fpc-msgbase/tests/test_read.pas

{
  test_read.pas - read-only smoke tests against real BBS
  sample bases at /home/ken/fidonet/msg/.  Validates that our
  unified API returns the expected counts and first/last
  records for each format.

  If the sample directory isn't present the tests are skipped
  (returns 0 so CI still passes on fresh checkouts).
