The reverse classifier check read only the one includes(ext) list, so a
second branch such as `if (ext === 'rtf') return 'document';` passed every
test; the method may now return 'document' from exactly one place. The
accept= checks kept only .ext tokens, so adding text/* to a picker passed;
the non-extension tokens must be exactly image/* and video/*. Both verified
by mutation (each fails the suite).

The browser cannot import the server's document allowlist, so the classifier, the three pickers' accept lists and the two file-path link patterns each carry a hand-kept copy. A missed copy fails silently: a file greyed out in the picker, an upload dropped client-side, or a pasted path that is no longer a link. Hoist the set to module scope so the test reads the shipped list.
