  description: Public, unauthenticated cross-content search over hydrostor.ca — newsroom posts, static pages and
    the A-CAES project portfolio in one result set, each result carrying its id, title, canonical URL, type and
    subtype. Verified live at 200 searchable objects on 2026-08-22. This is the single most useful entry point for
    an agent that does not already know the content model.

    describes the anonymously readable WordPress REST content API served from hydrostor.ca, which the site exposes
    as a self-describing route index. Every path, parameter and schema here was read from the server's own route
    index and HTTP OPTIONS documents on 2026-08-22 — nothing is invented.
