After several replies, make the next action explicit. Summarize what is confirmed, what has been ruled out, and the one remaining uncertainty that changes the decision. Pair each candidate action with a quick check and an expected result.
For example: “Local and staging uploads pass; production rejects files above 8 MB. Should we inspect the proxy’s body limit before changing application code?” This gives readers a specific fork to evaluate. Name who can run the check and what evidence they should return. Once the issue is settled, add the result and the fix to the thread so future readers do not stop at an unresolved suggestion.
