📋 Decision Context

Question:

Create QualityDropTrigger — hourly cron that detects execution success rate regression

Task: Not specified

🎯 Decision Made

Chosen:

Implemented QualityDropTrigger with hourly @Cron job and 3-test suite

Options Considered:

• No alternatives documented

💭 Reasoning

QualityDropTrigger monitors execution_traces for 24h vs 7d success rate regression (>15% drop). Queries MongoDB with time windows, calculates rates, dispatches via ProactiveDispatcherService when threshold exceeded. Tests cover: (1) stable rate—no alert, (2) 30% drop—alert fired, (3) insufficient tasks—early return. All tests passing.
