Mira formulated a pragmatic path: keep the obfuscation layer for telemetry destined for external analytics, but bypass it for local diagnostics; introduce a “whiteboard” channel that carried persistent, minimal device identifiers only to on-site controllers; and patch the rolling salt mechanism to include a grace window and backward-compatibility mapping so that continuity survived rotation. She also wrote a fail-open health check: if the obfuscation gate failed, it would default to transparent telemetry with strict local retention policies. The laptop fan roared
