Seven independent readers each forked powershell.exe to run Get-CimInstance Win32_Process, with a wmic fallback that Windows 11 24H2 has removed. On a domain-joined host with PowerShell Transcription enabled by policy, one of them running every ~2s recorded ~289GB across 1.4 million files (#15209). The same scan cost ~700ms and ran per pane (#15036), and a Group Policy or AV block turned it into 'unavailable', which callers read as 'no evidence' -- which is how a PTY tree survives its own teardown (#9045, #10475). A Toolhelp32 snapshot answers the same question with no child process. Measured on Windows 11 with 1050 processes, p50/p95: pid+ppid+name 15.9 / 17.5 ms +memory +command line 30.6 / 33.7 ms Get-CimInstance 706 / 723 ms Two upstream defects needed patching, both found by running it on real hardware. The binding requires Spectre-mitigated libraries our agents do not carry (node-pty is patched the same way). And enumeration stopped after 1024 processes: on a host with 1051 the module returned exactly 1024, and the querying process was itself among the 27 missing -- a truncated snapshot silently hides the descendants teardown is looking for, which is the failure this whole change exists to remove. Migrated: the foreground/descendant reader (the #15209 scraper and the teardown identity gate) and the port scanner's PID attribution. NOT migrated: the memory collector and three identity probes, which need Win32_Process.CreationDate and have no native equivalent. Start time is a proxy for identity anyway; an inherited job handle is the real answer, so those belong with the job-object work rather than here. Packaging follows the windows-native-registry contract exactly: optional, absent from onlyBuiltDependencies so macOS/Linux never run node-gyp, win32-only in the packaged runtime. Asserted by the existing contract test, which also stops pinning a whole source literal that only tested its own formatting.
