🎯 Functional Correctness | 🟠 Major | ⚡ Quick win
Resolve the MD thread before sending the summary.
autopost_md_summary can receive thread=None because safe_create_thread returns None on failure. The current md_msg.thread check does not perform _resolve_message_thread’s fetch_thread() fallback, so it can miss an existing uncached thread. If thread creation then fails, md_msg.channel.send posts the summary in the primary channel, which the MD documentation reserves for the graphic embed.
Use _resolve_message_thread and suppress the summary when no thread is available.

Correct the IEM image recovery URL.
fetch_md_details_iem uses /pickup/mcd/mcd{padded}.png. When _upgrade_md_message retries an image with no cached file, it passes the URL at line 581 to download_single_image. If the SPC image is unavailable, the missing /mcd/ segment can leave image recovery without a usable IEM result.
-iem_image_url = f"https://mesonet.agron.iastate.edu/pickup/mcd{md_num.zfill(4)}.png"
+iem_image_url = f"https://mesonet.agron.iastate.edu/pickup/mcd/mcd{md_num.zfill(4)}.png"This affects delayed image recovery for posts without a cached image. It does not cause a broad bot availability failure.

Summary
Mesoscale Discussions (MDs) previously dumped raw discussion text directly into the primary weather channel (
SPC_CHANNEL_ID), creating massive text walls that degraded alert readability.This change isolates the full discussion text and automated summary into an attached Discord thread on the MD message, leaving only the primary graphic embed in the main alert channel.
Note
The primary alert embed in the channel continues to host the graphic image and the interactive summary button for situational awareness.
Important
If thread creation fails (e.g. permission or rate limit), discussion text is gracefully suppressed from the main channel rather than falling back to dumping raw text walls into the alert channel.
