Owner scope 2026-11-12 (Windows x64 + Linux, unchanged cycle-3 caps, >=7200 s, SDK 1.5 comparator).
- Linux ARM64 (late-slope, 7200.12 s, 1964 cycles / 491 restarts, shutdown verified, analyzer-validated):
first rejection RSS at cycle 247 / 900.73 s, 358,682,624 > 358,678,528 (+4 KiB); peak 382.98 MiB vs
limit 342.06 MiB; late plateau medians 344.4/341.1/341.9 MiB, OLS -1.90 MiB/h. FAIL.
- Windows x64 on windev (same workload, working set as RSS, handle table as descriptors): first rejection RSS
at cycle 285 / 1130.76 s, 303,505,408 > 302,174,208; peak 319.49 vs limit 288.18 MiB; plateau ~314-315 MiB,
+0.93 MiB/h. FAIL. Also incomplete: the launcher's wall-clock outer deadline fired early after a +552 s
w32time step and ended the run at test-phase 7014 s (rejection had already latched); launchers now use a
Stopwatch.
- SDK 1.5.378.182 comparator (efb9197a publication, Windows, 7201 s): RSS peak +65.8 MiB (never over its cap),
plateau ~+48 MiB, but the +32 handle cap tripped at cycle 17 (max 674 vs 642).
- Managed flat on both SDK2 runs; growth is the generated-factory JIT burst (+40k/+44k methods) - Linux JIT
doublemapper ~180 MiB; Windows private bytes grew ~25 MiB of a ~132 MiB working-set rise.
- Retained: b61f3e05 cycle-1 fixture failure (#808 unplaced UNS folder), Windows/SDK1 smoke diagnostics.
No cap raised, no warm baseline, no failed run counted as passing.

Acceptance runs for #799 (owner scope 2026-11-12: Windows x64 + Linux) on current master.
Fixture: since #808 an UNS folder the authority snapshot does not place is denied under enforcement (fail
closed). The canonical soak creates its own "SoakEquipment" folder but never placed it, so on master the very
first cycle's UNS monitored item came back bad (retained failed Linux launch on b61f3e05, cycle 1). The rig
gains AdditionalFolderScopes (merged into FolderScopes by Enforce) and the soak places its folder there, as a
deployed generation does - the same fixture gap #888 fixed for the SDK matrix. No server authorization code,
cap, baseline or canonical operation changed; the soak test bodies are otherwise byte-identical to b18f9723.
Windows port (test/harness only, opt-in):
- DescriptorCountsAsync gains a Windows branch: total = every handle in the process handle table, PKI = disk
file/directory handles whose GetFinalPathNameByHandle path lies under a canonicalised PKI root; dedicated
thread under the same 5 s bound as the macOS lsof probe.
- Descriptor controls enabled on Windows (symlink alias; timeout control via cmd.exe + ping).
- LateSlopeRun.ValidateRequest accepts Linux ARM64 or Windows x64; duration/runtime/leak tracking unchanged.
- late-slope/analyze.py: expected architecture is a module constant (Linux default Arm64 unchanged).
- windows/: prepare.py (win-x64 self-contained 10.0.14 bundle + manifest), launch.ps1 (container.sh
equivalent: bundle re-verification, 2/2 controls first, PID/apphost/coreclr verification, external
sampler, 7440 s outer deadline), analyze.py (Linux row/window logic, X64), README with every adaptation.
