Cloud and remote sessions try to start device registration

Not switched on
Useful2 Signal3
Device Bridge not in their notes

Cloud and remote sessions try to start device registration, which does nothing while the gate is off.

Both cloud attach and remote auth setup call startDeviceRegistration, which short-circuits unless tengu_violin_wood and the allow_remote_sessions policy permit.

Feature flag
tengu_violin_wood Off in both readings

The flag server returned off for the account this site reads and for the anonymous baseline. A reading of off cannot rule out a rollout these two readings sit outside of.

This account: off · anonymous baseline: off · compiled default in v2.1.225: not a boolean we can read

These values were read against a different version of Claude Code, so treat them as the nearest reading available instead of one taken on this release.

Read once, for one account on one subscription tier, against v2.1.225. It isn't a statement about your account. What a flag value here can and cannot tell you

allow_remote_sessions
What

Attaching a cloud session and completing remote auth setup both now attempt to bring up the device bridge for that session.

Details
  • both paths dynamically import startDeviceRegistration and call it with the session id, an access-token getter and the org uuid
  • registration short-circuits on its own enable and egress checks, so nothing happens unless tengu_violin_wood and the allow_remote_sessions policy both permit it
Evidence

startDeviceRegistration

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