Phase 7 of docs/member-archive.md, in part. Three chat types --
`TYPE_ARCHIVE_REQUESTED`, `TYPE_ARCHIVE_SENT`, `TYPE_ARCHIVE_RECEIVED` -- so a
room that fills itself in explains itself once.
Without this the archive is entirely silent by design: it files no line per
applied payload, because `ChatMessage` has an `autoGenerate` primary key and
every payload would mint a fresh row on every pass of the sweep. The result was a
member joining a working group and watching a room populate with no account of
where any of it came from, which is worse than the noise it avoided.
**One line per archive, not per page.** The received line is written when the
request stamp is cleared, which is as close as this can get: an archive's pages
are not distinguishable from each other at apply time, and clearing the stamp is
exactly the moment a catch-up stops being pending. There is a test that delivers
a payload per page, backwards, so the sweep runs repeatedly over many pages, and
asserts the transcript holds two lines.
**A push behind a Welcome writes nothing**, because the room was never asked. It
lands before the member has opened the room, and "caught up on work you have not
seen yet" is a line about nothing. Also tested.
**The received line names no sender.** An archive can be assembled from pages
sent by more than one member, so attributing the catch-up to one would be a guess
dressed as a fact. The sent line does name its recipient, written into the
content the way the invite line writes one -- which does not follow a rename, and
is the accepted cost for a line about something that happened once.
**Content is whole sentences**, so these stay out of the AUTHORED sets and
nothing prefixes a name to them. And they are added to `ARCHIVE_TYPES` with a
matching arm in the transcript, because the failure mode for a missed set is
silent: the line renders as a chat bubble, looking exactly like a member having
said "Caught up on 12 items". Icons per type rather than the `PanTool` fallback.
**Two items from this phase are deliberately not done**, rather than written
without the app in front of me: the banner saying a room is catching up, and a
"Send history" action on the member row. The first is UI state plumbed through a
view model into a layout and the transcript line covers the same ground; the
second is a convenience, since both real paths are already automatic. Both are
written up in the plan as outstanding, along with the thing this phase was also
meant to say and does not: that an archive does not make its recipient able to
sign, and does not carry the translated text.
