Trusted-device proof is renewed, not just reloaded

Under the hood
Useful2 Signal3
Auth

Trusted-device proof is renewed once per run instead of just reloaded from disk.

What

The client that streams sessions now renews its trusted-device proof once per run, re-enrolling with the previous token rather than only reloading whatever was on disk. If renewal produces nothing, the stored token is cleared.

Details
  • Renewal runs at most once, guarded by an internal flag, and falls back to a plain token load if re-enrolment fails.
  • A failure is logged and the client simply sends no trusted-device header, so requests continue unauthenticated by device rather than erroring.
Evidence

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