Reviewed and rebuilt on current main (the old branch conflicted). Kept findings 1-3 (ticketOptionsQueryKeys builders, byte-identical keys) and 6 (ticketsQueryKeys.detail('__none__'), same key as the old literal). Dropped findings 4 and 5: both imported from @/hooks/admin-query-keys (adminQueryKeys.organizations.all, SCHEDULING_LINKS_KEY), a module that does not exist in this repo, so the build would have failed. tsc --noEmit passes with 0 errors.
