What the reviewer found
PostToolUse on Write|Edit runs node scripts/check-design-tokens.mjs for files under packages/frontend/src, which diffs the branch against origin/main with git and regex-scans added lines for raw colors, px font sizes and similar token bypasses, feeding findings back as additionalContext. Read-only local check; no network and no writes.

What the static scan said
The 26-rule scan found nothing in this file; the review read it anyway.
How this review was made
Fable 5.1 read the files above on 7 September 2026 and answered three questions: is it dangerous to whoever installs it, is each scanner finding real, and what should the installer know. The verdict is bound to the file's hash; when the file changes, it is scanned afresh and reviewed again. A script that changes while the definition does not is not re-reviewed — that is a known gap. How the scan and the review work.
