Email becomes a DeliveryChannel driven by rules, and the Team pipeline stops being
its own thing. `teamNotify.forumPost` now emits an event; a rule decides who is
mailed, through which template, and how often at most. One walk goes forum write
-> events.emit -> rule -> outbox -> worker -> email channel -> template -> SMTP.
Seven decisions settled by the org lead before any code:
- email only moves; the push tickle and the Discord bridge stay direct calls
- the EVENT carries its access-checked audience, and `members` resolves to it
- the four Team rules are seeded DISABLED, with an admin banner and a note
- team_notification_prefs stays, read by the engine as a scoped preference
- the payload wins and a structural projection fills the gaps
- the digest keeps computing at send time; only its state generalizes
- an unsubscribe token turns off the channel it names, and nothing else
Three defects found while building it:
- `email.button` never absolutized its href, while image and itemList both
did. Every rule-driven CTA would have been a dead relative link, because a
trigger's url variables are validated site-relative by construction.
- Phase 4a enqueued digest-mode recipients for a drain that Phase 6 decided
not to build. An outbox row snapshots the payload and so has none of the
three properties the digest design exists for, including the security one.
- the digest's send-log row carried no address_hash while the instant row
beside it did, which would have made half the mail uncorrelatable in Phase 9.
Also: engagement_digest_state + a replay-safe backfill, engagement_outbox.scope_key,
a v2 unsubscribe token that still verifies v1 forever, and the canonical
/public/engagement/unsubscribe pair with the old /public/teams path kept
permanently — mail is not editable once sent.
Verified with 1464 server tests, 324 client tests, and a live rig (MariaDB +
Mailpit + a real Team) covering the instant mail, the digest, the generic
template, a pre-migration unsubscribe link and the backfill's replay-safety.

Found walking the live rig, which is the only place it could be found: every unit
test and the settings screen itself send every row, so the bug was invisible to
both.
`PUT /auth/me/notifications/teams` documents itself as replacing the whole set. It
did not — it wrote the entries it was given and left every other preference
standing. So `{"teams": []}` cleared nothing, which is precisely the body the route
requires the array for: the field is mandatory even when empty so that clearing
everything is expressible, and it was the one thing that did not work.
A Team the caller could have named and did not now returns to its defaults. RESET
rather than deleted, and the difference is `last_digest_at`: that column is the
digest worker's state and not a preference, so dropping the row with it would make
every visit to the settings screen re-open a day-wide digest window and mail
somebody a summary they had already read.
Walked again after the fix on the real database: the empty set clears, an entry
naming a Team the caller is not in is still dropped, and the digest stamp survives.

A notification feature is mostly things that correctly do NOT happen, and each of
these is invisible until it goes wrong in production: a departed member and a
revoked guest are not recipients; a mute subtracts per Team and leaves the user's
other Teams alone; the author of a post never receives the notification about it;
forums switched off silences the forum streams including the digest; a Team's
first roster wakes nobody; a failed send does not stamp `last_digest_at`.
Two real defects came out of writing them.
`Number(null)` is 0 and 0 is an integer, so a null in a caller's id list survived
`filter(Number.isInteger)` and rode into an IN clause as user id 0. No row has id
0, so it was harmless — which is exactly why it would never have been noticed.
Fixed in all three places that filter ids.
`recipientIds: db.recipientIds` in the model captured the function OBJECT at
require time, so the layer below could never be substituted. That is not only
untestable; it means the model was not really the seam it claimed to be. Wrapped
so `db.x` resolves at call time.
The registries catalog assertion is now an exact five-element list, so a
shard-content stream creeping back into core's registration fails here rather
than shipping.
