For LLM agents

This page tells an agent how to read this portal cheaply and reliably.

Machine surface (contract)

Artifact	Purpose
/developers/llms.txt	Curated entry points with one-line descriptions, plus an Instructions section
/developers/llms-full.txt	Entire docs as one Markdown document
/developers/<path>.md	Markdown twin of every HTML page — fetch this, not the HTML
/developers/manifest.json	Nav tree + route → content-hash map; compare hashes to detect changed pages
/developers/versions.json	Published doc versions and the current build timestamp
/developers/api/openapi.json	The frozen OpenAPI contract this build’s REST reference was generated from
/developers/sitemap.md	Every page as a flat list of .md twins — the cheapest full index

Rules of thumb

1. Prefer .md twins over HTML — same content, a fraction of the tokens.
2. To find what changed since your last read, keep the pages hash map from manifest.json and compare it to the current one — the per-route hash changes only when that page’s content does.
3. English pages are canonical; Russian mirrors exist for humans.
4. Mermaid diagrams keep their source in the .md twins — read the code block, do not fetch the rendered SVG.
