W kontrolowanym wariancie pomiń \texttt{portYIELD\_FROM\_ISR}, zachowując GiveFromISR. Zmierz, kiedy waiter zacznie działać i wskaż następny legalny scheduling point.
\par\textbf{Evidence:} Dwa timestampowane ślady E07/E08 z yield i bez yield oraz opis różnicy.
\par\textbf{Acceptance:} Uczeń nie myli odblokowania taska z natychmiastowym wykonaniem i przywraca poprawny yield w wersji finalnej.
\end{ESCBlockFrame}
\tcblower\textbf{Task acceptance:} PASS; mcause=MEI; source=0 przed give; xHPW=1; waiter E07 przed stimulus E08; trzy różne stosy; deterministyczny digest.
\end{ESCTaskFrame}
\begin{ESCConclusionFrame}
ISR działa na osobnym stacku i używa FromISR API. \texttt{xHigherPriorityTaskWoken} jest informacją dla portu; dopiero \texttt{portYIELD\_FROM\_ISR} powoduje restore kontekstu wyższego taska przed powrotem do przerwanego kodu.
