, snapshot artifacts, spawn fixtures
+#              (return a hashtable; becomes the $Context for later phases)
+#   Act      → drive the UI under test (set-value, invoke, click, …)
+#   Assert   → verify the expected outcome (throw on failure)
+#   Cleanup  → restore state ALWAYS (runs in finally; errors here don't fail
+#              the test — they're warnings)
+#
+# Why this pattern:
+#   - 80% of UIA test code is state management + cleanup. Making the phases
+#     explicit forces consistent shape across modules.
+#   - When a test fails, the report identifies WHICH phase failed (the
+#     stack trace shows the Act block, not Cleanup).
+#   - Cleanup ALWAYS runs even if Act/Assert throws — no leaked notepads,
+#     no polluted clipboards, no sub-page traps for the next test.
+#   - Context flows through phases as a hashtable (no globals).
+#
+# All four blocks receive $Context as $args[0]; Arrange may return a
+# hashtable to seed the context. Example:
+#
+#   Invoke-AAATest -Name "Box L1024 ★ FULL: Calculator copies on Enter" `
+#     -Tag direct `
+#     -Arrange {
+#         @{ origClip = Get-ClipboardSafe ; sentinel = "SENTINEL_$(Get-Random)" }
+#     } `
+#     -Act {
+#         param($ctx)
+#         Set-ClipboardSafe $ctx.sentinel
+#         # … type 7+5, invoke Copy …
+#     } `
+#     -Assert {
+#         param($ctx)
+#         $clip = Get-ClipboardSafe
+#         if ($clip -ne '12') { throw "expected '12' got '$clip'" }
+#     } `
+#     -Cleanup {
+#         param($ctx)
+#         if ($ctx.origClip) { Set-ClipboardSafe $ctx.origClip }
+#     }

+    .SYNOPSIS

+    <#
+    .SYNOPSIS
+    Runs a single test using the Arrange-Act-Assert-Cleanup pattern. Wraps
+    New-TestStep so results land in the same report.
+
+    .PARAMETER Name
+    Short description of the test (printed and stored in report).
+    .PARAMETER Id
+    Optional short stable identifier (e.g. 'L1024-FULL', 'L1029-Walker'). Used
+    by Set-AAAFilter for selecting / skipping tests. ID is more stable than
+    Name for filtering — Name often gets reworded; Id should not.
+    .PARAMETER Tag
+    One of: direct, helper, visual, audio, skipped, info. Defaults to direct.
+    .PARAMETER SkipReason
+    If set, the test is recorded as SKIP and Arrange/Act/Assert/Cleanup are
+    not invoked.
+    .PARAMETER Ignore
+    Switch — equivalent to xUnit [Fact(Skip="…")] / [Ignore]. When present,
+    the test is recorded as SKIP with the IgnoreReason; Arrange/Act/Assert/
+    Cleanup are not invoked. Use this for known-flaky tests you want to
+    declaratively disable WITHOUT deleting the code or commenting it out.
+    .PARAMETER IgnoreReason
+    Required when -Ignore is set. Recorded in the report so reviewers know
+    why the test is disabled (e.g. "flaky on RDP — see issue #42").
+    .PARAMETER Arrange
+    Optional. Sets up state. Return a hashtable to seed the $Context shared
+    with Act / Assert / Cleanup. If omitted, Context starts as an empty hashtable.
+    .PARAMETER Act
+    Required. Drives the UI / system under test. Receives $Context as $args[0].
+    .PARAMETER Assert
+    Required. Verifies the expected outcome. Throw on failure. Receives $Context.
+    .PARAMETER Cleanup
+    Optional. Restores state. Runs in finally — ALWAYS executes, even if
+    Arrange/Act/Assert threw. Errors during Cleanup are emitted as warnings,
+    not test failures (the test has already failed if it got here).
+    Receives $Context as $args[0].
+
+    .NOTES
+    Skip/Ignore precedence:
+      1. -SkipReason (parameter set Skip) → SKIP "<reason>"
+      2. -Ignore                          → SKIP "ignored: <IgnoreReason>"
+      3. -Tag skipped                     → SKIP (legacy compatibility)
+      4. Set-AAAFilter -Only doesn't match → SKIP "filtered (--only=<pat>)"
+      5. Set-AAAFilter -Skip matches      → SKIP "filtered (--skip=<pat>)"
+      6. Otherwise                        → run all four phases
+
+    Failure semantics:
+      - Arrange throws  → test FAILS with detail "Arrange: <err>"; Cleanup still runs
+      - Act throws      → test FAILS with detail "Act: <err>"; Assert skipped; Cleanup runs
+      - Assert throws   → test FAILS with detail "<err>"; Cleanup runs
+      - Cleanup throws  → warning printed; test outcome unchanged

