# CI checks

| Check | What it fails | Since |
|---|---|---|

| `pgrep-self-match-check.sh` | a `pgrep -f` / `pkill -f` with a bare literal pattern, or `ps \| grep <word>` without a bracket or `grep -v grep`, in tools/, relay/playbooks/, infra/ or packaging/: the pattern matches the shell that runs it (the wave script of 6 October 2026 never started a node on 38 cards because `pgrep -f igneumd-0313` saw the launching shell; a kill file killed its caller the same day). Anchor to the executable's path, bracket the first letter, or use `-x`. Owed (allow-listed, finished measurements): `tools/prover-floor/pc2-*.ps1`, `tools/proving-v1/pc2-*.ps1` (their `pkill -f sp1-gpu-server` becomes `pkill -x`), `tools/repo/fresh-repo.sh:223`, `tools/observer/autosync.sh:22`, and the live devnet's operational scripts the fleet agent does not own: `infra/devnet/restart-hand-nodes.sh`, `infra/seed-nodes/addpeer-from-mac.sh`, `relay/playbooks/shard-test.ps1`, `tools/ci/fixtures/bash-body-ok.ps1`, `tools/ci/pgrep-self-match-check.sh`, `tools/ci/prover-socket-check.sh`, `tools/exec-attacks/net.sh` (their owners anchor the pattern when next touched; the hand-node and seed scripts run tonight and were not edited blind) | 6 October 2026, branch gpu-fleet |
