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>

**Modules.** `module NAME` in a barrel makes its directory a module, and a module's
|
|
declarations are private to it unless they say `export`: a function, global, record or event of
|
|
another module used without one is an error naming the module and where to mark it. `friend
|
|
module NAME` 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 an existing
|
|
program can be given its exports by a script before the rule applies to it.
