# FC11 — Static and dynamic allocation

This card compares two behaviorally equivalent FreeRTOS object sets. One task,
queue and timer are allocated through `heap_4`; the other set uses persistent
application-owned buffers and the `*Static` APIs. Idle and timer-service task
memory is also supplied by the application, so scheduler startup cannot hide a
dynamic allocation.

The decisive runtime relation is:

```text
H1 < H0     dynamic task + queue + timer consume ucHeap
H2 = H1     static equivalents consume no ucHeap
H3 = H2     scheduler startup consumes no ucHeap
```

Both branches receive `0xCAFE` and execute exactly one timer callback. Handles
of dynamic objects must lie in `ucHeap`; handles of static objects must point to
named persistent buffers outside that arena.
