What
On remote runners, small marker files in /tmp written by the runner are parsed into outcomes: done, yielded, aborted or timeout, with elapsed seconds, plus a prefetch state file giving phase, run counts, age of the last success and an index. Reads do not follow symlinks, do not block, and stop at 4KB; a missing file reports absent. A timer for runner prep steps was added too.