+function Test-Case {
+    <#
+    .SYNOPSIS
+    Light alternative to Invoke-AAATest: runs a SINGLE scriptblock as one test
+    case. No $Context threading, no separate Arrange/Act/Assert parameters —
+    the body is plain sequential code, conventionally marked with
+    `# Arrange` / `# Act` / `# Assert` comments. Cleanup is the caller's
+    responsibility via inline `try { … } finally { … }`.
+
+    Use this when the AAA structure adds more noise than value (small tests,
+    tests with simple linear flow). For complex tests where the four phases
+    each have non-trivial setup, prefer Invoke-AAATest.
+
+    .DESCRIPTION
+    Honors the same Set-AAAFilter -Only/-Skip filters as Invoke-AAATest, logs
+    via the same New-TestStep harness, captures exceptions and times the
+    body. Throw from anywhere in the body to fail the test; return
+    normally to pass.
+
+    .PARAMETER Id
+    Stable identifier (used for filtering and the report).
+    .PARAMETER Name
+    Human-readable description (printed and stored in the report).
+    .PARAMETER Body
+    The scriptblock to run. No parameters. Throw to fail.
+    .PARAMETER Tag

+function Reset-AppToHome {
+    <#
+    .SYNOPSIS
+    Forces a target window back to its "home" state by bringing it to the
+    foreground and pressing Escape several times. Useful when a previous
+    test navigated into a sub-page / dialog / mode and you need a clean
+    starting point. Does NOT signal app-specific events (e.g. CmdPal.Show);
+    callers can chain that themselves.
+
+    .PARAMETER Hwnd
+    Window handle to reset.
+    .PARAMETER EscapeCount
+    Number of times to press Escape. Default 5 — handles deeply-nested pages.
+    .PARAMETER ActivateFirst
+    Bring the window to foreground before sending keys. Default $true.
+    Required for SendInput-style key events to land on this window.
+    .PARAMETER PauseMs
+    Milliseconds to sleep between Escape presses. Default 200.
+
+    .NOTES
+    SAFETY GUARD: keystrokes are ONLY sent if the target window is actually
+    the foreground window when each key fires. Win11 sometimes blocks
+    foreground steal — without this guard, our Esc keys would land on
+    whatever IS in the foreground (e.g. the calling terminal), which can
+    cancel running scripts. Verify foreground every iteration; skip the
+    Esc if mismatched.

+# Assertions.ps1 — uniform assertion vocabulary for module checklists (shared across modules/*)

+# Replaces hand-rolled `if (...) { throw "..." }` sites in the CmdPal
+# test suite with a small set of Assert-* verbs that:
+#   - Put the assertion intent FIRST (Assert-Equal vs `if (-ne)`)
+#   - Format failure messages uniformly ("Expected X, got Y — because Z")
+#   - Truncate large values (multi-KB JSON dumps don't flood CI logs)
+#   - Always include the caller's optional -Because reason
+#   - Accept -Because as either a [string] (eager) OR a [scriptblock]
+#     that is only invoked on failure (R2-2 — for expensive diagnostic
+#     context like a UIA probe that should only fire when we're about
+#     to throw anyway).
+#
+# Use inside Test-Case bodies — they throw on failure which New-TestStep
+# catches and records as a test failure (same path as direct `throw`).

+#   $errs = [System.Collections.Generic.List[string]]::new()
+#   if (-not $cond1) { $errs.Add('condition 1 failed: <context>') }

+#
+# When a single condition is checked, prefer the verb-first form:
+#   Assert-NotNull $x -Because 'x must be present'
+#   Assert-Equal $a $b -Because '...'
+#
+# When the failure message needs expensive context (e.g. a UIA probe),
+# pass -Because as a scriptblock — it only runs on failure:

