Windows agent foreground-process inspection forks a whole-process-table PowerShell/CIM scan per pane on the same 750ms/2000ms cadence the POSIX path uses. The POSIX side routes through getProcessTableSnapshot (500ms TTL + single in-flight, #6288/#6667), collapsing N concurrent panes to ~2 scans/sec. The Windows path (queryWindowsProcessDescendants) had no such dedup: K concurrent agent panes forked K powershell.exe cold-starts, each enumerating the ENTIRE process table then filtering per-pid in JS — ~10-40x heavier than `ps` (a powershell cold start is ~150-400ms CPU + tens of MB RSS). The degraded/local PTY provider path calls it with no per-pane throttle at all. This is the Windows analogue of the idle-CPU churn #6288 fixed for POSIX. Generalize the existing createProcessTableSnapshotReader factory to be generic over its scan result (default T = string, so the POSIX path and its test are byte-identical) and add a Windows singleton reader that caches parsed WindowsProcessRow[]. queryWindowsProcessDescendants now reads the shared snapshot and runs its own descendant walk; runWindowsProcessRows throws on total enumeration failure so the miss is not cached and the prior null-fallback contract (callers fall through to node-pty's name) is preserved. Windows scan-volume regression test (mirrors the POSIX #6288 guard) drives PANE_COUNT concurrent panes over the cadence window and asserts powershell.exe spawns are bounded by ticks, not pane count, while every pane still resolves its descendant. Reverting the dedup fails both cases. POSIX snapshot + volume tests unchanged and green; node/web/cli typecheck clean. Co-authored-by: Orca <help@stably.ai>
