/dead-code

Find public functions that nothing calls (excluding tests). Uses RNA's graph to identify candidates — not a compiler, so results are heuristic. False positives exist (framework callbacks, trait impls, FFI exports, CLI dispatch targets).

Arguments

$ARGUMENTS should be: [scope]

• No arguments: scan the whole repo
• File path: src/service.rs — scan one file
• Directory: src/extract/ — scan a subtree
• Subsystem: subsystem:code — scan an RNA-detected subsystem

Examples:

• /dead-code
• /dead-code src/embed.rs
• /dead-code src/graph/