+# Box L1024 — Calculator (5 tests: 3 invocation paths + 2 history)
+# ════════════════════════════════════════════════════════════════════
+# CmdPal exposes Calculator in three user-reachable ways. Each is
+# covered by one full end-to-end test (type expression → invoke Copy →
+# verify clipboard). No separate "result returned" smoke test — the
+# e2e variant already requires the result to be present (you can't
+# Copy something that's not there), so it's a strict superset.
+#
+# We use a DIFFERENT math expression per path so failure messages
+# pin down which path broke without ambiguity:
+#
+#   1. ALIAS path      — '=' alias → Calc sub-page → '5+7'    → '12'
+#   2. EXPLORE path    — 'calc' → invoke Calculator → '17*23' → '391'
+#   3. FALLBACK path   — '999*888' typed on home page         → '887112'
+#
+# Plus 2 history tests (persistent calc history is a separate 0.99.0
+# feature, but kept contiguous here so all Calc coverage is together):
+#
+#   4. History file persists in AppX LocalState
+#   5. History survives AppX re-summon
+
+# ── Bucket fixture: ensure Calculator provider is enabled ──────────
+# All 5 calc tests below depend on com.microsoft.cmdpal.builtin.calculator
+# being enabled. A user (or a sister test) may have disabled it, in which
+# case the '=' alias resolves to nothing and the home-fallback math goes
+# silent. Use-CmdPalProviderEnabled snapshots the current state, enables
+# the provider (restarting the AppX so changes take effect), runs the
+# body, and on exit restores the original IsEnabled value (true / false
+# / missing-entry). Only triggers when at least one calc test will
+# actually run under the current -Only/-Skip filter, so filtered runs
+# never mutate user state unnecessarily.

+# ── Box L1028: Run Commands shell provider via 'run' query ──────────
+# CmdPal 0.99.99 (0.11.11411) regression: the '>' alias no longer navigates
+# when typed via set-value (verified 2026-05-23 — all 7 other aliases work,
+# only '>' is broken: typing '>' leaves it as a literal char in the box).
+# The sibling test CmdPal_Shell_RunCommandActuallyExecutes currently passes
+# by accident because typing 'notepad' on home produces an identical
+# "Run command" fallback row that, when invoked, spawns notepad.exe.
+#
+# This test was updated to drive the Shell provider via the new PR #48033
+# pattern: type 'run' on home to surface the com.microsoft.cmdpal.run
+# tile, then invoke PrimaryCommandButton (which is then labelled
+# 'Run commands') to navigate to the Shell sub-page. Verify the sub-page
+# placeholder is the Shell-specific one. This is strictly stronger than
+# the old alias check because it confirms both (a) the Run commands tile
+# carries its stable AutomationId and (b) invoking the tile actually
+# navigates to the Shell provider sub-page (not a fallback).

+# RUNTIME-VARIANCE NOTE (2026-05-27, R2 follow-up):
+# This test's wall-time varies wildly (observed 14s — 124s) based on
+# CmdPal AppX state at the time it runs. Reason: the for-loop below
+# fires 50 set-value UIA calls in tight succession with NO inter-call
+# sleep (intentional — it IS the rapid-typing stress). Each UIA call
+# round-trips through the AppX UI thread, which takes:
+#   - ~200ms on a freshly-launched, idle AppX (best case, e.g.
+#     immediately after restart with no prior tests run)
+#   - ~2.4s on a state-loaded AppX (typical when this test runs late
+#     in the suite, after 60+ prior tests have churned settings)
+# 50 × 200ms = 10s vs 50 × 2.4s = 120s — a 10x spread that's NOT
+# affected by anything in this test file. The commit message of
+# `e09b465aaa` ("CmdPal #7: ... -42% suite time") overstated the
+# wall-time improvement on the back of a single anomalously-fast
+# run (538s, with Stability at 13.6s). The real, sustained suite
+# wall-time on a typical run is ~900-950s. Tests in this file are
+# not a useful benchmark for measuring Wait-Until conversion
+# speedups; use tests that don't hit AppX in a tight loop (e.g.
+# the schema buckets that read settings.json only).
+#
+# Practical implication for future authors: if you're trying to
+# decide whether a wall-time change is real or noise, ignore the
+# Stability_RapidTyping line and look at the SUM of all other tests.

