# Checks auth-file.lua and auth-inline.lua, the shipped auth filters, which
# share their cookie signing, redirect vetting and action flows and differ
# only in where accounts live. The unit checks under a standalone Lua meet
# luaossl and luaposix with deterministic stand-ins from the harness, so
# they prove this script's own logic on any machine, tampered and expired
# cookies turned away, header injection stripped, unsafe redirects refused
# and the login flows answering as documented. The run through cgit itself
# needs the real modules inside the binary's own Lua, so it is probed for,
# and an unedited copy protects nothing, which is itself the behaviour worth
# proving end to end.
