/**
|
|
* index_config/updates_feed.php
|
|
* ─────────────────────────────────────────────────────────────────────────────
|
|
* Lightweight JSON endpoint consumed exclusively by the JS auto-refresh in
|
|
* index.php. Returns the full updates array (JS handles pagination client-side
|
|
* so every poll can detect new posts regardless of which page is visible).
|
|
*
|
|
* Usage: GET index_config/updates_feed.php
|
|
* GET index_config/updates_feed.php?since=<ISO-timestamp>
|
|
*
|
|
* The optional ?since= parameter lets the client ask "give me only posts newer
|
|
* than this timestamp" so it can detect new arrivals without comparing full
|
|
* arrays.
|
|
*
|
|
* Response:
|
|
* {
|
|
* "ok": true,
|
|
* "total": <int>, // total posts in the feed
|
|
* "new_since": <int>, // posts newer than ?since= (0 if not supplied)
|
|
* "items": [ … ] // full array, newest first
|
|
* }
