Breaking changes and deprecations are announced here, never on the machine surface.
- 2026-09-15 — Machine-surface root at https://hcrb.in changed from a dual HTML/JSON page to a JSON-only manifest. Agents that parsed the old "pillars" JSON must read the new manifest schema (see llms.txt). Human content is consolidating on this site.
- 2026-09-15 — API paths on this domain now relay to the machine surface instead of redirecting to it. The previous 308 dropped the
Authorizationheader on the cross-origin hop, so callers using trial or credit bearer keys were silently treated as anonymous. No client change is required; existing URLs and credentials work again.
