# Step 1: Install
uv pip install vulture

# Step 2: Scan with 80% confidence threshold
vulture src/ --min-confidence 80

vulture src/ vulture_whitelist.py --min-confidence 80

# Step 1: Install (project-local recommended)
bun add -d knip

# Step 2: Initialize config
bunx knip --init

# Step 3: Scan for dead code
bunx knip

# Step 4: Auto-fix (removes unused exports)
bunx knip --fix

# Step 1: Scan for dead code warnings
cargo clippy -- -W dead_code -W unused_imports -W unused_variables

# Step 2: For stricter enforcement
cargo clippy -- -D dead_code  # Deny (error) instead of warn

# Step 3: Auto-fix what's possible
cargo clippy --fix --allow-dirty

Search for references to [IDENTIFIER] in:
1. TODO/FIXME/HACK comments in codebase
2. Issue tracker (open and closed issues)
3. Design documents and architecture decision records
4. README and project documentation files
Report: Was this code planned but not yet integrated?

For [IDENTIFIER], analyze:
1. All module import/include/use statements
2. Runtime module loading mechanisms (lazy loading, plugins)
3. Framework-invoked patterns (metadata attributes, config bindings, annotations)
4. Test files that may exercise this code path
Report: Is there a partial or indirect call chain?

For [IDENTIFIER], check:
1. VCS blame/annotate - who wrote it and when
2. Commit message - what was the stated intent
3. Code review / merge request context - was it part of larger feature
4. Recent commits - was calling code removed or refactored
Report: Was this intentionally orphaned or accidentally broken?

# Step 2: For each high-confidence finding, spawn validation
