#!/usr/bin/env bash
# Sibling test for b32_utils.sh. Asserts the pure helpers behave
# as documented: profile parsing populates the PROFILE_* arrays,
# the file classifiers split on .test extension correctly, and
# the line counter matches the TS "split('\n').length" semantics.
#
# A minimal in-file harness (no bats dependency): each test calls
# `assert_eq` which prints PASS/FAIL and increments counters.
# Exit 0 if all assertions pass, 1 otherwise. Run from any cwd.
