Claude Code v2.1.260 ·

New remote-controlled acquire-timeout setting for a lock/queue primitive

A lock primitive's timeout can now be remotely tuned, though no server value is set yet.

A lock/queue primitive's acquire-timeout handling was replaced by Wbt(), which reads a remote numeric setting tengu_cobalt_plinth_sill and, if it's a finite number of 0 or more, uses Math.min(Math.floor(e), L7) as the timeout. The prior strict input-validator for opts.acquireTimeoutMs is gone. tengu_cobalt_plinth_sill defaults to null, so absent a server-pushed value, the code falls back to the existing constant jvn, leaving the new remote-tunable branch present but unexercised by default.