+#Requires -Version 7.0
+# 23-ProviderIDs.tests.ps1 — new for the PR #48033 modernization round
+# (2026-05-22). These tests exist specifically to exercise and guard the
+# AutomationProperties.AutomationId bindings PR #48033 added in CmdPal's
+# ListItemSingleRowViewModelTemplate (ExtViews/ListItemsView.xaml).
+#
+# Without these tests, a future XAML refactor could silently drop the
+# `AutomationId="{x:Bind Command.Id, Mode=OneWay}"` binding and no test
+# would notice — the suite would continue to pass because every other
+# test falls back to text-mode `inspect+regex` over ItemsList.
+#
+# Each test asserts a stable property of the new ID scheme:
+#   1. HomeExposesCorePlugInTiles — built-in providers are reachable by
+#      their com.microsoft.cmdpal.* IDs on the empty-query home page.
+#   2. CalculatorTileSurfacesForCalcQuery — typing 'calc' reveals the
+#      Calculator tile, AND its selector is invokable (proves the
+#      ListItemSingleRowViewModelTemplate root Group is reachable).
+#   3. WindowsSettingsTileSurfacesForSettingsQuery — typing 'settings'
+#      reveals the WindowsSettings tile via the same ID pattern.
+#   4. WebSearchFallbackAlwaysPresentForNonEmptyQuery — the
+#      websearch.execute.fallback ID surfaces for any non-empty query
+#      (proves the fallback-command AutomationId binding works).
+#
+# Tagged 'schema' because they're presence/regression checks (no mutation,
+# no spawned processes); but they do drive the UI, so total cost is ~2-3s.
+# Dot-sourced from the orchestrator so they share $cpHwnd / other script-scope vars.
+
+# Stable IDs we expect on the empty-query home page. PR #48033 binds these
+# to the provider's Command.Id. If a built-in is disabled per-user the tile
+# may be missing — so we assert a minimum SUBSET rather than the exact set,
+# and require the canonical built-ins that are enabled-by-default.
+#

+# 24-SettingsUI-bindings.ps1 — dot-sourced PARTIAL of 24-SettingsUI.tests.ps1.
+#
+# NOT a standalone test file (no `.tests.ps1` extension). It's dot-sourced
+# from 24-SettingsUI.tests.ps1 and shares its script scope, which means
+# it sees the orchestrator-initialised fixture variables: $cpHwnd,
+# $cpSettings, $cpEnabled, $cpDataDir, $cpsHwnd, $_settingsUITestIds,
+# $script:_settingsUIBucketBackup. Loading it directly (without the
+# orchestrator) would error out on undefined variables.
+#
+# Purpose: UI -> JSON binding tests. Each test clicks one control in
+# the CmdPal AppX Settings window and asserts the corresponding key
+# in settings.json updates. 13 tests covering all toggle + ComboBox
+# write paths across General / Personalization / Dock sub-pages.

+#     "original" snapshot
+#   - Ctrl+C / suite crash (covered by the PS engine event handler)
+#
+# We use Backup-CmdPalSettingsJson + Restore-CmdPalSettingsJson — the

+#Requires -Version 7.0
+# 24-SettingsUI.tests.ps1 — new for the Settings-UI-binding category
+# (2026-05-25). These tests drive the CmdPal AppX's own "Command Palette
+# Settings" WinUI 3 window — toggling a control and asserting the
+# corresponding key in settings.json updates.
+#
+# Catches a CLASS OF BUGS not currently covered by any other test:
+#   - Broken click handler in Settings UI (click does nothing, no save)
+#   - Wrong AutomationId / XAML binding (UI looks right but writes wrong key)
+#   - Type mismatch between UI control and SettingsModel field
+#   - Save semantics regression (toggle no longer persists)
+#
+# Pattern (all tests in this file):
+#   1. Capture original JSON value
+#   2. Open CmdPal AppX Settings window + navigate to target sub-page
+#   3. Toggle the control via Set-CmdPalAppXSettingsControl helper
+#   4. Helper waits for settings.json to actually update on disk
+#   5. Assert new JSON value matches expected
+#   6. Cleanup: restore original value (always, in finally)
+#
+# Cost: ~6s per test (4-5 controls = ~30s total at SlowFactor=1).
+# Tag: 'mutation' (these mutate user settings; safe-restore in finally).
+#
+# Dependencies:
+#   - PR #48033 stable AutomationIds (verified present on 0.11.11411.0)
+#   - $settings (PT Settings hwnd) set by orchestrator
+#   - $cpSettings, $cpHwnd, $cpEnabled set by orchestrator
+
+# Bucket fixture: open the AppX Settings window ONCE, share across tests.
+# Each test navigates to its own sub-page (cheap, ~1s) and restores original
+# value on cleanup. If no Settings-UI test will run under the active filter,
+# skip the (potentially slow ~10s) AppX Settings window open.

