Here's the situation. Someone asks a good question about a specific rule interpretation. User 1 responds with an answer along the following lines:
The rules on page [x] establish this as a case of [thing], which means it must follow the rules on page [y]. Contrast with case [other thing] which behaves differently, and it's clear that [answer].
User 1's reasoning is valid, and they arrive at the correct answer.
Looking at the question, I realize that I know an official source (say, an Errata or Sage Advice) that explicitly states the answer to the question being asked.
I definitely think I need to provide this information. An answer relying on reasoning and interpretation of the rules is open for debate and may not satisfy everyone. However, a direct and official ruling is beyond debate and provides an additional weight of authority to the answer. However, I'm unsure how to provide this information.
What should I do?
- Post a competing answer relying on the source instead of exegesis?
- Add a comment with a link to the source?
- Edit the answer to include a link to the source?
- Something else?
