A barrel's 'module NAME' makes its directory a module; a declaration other modules use says 'export'. Private use from another module is an error naming the module and where to mark it; 'friend module' sees everything (a test harness); a file in no module is public and a package keeps its own module. LUDIC_VIS_REPORT=1 lists every violation instead of stopping, so a codebase can be given its exports first. Co-Authored-By: Claude Opus 5.5 <noreply@anthropic.com>

# visible.ludic — L3: a program in no module uses what module bank exports: a function to call

# and an event to listen to. Its private `add` and `balance` stay out of reach.

# Running it prints: 42 42
