- localSink.ts: writes every logEvent to ~/.claude/local_analytics.jsonl
- Modified index.ts: logEvent() now writes locally in parallel with upstream sinks
- analyze_analytics.py: Python analysis script — event stats, tool rankings,
time distribution, security events, RL preference signals
No upstream data flow is affected. Local writes are non-blocking append.
Testing: one -p 'hello' captured 32 events across 19 event types.
