+`sourceEventSeq` is optional and success-only. When present, it names an earlier non-command event in the receiving session log; `command/done` persists the same reference so a client can combine the command lifecycle with that domain projection without parsing `text` or relying on adjacent rows.

 ## Discovery and parsing views
 
 Adapters receive handler-free immutable descriptors after scope resolution. `parseCommand()` returns `ParsedCommand` before registry resolution; syntax-valid input can still name an unavailable command.
