**Context:** #9306 (merged) added link-preview tags to the invite page. To build the media URLs, the relay looks up the community for the request host. This fixes a problem found in our review of #9306. **Problem:** The invite page waits for that lookup with no time limit. When the database is slow, the lookup can take as long as the pool acquire timeout (3 s) plus the statement timeout (120 s by default). During that time, a person who opens an invite link gets no page. Before #9306, this page did not use the database. **Fix:** The lookup gets 250 ms. If it does not finish, the relay sends the page without the preview tags. A healthy indexed host lookup finishes well inside that, so crawlers still get the tags, and nothing else changes: the media route, the router and the build are untouched. ### Validation - Added test: a host whose lookup never finishes gets the plain page. Without the timeout, this test hangs (confirmed locally; it was killed after 30 s). - The existing `invite_preview` and router invite tests pass. 🤖 Generated with [Claude Code](https://claude.com/claude-code) Signed-off-by: Tom Brow <tomb@squareup.com> Co-authored-by: Tom Brow <tomb@squareup.com> Co-authored-by: studio <dc2fc481343672df31a689840c09299972e704dac592e0da6f18486646a7ee3e@buzz.block.builderlab.xyz>
