Four assertions drifted from the current JoinSpace modal, carried over
when the file was renamed from the old JoinServer component in fc06e25
without being updated:
- Placeholder was expanded to cover URL-form invite input
('e.g. abc123' → 'e.g. abc123 or https://instance.com/join/abc123').
- 'shows validation error when submitting empty code' asserted a code
path that no longer exists: the submit button is now disabled when
the trimmed input is empty (JoinSpace.tsx line 166), so clicking it
is a no-op and the 'Invite code is required' error from the parser
is unreachable from the rendered form. Replaced with an assertion
that the button is disabled while the input is empty — the actual
validation UX.
- joinByCode signature took on a second `origin` argument during the
S2S DM unification + federated-join work (spaceStore.ts line 69).
parseInviteInput returns { code, origin: undefined } for a bare
code, so the call is `joinByCode('my-invite-code', undefined)`.
Assertion updated to match exactly.
No code behavior change — tests now reflect actual behavior, which
was already correct and deployed. Closes backlog #28.
