Rails main (e3d5c569) moves Campfire's pin forward ten months. Because
Campfire loads the 8.2 framework defaults, the ones added since then take
effect too, among them header-only forgery protection, Herb as the HTML
template engine, strict Accept headers and immediate blob analysis.
Changes it needed:
- Minitest 6 has no minitest/unit; the test helper no longer requires it.
- Rack::Sendfile is no longer in the middleware stack; DebugLocks goes
before ActionDispatch::Executor, as the Rails guide now says.
- Time::DATE_FORMATS is deprecated; :epoch is registered through
ActiveSupport::TimeFormats.
- Channel test subscriptions expose stream_names; streams is private.
- sentry-rails declares its Action Cable handle_open and handle_close
wrappers private, which Rails 8.2 calls from outside the connection, so
no /cable connection succeeded. An initializer makes them public until
getsentry/sentry-ruby#2972 ships (issue #2975).
- Lexxy renders editor content through Rails' editor adapter when Rails
has one, which asks a mention for its editor partial. It is the same
users/mention partial the mention prompt already inserts.
- redis-client moves to 0.30.1: Rails main's Redis cache store, which
production uses, requires 0.28.0 or later, and assets:precompile
(the Docker build) aborted on 0.25.2.

The job picks the room's members once and then publishes to them one at a
time, as the request did before it. A member who opens the room during that
loop gets the read event in their other tabs and then the older notice,
which marked the room unread again. Both events now carry the server time,
and the sidebar ignores a notice dated before the room's latest read. The
notice still moves a direct room to the top.

Since the unread rooms stream was scoped per user, posting a message
publishes the room id once to each member of the room. Each publish is a
round trip to Redis, made one after another inside the request, so the time
to post a message grows with the size of the room and in a big room is far
more than the rest of the request.
The fanout now runs in Message::BroadcastUnreadRoomJob, so the poster no
longer waits for it. Who gets the notice and what it says are unchanged.

UnreadRoomsChannel streamed from a hardcoded global name, and every message
published its room id to it. Any authenticated user, including one with no
memberships at all, could subscribe and watch which rooms were active and exactly
when, across every closed room and direct conversation on the account. The browser
filters ids it doesn't recognise, but that happens after delivery.
Its sibling ReadRoomsChannel is already scoped per user; this mirrors it, and
message creation fans the notice out to the room's members instead of broadcasting
it to everyone. No message content was exposed either way, only the timing.
Message content is delivered over turbo streams, which ran on the stock
Turbo::StreamsChannel. That channel verifies the signature on the stream name and
nothing else. The name carries no expiry and no binding to a user, so one read off
the page while a member kept working after the membership was revoked.
Revocation made this worse rather than better. Membership#after_destroy_commit
disconnects the user with reconnect: true, and the client replays its subscriptions
on the new socket: RoomChannel re-checks membership and rejects, while the turbo
subscription re-verified only the signature and was accepted.
RoomMessagesChannel re-checks membership on every subscribe, deriving the room from
the verified stream name so there is no parameter to point elsewhere. Since the
subscriber names the channel it wants, the stock channel would otherwise be a way
around that check, so it now turns these stream names away and this is the only door.
