When a live artifact watch fails to start, Claude Code now decides whether the failure looks like a transient server problem rather than a permanent one, and routes it to the slow stall-style retry instead of the fast consecutive-failure backoff. A failure counts as a temporary outage if the server replied with a retryable status, or if the request produced no reply at all and hung for at least 10 seconds. Neither of these markers existed on this error path in 2.1.248.
- The retryable-status test returns true for HTTP status 500 or above, 429 and 408; such a status attaches an
unavailablemarker to the startup response. - A startup error code of
boot_request_errorattaches anoAnswermarker, meaning the request errored out with no reply. - The startup builder records the time just before the request is issued, so a hung startup can be measured; a
noAnswerresult plus elapsed time of at leaststallThresholdMs, the reconnect timing default compiled at 10000 ms, counts as unavailable. - The failure helper gained
unavailableandhttpStatusoptions and passes astalledflag plus the HTTP status into the reconnect scheduler. - All of this sits inside the live-watch feature, which is off unless the
tengu_slate_lanternflag is switched on for your account.

Strings lifted out of the shipped bundle, so the claim above can be checked against them.
tengu_slate_lantern Off by default, switched on for this accountThe shipped code defaults this off, and the flag server returned on for the one account this site reads on this version. That is the reading that makes the entry above worth a second look, and it still says nothing about your account.

A reading is one sample. Claude Code evaluates its flags remotely, so no client sees the targeting rule behind a value and this says nothing about your account.
