Compute the To/Cc/Bcc lists for an outbound reply, shared by every
sharingModel: "message" (email-style) connector so recipient resolution
lives in ONE tested place instead of being re-implemented — and
re-misimplemented — per connector.
Three cases, in priority order:
Platform-resolved recipients (recipients non-null): the note carried
a curated recipient set and the runtime resolved it to addresses + roles,
with the acting user's own identities already removed. Authoritative. This
is the only case that can carry a display name — it comes from the
resolved contact — so connectors relying on the other cases get name: null.
Access-contact fallback (recipients null, accessContactEmails
non-null): header participants are narrowed to that set; curated addresses
not on the message are folded into To. Self is excluded via selfEmails.
Reply-all (recipients null, accessContactEmails null): reply to the
original participants (From ∪ To → To, Cc → Cc), minus self.
Self-reply fallback: a self-email thread — a message you sent to your own
or another linked address — otherwise resolves to no recipients, because
every original participant is you and each case above removes self. When the
result is empty AND the original message had no non-self To/Cc participant
(i.e. this is a genuine self-thread, not a mixed thread narrowed to self) AND
every original sender is self, the reply is addressed back to the original
sender (headerFrom) so it stays deliverable. The connector still sends as
its own mailbox — for the copy you received in, that mailbox is the original
recipient.
