The naive `new Date(executedAt).toISOString().slice(0, 16)` round-trip on every keystroke silently shifted the hour by the local TZ offset (Europe input field is local-time but we kept reformatting via UTC), so the user could only edit the date — the time component snapped back to UTC every render. Fix: keep the local state in `YYYY-MM-DDTHH:MM` form (`executedAtLocal`) and only convert to/from a UTC ISO at the boundaries — initial sync from server and submit. Two small helpers `isoToLocalInputValue` / `localInputValueToIso` carry the conversion explicitly. Also tightened the useEffect on both Red and Blue zones to depend on `test.id` instead of the whole `test` object, so polling refetches no longer wipe an in-progress edit (the 15 s activity poll returns a fresh object reference even when the row's contents are unchanged).
