 # Unreleased
 
+- Add independent Group chat / Private chat chips to the trace Type column, using summary message types with a legacy UMO fallback and leaving unknown types unlabeled.
+
 - Reduce trace table header height to 40px using Vuetify's native header-height variable; preserve body row and pager sizing.
 
 - Show the Tokens card total with two-decimal k/M notation while keeping precise counts in its tooltip.

 Traces containing Agent calls add a borderless Tokens statistics card. Its total sums this execution's input (including cached input) and output, displayed with two-decimal k/M notation while the tooltip retains exact counts; hover or focus to inspect input, output, and cached-input counts. Only the latest cumulative snapshot per Agent is used, and separate Agents are summed. Unavailable usage shows an em dash rather than a reported zero.
 
-The Type column precedes UMO. Blue Agent indicates an Agent call; green Command indicates a command-handler call. Both can appear independently on the same trace. Ordinary listeners and event hooks do not count as commands. Summaries provide these flags; legacy command flags are derived for the current page without opening each trace's details.
+The Type column precedes UMO. Blue Agent indicates an Agent call; green Command indicates a command-handler call. Neutral Group chat / Private chat chips appear independently alongside them. Ordinary listeners and event hooks do not count as commands. Message type comes from the summary, falling back to UMO for older records; unknown types have no chat chip. Legacy command flags are derived for the current page without opening each trace's details.
 
 New spans identify calls with `astrbot.kind` and describe execution through timestamps and status. They no longer store `astrbot.action`, `astrbot.end_action`, or `astrbot.duration_ms`; duration is calculated from nanosecond timestamps and `astrbot.handler_type` remains. Existing trace history stays readable without rewriting stored records.
