Findings

Dead Code Detection

High Confidence: 111 candidates
False Positive Rate: 25-33%

Known Regression

Svelte component method references not detected:

<!-- ChatInput.svelte -->
<script>
export function focusInput() {
    richText.richTextEditor?.focus();
}
</script>

<!-- Usage in parent - NOT DETECTED -->
<ChatInput bind:this={chatInput} />
{chatInput?.focusInput()}

Version History

Version	FP Rate	Status
0.5.16	40-50%	Default imports broken
0.5.17	8.4%	Major improvement
0.6.1-dev	0%	PERFECT
0.6.2-dev	25-33%	REGRESSION

Commands Used

cd GitButler
loct                              # Create snapshot
loct dead --confidence high       # Dead code analysis
loct twins                        # Duplicate detection

Verdict

REGRESSION - Svelte component method refs need fixing.

Key Insights

Svelte Components: Method refs via bind:this not tracked
Rust Analysis: Works well
Tauri Integration: Command bridges functional

Workaround

Until fixed, manually verify Svelte component exports:

loct dead --confidence high | grep ".svelte" | while read line; do
    symbol=$(echo "$line" | awk -F: '{print $NF}')
    rg "\\.$symbol\\(" . --type svelte
done
