Workflow now targets Simone/nsis-plugin-ns7zip. Renamed the file and the workflow `name:`, and updated all references in active docs (plans/archived and docs/archived left as frozen history).
Master checklist + step A5 attivita + 'definizione di fatto' updated; A5-closeout.md added (116 pytest, coverage 80.10% total, gate raised to 80%). Hardware validation (burn-in 4x10 + workflow matrix end-to-end) deferred to user. Shim PS removal deferred to B5 (systemd timers): all 10 shims still referenced by Register-CIScheduledTasks.ps1 / docs / Test-*.ps1.
