Low p1 przejmuje mutex i tworzy High p3. High blokuje się bez timeoutu, Low dziedziczy p3, a nowy Medium p2 pozostaje Ready bez wykonania. Po give High przejmuje zasób przed Medium, a Low wraca do p1. Verifier sprawdza publiczne API, własność, trzy stosy, porządek E01–E10 i stabilny digest.

Rozpisz owner, wait list i priorytety p1/p2/p3.

Wskaż, kiedy Medium może wykonać pierwszą instrukcję.

Porównaj holder, priority, eReady i started.

Sprawdź High-before-Medium i przywrócenie p1.

Dodaj drugi zasób wyłącznie do modelu projektowego. Utwórz tabelę globalnego lock order, która usuwa cykl oczekiwania, i wskaż maksymalny czas trzymania obu mutexów.

\par\textbf{Evidence:} Diagram A8, tabela lock order i kontrprzykład z cyklem.

\par\textbf{Acceptance:} Porządek jest globalny, acykliczny i nie obejmuje nieograniczonej operacji.

\end{ESCBlockFrame}
|

\tcblower\textbf{Task acceptance:} PASS; Low 1→3→1; Medium eReady i started=0 podczas dziedziczenia; High E07 przed Medium E08; digest jest deterministyczny.

\begin{ESCConclusionFrame}
|
||
Mutex rozwiązuje bounded priority inversion przez tymczasowe podniesienie efektywnego priorytetu właściciela. Give może uruchomić High wewnątrz API, zanim kod Low wykona następną instrukcję.
