Four-Phase Cache TTL Timeline

Description

Five-phase cache TTL timeline derived from Tsai's 95-day scan: Phase 1 (Jan 9 – Feb 5, 28 days): 100% 5m sub-agent, no main-agent data — 1h not yet rolled out. Phase 2 (Feb 6): 79% 1h transition day. Phase 3 (Feb 7 – Mar 5, 28 days): '100% 1h golden era' both tiers. Phase 4 (Mar 6 – Apr 8): sub-agent 1h-5m mixed (6-97%), main agent still 100% 1h — first silent regression. Phase 5 (Apr 9 – present): sub-agent 100% 5m (5+ days, 4,840 calls with 0 × 1h), main agent still 100% 1h — second silent regression.
