Fix activity kit stats: switch to get_total_post_views() for per-kit view counts

[Piyopiyo-Kitsune]

Problem

The Activity Kit Stats page shows 0 views for all kits despite Jetpack being connected and the site receiving thousands of daily page views (confirmed via Jetpack Stats).

Root cause

get_jetpack_post_views() was calling WPCOM_Stats::get_top_posts() — which returns the top 1,000 most-viewed posts on the entire site, ranked by accumulated all-time view count. Activity kits went live on Aug 11 and have only 1–2 days of traffic. With years of established courses, lessons, and learning pathways outranking them, the kits don't appear in the top 1,000 and the function silently returns 0 for every kit.

This was confirmed by checking the Jetpack Stats admin page, which shows the site receiving ~5,000–8,000 views per day but only lists long-standing content (Beginner WordPress User, Introduction to WordPress, etc.) as top posts — no activity kits in sight.

Fix

Switch to WPCOM_Stats::get_total_post_views(), which hits the stats/views/posts endpoint and fetches view counts for specific post IDs directly, regardless of site-wide ranking. The kit post IDs are already known from the get_posts() query, so they are passed as a post_ids comma-separated parameter.

Also corrects the response key: the views/posts API uses uppercase 'ID' for the post identifier; top-posts used lowercase 'id'.

Testing

1. Visit the Activity Kit Stats page
2. Views should now show non-zero counts for kits that have been visited

Pull request overview

This PR addresses incorrect “0 views” reporting on the Activity Kit Stats REST endpoint by switching Jetpack Stats fetching to a per-post-ID views API, ensuring newly published kits are included even when they aren’t in the site-wide “top posts” list.

Changes:

• Update the stats REST handler to fetch view counts by explicit kit post IDs via WPCOM_Stats::get_total_post_views().
• Adjust parsing to match the views/posts response shape (including using uppercase ID).
• Add an “Activity Library” item to the theme’s site navigation menus.

Code review findings

The core change is correct — stats/views/posts with the uppercase ID response key is the right endpoint for per-post view counts. But the endpoint's server-side validation breaks two of the four ranges, including the default one, so the "0 views" bug survives in its most common configuration.

1. Blocker: 90d and all ranges still return 0 views (activity-kit-rest.php:187)

The WPCOM stats/views/posts endpoint rejects num > 30 with a 422 (Number of days must be between 1 and 30. — confirmed in the wpcom server source; the public docs also say "Maximum of 30"). This PR sends num=90 for 90d and num=36 for all — and all is the REST route's default. A non-200 response means get_total_post_views() returns a WP_Error, get_jetpack_post_views() returns array(), and every kit shows 0 views on the initial stats page load. Only 7d and 30d actually work.

Serving the long ranges requires summing chunked ≤30-day windows, or a different endpoint for those ranges.

2. period is silently dropped (activity-kit-rest.php:186)

views/posts only declares post_ids, num (days), date, and offset — undeclared args are discarded by the WPCOM JSON API framework, so the 'all' => period='month', num=36 branch encodes an intent the API can never honor. The block now visually mirrors the still-meaningful one in get_jetpack_download_clicks() while meaning something different, which invites a bad "dedupe" refactor later. The views-side range mapping should be rewritten in this endpoint's own terms (days only) with period removed.

3. Unbounded kit query vs. the 100-ID cap on post_ids (activity-kit-rest.php:185)

post_ids accepts at most 100 IDs, but the kit query uses posts_per_page => -1. Once more than 100 activity kits are published, kits beyond the cap silently report 0 views (or the whole call errors and all report 0). Chunk with array_chunk( $kit_ids, 100 ) and merge the maps — or when the kit filter param is set, pass only that kit's ID.

---

Checked and cleared: the docblock updates, wp_list_pluck( $kits, 'ID' ) on WP_Post[], the uppercase 'ID' response key, and get_total_post_views() availability in the jetpack-stats package.

Thanks for the thorough review — all three points addressed in f73fd26.

1. Blocker — 90d/all returning 0 views: Replaced the single call with a multi-window approach. Each window is ≤ 30 days; for 90d and all, three consecutive 30-day windows (offset 0, 30, 60 days) are issued and their results summed. 7d and 30d remain a single call each.

2. period silently dropped: Removed entirely. get_total_post_views() receives only post_ids, num, and date — the three parameters the endpoint actually reads.

3. 100-ID cap on post_ids: Added array_chunk( $kit_ids, 100 ) around the outer loop; results are merged into a single map. The inner window loop runs per chunk, so all combinations of chunk × window are covered.

The all range label in rangeLabel() in index.js was already updated to 'All time (max 90 days)' in a previous commit, so the UI correctly communicates the cap to admins.
