"""Tests for engine ``_build_attachment_messages``.
|
|
|
|
The attachment builder branches on the resolved MIME:
|
|
|
|
- ``image/*`` -> ``ContentBlockImage`` (regression preserved)
|
|
- ``application/pdf`` -> locally extracted text wrapped as ``ContentBlockText``
|
|
- text-family / json -> ``ContentBlockText`` wrapped as
|
|
``<file name="…" mime="…">\\n<content>\\n</file>``
|
|
with escaped filename and content boundaries.
|
|
|
|
Image flows must not regress, and text/PDF attachments are normalized into
|
|
wrapped text context.
