remote-run.sh checkout_tree ran `git clean -fd` on the box mirror before every build from any agent, so the attack rows
lost attack-f3/, attack-f1-venv/ and tools/attack/*/target to each other's builds (7 October 2026, 09:2x UK). The clean now
also spares the fixed prefixes attack-*, scratch-*, target-attack-*, .build-remote.log and every glob in the mirror-local
.igneum-scratch-spare (one per line, # comments, the file itself spared), keeps the target and stamp excludes and still runs
without -x. The clean-tree test asks `git clean -nd` with the same excludes instead of filtering the status list, so a spared
dir is not "not clean". --self-test: a fixed-prefix dir at the root and nested, a declared dir and the spare file survive, an
undeclared dir is removed. tools/ci/scratch-spare-check.sh in the pre-push gate fails when the clean line loses the spare
arguments, spare_args stops reading the file, a fixed prefix goes, or -x appears. docs/plans/build-server.md R4a says how a
lane declares its prefix.

Three classes from the 0.3.17 night. (1) bash reads a script incrementally: tools/build-remote.sh was edited while a four-minute remote
build ran, the running copy continued at shifted bytes and died with a syntax error after the build had succeeded on the box; the
four long-running tools (build-remote, cross-remote, workers-remote, move-hand) now keep their body in one brace block ending in exit,
parsed whole before a line runs; tools/ci/whole-body-check.sh (in the gate, self-test with a block-less copy) holds the shape.
(2) A fork build pairs with the igneum-pow of the igneum worktree it sits in: a fork at 12153428 under a master worktree failed in
kaspa-pow four minutes in (no chain_program_shadow; master's igneum-pow predates release-0.3.17's); build-remote.sh says the
pairing on its first line ('pairs with igneum 6f8d7a7e (detached): igneum-pow 0.2.0') and the JSONL line carries pairs_with.
The first version of that line used '[ -n ... ] && echo' inside an assignment's $( ) and set -e ended the script on the false
status; fixed. (3) move-hand.sh restart <hand> [--digest <hex>] [--go]: after binary installed a release, restart ONE unit and read
it back (first exec line, commit string in the running binary, digest against the wanted one, igneum_getNodeInfo powEngine over the
node's loopback EVM RPC); the digest readers tolerate a missing line.

The reset itself has been master's behaviour since 9df9688 (remote-run.sh checkout_tree: git checkout -- . and git clean of the
overlay files, target dirs and stamps kept, before the branch checkout); the UI lane met the class again from worktrees whose
tools predate it (remote-run.sh is piped to the box from each worktree per build). The check reads checkout_tree() and fails
when the reset and the clean do not both come before the branch checkout; self-test: the real script passes, a copy without the
reset fails, the same lines moved after the checkout fail. cargo-audit: already owned by provision.sh step_cargo_tools
(b2262e5), confirmed ok (0.22.2) on the box; nothing added. Gate GREEN, 33 checks.

The fleet's 22:09 UK incident (a Mac-side pkill -f <log file name> matched nothing, the roll-everything script lived on and wiped a held box) and the day's two pgrep self-matches are one class. The check flags pgrep -f / pkill -f with a plain literal (every one on a line), any pgrep/pkill on a file-name shape, and ps | grep with a literal; it allows the bracket form, -x, -F pidfile, kill $(cat pidfile), a variable and a full path; 11 banned and 16 allowed shapes in its self-test; 0.15 s over the tree. The 25 pkill -f sp1-gpu-server inside bash -c bodies (which matched the calling bash) are pkill -x; the other 11 literals take the bracket form; prover-socket-check accepts both. Row R in the record; the CLAUDE.md rule names the check and covers pkill and file names.

The first master push through the gate died inside remote-run.sh's self-test: its mirror push ran this repository's hook against the fixture tree. Shown fixed by a push to a local bare repository (the real hook, GREEN).

168 non-green runs since the first workflow run were classified (docs/analysis/ci-failures-2026-10-06.md): 102 were tree checks that finish in under 25 s on the pushing machine, 40 were GitHub-side refusals nobody saw.
tools/ci/pre-push.sh is the one list of fast checks; ci.yml's site job calls it with --ci and the pre-push hook with --hook (full gate for master and release-*, structural checks for other refs; never writes into the worktree). tools/ci/export-exclude.txt lists research documents outside the public export list, pruned by identity-check.sh and by the mirror's sync.sh (self-test: an excluded path may quote the patterns, an exported one may not); polish.md and this record are its first entries, which makes master green. tools/ci/windows-paths-check.sh (colon, trailing dot or space, reserved names, over 240 characters) runs as the pre-commit hook on staged paths and in the gate. tools/ci/red-watch.mjs plus the red job on the box's runner record one line per failed master or release-* run to /srv/ci-red/red.jsonl; igneum-ci-red.timer posts each once to the updates channel. pow and sims read IGNEUM_CI_RUNNER for the box. no-foreign-tree-writes.sh no longer exits silently on its warning pipeline under pipefail.
