The local branch was reusing friendRequestPayload (built for
friend_request_received with user=sender) for the sender-side
friend_request_sent broadcast. Tab B on the sender would render
the sender's own avatar where the target's should appear.
Match the federated branch — sent broadcast carries target.
Refactors the POST handler into handleLocalFriendRequest + handleFederatedFriendRequest helpers. The federated branch resolves the target domain, ensures peering, looks up the remote user, creates/hydrates a replicated stub, and writes a transactional (friend_requests + mutation_log + outbox) event with relayMessageId set. Also exports hydrateReplicatedUserProfile from federation.ts and adds the T11 happy-path test.
Per code-review suggestion: add a brief comment explaining why
module-level sqlite/testDb/app reassignment works (mock getter
closes over the current binding) and what would break it
(top-level it, .concurrent describe). Prevents a future foot-gun.
Registration canonicalizes usernames to lowercase (auth.ts:32),
but the friend-request endpoint compared with strict eq() against
raw user input, so 'Bob' returned 404 even when 'bob' existed.
Trim and lowercase before lookup, matching the rest of the auth
boundary. Empty-after-trim now returns 400 (was: 404).
Tests appended to social.test.ts as a second describe block
sharing the harness from Task 1.
Tombstoned users, replicated federated stubs, and users with
discoverable=0 were all surfacing in Add Friend search results.
Add the three WHERE filters that /api/social/discover already
applies. Federated users continue to be surfaced via the
client-side cross-instance fan-out in socialStore.searchUsers.
New tests: social.test.ts covers all five filter cases plus
existing self-exclusion and displayName-match behaviours.
