+Operating-system contracts are likewise explicit. Run `Lane=Windows` on a
+Windows host and `Lane=Linux` on a native Linux host; a lane is not portable
+evidence when executed on the other operating system.

+`Lane=SystemFont` exercises the BitmapFont path against a host-provided TTF.
+It is separate because the supported runtime can legitimately have none of the

+## Batch D prerequisite lanes and Avalonia ownership
+
+The reviewed prerequisite map classifies every true candidate without deleting
+its existing guard:
+
+| Lane | Attributed methods | Prerequisite |
+|---|---:|---|
+| `InstalledDat` | 336 | Installed retail DAT directory; includes the 73 custom installed-DAT facts and whole DAT-backed investigation classes. |
+| `PreparedPackage` | 2 | Installed DATs plus validated `acdream.pak`. |
+| `Live` | 3 | Explicit live handshake opt-in and reachable service. |
+| `Manual` | 1 | Explicit fixture-regeneration opt-in. |
+| `Windows` | 7 | Windows-only filesystem/process/timer behavior. |
+| `Linux` | 10 | Linux permission/signal/monotonic-clock behavior. |
+| `SystemFont` | 2 | A host system TTF available to the BitmapFont path. |
+
+Class-level traits legitimately cover some additional methods that share the
+same fixture owner, so the 336 installed-DAT method count is larger than the
+280 syntax candidates. The only candidate methods without a lane are
+`GraphicalHostPlatformServicesTests.CurrentPlatformOwnsPathsPacingAndNativeClosure`
+and
+`LinuxMonotonicFramePacingWaiterTests.PlatformFactorySelectsCurrentOperatingSystem`.
+Both are hermetic cross-platform branch tests: on Windows or Linux they assert
+the matching branch and return only after the assertion. They are not silent
+prerequisite passes.
+
+The 11 conditional `SkipException.ForSkip` source sites are also reconciled.
+They serve 12 test methods: installed-DAT asset contracts, one prepared-package
+contract, and two system-font contracts. xUnit v2 reports that exception shape
+as a failure rather than a dynamic skip, but the owning lanes now keep them out
+of the hermetic total. A later body-cleanup batch will replace the misleading
+skip wording/exception with explicit prerequisite failure or discovery-time
+lane behavior.
+
+The first complete Batch D gate correctly failed in Launcher cleanup after
+14,396 passes: the six `MainWindowViewTests` Avalonia facts could start and
+destroy isolated thread-affine compositors on different xUnit workers. The
+assertion bodies were preserved as six named private phases under one
+`CompiledMarkupAndEveryModalFocusPathRunInOneOwnedAvaloniaSession` fact. The
+focused two-case class then passed in 25 consecutive fresh processes (50/50
+results), and the same full-gate context passed.
+
+Batch D verification:
+
+- complete 44-project Release build: 0 warnings, 0 errors;
+- final syntax manifest: 11,450 attributed methods, 51 diagnostics, one known
+  failure, 282 prerequisite-return candidates, and only the two reviewed
+  cross-platform false positives unlaned;
+- complete hermetic Release gate: 14,392 passed / 0 skipped / 0 failed across
+  all 12 test assemblies in 131.518 seconds; and
+- Launcher view stress: 25 fresh processes, 2/2 cases per process, no cleanup
+  or ownership failures.
+
+The 350-pass reduction from the clean R2 headline is exactly explained: batch A
+netted minus one case; batch B removed six non-hermetic passes; batch C removed
+68 newly classified diagnostic cases; batch D removed 270 prerequisite-lane
+passes; and consolidating the six Avalonia sessions into one removed five case
+IDs without removing any assertion phase. All 77 former default skips are also
+accounted for by the PVS deletion and batch-B lane/deletion decisions.
