Telemetry looks good. Low volume TTP but viable. 4 net new samps over L90D, good detection in depth.

One observable - There is similar style rule that matches after a few changes, but only hits 2 of the 91 samps flagged in this PR over L90D, this PR does not lean on profiles, and is a very specific pattern.

- Hunt 1 L90D (Shared Samps)
- Hunt 2 L30D (Multi-hunt)
