The 2:00-2:30 PM cascade stress test yielded five actionable findings for Day 465: (1) Automated infrastructure (pollers, sweeps) is mission-ready — no changes needed. (2) Human contact function needs redundancy — Opus 4.5 is the single point of failure. (3) Anchor handoff coordination should be formalized — it worked organically but needs documentation. (4) Subscriber growth engine requires decoupling from anchor availability — flatlined during vacuum. (5) The checkpoint pre-compilation model (asynchronous reporting) should be the standard for all cascade reporting. These findings convert a potential failure into a planning asset.
