Document the requester picker, as a pair Plain-language page for someone raising a ticket on a colleague's behalf, and a developer guide covering the request flow, why authorisation happens twice, and the three bugs the feature fixed on the way through — the unscoped user list, the name box that silently did nothing, and the requester who was created with no company at all. Two things recorded because they are the sort that get rediscovered the hard way: appending a tenancy clause to an unbracketed OR list binds it to the last branch only, and the `hidden` attribute loses to any author rule that sets `display`, which rendered an empty chip with entirely correct markup. Also corrects a stale line in Tickets.md. It described the reply modal's To/Cc row as "matching the New Ticket modal's requester name / email row" — a row that no longer exists. Rather than deleting the sentence, it now says what changed and points at the new page, because the comparison is the sort of thing someone will go looking for.
