+# FC07 card plan
+
+## Thesis
+
+An ISR and a task use different APIs and different stacks. A FromISR operation
+may unblock a higher-priority task, but the task runs immediately only if the
+ISR explicitly requests a context switch.
+
+## Evidence
+
+The nine-record replay proves a real MEI cause, source clear before give,
+`xHigherPriorityTaskWoken=pdTRUE`, distinct ISR/waiter/stimulus stack pointers,
+and ordering `ISR → waiter → interrupted stimulus`.
