A review found that an open page kept sending to a DSN after consent was taken back, that a state file or config file could name where telemetry goes, and that `BULWARK_TELEMETRY=off` did nothing on the desktop build. A due heartbeat now waits a random 30 s to 10 min, a refusal from the collector isn't retried, crash files go at sign-out and account switch, and server builds parse stacks as they did. Existing assertions changed in the desktop telemetry tests: the catch-up wait is now a range, the endpoint comes from the shell, and the platform is `desktop` against the collector's patched branch.