+#   SPLIT (review item #6, 2026-05-27): the 718-line monolith was
+#   carved into 3 topical sub-files at this same directory level,
+#   dot-sourced here in the order the original file executed them.
+#   Each sub-file shares script scope so $cpHwnd / $cpsHwnd /
+#   $_settingsUITestIds / $script:_settingsUIBucketBackup are all
+#   visible across the split.
+#
+#   The sub-files use the `.ps1` extension (NOT `.tests.ps1`) to
+#   signal that they're DOT-SOURCED PARTIALS of this orchestrator,
+#   not first-class test files (they would not work standalone — they
+#   reference $cpsHwndB and other fixture variables initialized
+#   above). Naming convention: any `.ps1` file under cmdpal/ that
+#   contains `Test-Case` calls is a partial dot-sourced from a
+#   sibling `.tests.ps1` orchestrator.
+#
+#   What each sub-file holds:
+#     * 24-SettingsUI-bindings.ps1
+#         13 single-line tests: click a control in Settings UI -> verify
+#         settings.json updates. Fast (~8-21s/test); does NOT require
+#         PowerDock to be visible. Covers all toggle/ComboBox write paths.
+#     * 24-SettingsUI-e2e.ps1
+#         7 full E2E tests: click control -> JSON updates -> CmdPal AppX
+#         actually renders the change. Slow (~16-24s/test). Drives
+#         PowerDock window appearance/position/contents (Dock-only).
+#     * 24-SettingsUI-cleanup.ps1
+#         1 bucket safety-net test: verify settings.json is byte-
+#         identical to pre-test snapshot; restore from snapshot if not.
+#         Always runs last.

+# CmdPal providers (Calculator, Files, etc.) live in settings.json under
+# ProviderSettings.<id>.IsEnabled. If a user has disabled a provider, the
+# tests that rely on it would silently fail with confusing messages like
+# "alias '=' did not navigate". A bucket-level fixture (xUnit
+# [ClassInitialize] equivalent) ensures the provider is RESPONSIVE in
+# the live AppX before the test bucket runs and restores any disk
+# mutation on teardown.
+#
+# IMPORTANT: disk state (settings.json on disk) and live state (the
+# running AppX's cached IsEnabled) can diverge — CmdPal AppX caches
+# IsEnabled at startup, so writing settings.json without restarting the
+# AppX leaves them out of sync. The fixture therefore probes the LIVE
+# AppX (not disk) as the source of truth for "is this provider working
+# right now?", and only mutates disk when the probe says the provider
+# is unresponsive.

+# is reachable via the "Settings" button on the CmdPal home page (or
+# from PT Settings → Command Palette → Settings button, or via the
+# tray icon menu).
+#
+# The AppX Settings window exposes 3 main sub-pages:
+#   - General             (NavItem 'GeneralPageNavItem')
+#   - Personalization     (NavItem 'AppearancePageNavItem')
+#   - Dock (Preview)      (NavItem 'DockSettingsPageNavItem')

