-### Runner limits (all workflows on scotty-git)
-
-Every job on the shared scotty-git runner is limited to **1.5 GB of memory**, so that no workflow can
-take down the git server it runs next to. Each job can read the limit from the environment variable
-`SCOTTY_GIT_JOB_MEMORY_LIMIT`.
-
-**If a step fails with `exit code 137`**, it was stopped because it used more than 1.5 GB. Common
-fixes: run tests with fewer parallel workers, avoid loading whole datasets into memory, or split the
-job. `kaniko-build` prints this explanation itself. For other steps the runner can only report the
-exit code, so this is the place to look it up. If your workload genuinely needs more, ask the
-scotty-git admins (every memory stop is logged on the runner: `journalctl -t ci-memory-limit`).
