Cloud sessions can be handed forwarded plugin settings

Plugins Notable

Cloud sessions can accept a pushed plugin configuration, but it stays off without server values.

Forwarding enabled plugins and marketplaces into a cloud session is built but needs two remote gates that fall back to false.

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.

What

A cloud session can now receive a plugin configuration pushed from elsewhere, carrying only a list of enabled plugins and extra known marketplaces. It is off unless two remote gates, tengu_violin_wood and tengu_violin_amati, both come back true; each falls back to false if the lookup fails, so with no server values this does nothing.

Details
  • The payload must contain exactly the one forwarding key, itself limited to enabledPlugins and extraKnownMarketplaces. Anything else is rejected as "malformed".
  • Applying it, and the marketplace reconcile and install pass that follows, is only allowed for an admitted managed cloud worker. Refusals are reported as not_managed_cloud_worker, entrypoint, disabled and hermetic.
  • If the gate read does not settle in time the outcome is flag_unsettled; a false read is flag_off.
  • Reconcile results are reported under ccr_plugin_forwarding_reconcile.