+# CmdPal — Tests planned but not yet implemented (v0.96–0.99 gap)
+
+This document tracks tests **intentionally deferred** when adding CmdPal coverage
+for the v0.96 → v0.99.1 feature window. The active tests live in
+`command-palette-checklist.ps1`; the entries below explain what would still be
+worth adding, with an honest assessment of cost and value.
+
+The deferral categories follow the project convention:
+
+| Category | Meaning |
+|---|---|
+| `PER-EXT-FILE` | Per-extension settings file is lazily created; only exists after the user opens that extension's settings page. Test would either spuriously skip or require driving the Extensions Settings UI first. |
+| `UI-DRIVING` | Needs `winapp ui invoke` / `winapp ui click` against a sub-page, popup, or context menu. Doable but each new pattern is 30 min – 2 h of UIA probing. |
+| `NEEDS-FIXTURE` | Requires authoring a custom extension binary that emits a specific content type or behavior. Hard to do without adding the fixture to the repo. |
+
+---
+
+## Per-extension settings (PER-EXT-FILE)
+
+PR #46685 (Gave each built-in extension its own settings file with transparent
+one-time migration from the legacy shared settings.json) split per-extension
+prefs out of the shared `settings.json`. Empirical finding: those per-extension
+files **don't exist until the user has opened that extension's settings page**
+(or set a non-default value via the UI). On a fresh CmdPal install, none of
+them are present.
+
+That makes the following tests environment-dependent — they would all silently
+skip on a clean machine and only run after the user has manually touched each
+extension's settings page once. Not worth shipping until that bootstrap is
+automated.
+
+### `CmdPal_WebSearch_CustomSearchEngineSettingRoundTrips`
+- **Tracks**: 0.97.0 — WebSearch extension custom search engine setting.
+- **Why deferred**: The CustomSearchEngine URL is stored in the WebSearch per-
+  extension settings file, not in the shared `ProviderSettings.com.microsoft.cmdpal.builtin.websearch`
+  (which only contains `IsEnabled`/`FallbackCommands`/`PinnedCommandIds`).
+- **To unblock**: drive the Extensions Settings UI page once to force the
+  per-ext file to materialize, then write+restart+verify.
+
+### `CmdPal_PerformanceMonitor_NetworkSpeedUnitSettingRoundTrips`
+- **Tracks**: 0.99.0 PR #46320 — Performance Monitor extension NetworkSpeedUnit choice setting.
+- **Why deferred**: Same PER-EXT-FILE issue. The NetworkSpeedUnit enum
+  (`bits/s` / `decimal bytes/s` / `IEC binary bytes/s`) lives in the
+  PerformanceMonitor per-extension settings file.
+- **To unblock**: same approach as WebSearch.
+
+### `CmdPal_WindowWalker_KeepOpenAfterClosingWindowSettingRoundTrips`
+- **Tracks**: 0.99.0 PR #45721 — Window Walker "Keep open after closing window" setting.
+- **Why deferred**: Same PER-EXT-FILE issue.
+
+---
+
+## Tests that need actual UI driving (UI-DRIVING)
+
+These need a real `winapp ui invoke` / `click` against a sub-page or popup
+that the existing port hasn't probed yet. **Round 3 update:** the "More
+context menu" mechanism IS reachable via UIA in 0.99 (`MoreContextMenuButton`
+→ `PopupHost` window with `CommandsDropdown` List of menu items), so two
+of the previously-deferred entries were promoted to active.
+
+### ~~`CmdPal_PinToDockDialog_HasTitleSubtitleToggles`~~ → **NOW ACTIVE**
+Implemented as `CmdPal_Pin_PinToDockDialogAppearsAfterMoreMenuClick`
+(round 3). The test enables Dock in settings, opens the More menu, and
+verifies the "Pin to dock" ListItem appears.
+
+### ~~`CmdPal_Navigation_PgUpPgDownSkipsSeparatorsAndHeaders`~~ → **NOW ACTIVE**
+Implemented as `CmdPal_Navigation_SeparatorListItemsAreMarkedDisabled`
+(round 3, narrowed scope). Rather than driving PgUp/PgDown via Send-PtKey
+(fiddly across the AppX/UIA boundary), the test verifies the structural
+invariant the fix relies on: separator/header ListItems are marked
+`[disabled]` in the UIA tree, so the navigation logic can skip them.
+
+## Context-menu deferred tests — additional barrier discovered
+
+The list of CmdPal tests that previously cited "CommandsDropdown is UIA-
+virtualised + offscreen" as a blocker is:
+
+  - `CmdPal_Files_ContextMenu_OpenAndCopyPathAndShowInFolder`
+  - `CmdPal_Pin_PinCommandToDockViaContextMenu`
+  - `CmdPal_Registry_NavigateAndCopyKeyPath`
+  - `CmdPal_Calculator_HistoryClearAndDeleteViaUI`
+  - `CmdPal_TerminalProfiles_PinningWithPerProfileIcons`
+
+In 0.99, the menu mechanism IS now UIA-reachable (`MoreContextMenuButton`
+→ `PopupHost` → `CommandsDropdown` List). 2 of these were promoted to
+active in round 3 because they don't depend on which specific item is
+highlighted (PinToDockDialog and separator schema).
+
+But the remaining **4 specific-item context-menu tests** still have a
+deeper blocker discovered in round 4 probing:
+
+**Discovery**: the `MoreContextMenuButton` opens a context menu reflecting
+the CURRENTLY-HIGHLIGHTED list item — NOT the item set via `winapp ui focus`.
+UIA `SetFocus` against a ListItem in WinUI 3 changes accessibility focus
+but does NOT change list-selection highlighting, which is what populates
+the More menu's contents. So tests that need a specific item's context
+menu (e.g. file's "Copy path", registry key's "Copy path", calculator
+result's "Clear history") need to drive REAL keyboard navigation (Down
+arrow) to move the highlight first.
+
+We have `Send-PtKey 'Down'` available, but additional issues:
+
+1. **Window foreground**: `Send-PtKey` requires the CmdPal window to be
+   in the foreground at SendInput time. CmdPal AppX often loses
+   foreground after `winapp ui inspect` or `winapp ui search` calls,
+   so each test needs explicit `Set-WindowForeground` before each
+   keypress.
+
