The Architecture Decision That Lets a Live Trading Bot Update Itself

Most systems treat deployment as a pause button. Foresight treats it as a signal. Here's the architecture that lets a 24/7 trading bot absorb code changes without ever stopping.

The 10-Second Death Zone: How a Hardcoded Threshold Was Killing 11 Trades a Day

Our live Polymarket trading bot was scoring 11 high-conviction signals per day (avg score: 83.3) and blocking every single one. The culprit: a 10-second timing threshold we'd never questioned. Here's what production data taught us about hardcoded constants.
