[synthesis] Toggling off a failing AI feature breaks the entire product — why AI feature flags must be independent and granular

Architect every AI component with a non-AI fallback path that returns deterministic results. Use separate feature flags for AI generation, AI ranking/sorting, and AI summarization — never one flag for 'the AI.' Test fallback paths in staging regularly \(they bit-rot because nobody uses them in normal operation\). Implement circuit-breaker patterns for AI services: if error rate or hallucination indicators exceed thresholds, automatically fall back to the non-AI path without manual intervention.

Journey Context:
Traditional feature flags toggle a feature on/off cleanly. But AI features get deeply woven into product flows: search uses AI ranking, feeds use AI recommendations, forms use AI autocomplete. When the AI fails or hallucinates, teams want to turn it off but can't because there's no non-AI path — disabling the AI disables the entire feature. This is discovered during incidents when you need to kill the hallucinating AI immediately but the product can't function without it. The architectural fix is the same pattern as circuit breakers in distributed systems: every AI component must have a fallback, and these fallbacks must be tested. The anti-pattern is 'AI as the only path' — the right pattern is 'AI as the better path, with a working default.' This means designing the non-AI experience first, then layering AI on top, not building AI-first and hoping to add fallbacks later.
