Research direction

Start in mobile/lib/features/channels/message_content.dart at _buildLink, then inspect ImetaEntry.filename in mobile/lib/features/channels/message_media.dart. Run the widget tests near “opens local file links through an authenticated download” in mobile/test/features/channels/message_content_test.dart. Done means a labelled attachment with an imeta filename opens under that filename while links without one retain the link text.

Written by the indexing model from the issue text.

Description

Summary

On mobile, tapping a file attachment link downloads the file and opens it under the link text instead of the attachment's imeta filename. When the label is prose rather than a file name, the opened or saved file loses its real name and extension.

Where

mobile/lib/features/channels/message_content.dart, in _buildLink: the authenticated download is opened with the link text as the file name:

await ref.read(openDownloadedFileProvider)(
  url,
  auth.headersFor(url),
  text,
);

_buildLink already receives the matching ImetaEntry? imeta, and ImetaEntry (mobile/lib/features/channels/message_media.dart) parses filename. It just isn't used here.

Steps to reproduce

  1. Send a message with a non-media attachment whose link label is not the file name, e.g. content [Quarterly report](https://<relay>/media/<sha256>.pdf) with imeta containing filename q3-report.pdf.
  2. Tap the link on mobile.

Expected: the file opens as q3-report.pdf.
Actual: it is opened under Quarterly report, without the .pdf extension, so the system viewer may not recognize it.

Suggested fix

Prefer the imeta filename and fall back to the link text:

imeta?.filename ?? text,

A widget test next to opens local file links through an authenticated download in mobile/test/features/channels/message_content_test.dart can pin it, with a labelled link plus an imeta tag carrying filename.
