Template telemetry emits only from the gated device-hook handlers.

What

Three more event shapes cover the template path: a per-run event with template id, outcome, duration and dropped fields; an upload event with outcome, template and byte count; and one for a registration lease expiring. Emitted only from the gated device-hook handlers.

Details
  • The existing registration event gained a count of templates installed alongside those awaiting upload and those refused.
  • It also records how long the handler waited for the account flags, capped at 5000 ms, and whether it shared an already in-flight flag read.

Strings lifted out of the shipped bundle, so the claim above can be checked against them.
