Parallel ledger writers no longer silently lose windows entries — two concurrent gsd_run windows append (or waive/fixed) invocations both reported success while one entry vanished from WINDOWS.md, false-greening the /gsd-ship gate; the mutating commands now serialize on a cross-process ledger lock and refuse with a typed windows_ledger_lock error only when a live writer holds it past the retry budget.
