John O'Keefe 6fc501b35a docs(stats): Claude-side pinning — all 4 stats endpoints + UNVERIFIED sweep to zero
Stats docs written handler/service-first (summary/this-week/book-stats
new; library-usage frontmatter'd — its body was already accurate).
Registry: 4 entries on services.UserSummaryStats/WeekSummaryStats/
LibraryUsageStats/BookStats. Family-lens note: library-usage 403s an
explicit library_id outside the visible set (431fec0 rule).

UNVERIFIED sweep (7 -> 0), each resolved against the handler:
- device-usage takes NO date params; popular-books takes only ?limit
  (the 'standard analytics date-range params' claim was wrong)
- link_book media_item_id: no validate tag but service-always-written
- push_stats book-ref field set documented (uuid/sha256/title/authors)
- filter_count: confirmed ParseMediaSearchParams machinery + 400 on bad
  filter + 403 visibility
- facets values element shape pinned: {value, display?, count}
- get_config: dynamic key set IS the contract (reworded, no marker)

make test 9/9.

Get Device Usage

Per-device sync activity for the signed-in user.

Example response

{
  "devices": [
    {
      "device_id": "550e8400-e29b-41d4-a716-446655440000",
      "device_name": "Kobo Clara",
      "device_type": "kobo",
      "sync_count": 42,
      "last_sync": "2026-10-24T13:57:01Z",
      "total_time_seconds": 3600,
      "total_time_minutes": 60
    }
  ]
}

Query parameters

None. The handler aggregates the user's full device-usage history — there is no date-range filtering on this endpoint.
