# FC06 card plan

## Thesis

Software timer APIs enqueue commands. A dedicated FreeRTOS daemon updates timer
lists and invokes callbacks later on its own task stack. Command acceptance is
therefore not callback completion.

## Evidence

- both start commands accepted;
- one-shot reset at tick 1 moves expiry to tick 6;
- auto callbacks at ticks 2 and 4;
- period change to three ticks produces the next callback at tick 7;
- one-shot fires once, auto is stopped, daemon handle and stack differ from the
  controller, and ten committed records produce a stable digest.