+2. **Popup stability**: the PopupHost window's UIA tree is unstable
+   to repeated `winapp ui inspect` calls — observed cases where the
+   second inspect of the same popup returned empty. Probably the
+   inspect briefly transfers focus, which collapses the popup.
+   Workaround: open the menu, do one inspect, close, repeat for each
+   assertion.
+
+3. **List highlight is non-observable**: there's no `IsSelected=True`
+   on the highlighted ListItem in WinUI 3 — selection state is
+   tracked by the WinUI ListBox's internal `SelectedIndex` which
+   isn't exposed via UIA. So we can't verify "the right item is
+   highlighted before opening the menu" via UIA alone. Tests have to
+   trust that N Down arrows moves N items.
+
+### Estimated effort to unlock the remaining 4
+
+Each test needs:
+- `Set-WindowForeground -Hwnd $cpHwnd` before each Down arrow
+- N x `Send-PtKey 'Down'` (calibrated per test — depends on how the
+  query results are sorted)
+- `winapp ui invoke 'MoreContextMenuButton'`
+- Find popup HWND
+- Single inspect for the desired menu item
+- Invoke that item
+- Verify outcome (clipboard, file deletion, dock band added)
+
+Each test is ~1 h of probing + flakiness mitigation. Total for 4: ~4 h
+of careful work, likely with some tests still ending up flaky.
+
+The most valuable ones to unblock next, in priority order:
+
+1. **`CmdPal_Files_ContextMenu_CopyPathToClipboard`** — clearest signal
+   (clipboard content). Low coupling to other features.
+2. **`CmdPal_Calculator_HistoryClearViaUIDeletesHistoryFile`** — calc
+   history sub-page only has 2-3 commands so highlight management is
+   simpler than Files. Strong outcome (file size goes to ~empty).
+3. **`CmdPal_Pin_ActuallyPinsCommandToDockBand`** — extends round-3 Pin
+   dialog test by actually clicking the dialog's Pin button. Need to
+   probe the dialog's UIA tree (separate Popup or inline?).
+4. **`CmdPal_Registry_DeepWalkAndCopyKeyPath`** — needs registry
+   sub-page deep navigation first; most complex.
+
+### `CmdPal_ClipboardHistory_DragDropCapabilityExposed`
+- **Tracks**: 0.97.0 — ClipboardHistory drag-drop support added in 0.97.
+- **Why deferred**: UIA doesn't directly expose "this element supports
+  drag-drop"; would need a custom IDataObject probe via Win32
+  OleGetClipboard after starting a drag. Not impossible but not 30 min.
+- **Effort**: ~2-3 h.
+
+### `CmdPal_Indexer_WindowsSearchAvailabilityIndicatorShown`
+- **Tracks**: 0.99.0 PR #46907 — Indexer search shows Windows Search availability indicator.
+- **Why deferred**: Round 3 probing was inconclusive — the indicator may
+  only render when Windows Search is actually unavailable (which is
+  rare on dev machines, so test would trivially skip). To test it
+  meaningfully, we'd need to temporarily stop the WSearch service
+  (admin + side-effects on the host).
+- **Effort**: ~2 h + requires admin.
+
+---
+
+## Tests that need an authored extension fixture (NEEDS-FIXTURE)
+
+### `CmdPal_Extensions_PlainTextContentTypeRendersInDetailsPanel`
+- **Tracks**: 0.99.0 PR #43964 — plain text viewer IContent added to extension SDK.
+- **Why deferred**: There is no built-in extension that emits plain text
+  content. We'd need to author and install a tiny test extension whose
+  command exposes a plain-text content panel, then query for it.
+
+### `CmdPal_Extensions_ImageContentTypeRendersZoomableImage`
+- **Tracks**: 0.99.0 PR #43964 — image viewer IContent added to extension SDK.
+- **Why deferred**: Same as plain text — no built-in extension produces an
+  image-typed content panel.
+
+### `CmdPal_Extensions_BadExtensionDoesNotBreakOthers`
+- **Tracks**: 0.99.0 PR #47032 — one bad extension no longer kills the loop.
+- **Why deferred**: Already documented in the .ps1 skip list as `NEEDS-FIXTURE`.
+  Same root cause — need a deliberately-broken extension binary.
+
+---
+
+## Implemented in this round
+
+For reference, the **13 active tests** added to track 0.96 → 0.99 features
+(13 = 9 from round 1 + 4 from round 2):
+
+**Round 1 (commit `546c0f1030`)**:
+- `CmdPal_DockSchema_NullDockSettingsDoesNotCrashOnStartup` (★ 0.99.1 PR #47296)
+- `CmdPal_DockSchema_ShowLabelsPersistsAcrossSessions` (★ 0.99.1 PR #47317)
+- `CmdPal_DockSchema_BandsHavePerCommandShowTitleAndSubtitleFields` (★ 0.99.0 PR #46436)
+- `CmdPal_DockSchema_BackdropFieldHasValidValue` (★ 0.99.0)
+- `CmdPal_DockSchema_DockSizeFieldIsKnownEnum` (★ 0.99.0 PR #46699)
+- `CmdPal_State_LocalStateFilesPresentAndValid` (★ 0.99.0 PR #46685)
+- `CmdPal_Settings_PersonalizationFieldsExistInSchema` (★ 0.97.0)
+- `CmdPal_Providers_NewBuiltinProvidersFor097And099Present` (★ 0.97-0.99 PR #46198)
+- `CmdPal_Stability_TypingDoesNotCrashWithProviderSettingsIntact` (★ 0.99.0 PRs #47148+#47186)
+
+**Round 2 (this round)**:
+- `CmdPal_Settings_FallbackRanksFieldIsValidArray` (★ 0.97.0)
+- `CmdPal_PowerToysExtension_FancyZonesLayoutsListedViaSearch` (★ 0.97-0.99 PR #46198)
+- `CmdPal_PowerToysExtension_ColorPickerListedViaSearch` (★ 0.97.0)
+- `CmdPal_TerminalProfiles_BadGuidInWtSettingsDoesNotBreakListing` (★ 0.99.0 PR #46372)
+
+---
+
+**Round 3 (this round)** — implemented 2 of 5 UI-driving deferrals after probing:
+- `CmdPal_Pin_PinToDockDialogAppearsAfterMoreMenuClick` (★ 0.99.0 PR #46436)
+- `CmdPal_Navigation_SeparatorListItemsAreMarkedDisabled` (★ 0.99.0 PR #46439, narrowed scope)
+
+Empirical finding (round 3): the `MoreContextMenuButton` IS UIA-reachable
+in 0.99 (was previously assumed virtualised+offscreen). Clicking it
+opens a separate `PopupHost` window containing a `CommandsDropdown`
+List with addressable menu items. This unblocks the entire family of
+"context menu → invoke item" tests for free; the remaining ones are
+deferred only because their downstream UI (dialogs, dock window) needs
+more probing.

