.SYNOPSIS
    Testeaza ramura "pe baterie" fara sa scoti UPS-ul din priza: scrie SIMULARE.json,
    urmareste logul, apoi curata dupa el.

.DESCRIPTION
    Se ruleaza PE SERVER, ridicat (Administrator), cu monitorul deja pornit.

    Implicit, oprirea e parcursa IN GOL: se trimit emailurile, se scriu in log toti
    pasii, dar nu se opreste nici Oracle, nici Windows. Asta valideaza tot lantul
    decizie -> alerta -> secventa, adica exact partea pe care o pana reala ar
    exercita-o.

    Ce NU acopera: faptul ca Windows chiar raporteaza trecerea pe baterie. Acela e
    deja dovedit de perechile de evenimente Kernel-Power 105 de la panele reale
    (10 iun, 13 mai, 5 mai 2026) - vezi docs/ups-server36-monitorizare.md.

    Simularea expira singura si e stearsa de monitor; scriptul o sterge oricum la
    final, inclusiv daca e intrerupt.

.PARAMETER Percent
    Incarcarea raportata. Sub pragul shutdownAtBatteryPercent (implicit 35),
    declansarea vine dupa confirmPolls cicluri - adica in ~45 de secunde.

.PARAMETER Minute
    Cat timp ramane activa simularea.

.PARAMETER ConfirmReal
    Repetitia exacta 'DA-OPRESTE-SERVERUL' transforma testul intr-o repetitie
    REALA: Oracle chiar se opreste si Windows chiar se inchide. De folosit doar
    intr-o fereastra de mentenanta anuntata.

.EXAMPLE
    # repetitie in gol - sigura oricand
    powershell -ExecutionPolicy Bypass -File .\test-battery.ps1

.EXAMPLE
    # doar trecerea pe baterie, fara sa se atinga pragul de oprire
    powershell -ExecutionPolicy Bypass -File .\test-battery.ps1 -Percent 80 -Minute 3

.EXAMPLE
    # repetitie REALA, in fereastra de mentenanta: opreste Oracle si serverul
    powershell -ExecutionPolicy Bypass -File .\test-battery.ps1 -ConfirmReal 'DA-OPRESTE-SERVERUL'
