Under the hood
Remote headless session attach can now get a device link directly instead of waiting on polled session state
What
When a certain condition is met, attaching to a remote headless session now uses a new linkForServing helper to get a device ID directly, rather than always waiting for and deriving the connection from polled session state. A new failure telemetry action, attach_serve_link, was added to track when this path fails.
Why
This can make attaching to a remote session faster in the cases where the direct path applies, by skipping the wait for polled state.
Something disagreesSomething we can check disagrees with this entry, or the writer said they could not settle it.
The writer flagged doubt
The finding does not specify what condition triggers the direct device-link path.
