#!/usr/bin/env php
registry: 33 functions (+ unset), reserved words: 15

DRIFT between the DSL source and skills/businessmap-code-runner:

  - crlint.py KNOWN_FUNCTIONS is missing `set_error_card` — it would be reported as an unknown function
  - crlint.py MIN_ARGS is missing `set_error_card` (requires 1)
  - FUNCTIONS.md has no `### set_error_card(...)` entry

3 problem(s). Update the skill in the same commit as the DSL change.