+# This section was missing from earlier batches. CmdPal's UIA tree is
+# available even when the window is hidden (the AppX hosts a foreground-aware
+# UIA provider; the tree is queryable in either state).
+#
+# Pattern:
+#   1. Signal CmdPal.Show event (re-summon if auto-dismissed)
+#   2. winapp ui set-value 'MainSearchBox' <query>
+#   3. winapp ui search <expected-result-text> -- assert matchCount > 0
+#
+# These are TRUE FUNCTIONAL tests — the calculator must compute correctly,
+# the file search must return files, etc. — not just schema.
+#
+# AutoGoHomeInterval can be aggressive (-00:00:00.0010000 = 1ms by default
+# in some builds) so we re-signal Show before each query.
+
+# Acquire the CmdPal window. When CmdPal is enabled + AppX is installed we
+# proactively summon it (signal CmdPal.Show + poll for the visible window) —
+# the prior one-shot `list-windows` read returned null whenever CmdPal had
+# auto-dismissed on focus loss, which silently auto-skipped 50+ functional
+# tests and masked real failures. If the AppX is genuinely uninstalled or
+# CmdPal is disabled in PT, $cpHwnd stays null and the legacy SKIP stubs at
+# the bottom of the script take over (preserves the "CmdPal not present"
+# behaviour for environments where the suite is run without CmdPal).
