SignalDedup: 24h-rolling duplicate signal blocker. SQLite WAL + busy_timeout=120000 standard fix (reference_sqlite_concurrency.md pattern). PK (ticker, action) with UPSERT. Phase 4 (signal generator) will call is_recent() before sending + record() after sending. 3 unit tests pass, total 17 signal_v2. Co-Authored-By: Claude Opus 4.7 (1M context) <noreply@anthropic.com>
