TC89 — the normal upload path itself, captured (not just the post-hoc read-back)
==================================================================================
The original ingestion of these two fixtures did not capture the actual
POST /document/create-by-file call. Re-submitted both files through the same normal
upload path so the submission itself is visible, not just asserted: deleted the two
existing document entries, then re-uploaded fresh, capturing full request + response,
then re-confirmed the same terminal error status as before. End state is unchanged —
same two files, same two error messages — only the evidence now shows the submission.

At submission time the file is accepted and queued (indexing_status: "waiting") — the
failure is not visible yet at this point, only after processing completes.

}

Both files, submitted through the exact same normal upload path
(POST /document/create-by-file), are accepted at submission time (queued, no error
yet) and only fail once processing actually runs — the truncated file with a
data-format error, the password-protected file with an incorrect-password error.
Neither is ever reported as "completed"; both terminal statuses are "error" with a
specific, accurate message. Same result as the original run this replaces — the
submission itself is now part of the evidence, not just the read-back.
