Prefetch System Context Optimization

Entry

ChangesSection of the release
What

System context is now prefetched more intelligently based on trust status.

Details
  • In non-interactive sessions, prefetch runs immediately
  • In interactive sessions, only prefetches if trust has been established
  • Logs prefetch status via prefetch_system_context_* telemetry events
Evidence

tR7() at line 543352 (prefetch logic, contains "prefetch_system_context")

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