Canary promotions & auto-fallback telemetry
Canaries that win in A/B can now be promoted straight from the route flow. Fallbacks emit their own metrics so you can tell cheap recoveries from quiet degradations.
- Promote canary button on the A/B card · one-click shift of traffic + audit entry.
- Fallback metrics — strataix.fallbacks.fired, .resolved, .added_latency_ms.
- Natural-language ask in ⌘K · explains spikes and suggests fixes.
- Smarter cost delta: cache-hit requests now subtract from the baseline, not add to it.
