Make relating discoverable and pleasant: a hint on posts with no relations, and
a real candidate picker on the edit page.
- post page: when a post has no relations AND the viewer is logged in, show a
subtle "No related posts yet — add some" hint linking to the edit page;
anonymous viewers still see nothing.
- GET /<slug>/relate-options?q=&offset= — SX endpoint returning one page of
candidate rows (HTML <li> fragment): every post except itself and ones already
related, narrowed by q (case-insensitive title/slug substring), title-sorted,
paginated by host/blog--picker-limit. Public read; the relate POST stays
guarded.
- GET /relate-picker.js — small vanilla glue (debounced live filter +
scroll-to-load-more) served from a route. The host serves static HTML (no SX
island hydration), so the interactive layer is a cached script, not an island;
data-slug on the input carries the post to it.
- edit page: the plain "slug to relate" box becomes a filter input + scrollable
results list (#relate-filter/#relate-results) populated by the script; each row
is a one-click relate form.
8 tests: endpoint lists/excludes-self/filters-by-q/excludes-already-related, JS
route content-type + glue, hint shown logged-in / hidden anonymous. 238/238.
Verified live: hint (logged-in only), candidate rows, q=filter, JS route
(node --check OK), edit picker UI with data-slug.
