* OpenStation — My WordPress: per-term stats endpoint. |
| 4 |
* |
| 5 |
* `GET /desktop-mode/v1/term-stats/<taxonomy>/<id>` returns an |
| 6 |
* aggregated profile for a single category or tag — counts, recent |
| 7 |
* posts in the term, top authors, co-occurring terms, 12-month |
| 8 |
* activity sparkline, milestones. Powers the right preview pane in |
| 9 |
* the My WordPress folder when a term is selected. |
| 10 |
* |
| 11 |
* Permissions: any logged-in user with `read` (default for most |
| 12 |
* roles) — terms are public-facing data on the WP site, so the same |
| 13 |
* cap that lets you read the front-end is enough to inspect their |
| 14 |
* stats. Author archives are also public so listing top authors is |
| 15 |
* not new disclosure. |
| 16 |
* |
| 17 |
* That reasoning covers the term row and the aggregates over its |
| 18 |
* *published* posts; it does not carry to the unpublished posts inside |
| 19 |
* the term, nor to terms of a non-viewable taxonomy. So hidden |
| 20 |
* taxonomies answer 400 unless the caller can manage their terms, |
| 21 |
* every post-level query is scoped to the statuses the caller may |
| 22 |
* read — resolved from each status's registered visibility flags and |
| 23 |
* the post type's cap map, plus the caller's own posts — and the |
| 24 |
* recent list is gated per row with `read_post`. Otherwise a |
| 25 |
* subscriber could read an administrator's private and draft post |
| 26 |
* titles, authors and dates, and the per-status counts would leak how |
| 27 |
* many hidden posts a term holds. The readable-status clause is built |
| 28 |
* in the callback, right above the queries that splice it in. |
