What

project_read now retrieves images, spreadsheets and binary uploads instead of returning empty content, writing the original bytes to a local file and returning that path.

Details
  • previously non-document attachment types came back with no content
  • downloads are capped at 20 MiB per session
  • one retry when the downloaded byte length disagrees with the reported size
  • verifies the server returned the file that was requested, and that the id is UUID-shaped
  • filename is sanitized and the file is written with mode 0600
  • gated on allow_projects_tool and requires a project bound to the session
Evidence

project_read: server returned a different file.

Strings lifted out of the shipped bundle, so the claim above can be checked against them.
