remote-run.sh gains a checkout mode used by lib.sh: git checkout -- . and git clean -fd (target dirs, the sha stamps and
ignored files kept), fetch, branch at the commit, then a clean-tree check; the overlay follows. Before this, the rsync of
uncommitted files stayed in the box's tree and the next commit's git checkout -B refused with 'local changes would be
overwritten'. remote-run.sh --self-test reproduces the dirty tree (edited tracked file, untracked file, target dir, sha
stamp), shows the plain checkout refusing and the mode landing clean on the new commit; it runs in ci.yml and passed on the
Mac and the box; a live dirty-then-clean pair on the fork worktree passed too. Plan: section 5, gotchas of the first day.

Main's decision of 6 October 2026. CLAUDE.md 'Running agents on this Mac': every Linux and Windows cargo build and every
Linux test suite goes to igneum-build-1 through tools/build-remote.sh and tools/cross-remote.sh; the PCs keep GPU and
Windows-runtime jobs; the Mac keeps macOS binaries, the DMG and Metal tests under the lock. -Wl,--no-insert-timestamp in
cross-remote.sh, proto-cuda/windows-node/cross-build.sh and jobbuild.rs (two box builds byte-identical, verified).
The empty-commit class: tools/ci/commit-string-check.sh (self-test in ci.yml, shown firing on a Mac worktree build and
passing on a box build) runs on every igneumd from the three build scripts; push-build-inputs.sh adds node.commit_full,
the PC job writes a minimal node/.git from it at extract and cleans kaspa-build-info on a new commit (4 jobbuild tests
pass, run on the box); cross-build.sh refuses a worktree and cleans on a new commit. Plan: second worktree's clean build
1 min 18 s with sccache 604 hits of 993.

remote-run.sh runs on the box behind BR_* exports: slot, sccache stats, the RESULT line and one JSON line per run in
/srv/builds/_log/builds.jsonl (v 1, id, host, tool, worktree, crate, kind, command, target, branch, sha, label, agent, slot,
wait_s, queued_at, start, end, secs, exit, compiles, sccache, load_end, artefacts; written on success, failure and the 2 h
slot give-up), the label ending in '; agent=<name>' (IGNEUM_AGENT, default the worktree). The remote checkout is a branch and
build-remote.sh cleans kaspa-build-info (release profile) on a new commit, so the box's igneumd carries its commit hash
(no Mac worktree build does: .git is a file there). cross-remote.sh fetches the GCC 13 runtime DLLs beside an exe that
imports libstdc++-6.dll. The plan holds the three benchmarks: clean node build 1 min 27 s (Mac 12 to 18 min), incremental
7 s (Mac 2 to 15 min), Windows cross 1 min 44 s (Mac 4 min 49 s to 12 min 28 s), their consequences and the proposed rules.
