Fixed on master:

- `2b8e4cf5aa` (peer-4-campus, 2026-07-29) — terminate the `boundary=` value at
  the end of the header line, bound the search to the part's own folded
  `Content-Type` field, reject an empty boundary, and handle the white space
  RFC822 permits around the `=`.
- `05168cb2e6` (stocks-3-arch, 2026-07-29) — share the match counter across the
  recursion so `index` enumerates across nested containers.

Leaving this open pending an end-to-end Terminal Server read of an affected
message: the validation above exercises `smb_getattachment()`,
`smb_getplaintext()` and `smb_countattachments()` directly, not
`download_msg_attachments()` calling them.
