🔔 PR #1722 has been merged

QQ local file upload support has been implemented in #1722 which was just merged to main.

What's already covered:

• Local file → base64 upload via /files API
• max_base64_file_size_mib config option
• Inbound attachment download and storage
• Two-step upload flow (upload → send with file_info)
• Comprehensive test coverage

Potential follow-ups:

If you'd like to contribute additional features, can rebase onto latest main and focus on:

• File caching (file_info cache to avoid duplicate uploads) - this is in your PR
• Retry mechanism with exponential backoff
• File name preservation

Your media.go implementation has some nice ideas (caching, retries). Would you like to close this PR or rebase and contribute those features as a follow-up?

@zboya Hi! This QQ multimedia file push PR has been quiet for over 2 weeks now. I'm closing it for housekeeping. If you want to pick this up again, just reopen it and we can continue from where you left off!
