Tradier stack emitted account/positions/orders events hardcoded as broker_name=alpaca_paper while the executor filters snapshots by client.broker_name (tradier) — position cap and re-entry block read zero positions, and the dashboard showed 'Alpaca Paper' over real Tradier values. Mode label now defaults from BROKER/TRADIER_ENV (tradier_live) instead of alpaca_paper. Co-Authored-By: Claude Fable 5 <noreply@anthropic.com>
