A colleague analysed his ExpenseTracker build after the toolkit update. It still showed a full mxbuild on every change: 45.5 min in total, 57% of all exec time. His project's bin/ had 15 scripts that differ from the toolkit, among them exec.sh and lint-gate.sh. sync-project.sh never overwrites a hand-edited copy, so the speed work (#587, #590) never reached his project, and nothing said so.

What changes

1. doctor, Machine health. The check looks at bin/exec.sh, bin/_common.sh and bin/lint-gate.sh. If one lacks its speed-fix marker, doctor warns "speed fixes not active in this project: older local copy of bin/…". The markers are gate_kind_decide, mxtk_mx_check_to_mxbuild and lint-receipt-ok. The warning uses advise, so the exit code doesn't change.
2. doctor, Recommended fix. The fix now leads with sync-project.sh <project> --upgrade-bin …. When exec.sh is stale, the command always upgrades its _common.sh with it, and each copy is backed up. This comes before the Gate-mode, sync-folder and machine-speed advice, because until the scripts are current every bench number measures the old path.
3. sync-project.sh known_fix_note. It now names the speed fixes on a hand-edited exec.sh that has the exit-code fix (fail_rc) but no gate_kind_decide. It does the same for a _common.sh that has _mxtk_has_model but no mxtk_mx_check_to_mxbuild. Older copies keep their existing, older note.
4. skills/speed-setup.md. Taking the current scripts is now the first fix. Claude shows each local edit in one line and asks before replacing anything.

Evidence

• Field run. I used the real pre-Exec speed: mx check gate by default, doctor performance check, Windows overhead fixes (#584, #585) #587 exec.sh, _common.sh and lint-gate.sh, taken from a4d701af^, with a local edit added to exec.sh.
  • doctor names all three and prints the upgrade command.
  • sync --dry-run names the speed fixes on exec.sh and auto-refreshes the two unedited copies.
• test-doctor-bench: 72/0. New case 8d covers:
  • a stale exec.sh is named;
  • a current lint-gate.sh is not;
  • the upgrade command comes before the Gate-mode advice;
  • no warning once the script is current.
• test-bug12-sync: 64/0. New case T1c checks that the speed note fires and the exit-code note stays silent.
• Checks: check-scripts, check-portability, the leak guard and check-pr-discipline are all clean.

Risk

• More warnings after the pull. Every project with an older edited exec.sh now gets one more WARN line and a different first Recommended fix. That is the intent; the exit code is unchanged.
• Marker greps. The check could miss a hand-edited copy that kept the marker name but removed the logic.
• Not run on Windows.
