  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.
