The six answer sources were hand-unrolled inside one 127-line function.
The intent table is a closed set of 7, but this list is open-ended —
Kiwix (#286), RSS (#258), the crawler (#259) and email (#246) each add
one. Each is now a registry entry: a name plus a method on the handler,
walked in order until one claims the question.
Order is unchanged and still load-bearing (memory before the notes-only
pass, #373), the confidence gate keeps its position and semantics, and
every reply string, log line and best-effort failure is verbatim.
